Note: The nut on the screw has been adjusted before the machine leaves the factory and the user is not allowed to adjust or disassemble any part of this part during use. In addition, the hydraulic oil should be replaced once a year, and the large floor area is itsdisadvantage. Because there is no need for hydraulic device, there is no trouble of replacing hydraulic oil, and it is very environmentally friendly. (4) The gripper has a large clearance at each fit. } Now only to strengthen the rib roller cutter as an example of introducing the lower die of the cutting tool roller. Your email address will not be published. After using the mold, clean the mold, place it neatly, wrap it with a protective film, put it into the mold box, put it in a fixed position to prevent the mold from being bumped, burr, or fall into the dust, rust and affect the next use. The filter cartridge used in this hydraulic system is a disposable cartridge, cannot be cleaned to improve its dirt-holding capacity, if the filter alarm, it should be immediately and can only be solved by replacing the cartridge, this point must be emphasized. For mild steel with a thickness of 1.2mm, the gap is calculated as follows: 1.2mm0.2=0.24mm, 1.2mm0.25=0.3mm, so the recommended clearance is 0.24mm~0.3mm. The minimum safety distance from the bending edge (inside) is 3T + R, if small, the line must be pressed. (1) The lower die gap will cause the waste to warp upward, reducing the contact area with the inner surface of the die and reducing the frictional resistance, which will cause the waste to bounce back in the state of high-speed punching. depending on the machine model. bvseo-msg: BV SEO Content for this product did not include verbose reviews.. Machine Mart Ltd 211 Lower Parliament Street, Nottingham NG1 1GN. Check the hydraulic system oil level condition only by observing the level gauge, not by opening the plug or cleaning cap. The lower die of the roller cutting tools consists of the lower die seat and the roller wheel group (for the roller cutting tools of the lower die of the roller processing also includes the control wheel). The upper and lower cavities of the cylinder make the piston rod drive the ram up and down in reciprocal motion, impacting the mold for punching. sliding fence drill-bit guide drill-bit guide. text-align: center; Frames made with dowelled butt joints are surprisingly strong. (4) The required discharge force is greater than the spring force. Equivalent to a pair of the same friction payment, it is very easy to wear the edge or produce accumulation of scabbards. Too high or too low temperature will affect the normal operation of the machine tools. Secondly, because the stroke of the striking head can not be controlled, it is difficult to control when forming and stamping. Organize worksites and workpieces. (5) If the two shapes are close together (front, back, left and right), please be sure to explain it to us, otherwise there may be interference. Absolutely prohibit the use of twine, raw material tape, adhesive as sealing material, otherwise it will contaminate the system and may cause system failure!!! General system operation 1000 hours or intermittent operation half a year requires replacement of the cartridge. Even if the waste is punched into the die, if stranded on top of the previous waste, it is easy to bounce out of the die due to vibration, the formation of waste bounce, so it must be scientifically selected mold. (1) The machine has not been used for a long time, there is rust in the cylinder. Perform the lubrication and maintenance of the equipment in strict accordance with the lubrication part of each shift, and do not start the machine without daily maintenance. The other causes mentioned above, such as unstable air pressure, can be addressed on a case-by-case basis. The fastest processing speed is in G36 mode when punching mesh. .secure-payment .container { Secondly, the power consumption is large, which is the largest power consumption in all kinds of CNC turret punches. The role of the hydraulic station is to provide a constant source of oil pressure to the punch. Generally speaking, when three rows are distributed, the punch is often made of a movable type, i.e., the punch needs to punch one row of dies, and the punch is moved over the corresponding row of dies by a moving device. The upper and lower turntables are driven by a digital AC servo motor, which is coupled to the input of the gearbox via a flexible coupling, and the output of the gearbox is driven up and down the turntable via a chain and gear. When machining aluminum, the gap should be 15-20% of the thickness of the material. The biggest advantage of this structure is that the inertia of the feed is small and can be driven by a servomotor with low torque. Allow accurate cuts of 45, 90 or 45 with a mitre box. If the minimum scrap is too small, the scrap is not easy to be punched off when the mold gap is large. Stamping solenoid valve damaged; spool pulling, inflexible seizure. Shaping time for a salad knife (including pre-holes) is about 1.3 seconds; Forming time