Side-forming small pressure core, stamping mould with same and stamping method

Abstract

The invention discloses a side-forming small pressure core, a stamping mould with the same and a stamping method. The side-forming small pressure core comprises a rotary shaft, a mount, an inclined guide plate, a cushion and a rotary loose piece, the cross section of the mount is U-shaped, one end of the rotary loose piece is fixed in a U-shaped opening of the mount through the rotary shaft, the rotary loose piece rotates around the rotary shaft, the inclined guide plate is arranged on the side of the movable loose piece parallel to the rotary shaft, the cushion used for debugging in mounting is mounted on the rotary loose piece and located right below the inclined guide plate, and a main pressure core is provided with a return spring providing return force to the rotary loose piece. The side-forming small pressure core capable of rotating is simple in operation, and has lower requirements for unidirectional portions as compared with a self-made wedge mechanism with a pressure core and a reshaping tool block integrated, so that the self-made wedge mechanism with the pressure core and the reshaping tool block integrated is simplified, the space occupied by the small side core is quite small, and various components of the integral mould is more compact in arrangement.

Description

Technical field [0001] The present invention relates to the field of automobile cover molds, in particular to a rotary pressing core mechanism and a set of automobile cover stamping molds and a stamping method using the mechanism. Background technique [0002] In recent years, with the continuous development of the manufacturing industry, the pursuit of product quality and the saving of manufacturing costs have become two major concerns of enterprises. Due to the complex surface modeling of the car body, there are many differences in the orientation of the holes and edges on the top. In some forming areas with negative angles and small areas, a special pressing process is sometimes required. How to design a pressing device to meet the pressure Material requirements and optimization of mold structure have always been a difficult problem in current design. [0003] At present, when designing automobile stamping dies, the forming parts that require lateral pressing are generally real...

AI Technical Summary

Problems solved by technology

In order to consider the orientation of the side pressure core and the arrangement of the pressure source, the volume of the designed first slider is more than ten times that of the actual work, resulting in a lot of material waste, and increasing the complexity of the structure and the difficulty of fitter debugging. The material effect can not meet the ideal requirements

At the same time, this type of mechanism involves a lot of content, so the manufacturing process is complicated. It is not only unsightly in the mold with a large surface drop, but also greatly affects the smooth pick-up.
