Abstract

The special-shaped mould of a kind of automotive hub, belongs to metal stamping formed technical field of tools, including the die being coaxially disposed, location mould, punch die and recess mould;Described location mould hollow is arranged, one end sidewall laminating die, the inwall laminating punch die of the other end;Described recess mould is arranged in punch die.The mould of this automotive hub, the defect also completed by trimming for existing simple special-shaped product, use and mould is made special-shaped mould, direct forging molding need not trimming, thus reduces the purpose of production cost.

Description

A kind of special-shaped mould of automotive hub
Technical field
This utility model belongs to metal stamping formed technical field of tools, is particularly related to the special-shaped mould of a kind of automotive hub.
Background technology
At present producing simple heteromorpha forging when, commonly used overlap technique of cutting completes, and overlap filled up by increase material that will necessarily be extra, reduces the utilization rate of material;Owing to many one trimming operations are so production efficiency also reduces.
As shown in Figures 2 and 3, owing to the complexity of automotive hub structure, particularly wheel hub inner ring flange are no longer complete circles, typically having one or more breach, the degree of depth is at below 15mm, and this adds certain difficulty to forging, also improves its production cost.If according to traditional technique, this breach is completed by trimming, then not only needs to increase by one trimming operation, and needs to increase certain spillage of material, improves production cost, lose the advantage of competition.
Utility model content
The purpose of this utility model is to overcome defect mentioned above and deficiency, and provides the special-shaped mould of a kind of automotive hub.
The technical scheme that this utility model realizes the employing of its purpose is as follows.
The special-shaped mould of a kind of automotive hub, including the die being coaxially disposed, location mould, punch die and recess mould;Described location mould hollow is arranged, one end sidewall laminating die, the inwall laminating punch die of the other end;Described recess mould is arranged in punch die.
Described die and punch die are shaped die;Described recess die tip is that semicircle is spherical.
Described die includes the first endoporus, the second endoporus, the 3rd endoporus and the ring flange groove being coaxially disposed;Described second endoporus one end connects the first endoporus, and the other end connects the 3rd endoporus.Described 3rd endoporus mounting flange groove.
The diameter of described second endoporus is more than the first diameter of bore, and the diameter of the second endoporus is less than the 3rd diameter of bore.
The mould of this automotive hub, the defect also completed by trimming for existing simple special-shaped product, use and mould is made special-shaped mould, direct forging molding need not trimming, thus reduces the purpose of production cost.

In figure: 1-die, 1a-the first endoporus, 1b-the second endoporus, 1c-the 3rd endoporus, 1d-ring flange groove, 2-position mould, 3-punch die, 4-recess mould.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in further detail.
The special-shaped mould of a kind of automotive hub, including the die 1 being coaxially disposed, location mould 2, punch die 3 and recess mould 4.
Described location mould 2 hollow is arranged, one end sidewall laminating die 1, the inwall laminating punch die 3 of the other end.Described punch die 3 defines the direction of action of punch die 3 along the inner chamber action of location mould 2, location mould 2.Described recess mould 4 is arranged in punch die 3.
Described die 1 and punch die 3 are shaped die, according to the breach of wheelboss flange the most corresponding be provided with breach.Described location mould 2 plays the effect of fixing die location, otherwise there will be punch die 3 dozens and causes device damage on die 1.And owing to location mould 2 is to arrange around wheelboss flange, direct forging molding need not trimming operation, the most both saved certain material, and also improved production efficiency, and reduced production cost.
Described die 1 includes the first endoporus 1a, the second endoporus 1b, the 3rd endoporus 1c and the ring flange groove 1d being coaxially disposed.
Described second endoporus 1b one end connects the first endoporus 1a, and the other end connects the 3rd endoporus 1c.Described 3rd endoporus 1c mounting flange groove 1d.
The diameter of described second endoporus 1b is more than the first endoporus 1a diameter, and the diameter of the second endoporus 1b is less than the 3rd endoporus 1c diameter.
Described recess mould 4 top is that semicircle is spherical.Recess mould 4 is along punch die 3 inner chamber action, in order to form the recess of wheel hub.
This mould uses the way of straight forming, and the punch die of molding is made the shape the same with product with die, and then by forging directly by the formed product of abnormity, products obtained therefrom is as shown in Figure 4 and Figure 5.
This utility model is illustrated according to embodiment, and on the premise of without departing from present principles, this device can also make some deformation and improvement.It should be pointed out that, the technical scheme that the modes such as all employing equivalents or equivalent transformation are obtained, all fall within protection domain of the present utility model.
