Clamping tooling assembly and machining process method for titanium alloy foil parts

Abstract

The invention discloses a clamping tooling assembly and a machining process method for titanium alloy foil parts, and belongs to the technical field of machining forming of titanium alloy foils. According to the method, the surface of the titanium alloy foil part is cleaned up, a sucker is aligned, a vacuum drying pump is started, the titanium alloy foil part is rapidly inserted into the sucker, the position of the titanium alloy foil part in the sucker is calibrated, the vacuum pump is started to exhaust air of the interior of the sucker, so that the suction force of the sucker reaches 0.7MPa, a quick coupling is taken down, the sucker is taken down, the sucker is clamped on a lathe, and whether the titanium alloy foil part is loosened or not is checked by using a dial indicator; and a ceramic tool is used for carrying out turning on the appearance of the titanium alloy foil part, and the titanium alloy foil part is turned for two times. According to the method, the pneumatic adsorption positioning and fastening mode is adopted, so that the surface of the foil part is uniformly stressed, accurate positioning is achieved, the ceramic tool is further adopted, so that the surface quality of the small-allowance fine machining process is guaranteed. The method is suitable for machining process for the titanium alloy foil parts.

Description

technical field [0001] The invention relates to a machining process method for clamping tooling components and titanium alloy foil parts, and belongs to the technical field of machining and forming of titanium alloy foils. Background technique [0002] Lightweight has a great impact on the loading, transportation, range, and flight speed of the aircraft. High-speed aircraft have strict requirements on materials. Traditional magnesium-aluminum alloy parts are easily oxidized at high temperatures caused by high-speed friction. Titanium alloys and high-temperature alloys are usually used. At present, titanium alloy bellows are widely used in the field of high-speed aircraft as an inlet connection component. It is formed by foil diffusion connection and has good rigidity after stress relaxation and shaping. [0003] During the machining process of titanium alloy, due to the low plasticity and elastic modulus of titanium alloy, the stress on the tool surface is large during the ...

Problems solved by technology

[0004] In order to solve the problems that the traditional clamping and positioning method is not suitable for titanium alloy foil parts, which will cause multiple depressions on the surface of the foil parts, excessive flatness, excessive warpage, and high scrap rate, the present invention provides a A machining process method for clamping tooling components and titanium alloy foil parts. This method can obtain products with high dimensional accuracy (±0.01mm) and surface quality that meet the requirements for diffusion welding processing. The foil products after this processing method are used for processing The overall strength and airtightness (no leakage under 6.0Mpa) of the diffusion-connected product meet the technical requirements
