Problems solved by technology

When the above-mentioned method is used to produce special-shaped rings with thin wall thickness, the rolling process cannot be completed smoothly due to unreasonable design of the blank or improper control of rolling parameters (such as the feed speed of the core roll, etc.), and intermittent failures will occur. Rolling phenomenon seriously affects the quality of the ring

[0036] The main chemical element content (percentage by weight) of the alloy is: 1.9% to 2.5% of Cu, 1.4% to 1.8% of Mg, 0.9% to 1.5% of Fe, 0.9% to 1.5% of Ni, 0.9% to 1.5% of Ni, The content of Ti is 0.02%-0.10%, the content of Mn is 0.20%, the content of Zn is 0.30%, the content of Si is 0.35%, other elements are individually ≤0.05% and the sum is ≤0.10%, and the balance is Al.

[0037] The steps of this method are as follows:

[0038] 1. Design rectangular ring blank 1

[0039] Calculate the rectangular blank dimensions as follows:

[0040] (1) The height of the rectangular ring blank 1 is:

[0041] h 1 =H 2 ;

[0042] Among them: H 1 is the height of the rectangular ring blank 1;

[0043] h 2 is the height of the special-shaped thin-walled ring 3.

Abstract

The invention discloses a method for rolling an aluminum alloy rectangular ring blank to form a specially-shaped thin-wall ring. In order to enable a rolling process to be continuously and stably processed, the invention discloses a reasonable feeding manner of a core roller and performing back-stepping design of an aluminum alloy rectangular ring blank according to shape and size of an aluminum alloy specially-shaped thin-wall ring so as to roll the aluminum alloy rectangular ring blank to form the specially-shaped thin-wall ring. The rolling method is mainly applied to forming of aluminum alloy specially-shaped thin-wall rings in fields of aviation, aerospace and industrial machinery.

Description

technical field [0001] The invention relates to a method for rolling and forming a ring, in particular to a method for rolling and forming an aluminum alloy rectangular ring blank into a special-shaped thin-walled ring. Background technique [0002] As the ring rolling technology becomes more and more mature, the design of the ring parts becomes more and more refined, and special-shaped thin-walled ring parts are produced accordingly. The shape and size of this special-shaped thin-walled ring are closer to the shape and size of the part, which can greatly reduce the machining allowance, thereby reducing the damage to the forging streamline of the ring by machining, saving a lot of precious metal materials, and improving the material quality. utilization rate. [0003] The Chinese invention patent specification CN101279344A published on October 8, 2008 discloses a rolling forming method of an aluminum alloy special-shaped ring. Ring billet, and then put the billet into the ...
