Abstract

The invention relates to the technical field of transmission shaft production, and discloses a forging process of an energy-saving rear spline shaft. The forging process of the energy-saving rear spline shaft comprises the steps of (1) preparing materials: preparing a blank; (2) heating: heating the heating section of the blank prepared in the step (1); (3) forming: putting the blank heated in thestep (2) into a mold for forging; (4) demolding: withdrawing an upper mold, and ejecting the blank; and (5) inspection: inspecting the product manufactured in the step (4). According to the energy-saving rear spline transmission shaft forged by the process, the blanking weight can be reduced, energy is saved, the quality is improved, and the cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of transmission shaft production, in particular to an energy-saving rear spline shaft forging process. Background technique

[0002] The transmission shaft is an important part of power transmission in the car transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the car can generate driving force. The transmission shaft is composed of a shaft tube, a telescopic sleeve and a universal joint, and the telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle. The universal joint is to ensure the change of the angle between the output shaft of the transmission and the input shaft of the drive axle, and to realize the transmission of the two shafts at equal angular speeds.

[0003] The spline shaft is a kind of mechanical transmission. Its structure is that there are longitu...