for a letter mold is about 0.7 seconds; The forming time for a normal bale is about 3 seconds; for a taller bale it is about 4 seconds; Due to the special molding conditions, it takes about 5 seconds to complete; The NCT has a step of about 1mm when punching the reinforcement, so the speed of punching the reinforcement is very slow and this method is not suitable for mass production. (The pressure should be adjustable, connected to the machine, and in areas where the air is very humid, dry with air desiccant). Check the drive, connection, lubrication and other parts of the machine tool and the protection and safety devices are normal, the mold screw must be solid, not move. With a normal tool, you can use the M command to draw or punch a convex, but only in the downward direction. Verify that the program can be run correctly before loading and stamping. Some essential woodworking tools are planers and honing guides. (2) Adjust the sensing distance by tightening the bracket. Adjustments should be made carefully, and each adjustment should not exceed 0.10mm, otherwise the mold will be damaged or even damage the machine. Simply clamp the jig in position and use an electric or cordless drill with the correct sized drill bit to accurately position the required diameter hole. It is done through the oil misters, the oil supply is adjustable. Observe the direction of rotation of the upper dead center cam, and be sure to hold down the main valve button. When long body parts are punched or improperly made, safety racks or other safety measures shall be provided to prevent excavation. If the workpiece is smaller than the minimum, only one jaw grip can be considered. (1) Poor verticality or straightness of the sheet itself. If the X direction is beyond this range, it can be adjusted using the automatic gripper command G27, in the form of G27X movement amount. The punch is mainly used to strike the die, it is the source of power for the punch and its own power is done by the hydraulic station. After a couple of trial holes I was able to knock up the base of a unit in no time at all. Rated working pressure 0.55Mpa or more, storage flow rate: 1.2m3/minute or more, the gas pipe connected to the machine requires pressure resistance of 10 kg or more, the inner diameter of the pipe is about 25 mm high-pressure explosion-proof pipe. Download our app - the easiest and quickest way to shop! If the upper and lower turntable positions are misaligned due to clips, etc., a synchronous adjustment must be made according to the following steps. (8) The adherent layer of the sheet is also an important factor in the rebound of the waste. At present, the more common CNC turret punching machine dies have two kinds: long structure dies and short structure dies. In addition, there are two types of sheet supports on the table, one is a universal transfer ball (steel ball) and the other is a hard brush. (5) The feeding speed is too fast and the spring is not responsive or sensitive. Set includes an aluminium jig with pre aligned holes, clamps and depth stops. The stamping stroke is fixed, so the stamping speed can not be improved. So for the case of a too large gap, we must choose the appropriate gap, sometimes even consider using a smaller gap. 1Implementation of the installation process, 2Maintenance of hydraulic systems General principles. There are two types of notches for the front die cutter, as shown in Figure 3 and Figure 4. (3) If the machine is in a power-off state, the punch is not on the dead point, and just stopped in the rotating position, the upper and lower modes are not at the same angle, it is impossible to achieve the adjustment of the start-up state, it is necessary to adjust manually. In this case, if oiled, it will make the rust more easily stained, so when punching this material, instead, wipe the oil clean, break down the mold every half month, wash it with gasoline and reassemble it, so that it can be satisfactorily processed. As regards reliability I think the sturdy plastic should survive pretty well and I see from the info on the packet you can get replacement bushes should they get too sloppy. After a single adjustment, make a step-stroke adjustment. (1) The upper and lower dials are misaligned. Stop in time at the end of the work, cut the power, wipe the machine and clean the environment. The appropriate toughness is beneficial to the punching, it can inhibit the degree of deformation when punching; Too much toughness can cause severe bounce after punching, which in turn affects accuracy. In the absence of any alarm on the machine, CNC executes a program, according to the program instructions, X and Y axes with the steel plate movement to the punch, T disk will move the mold required in the program to the punch head, the hydraulic punch head executes the strike to the mold and completes a stamping, then X and Y axes move one more position, the punch executes another stamping, and so on and so forth, only until a program is fully executed, back to the feeding position. In this case, it is necessary to jump up a station or use heavy-duty