Automobile swing arm trimming die

Abstract

The invention provides an automobile swing arm trimming die, which comprises an upper die part and a lower die part. The upper die part comprises an upper die swinging ring component, a guide sleeve fixing base, a guide sleeve, an upper limiting component, a pressing block, a lifting spring, a socket head cap screw, a female die base plate, an upper die holder, a female die frame, a female die insert component, a hexagon socket screw and a positioning pin; and the lower die part comprises a workpiece positioning block, a male die insert component, a male die base plate, a male die fixing plate, a hexagon socket screw, a positioning pin, a lower die plate, a supporting plate, a lower die holder, a lower limiting component, a lower die swinging ring component, a guide column fixing base, a guide column, a discharging spring, a discharging plate and a discharging screw. According to the automobile swing arm trimming die provided by the invention, the trimming processing of the workpieces in different specifications and sizes can be realized through only replacing the components; and the automobile swing arm trimming die is simple in structure, convenient to operate, low in manufacturing cost, excellent in size uniformity after processing, and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical processing cold stamping, in particular to an automobile swing arm trimming die. Background technique [0002] The swing arm is the main part of the front suspension part of the front frame of the automobile chassis. It is used to connect the body and the frame, so the matching accuracy is high. At present, the swing arm is usually processed by milling or wire cutting. The thickness of the arm material is relatively thin, the burrs after processing are large, the workpiece is easily deformed, and the dimensional consistency after processing is not high, which cannot match the matching parts, which affects the subsequent welding process and assembly process, and cannot reach Due to the technical requirements of the process, the waste of materials is large, the production efficiency is low, and the production cost is high. Contents of the invention [0003] The purpose of the present invention...
