Description

Technical Field

Background

The press forming die is a process equipment for press forming, which is a tool for separating or plastically deforming a material by applying pressure to the material using a die mounted on a press machine, thereby obtaining a part of a desired shape and size, and its working principle is based on the basic principle of press forming, and the material is deformed to be expected by the pressure by the specific shape and structure of the die, for example, in the manufacture of automobiles, many metal parts such as a car body panel, a car door, a bracket, etc. are manufactured by the press forming die. Generally consists of an upper die and a lower die,

However, in conventional carrier stamping dies, the movement of the carrier and the stamping process tend to be relatively independent. For example, the bracket may be first placed in a mold for stamping, then manually removed and moved to the next processing location after completion, or moved using a simpler mechanical device, but it is difficult to achieve an exact fit with the stamping action. This results in failure to perform punching operations such as surface notching at the same time in the moving process of the support, which reduces the processing efficiency and makes it difficult to ensure the processing accuracy. Because the position of the bracket may deviate during multiple manual interventions or imprecise movements, affecting the quality of the stamping.

It is necessary to provide a bracket press forming die to solve the above-mentioned problems.
