Motor stator steel belt pressing machine

Abstract

The invention relates to a motor stator steel belt pressing machine. The defects that existing stator iron cores are formed in a winding mode, inner circle edges of inner rings of the iron cores are liable to be compressed and thickened, stators are influenced, and finally the operation performance of motors is influenced are overcome. The machine comprises a base and a press arranged above the base. Through holes are formed in the center of the base and the center of the press. A fixing table is arranged in the through holes. An extendable supporting body is arranged on the fixing table. An extending rod is arranged above the fixing table. The outer side face of the supporting body is in an arc shape in the axial direction, and the outer side face of the supporting body is a cylindrical face after being extended by the extending rod. An iron core is placed into the space between the base and the press. The supporting body extends outwards under the action of the extending rod. The press moves downwards to press the iron core, pressing force is added, and an inner circle part of an inner ring of the iron core is extruded. Deformation caused by extrusion is limited by the supporting body, so that the size of an inner hole of the iron core after shaping is ensured, and the size precision of the upper surface and the lower surface of the iron core is also ensured at the same time.

Description

technical field [0001] The invention relates to the field of motor stator processing, in particular to a motor stator steel strip flattening machine. Background technique [0002] During the winding process, the steel strip of the stator core of the motor is wound on the plane where the steel strip is located, so that when the steel strip is wound, one side of the steel strip as the inner ring of the iron core acts as the inner circle of the winding. It is wound in a compressed way, and the other side is used as the outer circle of the winding. The thickness of the compressed side will increase after winding, which will have a certain impact on the shape of the iron core, so that the iron core is wound around the coil. After becoming a stator, there will be deviations, which will eventually affect the performance of the motor. [0003] Therefore, it is necessary to reshape the iron core after the stator iron core is formed to ensure the dimensional accuracy of the upper and...
