Description

Technical Field

[0001] This invention relates to the field of punching technology for clutch parts, specifically to an automotive clutch processing device and processing method. Background Technology

[0002] The automotive clutch is a core component of the automotive powertrain system, located between the engine and the transmission. Its main function is to smoothly engage and disengage engine power, ensuring smooth vehicle starts and gear shifts, while also buffering transmission overload and protecting transmission components. The clutch pressure plate is the core load-bearing and clamping component of the clutch, and its machining accuracy directly determines the clutch's transmission stability and service life. During production, the clutch pressure plate must undergo punching. The machined holes are primarily used for component assembly and positioning, bolt tightening, optimizing heat dissipation, reducing overall weight, and facilitating the installation of internal clutch components such as shift forks and springs. This is a crucial step in pressure plate machining. Therefore, stringent requirements are placed on the hole diameter accuracy, hole coaxiality, and machining consistency. Currently, automotive clutch pressure plates need to be produced to fit multiple vehicle models and specifications, resulting in varying hole diameters and radial punching positions. Traditional clutch punching equipment has several shortcomings in practical use. Summary of the Invention

[0003] The purpose of this invention is to provide an automotive clutch processing device and processing method to solve the problems mentioned in the background art.

[0004] The objective of this invention can be achieved through the following technical solutions: An automotive clutch processing device includes a base plate, a side plate fixedly mounted on one side of the base plate, a rotating column rotatably mounted on the side plate located in the middle of the base plate, a support plate fixedly mounted on the rotating column, a circumferentially arranged sub-bracket arranged on the outer side of the support plate, a cross groove opened in the middle of the sub-bracket, a cross plate slidably mounted in the middle of the cross groove, and a punch slidably mounted in the middle of the cross plate.

[0007] Preferably, an air cylinder is also fixedly installed on one side of the fixed cylinder, a piston rod is slidably installed in the middle of the air cylinder, an opening is provided on one side of the bottom plate, the opening is located outside the air cylinder and slides, an extension plate is fixedly installed on the top of the piston rod perpendicular to its axis, an electric push plate is fixedly installed on one side of the center plate, an electric push plate is fixedly installed on one side of the extension plate, a sleeve plate is fixedly installed on the telescopic end of the electric push plate, and an air blowing pipe for cooling the punch located below the fixed cylinder is fixedly installed at the lower part of the air cylinder.

[0008] Preferably, the control unit includes a rotating ring located on the upper part of the support plate and connected to it by an electric slip ring. The outer edge of the rotating ring is provided with multiple ear plates in a circumferential direction. The upper end face of the ear plate is connected to a push-pull plate, and the end of the push-pull plate away from the ear plate is hinged to its corresponding cross plate.

[0009] Preferably, the shifting module further includes a corresponding disk fixedly connected to the rotating column and located above the support disk and coaxial with it. The corresponding disk has conversion slots that correspond one-to-one with multiple punches, and a rotating rod connected to the side plate by a motor. The bottom of the rotating rod is fixedly installed with a turntable located below the corresponding disk, and the upper end face of the turntable is fixedly installed with a wave column that moves multiple conversion slots to rotate and shift positions.

[0010] Preferably, two symmetrical conveyor frames are fixedly installed on the upper surface of the base plate. Each of the two conveyor frames has a conveying groove on the side close to each other. Multiple sets of moving parts are slidably installed in the conveying groove via electric sliders. Each set of moving parts has symmetrically arranged slide rods slidably installed on it. Each of the two slide rods has a symmetrical clamping plate on the side close to each other. A rotating seat is provided in the clamping plate. A spring is also provided on the outside of the slide rod, and the spring is located between the moving part and the clamping plate to abut against it.

[0011] Preferably, a vertical plate is fixedly installed on the upper part of the base plate, a top plate is fixedly installed on the upper end face of the vertical plate, an electric push rod is rotatably installed in the middle of the top plate, a stabilizing plate is fixedly installed on the telescopic end of the electric push rod, multiple telescopic plates are fixedly installed on the outer edge of the stabilizing plate, a collar is fixedly installed on the telescopic plate away from the stabilizing plate, a lower cylinder adapted to the corresponding punch is installed in the middle of the multiple collars, a push rod is slidably installed on the bottom of the lower cylinder, a push plate is fixedly installed on the upper end of the push rod, and a spring is also provided on the outside of the lower cylinder located inside the lower cylinder.

