Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a stamping die spring material device. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Currently, the material ejection devices of existing stamping dies generally only have the function of lateral pushing. However, in many cases, the lower die of the stamping die is recessed. Direct lateral ejection is not conducive to pushing out the workpiece. The recessed lower die is also prone to jamming the workpiece, making it inconvenient for workers to remove the material.

[0003] A search revealed a stamping die ejector device with publication number CN210387320U, comprising: a lower die, an electromagnet, a connecting plate, a metal block, a push rod, a buffer block, a cover, a slide rail, a left groove bracket, a pin, a right groove bracket, a spring, and a slide rod. This technical solution also suffers from the aforementioned technical problem: direct lateral pushing. However, when dealing with some concave lower dies, direct lateral pushing of the workpiece cannot effectively push away the material, and direct pushing may also affect the forming quality of the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping die spring material device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stamping die springing device, comprising a lower die and an upper die disposed on the lower die, a spring plate disposed inside the lower die, a spring column fixedly connected to the top of the spring plate, a fixing plate disposed above the lower die, and a pusher plate connected to the side of the fixing plate by a spring. When the spring plate moves upward, the spring column will spring up the stamping workpiece, and the pusher plate will push the stamping workpiece to move laterally.

[0006] Optionally, a lifting plate is also included, which is disposed above the lower mold, and the upper mold is fixedly installed at the bottom of the lifting plate.

[0007] Optionally, the bottom of the lower mold is provided with a receiving groove, the spring plate is disposed inside the receiving groove, and a telescopic rod is fixedly connected to the bottom of the spring plate, and a spring is sleeved on the surface of the telescopic rod.

[0008] Optionally, guide frames are provided in the receiving groove and on the side of the lower mold. A rope is fixedly connected to the bottom of the spring plate. The end of the rope away from the spring plate passes through the two guide frames and is connected to a driving plate. A support beam is provided on the side of the lower mold, and the rope passes through the top of the support beam.

[0009] Optionally, a telescopic rod two is fixedly connected to the side of the fixed plate, and the end of the telescopic rod two away from the fixed plate is fixedly connected to the pusher plate, and the spring two is sleeved on the surface of the telescopic rod two.

[0010] Optionally, a second rope is fixedly connected to the side of the pusher plate, a second frame beam is provided on the side of the upper mold, and a moving strip is fixedly connected to the end of the second rope away from the pusher plate passing through the top of the second frame beam. An elastic plate is fixedly connected to the bottom of the moving strip, a locking block is fixedly connected to the side of the elastic plate, and a second driving plate is fixedly connected to the other side of the elastic plate.

[0011] Optionally, a bending frame is fixedly connected to the top of the lifting plate, and a moving plate is fixedly connected to one side of the bending frame.

[0012] Optionally, a vertical plate is fixedly connected to the bottom of the motion plate, and a pressure plate is connected to the bottom of the vertical plate via a telescopic rod. A spring is sleeved on the surface of the telescopic rod.

[0013] Optionally, a vertical plate two is fixedly connected to the bottom of the motion plate, and a pressure plate two is connected to the bottom of the vertical plate two through a telescopic rod four. A spring four is sleeved on the surface of the telescopic rod four.

[0014] Optionally, a connecting frame one is fixedly connected to the side of the spring plate, and a connecting frame two is connected to the connecting frame one via a connecting rod. A shaped frame is fixedly connected to the side of the connecting frame two, and a slider is slidably connected to the surface of the bending frame. A support frame is fixedly connected to the bottom of the slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the cooperation of a lower die, an upper die, a spring plate, a spring column, a fixing plate, a second spring, a push plate, a lifting plate, a receiving groove, a first telescopic rod, and a first spring, enables the stamping die to not only have vertical springing function but also horizontal springing function during use. The stamped workpiece will be bounced upward first and then pushed horizontally. In this way, whether the material is a flat lower die or a concave lower die, the springing function can be well performed. After stamping, the material can be automatically ejected without manual unloading, reducing the workload of the staff and making it convenient to use.

[0016] This invention, through the cooperation of a guide frame, a first rope, a first driving plate, a first frame beam, a second telescopic rod, a second rope, a second frame beam, a moving strip, an elastic plate, and a locking block, enables both the elastic plate and the push plate to have a pulling mechanism during use. Furthermore, the pulling mechanism extends to the outside of the lower and upper molds, and the protruding structural design facilitates operation.

