Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing equipment, and specifically relates to a stamping device for processing automotive stamped parts and its usage method. Background Technique

[0002] Automotive stamped parts are metal stamped parts that make up automotive components. When forming large-area covering parts such as the outer body panel and carriage of a vehicle body, a stamping device is required to perform blanking, bending, stretching, and other forming processes on metal sheets or metal strips. Most of the materials used in stamping are thin metal sheets, and stamping has two states, one is stamping for shaping and the other is stamping for punching holes. Currently, most stamping equipment adopts a design of multi-station synchronous operation.

[0003] Among them, when punching holes, in order to ensure the flatness of the punching edge, the punching components are mostly circular tubular devices. However, in actual use, to ensure uniform pressure on the mold, the bottom of the drilling mold is in a closed state. After the equipment completes punching, the residual debris from stamping will accumulate inside the mold, and the residue of the debris will greatly affect the subsequent stamping accuracy of the equipment. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a stamping device for processing automotive stamped parts, including a base. A support is fixedly connected to the top of the base, and an electric telescopic rod is fixedly connected to the end of the support away from the base. A stamping mechanism, the stamping mechanism includes a sliding plate, a pneumatic box and a fixing ring for installing and fixing the sliding plate, and an extraction component for discharging the waste inside the sliding plate. The end of the electric telescopic rod away from the support is fixedly connected to the top of the pneumatic box. The inner wall of the through hole at the bottom of the pneumatic box is fixedly connected to the outer wall of the fixing ring, and the bottom of the fixing ring is slidably connected to the tops of a plurality of sliding plates.

[0005] Preferably, the extraction component includes a mounting frame connected through the top of the pneumatic box. A pneumatic cylinder is connected through the top of the mounting frame. A piston plate is slidably connected to the inner wall of the pneumatic cylinder. A fixing column is fixedly connected to the top of the piston plate. Before use, install the base at the required position, then place the stamped metal sheet on the top of the base, and then turn on the power of the electric telescopic rod. The extended electric telescopic rod drives the pneumatic box to slide downward synchronously. The pneumatic box drives the sliding plates to slide downward synchronously through the fixing ring. The eight sliding plates will combine to form a complete circular tube. Under the push of the electric telescopic rod, this circular tube stamps the outer wall of the metal sheet to complete the basic stamping process of the equipment, and the waste accumulates inside the circular tube formed by the sliding plates.

[0006] Preferably, the extraction component further includes a rotating blocking plate rotatably connected to the inner wall of the mounting frame. A pulling wire is fixedly connected to the top of the rotating blocking plate. The end of the pulling wire away from the rotating blocking plate is fixedly connected to the bottom of the piston plate. The end of the fixed column away from the piston plate is fixedly connected to the outer wall of the support. A control component is fixedly connected to the outer wall of the air pressure box. When the air pressure box moves downward, since the rotating blocking plate blocks the mounting frame, a closed space is formed by the inner wall of the air pressure cylinder, the top of the mounting frame, and the bottom of the piston plate. As the air pressure cylinder slides downward, the fixed column and the piston plate remain stationary. As the distance between the piston plate and the mounting frame increases, the pressure inside the air pressure cylinder will change from normal pressure to negative pressure. When the equipment completes stamping, at this time, the piston plate will drive the rotating blocking plate to rotate upward around the connection point through the pulling wire, so that the negative pressure inside the air pressure cylinder acts on the inner wall of the sliding plate through the air pressure box, forcing the waste material inside the sliding plate to be extracted by the negative pressure and slide upward along the inner wall of the sliding plate, and finally enter the air pressure box. Through the application of the above components, the waste material generated after stamping is prevented from falling downward into the base, affecting the stamping accuracy of the subsequent mold.

[0007] Preferably, the control component includes a first hydraulic telescopic rod fixedly connected to the support near the electric telescopic rod. A piston block is slidably connected to the inner wall of the first hydraulic telescopic rod. A support rod is fixedly connected to the bottom of the piston block. A first fixing plate is fixedly connected to the side wall of the air pressure box. The end of the support rod away from the piston block is fixedly connected to the outer wall of the first fixing plate. A speed reduction component is fixedly connected to the inner wall of the air pressure cylinder. Before the equipment is used, it is ensured that the first hydraulic telescopic rod is filled with solution.

