Problems solved by technology

[0003] The disadvantages of the hot forging process are: first, the consumption of raw materials in the manufacturing process is large; second, the power consumption is large, and the forging size is inaccurate; third, the surface of the formed universal joint fork is rough; fourth, it is not easy to machine. poor precision
[0004] The disadvantages of the casting process are: first, the power consumption is large; second, it is not environmentally friendly and pollutes the environment; third, the processed universal joint fork has low strength and is easy to break; fourth, the production cost is high

Embodiment Construction

[0019] A kind of processing technology of universal joint yoke, the procedure of the processing technology of described universal joint yoke is: be that the diameter is 28mm round steel bar material cutting blanking, cutting length is 42mm-then the round steel bar that is lowered The material is subjected to the first annealing treatment - the first saponification treatment - the first cold extrusion process - then the second annealing treatment - the second saponification treatment - the second cold extrusion process - Excess material on the ears is then cut away - and finally machined and formed into the finished product.

[0020] Basic working principle:

[0021] The universal joint fork is installed on the steering wheel turning rod of the vehicle, and connected with relevant components, so that the vehicle can be manipulated.

[0022] Since the products formed by the cold extrusion process are used, compared with the forging process, the universal joint fork adopting the...

Abstract

The invention discloses a universal joint fork processing process. The process comprises the following steps: cutting a round steel bar with diameter of 28 mm into sections with the length of 42mm, and blanking; performing the first annealing treatment; performing the first saponification treatment; performing the first cold extrusion processing; performing the second annealing treatment; performing the second saponification treatment; performing the second cold extrusion processing; cutting off arc-shaped redundant materials of two lugs; and machining and forming the finished product. By the universal joint fork processing process disclosed by the invention, the structural strength and surface glossiness of a vehicle universal joint fork can be improved, and the process has the characteristics of reasonable process steps, material saving, low carbon and environment friendliness and low manufacturing cost.

Description

technical field [0001] The invention relates to a processing technology of a universal joint yoke, which belongs to the technical field of manufacturing auto parts. Background technique [0002] At present, the universal joint fork, which is widely used in the steering system of the vehicle, is mainly manufactured by two kinds of machining processes: one is hot forging process, and the other is casting process. All there is bigger defective in these two kinds of crafts. [0003] The disadvantages of the hot forging process are: first, the consumption of raw materials in the manufacturing process is large; second, the power consumption is large, and the forging size is inaccurate; third, the surface of the formed universal joint fork is rough; fourth, it is not easy to machine. Poor accuracy. [0004] The disadvantages of the casting process are: first, the power consumption is large; second, it is not environmentally friendly and pollutes the environment; third, the proces...
