Description
Technical field
The utility model belongs to frock technical field, more particularly to a kind of transmission axial length necking frock.
Background technology
As shown in Figure 1, necking die is integral design to existing necking die, can not be repaired a die after abrasion, mould
It is higher to have use cost.Necking part mould is made using wolfram steel, increases the rigidity of mould.Can not solve central siphon end face after necking
Enlarging phenomenon.Because straight shelves are shorter after necking, the friction welding technological of major diameter central siphon can not be met.
Utility model content
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of using sectional die
Axial length necking frock is driven, maintenance is conveniently replaceable, completes the technological requirement of the long necking of central siphon, meets production requirement.
The purpose of this utility model is completed by following technical solution, including die holder, the center of described die holder
Inside be sequentially installed with spacer, pressure mouth mold, transition sleeve, reducing die, wherein one end of die holder is provided with limiting plate, the spacer it is spacing
One end of die holder, the end face of the other end of die holder are fixed with pre- the whole series by screw, and this is pre- a whole set of by the spacer in die holder, pressure mouth
Mould, transition sleeve, reducing die are spacing to be fixed；Described spacer, pressure mouth mold, transition sleeve, reducing die, intert in pre- a whole set of center
There are intermediate guide bar and ejector beam, the intermediate guide bar and ejector beam are fixed with each other, and wherein intermediate guide bar is active in
Press mouth mold, transition sleeve, reducing die, it is pre- the whole series in.
Preferably, the internal diameter of described transition sleeve is bigger 0.5MM than the internal diameter size of reducing die.
Preferably, described reducing die, pre- the whole series are made using wolfram steel.
The beneficial effects of the utility model are：By making long necking frock, ensure that product meets drawing requirement, necking end
Length is more than 270mm；Power transmission shaft torsional rigidity is reduced, improves the NVH performances of assembly, while ensure the mode of flexural vibration of power transmission shaft.

Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in Figure 2, the utility model includes die holder
2, it is characterised in that：Spacer 3, pressure mouth mold 4, transition sleeve 5, reducing die 6 are sequentially installed with the center of described die holder 2, wherein
One end of die holder 2 is provided with limiting plate, and the spacer 3 is spacing to pass through screw in one end of die holder 2, the end face of the other end of die holder 2
Pre- a whole set of 7 are fixed with, this is pre- a whole set of 7 by the spacer 3 in die holder 2, pressure mouth mold 4, transition sleeve 5, reducing die 6 is spacing fixes；Institute
The spacer 3 stated, pressure mouth mold 4, transition sleeve 5, reducing die 6, intermediate guide bar 9 and ejector beam 1 are interspersed with pre- a whole set of 7 center,
The intermediate guide bar 9 and ejector beam 1 are fixed with each other, and wherein intermediate guide bar 9 is active in pressure mouth mold 4, transition sleeve 5, contracting
Mouth mold 6, in pre- a whole set of 7, ensure that the concentricity of necking process central siphon 8 meets technological requirement.Pressure mouth mold is provided with frock tail end
4, by the head of central siphon 8 by a certain proportion of necking, pull out ensure that central siphon head sizes meet technique by resilience after mould will
Ask.
The internal diameter of described transition sleeve 5 is bigger 0.5MM than the internal diameter size of reducing die 6, ensures in necking process central siphon 8 not
It is scratched.
Described reducing die 6, pre- a whole set of 7 are made using wolfram steel, ensure also to reduce during necking while precision
Central siphon 8 is scratched or extruded by debris.
The utility model is not limited to above-mentioned embodiment, makees any change no matter being formed in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
