Problems solved by technology
[0004] In view of the above-mentioned problems existing in the prior art, it is now intended to provide a process for forging a wheel hub, so that in both the first turning process and the second turning process, there is a finishing allowance at the tire mounting position of the wheel hub. , can ensure its dynamic balance and end diameter jump after finishing turning, improve the product qualification rate, reduce the number of repairs, and at the same time avoid the detection of dynamic balance and end diameter jump after turning, making the whole processing process After the last milling process is completed, the finishing machining of the tread is carried out, and finally the dynamic balance and end diameter jump detection are carried out, which avoids the problems of complicated procedures and low efficiency caused by multiple inspections, and reduces the manufacturing cost.

Embodiment Construction
[0025] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the following examples are combined with the appended figure 1 The technical solutions provided by the present invention are described in detail, but the following content is not intended as a limitation of the present invention.
[0026] figure 1 It is a flowchart of an embodiment of a process for forging a hub of the present invention. Such as figure 1 As shown, the process of the forged wheel hub provided in this embodiment includes the following steps:
[0027] The first step is to obtain the forging billet;
[0028] The acquisition process of forging blanks can be directly outsourced, or the production of blanks can be carried out through the forging process.
[0029] In the second step, the first turning process is carried out, and the inner side of the forged wheel hub and the outer side of the rim are turned, and at the same tim...

The invention provides a process for forging a wheel hub, which belongs to the technical field of accessory manufacturing. A process for forging a wheel hub includes the first step, obtaining forging billet; the second step, performing the first turning process, and at the same time reserving a finishing allowance at the place where the tire is installed; the third step, performing the second turning process , At the same time, reserve a margin for finishing at the place where the tire is installed; the fourth step is to carry out CNC milling modeling; the fifth step is to process the PCD hole and valve hole; the sixth step is to process the CNC milling hole on the back; The seventh step is to finish the finishing machining of the spare margin reserved at the tire mounting place in the second and third steps; the eighth step is to perform dynamic balance and end diameter jump detection on the wheel hub; Deformation leads to the impact of dynamic balance and end diameter jump out of tolerance, which improves product quality and reduces the number of repairs. At the same time, it also avoids the problems of complex procedures and low efficiency caused by multiple dynamic balance and end diameter jump inspections. It reduces the manufacturing cost and is more conducive to the large-scale production and manufacturing of enterprises.
Description
technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a process for forging a wheel hub. Background technique [0002] In the car, the wheel hub is a necessary accessory, and the quality of the wheel hub determines the comfort and safety of the car. Therefore, improving the quality of the wheel hub manufacturing is the direction of current research. [0003] At present, the existing processing technology of the forged wheel hub is to first obtain the forging billet, and then perform the first turning process on the forging billet to realize the turning process on the inner side of the wheel hub and the outer side of the rim, and then perform the second turning process on the forging billet The processing process is to realize the turning process on the outer side of the wheel hub, and after the two-pass machining is completed, the dynamic balance and end diameter jump of the wheel hub are detected, and CNC (English:...