[0012] A lower rod is fixedly installed at the bottom of the support plate. Both the lower rod and the electric push rod are equipped with sprockets at their bottoms, and a chain is installed between the two sprockets.

[0013] Another object of the present invention is to provide a processing method for an automotive clutch processing device, comprising the following steps: S1: Punching preparation: The pressure plates are placed on the corresponding clamping plates and clamped. Then, the clutch pressure plate to be punched is transported to the bottom of the fixed cylinder. The shifting module is opened to allow the required punch to slide along the trajectory in the arc groove to the top of the required punching pressure plate. The control unit is opened to adjust the distance of multiple punches along the axis of the rotating column, thereby moving the punch directly above the pressure plate to a certain position to meet the punching requirements of different radial positions of the pressure plate. When the shifting module is opened to select the required punch, the rotation of the lower rod can also drive the electric push rod to rotate synchronously through the sprocket and chain, so that the lower cylinder that matches the selected punch can rotate synchronously to the bottom of the required punching position, so as to support the punching position and push out the waste.

[0014] S2: Punching operation: During the punching operation, the cylinder is activated and pushed downwards. As the cylinder pushes down, it moves downwards through the center plate in the center groove, causing the bottom rod to move the bottom plate downwards. As the bottom plate moves downwards, it drives the T-shaped plate and the arc plate to press down, thereby pressing the selected punch down within the cross plate. When the punch is pressing down, it punches the pressure plate. When the punch is punching the pressure plate, it enters the lower cylinder after squeezing the push plate. When the punch moves upwards, the push plate loses the downward pressure of the punch, and the push plate can then push out the waste generated during punching from the lower cylinder under the action of the spring.

[0015] The beneficial effects of this invention are: 1. This invention uses a motor to drive a rotating rod and a toggle column to rotate the corresponding disc and rotating column, thereby completing the switching of different specifications of punches. The lower rod below the support disc drives the electric push rod to rotate synchronously with the help of a sprocket and chain, so that the lower cylinder and the punch rotate synchronously one-to-one. The upper and lower dies are automatically aligned by relying on pure mechanical transmission. When changing the punching specifications, there is no need to manually calibrate the coaxiality, which greatly reduces the tool changing and debugging time and effectively avoids failures such as hole position displacement and punch breakage caused by die misalignment.

[0016] 2. This invention uses a rotating ring to pull a push-pull plate, causing the cross plate to slide radially along the cross groove, freely changing the radial position of the punch. This adapts to punching at different radii on the clutch pressure plate. After the punch position is adjusted, the T-shaped plate in the T-groove at the bottom of the bottom plate slides laterally, and the arc groove always fits the top of the punch. The radial adjustment mechanism and the vertical punching module work together, and the pressure head can automatically follow the displacement of the punch, always maintaining vertical downward pressure without force deviation. No secondary calibration is required after the position is adjusted, improving processing and debugging efficiency.

[0017] 3. When the cylinder punches downwards, the center plate drives the extension plate downwards. The mechanical linkage triggers the air cylinder to compress air. The blower sprays cold air the moment the punch contacts the workpiece, simultaneously cooling the punching area, reducing high-temperature wear on the punch, ensuring the punching quality of the workpiece, and avoiding energy waste caused by continuous empty blowing. After punching is completed, the punch is lifted to release the pressure, and the spring in the lower cylinder rebounds to push out the waste material. The spring on the outside of the punch synchronously drives the punch to automatically rebound and reset. The waste material discharge and punch reset are automatically completed with the punching process, preventing waste material blockage and ensuring long-term continuous and stable operation of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9As shown, the present invention is an automotive clutch processing device, including a base plate 1, a side plate 10 fixedly installed on one side of the base plate 1, a rotating column 2 located in the middle of the base plate 1 rotatably installed on the side plate 10, a support plate 21 fixedly installed on the rotating column 2, a circumferentially arranged sub-branch 22 arranged on the outer side of the support plate 21, a cross groove 23 opened in the middle of the sub-branch 22, a cross plate 24 slidably installed in the middle of the cross groove 23, a punch 25 slidably installed in the middle of the cross plate 24, multiple circumferentially arranged punches 25 of different specifications to meet different punching requirements, a spring sleeved on the outside of the punches 25, an adjustment part for adjusting the spacing between multiple cross plates 24 on the upper end face of the support plate 21, a shifting module for shifting multiple punches 25 on the rotating column 2, a support plate 3 fixedly installed on the side plate 10, a punching module for moving the punches 25 below it to achieve punching operation on the support plate 3.