[0017] This invention, through the coordinated operation of a bending frame, a moving plate, a vertical plate 1, a telescopic rod 3, a pressure plate 1, a spring 3, a vertical plate 2, a telescopic rod 4, a pressure plate 2, and a spring 4, enables the material ejector device to possess a driving mechanism. It reuses the lifting driving force of the lifting plate to pull the material ejector plate and the pusher plate to move. When the lifting plate moves upward and the downward pressure disappears, the material ejector plate and the pusher plate will work to eject the stamped workpiece, eliminating the need for manual operation and additional driving mechanisms. The force used is still the stamping force during the stamping process, making it convenient to use.

[0018] This invention utilizes the cooperation of connecting frame one, connecting rod, connecting frame two, irregular frame, slider, and support frame. During use, the upward movement and resetting tendency of the spring plate unlocks the push plate, creating a time difference between the movements of the spring plate and the push plate. After the spring plate moves upward, it first bounces the workpiece on the lower mold upward. When the workpiece is in position, that is, after the spring plate resets, the irregular frame pushes the locking block completely away from the fixed plate, thus unlocking the push plate and allowing it to move horizontally to push the workpiece. This structure realizes the transmission of structural components and the asynchronous operation of the structure, eliminating the need for additional electric drive equipment, saving costs, and making it convenient to use.

Detailed Implementation

[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] Example This technical solution is a stamping die spring device used in a stamping press. Therefore, in order to fully disclose the entire technical solution and to clarify the application scenario, the specification also discloses the conventional hydraulic frame.

[0023] Please see Figure 11-13A hydraulic frame includes a horizontally arranged base plate 41. Vertically extending support columns 42 are fixedly connected to the four corners of the top of the base plate 41. The tops of the four support columns 42 are fixedly connected to a horizontally arranged top plate 43. Two of the four support columns 42 have a sliding groove 52. The top plate 43 forms a mounting surface, on which a hydraulic cylinder 44 providing linear driving force is fixedly mounted. The hydraulic cylinder 44 is existing technology, including HYT-10, DG type, and HSG type, etc. Different models of hydraulic cylinder 44 are used for processing workpieces of different materials; specific models will not be detailed here. The appropriate model of hydraulic cylinder 44 needs to be selected according to the material of the stamping workpiece. The output shaft of the hydraulic cylinder 44 extends downward, passes through the top plate 43, and is connected to a drive plate 45. When the hydraulic cylinder 44 is working, its output shaft will extend or shorten, so the drive plate 45 will rise or fall accordingly. In order to make the operation of the hydraulic cylinder 44 more precise and automated, a controller 46 is also installed on the top of the top plate 43 to control the operation of the hydraulic cylinder 44. The specific model of the controller 46 is Boreno Y32-100T, which is a programmable controller. Four vertically extending stabilizing telescopic rods 47 are also fixedly connected to the bottom of the top plate 43. The stabilizing telescopic rods 47 can extend or shorten.

[0024] The above is the content disclosed in this technical solution regarding conventional hydraulic frames.

[0025] Please refer to 1-13. A stamping die spring material device includes a lower die 1. A mounting block is fixedly connected to the side of the lower die 1. The mounting block is bolted to the top of a base plate 41. A lifting plate 8 is also provided above the lower die 1. Two threaded posts 40 are fixedly connected to the top of the lifting plate 8. The threaded posts 40 pass through a drive plate 45. Nuts are threaded onto the surface of the threaded posts 40. Thus, the lifting plate 8 and the drive plate 45 are fixedly installed using the nuts and threaded posts 40. The top of the lifting plate 8 is fixedly connected to the bottom end of a stabilizing telescopic rod 47. The movement trajectory of the lifting plate 8 is limited by the four stabilizing telescopic rods 47, so that the lifting plate 8 can only perform linear lifting and lowering movements. This also addresses the input of the hydraulic cylinder 44. The output shaft is protected to prevent the hydraulic cylinder 44 output shaft from being subjected to forces in directions other than the vertical direction. When the hydraulic cylinder 44 works, it can drive the lifting plate 8 to move up and down. The lifting plate 8 is a horizontally set plate with an upper mold 2 at its bottom that works in conjunction with the lower mold 1. The side of the upper mold 2 is also fixedly connected to a mounting block, which is also installed at the bottom of the lifting plate 8 by bolts. The top of the lower mold 1 has a convex ring, and an inner groove for stamping is machined on the inner side of the convex ring. The bottom of the upper mold 2 has an outer ring and a downward protruding block. When the upper mold 2 stamps downward, it works in conjunction with the lower mold 1 to punch out a workpiece with a concave center.

