Problems solved by technology

[0004] The purpose of the present invention is to provide an isothermal extrusion process for titanium alloy profiles, which solves the problem of uneven deformation of the titanium alloy billet caused by the large temperature difference between the surface and the core of the titanium alloy billet in the prior art, and the material is more deformed under the action of stress. Easy to crack, uneven forming

Abstract

The invention relates to an isothermal extrusion process for a titanium alloy profiled bar, which belongs to the technical field of metal material forming, and comprises the steps of titanium alloy blank heating, mold heating, automatic discharging, isothermal extrusion and automatic material taking. By preheating a titanium alloy blank and a forming die respectively, then the constant temperature of the titanium alloy blank in the extrusion forming process is kept through an isothermal mechanism, and the problem that in the prior art, when the titanium alloy blank is subjected to extrusion forming, due to the fact that the temperature difference between the surface and the core is large, deformation is uneven is solved; after preheating the titanium alloy blank, extrusion treatment is carried out, the tolerance of the titanium alloy blank is improved; the defects that the titanium alloy blank is prone to cracking and uneven in forming under the action of a pressing rod are effectively overcome; and in addition, the hollow pipe titanium alloy blank is adopted, the titanium alloy blank is not prone to stacking in the machining process, and the utilization rate of the titanium alloy blank is increased.

Description

technical field [0001] The invention belongs to the technical field of metal material forming, and in particular relates to an isothermal extrusion process for titanium alloy profiled material. Background technique [0002] Titanium alloys are widely used in medical, aviation, military, automobile manufacturing and electronic product manufacturing industries due to their low density, high strength and corrosion resistance. Parts in electronic products have different shapes, so processing is more difficult, and the casting process of titanium alloy is not mature enough, and product performance cannot be guaranteed. Therefore, extrusion process is a better choice for the production of special-shaped parts. [0003] However, due to the low thermal conductivity of titanium alloy, the temperature difference between the surface temperature and the core temperature of the titanium alloy billet is large, which may easily cause uneven deformation of the titanium alloy billet. Under t...
