Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub pre-processing-free spinning device. Background Art

[0002] Conventional wheel hub molding is generally carried out by casting, but casting not only consumes a lot of energy, wastes a lot of energy, and has poor production precision, but also requires multiple subsequent processing of the cast wheel hub. In addition, the wheel hub produced by casting is prone to bubbles, uneven wheel density, and insufficient surface smoothness. The wheel hub needs to be subsequently processed, which not only increases production costs, production steps and labor intensity, but also easily causes quality problems of the wheel hub.

[0003] Aluminum alloy wheel hub spinning technology has gradually developed in China in recent years, but the production process of this technology has always been complicated. The existing technology process is: casting blank - cutting riser - machining roughening - spinning. There are many process steps and it is difficult to increase production.

[0004] Therefore, in view of the above technical problems, it is necessary to propose a wheel hub spinning device without pre-processing. Utility Model Content

[0005] The purpose of the utility model is to provide a hub spinning device without pre-processing to solve the problems raised in the above background technology.

[0008] Preferably, the hub loading rotating platform comprises a rotating motor and a rotating frame, and an output end of the rotating motor is fixed to the rotating frame.

[0009] Preferably, the clamping mechanism comprises a hydraulic cylinder and a clamping head, and an output shaft of the hydraulic cylinder is connected to the clamping head.

The hub product design of the utility model is refined, the exhaust groove is cancelled in the upper mold, and the taper of the water inlet of the side mold is adjusted. It can be completely separated from the product after the casting machine is removed and does not protrude from the product surface. The side mold closing position is the position that is most likely to thicken the product thickness and form uncertainty for the product. The structure of the side mold is adjusted to enhance its strength. It will not deform or open in a high temperature environment, thereby ensuring the stability of the product spinning line. After multiple batches of tests, the design requirements are fully met. After the hub of the utility model is cast and formed, the riser is cut and spun directly, which reduces mechanical roughening and improves the hub processing efficiency.
