Embodiment Construction

[0040] Below by embodiment, in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0041] A kind of processing technology of the stator iron core of winding type motor, comprises the following steps,

[0042] (A) Uncoiling and leveling the disc-shaped steel strip;

[0043] (B) Stamping: adopt press machine to stamp steel band into linear strip with continuous teeth by stamping die;

[0044] (C) Winding: Feed the linear toothed strip into the winding mechanism, wind it into a circular and spiral loose iron core with a predetermined number of turns, and then pass the strip cutting mechanism from the toothed strip separated from

[0045] (D) Welding: Weld the formed loose iron core on a welding machine to form an integral stator iron core with neat corresponding teeth and a size within the specified range;

[0046] (E) Shaping: put the welded stator core into the shaping mold for pressure shaping;

[0047] (F) San...

Abstract

The invention discloses a process for processing a stator iron core of a winding type motor. The process comprises the steps of disc-shaped steel band uncoiling and leveling, stamping, winding, welding, reshaping, sand blowing and electrophoresis, wherein an automatic winding and shearing machine integrated with a winding mechanism and a shearing mechanism is adopted in the winding step, the smooth band feeding is ensured, the feeding speed is high, stamping stress of bands can be also eliminated, and the winding accuracy is improved. Furthermore, a newly-designed welding machine is adopted in the welding step, and the surface quality of welded products is improved.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a processing technology for a winding motor stator core. Background technique [0002] At present, the relatively advanced manufacturing process of the winding motor stator core usually includes the following steps: (1) Uncoiling and leveling the disc-shaped steel strip; (2) Stamping: using a press to pass through a progressive stamping die Stamping the steel strip into a straight strip with continuous teeth; (3) Winding: The straight toothed strip is directly connected to the feeding device of the winding machine through the guide frame and the stagnation chute, and the winding The loose iron core is wound into a circular shape with a predetermined number of turns on the machine, and then separated from the toothed material belt by a shearing device; (4) Welding: The formed loose iron core is welded into corresponding teeth. Integral stator core that is neat and within the spec...