[0008] Preferably, the control component further includes a second hydraulic telescopic rod fixedly connected to the bottom of the first fixing plate. A transmission hose is connected through the bottom outer wall of the first hydraulic telescopic rod. The end of the transmission hose away from the first hydraulic telescopic rod is connected through the outer wall of the second hydraulic telescopic rod. The end of the second hydraulic telescopic rod away from the first fixing plate is fixedly connected to a second fixing plate. A limiting ring is fixedly connected to the outer wall of the second fixing plate. Eight limiting sliding frames are fixedly connected to the top of the outer wall of the limiting ring. After stamping is completed, the electric telescopic rod contracts, forcing the second hydraulic telescopic rod to contract synchronously. At this time, the upward moving limiting ring will drive the sliding plates to move away from each other through the eight limiting sliding frames. Through the application of the above components, when the sliding plates do not move away from each other, the waste material will be completely blocked inside the sliding plates. When the negative pressure acts on the top of the waste material, the sliding plates may not move upward due to excessive friction with the waste material. When the sliding plates move away from each other, since the contact surface between the sliding plates and the waste material decreases, the friction force decreases accordingly. At this time, the force of the negative pressure can directly extract the waste material into the air pressure box, avoiding the influence of excessive waste material friction on the collection of waste material by the equipment.

[0009] Preferably, the control component further includes an inclined panel fixedly connected to the outer walls of the eight sliding plates. A sliding groove is formed in the outer wall of the inclined panel. One end of the limiting sliding frame away from the limiting ring is slidably connected to the inner wall of the sliding groove. An arc-shaped groove is formed in the inner wall of the sliding plate. An arc-shaped plate is fixedly connected to the side of the sliding plate away from the arc-shaped groove. The outer wall of the arc-shaped plate is slidably connected to the inner wall of the adjacent arc-shaped groove. A first spring is fixedly connected to the side wall of the arc-shaped plate. One end of the first spring away from the arc-shaped plate is fixedly connected to the inner wall of the adjacent arc-shaped groove. By utilizing the characteristic that the above-mentioned electric telescopic rod drives the air pressure box to slide up and down, a control component is arranged inside the device. When the electric telescopic rod extends, at this time, the piston block slides down along the inner wall of the first hydraulic telescopic rod, so that the liquid at the bottom of the piston block is transmitted to the inner wall of the second hydraulic telescopic rod through the transmission hose, forcing the second hydraulic telescopic rod to extend. The extended second hydraulic telescopic rod drives the limiting ring to slide down synchronously through the second fixing plate, and the sliding-down limiting ring drives the eight limiting sliding frames to move down synchronously, so that the limiting sliding frames slide down along the inner wall of the sliding groove. During this process, affected by the inclined surface of the outer surface of the inclined panel, the limiting sliding frames push the sliding plates to approach each other along the bottom of the fixed ring through the inclined panel, so that the eight sliding plates are combined into a complete circular tube for stamping.

[0010] Preferably, the deceleration component includes a support frame fixedly connected to the inner wall of the air pressure cylinder. A second spring is fixedly connected to the bottom of the support frame. One end of the second spring away from the support frame is fixedly connected to the top of the rotating plug plate. A hydraulic cylinder is fixedly connected to the bottom of the support frame. A piston disc is slidably connected to the inner wall of the hydraulic cylinder. By utilizing the characteristic that the above-mentioned sliding plates expand outwards, after the eight sliding plates expand outwards, a longitudinal gap will be generated between the arc-shaped plate and the arc-shaped groove. At this time, the negative-pressure gas will extract air from the outside through the above gap from the bottom of the sliding plate, so that the negative-pressure gas inside the sliding plate extracts the outside air into the air pressure box. During this process, an upward air flow will be generated inside the gap, and the force of the upward air flow will act on the bottom of the waste material. Through the application of the above components, the speed of the waste material moving upwards is increased, and the recycling efficiency of the device is improved.

