Forming device and method for end socket with baffle

Abstract

The invention discloses a forming device and method for an end socket with a baffle. The device comprises a C-shaped cantilever, a tool base, a rotary wheel, a rotary wheel frame, a baffle frame and a telescopic arm, wherein the tool base and the baffle frame are fixedly arranged at the two ends of the C-shaped cantilever respectively; the telescopic arm is movably arranged in the tool base; the rotary wheel frame is movably arranged at one end of the telescopic arm; the rotary wheel is movably arranged at the bottom of the rotary wheel frame. The forming device and method have the advantages that the problem that due to shear spinning and pulling thinning action of a multi-pass forming rotary wheel in the traditional process, the wall thickness is decreased too much is avoided, the wrinkling defect is overcome effectively, and evenness of the wall thickness is improved remarkably; the bearing stiffness of a flange is further improved in the forming process, and the stress condition of a plate in the forming process is effectively improved; the problems that multiple passes exist and shear spinning and conventional spinning are mixed in the traditional forming process of the end socket are solved; the novel process mechanism is easy to implement.

Description

technical field [0001] The invention relates to a forming process in the technical field of plastic forming, in particular to a one-pass general rotation forming process for a thin-walled aluminum alloy head with a baffle. Background technique [0002] The head is an important part widely used in boilers, pressure vessels, chemical containers, rocket shells, nuclear reactors and artificial satellites, etc., and its specifications are developing in the direction of large-scale and thin-walled. The traditional petal splicing method is inefficient and the overall mechanical properties of the head are not uniform. The spinning method can obtain integrally seamless rotary parts. Spinning belongs to the problem of single-point continuous deformation. During the forming process, the tail top presses the sheet material on the mandrel, and under the action of friction, it rotates at high speed with the spindle of the machine tool. The spinning wheel moves longitudinally and laterally...

AI Technical Summary

Problems solved by technology

The disadvantage is that the size of the component is large, and it is difficult to guarantee the shape accuracy of the workpiece without a mandrel; the contact between the forming rod and the flange is a point contact, the support rigidity is small, and the wrinkling is serious during the forming process, which requires multiple passes. Forming will bring about the problem of excessive wall thickness reduction; the spinning roller and the forming roller need different control systems to control them separately, the mechanism is complex, and the multi-pass trajectory planning is cumbersome
