Stiffening beam-rear transverse beam trimming punching and forming combination structure

Abstract

The invention provides a stiffening beam-rear transverse beam trimming punching and forming combination structure. The structure comprises a lower mold plate, nitrogen springs and limiting screws. Thelower mold plate and an upper mold plate are buckled together. A material return plate is fixedly installed on the plane of the top of the lower mold plate. According to the stiffening beam-rear transverse beam trimming punching and forming combination structure, a mold structure with the diversified working procedure content is adopted, the outline appearance of the portion of the lower mold plate can be directly fed, trimmed and accomplished by the structure, the material return plate can directly push out blank waste materials, workers conveniently take the blank waste materials, the division of plate materials and product feeding parts is accomplished, and small holes formed in the bottom surface can be punched after trimming is accomplished. In the drawing 2, a small flanging male mold is processed to be a movable part, and the new technological development of the punching mold industry is also promoted. By means of the working procedure, the hole position deformation which is caused by material movement in the punching and forming process is avoided, and the requirement for the precision punching of the hole position in the follow-up process is met. In the current social form, the stiffening beam-rear transverse beam trimming punching and forming combination structure can completely maximize all resources.

Description

technical field [0001] The invention belongs to the technical field of moulds, and more specifically relates to a reinforcing beam-rear beam trimming, punching and forming composite structure. Background technique [0002] At present, with the development of science and technology, automobiles have been widely popularized. The components of the automobile body are generally made of sheet metal, and generally need to go through blanking, drawing, trimming, punching and other processes. The stamping process of turning the flat sheet into an open hollow part. During the deep drawing process, the blank holder of the current drawing die is installed on the edge part between the concave and convex dies to prevent the edge of the workpiece from being unstable and wrinkled. The graphic pressing device, trimming refers to the stamping process in which the supplementary part of the process added around the stamped part and the supplementary part of the process added inside the stamped...
