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 process for manufacturing an automobile half shaft, comprising the following steps:

[0019] (1) Raw material: Cut a certain length of steel bar with the same thickness as the half shaft rod as the raw material of the half shaft (such as figure 1 shown); select the flange blank as the raw material of the flange (such as figure 2 shown);

[0020] (2) Flange finishing: Turn the flange blank, process the positioning reference plane and clamping position required for precision drilling on the flange surface, and then drill 1, chamfer and drill the center hole 2 (such as image 3 shown);

[0021] (3) Friction crimping: crimp the finished flange and half shaft raw materials into a whole automobile half shaft through friction crimping equipment (such as Figure 4 shown);

[0022] (4) Machining of half shafts: Turn the whole half shaft, twist the splines, heat the whole half shaft to 750-890 ℃ through the intermediate frequency equipment for heat treatment, and then spra...

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 technology of shaft parts, in particular to a manufacturing technology of an automobile half shaft. Background technique [0002] At present, the common machining process 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 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. Spinning the shaft end spline; 5. Intermediate frequency heat treatment and low temperature tempering; 6. Straightening, flange finishing; 7. Grinding the outer diameter; 8. Precise drilling and chamfering of the flange surface. The length and volume of the workpiece are relatively large when the whole rod shaft is formed and then processed. Correspondingly, it is necessary to increase the type of e...
