A kind of forging wheel forming die and method

Abstract

The invention relates to the technical field of wheel hub forging, in particular to a forging wheel forming die and method, wherein the wheel well part is designed with a blank according to the shape of the product to ensure that there is no metal waste in the wheel well part and can achieve smooth demoulding; Side molds are set around the mould, sliders are connected to the side molds, chutes are set on the corner blocks, the sliders slide and embedded in the chute, the spring 3 is connected between the fixed column 1 and the fixed column 2, and the outside of the side mold is set to push Mechanism, the shaping block 2 is installed at the lower end of the upper base plate; the shaping block 1 is arranged on the inner side of the shaping block 2, the connecting bolt body is connected with the shaping block 1, and the outer part of the connecting bolt body located between the upper base plate and the shaping block 1 is sleeved with a spring 1. The ejector rod is inserted into the inner T-shaped slot of the shaping block 1; the positioning rod is connected with the connection plate, and the part of the positioning rod located in the second stepped hole is sleeved with a spring 2. The lower end of the connection plate is connected with a cone, and the cross bar passes through Through the through hole on the shaping block one and can be in contact with one side of the cone.

Description

technical field [0001] The invention relates to the technical field of wheel hub forging, in particular to a forging wheel forming die and method. Background technique [0002] The conventional forming steps of forged aluminum alloy wheels are forging, reaming, and spinning, and the same is true for deep wheel well products. As we all know, when forging aluminum alloy wheels, the forging mold moves vertically up and down along the axis, so the mold must have a draft angle in the vertical direction to ensure that the forged blank can be taken out smoothly. Obviously, the forged wheel with deep wheel well structure cannot directly forge the deep wheel well part during forging; and the metal in the deep wheel well part cannot be unscrewed and utilized by spinning during the spinning step. The existing production method causes the waste of this part of the rough metal, which affects the metal yield and wastes the cost. Contents of the invention [0003] In order to solve the...
