[0070] The lower pressure plate 3012 is used to fix the edge of the guard plate on the support plate 309 to prevent the guard plate from warping during the stamping process, thereby greatly ensuring the quality of the stamping of the guard plate. The second spring 3013 is provided to facilitate the reset of the lower pressure plate 3012.

[0071] As an optimization solution of this embodiment, Figure 7As shown, the ejection mechanism 9 includes a lifting plate 902, a moving block 903, a push-pull rod 901, a blocking plate 906, a third spring 905 and a guide rod 904. The lifting plate 902 is arranged in the middle of the strip hole 202, the moving block 903 is fixedly installed in the middle of the lifting plate 902, the guide rod 904 is symmetrically arranged on both sides of the center line of the strip hole 202, the moving block 903 is slidably installed on the guide rod 904, and the two ends of the blocking plate 906 are respectively connected to the bottom of the guide rod 904 arranged on both sides of the center line of the strip hole 202. The third spring 905 is sleeved on the guide rod 904, and the third spring 905 is located between the blocking plate 906 and the moving block 903. The two ends of the push-pull rod 901 are symmetrically arranged on both sides of the lifting plate 902, and the two ends of the push-pull rod 901 are rotatably connected to the end of the lifting plate 902, the sliding plate 307 on the first positioning frame 301 or the sliding plate 307 on the second positioning frame 303. Limit blocks 907 are also fixedly installed on both sides of the lifting plate 902, and the limit blocks 907 are fixedly installed on the top of the moving block 903.

[0072] The ejection mechanism 9 is used to eject the stamped guard plate from the forming groove 201, which greatly improves the efficiency of taking out the formed guard plate. The setting of the limit block 907 is used to limit the lifting plate 902 to prevent the push-pull rod 901 from moving a large distance so that the lifting plate 902 cannot work normally. The sliding plate 307 on the first positioning frame 301 and the second positioning frame 303 moves while driving one end of the push-pull rod 901 to move. The movement of one end of the push-pull rod 901 will push the moving block 903 to move along the guide rod 904. When the sliding plate 307 on the positioning frame 301 and the second positioning frame 303 simultaneously move to a position away from the center of the workbench 2, the lifting plate 902 will be driven to extend from the strip hole 202 under the action of the push-pull rod 901, and the stamped guard plate will be ejected from the forming groove 201. Conversely, the lifting plate 902 will move along the guide rod 904 toward the bottom of the guide rod 904 under the action of the push-pull rod 901, preventing the lifting plate 902 from interfering with the guard plate when the guard plate is stamped, thereby greatly improving the stamping efficiency and quality of the guard plate.

[0073] As an optimization solution of this embodiment, Fig. 9As shown, a pressing member 7 is also fixedly installed on the stamping plate 504, and the pressing member 7 includes a fixed plate 707, a fixed column 703, a lifting rod 701, a first spring 702, a second sliding rod 705 and a pressing block 706. The fixed plate 707 is fixedly installed on the top of the stamping plate 504, and the fixed columns 703 are symmetrically arranged at both ends of the stamping plate 504, and the fixed columns 703 are slidably arranged on the fixed plate 707. The fixed columns 703 serve the purpose of guidance. A fixed block 704 is fixedly installed on the top of the fixed column 703, and the lifting rod 701 slides Installed on the fixed column 703, the first spring 702 is sleeved on the fixed column 703, and the first spring 702 is located between the fixed block 704 and the lifting rod 701, the first spring 702 plays the purpose of buffering and resetting, ensuring the normal operation of the clamping member 7, the second sliding rod 705 is symmetrically arranged at both ends of the lifting rod 701, the second sliding rod 705 is slidably connected to the fixed plate 707, the clamping block 706 is arranged below the fixed plate 707, and the clamping block 706 is fixedly connected to the second sliding rod 705, and the clamping block 706 cooperates with the lower pressure plate 3012.

[0074] The clamping piece 7 cooperates with the pressing piece to fix the guard plate on the top of the support plate 309 and the workbench 2 to prevent the edge of the guard plate from warping during the stamping process, which affects the stamping quality of the guard plate. The first spring 702 is used to drive the lifting rod 701, the second sliding rod 705 and the clamping block 706 to reset.

[0075] The working process is as follows:

[0076] The guard plates to be stamped are continuously placed on the feeding conveyor belt 1, and the guard plates are driven to move under the action of the feeding conveyor belt 1. When the guard plates move to the feeding piece 8, the clamping cylinder 804 contracts and drives the clamping plate 802 to move along the connecting plate 809 until the baffle plate 808 and the clamping plate 802 clamp the guard plates. After the clamping is completed, the extension cylinder 805 drives the clamped guard plates to move toward the workbench 2 until the push cylinder 805 moves the guard plates to a suitable position.

[0077] The positioning cylinder 3021 is turned on to drive the second positioning frame 303 to move toward the middle of the workbench 2. The second rack 305 on the second positioning frame 303 moves to drive the gear 306 to rotate. The gear 306 rotates to drive the first rack 302 to move. The first rack 302 moves to drive the first positioning frame 301 to move. The first positioning frame 301 and the second positioning frame 303 move inward at the same time until the positioning plate 3018 contacts the side wall of the guard plate, thereby achieving the purpose of fixing the guard plate.

[0078] After the guard plate is fixed, the clamping cylinder 804 is opened first to drive the clamping plate 802 to move in the direction opposite to the center line of the connecting plate 809, the guard plate is loosened, and the clamping of the guard plate is stopped. Then, the lifting cylinder 8011 drives the pushing cylinder 805, the clamping cylinder 804, the moving frame 803 and the clamping plate 802 to move upward, and the pushing cylinder 805 contracts to drive the clamping cylinder 804, the moving frame 803 and the clamping plate 802 to reset. Finally, under the action of the lifting cylinder 8011, the pushing cylinder 805, the clamping cylinder 804, the moving frame 803 and the clamping plate 802 are driven to reset, so as to clamp the guard plate that needs to be stamped again.

[0079] The punching cylinder 503 is turned on to drive the punching plate 504 to move downward. During the downward movement, the pressing block 706 contacts the lower pressing plate 3012. As the punching plate 504 moves downward, the pressing block 706 can press the lower pressing plate 3012 and the side pressing plate 3011 onto the support plate 309, thereby achieving the purpose of pressing the edge of the guard plate to prevent the edge of the guard plate from tilting during the punching process of the guard plate. The punching plate 504 continues to move downward to cooperate with the function of the forming groove 201 to achieve the purpose of punching the guard plate.

[0080] After the stamping is completed, the stamping mechanism 5 is reset, and the positioning cylinder 3021 is extended to drive the second positioning frame 303 to move outward from the center line of the workbench 2. The second positioning frame 303 moves outward because the gear 306, the first rack 302 and the second rack 305 cooperate with each other, driving the first positioning frame 301 to move outward. When the first positioning frame 301 and the second positioning frame 303 move outward from the center line of the workbench 2 at the same time, one end of the push-pull rod 901 will be driven to move outward, and the other end of the push-pull rod 901 will drive the moving block 903 and the lifting plate 902 to move upward along the guide rod 904. The lifting plate 902 penetrates the strip hole 202, and the guard plate formed by stamping is ejected from the forming groove 201, thereby improving the material discharge efficiency of the formed guard plate.

[0081] Finally, the stamped guard plate is conveyed to the unloading conveyor belt 6 through the unloading piece 4, so as to achieve the purpose of unloading the guard plate;

[0082] By repeating the above steps, the guard plate can be stamped and formed continuously.
