Embodiment Construction

[0037] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0038] like Figure 1 to Figure 9 As shown, a powerful spinning demoulding mechanism for an aluminum alloy wheel includes a mandrel structure. The mandrel structure includes an inner core film 6 and an outer mandrel sleeved outside the inner core film 6. Locked and fixed confinement block 4 with the outer mandrel moving radially under force, and a position-limiting telescopic mechanism for pushing the structure of the mandrel to move and driving the outer mandrel away from the confinement block.

[0039] The limit telescopic mechanism includes a limit rod 2 and a spring 3 located in the guide cha...

Abstract

The invention discloses an aluminum alloy hub powerful spinning machining molding method and a demolding mechanism. The demolding mechanism comprises a core mold structure which comprises an inner core mold and an outer core mold connected to the exterior of the inner core mold in a sleeving manner, and the demolding mechanism further comprises a suppressing block and a limiting stretching mechanism, wherein the suppressing block and the outer core mold which is stressed to move in the radial direction are fixedly locked, and the limiting stretching mechanism is used for pushing the core mold structure to move and driving the outer core mold to separate from the suppressing block. The machining molding method comprises the steps that a plate is jacked to the core mold structure through a tail jacking part to be fixed, the inner core mold is extruded, and the outer core mold is stressed to move in the radial direction to be matched and locked with the suppressing block; the core mold structure is rotated to drive the tail jacking device and the plate to rotate; and hub molding is carried out through a multi-wheel spinning process. By means of the aluminum alloy hub powerful spinning machining molding method and the demolding mechanism, the problem that demolding is difficult after complex section hub spinning molding is solved, the demolding principle is simple, and universality is high.

Description

technical field [0001] The invention belongs to the technical field of spinning wheel pressure processing, and in particular relates to a powerful spinning forming method of an aluminum alloy wheel hub and a demoulding mechanism. Background technique [0002] With the increasingly stringent safety and environmental regulations, in the automobile manufacturing industry, the requirements for weight reduction and energy saving are also increasing. The innovation of materials and processing technology is the key to realize the lightweight of automobiles. Car hubs play many roles such as carrying the weight of the vehicle, associating steering and driving, and reflecting the appearance of the vehicle. The structure and manufacture of the wheel hub have an important impact on the energy saving, environmental protection and safety performance of the car. At present, the forming methods of aluminum alloy wheels mainly include casting method, forging method and spinning method. Th...
