Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically relating to a fastener forming device for automotive manufacturing. Background Technology

[0002] Automobile fastener forming equipment refers to a general term for specialized automated equipment used to mass-produce automotive-specific fasteners (such as bolts, nuts, screws, rivets, and special clips) efficiently through plastic deformation processing of metal wire or bar stock. Its core process is typically cold heading, and the core equipment is a multi-station cold heading machine. This equipment integrates a series of stations including wire straightening, feeding, cutting, initial heading, fine heading, and thread rolling (or tapping). Under the high-pressure impact of the mold, the metal material undergoes plastic flow at room temperature, ultimately forming a complex-shaped, high-precision, and high-strength finished fastener in one step. It is a key basic equipment for achieving efficient, high-quality, and low-cost production of fasteners in modern automotive manufacturing.

[0003] In the current screw manufacturing process, the coil is first chemically treated, then straightened and cut to obtain a single blank, which is then placed in a forming device to precisely form the screw head in one go. Finally, the tail is threaded. In the current screw head forming process, multiple stamping dies are usually required to process the screw separately, which causes the material to be transported back and forth during the material transfer process, thus increasing the overall processing steps and greatly reducing the forming efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fastener forming device for automobile manufacturing.

[0005] The technical solution adopted to solve the above technical problems is: a fastener forming device for automobile manufacturing, including a base plate, a feeding mechanism fixedly installed on one side of the top of the base plate, and a material transfer mechanism fixedly connected to the front end of the other side of the top of the base plate. The top of the material transfer mechanism is equipped with multiple clamping mechanisms. A lower mold assembly is fixedly installed at the rear end of the other side of the top of the base plate. An upper mold assembly is installed on the lower mold assembly. A receiving box is provided on the top of the base plate near the lower mold assembly.

[0006] Furthermore, the feeding mechanism includes a feeding frame fixedly connected to one side of the top of the base plate, a conveyor belt assembly mounted on the feeding frame, a first motor fixedly mounted on one side of the rear end of the feeding frame, a baffle fixedly connected to one side of the center of the feeding frame, a first cylinder fixedly mounted on the bottom of the feeding frame near the baffle, a mounting plate fixedly connected to the rear end of the feeding frame near the baffle, a second cylinder fixedly mounted on the rear end of the mounting plate, and a stop block fixedly connected to one end of the piston of the second cylinder.

[0007] With the above technical solution, when handling billets, the operator places the billets sequentially on the conveyor belt assembly, starts the first motor, drives the conveyor belt assembly to run, and thus automatically transports the billets. When the first billet is close to the stop block, the piston of the second cylinder contracts, causing the first billet to be transported towards the baffle. At this time, the piston of the second cylinder extends again, driving the stop block to block the second billet, realizing the transport of billets one by one, which facilitates subsequent transfer. When the first billet is close to the baffle, the piston of the first cylinder pushes, thereby driving the billet to rise to a designated position, which facilitates the transfer mechanism and clamping mechanism to transfer it.

[0008] Furthermore, the material transfer mechanism includes a support frame fixedly connected to the front end of the other side of the top of the base plate. Two first slide bars are fixedly connected to the rear end of the top of the support frame. A movable plate is slidably connected to the two first slide bars. Multiple first slide grooves are opened on the top of the movable plate. A second motor is fixedly installed on the front end of one side of the support frame. A turntable is fixedly connected to the rear end of the output shaft of the second motor. An eccentric shaft is fixedly connected to the turntable. A connecting rod is rotatably connected between the eccentric shaft and the movable plate.

[0009] Through the above technical solution, when the clamping mechanism picks up the blank, the first screw, the second screw, the third screw, the fourth screw, and the fifth screw respectively, the second motor is started. The output shaft rotates, driving the turntable to rotate, which in turn drives the eccentric shaft to rotate, which in turn drives the connecting rod to swing, which in turn drives the moving plate to slide on the two first slide bars, thereby driving the clamping mechanism to move back and forth. This causes the blank, the first screw, the second screw, the third screw, the fourth screw, and the fifth screw to move sequentially to the next workstation. The distance the moving plate moves is the distance between the multiple clamping mechanisms, thus moving the processed blank, the first screw, the second screw, the third screw, the fourth screw, and the fifth screw sequentially to the corresponding next workstation, realizing automated processing and improving processing efficiency.

