Background
The motor stator and rotor iron core comprises a motor stator iron core and a motor rotor iron core which are all formed by laminating silicon steel sheets (punching sheets). The silicon steel sheet is usually formed by punching a punch press using a progressive die. Generally, an upper template, a lower template and a discharging plate positioned between the upper template and the lower template are arranged on a stamping progressive die, a plurality of male dies are arranged on the upper template, female dies matched with the male dies are arranged at corresponding positions of the lower template, so that a plurality of blanking stations are formed, during stamping, a material belt moves forwards in a stepping mode from the upper template to the lower template, through holes, tooth sockets and inner contours on motor stator core punching sheets are stamped through stamping dies (male dies and female dies) on all stations in sequence, and finally the core punching sheets are stamped from the material belt through the blanking male dies and the blanking female dies on the blanking stations. In order to realize the automatic stacking of the iron core punching sheets, an automatic stacking mold is arranged below a blanking female mold of a stamping progressive mold, main elements of the automatic stacking mold are tightening rings which are used for containing the iron core punching sheets and are in interference fit with the iron core punching sheets, the iron core punching sheets which are blanked are extruded one by one into the tightening rings under the action of downward stamping force of a blanking male mold during blanking, and therefore a stacking structure of the iron core punching sheets is formed in the tightening rings.
In the prior art, the fixing mode of the laminated structure of the iron core stamped sheet is commonly the riveting fixing and the welding fixing. The iron core punching sheets in the overlapped riveting fixing mode are stamped with overlapped riveting points, and when the iron core punching sheets are stacked, the adjacent two iron core punching sheets are combined with each other through the overlapped riveting points on the adjacent iron core punching sheets. The iron core punching sheets adopting the welding fixing mode are free of overlapped riveting points, and when the iron core punching sheets are overlapped, the adjacent two motor stator iron core punching sheets are combined together through welding.
Due to the existence of the overlapped riveting points and the reason of the manufacturing process, a certain gap may exist between two adjacent stamped sheets of the motor stator iron core after the overlapped riveting, so that the magnetic performance of the iron core is influenced. The iron core punching sheet of the welding and fixing mode saves the overlapped riveting point, the gap between two adjacent punching sheets is reduced, but the iron core magnetic circuit is influenced by the inward fusion welding during the iron core welding, so that the electromagnetic performance of the iron core is influenced, the efficiency of the produced motor is reduced, and the energy consumption of the motor is increased.