spring. Your email address will not be published. The situation in the danger zone is shown in the diagram: In the first case, the jaws are located between the upper and lower moulds and the punch will damage the jaws; In the second case, although the jaws will not be damaged, the material will be deformed because it is in a different plane. These two structures of the mold both need to be installed on the upper turntable support spring, so that the mold can be reset in time after the punch. Mechanical main drive principle (300 in ET-300 refers to a nominal force of 300KN). Count programming according to the parts diagram and the process content, and then according to the instruction code and program format specified by the used CNC system; (mainly manual code editing and computer programming software). This kind of CNC turret punch drives the flywheel to rotate through the main motor, uses the inertia of the flywheel for stamping, and is controlled by the clutch. The function of each switch in the upper dead point section and its adjustment method. The range of work before and after the jaws is expanded as shown in the figure below. If the mold is sharpened more than 4 mm, it is necessary to consider changing the core of the mold, otherwise the convex mold will have less and less penetration into the concave mold. }. Clean up the site and keep the worksite tidy. The movable tablerefers to the feeding table that moves with the sheet during the work. Due to the softness of aluminum, if the upper and lower die gaps are slightly large, it is easy to produce burrs, especially when punching the mesh holes, it can be clearly seen. sliding fence drill-bit guide drill-bit guide head. To develop, on the basis of the process analysis, all process information required for processing e.g. Treatment with filler in the center position less than 10 mm from the edge. (T indicates material thickness). But too much lubricating oil often stays in the upper die end surface, the strike during punching and cutting is easy to make the upper die end surface and waste to produce vacuum adsorption between the formation of slag, ie: waste rebound. Operators shall not leave the machine or perform other work while the equipment is in operation. A single salad hole filling with a large diameter as the base of both sides of the offset 5mm, this is the long side (assuming the length is A), then the other side for A/2+1 select SQA+1 square knife punch. The service life of the oil is related to its own condition, working temperature, the amount of oil in the tank, the service time, etc. According to the original conditions such as part drawing and process requirements, compile the part CNC machining program, and input to the CNC machines digital control system to control the relative movement of the tool and workpiece in the CNC turret punch press, so as to complete the machining of parts. Also, wipe down the area around the die before putting it into the die. (6) The mold adjustment method is shown in the following figure. It is mainly used for the storage and recall of dies, and when the tool selection program is performed, the corresponding dies are transferred under the punch. If the pressure is lowered, the air pressure must be brought back to zero, the adjusting handle must be dialed out and adjusted counterclockwise until the rotation does not move. The length direction is the same, but the width direction is different from the width of a die. For example, the lower die for 2mm plate cannot be processed for 3mm plate, nor for 1mm plate, otherwise it will increase the wear and even break the die. (7) It is inevitable that there is a little bit of lubricant or anti-rust oil on the bottom of the upper mold or sheet, but never so much as to form a fluid. In this case, the edge must be sharpened immediately and demagnetized with a demagnetizer after sharpening. The clearance of the lower die is determined according to the thickness of the processed plate. Drills and drills stops are not included with this product. Turn the adjustment handle clockwise to the specified pressure and press the adjustment handle. And a dedicated maintenance staff was set up to carry out scheduled maintenance. The power supply is put into position, well-grounded (three power lines, one grounding line, wire diameter10mm2or more), the voltage range is required to 380+10%-5%, if the voltage is unstable, add a regulator power supply; if there is leakage protection, add an isolation transformer, the total power above 50KVA. For a rust-free, non-scaling material, oil the mold with light machine oil. The solution is to change the position of the jaws, change the tool position, change the size of the mold or design a substitute jaw. 3.CNC turret punch driven by servo motor, Estimated machining time for CNC turret punch, Maintenance and repair of CNC turret presses, Problems that should be noted in the use of CNC turret punch press, CNC turret punching machine operation specification, Mechanical main drive turret punch (mechanical series), Maintenance and repair of hydraulic systems (hydraulic