[0010] Furthermore, the clamping mechanism includes a clamp frame, with two second sliding bars fixedly connected to the bottom of the clamp frame, two second sliding grooves opened inside the clamp frame, two clamping seats slidably connected in the two second sliding grooves, a clamp head fixedly connected to each of the two clamping seats, a third sliding groove opened on the inner end face of each of the two clamping seats, a limit block slidably connected in the two third sliding grooves, a third cylinder fixedly installed in the inner center of the clamp frame, and a fourth cylinder fixedly installed in the top of the moving plate.

[0011] Using the above technical solution, when clamping the blank, the first screw, the second screw, the third screw, the fourth screw, and the fifth screw respectively, the fourth cylinder is first activated, and the piston pushes the clamping frame, causing the clamping frame to slide on the moving plate. When it moves to the designated position, the third cylinder is activated, and the piston contracts, causing the limiting block to contract. Under the limiting action of the two second sliding grooves, the two clamping seats are contracted, thereby causing the chuck to clamp the corresponding workpiece.

[0012] Furthermore, the two second slide bars are slidably connected to the corresponding first slide grooves, one end of the third cylinder piston is fixedly connected to the limiting block, and one end of the fourth cylinder piston is fixedly connected to the clamp.

[0013] Through the above technical solution, before clamping the workpiece, the fourth cylinder pushes the two clamps to extend a certain distance, preventing the two clamps from colliding with the workpiece during the movement of the entire clamping mechanism. This ensures that the various mechanism parts do not interfere with each other, improving the smoothness of operation. At the same time, multiple clamping mechanisms, together with the transfer mechanism, can transfer the corresponding workpiece to the corresponding workstation, realizing one-time stamping of the blank. There is no need to place it on other devices for stamping, reducing the steps of transferring the workpiece and improving the overall stamping efficiency.

[0014] Furthermore, the lower die assembly includes a stamping table fixedly connected to the rear end of the other side of the top of the base plate. A first lower die holder, a second lower die holder, a third lower die holder, a fourth lower die holder, and a fifth lower die holder are fixedly installed inside the stamping table. A spring is fixedly connected to the center of the interior of each of the first lower die holder, the second lower die holder, the third lower die holder, the fourth lower die holder, and the top of each of the springs is fixedly connected to a buffer seat. The first lower die holder, in conjunction with the upper die assembly, can stamp the blank into a first screw.

[0015] Through the above technical solution, the second lower mold base, in conjunction with the upper mold assembly, can stamp the first screw into the second screw; the third lower mold base, in conjunction with the upper mold assembly, can stamp the second screw into the third screw; the fourth lower mold base, in conjunction with the mold assembly, can stamp the third screw into the fourth screw; and the fifth lower mold base, in conjunction with the mold assembly, can stamp the fourth screw into the fifth screw.

[0016] Furthermore, the distances between the first lower mold base, the second lower mold base, the third lower mold base, the fourth lower mold base, and the fifth lower mold base are equal.

[0017] The above technical solution enables the material transfer mechanism and multiple clamping mechanisms to accurately transport the workpiece to the first lower die holder, the second lower die holder, the third lower die holder, the fourth lower die holder, and the fifth lower die holder, thereby achieving one-time stamping of the workpiece.

[0018] Furthermore, the upper mold assembly includes two hydraulic cylinders fixedly installed on the top of the stamping table. The bottom ends of the pistons of the two hydraulic cylinders are fixedly connected to a stamping seat. Limiting rods are fixedly connected to the four corners of the top of the stamping seat. A first upper mold seat, a second upper mold seat, a third upper mold seat, a fourth upper mold seat, and a fifth upper mold seat are fixedly installed in the stamping seat.

[0019] Through the above technical solution, the pressing seat is more stable during the lifting process under the action of multiple limit rods, which greatly improves the stability of the first upper die seat, second upper die seat, third upper die seat, fourth upper die seat and fifth upper die seat during the stamping process.

[0020] Furthermore, all of the aforementioned limiting rods extend through the top of the stamping table, and the distances between the first upper die holder, the second upper die holder, the third upper die holder, the fourth upper die holder, and the fifth upper die holder are equal.

