Mold for press forming small hole

Abstract

The invention provides a die used for punching small holes; the punching is completed on a guiding part of a fixed plate; the upper end of a punch is fixed on the fixed plate; the punch is arranged in an insert once guiding part arranged in a position limit plate and a stripper plate, and the punch end is arranged in an insert secondary guiding part; the punch end is matched with a concave template; strip material is arranged between the stripper plate and the concave template; the secondary guiding part ensures the punch to complete the punching successfully. The concrete die of the invention is provided with a plurality of punches; a group of small holes required by one product can be completed by carrying out the punching once; the small hole is the round hole with the diameter being 0.3mm or other smaller holes or ellipses or the holes with other shapes. The die of the invention greatly improves the working efficiency and reduces the production cost.

Description

Technical field: [0001] The invention belongs to a die for punching small holes in a punching die. Background technique; [0002] In the various earpieces used in daily life and industrial products that need to process small holes, due to the needs of transmitting sound waves or product design, because such products are generally formed on relatively thin metal materials, there must be a The process of processing small holes. The existing method of processing small holes is to place a template with holes on the material to be processed, and then use a high-speed drilling machine to drill holes one by one. This production method is not only costly, but also time-consuming and laborious. The quality of its drilling is also difficult to be guaranteed, so it needs to be improved. Invention content: [0003] The purpose of the present invention is to provide a punching die for punching small holes. [0004] The technical scheme of the present invention is as figure 1 As show...
