Turning tooling and method for large thin-walled conical aluminum alloy parts

Abstract

The invention relates to a turning tool and turning method of a large thin-wall conical aluminum alloy part, and belongs to the field of machining of large thin-wall conical aluminum alloy forgings. According to a fixture for the large thin-wall conical aluminum alloy forgings, a supporting plate is used for fixing the outer walls of the thin-wall conical aluminum alloy forgings, the machining deformation in the machining process is controlled, the uniformity of the wall thickness of final products is guaranteed, the machining efficiency is improved, and the machining quality is guaranteed. Bychanging the type of the supporting plate and a cushion block, the problem that machining fixtures for thin-wall conical aluminum alloy forgings with different sizes are not universal is solved, andthe machining cost is reduced.

Description

technical field [0001] The invention relates to a tooling and method for turning large-scale thin-walled conical aluminum alloy parts, belonging to the field of processing large-scale thin-walled conical aluminum alloy forgings, and in particular to a turning method for large-scale thin-walled conical aluminum alloy parts. The inner diameter of the aluminum alloy part is 1500-4000mm, and the thin wall means that the thickness-to-diameter ratio is 0.01-0.001. Background technique [0002] The wall thickness of common large thin-walled aluminum alloy parts is only 0.5% to 0.3% of the diameter, and its own rigidity is poor. It is easy to vibrate under the action of cutting force during the overall turning process. At the same time, the release of cutting stress causes the parts to deform. Inconsistent depth of cut for each cut. Under the influence of this dual effect, the overall roundness of the part becomes poor, and the wall thickness is difficult to control, which is not c...

Problems solved by technology

[0002] The wall thickness of common large thin-walled aluminum alloy parts is only 0.5% to 0.3% of the diameter, and its own rigidity is poor. It is easy to vibrate under the action of cutting force during the overall turning process. At the same time, the release of cutting stress causes the parts to deform. Inconsistent depth of cut for each cut

Under the influence of this dual effect, the overall roundness of the part becomes poor, and the wall thickness is difficult to control, which is not conducive to the guarantee of the final size of the part

[0003] At present, in order to ensure that the parts do not deform when processing this type of parts, the vertical turning center often adopts low cutting speed, low cutting depth and small feed, which seriously affects the processing efficiency. During the processing, the deformation of the parts cannot be controlled, and the final product Wall thickness varies

There are no general clamping tools at home and abroad, and fixtures need to be specially designed according to the parts
