Continuous punching die for automobile supporting frame

Abstract

The invention provides a continuous punching die for an automobile supporting frame. The continuous punching die for the automobile supporting frame comprises an upper die body and a lower die body. The lower die body comprises a lower die seat and a lower pressing plate arranged in the lower die seat. A conveying mechanism is arranged at one end of the lower die seat. The lower pressing plate is provided with positioning holes, irregular-shaped grooves, conveying positioning blocks and a lower convex block, the multiple positioning holes are arranged at equal intervals in the conveying direction, and the multiple irregular-shaped grooves are distributed in the two sides of the positioning holes. The upper die body comprises an upper die seat and an upper pressing plate. The upper pressing plate is provided with positioning pillars corresponding to the positioning holes and an upper convex block matched with the lower convex block. The upper die seat is provided with positioning punches corresponding to the positioning holes and punches corresponding to the irregular-shaped grooves, and the positioning punches and the punches can penetrate through the upper pressing plate. The continuous punching die for the automobile supporting frame can complete punching work on the automobile supporting frame, is high in punching accuracy, reduces manpower and material resources, lowers the reject ratio and effectively improves the quality of products and production efficiency.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold for continuous punching of automobile brackets. Background technique [0002] As one of the important parts of the car, the car bracket has been more and more widely used, but the traditional car bracket is usually processed through multiple matching molds. After a process is not completed, the mold needs to be replaced. The processing of the next process is cumbersome and requires a lot of manpower, resulting in low production efficiency. Moreover, for the situation that there are many holes on the car bracket, one-time punching often causes deformation of other parts, and the product failure rate is high, which affects the quality of the product and increases the cost. Contents of the invention [0003] In view of the above defects in the prior art, the problem to be solved by the present invention is to provide a continuous automobile bracket that can complete the punc...
