The present invention also provides a kind of manufacturing methods of takeup type small-rabbet chute stator iron core, comprising the following steps:
Step 1 carries out punching press to steel band, forms stator material strip；
Step 2, by stator material strip winding to the winding material strip of stator core thickness half；
Step 3, by the mutual reverse-winding of winding material strip as two, form the chute stator iron core of certain angle；
Step 4, welding, form finished product.
The present invention also provides the manufacturing method of another takeup type small-rabbet chute stator iron core, method includes following step
It is rapid:
Step 1 carries out punching press to steel band, forms the opposite stator material strip of two rooted tooth shapes；
Two stator material strips are superimposed by step 2；
Step 3, two stator material strips carry out coiling process simultaneously and form winding material strip, cut after reaching required thickness；
Step 4 carries out skewed slot rotation by welding tooling and welds, and forms finished product.
Further, the step 2 further includes being mutually aligned the tooth of the stator material strip, and the tooth is superimposed to be formed
Symmetric teeth.
Further, the tooth form of stator material strip described in the step 1 is L shape or T shape.
In better embodiment of the invention, the maximum solid of helical teeth tooth head is made to become larger, so that the chute stator
The skew notch size of iron core becomes smaller, and stock utilization is high.
In another better embodiment of the invention, maximum solid is increased so that notch becomes smaller, and mentions after the superposition of tooth head
High stock utilization.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