[0021] The above technical solution enables the first upper mold base, second upper mold base, third upper mold base, fourth upper mold base and fifth upper mold base to be precisely stamped with the first lower mold base, second lower mold base, third lower mold base, fourth lower mold base and fifth lower mold base, thereby improving the stamping quality and preventing mis-stamping during the stamping process.

[0022] Furthermore, the first lower die holder and the first upper die holder stamp the blank into a first screw, the second lower die holder and the second upper die holder stamp the first screw into a second screw, the third lower die holder and the third upper die holder stamp the second screw into a third screw, the fourth lower die holder and the fourth upper die holder stamp the third screw into a fourth screw, and the fifth lower die holder and the fifth upper die holder stamp the fourth screw into a fifth screw.

[0023] Through the above technical solution, when processing the blank, it is clamped by a corresponding clamping mechanism and moved to the first lower die seat under the action of the transfer mechanism. Two hydraulic cylinders are activated at the corresponding buffer seat to push the stamping seat, thereby causing the first upper die seat to squeeze the blank, forcing the blank into the first lower die seat. After stamping, a spring returns the blank to its initial position, facilitating the subsequent clamping mechanism to clamp and transfer it to the second lower die seat. Similarly, the second upper die seat presses the first screw into the second lower die seat, stamping the first screw into a second screw, which is then clamped and transferred to the third lower die seat by the corresponding clamping mechanism. The process is repeated... The second screw is pressed into the third lower die holder through the third upper die holder, and the second screw is stamped into the third screw. Then, the corresponding clamping mechanism picks it up and transfers it to the fourth lower die holder. Similarly, the third screw is pressed into the fourth lower die holder through the fourth upper die holder, and the third screw is stamped into the fourth screw. Then, the corresponding clamping mechanism picks it up and transfers it to the fifth lower die holder. Similarly, the fourth screw is pressed into the fifth lower die holder through the fifth upper die holder, and the fourth screw is stamped into the fifth screw. In this way, the blank is stamped into the fifth screw in one go. Then, the fifth screw is transferred to the receiving box through the corresponding clamping mechanism, realizing the whole stamping process and automatic material collection, with high automation efficiency.

[0024] The beneficial effects of the present invention are as follows: (1) By designing a material transfer mechanism and multiple clamping mechanisms, the present invention can automatically transfer the corresponding workpiece to the corresponding workstation, which makes it convenient for the subsequent stamping device to stamp it at one time without having to put it into different stamping dies, thus improving stamping efficiency; (2) By designing a lower die assembly and an upper die assembly, the present invention can stamp the blank into the shape of a fifth screw at one time with multiple lower die seats and corresponding multiple upper die seats, without having to change different stamping dies during this period. The forming device can stamp the whole set, greatly improving stamping efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-4As shown, an automobile manufacturing fastener forming device according to this embodiment includes a base plate 1. A feeding mechanism 2 is fixedly installed on one side of the top of the base plate 1. The feeding mechanism 2 includes a feeding frame 201 fixedly connected to one side of the top of the base plate 1. A conveyor belt assembly 202 is installed on the feeding frame 201. A first motor 203 is fixedly installed on one side of the rear end of the feeding frame 201. A baffle 204 is fixedly connected to one side of the center of the feeding frame 201. A first cylinder 205 is fixedly installed at the bottom of the feeding frame 201 near the baffle 204. A mounting plate 206 is fixedly connected to the rear end of the feeding frame 201 near the baffle 204. A second cylinder 207 is fixedly installed at the rear end of the mounting plate 206. The piston of the second cylinder 207... A stop block 208 is fixedly connected to the end. When handling the billet 8, the operator places the billet 8 on the conveyor belt assembly 202 in sequence, starts the first motor 203, drives the conveyor belt assembly 202 to run, and thus automatically transports the billet 8. When the first billet 8 is close to the stop block 208, the piston of the second cylinder 207 retracts, causing the first billet 8 to be transported towards the baffle 204. At this time, the piston of the second cylinder 207 extends again, driving the stop block 208 to block the second billet 8, realizing the transport of the billet 8 one by one, which is convenient for subsequent transfer. When the first billet 8 is close to the baffle 204, the piston of the first cylinder 205 pushes, thereby driving the billet 8 to rise to the designated position, which is convenient for the transfer mechanism 3 and the clamping mechanism 4 to transfer it.

