Example Embodiment

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to the above.

[0024] The present invention provides a method for processing T4 aluminum alloy thin-walled disc-shaped parts, such as Figure 1 to Figure 4 As shown, including the following steps:

[0025] Step 1: Provide a cylindrical blank, use a lathe to cut the blank, remove most of the material on the surface of the blank, and reserve appropriate roughing allowances on the outer surface and both ends of the blank to obtain the workpiece; the preferred roughing allowance thickness is 1mm. Using a lathe to cut the blank is carried out by clamping the blank on the lathe spindle through a three-jaw chuck.

[0026] Step 2: Use a milling machine to mill the workpiece in step 1, remove part of the material in the rough machining allowance on the surface of the workpiece, and reserve an appropriate finishing allowance;

[0027] Step 3: Perform aging treatment o...

Abstract

The invention provides a machining method ofa T4 aluminum alloy thin-walled disk-shaped part, which comprises the steps that a cylindrical blank is provided, a lathe is used for cutting a blank and reserving rough machining allowance, a milling machine is used for milling a workpiece and reserving finishing allowance, the workpiece is subjected to aging treatment, the workpiece is calibrated, thelathe is used for finishing the excircle surface and the two end surfaces of the workpiece, and the milling machine is used for machining various shape features on both end surfaces of the workpiece.According to the machining method ofthe T4 aluminum alloy thin-walled disk-shaped part, the sequence of machining technology of the aluminum alloy thin-walled disk-shaped part is optimized, and the aging treatment removes residual cutting thermal stress remained in the workpiece during rough machining, so that in the subsequent finishing stage, deformation of the workpiece caused by the residual cutting thermal stress is reduced, a foundation for improving themachining quality and machining accuracy is laid,the calibration process calibrates the shape and size of the outer contour of the workpiece, the finished product machining pass rate of the part is ensured, and the machining accuracy and processing quality are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing technology, in particular to a processing method of a T4 aluminum alloy thin-walled disc-shaped part. Background technique [0002] Thin-walled disc-shaped parts are widely used in various industrial sectors in the national economy. However, when the material of thin-walled disc-shaped parts is aluminum alloy, due to the weak strength and poor rigidity of the aluminum alloy material, it is difficult to process such thin-walled disc-shaped parts. The workpiece is easily deformed when it is a disc-shaped part, which affects the machining accuracy and quality of the part. For a long time, the processing of aluminum alloy thin-walled disc-shaped parts has become an urgent technical problem in the process of mechanical cutting. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a processing method of T4 aluminum a...
