Problems solved by technology

After the whole rod shaft is formed and then processed, the length and volume of the workpiece are relatively large. Correspondingly, it is necessary to increase the size of the equipment to complete the processing of the workpiece, thereby increasing the cost of the equipment; Clamping, positioning and drilling are easy to deviate, and the process of loading and unloading is also very inconvenient

specific Embodiment approach

[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...

Abstract

The invention discloses a manufacturing process of an automobile half shaft. The manufacturing process comprises the following steps of (1) preparing raw materials, (2) conducting finish machining on a flange, (3) conducting friction and crimping, (4) conducting half shaft machining and (5) conducting half shaft finish turning grinding and rustproof packaging. Hole drilling, chamfering and center hole drilling of a flange rough blank are carried out before a flange blank and a rod shaft are crimped, and the crimping is carried out after machining is finished. The manufacturing process solves the problem of location degree deviation of a flange coordinate and the hole position of the whole automobile half shaft, and accuracy is accurate. The flange shape is small before crimping, a common center machine can meet requirements for the flange to drill the hole, cost of equipment is reduced, simultaneously, material feeding and discharge are fast, and production efficiency and percent of pass can be greatly improved.

Description

Technical field [0001] The invention relates to the field of manufacturing process of shaft parts, in particular to a manufacturing process of an automobile half shaft. Background technique [0002] At present, the common processing technology of automobile half-shaft is to crimp the flange blank and bar material into a whole automobile half-shaft through special friction crimping equipment, and then process it. The specific manufacturing process is: 1. Drilling the center hole at the shaft end; 2. Drilling the center hole at the flange end; 3. Turning the shape of the entire half shaft; 4. Rotating the shaft end spline; 5. Intermediate frequency heat treatment and low temperature tempering; 6. Straightening, flange precision turning; 7. Grinding outer diameter; 8. Precision drilling and chamfering of flange surface. The entire rod shaft is processed after it is formed. The length and volume of the workpiece are relatively large. Correspondingly, it is necessary to increase the ...