[0029] like Figures 1-6As shown, a material transfer mechanism 3 is fixedly connected to the front end of the other side of the top of the base plate 1. The material transfer mechanism 3 includes a support frame 301 fixedly connected to the front end of the other side of the top of the base plate 1. Two first slide bars 302 are fixedly connected to the rear end of the top of the support frame 301. A moving plate 303 is slidably connected to the two first slide bars 302. The top of the moving plate 303 is provided with multiple first slide grooves 304. A second motor 305 is fixedly installed on the front end of one side of the support frame 301. A turntable 306 is fixedly connected to the rear end of the output shaft of the second motor 305. An eccentric shaft 307 is fixedly connected to the turntable 306. A connecting rod 308 is rotatably connected between the eccentric shaft 307 and the moving plate 303. When the clamping mechanism 4 clamps the blank 8, the first screw 9, the second screw 10, the third screw 11, and the fourth screw respectively, the material transfer mechanism 3 is activated. When screws 12 and 13 are being processed, the second motor 305 is started, and the output shaft rotates to drive the turntable 306 to rotate, which in turn drives the eccentric shaft 307 to rotate, which in turn drives the connecting rod 308 to swing, which in turn drives the moving plate 303 to slide on the two first slide bars 302, which in turn drives the clamping mechanism 4 to move back and forth, thereby moving the blank 8, the first screw 9, the second screw 10, the third screw 11, the fourth screw 12 and the fifth screw 13 sequentially to the next work station. The distance that the moving plate 303 moves is the distance between the multiple clamping mechanisms 4, thereby moving the processed blank 8, the first screw 9, the second screw 10, the third screw 11, the fourth screw 12 and the fifth screw 13 sequentially to the corresponding next work station, realizing automated processing and improving processing efficiency.

[0030] like Figures 1-7As shown, the top of the material transfer mechanism 3 is equipped with multiple clamping mechanisms 4. Each clamping mechanism 4 includes a clamp 401. Two second sliding bars 402 are fixedly connected to the bottom of the clamp 401. Two second sliding grooves 403 are formed inside the clamp 401. Two clamping seats 404 are slidably connected within the two second sliding grooves 403. A chuck 405 is fixedly connected to each of the two clamping seats 404. A third sliding groove 406 is formed on the inner end face of each of the two clamping seats 404. A limit block 407 is slidably connected within the two third sliding grooves 406. A third cylinder 408 is fixedly installed at the center of the clamp 401. A fourth cylinder 409 is fixedly installed on the top of the moving plate 303. When clamping the blank 8, the first screw 9, the second screw 10, the third screw 11, the fourth screw 12, and the fifth screw 13, the fourth cylinder 409 is activated first. The piston pushes the clamp 401, causing the clamp 401 to slide on the moving plate 303. When it moves to the designated position, the cylinder 409 is activated. The third cylinder 408 is activated, and the piston retracts, causing the limiting block 407 to retract. Under the limiting action of the two second slide grooves 403, the two clamping seats 404 retract, thereby causing the chuck 405 to clamp the corresponding workpiece. The two second slide bars 402 are slidably connected to the corresponding first slide grooves 304. One end of the piston of the third cylinder 408 is fixedly connected to the limiting block 407, and one end of the piston of the fourth cylinder 409 is fixedly connected to the clamping frame 401. Before clamping the workpiece, the fourth cylinder 409 pushes the two chucks 405 to extend a certain distance to prevent the two chucks 405 from hitting the workpiece during the movement of the entire clamping mechanism 4, so that the parts of each mechanism do not interfere with each other, improving the smoothness of operation. At the same time, multiple clamping mechanisms 4, together with the transfer mechanism 3, can transfer the corresponding workpiece to the corresponding station, realizing the one-time stamping of the blank 8 without placing it on other devices for stamping, reducing the steps of transferring the workpiece, and improving the overall stamping efficiency.

