Problems solved by technology

[0002] Due to the poor fluidity of the material during thermal processing of the 6061 aluminum alloy, it is difficult to divide the metal material during special-shaped rolling. The size of the billet increases, which leads to insufficient deformation in subsequent special-shaped rolling, resulting in partial filling dissatisfaction, stepping angle phenomenon, and easily causing size mismatch, and some sizes do not meet the requirements.

Embodiment 1

[0031] A method for manufacturing a C-shaped aluminum alloy ring forging, comprising the following steps: (1) upsetting and punching after blanking 6061 aluminum alloy; (3) The upper and lower ends of the ring blank are bulged and tilted by the single-sided bulging method; (5) The flat end face of the blank is shaped by a hydraulic press; (6) The shaped blank is rolled by a mold;

[0032] The tilting is to firstly bulge one end of the ring blank into a trumpet shape, then turn over the ring blank, and bulge and break the other end, so that the upper and lower ends of the ring blank are in a symmetrical trumpet shape.

[0033] The single-sided bulging method specifically uses the downward movement of the pyramid of the bulging machine to move the lateral sides of the bulging mold outward, so that the parts in contact with the mold can be tilted and divided into materials.

[0034] In the step (6), the rolling deformation is 50%, and 3% is reserved for bulging.

[0035] The ste...

Abstract

The invention relates to the technical field of special-shaped forge piece manufacturing processes, in particular to a C-shaped aluminum alloy ring forge piece manufacturing method. A C-shaped 6061 aluminum alloy ring forge piece is manufactured through the steps of upsetting, punching, single-face bulging, inclined breaking, special-shaped rolling and the like. The C-shaped 6061 aluminum alloy ring forge piece manufactured through the method can effectively increase the material utilization rate, the cost is reduced, and the forging defects such as insufficient filling and treading angle of the forge piece are eliminated.

Description

technical field [0001] The invention relates to the technical field of manufacturing process of special-shaped forgings, in particular to a manufacturing method of C-shaped aluminum alloy ring forgings. Background technique [0002] Due to the poor fluidity of the material during thermal processing of the 6061 aluminum alloy, it is difficult to divide the metal material during special-shaped rolling. The increase in the size of the billet will lead to insufficient deformation in the subsequent special-shaped rolling, resulting in partial filling dissatisfaction, stepping angle phenomenon, and easily causing size mismatch, and some sizes do not meet the requirements. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for manufacturing a C-shaped aluminum alloy ring forging, comprising the following steps: [0004] (1) Upsetting and punching after cutting the raw materials; [0005] (2) Carry out horse...
