Problems solved by technology

[0002] In the prior art, the machining process of ring-shaped metal parts with hollow and thin walls is a recognized problem in the world. When processing such workpieces, the workpiece is easily deformed. The deformation factors include product clamping deformation, material deformation or machining deformation. , these factors are the difficulties faced by process engineers, that is, the cost and efficiency of processing must also be considered, and the processing accuracy caused by deformation caused by production must also be considered. Therefore, it is necessary to comprehensively analyze the processing process of the entire part, which is obviously already become a complex technical problem

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0026] Examples of the present invention figure 1 The hollow and annular thin-walled workpieces shown have a wall thickness of 1.97mm; materials around 4140 and 30HRC are suitable for the production of this type of thin-walled parts, providing guidance for material selection.

[0027] Its processing procedure is as follows:

[0028] Process 1, warehousing inspection: after passing the heat treatment inspection of the workpiece blank, it is put into the warehousing for processing;

[0029] Process 2, on the lathe, semi-finishing the workpiece blank, first clamping the outer circle of the workpiece blank, semi-finishing the inner hole and end face...

Abstract

The invention discloses a machining process for an annular thin-wall part and a tool thereof. According to the machining process for the annular thin-wall part and the tool thereof, multiple times of half finish turning and finish turning are adopted, stress ageing is combined, and the influence of material stress and machined surface stress on the product dimensional precision is gradually reduced; innovative thinking is applied to the design of a tool clamp, rough turning and finish turning are conducted on an inner hole in a mode that an outer circle is positioned and an end surface is clamped, thus, the product clamping and positioning precision is high, and stress strain is gradually released; and the outer circle is subjected to rough turning and finish turning and a hollow-out groove is subjected to finish milling in the mode that inner holes of the two ends of expansion rings are clamped and positioned, so that the product positioning precision is high, and clamping is firm. By means of the machining process for the annular thin-wall part and the tool thereof, the labor intensity of workers is relieved, the production cost is reduced, the labor productivity is improved, using is safe, and the product quality is improved.
