Solid particle medium forming method and equipment

Abstract

The invention discloses a solid particle medium forming method and equipment. The method comprises the following steps: firstly smearing a lubricant on the upper surface and the lower surface of a plate, placing the plate on the forming equipment for forming after the lubricant is aired, adopting a solid particle medium to provide a load for the deformation of the plate, providing constraint and shape required by the forming of the plate by an embedded female die, and completing plate forming through the forming equipment. According to the solid particle medium forming method and equipment, the plate forming performance can be effectively improved, the die structure is simple and easy to replace, the part forming quality is good, and the problem that sealing is difficult in the forming processes such as liquid filling and air expansion is solved; the plate forming performance can be effectively improved; the die is simple in structure and low in manufacturing cost; and solid particles are harmless to human bodies, free of pollution to the environment, and can be recycled.

Description

technical field [0001] The invention relates to the field of precision forming manufacturing, in particular to a solid particle medium forming method and equipment. Background technique [0002] With the continuous development of science and technology and industrial production, automobile lightweight has become the development trend of the world automobile industry. In recent years, domestic automobile companies have generally adopted high-strength steel plates. However, high-strength steel plates are prone to wrinkling and cracking during forming. In addition, as the strength of the material increases, the amount of springback will increase accordingly. In response to these problems, researchers have proposed soft molding technology. Soft mold forming is to use a certain material instead of a rigid punch or die as the force transmission medium for sheet metal forming, and then use a rigid mold as a die or punch to make the sheet and punch or die The molded surfaces fit ...

AI Technical Summary

Problems solved by technology

For example, the leakage of hydraulic oil will pollute the environment; the life of the rubber is short and the moldability is poor in the fillet area of ​​the mold; the viscous medium also needs good sealing and the cost is high, etc.

These deficiencies limit the further development and application of this technology to some extent
