Roller mold for processing seamless steel cylinder

Abstract

The invention relates to a roller die for processing a seamless steel bottle body which belongs to the technical field of manufacture of high pressure vessel processing equipment. The roller die mainly consists of a roller die frame (1), five to eight uniformly distributed rollers (2) which are arranged in the roller die frame (1), etc. In order to solve the problem that the quality of the outer surface of the seamless steel bottle body which is processed by the existing roller die only provided with four rollers is poor, a structure form that five to eight rollers are uniformly distributed and arranged in the roller die frame is adopted, which ensures that the arched contact surface of the rollers is more approximate to the standard outer diameter of the seamless steel bottle body; simultaneously, the roller die is concerned with the rolling of the seamless steel bottle body, thereby improving the quality of the outer surface, the circular degree and the wall thickness uniformity of the seamless steel bottle body.

Description

technical field [0001] The invention relates to a roll mold for processing a seamless steel cylinder body, belonging to the technical field of manufacturing high-pressure container processing equipment. Background technique [0002] At present, the known technological process of making a seamless steel cylinder body with a steel billet is to heat the steel billet, put it into the die of a punching hydraulic press, use the back extrusion method to form the billet into a cup-shaped punching billet in the die, and then Immediately put the punched blank into the receiving table of the drawing press, insert the ejector pin of the drawing press into the punching blank, and install the drawing formwork and unloading device on the front beam of the drawing press, which can be separated Four ring dies and roll dies are placed, and the ejector rod with the punched billet is pushed by the main water cylinder, so that the punched billet passes through the ring die and roll die quickly, ...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the existing problems such as the poor quality of the external surface of the seamless steel cylinder processed by the roll mold with only four rolls, and adopts a structural form in which 5 to 8 rolls are evenly distributed in the roll mold base, so that the arc shape of the rolls is The contact surface is closer to the standard outer diameter of the seamless steel cylinder body, and at the same time participates in the rolling of the seamless steel cylinder body, which effectively improves the outer surface quality, roundness and wall thickness uniformity of the seamless steel cylinder body