[0023] The punching module includes a fixed cylinder 31 mounted on a support plate 3. A central groove 311 is provided on the fixed cylinder 31. A central plate 312 is slidably installed in the central groove 311. A cylinder 313 with its telescopic end connected to the central plate 312 is fixedly installed on the top of the fixed cylinder 31. A bottom rod 314 that passes through and slides on the support plate 3 is fixedly installed on the lower end face of the central plate 312. A bottom plate 33 is also fixedly installed on the bottom of the bottom rod 314. An adaptive part is provided below the bottom plate 33 to follow the punch 25 below it to move laterally when the spacing of multiple punches 25 is adjusted.

[0024] The cylinder 313 presses down, driving the punch 25 to pierce the workpiece downwards. The punch 25 squeezes the push plate 562 and compresses the spring inside the lower cylinder 56, causing the push rod 561 to retract and create punching space. When the cylinder 313 returns upwards, the punch 25 lifts up, releasing the pressure on the push plate 562. The compressed spring inside the lower cylinder 56 immediately rebounds, driving the push plate 562 to push the waste material out of the hole. The punching action and the waste removal action are seamlessly connected. After each hole is processed, the waste material is immediately pushed out of the cylinder, preventing waste material from accumulating inside the lower cylinder 56. This effectively prevents waste material from clogging and causing subsequent punching deformation and needle breakage, ensuring long-term continuous and stable operation of the equipment.

[0025] After a single punching operation, cylinder 313 lifts upwards to release the downward pressure, while the cross plate 24 remains stationary. The spring fitted around the outside of the punch 25 quickly rebounds after losing downward pressure, pulling the punch 25 back to its initial height. Thanks to the spring-reset structure, the punch 25 can quickly disengage from the workpiece hole without getting stuck inside. The reset action is automatically completed following the punching force release action. The entire punching-punching-lifting-reset cycle is smooth and without jamming, improving the single punching cycle time. The shifting module drive motor drives the rotating rod 342 and the turntable 343 to rotate. The actuating column 344 actuates the conversion slot 341 on the corresponding plate 34, causing the rotating column 2 and the support plate 21 to rotate as a whole, which can rotate punches 25 of different specifications to the punching station in sequence. The lower rod 211 at the bottom of the support plate 21 is linked to the electric push rod 52 through the sprocket 6 and chain 61, which drives the stabilizing plate 53, the telescopic plate 54 and the collar 55 to rotate synchronously, so that the lower cylinder 56 matching the current punch 25 can be accurately rotated to the bottom of the workpiece, realizing the synchronous shifting of punch 25 and lower cylinder 56, ensuring that the upper and lower dies always correspond one-to-one, without the need to adjust the lower die position separately, and greatly shortening the tool change and debugging time.

[0026] The rotating ring 26 drives the push-pull plate 28 to pull the cross plate 24 radially along the cross groove 23, completing the radial position adjustment of the punch 25. At the same time, the T-slot 331 at the lower end of the bottom plate 33 and the T-plate 332 form a transverse sliding pair. The arc plate 333 moves laterally synchronously with the punch 25, and the arc groove 334 always wraps around the top of the punch 25 at the current station. When the punching module is pressing down, the cylinder 313 drives the center plate 312 and the bottom rod 314 to drive the bottom plate 33 to press down vertically. The adaptive part can automatically align with the radial position that the punch 25 has been adjusted. The radial position adjustment mechanism and the vertical punching mechanism are independent of each other but cooperate with each other. After the punch position is adjusted, there is no need to recalibrate the pressure head. Radial adjustment and punching operations can be performed continuously, greatly shortening the station debugging time.

