Description

Technical Field

[0001] This utility model relates to the field of punch press processing, specifically a punch press with an auxiliary feeding mechanism. Background Technology

[0002] In the fields of national production such as automobile manufacturing, electronic components, and hardware processing, stamping has become a core processing method due to its significant advantages. Compared with traditional machining, stamping uses molds to apply pressure to metal or non-metal sheets to achieve shaping. With the help of complex molds, it is possible to produce irregularly shaped parts that are difficult to achieve by machining (such as automobile body panels and electronic component springs). It has lower technical requirements for operators and is therefore widely used in the mass production of standardized products, supporting the efficient operation of the industrial sector. As the core equipment for realizing the stamping process, the operating efficiency and safety of the punch press directly affect the production quality and personnel safety. Currently, mainstream punch presses have two major defects in practical applications, which seriously restrict production efficiency and safety assurance. On the one hand, the loading of materials relies on manual operation, which is inefficient and unsafe. Currently, the loading of materials on punch presses is mostly done by operators manually moving the plate to the die station, then manually adjusting the position and fixing it. When loading materials manually, the operator's hands need to be close to the dangerous area of ​​the die (within the stamping stroke range). If the equipment's protective device responds late or there is an operational error, it is easy to cause safety accidents such as punching injuries and crushing injuries. On the other hand, the lack of protective measures during the stamping process poses multiple safety hazards. Most existing punch presses only have simple metal baffles on both sides of the die, lacking comprehensive protective design. During stamping, the plate is prone to generating metal chips under high pressure (especially in thin plate stamping). The chips fly at high speed, which not only pollutes the production environment but may also scratch the skin and damage the eyes of operators. At the same time, dust, lint and other foreign objects in the production workshop can easily enter the dangerous area of ​​the die through the gaps in the baffles, causing the die to jam or be damaged, affecting the stamping accuracy.

[0003] The existing punch presses in industrial production suffer from efficiency bottlenecks and safety risks due to manual feeding, as well as production hazards caused by lack of protection. These issues are no longer suitable for the requirements of modern production for high efficiency, safety, and stability. In fact, frequent accidents increase the operating costs of enterprises. Therefore, it is necessary to design a punch press with an auxiliary feeding mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a punch press with an auxiliary feeding mechanism to solve the problems mentioned in the background art.

[0019] Specifically, the support includes three sliders 10 arranged circumferentially on the top of the mounting box 2 by bolts. The top of the sliders 10 is screwed with a mounting rod 11. A support plate 12 for supporting the plate to be processed is fitted on the outside of the mounting rod 11. A support frame 13 is bolted to the top of the mounting box 2 and near the other side. A first motor 14 is installed at the bottom of the support frame 13. A first lead screw 15 is installed on the top of the first motor 14. A support block 16 is fitted on the outside of the first lead screw 15. The support block 16 is bolted to the support plate 12. The support also includes a support rod 17 bolted to one side of the mounting box 2 and near the top. A pad 18 is bolted to the top of the support rod 17.

[0020] The pad 18 installed on the top of the support rod 17 can support the plate to be processed, and the support plate 12 on the outside of the mounting rod 11 can support multiple spare plates upward. The first motor 14 drives the support plate 12 on one side of the support block 16 to move upward through the first lead screw 15. When the spare plate is removed, the support plate 12 supports the remaining spare plates to move upward, so that the gripper can simultaneously grip the plate to be processed and place it on the top of the pad 7 and grip the spare plates and place them on the pad 18, thereby improving the convenience and stability of the gripper in transferring and picking up the plates.

[0021] More specifically, the gripping component includes a second lead screw 19 that passes through the crossbeam 9. A second motor 20 is installed at one end of the crossbeam 9 and at the end of the second lead screw 19. A sliding frame 21 is fitted on the outside of the second lead screw 19.

Then, the hydraulic rod 23 drives the drive frame 22 to slide up and down on one side of the sliding frame 21. At the same time, the two fixing bars 30 guide and limit the drive frame 22. Then, the drive frame 22 drives the two gripping discs 24 to move up and down via the cross bar 221. Then, the pneumatic suction cups 25 of the gripping discs 24 pick up the spare plate for transfer and placement. Restart cylinder 3, causing it to move connecting block 5 up and down via push rod 4. Then, connecting block 5 moves protective cover 28 down via fixed rod 501. At the same time, connecting block 5 drives stamping block 6 to stamp the workpiece on top of pad block 7. Meanwhile, protective cover 28 slides relative to fixed rod 501, so that protective cover 28 protects against flying debris.
