Description
Technical field
The utility model belongs to the output shaft former field of wind-power electricity generation, be related to a kind of output shaft of wind-power electricity generation at
Pattern has.
Background technology
The output shaft of existing wind-power electricity generation mostly uses greatly traditional dies forging, as shown in Figure 1, output shaft 100 is T-shaped,
Including pan portion 101 and bar portion 102,101 inside of pan portion is susceptible to irregular circular arc, leads to off-dimension, it is necessary to take out
Mold is refilled after mold is again round as a ball, causes the formed product time long, waste of energy, while also to increase certain altitude surplus,
Raw material are wasted, 102 outer end face of pan portion is easy outbound leg of circuit, and no overlap is easy to hinder mold again, reduces the service life of mold, together
When overlap influence following process clamping, be easily damaged stage property, increase subsequent machining cost.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems, to provide a kind of better wind-power electricity generation of molding effect
Output shaft molding die.
The utility model can be achieved through the following technical solutions：A kind of output shaft molding die of wind-power electricity generation, feature
It is, including external mold, external mold is equipped with perforative stepped hole, and stepped hole includes the path section set gradually from the bottom to top, connection
Section and major diameter section, the path section of the stepped hole is correspondings with the pan portion shape of output shaft, the linkage section of the stepped hole be in it is tapered,
Further include internal model, the shape of internal model is corresponding with the ladder hole shape of external mold, and the internal model is equipped with perforative clear opening, clear opening
It is corresponding with the bar portion shape of output shaft, when internal model is embedded in external mold and is bonded with the stepped hole of external mold, the disk of the output shaft
Portion is molded.
Preferably, it is clearance fit between the internal model and the stepped hole of external mold.
Preferably, the clear opening of the internal model is in up-small and down-big taper.
Compared with prior art, the utility model has following advantageous effect：The output shaft of the utility model wind-power electricity generation at
Pattern has in use, by the bar portion loading internal model of output shaft, and internal model loading external mold is then molded the pan portion of output shaft again, compared with
Existing traditional dies forging can reduce the formed product time, reduce energy consumption, reduce material, reduce lathe process working hour, solution
Certainly occurs the problem of irregular circular arc and pan portion outer end face overlap on the inside of pan portion, synthesis improves outside the qualification rate and product of product
It sees, reduces production cost；In the output shaft molding die of the utility model wind-power electricity generation, the linkage section of external mold stepped hole is in
It is tapered, it on the one hand can play guide support to internal model, on the other hand so that internal model corresponds to external mold stepped hole major diameter section part
Wall thickness increase, improve internal model intensity, reduce the replacement frequency of internal model, reduce cost.

Specific implementation mode
The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 4, a kind of embodiment of the output shaft molding die of wind-power electricity generation, including external mold 1 is set on external mold 1
It includes path section 111, linkage section 112 and the major diameter section set gradually from the bottom to top to have perforative stepped hole 11, stepped hole 11
113, the path section 111 of the stepped hole 11 is corresponding with 101 shape of pan portion of output shaft 100, the linkage section of the stepped hole 11
112 be in tapered, further includes internal model 2, and the shape of internal model 2 is corresponding with 11 shape of stepped hole of external mold 1, and the internal model 2 is equipped with and passes through
The clear opening 21 worn, clear opening 21 is corresponding with 102 shape of bar portion of output shaft 100, when internal model 2 be embedded in external mold 1 in and with external mold 1
Stepped hole 11 when being bonded, the pan portion 101 of the output shaft 100 is molded.
Preferably, it is clearance fit between the internal model 2 and the stepped hole 11 of external mold 1.
Preferably, the clear opening 21 of the internal model 2 is in up-small and down-big taper.
It should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
It is to be appreciated by one skilled in the art that can be modified or replaced equivalently to the technical solution of the utility model, without de-
Objective from technical solutions of the utility model and range should all cover in the right of the utility model.
