CN205056767U - To forging wheel that revolves that embryo carries out spinning - Google Patents

Abstract

The utility model provides a to forging wheel that revolves that embryo carries out spinning, include: first wheel soon and second revolve the wheel, the first front end that revolves the wheel has a chopper, be used for with it cleaves and imbeds wherein to forge the both ends of embryo, first rear end of revolving the wheel with the second revolves the wheel interlock to be connected, first wheel soon and second revolve the wheel and carry out spinning to forging the embryo jointly, will thereby the embryo that revolves of H shape is expanded to form in the both ends of forging the embryo by cleft partial spinning. The utility model provides a to forging wheel that revolves that embryo carries out spinning: because the first both ends of revolving the wheel embedding and forging the embryo. Then, use the second to revolve the wheel and drive the first wheel that revolves and carry out spinning to the both ends of forging the embryo jointly, resistance greatly reduced when spinning takes shape, having lengthened the consume while of revolving the life and the equipment of wheel, the process of spinning is more stable, and the product percent of pass improves greatly.

Description

A kind of spinning roller forging embryo being carried out to spinning

Technical field

The utility model relates to aluminum-alloy wheel forging line technical field, particularly relates to a kind of spinning roller forging embryo being carried out to spinning.

Background technology

Carrying out spinning to forging embryo generally uses a spinning roller to forging embryo, and spinning roller is spinning from the outer surface of forging embryo, and the power required for spinning is very large.The service life of spinning roller and the consume of equipment all larger.Further, during spinning, material flow forming has some setbacks, and easily produce the defect of potential folded material, the process of spinning is stable not, and product percent of pass is not high enough.

Utility model content

The utility model provides kind of spinning roller forging embryo being carried out to spinning, which overcomes the deficiencies in the prior art described in background technology.

In order to solve above-mentioned technical problem, the utility model provides a kind of spinning roller forging embryo being carried out to spinning, comprising: the first spinning roller and the second spinning roller;

The front end of described first spinning roller has a chopper, for being rived at the two ends of described forging embryo and embedding wherein; Rear end and described second spinning roller of described first spinning roller are connected;

Described first spinning roller and the second spinning roller carry out spinning to forging embryo jointly, the two ends of described forging embryo are launched by the part spinning of riving thus form H-shaped revolve embryo.

Compared to prior art, the technical solution of the utility model possesses following beneficial effect:

The utility model provides a kind of spinning roller forging embryo being carried out to spinning:

Front end due to the first spinning roller has a chopper, is rived, and embed wherein by the two ends of sharp chopper by forging embryo.Then, the second spinning roller is used to drive the first spinning roller jointly to carry out spinning to the two ends of forging embryo.Because the first spinning roller embedded in the two ends of forging embryo, the resistance therefore during mould pressing greatly reduces, and extends the service life of spinning roller and the consume of equipment.

Meanwhile, the power that the mould pressing having shared the second spinning roller due to the first spinning roller needs, when making spinning, material flow forming is more smooth and easy, and not easily produce the defect of potential folded material, the process of spinning is more stable, and product percent of pass improves greatly.

Accompanying drawing explanation

Fig. 1 is the structural representation in the utility model preferred embodiment, forging embryo being carried out to the spinning roller of spinning;

Fig. 2 revolves embryo schematic diagram after forging embryo rotary press modelling.

Detailed description of the invention

Hereafter with detailed description of the invention, the utility model is described further by reference to the accompanying drawings.

Consult Fig. 1-2, a kind of spinning roller forging embryo being carried out to spinning, comprising: the first spinning roller 1 and the second spinning roller 2;

The front end of described first spinning roller 1 has a chopper 11, for being rived at the two ends of described forging embryo 3 and embedding wherein; Rear end and described second spinning roller 2 of described first spinning roller 1 are connected;

Described first spinning roller 1 and the second spinning roller 2 carry out spinning to forging embryo 3 jointly, the two ends of described forging embryo 3 are launched by the part spinning of riving thus form H-shaped revolve embryo 4.

Front end due to the first spinning roller 1 has a chopper 11, is rived, and embed wherein by the two ends of sharp chopper 11 by forging embryo 3.Then, the second spinning roller 2 is used to drive the first spinning roller 1 jointly to carry out spinning to the two ends of forging embryo 3.Because the first spinning roller 1 embedded in the two ends of forging embryo 3, the resistance therefore during mould pressing greatly reduces, and extends the service life of spinning roller and the consume of equipment.

Meanwhile, the power that the mould pressing having shared the second spinning roller 2 due to the first spinning roller 1 needs, when making spinning, material flow forming is more smooth and easy, and not easily produce the defect of potential folded material, the process of spinning is more stable, and product percent of pass improves greatly.

The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