[0026] During the production process, the lower mold 1 has a circular receiving groove 9 integrally machined at its bottom and a notch 50 integrally machined on its side, which communicates with the receiving groove 9. A spring plate 3 is installed inside the receiving groove 9. Two telescopic rods 10 are fixedly connected to the bottom of the spring plate 3. The telescopic rods 10 can extend or retract, and their bottom ends are fixedly connected to the top of the base plate 41. The arrangement of the two telescopic rods 10 restricts the spring plate 3 to linear lifting and lowering within the receiving groove 9. Each telescopic rod 10 is also fitted with a spring 11. Several cylindrical spring columns 4 are fixedly connected to the top of the spring plate 3. The tops of the spring columns 4 penetrate the lower mold 1 and extend to the top of the lower mold 1. Inside the groove, the spring column 4 and the lower mold 1 are movably connected. The lower mold 1 does not affect the up-and-down movement of the spring column 4. Each spring column 4 has a hemispherical protrusion 38 fixedly glued to its top. As shown in the figure, the uppermost edge of the protrusion 38 is at the same level as the top plane of the top ring of the lower mold 1. The purpose of this setting is to ensure that when the spring column 4 pushes the stamped workpiece upward with the protrusion 38, the entire stamped workpiece will move to the outside of the lower mold 1. In this way, when there is a lateral pushing force laterally, the lower mold 1 will not affect the horizontal movement of the stamped workpiece. The protrusion 38 is made of rubber, so when the spring column 4 pushes the workpiece upward, it can protect the workpiece and avoid hard collisions that could damage the workpiece.

[0027] Two guide frames 12 are fixedly connected to the top of the base plate 41, while a cylindrical support beam 15 is provided on the side of the lower mold 1. Four support columns 42 are provided, with each end of the support beam 15 fixedly connected to two of the four support columns 42. A rope 13 is fixedly connected to the bottom of the spring plate 3. The end of the rope 13 away from the spring plate 3 passes through the two guide frames 12, passes over the top of the support beam 15, and finally connects to a driving plate 14. The guide frame 12 is specifically composed of two plates fixedly connected by a circular pivot. This configuration of the guide frame 12 guides the direction of the rope 13 while reducing friction with the rope 13 due to the circular pivot, facilitating force transmission, significantly reducing rope 13 wear, and extending its service life. When the drive plate 14 moves downward under force, the force is transmitted to the spring plate 3 through the rope 13, causing the spring plate 3 to move downward. The telescopic rod 10 and the spring 11 will then shorten. When the force driving the drive plate 14 downward disappears, the spring 11 will tend to return to its original position and extend. The spring 11 will drive the spring plate 3 upward. The bottom of the drive plate 14 is fixedly connected to three vertically extending downward limiting telescopic rods 49. The limiting telescopic rods 49 can extend or shorten. The bottom ends of the three limiting telescopic rods 49 are fixedly connected to a limiting plate 48, which is fixedly connected to the side of the base plate 41. In this way, the position of the limiting plate 48 is fixed. The setting of the three limiting telescopic rods 49 also limits the movement of the drive plate 14, so that the drive plate 14 can only move in a straight line relative to the limiting plate 48.

