Problems solved by technology
For ordinary titanium alloy forgings, the production process is relatively mature, while aerospace special-shaped forgings (such as wheels, etc.) have strict performance indicators, the forging process is more complicated, and usually require large-scale die forging equipment to be formed by die forging, but the cost of die forging tooling is relatively high. Large, about hundreds of thousands to hundreds of thousands, high technical requirements, not conducive to early research and development work

Embodiment 1
[0017] Such as Figure 1-3 As shown, the method for producing titanium alloy special-shaped forgings using free forging equipment in this embodiment includes the following steps:
[0018] (1) Calculation of feeding weight: according to the volume of the forging billet before machining, that is figure 1 The volume contained by the red dotted line in the middle, the forging before the computer is added, that is, the weight M of the blank, that is, the weight M of the feeding;
[0019] (2) Tooling design: According to the size of the forging before machining, that is, the size of the blank, the forging mold is designed. The forging mold includes an upper mold and a lower mold. The upper mold is a convex mold, and the cavity of the lower mold is two different sizes. The round table is stacked up and down, and the bottom diameter φD of the lower mold cavity is consistent with the bottom outer diameter φD of the forging before machining. For the convenience of demoulding, the demou...

The invention discloses a method for producing titanium alloy special-shaped forgings by using free forging equipment. The method comprises the steps of feeding weight calculation, tooling design, blank preparation, pre-forming and forming. The method for producing the titanium alloy special-shaped forgings by using the free forging equipment utilizes existing free forging equipment to produce thespecial-shaped forgings, and a simple forging die and a demoulding device only need to make, so that the development cost is low, the cycle is short, the one-time investment is small, and the technical requirements are not high. The method for producing the titanium alloy special-shaped forgings by using the free forging equipment is suitable for production of die forgings in the development stage and production of small batch die forgings.
Description
technical field [0001] The invention relates to a method for producing titanium alloy special-shaped forgings by using free forging equipment, and belongs to the technical field of titanium alloy forging. Background technique [0002] Titanium alloys are widely used in the fields of aerospace, aviation and ships because of their advantages such as high strength, high temperature resistance and corrosion resistance. For ordinary titanium alloy forgings, the production process is relatively mature, while aerospace special-shaped forgings (such as wheels, etc.) have strict performance indicators, the forging process is more complicated, and usually require large-scale die forging equipment to be formed by die forging, but the cost of die forging tooling is relatively high. Large, about hundreds of thousands to hundreds of thousands, the technical requirements are high, which is not conducive to the early research and development work. Although the relatively simple special-sha...
