Edge cutting device and method for end socket without turnup

Abstract

The invention relates to an end socket edge cutting device and method, in particular to an edge cutting device and method for an end socket without a turnup. The technical problems that the quality of a produced end socket is difficult to meet the technical requirement and the production efficiency is low as the edge cutting height of the end socket cannot be accurately determined in the conventional edge cutting device and method for the end socket without the turnup are solved. The edge cutting device comprises an automatic centering end socket male die, an end socket inner surface edge cutting and scribing tool and an end socket inner surface line-to-outer surface line tool, and the technical problem that the edge of the end socket without the turnup cannot be accurately cut is thoroughly solved through cooperative use of the three tools. According to the edge cutting device for the end socket without the turnup, the blanking size of an end socket blank is reduced through the edge cutting process, the end socket manufacturing cost is reduced, and the market competitiveness of end socket manufacturers is improved. The edge cutting method is carried out through the device, operation is convenient, the edge cutting efficiency of the end socket without the turnup is improved, the edge cutting quality is guaranteed, and the quality requirements for machining of normal-pressure and pressure vessel end sockets can be met at the same time.

Description

technical field [0001] The invention relates to a head edge cutting device and method, in particular to a head edge cutting device and method without flanging. Background technique [0002] At present, the manufacturers of the head, especially the manufacturers of the pressure vessel head, usually use the forming mold with flanging in order to ensure the height of the cutting edge when designing the head forming mold. When cutting the edge, the arc at the flanging is taken as The cutting edge is carried out according to the benchmark, and this scheme can accurately determine the cutting edge height of the head. However, there is a problem: because the head has flanging during processing, the flanging needs to be cut off when cutting the edge, resulting in serious waste of raw materials and greatly increasing the manufacturing cost of the head. Among the existing atmospheric pressure head manufacturers, very few use the head forming process without flanging, but because the ...
