Problems solved by technology

However, the plastic skeleton of the straight stator core is prone to damage (with gaps), which leads to inconsistent heights of the straight stator core, and eventually leads to inclination, up and down misalignment of parts of the pressed iron core, and affects the verticality

Embodiment 1

[0064] Embodiment one, such as Figure 1 to Figure 26 As shown, a straight stator core forming mold for forming circles includes a frame 1 , a controller (not shown in the figure) flattening and shaping device 40 and a circle shaping mechanism 2 .

[0065] The circle-pressing and shaping mechanism 2 includes a plurality of circle-pressing and shaping assemblies 23, and the plurality of circle-pressing and shaping assemblies 23 are arranged on the shaping seat 20 at annular intervals, and are used to press the straight fixed iron core on the shaping seat 20 into a ring shape, and make the two ends of the straight stator core 5 lean against each other.

[0066] The flattening and shaping device 40 is arranged on the frame 1, and is used to press the straight stator iron core 5 up and down, so that the positions of the top of the straight stator iron core 5 on the same horizontal plane and the positions of the bottom on the same horizontal plane are kept flush. All positions rem...

Abstract

The invention relates to a rounding and shaping die for a straight-bar stator iron core, which comprises a rack, a jacking shaping mechanism, a pressing shaping mechanism and rounding shaping mechanism. According to the invention, a shaping center mold core is firstly sleeved with a straight stator core in advance; then a plurality of rounding shaping assemblies are used for jacking and pressing the straight-bar stator iron core in sequence; the plurality of rounding shaping assemblies are used for pressing the straight-bar stator iron core into a circular ring shape; the two ends of an opening of the straight-bar stator iron core abut against each other, so that the roundness of the straight-bar stator core is ensured; then the upper end surface and the lower end surface of the iron coreinner circle of the straight-bar stator iron core are jacked up and down through the jacking shaping mechanism and the pressing shaping mechanism; the jacking shaping mechanism and the pressing shaping mechanism are used for pressing and aligning all parts of the same horizontal plane of the top of the straight-bar stator core, the pressing shaping mechanism is used for pressing and aligning all parts of the same horizontal plane of the bottom of the straight-bar stator core; and finally, it is guaranteed that the roundness and perpendicularity of the welded stator core meet the requirements,and the product quality is qualified.

Description

technical field [0001] The invention relates to a circle forming die for a straight stator iron core designed for the straight iron core for a motor stator which is straight in an initial state and ring-shaped after forming. Background technique [0002] At present, most of the straight stator cores of motors are generally formed by winding. The shape of the straight stator cores is mostly circular before winding, but it is difficult to wind the wires on the circular straight stator cores. Large, long winding time, low slot full rate, large waste of copper wire, low production efficiency and other shortcomings. Therefore, part of the stator core adopts a strip-shaped straight stator core. The strip-shaped means that the straight stator core is strip-shaped before the winding is completed. The difficulty of winding wires on the strip-shaped straight stator core groove is reduced, and the production efficiency is high. After the winding is completed, the bar-shaped straight ...
