Induction heating upsetting device for aluminum alloy cylinder

Abstract

The invention provides an induction heating upsetting device for an aluminum alloy cylinder. The induction heating upsetting device comprises a headstock, an upsetting mechanism, an upsetting supportring, an induction coil, a forming die and a tailstock; the front end of the upsetting support ring is arranged on the headstock, the upsetting mechanism is arranged on the upsetting support ring in asleeving mode, the induction coil is arranged at the rear end of the upsetting support ring and is fixed at the front end of the forming die, and the rear end of the forming die is fixed on the tailstock; the central axes of the upsetting support ring, the induction coil and the forming die are positioned on the same straight line; the upsetting support ring can move relative to the induction coil along the axial direction; and the shapes of the upsetting support ring, the induction coil and the forming die are matched with each other. The induction heating upsetting device for the aluminum alloy cylinder in the invention greatly facilitates automation, the operation is simple, the size and the shape of a finished upsetting product are easy to control, the upsetting requirements of all aluminum alloy cylinders can be basically met, and great application prospect and market value are achieved.

Description

technical field [0001] The invention relates to an induction heating pier thickening device for an aluminum alloy cylinder. Background technique [0002] In the process of using the friction stir technology and equipment to weld the circular seam of the cylinder, controlling the main process parameter of the weld formation - the amount of pressure, will cause the phenomenon of thinning the wall thickness of the aluminum alloy cylinder, and the thinning amount is generally 0.2mm Between ~0.5mm, it will directly affect the forming quality and aesthetics of the weld. Especially in the UHV / UHV power industry, improper control of the downforce of stir welding will cause breakdown at the thinned part and cause safety accidents. [0003] Aiming at the thinning problem of stir welding, the commonly used treatment method in China at present is: before stirring welding, adopt the traditional TIG / MIG wire filling welding method, and surfacing a layer of thickness of 0.5mm to 1mm on th...

AI Technical Summary

Problems solved by technology

This method not only has problems such as large heat input, which causes welding deformation at the interface of the aluminum alloy cylinder (different degrees of warping phenomenon), but also requires cylinder rotating equipment during the surfacing welding process of the aluminum alloy cylinder, and the process is cumbersome. , The operation is difficult, which directly affects the forming quality of the subsequent stir welding cylinder