[0031] like Figures 1-10As shown, a lower mold assembly 5 is fixedly installed at the rear end of the other side of the top of the base plate 1. The lower mold assembly 5 includes a stamping table 501 fixedly connected to the rear end of the other side of the top of the base plate 1. A first lower mold base 502, a second lower mold base 503, a third lower mold base 504, a fourth lower mold base 505, and a fifth lower mold base 506 are fixedly installed in the stamping table 501. A spring 507 is fixedly connected to the center of the interior of each of the first lower mold base 502, the second lower mold base 503, the third lower mold base 504, the fourth lower mold base 505, and the fifth lower mold base 506. A buffer seat 508 is fixedly connected to the top of each of the springs 507. The first lower mold base 502, in conjunction with the upper mold assembly 6, can stamp the blank 8 into a first screw 9. The second lower mold base 503, in conjunction with the mold assembly 6, can stamp the first screw into a first screw. The wire 9 is stamped into the second screw 10. The third lower die holder 504, in conjunction with the die assembly 6, can stamp the second screw 10 into the third screw 11. The fourth lower die holder 505, in conjunction with the die assembly 6, can stamp the third screw 11 into the fourth screw 12. The fifth lower die holder 506, in conjunction with the die assembly 6, can stamp the fourth screw 12 into the fifth screw 13. The distances between the first lower die holder 502, the second lower die holder 503, the third lower die holder 504, the fourth lower die holder 505, and the fifth lower die holder 506 are equal, so that the transfer mechanism 3 and the multiple clamping mechanisms 4 can accurately transport the workpiece to the first lower die holder 502, the second lower die holder 503, the third lower die holder 504, the fourth lower die holder 505, and the fifth lower die holder 506, realizing one-time stamping of the workpiece.

[0032] like Figures 1-10As shown, an upper mold assembly 6 is installed on the lower mold assembly 5. A receiving box 7 is provided on the top of the base plate 1 near the lower mold assembly 5. The upper mold assembly 6 includes two hydraulic cylinders 601 fixedly installed on the top of the stamping table 501. The bottom ends of the pistons of the two hydraulic cylinders 601 are fixedly connected to a stamping seat 602. Limiting rods 603 are fixedly connected to the four corners of the top of the stamping seat 602. A first upper mold seat 604, a second upper mold seat 605, a third upper mold seat 606, a fourth upper mold seat 607, and a fifth upper mold seat 608 are fixedly installed in the stamping seat 602. Under the action of multiple limiting rods 603, the stamping seat 602 is more stable during the lifting and lowering process, greatly improving the stability of the first upper mold seat 604, the second upper mold seat 605, the third upper mold seat 607, and the fifth upper mold seat 608. The stability of the die holder 606, the fourth upper die holder 607, and the fifth upper die holder 608 during stamping is ensured by multiple limiting rods 603 penetrating the top of the stamping table 501. The distances between the first upper die holder 604, the second upper die holder 605, the third upper die holder 606, the fourth upper die holder 607, and the fifth upper die holder 608 are equal, allowing for precise stamping between them and the first lower die holder 502, the second lower die holder 503, the third lower die holder 504, the fourth lower die holder 505, and the fifth lower die holder 506, improving stamping quality and preventing mis-stamping during the stamping process. The first lower die holder 502 and the first... The upper die holder 604 stamps the blank 8 into the first screw 9. The second lower die holder 503 and the second upper die holder 605 stamp the first screw 9 into the second screw 10. The third lower die holder 504 and the third upper die holder 606 stamp the second screw 10 into the third screw 11. The fourth lower die holder 505 and the fourth upper die holder 607 stamp the third screw 11 into the fourth screw 12. The fifth lower die holder 506 and the fifth upper die holder 608 stamp the fourth screw 12 into the fifth screw 13. For the blank 8, it is clamped by the corresponding clamping mechanism 4 and moved to the first lower die holder 502 under the action of the transfer mechanism 3. At the corresponding buffer seat 508, two hydraulic cylinders 601 are activated to push the stamping seat 602, thereby driving the first upper die holder 602. The die holder 604 presses the blank 8, forcing it into the first lower die holder 502. After stamping, the blank 8 is reset by the spring 507, causing the stamped first screw 9 to rise to its initial position, facilitating the subsequent clamping mechanism 4 to pick it up and transfer it to the second lower die holder 503. Similarly, the second upper die holder 605 presses the first screw 9 into the second lower die holder 503, stamping the first screw 9 into the second screw 10, which is then picked up and transferred to the third lower die holder 504 by the corresponding clamping mechanism 4. Similarly, the third upper die holder 606 presses the second screw 10 into the third lower die holder 504, stamping the second screw 10 into the third screw 11, which is then picked up and transferred to the fourth lower die holder 505 by the corresponding clamping mechanism 4.Similarly, the third screw 11 is pressed into the fourth lower mold base 505 via the fourth upper mold base 607, stamping the third screw 11 into the fourth screw 12. Then, the corresponding clamping mechanism 4 clamps and transfers it to the fifth lower mold base 506. Likewise, the fourth screw 12 is pressed into the fifth lower mold base 506 via the fifth upper mold base 608, stamping the fourth screw 12 into the fifth screw 13. Thus, the blank 8 is stamped into the fifth screw 13 in one operation. The corresponding clamping mechanism 4 then transfers the fifth screw 13 into the receiving box 7, completing the entire stamping process with automatic material collection and high automation efficiency.

