High-precision bending mold for side face punching

Abstract

The invention discloses a high-precision bending mold for side face punching. The bending mold comprises an upper die holder and a lower die holder which are correspondingly arranged, wherein the lower surface of the upper die holder is provided with a male die fixing block; an ejection device is arranged in the male die fixing block; the lower surface of the male die fixing block is provided with a male die; the male die is provided with a punching female die; the upper surface of the lower die holder is provided with a female die corresponding to the male die; a female die cavity is formed in the female die; the bottom of the female die cavity is fixedly provided with a punching male die corresponding to the punching female die; the lower die holder is provided with an ejection device. The bending mold has the advantages of rational design, simple structure, capabilities of improving the product quality of a bent part oblique surface punching and improving the productivity and convenience in generalization.

Description

technical field [0001] The invention relates to a bending die, in particular to a high-precision bending die for side punching. Background technique [0002] With the progress of society and the development of manufacturing industry, more and more mechanically processed products have entered people's daily life, and the bending parts punched on the bending surface are the most common, so how to improve the bending parts with holes Quality has become a difficult problem for producers to overcome. [0003] In the prior art, some bending parts punched on inclined planes have the above disadvantages. 1. Punching first before bending, this situation often causes deformation of the punching obtained before bending, and the punching cannot be fully obtained. 2. Bending first and then punching, this situation often leads to inaccurate positioning of punching holes on the bending slope, resulting in reduced matching accuracy and scrapping; 3. Whether it is punching first and then be...

[0003] In the prior art, some bending parts punched on inclined planes have the above disadvantages. 1. Punching first before bending, this situation often causes the punching obtained before bending to be deformed, and the punching cannot be fully obtained. 2. Bending first and then punching, this situation often leads to inaccurate positioning of punching holes on the bending slope, resulting in reduced matching accuracy and scrapping; 3. Whether it is punching first and then bending or first Bending and punching are all completed in different processes, which results in a reduction in production efficiency. In addition, it is easy to cause inaccurate positioning when changing stations, resulting in a reduction in the quality of bent parts
