Trimming-first and flanging-second mold with pressing function for complex curved surface of lightweight material

Abstract

The invention aims to provide a trimming-first and flanging-second mold with a pressing function for a complex curved surface of a lightweight material. A lower mold trimming knife block is installedon a lower mold body as a lower mold cutting edge part; a safety bolt, a side pin and a side pin clamping plate component are installed on an upper mold trimming and flanging knife block, and are thenintegrally installed on an upper mold body to form an upper mold cutting edge part; a guide plate is installed on a trimming and flanging small movable core as a small pressing core; an elastic ejector pin is installed on the upper mold body to provide a pressure source for the small pressing core; and when the mold is in work, a small pressing core is additionally provided to additionally provide a function of pressing before trimming, thereby achieving the effect of improving the product quality. The trimming effect of a product is improved; the product quality is improved; loss is reduced;the cost is lowered; and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold stamping dies, in particular to a die with the function of trimming first and then flanging, which has a complex curved surface of lightweight materials and has a pressing function. Background technique [0002] Driven by the market, all enterprises are focusing on energy saving and cost reduction, lean production management mode, and the effect of reducing stamping die process to achieve energy saving and cost reduction is very significant. Due to the limited stamping process, local trimming and flanging are carried out at the same time. There is no pressing device, and air cutting is performed directly, resulting in irregular cuts, product damage, and even product failure. The manufacturing cost of the car. [0003] Therefore, it is particularly necessary to design a binder structure with a simple structure to overcome the above-mentioned problem of trimming first and then flanging without binder....
