Forging die for formed hub

Abstract

The invention relates to the technical field of dies, and discloses a forging die for a formed hub. The forging die comprises an upper die and a lower die, the lower die comprises a lower die plate, a lower die core installed on the lower die plate and a lower die body fixedly connected to the lower die core in a sleeving mode, the upper die comprises an upper die plate and an upper die core located over the lower die core, a forging cavity is formed among the upper die core, the lower die core and the lower die body during die assembly, the lower die body comprises at least two die body assemblies which can be far away from the lower die core or form a circular closed ring to be attached to the outside of the lower die core after being attached to each other, the die body assemblies get close to each other or get away from each other under the control of a first driving mechanism, a tightening ferrule clamped outside the attached die body assembly during die closing is vertically arranged on the upper die plate in a lifting mode, and lifting of the tightening ferrule is controlled by a second driving mechanism fixed to the upper die plate. The die remarkably improves demolding convenience after hub forging, raw material waste caused in the forging stage is remarkably reduced, and subsequent blank spinning procedures are reduced, so that the production cost of the hub is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a forging mold for forming a wheel hub. Background technique [0002] At present, the methods of manufacturing aluminum alloy wheels at home and abroad are mainly divided into two categories: one is forging method, and the other is casting. The rate is low, and foreign countries have basically eliminated it. [0003] The structure of a traditional forging die can refer to a wheel hub forging die disclosed in a Chinese patent with the notification number CN106238647A, which includes an upper die and a lower die, and the lower die includes a lower die, a lower die body mounted on the lower die and a lower die core , the lower mold core includes a forging core part and a base part below the forging core part, an annular ring cavity for forging a rim is formed between the forging core part and the lower mold body, and a ring along the ring is provided on the base part. A concave ring...

Problems solved by technology

[0005] Aiming at the problem in the prior art that it is difficult to remove the forged hub, which leads to an increase in the thickness of the hub, thereby increasing the subsequent material cost, labor cost and mechanical cost, the purpose of the present invention is to provide an easy-to-remove hub that reduces the forged thickness of the spoke Die forming wheel hub forging die
