Automobile trimming and punching die with material pressing cores

Abstract

The invention discloses an automobile trimming and punching die with material pressing cores. The automobile trimming and punching die comprises an upper die seat and a lower die seat. A first sliding groove is formed in the bottom end of the upper die seat. Telescopic rods are arranged on the two sides in the first sliding groove. Clamping blocks are mounted on the two sides of the bottom end of each telescopic rod. Second sliding grooves are formed in the two sides of the first sliding groove. The first sliding groove is in vertical cross connection with the second sliding grooves. One trimming material pressing core is arranged in each second sliding groove. A puncher pin seat is arranged between the trimming material pressing cores. The punching material pressing core is arranged on the side, close to the lower die seat, of the puncher pin seat. A puncher pin is arranged in the punching material pressing core in a sleeved manner. Drive rods are arranged on the two sides of the top end of the lower die seat. The output ends of the drive rods are connected with a discharging plate. Supporting columns are arranged between the drive rods. According to the automobile trimming and punching die, the cost of the die is effectively reduced; the situation that the service life of the die is influenced due to overexertion of the upper die seat is avoided, and machining precision and work efficiency are improved; and the phenomenon that the upper die seat rebounds during work is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to an automobile trimming and punching die with a pressing core. Background technique [0002] Die design and manufacturing technology is the core technology of modern stamping production. With the rapid development of modern manufacturing industry, the automobile industry is constantly pursuing efficient, safe and reliable production. Usually, for automobile panels, after stretch forming, the subsequent trimming, punching and separation need to be completed in two steps. The stamping parts to be trimmed have complex shapes, and the position of the mold separation edge may be arbitrary. Space surface, stamping parts usually have different degrees of elastic deformation, and there is usually a large lateral pressure in the separation process. Therefore, when designing the mold, issues such as stamping direction, part positioning, mold guiding, waste removal, workpiece removal, and late...

AI Technical Summary

Problems solved by technology

At present, most of the side trimming and punching dies for automobiles have complex structures and low precision of punching holes. In addition, two sets of dies are required to complete the trimming and punching processes when processing some automobile parts. On the one hand, the price and cost of the dies Increase, on the other hand, the position of punching is fixed, and unloading is troublesome. At the same time, trimming and punching are only performed on specific types of auto parts, which seriously affects the improvement of output and work efficiency, and there are certain restrictions on use.
