A follow-up heating spinning device and spinning method for head parts

Abstract

The invention discloses a follow-up heating spinning device and a spinning method for a head piece. The follow-up heating spinning device includes a spinning support and a pressing plate, and also includes a follow-up support, a heating assembly, a support spring, and a fixing seat. and the connecting rod mechanism, the follower support is set in the inner cavity of the spinning support so that it can move up and down, the heating assembly is fixedly connected to the lower end of the follower support, and the fixed seat is fixedly installed at the bottom of the inner cavity of the spinning support. The upper end of the support spring is connected with the follower support, the lower end of the support spring is connected with the fixed seat, one end of the link mechanism is hinged with the fix seat, and the other end of the link mechanism is hinged with the follower support. The heating temperature at the deformed part of the workpiece of the servo heating spinning device is controllable and uniform, can effectively alleviate the sinking phenomenon at the bottom of the workpiece, and has simple structure, low cost and strong 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.
