Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to an automatic discharge mechanism for stamping waste. Background Technology

[0002] In the field of mechanical manufacturing, stamping, as a highly efficient workpiece forming process, is widely used in the mass production of metal sheets, profiles, and other parts. Through the cooperation of the stamping head and the die, it can quickly fulfill the processing requirements of workpieces, such as punching, bending, and forming. However, during the stamping process, a large amount of metal scrap is generated as the workpiece is formed. The timely and effective handling of this scrap directly affects the efficiency, safety, and product quality of stamping, becoming one of the key factors restricting the stable operation of the stamping production line.

[0003] Traditional stamping mechanisms mostly lack dedicated automatic scrap removal devices. Scrap generated during stamping typically accumulates directly around the stamping die, on the worktable, or inside the equipment. Once the scrap reaches a certain amount, the stamping process must be paused, and operators must manually remove the scrap. Manual removal consumes a significant amount of processing time, drastically reducing workpiece processing efficiency per unit time. While some stamping mechanisms do have scrap removal systems, their structures are more complex and require additional drive sources, resulting in higher costs. Again, once the scrap reaches a certain amount, the stamping process must be paused, and operators must manually remove the scrap. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic waste discharge mechanism for stamping. The waste is discharged automatically, and no manual cleaning of waste is required throughout the process, which greatly reduces the manual operation steps.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic discharge mechanism for stamping waste includes a base plate, with multiple support plates fixedly connected to the upper side of the base plate. A first stamping plate is fixedly connected to the top of the support plates. A top plate is disposed above the first stamping plate. Pads are fixedly connected to the upper sides of both the left and right ends of the base plate. A fixing plate is fixedly connected to the upper side of the pads. An opening is provided at the front end of the fixing plate. A rotating shaft is fixedly connected to the middle of the fixing plate. A gear is rotatably connected to the outside of the rotating shaft. A first rack is meshed with the lower left end of the gear. The outer wall of the first rack is slidably connected to the lower end of the fixing plate. A connecting rod is fixedly connected to the front end of the first rack. Multiple hinges are fixedly connected to the outside of the connecting rod. A guide plate is fixedly connected to the rear end of the hinge. The rear end of the guide plate is disposed between the multiple support plates. A second rack is meshed with the front right end of the gear. The upper end of the second rack is connected to the top plate through a connecting assembly.

[0006] Furthermore, the connecting assembly includes a second fixing post fixedly connected to the lower sides of the left and right ends of the top plate, a first fixing post fixedly connected to the lower side of the second fixing post, and a groove formed inside the lower end of the first fixing post.

[0007] Furthermore, the upper end of the second rack is disposed inside the groove, and a bolt is inserted through the upper end of the second rack, the two ends of which are fixedly connected to the inside of the first fixing post.

[0008] Furthermore, a housing is rotatably connected to both the front and rear sides of the lower end of the first fixed column, and a roller is rotatably connected to the inner side of the lower end of the housing.

[0009] Furthermore, a stamping groove is provided on the upper side of the first stamping plate, and a discharge port is provided on the lower side of the first stamping plate.

[0010] Furthermore, a second stamping plate is fixedly connected to the lower side of the top plate, and a stamping head is provided inside the second stamping plate.

[0011] Furthermore, limit rods are fixedly connected to the lower sides of both the front and rear ends of the top plate, and the lower ends of the limit rods are movably connected to the interior of both the front and rear ends of the first stamping plate.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the up-and-down movement of the top plate serves as the core power source, synchronously driving the stamping operation and the waste discharge process. The debris generated by stamping automatically falls to the guide plate through the discharge port, and then the guide plate is driven to reciprocate through the linkage of rack and pinion and gear. Combined with the inertia of the waste, it is automatically discharged. There is no need for manual cleaning of waste throughout the process, which greatly reduces the manual operation links.

[0013] 2. In this utility model, the first fixed column and the second fixed column drive the second rack, thereby triggering the linkage between the gear, the first rack and the guide plate. There is no need to configure an additional driving device such as a motor and cylinder for waste discharge, which significantly simplifies the overall structure of the mechanism and reduces the manufacturing cost and assembly complexity of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-6This utility model provides an embodiment of an automatic discharge mechanism for stamping waste, comprising a base plate 1, multiple support plates 2 fixedly connected to the upper side of the base plate 1, a first stamping plate 3 fixedly connected to the top of the support plates 2, a top plate 18 above the first stamping plate 3, pads 5 fixedly connected to the upper sides of both the left and right ends of the base plate 1, a fixing plate 6 fixedly connected to the upper side of the pads 5, an opening 7 at the front end of the fixing plate 6, a rotating shaft 8 fixedly connected to the middle of the fixing plate 6, a gear 9 rotatably connected to the outside of the rotating shaft 8, a first rack 10 meshing with the lower left end of the gear 9, the outer wall of the first rack 10 slidingly connected to the lower end of the fixing plate 6, a connecting rod 11 fixedly connected to the front end of the first rack 10, and multiple hinges 12 fixedly connected to the outside of the connecting rod 11. The rear end of the hinge 12 is fixedly connected to a guide plate 4. The rear end of the guide plate 4 is located between multiple support plates 2. The front right side of the gear 9 is meshed with a second rack 13. The upper end of the second rack 13 is connected to the top plate 18 through a connecting assembly. The connecting assembly includes a second fixing post 17 fixedly connected to the lower sides of the left and right ends of the top plate 18. A first fixing post 14 is fixedly connected to the lower side of the second fixing post 17. A groove 15 is provided inside the lower end of the first fixing post 14. The upper end of the second rack 13 is located inside the groove 15. A bolt 16 passes through the upper end of the second rack 13. The two ends of the bolt 16 are fixedly connected to the inside of the first fixing post 14. A housing 22 is rotatably connected to the front and rear sides of the lower end of the first fixing post 14. A roller 23 is rotatably connected to the inner side of the lower end of the housing 22.

