Cold drawing equipment for stainless steel product machining

Abstract

The invention belongs to the technical field of stainless steel product machining, and particularly relates to cold drawing equipment for stainless steel product machining. According to the scheme, the cold drawing equipment comprises an operation table and a fixing rod, and a pre-cold-drawing mold is fixedly connected to the outer wall of the bottom of the fixing rod. According to the cold drawing equipment for stainless steel product machining, through the arrangement of a molding cover, sliding blocks, hydraulic cylinders and molding plates, a guide groove is formed in the inner wall of the molding cover, in the pre-cold-drawing process of a stainless steel product, the hydraulic cylinders are adjusted to drive the molding plates to make contact with the outer wall of the stainless steel product, in the process of sliding on the outer wall of the stainless steel product along with the pre-cold-drawing mold, the molding plates extrude the stainless steel product, the cold-drawn stainless steel product is easy to deform, the outer wall of the stainless steel product is polished and molded through the molding plates, the situation that the outer wall of the stainless steel product is uneven is prevented, and in the process that the molding plates and the stainless steel product are mutually extruded, the sliding blocks slide in the guide groove, so that the molding plates realize self-rotation, and the molding effect on the stainless steel product is improved.

Description

technical field [0001] The invention relates to the technical field of processing stainless steel products, in particular to a cold drawing equipment used for processing stainless steel products. Background technique [0002] Cold drawing is a kind of processing technology for materials. For metal materials, cold drawing refers to drawing under the condition that the material is at normal temperature in order to achieve a certain shape and certain mechanical properties; cold drawn products are compared with Thermoforming has the advantages of high dimensional accuracy and good surface finish; according to the temperature of the metal during drawing, drawing below the recrystallization temperature is cold drawing, and drawing above the recrystallization temperature is hot drawing; cold drawing is The most common drawing method used in metal wire and wire production. When hot drawing, the metal wire must be heated before entering the die hole. It is mainly used for drawing hig...

AI Technical Summary

Problems solved by technology

[0003] When the existing stainless steel products are processed, they need to be stretched by cold drawing equipment. The existing cold drawing equipment generally cools the stainless steel products, and then pulls them through the cold drawing die to realize the cold drawing of the stainless steel products. This cold drawing method is easy to cause fatal damage to stainless steel. The diameter difference between the cooled stainless steel product and the cold drawing die is large, and it is directly and forcibly drawn through the cold drawing die. During the forced drawing process, The deformation of stainless steel products is relatively large, which may directly cause damage to the internal structure of the stainless steel product, resulting in the lack of toughness of the stretched stainless steel product and loss of its use value, resulting in the lack of use value of the cold drawing equipment
