Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to high-efficiency punching equipment for punching holes in sheet metal. Background Art

[0002] Sheet metal, a processing technology, can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets (usually less than 6mm), including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. For this reason, a high-efficiency punching equipment for sheet metal punching is proposed.

[0003] After searching, the Chinese patent with publication number "CN219357588U discloses a high-efficiency punching device for sheet metal punching, including a device body, a control component is installed inside the device body, a punching mechanism is installed on the top of the device body, and a protective component is covered on the surface of the punching mechanism. The utility model sets a control component to control the rotation of the screw so that the two moving blocks can respectively drive the pressing blocks to move toward each other to complete the clamping and fixing of the sheet metal plate. Synchronous control of the two pressing blocks to move toward each other can fix the sheet metal plate in the center position. The simple fixing operation also makes the punching processing accuracy of the sheet metal plate higher. The utility model sets an anti-slip component. Under the elastic force of the spring, the interception cover will always stick to the surface of the sheet metal plate during the punching process of the punching mechanism, so as to intercept the debris during the punching process to avoid accidental injury caused by the splash of debris, thereby making the processing and punching operation of the device safer. "However, the following deficiencies exist during use.

[0004] When punching a sheet metal part, the sheet metal plate to be processed is placed between two pressing blocks, and the screw is controlled to rotate by a handle. Under the meshing connection between the screw and the moving block, the side of the moving block is tightly fitted with the inner wall of the equipment body, so that the moving block can slide on the surface of the screw within a limited position. Since the threads on the two end surfaces of the screw are in opposite directions, the two moving blocks can respectively drive the pressing blocks to move toward each other to complete the clamping and fixing of the sheet metal plate, and then punch it. However, each time a hole is punched, the handle needs to be turned to control the rotation of the screw so that the pressing block clamps the sheet metal part, which is inconvenient to use for each punching and reduces the punching efficiency. Utility Model Content

[0005] The utility model aims to provide a high-efficiency punching device for sheet metal punching, so as to solve the problem proposed in the above background technology that when punching a sheet metal part, the sheet metal plate to be processed is placed between two pressing blocks, and the screw is rotated by controlling the handle.
