Wheel hub manufacturing device and method

Abstract

The invention discloses a wheel hub manufacturing device and method, and aims at being capable of effectively simplifying a wheel hub manufacturing technology and effectively improving the properties of a wheel hub. The wheel hub manufacturing device comprises a base, the base is provided with guide posts, a fixing plate is fixed to the guide posts, and the guide posts are sleeved with a movable plate which is located between the base and the fixing plate. The base is provided with a bottom mould and side moulds and the side moulds are arranged around the bottom mould. The movable plate is connected with a push rod of a first hydraulic cylinder. The movable plate is provided with a first through hole and second through holes, and a sleeve is arranged on the lower side of the movable plate. The fixing plate is provided with a second hydraulic cylinder, and a push rod of the second hydraulic cylinder penetrates through the first through hole and is connected with a plunger chip mold core. The plunger chip mold core is located in the sleeve and corresponds to the bottom mould. The fixing plate is provided with third hydraulic cylinders, the push rods of the third hydraulic cylinders penetrate through the second through holes and are connected with a flanging mould assembly which is arranged on the periphery of the plunger chip mold core in a sleeving mode and comprises flanging moulds. According to the embodiment of the invention, the wheel hub manufacturing device and method can be applied in manufacturing of wheel hub made of aluminium alloy, magnesium alloy, carbon fiber, a composite material and other materials.

Description

Technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a wheel hub manufacturing equipment and a wheel hub manufacturing method. Background technique [0002] With the development of the automobile industry, the penetration rate of automobiles has increased year by year, and has gradually become a common means of transportation for ordinary families. The popularity of family cars also puts forward higher demands on the performance of cars such as lightweight, safety, handling and environmental protection. [0003] The wheel hub is one of the most important parts of an automobile, and the optimization of the performance of the wheel hub plays a vital role in the optimization of the automobile performance. At present, lightweight structural materials such as aluminum alloys and magnesium alloys have become a better choice for wheel hub materials due to their light weight and high strength. Wheel hubs made of lightweight str...
