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

[0028] see in conjunction Figure 1 to Figure 8 As shown, according to the embodiment of the present application, the wheel hub forming device 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 core 1 and is arranged on the lower mold part. A plurality of combined dies 2 on the outer peripheral side of the mold core 1, the combined dies 2 are movable along the direction close to or away from the lower die core 1, when the combined dies 2 are combined, they cooperate with the lower die core 1 Form the lower mold cavity.

[0029] 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 plurality of comb...

Abstract

The invention provides a hub forming device. The hub forming device comprises an upper mold part and a lower mold part, a hub extrusion mold cavity is formed between the upper mold part and the lower mold part, the lower mold part comprises a lower mold core (1) and multiple combined female molds (2) arranged on the periphery side of the lower mold core (1), the combined female molds (2) are movably arranged in the direction close to or away from the lower mold core (1), and when the combined female molds (2) are combined together, the combined female molds are matched with the lower mold core (1) to form a lower mold cavity. According to the hub forming device, the production procedure can be simplified, forming efficiency is improved, and production cost is reduced.

Description

technical field [0001] The application belongs to the technical field of extrusion forming, and in particular relates to a wheel hub forming device. 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...
