[0002] Stamping is an important metal processing method in hardware manufacturing. Stamping is a processing method that uses a punch press and a die to apply pressure to materials such as sheet metal, strip, tube and profile, causing them to separate or plastically deform, thereby obtaining the required shape and size. Existing stamping equipment partially uses manual loading and unloading, and there is no corresponding positioning operation. Every time the material is loaded or unloaded, the worker needs to manually adjust the position of the material, which is not only time-consuming, but also prone to inaccurate positioning, resulting in unstable quality of stamped parts. Utility Model Content

[0021] 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.

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a stamping device for processing hardware parts, comprising: a punch press 1, which is a mechanical punch press, and includes a power drive and a transmission system; the power drive is a motor that drives a flywheel to rotate. In the transmission system, the flywheel drives a large gear through a shaft and a small gear, and the large gear then drives the crankshaft to rotate through a clutch. The crankshaft drives the connecting rod to move the slider up and down, completing the stamping action. A stamping head 2 is installed at the bottom of the slider of the punch press 1. A stamping groove 17 is provided below the stamping head 2. The stamping groove 17 is a circular groove structure and has a hole inside that mates with the stamping head 2. The feeding assembly is located on one side of the punch press 1. The feeding assembly includes a storage rack 4 for storing materials and a linear module 5 for driving the materials to rise. The loading assembly is located in the middle of the punch press 1. The loading assembly includes three sets of vacuum suction cups 11 arranged at equal intervals and a drive unit for driving the vacuum suction cups 11 to rise, fall and slide. The positioning assembly is located in the middle of the punch press 1. The positioning assembly includes a positioning ring 12 and a positioning block 14 that slides inside the positioning ring 12. The distance between the stamping groove 17 and the positioning ring 12 is the same as the distance between two adjacent vacuum suction cups 11. The positions of the three vacuum suction cups 11 correspond one-to-one with the transverse sliding plate 9, the positioning ring 12 and the stamping groove 17.

[0023] It should be noted that this utility model is equipped with a controller and a corresponding operation panel. Circular workpieces are stacked in the storage rack 4. The linear module 5 drives the circular workpieces upwards. The drive unit drives the vacuum suction cup 11 to pick up the material downwards. The three vacuum suction cups 11 then move into the transverse sliding plate 9, the positioning ring 12, and the stamping groove 17 respectively, thereby simultaneously adsorbing and extracting workpieces from the three positions. After being lifted and reset, the workpieces move laterally, taking material from the transverse sliding plate 9 and placing it into the positioning ring 12. The workpieces inside the positioning ring 12 are then placed into the stamping groove 17. The workpieces inside the stamping groove 17 are then removed and placed above the loading device. When the vacuum suction cup 11 and the stamping groove 17 are misaligned, under the action of the limit switch, the punch press 1 drives the stamping head 2 to perform a stamping operation on the workpiece inside the stamping groove 17. This cycle is repeated to achieve workpiece loading, positioning, and unloading.

[0024] Please see Figure 1 , 5As shown, the feeding assembly also includes a support base 3 fixed to one side of the punch press 1, a storage rack 4 fixed to the top of the support base 3, and a lifting push plate 18 is provided inside the storage rack 4. The lifting push plate 18 is fixed to the moving slide of the linear module 5.

[0025] It should be noted that, under the action of the timer, the linear module 5 drives the lifting push plate 18 to rise intermittently. The height of each rise is the same as the thickness of the workpiece. The workpiece at the top is always in coordination with the vacuum suction cup 11 when picking up the material. After the workpiece at the top is taken away, the linear module 5 lifts and promptly transports the workpiece upward through the lifting push plate 18.

[0026] Please see Figure 1 , 2 As shown, the drive unit includes a lifting bracket 6 fixedly connected to the middle of the punch press 1. A lifting sleeve 7 is slidably connected to the outside of the lifting bracket 6. A cylinder 8 is fixedly connected to the outside of the lifting sleeve 7. The fixed end of the cylinder 8 is fixedly connected to the punch press 1 through the bracket. The telescopic end of the cylinder 8 is fixedly connected to the guide plate 16.

[0027] It should be noted that when the vacuum suction cup 11 is adjusted vertically, the cylinder 8 drives the guide plate 16 to move up and down by extending and retracting. The guide plate 16 drives the lifting sleeve 7 to slide on the outside of the lifting bracket 6, thereby adjusting the height of the vacuum suction cup 11.

[0028] Please see Figure 1 , 2 As shown in Figure 4, a transverse sliding plate 9 is slidably installed on one side of the guide plate 16 along the length direction. Three support plates 10 are fixedly connected at equal intervals on the outer side of the transverse sliding plate 9. The vacuum suction cup 11 is fixedly connected to the corresponding support plate 10. A servo electric cylinder 15 is fixedly connected to the top of the guide plate 16. The output end of the servo electric cylinder 15 is fixedly connected to the transverse sliding plate 9.

[0029] It should be noted that when the vacuum suction cup 11 is adjusted laterally, the second cylinder 15 drives the transverse sliding plate 9 to slide on one side of the guide plate 16. The second cylinder 15 is connected to the transverse sliding plate 9 through a metal plate. A Hall sensor is installed on one side of the transverse sliding plate 9. There are three magnets on the top of the guide plate 16. The three magnets correspond to the three positions where the vacuum suction cup 11 stops. The three positions correspond to the downward material picking position, the transverse material feeding position, and the position where the vacuum suction cup 11 is misaligned with the stamping head 2. During movement, the second cylinder 15 drives the transverse sliding plate 9 to move laterally. The transverse sliding plate 9 drives the vacuum suction cup 11 to move laterally through the support plate 10.

[0030] Please see Figure 3 As shown, three telescopic electromagnets 13 are fixedly connected at equal intervals on the outer side of the positioning ring 12, and the telescopic ends of the telescopic electromagnets 13 are fixedly connected to the positioning block 14.

[0031] It should be noted that when the vacuum suction cup 11 at one end of this utility model carries the workpiece above the positioning ring 12, the vacuum suction cup 11 at the other end places the processed workpiece above the conveying equipment. The cylinder 8 drives the guide plate 16 so that the vacuum suction cup 11 places the workpiece inside the positioning ring 12. The three telescopic electromagnets 13 are energized at the same time, pushing the workpiece downward to the middle from three points on the outside of the workpiece, thereby determining the center of the workpiece. When the vacuum suction cup 11 in the middle drives it and places it inside the stamping groove 17, the size of the inner wall of the stamping groove 17 is adapted to the size of the workpiece. After positioning, it prevents the position from shifting.
