Description
Technical field
The present invention relates to hybrid claw-pole alternator field, the sectional type cavity plate of especially a kind of mixed excitation claw-pole is whole
Shape dress is put and technique.
Background technology
In order to increase the generated energy of automobile current generator, hybrid claw-pole alternator is developed.As shown in Figure 9 and Figure 10,
This kind of hybrid claw-pole alternator is needed to place permanent magnetic iron block in the blade tooth side of pawl pole, and placement is set out forever in blade tooth side
The neck of magnet piece, neck have the first locating surface 21 and the second locating surface 22, the locating surface 22 of the first locating surface 21 and second
When being mutually perpendicular to be used to place permanent magnetic iron block, permanent magnetic iron block is positioned.But because blade tooth is complex-shaped, cause to pass through machining
Processing difficulties when shaping the neck of blade tooth side, waste time and energy.Pawl pole is generally shaped using the method for Plastic Forming at present, had
Shaped when body method is hot forging compared with Rouno Cormer Pregrinding Wheel and thicker neck, essence is then carried out to fillet and neck surface using cold shaping
It is whole, space of the unnecessary material without flowing during due to cold shaping, it has in hot forging in above-mentioned first locating surface 21 and the
The intersecting position of two locating surfaces 22 opens up capaciting material groove, capaciting material groove is filled by forward extrusion shaping afterwards, such a processing side
Formula influences the magnetic conductivity of workpiece.Simultaneously because lower cavity die die face forms upward power to blade tooth during forward extrusion shaping, blade tooth is recessed
Position in mould changes, the problems such as causing workpiece to deform.
The content of the invention
The purpose of invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of sectional type cavity plate of mixed excitation claw-pole