[0011] Preferably, the deceleration component further includes a limiting rod fixedly connected to the bottom of the piston disc. One end of the limiting rod away from the piston disc is rotatably connected to the top of the rotating plug plate. Four through-hole grooves are formed in the top of the piston disc. A right-angle groove is formed in the top of the through-hole groove. A rotating plate is rotatably connected to the inner wall of the right-angle groove. By utilizing the characteristic that the above-mentioned rotating plug plate rotates upwards around the center under the pull of the pulling wire, a deceleration component is arranged inside the device. When the pulling wire pulls the rotating plug plate to rotate upwards around the center, it presents a state as shown in Figure 10 , and at this time, the rotating plug plate drives the piston disc to slide down along the inner wall of the hydraulic cylinder through the limiting rod, so that the liquid inside the hydraulic cylinder flows upwards through the gap between the through-hole groove and the rotating plate.

[0012] Preferably, the slow-down component further includes a through-hole groove two opened at the top of the piston plate. An installation bracket is fixedly connected to the outer wall of the fixed column. A spring telescopic rod is slidably connected to the inner wall of the through-hole of the installation bracket. A blocking ball is fixedly connected to the bottom of the spring telescopic rod. The flow gap between the rotating plate and the through-hole groove one is reduced, and the speed at which the piston disc slides upward along the inner wall of the hydraulic cylinder is slowed down. Through the application of the above components, the speed of the rotating blocking plate resetting is slowed down, and it is avoided that when the electric telescopic rod contracts, the rotating blocking plate immediately closes the through-hole of the mounting bracket, affecting the negative pressure extraction force after the sliding plate expands outward.

[0013] A usage method of a stamping device for processing automotive stampings includes the following steps: S1: Install the equipment: Before use, install the base at the required position, and then place the metal sheet to be stamped on the top of the base; S2: Connect the power supply: Connect the power supply of the electric telescopic rod. The extended electric telescopic rod drives the air pressure box to slide downward synchronously. The air pressure box drives the sliding plate to slide downward synchronously through the fixed ring, and the eight sliding plates will combine into a complete circular tube; S3: Perform stamping: The circular tube is pushed by the electric telescopic rod to stamp the outer wall of the metal sheet, completing the basic stamping process of the equipment, and the waste material accumulates inside the circular tube formed by the sliding plates.

[0014] The present invention has the following beneficial effects: (1) After the stamping is completed by using the equipment, the waste material will be stuck inside the pipeline. There is a stamping mechanism and an extraction component inside the equipment. Before use, the base is installed at the required position, and then the metal sheet to be stamped is placed on the top of the base. Then the power supply of the electric telescopic rod is connected. The extended electric telescopic rod drives the air pressure box to slide downward synchronously. The air pressure box drives the sliding plate to slide downward synchronously through the fixed ring, and the eight sliding plates will combine into a complete circular tube. The circular tube is pushed by the electric telescopic rod to stamp the outer wall of the metal sheet, completing the basic stamping process of the equipment, and the waste material accumulates inside the circular tube formed by the sliding plates; when the air pressure box moves downward, since the rotating blocking plate blocks the mounting bracket, a closed space is formed by the inner wall of the air pressure cylinder, the top of the mounting bracket, and the bottom of the piston plate. As the air pressure cylinder slides downward, while the fixed column and the piston plate remain stationary, as the distance between the piston plate and the mounting bracket increases, the inside of the air pressure cylinder will change from normal pressure to negative pressure. When the equipment completes stamping, at this time, the piston plate will drive the rotating blocking plate to rotate upward around the connection point through the pulling wire, so that the negative pressure inside the air pressure cylinder acts on the inner wall of the sliding plate through the air pressure box, forcing the waste material inside the sliding plate to be extracted by the negative pressure and slide upward along the inner wall of the sliding plate, and finally enter the air pressure box. Through the application of the above components, it is avoided that the waste material generated after stamping falls downward into the base, affecting the stamping accuracy of the subsequent mold.

