Embodiment Construction

[0030] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments:

[0031] see attached figure 1 As shown, this kind of die for multi-directional forging of titanium alloy includes an upper die 1 and a lower die 3, and the titanium alloy blank 4 is forged between the upper die 1 and the lower die 3, and the lower surface of the upper die 1 and the lower die 3 are forged. The bulge-shaped protrusions 5 are evenly distributed on the upper surface of the upper mold, the bulge-shaped protrusions 5 are semicircles with the same diameter and are arranged in an arrangement, and the bulge-shaped protrusions 5 of the upper mold 1 and the lower mold 3 are mutually The upper and lower staggered distribution, the interval between the adjacent bulge-shaped protrusions 5 on the upper die 1 and the lower die 3 is 1 / 10 of the length of the side of the titanium alloy blank 4 along the horizontal travel ...

Abstract

The invention discloses a die for realizing multidirectional forging of titanium alloy and a processing method thereof. According to the technical scheme, the problems of large size allowance, low automation level and the like in the forging process of a titanium alloy blank can be effectively solved. In the multi-directional forging process of the titanium alloy blank, the titanium alloy blank is forged in a closed special-shaped die, three-directional stress and the multi-dimensional size are restrained, the material allowance is effectively controlled, and the material utilization rate is increased; in the multidirectional forging process of the titanium alloy blank, deformation and transposition are achieved through dislocation of the upper die and the lower die and the plug, the semi-automation degree is high, and the forging efficiency is improved; the bulge-shaped protrusions on the inner side of the die promote multidirectional deformation of the titanium alloy on one hand and serve as fulcrums for transposition of the titanium alloy blank on the other hand, and compared with a flat anvil, the bulge-shaped protrusions can enable the titanium alloy blank to obtain larger deformation and enable the microstructure to be finer and more uniform.

Description

technical field [0001] The invention relates to a tooling die capable of realizing multi-directional forging of titanium alloy and a method for using the same, belonging to the technical field of hot processing, and relates to the improvement of multi-directional forging process of titanium alloy. Background technique [0002] Titanium and titanium alloys are ideal metal structural materials. They have the advantages of high specific strength, good high temperature performance, corrosion resistance and good biocompatibility. They are widely used in aerospace, ships, and multi-directional forging technology. A representative process of plastic deformation, compared with other large plastic deformation methods, has the advantages of simple process and low cost, and can be completed by using existing industrial equipment. Multi-directional forging technology was first proposed by Salishchev G A and others and developed in the 1960s. Its essence is the free forging process of mu...
