Problems solved by technology
However, in the production process, due to factors such as mold pulling force, solid solution high temperature, quenching and rapid cooling, etc., the difference in offset distance H1 (larger or smaller)
Since the offset distance H1 is not easy to measure, during the production process, the distance from the bottom of the rim to the top of the rim is measured, referred to as the concave-convex value H2, and the deviation of the concave-convex value H2 leads to the phenomenon of passing or not reaching the wheel when machining the rim. lead to processing scrap

Embodiment 1
[0020] The present invention provides such Figure 1-3 A hub shaping method shown includes a hub main body 1, a back shaping jig 2 and a front shaping jig 3. The hub main body 1 is composed of a rim 11 and a rim 12, and the rim 12 is arranged on both sides of the rim 11. side, including the following specific shaping steps:
[0021] Step 1: first measure the uneven value H2 between the bottom of the rim 11 and the top of the rim 12, and compare the uneven value H2 with the standard value, and then proceed to step 2, step 3 or step 4;
[0022] Step 2: If the concave-convex value H2 = standard value ± 0.5mm, it means that the hub main body 1 does not need to be reshaped, and the production process is continued;
[0023] Step 3: If the concave-convex value H2 > the standard value, it means that the rim 11 is in a concave state on the hub main body 1, then place the back shaping jig 2 directly under the rim 11, and then place the back shaping jig 2 on the bottom The upward force...

The invention discloses a wheel hub reshaping method, and relates to the technical field of wheel hub reshaping. A reshaping device used in the wheel hub reshaping method comprises a wheel hub body, areverse-side reshaping fixture and an obverse-side reshaping fixture, the wheel hub body is composed of a wheel ring and wheel rims, the wheel rims are arranged on the two sides of the wheel ring. The wheel hub reshaping method comprises the following specific reshaping steps that 1, a bump value H2 between the bottom of the wheel ring and the tops of the wheel rims is measured and compared witha standard value, and then the step 2 and the step 3 or the step 4 are conducted; 2, if the bump value H2 is equal to that the standard value pluses or minuses 0.5 mm, it shows that the wheel hub bodydoes not need to be reshaped, and production machining continues to be conducted; and 3, if the bump value H2 is larger than the standard value, it shows that the wheel ring is in a concave state onthe wheel hub body, and the reverse-side reshaping fixture is arranged under the wheel ring. According to the reshaping method, the process is simple, operation is convenient, the produced wheel hub body with the low precision can be reshaped and reutilized, therefore, the using efficiency of the wheel hub body is improved, and the production cost is saved.
Description
technical field [0001] The invention relates to the technical field of wheel hub shaping, in particular to a wheel hub shaping method. Background technique [0002] The distance from the rim mounting surface to the centerline of the rim is the offset distance H1, and the offset distance H1 is a constant value for each type of rim. However, in the production process, due to factors such as mold pulling force, solid solution high temperature, quenching and rapid cooling, etc., the offset distance H1 is different (larger or smaller). Since the offset distance H1 is not easy to measure, during the production process, the distance from the bottom of the rim to the top of the rim is measured, referred to as the concave-convex value H2, and the deviation of the concave-convex value H2 leads to the phenomenon of passing or not reaching the wheel when machining the rim. Lead to processing scrap. Therefore, it is necessary to invent a hub shaping method to solve the above problems. ...
