Abstract

The invention relates to a flange pipe fork forging forming process and a flange pipe fork formed by using the same. The flange pipe fork forging forming process comprises the following steps of 1, blanking; 2, heating; 3, forging forming; 4, middle hole punching and edge cutting; 5, air cooling; 6, shot blasting; 7, end face turning and mounting hole drilling; 8, fork arm side hole forming; and 9, rust-proof treatment. The flange pipe fork forging forming process has the effect that the flange pipe fork with high coaxial precision can be formed.

Description

technical field [0001] The invention relates to the technical field of shaft yoke processing, in particular to a flange tube yoke forging process and a flange tube yoke formed by the process. Background technique [0002] Tube fork, also known as flange fork, transmission shaft flange fork is an important part of the car, it is the main part connecting the transmission and drive axle and also a part that withstands high-speed transmission. Its structure and processing technology directly affect the performance of the parts, and then affect the power transmission effect of the vehicle. [0003] The existing application announcement number that can be referred to is: CN102107345A Chinese invention patent, which provides a kind of processing method for the flange fork of the universal joint flange of the transmission shaft of heavy-duty vehicles. Through hole, rough turning gear D, F inner hole and inner end surface G; based on the processed inner hole and end surface, rough t...
