Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for metal processing steel structures. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets.

[0003] The stamping process is a highly efficient processing method that can complete the production of a large number of products in a short period of time and improve production efficiency. During the stamping process, the mold can fix the shape of the product and maintain a certain processing force through pressure control, thereby ensuring the consistency and stability of the product and improving product quality.

[0004] The prior art patent document with publication number CN217990552U provides a metal processing stamping device, which arranges a fixed plate on the side of the lifting platform close to the operator and a protective structure on the side of the support platform close to the operator. When the lifting platform descends to perform the stamping operation, the fixed plate is driven down, and at the same time, the transmission gear is used to drive the frame and the protective plate in the protective structure to move upward, thereby separating the stamping area from the operator, thereby avoiding the problem that metal parts may collapse and debris may splash during the current metal processing and stamping operation, which may easily cause harm to the processing personnel.

[0005] In the above-mentioned prior art, although the stamping device uses a protective plate to prevent the metal parts from collapsing and causing debris to fly during the metal processing stamping operation, the stamping device in the patented technology does not limit and fix the workpiece during the stamping process. The workpiece may move during the stamping process, which will affect the stamping precision of the workpiece and reduce the stamping efficiency. Therefore, we need a stamping device for metal processing steel structures. Utility Model Content

[0030] Through the above technical scheme, the screw rod 302 can be manually rotated to drive the clamping plate 303 to move, and the two clamping plates 303 are moved inward to clamp and fix the two sides of the workpiece. The movable block 305 at the bottom of the clamping plate 303 can assist the movement of the clamping plate 303 to prevent the clamping plate 303 from rotating. In addition, during the stamping process of the stamping plate 7, the lower pressing plates 308 on both sides of the stamping plate 7 can press down and fix the top of the workpiece, thereby further improving the fixing effect of the workpiece and improving the precision during stamping.

During the stamping process, the lower pressure plate 308 will contact the top of the workpiece. As the stamping plate 7 descends, the lower pressure plate 308 will be compressed upward, and the workpiece is pressed down and fixed by the elastic force of the first spring 306, which further improves the fixation effect of the workpiece. While pressing, the stamping table 2 will move downward while applying pressure downward through the stamping plate 7.
