Description
Technical field
The utility model relates to a kind of static iron core of improvement.
Background technology
At present, the static iron core parts that market occurs, there is most machine work face in its surface, on the one hand, be that insufficient strength is high, 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 the static iron core improved 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 the improvement of material.
The utility model is achieved through the following technical solutions:
A kind of static iron core of improvement, comprise body, the lateral wall of described body is provided with a circle block reinforcement, described body is provided with a cylindrical boss away from the end face of described block reinforcement one end, described cylindrical boss side is provided with a truncated cone-shaped boss, described body is provided with two symmetrical rectangular apertures and " U " shape opening, described two rectangular apertures and " U " shape opening are positioned at outside described cylindrical boss, described body is positioned at described body central place and is provided with the first manhole on axis, second manhole and the 3rd manhole, described first manhole is near described block reinforcement one end, be connected by a taper surface transition between described first manhole with described second manhole, the diameter of described first manhole is greater than the diameter of described 3rd manhole, the diameter of described 3rd manhole is greater than the diameter of described second manhole, described block reinforcement is provided with an arc-shaped notch.
The tapering α scope of described truncated cone-shaped boss is between 55 ° ~ 85 °.
The tapering α of described truncated cone-shaped boss is 70 °.
A circle first circular arc chamfering is provided with between described first manhole outer end and described body end face.
Described first manhole the inner is provided with a circle second circular arc chamfering.
Described 3rd manhole the inner is provided with a circle three-arc shape chamfering.
The beneficial effect that the utility model brings is:
In the utility model, the static iron core of described improvement has the following advantages: adopt repeatedly forging method, additional essence punching, thus obtains high strength, high stock utilization, and make the forging plane of the static iron core surface area of improvement reach more than 95%, therefore there is relatively high intensity; 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 right view of the static iron core of improvement described in the utility model.
Fig. 2 is the profile at A-A place in Fig. 1.
Fig. 3 is the left view of the static iron core of improvement described in the utility model.
