Forging forming device for automobile hub and using method thereof

Abstract

The invention relates to a forging forming device for an automobile hub and a using method of the forging forming device. When the automobile hub is manufactured, a hub blank is heated and then placedin a pre-forging cavity of a pre-forging lower die; a second hydraulic cylinder drives a floating die holder to move upwards to the position above the lower die holder; a first hydraulic cylinder drives the lower die holder to move so that the pre-forging cavity can right face an upper die core. the second hydraulic cylinder drives the floating die holder to move downwards, so that two separabledie rings surround the edge of the pre-forging lower die and are combined with the pre-forging cavity; a press drives the upper die core to forge and press downwards, so that the hub blank is preformed; then, the second hydraulic cylinder drives the floating die holder to drive the preformed hub to move upwards to the position above the lower die holder; the first hydraulic cylinder drives the lower die holder to move so that a finish forging cavity can right face the upper die core; the second hydraulic cylinder drives the floating die holder to move downwards so that the preformed hub can beplaced in a middle section die cavity; and the press drives the upper die core to forge downwards, so that the hub blank is finally formed.

Description

technical field [0001] The invention relates to a forging forming device of an automobile wheel hub and a using method thereof, belonging to the technical field of forging. Background technique [0002] The forming methods of light alloy wheels such as aluminum and magnesium for automobiles mainly include casting and spinning methods and forging and spinning methods. That is, casting + spinning method and forging + spinning method. Forged wheels are significantly better than cast wheels in terms of weight reduction, dimensional accuracy, strength, toughness and fatigue life. With the increasingly urgent demand for lightweight, high-speed and safety of automobiles, forged wheels will definitely become an upgraded product of cast wheels and have a huge market prospect. In order to efficiently and economically obtain forged wheels with excellent mechanical properties, many new methods and devices have been proposed. Although the wheels made by the forging method have good str...

In order to efficiently and economically obtain forged wheels with excellent mechanical properties, many new methods and devices have been proposed. Although the wheels made by the forging method have good structure and mechanical properties, they all have complex production processes, low efficiency and low cost. High, more equipment required, large investment and other issues, can not well meet the requirements of industrial production
