Stamping die for automobile chassis

Abstract

The invention relates to an automobile die, in particular to a stamping die for an automobile chassis. The stamping die comprises an upper die holder, an upper die body, a lower die body, a lower die holder, four forming positioning columns and ejecting air cylinders; the upper die body is fixed to a forming cushion plate, the forming cushion plate is fixed to the upper die holder, the lower die body is installed on the lower die holder, the upper die body is provided with a stamping head and a drawing stamping head, and the lower die body is provided with a tool edge and a drawing cavity; the four forming positioning columns are fixed the lower die body, penetrate through the lower die body and are symmetrically distributed on the two sides of the lower die body, the distance between every two adjacent forming positioning columns is smaller than the width of a material band, one end of each ejecting air cylinder is fixed to the lower die holder, the other ends of the ejecting air cylinders are located under the material band, and when the air cylinders retract, the ends of piston rods do not go beyond the upper surface of the lower die body. The stamping die for the automobile chassis has the advantages of being convenient to maintain, simple and stable in structure, low in production cost and capable of achieving precise positioning and the good forming effect on the condition that the product precision requirement is high while the die surface is complex.

Description

technical field [0001] The invention relates to an automobile mold, in particular to a stamping mold for an automobile chassis. Background technique [0002] The chassis of the car is a very important part when the car is running, and this part not only plays the role of the bracket of the whole car during work, but also can play the role of stabilizing the car when the car is running. The car chassis is composed of multiple car stamping parts, and the whole chassis can complete the work of the car's transmission system, driving system, steering system and braking system. In addition, during the installation of the chassis, in addition to supporting and installing the engine, it can also achieve the effect of supporting and installing other parts and assemblies in the car. In the process of designing the car, the chassis can play the role of forming the overall shape of the car In addition, in sports, the power output by the engine and the safe driving of the car are also o...

AI Technical Summary

Problems solved by technology

[0004] When processing automobile chassis, the automobile chassis needs to go through many stamping processes. In the existing process of processing automobile chassis, it needs to go through four processes of rough trimming, stretch stamping, hole stamping and fine trimming. The first process uses a stamping die. After one stamping process is completed, the next stamping process is carried out sequentially until all stamping processes are completed. Such a stamping process is labor-intensive, time-consuming, laborious, and low in efficiency. Equipped with multiple stamping dies, the production and processing costs are relatively high, and the positioning accuracy of the die itself is not high. After using multiple dies, the position of the parts processed is easy to deviate, and the scrap rate is high
