Background

The stator core is an important component of the magnetic circuit of the motor, and the stator core, the rotor core and the air gap between the stator and the rotor form a complete magnetic circuit of the motor. The stator core is an important part of the stator and is also a main component of a magnetic circuit of the motor. The stator iron core is formed by punching a silicon steel sheet into a fan-shaped sheet and overlapping the fan-shaped sheet on the positioning rib, welding the positioning rib on a base ring plate through a supporting plate, and pressing the iron core into a whole through the upper tooth pressing plate and the lower tooth pressing plate by using the tensioning bolt, and the iron core is also a part for placing a winding, and is subjected to the comprehensive action of mechanical force, thermal stress and electromagnetic force when a generator runs.

The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, the development level of die production is one of important marks of the mechanical manufacturing level, and in the working process of the die, because a male die and a female die are separated and combined at high frequency, the male die and the female die can deviate from the original positions due to vibration and the like, and the collision between the male die and the female die during die assembly can cause the damage of the die, so the alignment between the male die and the female die during working is of great importance.
