[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a feeding device for a punch press, comprising: a punch press body 1, a feeding assembly on one side of the punch press body 1, which feeds materials to avoid the drawbacks of manual feeding; the feeding assembly includes a support platform 2, a geared disc 3 rotatably mounted on the upper side of the support platform 2, the support platform 2 supporting the geared disc 3; and movable components on both sides of the upper surface of the geared disc 3, each movable component including an L-shaped rod 4 symmetrically arranged about the geared disc 3 and movable on the geared disc 3, thereby facilitating material handling and feeding. The material is fed out. The top of the L-shaped rod 4 is fixedly connected to the non-output end of the electric cylinder 5. The output end of the electric cylinder 5 is fixedly connected to the U-shaped frame 6. A small motor 7 is fixedly installed inside the U-shaped frame 6. The small motor 7 is electrically connected to the external terminal control equipment. A clamping component is provided at the output end of the small motor 7. The U-shaped frame 6 supports the small motor 7 and the clamping component. The clamping component is used to clamp the material. A pushing component is provided on one side of the bottom of the punch press body 1. A collecting component is provided on the other side of the bottom of the punch press body 1. A conveying component is provided on the side of the support table 2 away from the punch press body 1.

[0025] During processing, materials are conveyed via a conveying assembly. When the material is conveyed to the clamping assembly near the conveying assembly, the output end of the electric cylinder 5 on that side extends, causing the U-shaped frame 6 to move downwards, bringing the clamping assembly closer to the material. Then, the small motor 7 starts, causing the clamping assembly to clamp the material. After clamping, the clamping assembly on the other side simultaneously places the material. Then, the electric cylinder 5 starts in the reverse direction, moving the two symmetrically arranged L-shaped rods 4 in the moving assembly towards each other. Then, by controlling the rotation of the gear plate 3, the clamping assembly on the side holding the material rotates to the side of the punch press body 1, while the clamping assembly not holding the material rotates to the side of the conveying assembly. Then, the output end of the electric cylinder 5 extends again, and the two L-shaped rods 4 move in opposite directions, thus clamping the material on one side. The clamping assembly on one side places the material on the press body 1, while the clamping assembly on the other side, which does not clamp the material, clamps the material on the conveying assembly. Then, the electric cylinder 5 and the two L-shaped rods 4 are driven in reverse, causing the gear plate 3 to rotate. During the rotation of the gear plate 3, the press body 1 performs stamping processing. After processing, the workpiece is pushed out by the push-pull assembly and collected by the collecting assembly until the clamping assembly rotates to the underside of the press head again. This process is repeated to achieve automated feeding. The entire process is controlled by the control system. The worker only needs to place the material to be processed on the material conveying assembly, without having to manually place the material on the press body 1, and without having to manually remove the processed material. This reduces the operational risks of manual feeding and unloading, and improves production efficiency.

[0026] Example 2: Based on Example 1, a large motor 8 is fixedly installed on the lower surface of the support platform 2. The large motor 8 is electrically connected to an external terminal control device. The output end of the large motor 8 passes through the support platform 2 and is fixedly connected to one end of the connecting shaft 9. A small gear 10 is fixedly sleeved on the other end of the connecting shaft 9. Thus, the connecting shaft 9 is rotated by the large motor 8, and the connecting shaft 9 drives the small gear 10 to rotate. One side of the small gear 10 meshes with the gear disc 3 for transmission. The gear disc 3 is rotated and sleeved on the fixed column 11. The fixed column 11 limits the position of the gear disc 3. The bottom of the fixed column 11 is fixedly connected to the support platform 2, and the lower surface of the gear plate 3 is slidably connected to the upper surface of the support platform 2. The moving component also includes a dual-axis motor 12 set on the upper side of the fixed column 11. The dual-axis motor 12 is electrically connected to an external terminal control device. The two output ends of the dual-axis motor 12 are fixedly connected to threaded rods 13. The dual-axis motor 12 drives the threaded rods 13 to rotate. Four support seats 14 are fixedly connected to the upper surface of the gear plate 3. The ends of the threaded rods 13 are rotatably sleeved in the support seats 14. The support seats 14 limit the threaded rods 13.

[0027] The bottom of the dual-axis motor 12 is fixedly connected to the two support seats 14 near the fixed column 11 via a horizontal plate. The horizontal plate provides fixed support for the dual-axis motor 12. A movable block 15 is threaded onto the threaded rod 13. Sliding rods 16 are slidably fitted at the four corners of the movable block 15. The sliding rods 16 limit the movement of the movable block 15. Both ends of the sliding rods 16 are fixedly connected to the support seats 14. The upper surface of the movable block 15 is fixedly connected to the bottom end of the L-shaped rod 4.