[0015] (2) By taking advantage of the feature that the above-mentioned electric telescopic rod drives the air pressure box to slide up and down, a control component is arranged inside the device. When the electric telescopic rod extends, at this time, the piston block slides down along the inner wall of the first hydraulic telescopic rod, so that the liquid at the bottom of the piston block is transmitted to the inner wall of the second hydraulic telescopic rod through the transmission hose, forcing the second hydraulic telescopic rod to extend. The extended second hydraulic telescopic rod drives the limit ring to slide down synchronously through the second fixed plate. The sliding limit ring drives the eight limit sliding frames to move down synchronously, so that the limit sliding frames slide down along the inner wall of the sliding groove. During this process, affected by the inclined surface of the inclined panel, the limit sliding frames push the sliding plate along the bottom of the fixed ring to approach each other through the inclined panel, so that the eight sliding plates are combined into a complete circular tube for stamping. After the stamping is completed, the electric telescopic rod contracts, forcing the second hydraulic telescopic rod to contract synchronously. At this time, the upward moving limit ring will drive the sliding plates to move away from each other through the eight limit sliding frames. Through the application of the above components, when the sliding plates do not move away from each other, the waste will be completely blocked inside the sliding plates. When negative pressure acts on the top of the waste, the sliding plates may not move up due to excessive friction with the waste. When the sliding plates move away from each other, since the contact surface between the sliding plates and the waste decreases and the friction force decreases accordingly, the force of the negative pressure at this time can directly extract the waste into the air pressure box, avoiding the influence of excessive waste friction on the waste collection of the device.

[0016] (3) By taking advantage of the feature that the above-mentioned sliding plates expand outwards, after the eight sliding plates expand outwards, a longitudinal gap will be generated between the arc-shaped plate and the arc-shaped groove. At this time, the negative pressure gas will extract air from the bottom of the sliding plates through the above gaps, so that the negative pressure gas inside the sliding plates extracts external air into the air pressure box. During this process, an upward air flow will be generated inside the gap, and the force of the upward flowing air flow will act on the bottom of the waste. Through the application of the above components, the speed of the waste moving up is increased, and the recovery efficiency of the device is improved.

[0017] (4) By taking advantage of the feature that the above-mentioned rotating blocking plate rotates under the pull of the pulling wire, a speed-reducing component is arranged inside the device. When the pulling wire pulls the rotating blocking plate to rotate upwards around the center, presenting a state as shown in Figure 10 At this time, the rotating blocking plate drives the piston disc to slide down along the inner wall of the hydraulic cylinder through the limit rod, so that the liquid on the inner wall of the hydraulic cylinder flows upwards through the gap between the through-hole groove 1 and the rotating plate, presenting a state as shown in Figure 11 When the rotating blocking plate rotates upwards under the tension of the second spring to close the through-hole of the mounting frame, at this time, the rotating plate will rotate downwards, and the flow gap between the rotating plate and the through-hole groove 1 will be reduced, and the speed of the piston disc sliding up along the inner wall of the hydraulic cylinder will slow down. Through the application of the above components, the speed of the rotating blocking plate resetting is slowed down, avoiding that when the electric telescopic rod contracts, the rotating blocking plate immediately closes the through-hole of the mounting frame, affecting the extraction force of the negative pressure after the sliding plates expand outwards.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1, please refer to Figure 1 - Figure 3 , the present invention is a stamping device for processing automotive stampings, including a base 1, a bracket 11 fixedly connected to the top of the base 1, and an electric telescopic rod 12 fixedly connected to one end of the bracket 11 away from the base 1; A stamping mechanism 2, the stamping mechanism 2 includes a sliding plate 23, a pneumatic box 21 and a fixed ring 22 for installing and fixing the sliding plate 23, and an extraction component 3 for discharging the waste inside the sliding plate 23; One end of the electric telescopic rod 12 away from the bracket 11 is fixedly connected to the top of the pneumatic box 21. The inner wall of the through hole at the bottom of the pneumatic box 21 is fixedly connected to the outer wall of the fixed ring 22. The bottom of the fixed ring 22 is slidably connected to the tops of a plurality of sliding plates 23.