[0018] As the top plate 18 moves up and down, the second fixed posts 17, which are fixedly connected to the lower sides of its left and right ends, move synchronously, thereby driving the first fixed post 14, which is connected to the lower side of the second fixed post 17, to move vertically together. Since the upper end of the second rack 13 is movably connected to the groove 15 at the lower end of the first fixed post 14 through the bolt 16, the up and down movement of the first fixed post 14 directly drives the second rack 13 to move vertically. When the second rack 13 moves vertically, it meshes with the front right end of the gear 9, which is rotatably connected to the outer side of the rotating shaft 8 in the middle of the fixed plate 6, causing the gear 9 to rotate clockwise or counterclockwise around the rotating shaft 8. Since the lower left end of the gear 9 is connected to the first rack The gears 10 mesh, and the rotation of the gear 9 is further converted into the horizontal movement of the first rack 10, causing the first rack 10 to move back and forth along the sliding track inside the lower end of the fixed plate 6. When the first rack 10 moves back and forth, the connecting rod 11 connected to its front end moves synchronously. Through the multiple hinges 12 fixed on the outside of the connecting rod 11, the guide plate 4 connected to the rear end of the hinge 12 is driven to move back and forth between the support plates 2. The waste falling on the guide plate 4 will gain a forward or backward movement tendency under the drive of the guide plate 4. Combined with the inertia of the waste itself, it will gradually move to the rear end of the guide plate 4 and finally detach from the guide plate 4, completing the automatic discharge of the waste.

[0019] Reference Figures 1-6 The upper side of the first stamping plate 3 is provided with a stamping groove 19, the lower side of the first stamping plate 3 is provided with a discharge port 20, the lower side of the top plate 18 is fixedly connected with a second stamping plate 21, the interior of the second stamping plate 21 is provided with a stamping head, and the lower sides of the front and rear ends of the top plate 18 are fixedly connected with limit rods 24, the lower ends of the limit rods 24 are movably connected to the interior of the front and rear ends of the first stamping plate 3.

[0020] Powered by an externally configured drive source, the top plate 18 at the top of the drive mechanism reciprocates vertically. During its vertical movement, the top plate 18 simultaneously drives the second stamping plate 21 fixedly connected to its lower side and the stamping head installed inside the plate. At the same time, the limiting rods 24 on the lower sides of the front and rear ends of the top plate 18 slide up and down synchronously along the internal movable holes at the front and rear ends of the first stamping plate 3, ensuring the stability of the top plate 18 and the second stamping plate 21 during movement and preventing deviation. When the top plate 18 drives the stamping head to move downward, the stamping head precisely engages with the stamping groove 19 opened on the upper side of the first stamping plate 3 to perform stamping processing on the workpiece. The debris generated during the stamping process falls naturally into the guide plate 4 between the multiple support plates 2 below the first stamping plate 3 through the discharge port 20 connected to the stamping groove 19 on the lower side of the first stamping plate 3, completing the stamping operation and the initial collection of waste.

[0021] Working principle: An externally installed drive source drives the top plate 18 to move up and down, which in turn drives the second stamping plate 21 and the stamping head to move up and down. The stamping head cooperates with the stamping groove 19 and the discharge port 20 to perform stamping. The debris generated by stamping is discharged from the lower side of the first stamping plate 3 through the discharge port 20 and falls onto the guide plate 4. The up and down movement of the top plate 18 drives the second fixed column 17 and the first fixed column 14 to move up and down, which in turn drives the second rack 13 to move up and down. The moving second rack 13 drives the gear 9 to rotate, and the rotating gear 9 drives the lower first rack 10 to move back and forth, which in turn drives the guide plate 4 to move back and forth through the connecting rod 11 and the hinge 12. The back and forth movement of the guide plate 4 drives the debris to move. Due to inertia, the waste gradually moves backward and is discharged from the guide plate 4.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
