Problems solved by technology
However, in the current production of spherical shell forgings, after forging, there are burrs around the edges of the spherical shell, and in the forging process, due to the use of traditional techniques, the utilization rate of materials is low, generally 70%-75%. As a result, the loss of materials accounts for 25%-30% of the product weight. At the same time, the investment in production equipment is large and the processing cycle is long.

Abstract
The invention discloses a machining method for an automobile spherical shell forging. The machining method comprises the following steps: a, material cutting, namely, cutting a rod material with the outside diameter of 32 mm into material sections with the length of 185 to 187 mm; b, heating, namely heating the material sections by adopting a medium frequency induction heating furnace, wherein the temperature of the material sections obtained after heating is between 1,100 and 850 DEG C; c, blank making, namely mounting a blank making mould by adopting an open-type tilting bench press, and performing stroke impact; d, finish forging, namely mounting a molding mould by adopting the open-type tilting bench press, placing a blank material into a lower molding mould, performing stroke impact, and taking out a qualified material part after the impact, wherein the qualified material part is the automobile spherical shell forging. According to the machining method for the automobile spherical shell forging, the periphery of a machined and molded product is smooth without a rough edge by machining the automobile spherical shell forging by adopting a new process; the material utilization rate is high, and reaches 95 to 97 percent; the material loss is reduced; the weight of the molded product is reduced; the molded product is firmer; the machining period of the product is short; the machining equipment investment is low; the machining method for the automobile spherical shell forging is very favorable for the development of an enterprise.
Description
technical field [0001] The invention belongs to the technical field of auto parts processing, and in particular relates to a processing method for an auto spherical shell forging. Background technique [0002] The steering system of the car is a very important system of the car, among which the spherical housing of the car steering gear is an important component, which realizes the functions of carrying and steering the car. However, in the current production of spherical shell forgings, after forging, there are burrs around the edges of the spherical shell, and in the forging process, due to the use of traditional techniques, the utilization rate of materials is low, generally 70%-75%. As a result, the loss of materials accounts for 25%-30% of the product weight, and at the same time, the investment in production equipment is large, and the processing cycle is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
