Problems solved by technology

[0005] (1) Using the sawing method will produce a lot of waste aluminum scraps, causing a certain waste of raw materials;
[0006] (2) The whole aluminum plate is sawed in a criss-cross manner, and the processing time is long;
[0007] (3) After cutting into cubes of the designed size, it is transported and preheated. There are many process steps, which increases the process time.

Embodiment 1

[0037] Embodiment 1, a kind of wheel hub forging method, see appendix figure 1 , which is mainly divided into several major steps of material preparation, forging, spinning, heat treatment and machining. Based on a 17-inch aluminum alloy wheel hub, the 7A04 aluminum alloy extruded plate with a thickness of 65mm is thermally cut to a size of 350mm ×350mm×65mm square blank;

[0038] The material preparation stage is a continuous production process in this embodiment, a. After the aluminum rod is melted and cast, an aluminum alloy plate of 350mm×65mm is extruded by an extruder; b. The extruded aluminum alloy plate is conveyed online into the preheating The furnace is heated to 440°C, and preheated for 30 minutes; c. One end of the preheated aluminum alloy plate coming out of the furnace is placed on the supporting mechanism, and the hydraulic cutter at the outlet of the furnace directly cuts the preheated aluminum alloy. On-line hot cutting, the cut billet will fall directly to ...

Abstract

The invention discloses a hub forging method which comprises the following steps: a. profile extrusion: extruding an aluminum alloy plate with set thickness and width by an extruding machine; b. preheating: continuously online heating the aluminum alloy plate extruded by the extruding machine through heating equipment; c. hot cutting: cutting the preheated aluminum alloy plate which goes out from the heating equipment into a preset length to form a square-shaped blank by adopting the hot cutting technology; d. forging: putting the blank after being hot cut into a die, and forging and pressing the blank to form a disk shape; e. punching and bulging the disk-shaped blank; f. putting an enamel blank after being punched and bulged into a spinning machine, and carrying out spinning forming; and g. carrying out heat treatment and machining on the enamel blank after spinning forming to obtain a finished hub product. With adoption of the hub forging method, the efficiency of forging the hub, the utilization ratio of a raw material and the density of a product are higher.

Description

technical field [0001] The invention relates to the field of forging, more specifically, it relates to a forging method for forging an aluminum alloy wheel hub. Background technique [0002] The world's automobile industry is developing in the direction of light weight, high speed, safety, energy saving, comfort and less environmental pollution, so the amount of aluminum alloy parts used in automobiles is increasing day by day. As one of the important parts in the driving system of the car, the wheel hub is also a kind of security device with high requirements. It not only bears the weight of the car, but also reflects the appearance of the car. In the past 10 years, the average annual growth rate of the global aluminum alloy automobile wheel production has reached 7.6%. It can be seen that with the increasing demand for lightweight automobiles, aluminum alloy wheels are gradually replacing traditional steel wheels in modern automobile manufacturing and are widely used. ...
