Abstract

The invention relates to an ultrahigh-pressure large end socket contour machining method. The ultrahigh-pressure large end socket contour machining method comprises the following steps that a steel plate is selected and cut to obtain material pieces, the material pieces are welded to form an assembly, the steel plate assembly is put in a heating furnace to be heated, the heated steel plate assembly is put into a large end socket spinning machine to conduct one-time spinning formation, groove cutting and nondestructive testing are conducted on the end socket obtained after the spinning formation is conducted, acid pickling passivating processing is conducted on the surface, and the end socket needing to be prepared is obtained after the prepared end socket passes testing. By means of the ultrahigh-pressure large end socket contour machining method, large end sockets with the diameters of 12 m or larger can be machined, the machining precision is high, and integrated formation is achieved.

Description

A kind of ultrahigh pressure large-scale seal head molding processing method
Technical field
The present invention relates to a kind of Manufacturing Technology of Back-Covers, be specifically related to a kind of large-sized end enclosure processing method.
Background technology
At present, end socket, as a kind of press member, is widely used in medical treatment, transport, the industry-by-industries such as weaving.End socket is the indispensable part of tankage, according to the difference of container application target and operating pressure, can adopt ellipsoidal head, butterfly end socket, hemispherical head, sphere end socket, band flanging or conical head (without straight flange), flat bottom cover etc.The method of processing end socket has pressing and spinning process etc.Pressing is the method utilizing mould forming head on forcing press, and the method often needs school shape, and stock utilization is low, and labour intensity large scale precision is low.Spinning process plate is rotated and utilizes spinning roller feed motion to realize turning round a kind of method that Plastic Forming processes required end socket, and existing spinning process processing dimension is limited, and equipment manufacturing cost is high.