[0023] The extraction component 3 includes a mounting frame 31 connected through the top of the pneumatic box 21. The top of the mounting frame 31 is connected through a pneumatic cylinder 32. A piston plate 33 is slidably connected to the inner wall of the pneumatic cylinder 32. A fixed column 34 is fixedly connected to the top of the piston plate 33. Before use, the base 1 is installed at the required position, and then the stamping metal sheet is placed on the top of the base 1, showing as Figure 3The state of G in the middle, then the power supply of the electric telescopic rod 12 is turned on. The extended electric telescopic rod 12 drives the air pressure box 21 to slide downward synchronously. The air pressure box 21 drives the sliding plate 23 to slide downward synchronously through the fixed ring 22. And the eight sliding plates 23 will combine into a complete circular tube. Driven by the electric telescopic rod 12, this circular tube punches the outer wall of the metal sheet, completing the punching process of the equipment foundation, and the waste materials are accumulated inside the circular tube formed by the sliding plates 23.

[0024] The extraction component 3 further includes a rotating blocking plate 35 rotatably connected to the inner wall of the mounting frame 31. A pulling line 36 is fixedly connected to the top of the rotating blocking plate 35. One end of the pulling line 36 away from the rotating blocking plate 35 is fixedly connected to the bottom of the piston plate 33. One end of the fixed column 34 away from the piston plate 33 is fixedly connected to the outer wall of the support frame 11. A control component 4 is fixedly connected to the outer wall of the air pressure box 21. When the air pressure box 21 moves downward, since the rotating blocking plate 35 blocks the mounting frame 31, a closed space is formed by the inner wall of the air pressure cylinder 32, the top of the mounting frame 31 and the bottom of the piston plate 33. As the air pressure cylinder 32 slides downward, while the fixed column 34 and the piston plate 33 remain stationary. As the distance between the piston plate 33 and the mounting frame 31 increases, the inside of the air pressure cylinder 32 will change from normal air pressure to negative pressure. When the equipment finishes punching, at this time, the piston plate 33 will drive the rotating blocking plate 35 to rotate upward around the connection point through the pulling line 36, so that the negative pressure inside the air pressure cylinder 32 acts on the inner wall of the sliding plate 23 through the air pressure box 21, forcing the waste materials inside the sliding plate 23 to be extracted by the negative pressure, slide upward along the inner wall of the sliding plate 23, and finally enter the inside of the air pressure box 21. Through the application of the above components, it is avoided that the waste materials generated after punching fall downward into the base 1, affecting the punching accuracy of the subsequent mold.

[0025] Embodiment 2, please refer to Figure 4 - Figure 12 , the present invention is a stamping device for processing automotive stamped parts. On the basis of Embodiment 1, the control component 4 includes a first hydraulic telescopic rod 41 fixedly connected to one end of the support frame 11 close to the electric telescopic rod 12. A piston block 42 is slidably connected to the inner wall of the first hydraulic telescopic rod 41. A support rod 43 is fixedly connected to the bottom of the piston block 42. A first fixing plate 44 is fixedly connected to the side wall of the air pressure box 21. One end of the support rod 43 away from the piston block 42 is fixedly connected to the outer wall of the first fixing plate 44. A speed reduction component 5 is fixedly connected to the inner wall of the air pressure cylinder 32. Among them, before the equipment is used, it is ensured that the inside of the first hydraulic telescopic rod 41 is filled with solution.

[0026] The control component 4 further includes a second hydraulic telescopic rod 45 fixedly connected to the bottom of the first fixing plate 44. A transmission hose 46 is connected through the outer wall at the bottom of the first hydraulic telescopic rod 41. One end of the transmission hose 46 away from the first hydraulic telescopic rod 41 is connected through the outer wall of the second hydraulic telescopic rod 45. One end of the second hydraulic telescopic rod 45 away from the first fixing plate 44 is fixedly connected to a second fixing plate 47. A limiting ring 48 is fixedly connected to the outer wall of the second fixing plate 47. Eight limiting sliding frames 49 are fixedly connected to the top of the outer wall of the limiting ring 48. After the stamping is completed, the electric telescopic rod 12 contracts, forcing the second hydraulic telescopic rod 45 to contract synchronously. At this time, the upward moving limiting ring 48 will drive the sliding plates 23 to move away from each other through the eight limiting sliding frames 49, presenting a state as shown in Figure 5 . Through the application of the above components, when the sliding plates 23 do not move away from each other, the waste will be completely blocked inside the sliding plates 23. When negative pressure acts on the top of the waste, the sliding plates 23 may not move upward due to excessive friction with the waste. When the sliding plates 23 move away from each other, since the contact surface between the sliding plates 23 and the waste decreases and the friction force decreases accordingly, the force of the negative pressure can directly extract the waste into the air pressure box 21, avoiding the influence of excessive waste friction on the collection of waste by the equipment.

