Embodiment Construction

[0032] To implement the processing method of the Ti1023 alloy special-shaped ring according to the present invention, equipment such as a forging heating furnace, a press, a ring rolling machine, and a manipulator must be provided.

[0033] The main chemical element content (percentage by weight) of the alloy is: 2.6% to 3.4% of Al, 9.0% to 11.0% of V, 1.6% to 2.2% of Fe, 0.05% of C, and 0.05% of N. %, H content is 0.015%, Y content is 0.005%, O content is 0.13%, and the balance is Ti.

[0034] The steps of this method are as follows:

[0035] Heating the Ti1023 alloy rod blanked according to the specification to the forging temperature below the phase transformation point of 30°C, and pre-rolling into a pre-rolled ring billet 31 after upsetting and punching;

[0036] After reheating the pre-rolled ring blank 31 to the forging temperature, put it into the ring rolling machine; start the ring rolling machine, such as figure 1 As shown, the main roll 11 rotates counterclockwis...

Abstract

The invention discloses a processing method of a Ti1023 alloy special-shaped ring. By setting the matching relationship between the feed speed of the core roll of the rolling ring, the pressing speed of the upper cone roll, and the rotational speeds of the upper cone roll and the lower cone roll, Realize the processing of Ti1023 alloy special-shaped rings, and obtain Ti1023 alloy special-shaped rings with good structure and performance and complete rolling lines. This rolling method is mainly used in the forming of Ti1023 alloy special-shaped rings in the fields of aviation, aerospace, industrial machinery and the like.

Description

technical field [0001] The invention relates to a rolling forming method of a ring, in particular to a processing method of a Ti1023 alloy special-shaped ring. Background technique [0002] As the ring rolling technology becomes more and more mature, the design of ring parts becomes more and more refined, and the design of special-shaped ring parts is more popular. The shape and size of this kind of ring are closer to the shape and size of the part, which can greatly reduce the machining allowance and reduce the damage to the forging flow line of the ring by machining. At the same time, it saves a lot of precious metal materials and improves Material utilization. [0003] In the prior art, the shape and size of the ring blank are reversely designed according to the shape and size of the ring and the special-shaped structure of the main roll and core roll of the ring rolling machine, and the special-shaped thin-walled ring is completed through a reasonable core roll feeding ...
