Problems solved by technology

At present, the processing steps of this kind of parts are divided into rough machining, semi-finishing machining and finishing machining. Layer cutting is used for rough machining and finishing machining, and the machining efficiency is low. Due to the large removal allowance and excessive deformation during machining, it is difficult to guarantee Web Thickness Dimensional Accuracy

Embodiment

[0020] The tooling and fixtures used for rough machining, semi-finishing and finishing the first side of the parts include such as figure 1 The shown fixtures for rough machining and semi-finishing of ribbed surfaces; and figure 2 Fixtures for rough machining, semi-finishing and finishing parts without ribs shown in the edge; figure 1 and 2 It can be seen that the tooling fixture includes a support plate 1 on which a parallel iron 3 and a support 2 matching the parts are arranged. The shim 3 plays the role of auxiliary support for the part. There are four shims 3 with threaded holes in the shim 3, which are located on both sides of the width direction of the part. They are connected by screws to fix the part and the fixture to prevent collision due to the tool. Or the cutting force is too large to cause the movement of the parts. The tooling fixture is simple, the manufacturing period is short, and the use is convenient.

Abstract

The invention discloses a processing method for a thin web titanium alloy flange which is easy to operate and can eliminate deformation of parts. The processing method of the thin web titanium alloy flange includes the steps in turn: rough machining, semi-finishing, and finishing; in the process of rough machining, firstly, a hard alloy end mill is used, with a large depth of cut, low speed, Rough machining parts at low feed speed; then use machine clamp indexable milling cutter as the processing tool, and use shallow depth of cut and fast feed for contour cutting. The processing method of the thin web titanium alloy flange can quickly remove the blank allowance and improve the processing efficiency; and the allowance of each part is uniform, which is conducive to the programming of the semi-finishing part, and the machining and cutting are more stable.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method of a thin web titanium alloy flange. Background technique [0002] It is known that the web of the special-shaped curved surface shows a nonlinear change, and belongs to a typical large-scale thin web special-shaped part. At present, the processing steps of this kind of parts are divided into rough machining, semi-finishing machining and finishing machining. Layer cutting is used for rough machining and finishing machining, and the machining efficiency is low. Due to the large removal allowance and excessive deformation during machining, it is difficult to guarantee Web thickness dimensional accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-operate fixture, improve the metal removal rate, and reduce the deformation of the parts. The processing method of the thin-web titanium alloy flange. ...
