Rolling forming method of T-type cross section full fiber gear ring

Abstract

The invention discloses a rolling forming method of a T-type cross section full fiber gear ring. The method comprises procedures as follows: design of a ring blank: the ring blank is designed according to sizes of a forge piece and a core roll, the deformation distribution ratio, deformation rules, section similarity principle and the like; unloading and heating: unloading is performed according to the weight of the forge piece, and the forge piece is heated to the initial forging temperature; blank making: a well heated blank material is subjected to upsetting and round hole punching, two side surfaces of the blank material are sequentially subjected to step pressing by use of a special-shaped punch, an outer circle is as round as possible until designed sizes are met, and blank making iscompleted; the prepared ring blank is reheated to the initial forging temperature and kept at the temperature for a period of time, rolling forming is performed on a horizontal ring rolling machine,and the T-type cross section full fiber gear ring is obtained. The utilization rate of raw materials is increased, machining allowance is reduced, the machining cycle of a product is shortened, the produced gear ring has good linearity and the process is simple.

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...
