Problems solved by technology

[0003] At present, most of the magnesium alloy wheels prepared by plastic forming technology first adopt the process of forming blanks in multiple passes, and then cutting and surface treatment. Even if the process of centralized process (one-time forming) is adopted, the utilization rate of materials is still extremely low ( <40%), large equipment tonnage, high production costs and other bottlenecks restricting the marketization of magnesium alloy wheels, which cannot meet the requirements of multi-variety, large-volume, and low-cost production of this type of parts

Embodiment Construction

[0041] see in conjunction Figure 1 to Figure 8 As shown, according to the embodiment of the present application, the hub forming device used in the hub forming method includes an upper mold part and a lower mold part, and a hub extrusion cavity is formed between the upper mold part and the lower mold part, and the lower mold part includes a lower mold Die core 1 and a plurality of combined dies 2 arranged on the outer peripheral side of the lower die core 1, the combined dies 2 are movable along the direction approaching or away from the lower die die core 1, when the combined dies 2 are combined together, The lower mold core 1 cooperates to form the lower mold cavity.

[0042] When the wheel hub forming device is forming the wheel hub, the forming and ejection of the extrusion die can be realized through the movement of the combined die 2. When the wheel hub needs to be extruded, the combined die 2 can be controlled to move closer to the core of the lower die. 1, and make a...

Abstract

The invention provides a hub forming method. The hub forming method comprises the steps that annular blank is selected as a processing raw material; the annular blank is subjected to forward extrusion forming, and performing of a spoke and a rim of a hub is simultaneously completed at one step; the preformed annular blank is subjected to flaring of the rim and flange forming of a wheel flange; and the spoke of the hub is subjected to shrinkage and precise forming. According to the hub forming method, the production procedure can be simplified, the forming efficiency can be improved, the material utilization rate can be increased, and the production cost can be reduced.

Description

technical field [0001] The application belongs to the technical field of extrusion forming, and in particular relates to a wheel hub forming method. Background technique [0002] Magnesium alloy wheels have become the main form of wheels in the future development trend of the automotive industry because of their light weight and high strength, superior shock absorption performance, and important impact on energy conservation. main route of the file. [0003] At present, most of the magnesium alloy wheels prepared by plastic forming technology first use multi-pass forming blanks, and then cutting and surface treatment process. Even if the process of centralized process (one-time forming) is adopted, the utilization rate of materials is still extremely low ( <40%), large equipment tonnage, high production cost and other bottlenecks restricting the marketization of magnesium alloy wheels, which cannot meet the requirements of multi-variety, large-scale, and low-cost product...