[0027] The control component 4 further includes inclined panels 410 fixedly connected to the outer walls of the eight sliding plates 23. Sliding grooves 411 are provided on the outer walls of the inclined panels 410. One end of the limiting sliding frame 49 away from the limiting ring 48 is slidably connected to the inner wall of the sliding groove 411. Arc-shaped grooves 412 are provided on the inner walls of the sliding plates 23. One side of the sliding plate 23 away from the arc-shaped groove 412 is fixedly connected to an arc-shaped plate 413. The outer wall of the arc-shaped plate 413 is slidably connected to the inner wall of the adjacent arc-shaped groove 412. A first spring 414 is fixedly connected to the side wall of the arc-shaped plate 413. One end of the first spring 414 away from the arc-shaped plate 413 is fixedly connected to the inner wall of the adjacent arc-shaped groove 412. Utilizing the characteristic that the electric telescopic rod 12 drives the air pressure box 21 to slide up and down, a control component 4 is provided inside the equipment. While the electric telescopic rod 12 extends, at this time, the piston block 42 slides downward along the inner wall of the first hydraulic telescopic rod 41, so that the liquid at the bottom of the piston block 42 is transmitted through the transmission hose 46 to the inner wall of the second hydraulic telescopic rod 45, forcing the second hydraulic telescopic rod 45 to extend. The extended second hydraulic telescopic rod 45 drives the limiting ring 48 to slide downward synchronously through the second fixing plate 47, and the downward moving limiting ring 48 drives the eight limiting sliding frames 49 to move downward synchronously, so that the limiting sliding frames 49 slide downward along the inner wall of the sliding groove 411. During this process, affected by the outer inclined surface of the inclined panel 410, the limiting sliding frames 49 push the sliding plates 23 to approach each other along the bottom of the fixed ring 22 through the inclined panels 410, so that the eight sliding plates 23 are combined into a complete circular tube for stamping.

[0028] The speed reduction component 5 includes a support frame 51 fixedly connected to the inner wall of the pneumatic cylinder 32. A second spring 52 is fixedly connected to the bottom of the support frame 51. One end of the second spring 52 away from the support frame 51 is fixedly connected to the top of the rotating plug plate 35. A hydraulic cylinder 53 is fixedly connected to the bottom of the support frame 51. A piston disc 54 is slidably connected to the inner wall of the hydraulic cylinder 53. Utilizing the characteristic that the sliding plate 23 expands outwards, after the eight sliding plates 23 expand outwards, a longitudinal gap will be generated between the arc plate 413 and the arc groove 412, presenting a state as shown in Figure 8 in F. At this time, the negative pressure gas will extract air from the bottom of the sliding plate 23 through the above gap, enabling the negative pressure gas inside the sliding plate 23 to extract external air into the pneumatic box 21. During this process, an upward air flow will be generated inside the gap, and the upward flowing force of this air flow will act on the bottom of the waste material. Through the application of the above components, the upward movement speed of the waste material is accelerated, and the recycling efficiency of the equipment is improved.

