Embodiment Construction

[0021] The specific content of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The processing technology of the special-shaped blind hole flange type inner ball cage precision forging includes the following steps: raw material - blanking - heating - upsetting - back extrusion - spheroidizing annealing - machining - phosphorus saponification treatment - pre-processing Forming - fine forming.

[0023] like figure 2 , image 3 As shown, in this embodiment, in the raw material step (1): carbon-bonded steel, bonded steel, and gear steel with a carbon content of less than 0.55% are used;

[0024] (2) in the described blanking step: take 50~ For sawing of 100mm round steel bar, the blanking weight is greater than the calculated weight of the blank forgings of the blind hole flange type inner ball cage, but not more than 10%;

[0025] (3) in the described heating step: adopt intermediate fre...

Abstract

The invention discloses a processing process of a profiled blind hole flange type inner ball cage fine forging piece with high material utilization. The process comprises the following steps of: taking a raw material; blanking; heating; upsetting; backward extruding; balling and annealing; machining; saponifying with phosphorus; performing; and fine forming. The process has the advantages: in the processing process of the profiled blind hole flange type inner ball cage fine forging piece, a mold cavity part of a flange type inner ball cage is directly forged and pressed into a blind hole form, and the material utilization is improved to more than 90 percent from 75 percent, thereby the consumption of the raw material is greatly reduced, many manufacturing procedures and intermediate links are reduced, the production period is shortened, the manufacturing cost is greatly reduced, and the process provides a condition for quickly occupying the market.

Description

technical field [0001] The invention relates to a processing technology of a special-shaped blind hole flange type inner ball cage precision forging piece. Background technique [0002] The constant velocity universal joint assembly for automobiles is a mechanical component installed between the differential and the hub of the automobile or between the final gear of the gearbox and the hub to transmit power and torque. The input shaft and output shaft of the constant velocity joint assembly transmit motion with an instantaneous angular velocity ratio equal to 1. While transmitting power and torque, it also changes the working angle synchronously, and performs telescopic sliding to compensate for changes in the axial size of the transmission. , and the above functions are mainly realized by the inner ball cage and the outer ball cage in the constant velocity joint assembly. The inner ball cage is an automotive safety component, which has high requirements on its strength, pr...
