Forging wheel forming die and method

Abstract

The invention relates to the technical field of hub forging, in particular to a forging wheel forming die and method, a wheel well part of the forging wheel forming die is designed into a blank according to the shape of a product, the wheel well part is free of metal waste, and smooth demolding can be achieved; side dies are arranged on a lower bottom plate of the die and located on the periphery of the lower die, sliding blocks are connected to the side dies, sliding grooves are formed in angle blocks, the sliding blocks are embedded into the sliding grooves in a sliding mode, third springs are connected between first fixing columns and second fixing columns, pushing mechanisms are arranged on the outer sides of the side dies, and a second shaping block is installed at the lower end of an upper bottom plate. A first shaping block is arranged on the inner side of the second shaping block, a connecting bolt body is connected with the first shaping block, and a first spring sleeves the outer side of the part, located between the upper bottom plate and the first shaping block, of the connecting bolt body; an ejector rod is inserted into an internal T-shaped groove of the first shaping block; a positioning rod is connected with a connecting disc, the part, located in a second stepped hole, of the positioning rod is sleeved with a second spring, the lower end of the connecting disc is connected with a conical body, and a transverse rod penetrates through a through hole in the first shaping block and can make contact with one side of the conical body.

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...
