Problems solved by technology
[0002] In today's society, electronic products and ion products are becoming more and more intelligent and diversified. The quality of people's lifestyles is constantly improving, and the technical requirements and functionality of products are also increasing. The phenomenon of high rate, unable to meet the requirements for high-quality electronic products or ion products
[0003] In view of the common problems in the die-cutting processing industry at home and abroad, such as low repeated positioning accuracy of equipment, inaccurate positioning between subsequent die-cutting processing and previous processing, and unstable pressure of die-cutting processing equipment, it is necessary to provide a secondary positioning punch. Die cutting can improve the phenomenon of high defects caused by the offset of the current sleeve punching process, thereby reducing production difficulty, saving man-hours, and improving production efficiency

The invention discloses a secondary position punching die. The secondary position punching die comprises a first die body used for primary punching and a second die body used for secondary punching, and a linear semi-broken cutter structure is arranged on the first die body; the second die body is provided with a groove type cutter structure matched with the position of the linear semi-broken cutter structure, and a groove opening of the groove type cutter structure is consistent with the extending direction of the semi-broken cutter structure; and when the product punched by the first die body is secondarily punched by the second die body, a semi-broken cutter line formed by punching the product by the semi-broken cutter structure can pass through the groove of the groove type cutter structure. The sleeve position punching die has the advantages that by using the sleeve position punching die, the joint of primary punching and secondary punching can be in smooth contact, the purpose that a product body is not damaged when waste materials are torn off is achieved, the reject ratio is reduced, and working hours and manpower are greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of punching, and specifically relates to a secondary nesting punching die, which is suitable for products that require nesting punching and products with high body requirements after the waste is removed from the finished product. The stamping is convenient and simple, with high speed and low defect rate. Low, good stamping effect. Background technique [0002] In today's society, electronic products and ion products are becoming more and more intelligent and diversified. The quality of people's lifestyles is constantly improving, and the technical requirements and functionality of products are also increasing. The phenomenon of high rate cannot meet the requirements for high-quality electronic products or ion products. [0003] In view of the common problems in the die-cutting processing industry at home and abroad, such as low repeated positioning accuracy of equipment, inaccurate positioning between subs...
