Motor stator steel belt feeding mechanism

Abstract

The present invention relates to a motor stator steel band feed mechanism. The defect is solved that a current steel sheet needs to weld to complete iron core processing after reeling to cause welding stress residual and iron core deformation. The motor stator steel band feed mechanism comprises a steel band feed machine; a steel band punch is provided with a lower die and a punch, wherein the lower die is provided with a support plane; a groove is arranged at the position, corresponding to the iron core rivet, on the support plane; and the punch includes two parts, one part corresponds to the compaction punch of the planar position of the support plane, the other part is a rivet punch located in the interior of the compaction punch and capable of telescoping relative to the compaction punch, and shear blades are arranged around the compaction punch. The groove matches the punch, the punch is able to pass through the rivet portions in the process of steel band linear processing, and when the steel band is overlapped after spiral curling, the rivet portions are mutually riveted so as to save the welding operation, reduce the welding stress and avoid the iron core deformation.

Description

technical field [0001] The invention relates to the field of motor stator processing, in particular to a motor stator steel belt feeding mechanism. Background technique [0002] The stator core of the motor is made of stacked steel sheets. Before the steel sheets are stacked, the steel sheets must be formed. The general forming process is mostly carried out by winding. The linear steel sheet is rolled by a winding machine. The loose iron core is wound in a circular shape with a predetermined number of turns, and then separated from the toothed material belt by a shearing device, and the formed loose iron core is welded so that the corresponding teeth are neat and the size is within the specified range integral stator core. However, the way of welding is easy to leave welding stress at the welding position, so that the stator will be deformed under stress. [0003] The coiled iron core has two ends, and the two ends will become abrupt positions of the stator, so the positio...

AI Technical Summary

Problems solved by technology

[0004] The invention solves the defects that the iron core needs to be welded to complete the iron core processing after the steel sheet is wound, resulting in residual welding stress and deformation of the iron core, and provides a motor stator steel strip feeding mechanism, which is straight when the steel strip is stamped When the structure is formed, the protruding riveting parts are punched out on the steel strip, and the steel strip is directly flattened after winding, and the riveting parts are interlocked to form riveting joints, no welding is required, and welding stress is eliminated

[0005] The present invention also solves the defect that two ends are formed in the existing steel strip winding and forming, and the ends need to be flattened, but the treatment effect is poor. It provides a motor stator steel strip feeding mechanism. After the strip is coiled and formed, the position corresponding to the end of the steel strip is pressed into a bent shape by a flattening machine, so that the surface of the iron core is even and the end treatment effect is good