[0028] The clamping assembly includes grippers 17 symmetrically arranged about the bottom of the U-shaped frame 6. The grippers 17 clamp the material by opening and closing. One end of the grippers 17 is rotatably connected to the connecting plate 18 by a large pin. The other end of the connecting plate 18 is rotatably connected to the U-shaped frame 6 by a small pin. A toothed rod 19 is provided on one side of the connecting plate 18. The toothed end of the toothed rod 19 is an incomplete gear. The toothed rods 19 are symmetrically arranged about the bottom of the U-shaped frame 6. One end of each of the two toothed rods 19 is rotatably connected to the grippers 17 by a large pin. The other end of one toothed rod 19 is rotatably connected to the U-shaped frame 6 by a large pin. The other end of the other toothed rod 19 is fixedly connected to the output end of the small motor 7 through a connecting block 20. The toothed ends of the two toothed rods 19 mesh and drive each other.

[0029] When workpieces need to be loaded, the material is conveyed to one side of the loading component by the conveying component. The dual-axis motor 12 is then started via an external control device, causing the threaded rod 13 to rotate under the limit of the support seat 14. This causes the moving block 15 to move along the axis of the threaded rod 13 under the limit of the slide rod 16, and in the opposite direction away from the fixed column 11. The moving block 15 then synchronously drives the L-shaped rods 4 to move synchronously. One L-shaped rod 4 drives one side of the clamping component closer to the material, while the other L-shaped rod 4 moves closer to the punch press. Then, the electric cylinder 5 is started, causing the U-shaped frame 6 to approach the material. Next, the small motor 7 on that side is started via the external control device. The small motor 7, connected by the connecting block 20, drives one of the toothed rods 19 to rotate, causing the other toothed rod 19 to move synchronously through meshing. The other toothed rod 19 rotates under the rotational engagement of the large pin and the U-shaped frame 6, thus connecting the two toothed rods 19 through the rotation of the small pin. The movement of the gripper 17 is driven by the rotational connection between the connecting plate 18, the small pin, the large pin, and the U-shaped frame 6. This allows the gripper 17 near the material to clamp the material, while the gripper 17 near the press body 1 opens to place the material. After clamping and placing, the small motor 7, the electric cylinder 5, and the dual-axis motor 12 are controlled to move in opposite directions. Then, the large motor 8 is started by the external control device, which drives the small gear 10 to rotate through the connecting shaft 9. The small gear 10 then meshes with the gear plate 3. The gear plate 3 rotates 90 degrees under the limit of the fixed column 11. At this time, the press body 1 performs stamping processing on the material. Then, the small gear 10 drives the gear plate 3 to rotate 90 degrees again, thereby exchanging the positions of the two clamping components. This allows for reloading and reunloading of the material. This process repeats, achieving automatic feeding, avoiding the trouble and danger of manual feeding, and improving processing efficiency and safety.

[0030] Example 3: Based on Example 2, the pushing assembly includes an electric push rod 21, which is electrically connected to an external control device. The output end of the electric push rod 21 is fixedly connected to a pushing plate 22. The collecting assembly includes a guide plate 23 and a collecting box 24. The top of the guide plate 23 is fixedly installed on one side of the processing table of the punch press body 1. The conveying assembly includes a belt conveyor 25 and a photoelectric sensor 26 installed on one side of the belt conveyor 25. The photoelectric sensor 26 includes a photoelectric transmitter and a photoelectric receiver.

[0031] During processing, the operator places the material on the belt conveyor 25. When the material to be processed is conveyed to the photoelectric sensor 26, it is positioned between the photoelectric transmitter and the photoelectric receiver. At this time, the light beam emitted from the photoelectric transmitter is blocked. After the photoelectric receiver detects that the light beam is blocked, it generates an electrical signal change, such as changing from a high level to a low level or vice versa. This signal is transmitted to the external controller, which then controls the belt conveyor 25 to stop, thereby facilitating the clamping assembly to grip the material. After the material processing is completed, the electric push rod 21 is fixedly installed on the side of the punch press body 1 near the processing table. The electric push rod 21 is driven by an external control device to extend its output end, thereby driving the pusher plate 22 to push the material out of the processing table. Then, the material is guided by the guide plate 23 to slide into the collection box 24 for collection. This eliminates the need for workers to manually remove the processed material, avoiding the risks associated with manual material removal. Furthermore, the external control device controls the electric push rod 21 to push the material out, ensuring a smooth overall process during material removal. This improves production efficiency compared to manual material removal. In addition, the guide plate 23 and the collection box 24 eliminate the hassle of manually collecting the processed material.
