Anti-wrinkle machining method for aluminum alloy bent pipe fitting

Abstract

The invention relates to an anti-wrinkle machining method for an aluminum alloy bent pipe fitting. The method comprises the following steps: S1, mounting and positioning, specifically, horizontally clamping a aluminum alloy pipe fitting; S2, lining pipe penetrating, specifically, enabling a lining pipe with the outer diameter equal to the inner diameter of the aluminum alloy pipe fitting to be bent to penetrate into the aluminum alloy pipe fitting, wherein the end of the lining pipe needs to penetrate through the bending position; S3, follow-up bending, specifically, releasing positioning in the length direction of the aluminum alloy pipe fitting, and then carrying out follow-up bending till a complete bending angle is achieved; and S4, pipe fitting cutting, specifically, cutting off the bent part of the pipe fitting through a cutting device. According to the anti-wrinkle machining method for the aluminum alloy bent pipe fitting, through the follow-up bending step, the rigid force borne by the bent part of the pipe fitting in the length direction of the pipe fitting can be reduced in the bending process of the pipe fitting, meanwhile, irregular deformation of the inner wall and the outer wall of the pipe fitting generated when the pipe fitting is bent is reduced through the lining pipe, therefore, the wrinkle probability of an obtained bent product is reduced, and the quality of the product is improved.

Description

technical field [0001] The present application relates to the technical field of aluminum alloy parts processing, in particular to an anti-wrinkle processing method for aluminum alloy bent pipe parts. Background technique [0002] Aluminum alloy extruded profiles are very common alloy products used in life, and are widely used in all aspects of life. Aluminum alloy pipe fittings are a kind of aluminum alloy extruded profiles. The general processing method is to obtain the aluminum alloy pipe fittings with the required inner and outer diameters through perforation extrusion and combined die extrusion, and then coat and fold the aluminum alloy pipe fittings. Bending, cutting and other processing to obtain products. [0003] In view of the related technologies mentioned above, the inventor believes that there are often wrinkles at the bend of the aluminum alloy pipe fittings during bending, which affects the quality of the product.
