Embodiment Construction

[0027] The specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, taking a ring gear forging with a material of 42CrMoA and a specification of Φ1495mm×Φ1220mm×Φ1080mm×360mm×70mm (Df0×df0×df1×H×Hf) as an example.

[0028] Such as image 3 As shown, a rolling forming method of a T-shaped cross-section full-fiber ring gear specifically includes the following steps:

[0029] Step 1. Ring blank design: design the ring blank 2 according to the forging size, core roll size, deformation distribution ratio, deformation law and cross-section similarity principle, among which D m0 1035mm, d mo 600mm, d m1 370mm, H 0 360mm, H m 70mm.

[0030] Step 2. Blanking and heating: Blanking is carried out according to the weight of the forging, heated to 850°C and kept for 1-2 hours, then continue to heat up to the initial forging temperature of 1150°C, and kept for 2-3 hours;

[0031] Step 3. Billet making: Upsetting the ...

Abstract

The invention discloses a rolling forming method of a full-fiber ring gear with a T-shaped section, which includes the following steps: ring blank design: according to the size of the forging, the size of the core roll, the distribution ratio of deformation, the law of deformation and the principle of cross-section similarity, etc. Design; blanking and heating: blanking according to the weight of the forging, and heating to the initial forging temperature; billet making: upsetting the heated billet, punching round holes, and then pressing steps on both sides of the billet with a special-shaped punch , the outer circle is as round as possible until it meets the designed dimensions, and the blank is completed; the finished ring blank is reheated to the initial forging temperature, and after a period of heat preservation, it is rolled and formed on a horizontal ring rolling machine to obtain T Cross-section full-fiber ring gear. Improve the utilization rate of raw materials, reduce the processing allowance, shorten the product processing cycle, and the produced ring gear has good flow and simple process.

Description

technical field [0001] The invention belongs to the technical field of special-shaped cross-section ring processing, and relates to a rolling forming method of a T-shaped cross-section full-fiber ring gear. Background technique [0002] The T-section ring gear is a typical up-and-down symmetrical special-shaped section ring, which is widely used in petroleum, wind power equipment and other fields. Due to the complex rolling deformation rules of this kind of rings, the rolling forming is difficult, and the rolling forming quality is difficult to guarantee. The production of such rings is often rolled into rectangular cross-section rings, and then formed by subsequent machining. Large quantity, low material utilization rate, long processing cycle, and poor metal flow linearity of forgings. Therefore, the direct rolling forming technology of this kind of ring is the key technology that urgently needs to be solved. Contents of the invention [0003] The object of the present...
