Stamping die and stamping method using same

Abstract

The invention discloses a stamping die and a stamping method using the same. The stamping die is provided with an upper die and a lower die, wherein a plurality of upper die blocks and a plurality of lower die blocks are correspondingly arranged on the upper die and the lower die respectively; the upper die blocks and the corresponding lower die blocks form die sets; the die sets comprise edge trimming die sets, a central die set and cutting-off die sets; the edge trimming die sets are positioned on two sides in the left-right direction; the central die set is positioned between the edge trimming die sets; the cutting-off die sets are positioned on two sides in the left-right direction; in front of the edge trimming die sets and the central die set, a right cutting blade of the cutting-off die set on the left side is positioned on the right side of a left cutting blade of the central die set, and a left cutting blade of the cutting-off die set on the right side is positioned on the left side of a right cutting blade of the central die set. Continuous plate stamping forming can be realized, plates are stamped by the die sets, plate deformation caused by the reason that forces applied to plates are uneven in one-time forming is avoided, meanwhile, by the arrangement mode of the die sets, the precision of stamping is high, errors cannot be caused at joints of various substeps, and therefore, stamping quality is ensured.

Description

technical field [0001] The invention relates to processing equipment and a processing method, in particular to a stamping die and a stamping method using the stamping die. Background technique [0002] In the process of automobile development, in order to improve the utilization rate of vehicle materials, some automobile stamping parts are obtained by purchasing strip-shaped plates and reasonably arranging them on the strip-shaped plates according to the shape of the part blanks to obtain part blanks. The blanks after blanking are stamped and formed to obtain parts. [0003] The part blanks are mainly stamped by the blanking punching die. In the stamping process, starting from one end of the strip-shaped plate, each punch can be stamped to form one or more part blanks. After each punch, the mold is opened and the The strip moves forward and is positioned for blanking at the next position. [0004] In the traditional stamping method, one or more parts are directly stamped o...

Problems solved by technology

[0004] In the traditional stamping method, one or more parts are directly stamped out with each sprint, which means that the mold performs stamping actions on the surrounding parts at the same time. Once the force is unbalanced, it is easy to deform the parts
