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: C content 0.50% ~ 0.60%, Mn content 0.50% ~ 0.80%, Si content ≤ 0.40%, S content ≤ 0.030%, P content ≤ 0.030 %, Cr content 0.50% ~ 0.80%, Ni content 1.40% ~ 1.80%, the balance is Fe.

[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 a rectangular die block steel ring blank into an abnormal-shaped thin-wall ring member. With the purpose of continuous and stable operation in a rolling process, a reasonable feeding type of a core roller is provided, the rectangular die block steel ring blank is designed according to the shape and the size of the abnormal-shaped thin-wall ring member in a backward reasoning mode, and therefore the rectangular die block steel ring blank is rolled into the abnormal-shaped thin-wall ring member. The method is mainly used for forming of the abnormal-shaped thin-wall ring member 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 mold steel 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 CN101279343A published on October 8, 2008 discloses a rolling forming method for stainless steel special-shaped rings. The billet is then put into the rolling die of the ...
