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

Abstract

The invention discloses a method for rolling a nickel-base super-alloy rectangular ring blank to form a special-shaped thin-wall ring piece. In order to continuously and stably carry out the rolling process, the invention provides a reasonable core roller feeding mode. The nickel-base super-alloy rectangular ring blank is designed in an inversion manner according to the shape and size of a nickel-base super-alloy special-shaped thin-wall ring piece, so that the nickel-base super-alloy rectangular ring blank can be rolled to form the special-shaped thin-wall ring piece. The method is mainly used for forming the nickel-base super-alloy special-shaped thin-wall ring piece in the fields of aviation, aerospace, industrial machinery and the like.

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 a nickel-base superalloy 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 CN101279346A published on October 8, 2008 discloses a rolling forming method of nickel-based superalloy special-shaped rings. , Twice rolling the ring billet,...
