Follow-up hot spinning device and method for end socket piece

Abstract

The invention discloses a follow-up hot spinning device and method for an end socket piece. The follow-up hot spinning device comprises a spinning support and a pressing plate, and further comprises afollow-up supporting piece, a heating assembly, a supporting spring, a fixing seat and a connecting rod mechanism, wherein the follow-up supporting piece is arranged in an inner cavity of the spinning support in an up-and-down moving manner, the heating assembly is fixedly connected to the lower end of the follow-up supporting piece, the fixing seat is fixedly installed at the bottom of an innercavity of the spinning support, the upper end of the supporting spring is connected with the follow-up supporting piece, the lower end of the supporting spring is connected with the fixing seat, one end of the connecting rod mechanism is hinged to the fixing seat, and the other end of the connecting rod mechanism is hinged to the follow-up supporting piece. By means of the follow-up hot spinning device, the heating temperature at the deformation position of a workpiece is controllable and uniform, the sinking phenomenon of the bottom of the workpiece can be effectively relieved, and the hot spinning device is simple in structure, low in cost and high in engineering applicability.

Description

technical field [0001] The present invention relates to the technical field of plastic forming, in particular to a head member servo heating spinning device and spinning method. Background technique [0002] With the rapid development of aerospace technology and pressure vessels, the requirements for the shape of the head are becoming more and more complex, the size is getting larger, the performance requirements are getting higher and higher, and the material selection is becoming more and more diverse. In the spinning process of the head, more and more heads need to be hot-spun to complete the spinning, and the quality of the spinning is often related to the uniformity and accuracy of the heating temperature during the spinning process. Relationship. [0003] The existing spinning heating methods mainly include laser heating, induction heating and flame heating. Patent document CN201610917906.9 introduces a laser heating spinning method, which is to use a six-axis robot ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: a six-axis robot is required, which is extremely costly; at the same time, the robot needs to move synchronously with the rotary wheel, which is very difficult to implement because of space problems; and it uses a local heating method

The disadvantage of this method is that it is impossible to use a flat plate as a blank for spinning, and it is not suitable for head spinning

However, the disadvantages of these processes are: the flame temperature changes greatly, resulting in a large heating temperature difference, uneven heating temperature of the workpiece, and prone to overaging.