[0027] The adaptive part includes a T-shaped groove 331 formed on the lower end face of the bottom plate 33. A T-shaped plate 332 is slidably installed in the T-shaped groove 331. An arc-shaped plate 333 is fixedly installed on the lower end face of the T-shaped plate 332. An arc-shaped groove 334 is formed on the lower end face of the arc-shaped plate 333. When the multiple punches 25 rotate and change position, one punch 25 is always located in the arc-shaped groove 334.

[0028] In the control unit, the rotating ring 26 rotates above the support plate 21 by relying on the electric slip ring, which pulls multiple push-pull plates 28 to drive the cross plate 24 to slide radially along the cross groove 23, and simultaneously adjusts the circumferential spacing between all the cross plates 24, thereby driving the punch 25 to change its radial position, which can meet the punching processing of different radius positions of the clutch pressure plate.

[0029] When the punch 25 undergoes radial displacement, the T-shaped plate 332 in the T-slot 331 at the lower end of the bottom plate 33 can slide laterally, and the arc plate 333 shifts laterally synchronously with the punch 25. The arc groove 334 always covers the top of the punch 25 at the current station. During the pressing process of the punching module, the arc groove 334 can adaptively follow the radial position change of the punch 25 and always apply downward pressure to the punch 25. It will not cause the punch head to be misaligned or the force to be biased due to the radial displacement of the punch 25, thus ensuring that the pressure is vertically downward.

[0030] An air cylinder 32 is also fixedly installed on one side of the fixed cylinder 31. A piston rod 321 is slidably installed in the middle of the air cylinder 32. A through-hole 330 is provided on one side of the bottom plate 33. The through-hole 330 is located outside the air cylinder 32 and slides. A 322 perpendicular to its axis is fixedly installed on the top of the piston rod 321. An extension plate 323 is fixedly installed on one side of the center plate 312. An electric push plate 324 is fixedly installed on one side of the extension plate 323. A sleeve plate 325 is fixedly installed on the telescopic end of the electric push plate 324 and is sleeved outside the 322. A blower pipe 326 for cooling the punch 25 located below the fixed cylinder 31 is fixedly installed on the lower part of the air cylinder 32.

[0031] When the cylinder 313 is pressed down, the extension plate 323 moves down synchronously with the center plate 312. The electric push plate 324 drives the sleeve plate 325 to press down the push rod 322, pushing the piston rod 321 to move into the air cylinder 32, compressing the air inside the air cylinder 32. The high-pressure airflow is sprayed out from the blow pipe 326, precisely aligning with the punch 25 and the punching position of the clutch pressure plate at the work station. When the high-speed punching friction of punch 25 generates high temperature, continuous cold air can quickly cool down the cutting edge of punch 25 and the workpiece processing area, reduce high-temperature wear of punch 25, avoid high-temperature annealing and enlarged burrs at the punching position of the workpiece, extend the service life of punch, and stabilize the punching processing quality.

[0032] During the downward movement of the center plate 312, the integrally connected extension plate 323 moves downward synchronously. The electric push plate 324 drives the sleeve plate 325 to press down the top rod 322, pushing the piston rod 321 to compress the air inside the air cylinder 32. The high-pressure airflow is then sprayed into the punching area through the blower pipe 326. The entire air supply action is triggered entirely by the downward punching action of the cylinder 313. The two are mechanically linked, and no additional independent timing controller is required. At the moment the punch 25 contacts the workpiece and begins to rub and punch, cold air is sprayed out synchronously. When the punch rises and returns, the piston rod 321 resets and stops supplying air. The cooling airflow is precisely synchronized with the punching action, which not only ensures continuous cooling of the high-temperature punching section but also avoids energy waste caused by continuous empty blowing of the air source.

[0033] The control unit includes a rotating ring 26 located on the upper part of the support plate 21 and connected to it by an electric slip ring. Multiple ear plates 27 are provided around the outer edge of the rotating ring 26. A push-pull plate 28 is connected to the upper end of the ear plate 27. The end of the push-pull plate 28 away from the ear plate 27 is hinged to its corresponding cross plate 24.

[0034] The shifting module also includes a corresponding disk 34 fixedly connected to the rotating column 2 and located above the support disk 21 and coaxial with it. The corresponding disk 34 has a conversion slot 341 that corresponds to a plurality of punches 25 one by one, and a rotating rod 342 connected to the side plate 10 by a motor. The bottom of the rotating rod 342 is fixedly installed with a turntable 343 located below the corresponding disk 34. The upper end face of the turntable 343 is fixedly installed with a wave column 344 that moves the plurality of conversion slots 341 to rotate and shift positions.

