Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing equipment, and in particular relates to sheet metal punching equipment for chassis production. Background Art

[0002] In the production process of electronic chassis, metal sheets are used as production raw materials. The purchased metal sheets are first cut into specifications and sizes that meet production requirements, and then the sheets that have completed the cutting operation are stamped and formed to form sheet metal parts. Then, multiple groups of sheet metal parts are fixedly connected using positioning tooling to form a chassis. In the process of sheet metal production and processing, it is necessary to punch holes in the sheet metal. The punching equipment in the prior art all has a punching structure fixedly installed on the upper template, and a punching hole corresponding to the position of the punching structure is fixedly set on the lower template. The sheet metal part is placed between the upper template and the lower template. When working, the upper template and the lower template are close to each other, and the punching structure cooperates with the punching hole to punch out corresponding holes in the sheet metal part.

[0003] However, in the actual working process, it was found that because the punching structure and punching holes in the above-mentioned punching equipment are fixed, it is difficult to adjust the position of the punching holes. When punching operations are required for sheet metal parts of different models, the upper template and the lower template need to be removed and adjusted to adjust the punching structure and the position of the punching holes. The operation process is cumbersome and the work efficiency is low. In addition, during the punching process, the sheet metal parts need to be positioned and fixed to avoid offset during the punching process and cause punching errors. However, most of the punching equipment on the market can only position and fix one type of sheet metal parts, with poor applicability, and cannot meet the needs of punching different types of sheet metal parts.