[0028] A vertically mounted fixing plate 5 is installed between the two support columns 42 of the mounting beam 15. The front and rear sides of the fixing plate 5 are fixedly connected to the two support columns 42 respectively. Two horizontally extending telescopic rods 16 are fixedly connected to the sides of the fixing plate 5. The telescopic rods 16 can be extended or shortened. The ends of the two telescopic rods 16 away from the fixing plate 5 are fixedly connected to the push plate 7. The sides of the push plate 7 are fixedly glued with soft pads 39, which are made of rubber. The soft pads 39 protect the workpiece when the push plate 7 pushes it, preventing hard impacts that could damage the workpiece. The vertical position of the push plate 7 extends beyond the edge of the lower mold 1, meaning that the push plate 7 is above the lower mold 1. Springs 6 are fitted on the surface of the telescopic rods 16. A cylindrical beam 18 is installed above the fixing plate 5. The two ends of the beam 18 are fixedly connected to the two support columns 42 respectively. (See the attached instruction manual.) Figure 12It is evident that the positions of the fixed plate 5 and the slide 52 are staggered. A moving strip 19 is installed between the fixed plate 5 and the second beam 18. The front and rear sides of the moving strip 19 are slidably connected to the two slides 52 respectively. The vertical cross-section of the moving strip 19 is rectangular, and its front and rear sides are in contact with the inner wall of the slide 52. Furthermore, the top of the moving strip 19 is in contact with the top of the inner wall of the slide 52. This restricts the movement of the moving strip 19, allowing it to only perform linear lifting and lowering movements. A second rope 17 is fixedly connected to the side of the push plate 7. The end of the second rope 17 away from the push plate 7 passes through the top of the second beam 18 and is fixedly connected to the top of the moving strip 19. An elastic plate 20, specifically a stainless steel elastic plate, is fixedly connected to the bottom of the moving strip 19. Figure 5 From a visual perspective, the elastic plate 20 deforms and returns to its original position from side to side. A second driving plate 53 is fixedly welded to its side. When a force is applied to the top of the second driving plate 53, it causes the elastic plate 20 to move downwards. This force is transmitted to the pusher plate 7 via the second rope 17, causing the pusher plate 7 to move closer to the fixed plate 5. Because the moving bar 19 can only move in a straight line, and the force is also vertically downwards, the elastic plate 20 does not deform from side to side. A locking block 21 is fixedly welded to the side of the elastic plate 20. The locking block 21 is a trapezoidal structure with its long vertical surface fixedly connected to the elastic plate 20 and its inclined surface facing downwards. Thus, when the moving bar 19 moves downwards, the fixed plate 5 first presses the locking block 21 through its inclined surface, causing the elastic plate 20 to bend and deform to the right. As the moving bar 19 gradually moves downwards, when the top plane of the locking block 21 exceeds the lower edge of the fixed plate 5, the elastic plate 20's elastic properties are activated. This resets the plate to a vertical position, causing the locking block 21 to engage with the lower edge of the fixed plate 5. After the downward pressure on the second plate 53 disappears, the second spring 6 can no longer drive the pusher plate 7 away from the fixed plate 5, thus locking the pusher plate 7. In this technical solution, ropes 13 and 17 are Kevlar static ropes, not elastic ropes. This design ensures that ropes 13 and 17 can effectively transmit the pulling force. Furthermore, in the state shown in the figure, ropes 13 and 17 are taut, and direct connections between the ropes and plates, blocks, or other structures are unstable. Therefore, in this technical solution, both ends of ropes 13 and 17 are fixedly bolted with connecting rings 51. Using the connecting rings 51 to connect with other structures is more convenient. In the drawing of this technical solution, the connecting rings 51 on the first driving plate 14, the pusher plate 7, and the second driving plate 53 have been omitted, but the instruction manual includes... Figure 6 The specific shape of the connecting ring 51 can be seen. The bottom of the spring plate 3 is fixedly connected to the connecting ring 51. The driving plate 14, the push plate 7 and the driving plate 2 53 are also fixedly connected to their corresponding connecting rings 51.

[0029] The spring plate 3 has no locking structure, while the push plate 7 has a locking structure. Therefore, when the force driving the spring plate 3 to move downward disappears, the spring plate 3 will move upward directly due to the return extension of the spring 11. However, the push plate 7 will not. When the force driving the motion bar 19 to move downward disappears, the push plate 7 will not move horizontally directly because the locking block 21 is locked at the lower edge of the fixed plate 5.

[0030] To enable the downward movement of the first driving plate 14 and the second driving plate 53 using the linear driving force of the hydraulic cylinder 44, a bending frame 22 is fixedly welded to the top of the lifting plate 8. A horizontally positioned moving plate 23 is fixedly welded to the bent extension end of the bending frame 22. During production, the top plate 43 has a slot integrally machined on its side corresponding to the position of the bending frame 22. The upward bending of the bending frame 22 is due to the presence of the second beam 18, which provides sufficient space for the moving plate 23 to move downward. A vertical plate 24 is fixedly connected to the bottom of the moving plate 23. Two telescopic rods 25 are fixedly connected to the bottom of the vertical plate 24. The telescopic rods 25 can be extended or shortened. The bottom ends of the two telescopic rods 25 are fixedly connected by a pressure plate 26. A spring 27 is fitted on the surface of the telescopic rods 25. One end of the spring 27 is fixedly connected to the vertical plate 24, and the other end is fixedly connected to the pressure plate 26. With the fixed connection, as the lifting plate 8 moves downward, the pressure plate 26 also moves downward, pressing and driving the plate 14 downward. This utilizes the downward driving force of the hydraulic cylinder 44 to drive the spring plate 3 downward. The bottom of the moving plate 23 is fixedly connected to the vertical plate 28, and the bottom of the vertical plate 28 is fixedly connected to two telescopic rods 29. The telescopic rods 29 can be extended or shortened. The bottom ends of the two telescopic rods 29 are fixedly connected to the pressure plate 20. The surface of the telescopic rods 29 is fitted with springs 31. One end of the springs 31 is fixedly connected to the vertical plate 28, and the other end is fixedly connected to the pressure plate 20. When the moving plate 23 moves downward, the pressure plate 20 drives the elastic plate 20 downward through the driving plate 253. The push plate 7 is pulled towards the fixed plate 5. This lateral movement of the push plate 7 also utilizes the linear driving force of the hydraulic cylinder 44.