[0035] The motor drives the rotating rod 342, turntable 343, and actuating column 344 to move the corresponding disk 34, causing the rotating column 2 and support disk 21 to rotate, thus completing the switching of different specifications of punches 25. The lower rod 211 at the bottom of the support disk 21 rotates synchronously with the rotating column 2, and the electric push rod 52 rotates coaxially with the sprocket 6 and chain 61, so that the lower cylinder 56 changes position synchronously with the corresponding punch 25. The upper die punch and the lower die lower cylinder 56 are rotated synchronously one-to-one by pure mechanical chain transmission. Each time the punching specification is changed, the lower die support position is automatically aligned, eliminating the need for manual recalibration of the coaxiality of the upper and lower dies and preventing the problems of hole misalignment and punch breakage caused by misalignment of the upper and lower dies.

[0036] Two symmetrical conveyor frames 4 are fixedly installed on the upper surface of the base plate 1. Each of the two conveyor frames 4 has a conveying groove 41 on the side close to each other. Multiple sets of moving parts 42 are slidably installed in the conveying groove 41 by electric sliders. Each set of moving parts 42 has symmetrically arranged slide rods 43 slidably installed on it. Each of the two slide rods 43 has a symmetrical clamping plate 44 on the side close to each other. A rotating seat is provided in the clamping plate 44. A spring is also provided on the outside of the slide rod 43, and the spring is located between the moving part 42 and the clamping plate 44 to abut against each other.

[0037] Electric sliders on two sets of conveyor frames 4 drive moving parts 42 to horizontally convey workpieces along conveyor troughs 41. External springs on slide rods 43 push the clamping plates 44 on both sides to come closer together, achieving elastic clamping of the clutch pressure plate. The clamping plates 44 have built-in rotating seats, and the angle can be slightly adjusted after the workpiece is clamped. Spring buffering can avoid damage to the workpiece surface caused by rigid clamping. Multiple sets of workpieces to be processed can be continuously conveyed to realize continuous feeding of the production line and complete batch punching processing without interruption.

[0038] The electric slider on the conveyor frame 4 drives the moving part 42 to feed along the conveyor groove 41. The spring on the outside of the slide rod 43 continuously presses against the clamping plate 44, forming a flexible clamp on the clutch pressure plate. The rotating seat inside the clamping plate 44 allows for small-angle fine adjustment of the workpiece to ensure that the workpiece hole position reference is aligned. After the previous group of workpieces is punched, the conveying mechanism can quickly transport the next group of workpieces to be processed to the punching station. The clamping spring plays a buffering and protective role, which can ensure that the workpiece is firmly positioned and will not damage the surface of the clutch pressure plate blank. The feeding, clamping, conveying and punching processes are connected continuously, which is suitable for large-scale continuous automated production.

[0039] A vertical plate 5 is fixedly installed on the upper part of the base plate 1. A top plate 51 is fixedly installed on the upper end face of the vertical plate 5. An electric push rod 52 is rotatably installed in the middle of the top plate 51. A stabilizing plate 53 is fixedly installed at the telescopic end of the electric push rod 52. Multiple telescopic plates 54 are fixedly installed on the outer edge of the stabilizing plate 53. A collar 55 is fixedly installed on the telescopic plate 54 away from the stabilizing plate 53. A lower cylinder 56 adapted to the corresponding punch 25 is installed in the middle of the multiple collars 55. A push rod 561 is slidably installed at the bottom of the lower cylinder 56. A push plate 562 is fixedly installed at the upper end of the push rod 561. A spring located inside the lower cylinder 56 is also provided on the outside of the lower cylinder 56.

[0040] In the punching module, cylinder 313 pushes center plate 312 to slide downward along center groove 311 of fixed cylinder 31. Bottom rod 314 drives bottom plate 33 to move downward as a whole. Arc plate 333 presses down punch 25. Punch 25 compresses its outer spring downward to complete the punching of clutch pressure plate. After punch 25 penetrates the workpiece, it presses push rod 561 and push plate 562. Push rod 561 retracts into lower cylinder 56 to reserve space for punching.

