[0018] A manufacturing process for automobile half shafts, which is characterized in that it comprises the following steps:
[0019] (1) Raw material: cut a certain length of steel rod with the same thickness as the half shaft as the raw material for the half shaft (such as figure 1 Shown); select flange blanks as the raw material of the flange (such as figure 2 Shown);
[0020] (2) Flange finishing: turning the flange blank, processing the positioning reference surface and clamping position required for precision drilling of the flange surface, and then drilling 1, chamfering and drilling center hole 2 (such as image 3 Shown);
[0021] (3) Friction crimping: the finished flange and the semi-shaft raw materials are crimped into the whole automobile semi-shaft (such as Figure 4 Shown);
[0022] (4) Half-shaft processing: Turn the whole half-shaft, rub the spline, heat it to 750-890℃ by the intermediate frequency equipment, and then spray water to cool it to reach the required hardnes...
