Alloy part forging process

Abstract

The invention belongs to the technical field of forging, in particular to an alloy part forging process. A forging device used in the process comprises a worktable, wherein two push rod motors are symmetrically mounted in the middle of the edge of the worktable, a rectangular plate is in clamped connection to the top ends of the push rod motors, an upper die is fixed to the bottom end of the rectangular plate and is used for forging the inner side wall of a blank, a lower die is fixed in a middle position of the top end of the worktable and is used for forging the outer side wall of the blank,and a controller is arranged on the worktable and is used for controlling the forging device to work. By forging a circular tubular product for many times, the circular tubular product becomes a polygonal tube, so that sections of the aluminum alloy tubes are various, and therefore, the forging efficiency of the polygonal aluminum alloy tube is improved favorably and thus, the application range of the aluminum alloy tube is further improved.

Description

technical field [0001] The invention belongs to the technical field of forging, in particular to a forging process of an aluminum alloy part. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. [0003] There are also some technical solutions for forging aluminum alloy tubes in the prior art, such as a Chinese patent with application number CN201922104389.5, which discloses a ring rolling process for aluminum alloy thin-walled conical rings. The forging device can simultaneously roll the two ends of the thin-walled conical ring, a...

Problems solved by technology

[0003] There are also some technical solutions for forging aluminum alloy tubes in the prior art, such as a Chinese patent with application number CN201922104389.5, which discloses a ring rolling process for aluminum alloy thin-walled conical rings. The forging device can simultaneously roll the two ends of the thin-walled conical ring, and can also roll the inner and outer peripheral walls of the thin-walled conical ring, so that the radial wall thickness of the thin-walled conical ring is reduced, and the axial Continuous local plastic deformation toward height reduction, inner and outer diameter expansion, and cross-sectional profile forming, so that the radial and axial dimensional accuracy of the finished forging can be guaranteed at the same time; the upper and lower rolls play a role in trimming during the rolling process The role of the two ends of the finished forging, but can only be forged for circular rings, can not be forged for polygonal rings, so that the scope of application of the invention is limited