[0041] The retraction of cylinder 313 causes punch 25 to lift upward, and the spring inside the lower cylinder 56 rebounds, pushing the pusher plate 562 upward, automatically pushing the punching waste from inside the lower cylinder 56 upward, realizing automatic discharge of punching waste without manual cleaning of waste, and continuous operation will not cause waste accumulation and blockage.

[0042] The punch 25 is externally fitted with a spring. After one punching operation is completed, when the lifting pressure of the cylinder 313 is released, the spring quickly pushes the punch 25 upward to reset. The cross plate 24 remains in the same position, and the punch 25 automatically springs back to the initial height, ready for the next punching operation. This ensures that the single punching operation cycle is smooth and there will be no situation where the punch gets stuck in the workpiece hole.

[0043] A lower rod 211 is fixedly installed at the bottom of the support plate 21. Both the lower rod 211 and the electric push rod 52 are equipped with sprockets 6 at their bottoms, and a chain 61 is installed between the two sprockets 6.

[0044] Another object of the present invention is to provide a processing method for an automotive clutch processing device, comprising the following steps: S1: Punching preparation: The pressure plates are placed on the corresponding clamping plates 44 and clamped. Then, the clutch pressure plate to be punched is transported to the bottom of the fixed cylinder 31. The required punch 25 is slid through the arc groove 334 to the top of the required punching pressure plate by opening the shifting module. The distance of multiple punches 25 along the axis of the rotating column 2 is adjusted by opening the control unit, so that the punch 25 directly above the pressure plate moves to a certain position to meet the punching requirements of different radial positions of the pressure plate. When the shifting module is opened to select the required punch 25, the lower rod 211 rotates and drives the electric push rod 52 to rotate synchronously through the sprocket 6 and chain 61, so that the lower cylinder 56 adapted to the selected punch 25 rotates synchronously to the bottom of the required punching position, so as to support the punching position and push out the waste.

[0045] S2: Punching operation: During the punching operation, the cylinder 313 is activated and pushed downwards. As the cylinder 313 pushes downwards, it moves down through the center plate 312 into the center groove 311, thereby causing the bottom rod 314 to drive the bottom plate 33 to move downwards. As the bottom plate 33 moves downwards, it drives the T-shaped plate 332 and the arc plate 333 to press down, thereby pressing the selected punch 25 down within the cross plate 24. When the punch 25 is pressing down, it performs a punching operation on the pressure plate. When the punch 25 is punching the pressure plate, it enters the lower cylinder 56 after squeezing the push plate 562. When the punch 25 moves upwards, the push plate 562 loses the downward pressure of the punch 25, and the push plate 562 can then push out the waste material generated during punching from the lower cylinder 56 under the action of the spring.

10. A processing method for an automotive clutch processing device, applied to the automotive clutch processing device according to claim 9, characterized in that, Includes the following steps: S1: Punching preparation: The pressure plates are placed on the corresponding clamping plates (44) and clamped. Then, the clutch pressure plate to be punched is transported to the bottom of the fixed cylinder (31). The required punch (25) is slid through the arc groove (334) to the top of the required punching pressure plate by opening the shifting module. The distance of multiple punches (25) is adjusted along the axis of the rotating column (2) by opening the control unit, so that the punch (25) directly above the pressure plate moves to a certain position to meet the punching requirements of different radial positions of the pressure plate. When the shifting module is opened to select the required punch (25), the lower rod (211) rotates through the sprocket (6) and chain (61) to drive the electric push rod (52) to rotate synchronously, so that the lower cylinder (56) that is compatible with the selected punch (25) rotates synchronously to the bottom of the required punching position, so as to support the punching position and push out the waste. S2: Punching operation: During the punching operation, the cylinder (313) is activated and pushed downward. When the cylinder (313) is pushed down, it moves down in the center groove (311) through the center plate (312), thereby causing the bottom rod (314) to drive the bottom plate (33) to move down.

When the punch (25) is pressing down, it punches the pressure plate. When the punch (25) is punching the pressure plate, it enters the lower cylinder (56) after squeezing the push plate (562). When the punch (25) moves up, the push plate (562) loses the downward pressure of the punch (25), and the push plate (562) can then push the waste generated during punching out of the lower cylinder (56) under the action of the spring.
