Problems solved by technology

Since most of the motor stator cores assembled in blocks use flying fork winding machines to wind the coils, the slots are formed by splicing two adjacent stator tooth blocks, so there is no problem of wire nozzles passing through the stator slots, and The slot width of the stator is made as narrow as possible or even a closed slot, which eliminates the above problems, but there are also: the structure is not tightly matched, it is easy to leak magnetic flux, the splicing magnetic circuit between the blocks is disconnected, and the iron loss will increase. The assembly process is complicated, the welding process is cumbersome, and special tooling is required for assembly. When assembling, the blocks are easily misaligned, the top and bottom are inconsistent, there are many thread ends, the production efficiency is low, and the motor energy consumption is high.

Abstract

The invention relates to a slit punching sheet overlying and forming die suitable for hinge type stators. The slit punching sheet overlying and forming die is a progressive die and comprises an upper die base and a lower die base. The upper die base comprises a left punching male die assembly, a right punching male die assembly, an overlying and riveting male die assembly and an appearance blanking male die. The lower die base comprises a left punching female die assembly corresponding to the left punching male die assembly, a right punching female die assembly corresponding to the right punching male die assembly, an overlying and riveting female die assembly corresponding to the overlying and riveting male die assembly, and an appearance blanking female die corresponding to the appearance blanking male die. By means of the slit punching sheet overlying and forming die, the hinge type stators are assembled into a finished hinge type stator from scattered fan-shaped punching sheets, and the slit punching sheet overlying and forming die has the advantages of being high in production efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to the technical field of motor stator manufacturing. Background technique [0002] The existing motor stator iron core is formed by stacking punched sheets. The punching sheet is a one-piece ring structure. The inner winding machine is used to wind the wire on the stator core installed with insulating medium. The nozzle of the inner winding machine can only be wound through the slot on the stator core. Therefore, the width of the slot must be greater than the width of the nozzle, that is, the notch must be wider. However, the wide slot of the stator of the motor will cause the rotor of the permanent magnet motor to generate a huge cogging torque when it rotates, which restricts the application of the motor in the field of high-precision control. At the same time, when the wire nozzle reciprocates in the winding process, there will be skeletons, and the wire nozzle is easy to b...