series), Die clearance for mild steel, stainless steel, aluminum, copper and brass, 36 Types of Thermomechanical TreatmentProcess, Top 10 Shearing Machine Manufacturers in China (2022 Updated), Global Top 10 Press Brake Manufacturers (2022 Updated), Top 20 Laser Cutting Machine Manufacturers in 2022, Pump Control Technology: ItBrings Performance Upgrade to Hydraulic Press Brake, 13 Types of Springs: Performance And Application. Enter your email below to receive immediate notification when this item is back in stock. Shop our wide selection of woodworking tools at Toolstation, including glue guns, chisels and planers. The gap between the convex and concave dies expressed as the total difference. Two points to note with this method: first, there must be upper and lower die available, and second, the forming depth must not exceed a material thickness. Wolfcraft Dowelmaster Dowelling Jig (4643X). The NCT tools are divided into five classes A, B, C, D and E according to their size, with the smallest class A and the largest class E. Each level of cutter corresponds to the position of the cutter on the turntable. This feature extends the machines range in the X-axis direction (repositioning can only be done in the X-axis). The mold should be tight and firm, the upper and lower molds should be correct, the position should be correct, the machine should be moved by hand for test punching (empty car) to ensure that the mold is in good working condition. It is recommended to use 1075 filtration device to refuel the hydraulic system. Drive components such as airlines, oil lines, screws, rails and gears are regularly cleaned and recorded. The 5-piece chisel set contains 6, 10, 13, 19 & 25mm chisels. If the size and distance of the holes are not the same, we will negotiate with the customer within the tolerance to change the size of the holes to the same, so that we can open the die for mass production (e.g., NCT multi-punching). The gripper is generally connected to the drag plate on the crossbar via a T-slot or dovetail slot. width: 75px; However, this should be done with full consideration of the impact of the burr facing the part. } .secure-payment .container { (1) Due to air pressure causes the dead point is not in place, in a manual way, start the motor, turntable pin into, press the dead point adjustment key F1, until the alarm disappears. Prohibit the use of strong force on the hydraulic system to avoid subjecting the piping system and components to lateral force or internal stress, and be sure to protect the piping system. process route, process requirements, tool trajectory, displacement, and auxiliary functions and to fill in process cards andtechniquecards. The stability of air pressure is one of the prerequisites for machine work, and unstable or insufficient pressure can cause various problems. Nowadays, most factory-made furniture incorporates dowel joints, even for chair rails which must be capable of resisting prolonged and considerable strain. The motor must be disconnected and effectively protected during the cleaning process. The switch is set to start at 40C. Even with an extremely complex workpiece with 30 knives, the changeover time should not exceed 15 seconds. Electrical control failures, mainly the failure of the optocoupler controlling the punch valve. The life of the molds using these two materials is generally 200,000 to 300,000 times. Required fields are marked *. Use the Milwaukee Inkzall Fine Point marker for writing on dusty, wet and oily surfaces, or alternatively, use a classic builders marker from Markal which is more economical and longer lasting than wax crayons. (3) The repositioning cylinder is controlled by two five-way solenoid valves, and the cylinder is fixed on the bracket connected with the bed. Process analysis according to the requirements of the drawings of the parts, including the analysis of the structural processability of the parts, rational analysis of the material and design accuracy, approximate process steps, etc. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); With over 20 years of experience in metalworking and mechanical engineering, we're dedicated to providing top edge machinery, expert consultation, quality customer service to you so as to help you get more out of your metal! CNC turret punching machine is a flexible automatic machine that can adapt to frequent changes in the product, the machining process requires a variety of operations and steps and the relative displacement between the tool and the workpiece are represented by digital code, through the control media (such as paper tape or disk) to send digital information into the special or general computer, the computer processing and operation of the input information, to issue a variety of instructions to control the machines servo system or other executive components so that the machine automatically processed the required parts or products. If misplaced, it can break the mold and even damage the machine. (2) The slag falls on the lower turntable, causing a hidden danger of feeding, and the plates can be scratched or