Problems solved by technology

[0003] At present, the methods of manufacturing aluminum alloy wheels at home and abroad are mainly divided into two categories: one is forging, and the other is casting. However, the casting method products have serious defects such as shrinkage cavity, porosity, and pores, low mechanical strength, and low yield. , foreign countries have basically eliminated
Traditional forging dies adopt integral structure, and each type of wheel hub must correspond to a pair of dies, so the storage space, management, maintenance and manufacturing costs of the dies are very huge, and the dies that have been placed for a long time are very easy to damage, and when After the overall structural mold is damaged by pressing, it is necessary to replace the upper and lower molds as a whole, and the replacement cost is also very huge, which is labor-intensive, time-consuming and material-intensive, and increases the production cost of aluminum alloy wheels, resulting in a great waste of resources

Embodiment 1

[0034] Example 1, a wheel hub forging die, see attached figure 1 , Including upper mold 2 and lower mold 1. For the structure of upper mold 2, please refer to the attached figure 2 , Including upper template 21, upper mold body 22, upper mold core 23 and upper mold ejector 24, see attached image 3 , The upper mold body 22 passes through the fifth countersunk hole 211 through the fifth countersunk bolt 75 and then is locked on the upper template 21, see Appendix Figure 4 with 5 , A circular protrusion 231 is provided at the upper mold core 23, a circular recess 222 is provided at the upper mold body 22, and the upper mold body 22 and the upper mold core are realized by the cooperation of the circular protrusion 231 and the circular recess 222 23 is installed and positioned, and the upper mold body 22 and the upper mold core 23 are locked and fixed by the first countersunk bolt 71 (first locking member) passing through the first countersunk hole 221 (first avoidance structure) ....

Embodiment 2

[0038] Example 2, a wheel hub forging die, is different from Example 1 in that, see Appendix Picture 10 At this time, the thickness of the ring insert 5 will be less than the depth of the recessed ring groove 4, that is, the rim width of the hub when finally forged will be greater than the rim width in Embodiment 1, and the ring insert 5 can be replaced Thickness (not exceeding the groove depth of the recessed ring groove 4), the width of the hub rim after the final forging can be changed. When the ring insert 5 is replaced, an unsealing screw (not shown in the figure) is screwed into the unsealing threaded hole 61. Push the ring insert 5 out of the recessed ring groove 4, then replace the required thickness of the ring insert 5 into the recessed ring groove 4, and fix the ring insert 5 in the recessed ring by the second countersunk bolt 72 Slot 4.

Embodiment 3

[0039] Example 3, a wheel hub forging die, differs from Example 1 in that, see Appendix Picture 11 , The ring insert 5 is not placed in the recessed ring groove 4, that is, the width of the rim of the forged hub at this time will be equal to the ring cavity 3 plus the depth of the recessed ring groove 4, which can be forged when designing the mold The maximum rim width value.

Abstract

The invention discloses a hub forging die which comprises an upper die and a lower die. The upper die comprises an upper die plate and an upper die body installed on the upper die plate. The upper die body is detachably connected with an upper die core. A locating structure capable of matching the upper die body with the upper die core and a locking structure capable of locking the upper die body and the lower die core are arranged between the upper die core and the upper die body. The upper die body and the upper die core are arranged to be of a split structure, the upper die core and the upper die body are detachably connected and fixed, and therefore hubs with different spoke shapes can be forged through one die simply by replacing the upper die core.

Description

Technical field [0001] The invention relates to the field of forging, and more specifically, it relates to a die for forging an aluminum alloy wheel hub. Background technique [0002] The world's automobile industry is developing in the direction of light weight, high speed, safety, energy saving, comfort and light environmental pollution. Therefore, the use of aluminum alloy parts in automobiles is increasing. As one of the important components in the automobile driving system, the wheel hub is also a kind of high-demand security part. It not only bears the weight of the automobile, but also reflects the appearance of the automobile. In the past 10 years, the average annual growth rate of global aluminum alloy automobile wheel production reached 7.6%. [0003] At present, the methods of manufacturing aluminum alloy wheels at home and abroad are mainly divided into two categories: one is forging and the other is casting. However, the casting method has serious defects such as shri...