[0031] The distance between pressure plate 26 and vertical plate 24 can be varied, as can the distance between pressure plate 30 and vertical plate 28. The reason this technical solution uses this method for pressing is to leave a working gap. This is because driving plate 14 has its limit for downward movement, and driving plate 23 also has its limit for downward movement. If a rigid structure is used to directly push driving plate 14 and driving plate 23 downward, special attention must be paid to the motion accuracy. The downward movement of driving plate 14 and driving plate 23 must be very precise to ensure that the lower mold 1 and upper mold 2 can be stamped exactly. The clamping block 21 must also be clamped exactly at the bottom of the fixed plate 5. This is not easy to control. However, by using pressure plate 26 and pressure plate 20 for pressing in this technical solution, there is no need to pay special attention to the motion accuracy.

[0032] Spring 3 (27) has a greater elasticity than spring 1 (11). Therefore, when pressure plate 1 (26) presses down on plate 1 (14), spring 1 (11) will shorten first, followed by spring 3 (27). Spring 4 (31) has a greater elasticity than spring 2 (6). Therefore, when pressure plate 2 (30) presses down on plate 2 (53), spring 2 (6) will shorten first, followed by spring 4 (31). This ensures that the aforementioned working gap is utilized. Springs are a well-established existing technology, and the specific application requirements are known. Therefore, the specific values ​​of the spring elasticity coefficients will not be detailed here.

[0033] Before the lower die 1 and the upper die 2 press the workpiece, that is, during the downward movement of the upper die 2, the spring column 4 will enter the receiving groove 9 due to the downward movement of the spring plate 3.

[0034] To ensure that the spring plate 3 reacts first and moves upward after the downward pressure disappears, while the pusher plate 7 reacts later and moves horizontally, a connecting frame 32 is fixedly connected to the side of the spring plate 3. A connecting frame 34 is connected to the connecting frame 32 via a connecting rod 33. The connecting frames 32 and 34 are of the same specifications; they are both a single frame with an internally welded rotating shaft. The connecting rod 33 is rotatably connected to the rotating shaft. A bent, irregularly shaped frame 35 is fixedly connected to the frame of the connecting frame 34. (See the attached instruction manual.) Figure 5As you can see, the rightmost vertical surface of the irregular frame 35 is flush with the rightmost edge of the fixed plate 5. A slider 36 is slidably connected to the surface of the irregular frame 35. A U-shaped support frame 37 is fixedly connected to the bottom of the slider 36. The support frame 37 is fixedly connected to the top of the base plate 41, and the irregular frame 35 is also inside the notch 50. The irregular frame 35 is supported by the support frame 37 and the slider 36, so that the irregular frame 35 can only move in a straight line across the top of the base plate 41. When the spring plate 3 moves downward, the force will be transmitted through the connecting frame 32 and the connecting rod. 33 and connecting frame 2 34 are transferred to the irregular frame 35, and the irregular frame 35 will move in a straight line towards the spring plate 3. During the downward movement of the lifting plate 8, the pressure plate 1 26 and pressure plate 2 30 will drive the driving plate 1 14 and driving plate 2 53 respectively. However, the spring plate 3 will move before the push plate 7. This means that when the locking block 21 is about to be locked on the lower edge of the fixed plate 5, the vertical surface of the irregular frame 35 away from the connecting frame 2 34 has already been offset from the vertical surface of the right side of the fixed plate 5. The irregular frame 35 will not affect the locking block 21 being locked on the fixed plate 5.