[0033] The working principle of this embodiment is as follows: When handling the billet 8, the operator places the billet 8 on the conveyor belt assembly 202 in sequence, starts the first motor 203, drives the conveyor belt assembly 202 to run, thereby automatically conveying the billet 8. When the first billet 8 is close to the stop block 208, the piston of the second cylinder 207 retracts, causing the first billet 8 to be conveyed to the baffle 204. At this time, the piston of the second cylinder 207 extends again, driving the stop block 208 to block the second billet 8. When the first billet 8 is close to the baffle 204, the piston of the first cylinder 205 pushes, thereby driving the billet 8 to rise to the designated position. The fourth cylinder 409 is activated, and the piston pushes the clamp 401, causing the clamp 401 to slide on the moving plate 303. When it moves to the designated position, the third cylinder 408 is activated, and the piston retracts, causing the limiting block 407 to retract. Under the limiting action of the two second sliding grooves 403, the two clamping seats 404 retract, thereby causing the chuck 405 to clamp the blank 8. At the same time, the remaining clamping mechanisms 4 clamp the first screw 9, the second screw 10, the third screw 11, the fourth screw 12, and the fifth screw 13 respectively. The second motor 305 is then started, and the output shaft rotates to drive the turntable 306 to rotate, which in turn drives the eccentric shaft 307 to rotate, which in turn drives the connecting rod 308 to swing, which in turn drives the moving plate 303 to slide on the two first slide bars 302, which in turn drives the clamping mechanism 4 to move, which in turn drives the blank 8, the first screw 9, the second screw 10, the third screw 11, the fourth screw 12 and the fifth screw 13 to move on the first lower mold base 502, the second lower mold base 503, the third lower mold base 504, the fourth lower mold base 505 and the fifth lower mold base 506 respectively; Two hydraulic cylinders 601 are activated, pushing the stamping seat 602, which in turn drives the first upper die seat 604 to extrude the blank 8, forcing the blank 8 into the first lower die seat 502, thus stamping the blank 8 into the first screw 9. The blank 8 is then reset by the spring 507, causing the stamped first screw 9 to rise to its initial position, facilitating the subsequent clamping mechanism 4 to pick it up and transfer it to the second lower die seat 503. Similarly, the second upper die seat 605 presses the first screw 9 into the second lower die seat 503, stamping the first screw 9 into the second screw 10. The corresponding clamping mechanism 4 then picks it up and transfers it to the third lower die seat 504. Similarly, the third upper die seat 606 presses the second screw 10 into the third lower die seat 504. Within 4, the second screw 10 is stamped into the third screw 11, and then the corresponding clamping mechanism 4 clamps and transfers it to the fourth lower mold base 505. Similarly, the third screw 11 is pressed into the fourth lower mold base 505 by the fourth upper mold base 607, and the third screw 11 is stamped into the fourth screw 12. Then, the corresponding clamping mechanism 4 clamps and transfers it to the fifth lower mold base 506. Similarly, the fourth screw 12 is pressed into the fifth lower mold base 506 by the fifth upper mold base 608, and the fourth screw 12 is stamped into the fifth screw 13. Thus, the blank 8 is stamped into the fifth screw 13 in one go. Then, the fifth screw 13 is transferred to the receiving box 7 by the corresponding clamping mechanism 4, realizing the whole stamping process and automatic material collection.
