Description
Technical field
The utility model relates to a kind of static iron core.
Background technology
The tooth of existing static iron core upper end surface is all spreading tooth in the market, and spreading tooth to there is productivity ratio low, the defects such as profile of tooth is sharp-pointed, on the other hand in the process that static iron core is shaping, need chip to fall unnecessary material, therefore stock utilization is low, then the cost of static iron core is relatively high.
Utility model content
A kind of structure is simple, intensity is high in order to provide for the utility model, save the static iron core of material.
The utility model is achieved through the following technical solutions:
A kind of static iron core, comprise body, described body is cylindrical, the center that described body is presented axially in described body is provided with a manhole, the lateral wall being positioned at described body two ends is provided with the first conical surface chamfering and the second conical surface chamfering, the scope of the angle α between described first conical surface chamfering and described body axis is between 10 ° ~ 20 °, the scope of the angle β between described second conical surface chamfering and described body axis is between 10 ° ~ 20 °, the end face of described body wherein one end is provided with a circle forged teeth around described manhole, a described circle forged teeth is divergent shape distribution, described manhole is positioned at described forged teeth one end and is provided with a circle having three pyramidal faces chamfering around described manhole.
Described manhole is provided with a circle the 4th conical surface chamfering away from described forged teeth one end around described manhole.
Angle α between described first conical surface chamfering and described body axis is 15 °.
Angle β between described second conical surface chamfering and described body axis is 15 °.
The beneficial effect that the utility model brings is:
In the utility model, described static iron core has the following advantages: overcome the drawback that spreading tooth dentation is sharp-pointed, production efficiency is low, body described in the application is shaping by the mode of forging, therefore the forged teeth shape of end face is mellow and full, Long-Time Service is not easy to damage, and productivity ratio is also relatively high; In addition, the feature in chipless face, also improves the utilance of material.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the upward view of static iron core described in the utility model.
Fig. 2 is the profile of static iron core described in the utility model.
The label that in figure, component names is corresponding is as follows:
1, body; 2, manhole; 3, the first conical surface chamfering; 4, the second conical surface chamfering; 5, forged teeth; 6, having three pyramidal faces chamfering; 7, the 4th conical surface chamfering.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