[0035] The lateral movement of the pusher plate 7 is achieved by driving the second plate 53 to move downward. When the second pressure plate 30 presses down on the second plate 53 and moves downward, the upper mold 2 will not contact the top of the pusher plate 7. When the second pressure plate 30 continues to move downward, the pusher plate 7 will move towards the fixed plate 5. The upper mold 2 will also continue to move downward. The pusher plate 7 will first detach from directly above the lower mold 1, and then the upper mold 2 will pass the position of the pusher plate 7 as shown in the figure. The upper mold 2 will be offset from the pusher plate 7, and the lifting plate 8 will also be offset from the pusher plate 8, so it will not collide with the upper mold 2.

[0036] Based on the foregoing description, when the locking block 21 is engaged at the lower edge of the fixed plate 5, it locks the pusher plate 7. When the downward pressure disappears, the spring plate 3 will be reset by the spring force of the first spring 11 and move upward. The upward force of the spring plate 3 will be transmitted to the irregular frame 35 through the first connecting frame 32, the connecting rod 33 and the second connecting frame 34. The irregular frame 35 will move in a straight line away from the spring plate 3, and the vertical plane of its bent extension end will push the locking block 21 to move. The locking block 21 will disengage from the lower edge of the fixed plate 5. At this time, the locking of the pusher plate 7 will be released, and the second spring 6 will tend to extend and reset. The second spring 6 will drive the pusher plate 7 to move away from the fixed plate 5. The upward movement of the spring plate 3 will drive the spring column 4 to move upward. The spring column 4, in conjunction with the protrusion 38, will lift the workpiece from the inner groove at the top of the lower mold 1. The pusher plate 7, in conjunction with the soft pad 39, will push away the workpiece located at the top of the lower mold 1 and the protrusion 38.

[0037] Finally, it should be noted that whether the spring plate 3 moves upward instantaneously or slowly does not affect the lifting of the workpiece. To make the spring plate 3 move upward instantaneously, the output shaft of the hydraulic cylinder 44 needs to shorten rapidly after stamping, causing the pressure plate 26 to quickly separate from the driving plate 14. In this way, the spring 11 will drive the spring plate 3 to move upward rapidly, which is an instantaneous movement. When the output shaft of the hydraulic cylinder 44 shortens slowly, the pressure plate 26 will move upward slowly, and the spring 11 will slowly return to its original position and extend, causing the spring plate 3 to move upward slowly. The spring plate 3 can still slowly lift the workpiece using the spring column 4 and the protrusion 38, but the pushing operation of the pusher plate 7 is an instantaneous movement because of the jamming block. The separation of 21 from the fixed plate 5 is instantaneous. Spring 26 will quickly return to its original position and extend, thereby driving the pusher plate 7 to move laterally quickly, which is an instantaneous movement. The rapid extension of spring 26 will provide an inertial force for the workpiece movement, so that the workpiece at the top of the lower mold 1 can be pushed away effectively. However, if the workpiece is pushed slowly, it cannot be pushed a long distance effectively. When pushing the workpiece, a box can be placed in the direction of the workpiece's movement, that is, at the location corresponding to the bottom plate 41, to catch the workpiece. Alternatively, a soft cushioning item such as a towel can be laid down to prevent the workpiece from falling directly and being deformed. This is the conventional understanding of using machinery and protecting workpieces, and this technical solution will not be described in detail.

[0038] In use, the workpiece is placed on top of the lower mold 1. The controller 46 controls the hydraulic cylinder 44 to work, and the output shaft of the hydraulic cylinder 44 extends. The lower mold 1 and the upper mold 2 cooperate to complete the stamping deformation of the workpiece. During the downward movement of the upper mold 2, the pressure plate 26 pushes the drive plate 14 downward, and the drive plate 14 pulls the spring plate 3 downward through the spring 11. The telescopic rod 10 and the spring 11 shorten, and the pressure plate 30 drives the elastic plate 20 downward through the drive plate 2 53. The locking block 21 locks into the lower edge of the fixed plate 5. After stamping is completed, The output shaft of hydraulic cylinder 44 will shorten, at which point the downward pressure force will disappear. Spring 11 will drive the spring plate 3 to move upward. The spring plate 3 will lift the workpiece through the spring column 4 and the protrusion 38. The spring plate 3 will drive the irregular frame 35 to move through the connecting frame 1 32, the connecting rod 33 and the connecting frame 2 34. The bent end of the irregular frame 35 will push against the locking block 21. After the locking block 21 is disengaged from the fixed plate 5, spring 2 6 will quickly extend. Spring 2 6 will drive the push plate 7 and the soft pad 39 to move. The push plate 7 and the soft pad 39 will push the workpiece. The workpiece will move horizontally and disengage from the top of the lower mold 1.
