Multi-station forging device for automobile aluminum alloy hub

Abstract

The invention discloses a multi-station forging device for an automobile aluminum alloy hub. The multi-station forging device for the automobile aluminum alloy hub comprises an upper die assembly and a lower die assembly, wherein the lower die assembly is provided with multiple forging stations; the upper die assembly and the forging stations of the lower die assembly are matched to complete multiple forging procedures; the upper die assembly comprises an upper die plate, an upper die, a die frame, a spring seat, a discharging ring and a pair of half die ring separating and combining parts; the lower part of the upper die plate is fixedly connected with an upper die base; the upper die is arranged on the lower surface of the upper die base; the die frame is arranged below the upper die plate and located outside the upper die base; the spring seat is arranged between the upper die seat and the die frame; a first reset spring is arranged in the spring seat; the discharging ring is arranged on the outer side of the upper die base and connected to the lower surface of the spring seat; the pair of half die ring separating and combining parts are symmetrically arranged on the two sides of the lower part of the die frame; each half die ring separating and combining part is provided with a half die; and the two half dies are combined in an opposite mode to form a half die ring, and a cavity is formed between the half die ring and the upper die.

Description

technical field [0001] The invention relates to the field of automobile molds, in particular to a multi-station forging device for an automobile aluminum alloy wheel hub. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft, also called the wheel rim, steel ring, wheel, tire bell, it is an indispensable part of the car . [0003] The traditional aluminum alloy wheel manufacturing process is to die-cast an aluminum alloy wheel blank by a die-casting machine, such as figure 1 Shown: Blank with spokes and part of rim, no rim. Flared after the blank (see figure 2 ), spinning (see image 3 ) to form a complete hub. The disadvantage of this process is that the process is complicated. It needs to melt the aluminum material to die-cast a blank, then use a press to expand the rim, and then use a spi...
