[0002] During the production and processing of hardware precision parts, stamping is required to cause the required plastic deformation or separation of the stamping parts. Existing hardware precision stamping parts use a retractable stamping head to perform stamping operations on the stamping parts placed on the placement seat. The placement seat has a stamping groove that matches the placement of the stamping parts. After stamping is completed, an automatic discharging device is required to take out the hardware precision stamping machine.

[0003] Currently, when a hardware stamping device is stamping, the stamping die and the stamping hole play a role in stamping and forming the metal plate. The formed hardware parts will be stamped into the stamping hole, and the hardware parts may get stuck in the stamping hole.

Then when the installation plate 2 resets, it will drive the connecting rope 11 to move upward, and the connecting rope 11 will drive the connecting plate 6 and the pressing plate 5 to move upward, so as to reset the hardware parts. As the metal plate moves, the metal plate can drive the hardware parts to move and automatically discharge. When the installation plate 2 moves downward, to prevent the connecting rope 11 from interfering with the stamping work, the torsion spring 8 can be used to drive the reeling wheel 9 to rotate to wind and reset the connecting rope 11. By reciprocating like this, it is further convenient for the automatic discharging of the hardware parts and prevents the situation of injury caused by manual discharging by workers.

[0028] Specifically, referring to Figures 1-3 and Figure 5 , A plurality of groups of limiting and guiding wheels 16 are rotatably installed at the upper end of the workbench 1 on both sides of the stamping hole 4. The vertical cross-section of each limiting and guiding wheel 16 is T-shaped. The workbench 1 can play a role of rotationally supporting the limiting and guiding wheels 16, and the T-shaped limiting and guiding wheels can play a role of limiting and conveying the metal plate. Two gears 17 are rotatably installed at the lower end of the workbench 1. The two gears 17 mesh with each other. The rotating shafts of the two gears 17 are fixedly connected with the rotating shaft of one group of limiting and guiding wheels 16. When the gears 17 rotate, they can drive the limiting and guiding wheels 16 to rotate. An L-shaped plate 18 is fixedly installed at the lower end of the workbench 1. A stepping motor 19 is installed on the inner wall of the L-shaped plate 18. The output shaft of the stepping motor 19 is fixedly connected with the rotating shaft of one of the gears 17. The workbench 1 can play a role of fixing the L-shaped plate 18, the L-shaped plate 18 can play a role of fixing the stepping motor 19, and the stepping motor 19 can drive one of the gears 17 to rotate.

[0029] Specifically, referring to Figure 1, on one side of the workbench 1, a guide plate 21 is fixedly connected. The guide plate 21 is inclined. A plurality of sets of feet 20 are fixedly installed at the lower end of the workbench 1. The feet 20 can support the workbench 1, and the workbench 1 can fix the guide plate 21. And the inclined setting of the guide plate 21 facilitates the separate conveyance of the metal plate and the formed object.

[0030] Specifically, refer to Figure 1 , two vertical plates 13 are installed at the upper end of the workbench 1. The upper ends of the two vertical plates 13 are fixedly installed with the same cross plate 14. The workbench 1 can fix the vertical plates 13, and the vertical plates 13 can fix the cross plate 14. A hydraulic rod 15 is installed at the upper end of the cross plate 14. The telescopic end of the hydraulic rod 15 slidably passes through the cross plate 14. The telescopic end of the hydraulic rod 15 is fixedly installed with the mounting plate 2. The cross plate 14 can fix the hydraulic rod 15, and the hydraulic rod 15 can drive the mounting plate 2 to move vertically.

[0031] Specifically, refer to Figure 1 , a controller 22 is fixedly installed on one side of the workbench 1. The controller 22 is electrically connected to the hydraulic rod 15 and the stepping motor 19 respectively. The workbench 1 can fix the controller 22, and the controller 22 can facilitate the operator to operate the stepping motor 19 and the hydraulic rod 15.

[0032] Working principle: When in use, place the metal plate to be stamped between the limit guide wheels 16, ensure that one end of the metal plate is close to the guide plate 21. Start the stepping motor 19 through the controller 22. The output shaft of the stepping motor 19 drives a gear 17 to rotate. Since the two gears 17 are meshed with each other, the two limit guide wheels 16 will rotate in opposite directions. The T-shaped cross-section limit guide wheels 16 roll above and on the side of the metal plate, and guide the metal plate to move forward smoothly through the frictional force until it reaches the stamping hole 4 position; When the metal plate reaches the specified position, the controller 22 controls the hydraulic rod 15 to extend, driving the mounting plate 2 and the upper pressing die 3 to move downward. The upper pressing die 3 cooperates with the stamping hole 4 to stamp the metal plate to form a precision hardware part. At this time, the torsion spring 8 keeps the winding wheel 9 in a winding state to avoid the connecting rope 11 interfering with the stamping process; After stamping, the hydraulic rod 15 contracts, driving the mounting plate 2 and the upper pressing die 3 to rise. At the same time, the connecting rope 11 rises with the mounting plate 2. The connecting rope 11 drives the connecting plate 6 and the pressing plate 5 to move upward, and the pressing plate 5 drives the hardware part to move to the metal plate cutting position. When the metal plate moves, it can drive the hardware part to move out of the material; The metal plate continues to move forward under the guidance of the workbench 1, while the hardware parts drop onto the guide plate 21 due to gravity and slide along the guide plate 21 to the collection area, thereby reducing the need for workers to manually collect materials and reducing the occurrence of workers being injured.
