Superplastic diffusion bonding hot-forming press for titanium alloy sheet part

Abstract

The invention relates to a superplastic diffusion bonding hot-forming press for a titanium alloy sheet part, which comprises a three-beam four-post type machine body, a working oil cylinder, a slide block and a movable worktable, wherein the three-beam four-post type machine body comprises an upper cross beam, a lower cross beam and a upright post. The superplastic diffusion bonding hot-forming press is characterized in that platforms made of ceramics and steel materials are respectively fixed on the lower plane of the slide block and the upper plane of the movable worktable; a synchronous adjusting mechanism for ensuring the pressing precision of the press in the forging process is installed among four corners of the upper cross beam and the lower cross beam through a support frame; and a heat insulation device is installed on the periphery of a working area of the press. The superplastic diffusion bonding hot-forming press has the advantages that the temperature of the forging press can be guaranteed not to be greatly lost, the pressing temperature during workpiece pressing is in a high-temperature state of 1000 DEG C continuously, and a mould is not required to be repeatedly heated in the forging process, so that the quality of pressed workpieces is ensured; the energy sources can also be greatly saved, the processing cost is reduced, and the production efficiency is improved; and the self parallelism degree of the slide block in the downward movement can be automatically adjusted by the synchronous adjusting mechanism to ensure the pressing precision of the titanium alloy sheet part in the forging process.

Description

technical field [0001] The invention belongs to the technical field of forging machinery, in particular to a thermoforming press for superplastic diffusion connection of titanium alloy thin plate parts. Background technique [0002] At present, with the rapid development of my country's aviation industry and the research and development of a new generation of fighter jets, helicopters, large aircraft, and high-performance engines, the manufacturing of aircraft has proposed high thrust-to-weight ratio, high reliability, high durability, long life, and low cost. And other requirements, so the requirements for materials and processes are also constantly improving, and a large number of difficult-to-deform alloys, such as titanium alloys and high-temperature alloys, are used. The forming process of large titanium alloy and superalloy forging mainly includes conventional die forging, isothermal precision forging / superplastic forming process, because the domestic aviation forging s...

AI Technical Summary

Problems solved by technology

The working area of ​​traditional forging equipment is an open structure. Due to the serious heat loss in the forging process of this structure, it is difficult for the forging temperature to reach an isothermal state; and the mold needs to be continuously heated to forge the next workpiece.

This not only wastes a lot of energy, affects work efficiency, and increases manufacturing costs; it also makes forging more difficult and the yield is very low

In addition, because the press for pressing titanium alloy thin plate parts requires a very high horizontal precision of the slide block in the pressing process, and the traditional forging equipment is limited by its structure and cannot meet its requirements, so the traditional forging processing machinery has been unable to adapt to the aviation industry. The status quo of rapid development