[0029] The speed reduction component 5 further includes a limiting rod 55 fixedly connected to the bottom of the piston disc 54. One end of the limiting rod 55 away from the piston disc 54 is rotatably connected to the top of the rotating plug plate 35. Four through-hole slots 56 are opened at the top of the piston disc 54. A right-angle groove 57 is opened at the top of the through-hole slot 56. A rotating plate 58 is rotatably connected to the inner wall of the right-angle groove 57. Utilizing the characteristic that the rotating plug plate 35 rotates under the pulling of the pulling wire 36, a speed reduction component 5 is provided inside the equipment. When the pulling wire 36 pulls the rotating plug plate 35 to rotate upwards around the center, presenting a state as shown in Figure 10 . At this time, the rotating plug plate 35 drives the piston disc 54 to slide downwards along the inner wall of the hydraulic cylinder 53 through the limiting rod 55, enabling the liquid on the inner wall of the hydraulic cylinder 53 to flow upwards through the gap between the through-hole slot 56 and the rotating plate 58, as shown in Figure 11 . When the rotating plug plate 35 rotates upwards under the pulling force of the second spring 52 to close the through-hole of the mounting frame 31, at this time, the rotating plate 58 will rotate downwards, presenting a state as shown in Figure 11 in G.

[0030] The speed reduction component 5 further includes a through-hole slot 59 opened at the top of the piston plate 33. An installation bracket 512 is fixedly connected to the outer wall of the fixed column 34. A spring telescopic rod 511 is slidably connected to the inner wall of the through-hole of the installation bracket 512. A plug ball 510 is fixedly connected to the bottom of the spring telescopic rod 511. The flow gap between the rotating plate 58 and the through-hole slot 56 is reduced, and the sliding speed of the piston disc 54 upwards along the inner wall of the hydraulic cylinder 53 is slowed down. Through the application of the above components, the reset speed of the rotating plug plate 35 is slowed down, preventing the rotating plug plate 35 from immediately closing the through-hole of the mounting frame 31 when the electric telescopic rod 12 contracts, which affects the negative pressure extraction force after the sliding plate 23 expands outwards.

[0031] The usage method of the stamping device for automobile stamping parts includes the following steps: S1: Install the equipment: Before use, install the base 1 at the required position, and then place the metal sheet to be stamped on the top of the base 1; S2: Connect the power supply: Connect the power supply of the electric telescopic rod 12. The extended electric telescopic rod 12 drives the air pressure box 21 to slide downward synchronously. The air pressure box 21 drives the sliding plate 23 to slide downward synchronously through the fixed ring 22, and the eight sliding plates 23 will combine into a complete circular tube; S3: Perform stamping: The circular tube is pushed by the electric telescopic rod 12 to stamp the outer wall of the metal sheet, completing the stamping process of the equipment foundation, and the waste materials accumulate inside the circular tube formed by the sliding plates 23.

[0032] A specific application of this embodiment is: Before use, install the base 1 at the required position, and then place the metal sheet to be stamped on the top of the base 1, presenting the state as shown in Figure 3 G. Then connect the power supply of the electric telescopic rod 12. The extended electric telescopic rod 12 drives the air pressure box 21 to slide downward synchronously. The air pressure box 21 drives the sliding plate 23 to slide downward synchronously through the fixed ring 22, and the eight sliding plates 23 will combine into a complete circular tube. The circular tube is pushed by the electric telescopic rod 12 to stamp the outer wall of the metal sheet, completing the stamping process of the equipment foundation, and the waste materials accumulate inside the circular tube formed by the sliding plates 23; When the air pressure box 21 moves downward, since the rotating blocking plate 35 blocks the mounting frame 31, a closed space is formed by the inner wall of the air pressure cylinder 32, the top of the mounting frame 31, and the bottom of the piston plate 33. As the air pressure cylinder 32 slides downward, the fixed column 34 and the piston plate 33 do not move. As the distance between the piston plate 33 and the mounting frame 31 increases, the pressure inside the air pressure cylinder 32 will change from normal pressure to negative pressure. When the equipment completes stamping, at this time, the piston plate 33 will drive the rotating blocking plate 35 to rotate upward around the connection point through the pulling wire 36, so that the negative pressure inside the air pressure cylinder 32 acts on the inner wall of the sliding plate 23 through the air pressure box 21, forcing the waste materials inside the sliding plate 23 to be extracted by the negative pressure and slide upward along the inner wall of the sliding plate 23, and finally enter the air pressure box 21. Through the application of the above components, it is avoided that the waste materials generated after stamping fall downward into the base 1, affecting the stamping accuracy of the subsequent mold.

