Whole forging near net forming process for inner ball cage sliding sleeve

Abstract

The invention provides a whole forging near net forming process for an inner ball cage sliding sleeve, comprising the following steps of: blanking, machining to prepare a blank, shot blasting, surface coating, rod part forward extruding, barrel part upsetting, barrel part reverse extruding, spheroidizing and annealing, phosphorus saponifying and barrel part finishing and forming. The inner ball cage sliding sleeve manufactured by adopting the process provided by the invention has the advantages of uniform structure, high density, strength and hardness, small size error, no follow-up machining, high processing efficiency, short production period, material conservation and high practical value.

Description

technical field [0001] The invention belongs to the field of near-net forming of metal materials, and in particular relates to an integral forging near-net forming process of an inner spherical cage sliding sleeve. Background technique [0002] The constant velocity universal joint is a mechanism that connects two shafts whose axes do not coincide and makes the two shafts transmit motion at the same angular velocity. It is an important part in the car transmission system. Its function is to transfer the power of the engine from the transmission transmission) to the driving wheel of the car, to meet the requirements of the outer end corner of the car transmission shaft, and to transmit the power of the engine to the wheels stably and reliably, to compensate for the beating of the suspension at the inner end of the car, and to drive the car at high speed; The joint is mainly composed of an inner ball cage, an outer ball cage, and a half shaft. As a key part of the inner ball ...

[0002] The constant velocity universal joint is a mechanism that connects two shafts whose axes do not coincide and makes the two shafts transmit motion at the same angular velocity. It is an important part in the car transmission system. Its function is to transfer the power of the engine from the transmission transmission) to the driving wheel of the car, to meet the requirements of the outer end corner of the car transmission shaft, and to transmit the power of the engine to the wheels stably and reliably, to compensate for the beating of the suspension at the inner end of the car, and to drive the car at high speed; The joint is mainly composed of an inner ball cage, an outer ball cage, and a half shaft. As a key part of the inner ball cage, the inner ball cage sliding sleeve plays the role of a joint socket in the transmission and directly determines the swing angle of the universal joint. A car needs at least two inner ball cage sliding sleeves, which are installed on both sides of the transmission wheel. The traditional processing method is machining technology, which has low processing efficiency, long production cycle and serious waste of materials. Therefore, it is necessary to improve
