Machining jig of circular nonstandard punch for automobile punching die

Abstract

The invention discloses a processing jig for circular non-standard punches of automobile stamping dies, which consists of a jig body, a V-shaped slider, a V-shaped pressing block, a backer and a punch, and the jig body is connected to the backer ; The V-shaped pressing block is matched with the V-shaped slider and the slope of the backing; the punch is placed between the jig body and the V-shaped slider. The backing and the jig body are fixed with positioning keys and locked with bolts. A spring is arranged under the V-shaped pressing block, and the spring and the V-shaped pressing block are connected to the jig body through the cooperation of the bolt and the T-shaped nut. In the present invention, the horizontal pushing type clamping is converted into oblique downward pressing, and when the screw locks the pressing block, a forward and downward force is provided to the pushing block, and the backing is stable. Through the conversion of the force direction, the accuracy and stability of the circular non-standard punch clamping are greatly improved. It can effectively increase the clamping force and stability, reduce processing tremor, improve clamping accuracy and processing accuracy, simplify operation and improve efficiency.

Description

technical field [0001] The invention relates to an automobile stamping die, in particular to a processing jig for a round non-standard punch of the automobile stamping die. technical background [0002] Under the background of the continuous development of modern science and technology and the rapid progress of mechanized forming technology, stamping technology in the modern sense is bound to show a very significant and vigorous development trend. The development of stamping technology presents a very prominent trend of integration, synthesis, intelligence and compounding. With the popularity of automobiles and the intensification of competition among automobile companies, the requirements for mold processing accuracy and production cycle are becoming more and more stringent, especially for key parts of molds, such as round non-standard punches. The existing circular non-standard punch processing fixtures generally adopt the flat push type, which cannot guarantee the accura...

AI Technical Summary

Problems solved by technology

The existing circular non-standard punch processing fixtures generally adopt the flat push type, which cannot guarantee the accuracy and clamping force, the orientation is not accurate, and the clamping is cumbersome.