[0033] Before the equipment is used, ensure that the inside of the hydraulic telescopic rod 41 is filled with solution. Utilizing the characteristic that the electric telescopic rod 12 drives the air pressure box 21 to slide up and down, a control component 4 is arranged inside the equipment. When the electric telescopic rod 12 extends, at this time, the piston block 42 slides down along the inner wall of the hydraulic telescopic rod 41, so that the liquid at the bottom of the piston block 42 is transmitted to the inner wall of the hydraulic telescopic rod 45 through the transmission hose 46, forcing the hydraulic telescopic rod 45 to extend. The extended hydraulic telescopic rod 45 drives the limit ring 48 to slide down synchronously through the fixed plate 47. The sliding limit ring 48 drives the eight limit sliding frames 49 to move down synchronously, so that the limit sliding frames 49 slide down along the inner wall of the sliding groove 411. During this process, affected by the outer slope of the inclined panel 410, the limit sliding frame 49 pushes the sliding plate 23 to approach each other along the bottom of the fixed ring 22 through the inclined panel 410, so that the eight sliding plates 23 are combined into a complete circular tube for stamping. After stamping is completed, the electric telescopic rod 12 contracts, forcing the hydraulic telescopic rod 45 to contract synchronously. At this time, the upward moving limit ring 48 will drive the sliding plates 23 to move away from each other through the eight limit sliding frames 49, presenting a state as Figure 5 When the above components are applied, before the sliding plates 23 move away from each other, the waste will be completely blocked inside the sliding plates 23. When negative pressure acts on the top of the waste, the sliding plates 23 may not move up due to excessive friction with the waste. When the sliding plates 23 move away from each other, since the contact surface between the sliding plates 23 and the waste decreases and the friction force decreases accordingly, at this time, the force of the negative pressure can directly extract the waste into the air pressure box 21, avoiding the influence of excessive waste friction on the collection of waste by the equipment.

[0034] Utilizing the characteristic that the above sliding plates 23 expand outwards, after the eight sliding plates 23 expand outwards, a longitudinal gap will be generated between the arc-shaped plate 413 and the arc-shaped groove 412, presenting a state as Figure 8 in F in. At this time, the negative pressure gas will extract air from the bottom of the sliding plates 23 through the above gaps, so that the negative pressure gas inside the sliding plates 23 extracts external air into the air pressure box 21. During this process, an upward air flow will be generated inside the gap, and the force of the upward flowing air flow will act on the bottom of the waste. By applying the above components, the upward movement speed of the waste is accelerated, and the recycling efficiency of the equipment is improved.

[0035] Before use, ensure that the inside of the hydraulic cylinder 53 is filled with liquid. Utilizing the characteristic that the above rotating blocking plate 35 rotates under the pull of the pulling wire 36, a speed reducing component 5 is arranged inside the equipment. When the pulling wire 36 pulls the rotating blocking plate 35 to rotate upwards around the center, presenting a state as Figure 10the state, and at this time, rotating the blocking plate 35 drives the piston disc 54 to slide downward along the inner wall of the hydraulic cylinder 53 through the limiting rod 55, so that the liquid on the inner wall of the hydraulic cylinder 53 flows upward through the gap between the through-hole groove 56 and the rotating plate 58, as Figure 11 the state, and when the rotating blocking plate 35 rotates upward under the tension of the second spring 52 to close the through-hole of the mounting frame 31, at this time, the rotating plate 58 will rotate downward, presenting as Figure 11 the state of G in. At this time, the flow gap between the rotating plate 58 and the through-hole groove 56 is reduced, and the speed of the piston disc 54 sliding upward along the inner wall of the hydraulic cylinder 53 slows down. Through the application of the above components, the speed of the rotating blocking plate 35 resetting is slowed down, and it is avoided that when the electric telescopic rod 12 contracts, the rotating blocking plate 35 immediately closes the through-hole of the mounting frame 31, affecting the suction force of the negative pressure after the sliding plate 23 expands outward.
