Description
Technical field
The utility model relates to a kind of wind power bearing inner ring profiling rings to forge preforming tool.
Background technique
Currently, the preforming of wind power bearing inner ring profiling ring generallys use free base, but because of wind power bearing inner ring size
Span is big, internal diameter 300mm or so bearing inner race imitative type ring forging because amount of rolling it is small, can not pass through to walk completely at intermediate step
Material need to realize that free base can not often assemble enough materials at intermediate step to form by preforming poly- material, from
And make occur lacking material situation at imitative type ring forging intermediate step, additionally due to wind power bearing inner ring profiling ring is needed in free base
Wanting enough upsets, both ends diameter dimension is unanimous on the whole up and down to make blank, so have compressed the sky of specifications of raw materials selection
Between.To sum up, free base has been unable to satisfy the preforming requirement of all wind power bearing inner ring profiling ring forgings, and specifications of raw materials is selected
It selects there are limitation, increases production cost and period.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of wind power bearing inner ring
Profiling ring forges preforming tool, it is conducive to the consistency and stability of blank, improves product quality and production yield.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of wind power bearing inner ring profiling ring forging
Preforming tool, it includes:
Mold base, the type chamber for by bar jumping-up being blank is provided on the mold base, and profiling ring forging at least has
Restricted portion, the type chamber and the shape of the limiting unit of profiling ring forging match；
For being punched out to blank to form the formed punch of profiling ring forging.
It is forged further for the profiling ring for making wind power bearing inner ring profiling ring forging preforming tool be suitable for different height
Part it is preforming, wind power bearing inner ring profiling ring forge preforming tool further include gasket group, the gasket group includes multiple and different
The gasket of height, the gasket are placed on the bottom of type chamber.
Further, the type chamber is horn-like cavity.
Further, the lower section of horn-like cavity is cylindrical, the cross-sectional area of the upper portion of horn-like cavity
It is gradually increased from bottom to top, and the bottom surface of upper portion and the upper bottom surface of the lower section are completely coincident.
Further, it is seamlessly transitted between the upper portion of horn-like cavity and the lower section of horn-like cavity.
Further, the gasket is cylindrical.
After above-mentioned technical proposal, the conventional bar for having enough upsets can be in the intracavitary jumping-up of type of mold base
To certain altitude to form blank, the base material of blank is limited in that type is intracavitary, and then some materials flow to the centre of blank
Position, the effect for crowning and type the chamber limitation that jumping-up itself rises, can make to assemble certain material among blank, then take blank
Out, it is punched out in mold base external application formed punch to carry out the poly- material of the punching of final step, such blank can guarantee slight big
In the case where microcephaly, there are enough crownings in centre；Bar big for specification, without enough upsets, since upset is few, punching
Preceding poly- material is less, and concentric reducer easily occurs, can form blank to specified altitude in the intracavitary jumping-up of type of mold base, then adopt
With directly in the mode of the intracavitary punching of type, during formed punch pushes, blank itself flow to the material of bottom because of type chamber
The middle position of blank is limited and gathered, blank can also be made there are enough crownings, the utility model is conducive to the consistent of blank
Property and stability, and solve internal diameter 300mm or so bearing inner race imitative type ring forging using free base appearance blank
The problem that poly- material is insufficient, and widened space of such imitative type ring forging in specifications of raw materials selection；The pad of the utility model
Piece is designed as different height, so as to be suitable for different height imitative type ring forging it is preforming, it is versatile, saved production money

Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
As shown in Figures 1 to 3, a kind of wind power bearing inner ring profiling ring forges preforming tool, it includes:
Mold base 1 is provided with the type chamber 3 for by bar jumping-up being blank 10, profiling ring forging on the mold base 1
20 at least have limiting unit, and the type chamber 3 and the shape of the limiting unit of profiling ring forging 20 match；
The formed punch 2 of profiling ring forging 22 is formed for being punched out to blank 10.
As shown in Figure 2,3, in order to enable wind power bearing inner ring profiling ring forging preforming tool is suitable for the imitative of different height
Shape ring forging 20 it is preforming, wind power bearing inner ring profiling ring forge preforming tool further include gasket group, the gasket group includes
The gasket 4 of multiple and different height, the gasket 4 are placed on the bottom of type chamber 3.
As shown in Figure 2,3, the type chamber 3 is horn-like cavity.
As shown in Figure 2,3, the lower section of horn-like cavity is cylindrical, in the side wall of the upper portion of horn-like cavity
It is convex.
As shown in Figure 2,3, it is seamlessly transitted between the upper portion of horn-like cavity and the lower section of horn-like cavity.
As shown in Figure 2,3, the gasket 4 is cylindrical.
The working principle of the utility model is as follows:
The conventional bar for having enough upsets, can in the type chamber 3 of mold base 1 jumping-up to certain altitude to form blank
10, the base material of blank 10 is limited in type chamber 3, and then some materials flow to the middle position of blank 10, jumping-up itself
The effect that the crowning and type chamber 3 risen limits, can make to assemble certain material among blank 10, then take out blank 10, in mould
Tool 1 external application formed punch 2 of seat is punched out to carry out the poly- material of the punching of final step, and such blank 10 can guarantee in slight size
In the case where head, there are enough crownings in centre；Bar big for specification, without enough upsets, since upset is few, before punching
Poly- material it is less, and easily there is concentric reducer, blank 10 can be formed to specified altitude by jumping-up in the type chamber 3 of mold base 1, then
Using directly in type chamber 3 by the way of punching, during formed punch 2 pushes, blank 10 flow in itself the material of bottom because
The limitation of type chamber 3 and the middle position for gathering blank 10, can also make blank 10 have enough crownings, the utility model is conducive to
The consistency and stability of blank 10, and solve imitative type ring forging 20 of the internal diameter in 300mm or so bearing inner race using freely
The problem that the poly- material of the blank 10 that base occurs is insufficient, and widened sky of such imitative type ring forging 20 in specifications of raw materials selection
Between；The gasket 4 of the utility model is designed as different height, so as to be suitable for different height imitative type ring forging 20 it is preforming,
It is versatile, save resources of production.
Particular embodiments described above, to the utility model solve the technical issues of, technical scheme and beneficial effects into
It has gone further description, it should be understood that the foregoing is merely specific embodiment of the utility model, and has not had to
In limitation the utility model, within the spirit and principle of the utility model, any modification, equivalent substitution and improvement done
Deng should be included within the scope of protection of this utility model.