even smashed. Shut off the oil pump, turn off the main power of the machine, The communication cable must be plugged in when the machine tools computer power failure, Let down the machine guard, close the movable table, put away the tools. (6) When the upper and lower molds or the upper and lower molds are heavily eccentric, excessive burrs on one side can also cause the waste to be carried out of the lower mold with the movement of the sheet. The machine is strictly manned and absolutely not allowed to be operated by uncertified personnel. There are two turntables for CNC turret punching machines, called upper turntable and lower turntable. The adjusted chain should have a drop of 6-13 mm. To avoid external leakage, tighten all fittings and install hoses correctly to avoid scuffing, bumping and twisting of hoses. Drill both holes. The Y-axis drive is basically the same as the X-axis, but also consists of ball screws, linear guides and couplings, servo motors. 22-24 Boulevard Royal L-2449, Luxembourg. 1)Overcome by using the photoelectric induction installed by NCT itself. This is because when the machine tool driven by the servo motor does not punch, the main motor is in a static state and does not consume power. The origin pin is in its original position (i.e., dropped) throughout the job. The lubrication nozzle in the bearing housing is used to lubricate the screw support bearing at regular intervals, with a lubrication cycle of once a week. The maximum distance for holes from the edge of the board is 15mm, so you can use a thicker board, but don't expect the holes to be in the middle. Saw each component to length and trim the ends of the rail square as described for making a square-ended butt joint (see page 18). Adjustable drill-bit guides and side fences position the dowel holes. Punching a square hole causes the edge to be turned up, the larger the hole the more obvious the turning of the edge, in this case the LASER secondary cutting is often considered (the customer can also be consulted on whether this distortion is acceptable). Each machining method has a specific NC program instruction. When more than two people are working together, the person responsible for carrying (pedaling) the gate must pay attention to the movement of the feeder and it is strictly forbidden to carry (pedal) the gate while taking the parts. The operator must be familiar with the construction and performance of the machine. In terms of ownership, there are more than 20000 sets of CNC presses in the United States and nearly 20000 sets in Japan. Turn on the air machine to drain the moisture from the airway. Regularly check the working conditions of the hydraulic station, return oil pressure pointer to the yellow zone to clean, replace the oil filter, to the red zone to replace the hydraulic oil (VT-300 hydraulic system type machine tool). Remove both end fences of a dowelling jig when boring holes in the edge of a wide board. Failure Analysis: There are several main reasons for the instability of the upper dead spot. The following table shows the dimensions of the tooling and tool mounting position: 1) Introduction of turret punch press molds. This kind of machine tool has the advantages of simple structure, low product price and stable performance. The positioning block is directly connected to the cylinder rod, and the lifting of the positioning block can be controlled by manually controlling the operation button on the crossmember shroud during loading. Note: New oil and clean oil are two completely different concepts and should not be confused. (2) Tighten the bolts of the support seat and fuselage coupling to eliminate displacement of the sheet after the clamp is released. The rolling rib and rolling cutting die can be processed like the hydraulic punch, and the stamping noise can achieve the ideal effect. Machine Mart 2022, All rights reserved. The principle of the hydraulic main drive is that the hydraulic oil supplied by the hydraulic system is fed into the fluid by the action of an electromagnetic reversing valve. The following categories are commonly used. (2) when the implementation of the program, there is an alarm, the machine tool is in a state of maintenance, in the case of not pressing the reset button, directly switch to manual mode, press the dead point adjustment key F1, until the alarm disappears; and then switch to automatic mode, press the cycle start, the machine will then interrupt the implementation of the program. By turning the adjustment screw counterclockwise, the oil supply to the oil misters increases, and by turning the adjustment screw clockwise, the oil supply to the oil misters decreases. (3) Tighten the coupling screw at the tooth plate of the jaws. A gripper is a manipulator used to hold sheet material, usually powered by compressed air or hydraulic oil. Recommended hydraulic fluid type: Mobil DTE-25VG46 anti-wear hydraulic fluid. (2) After a certain number of sharpened die impacts, the edges of the cutting edge become white and rounded like frost, which is the result of hardening and passivation of the process.
