How using low cost, producing high-quality product is the constant theme of product technology innovation.The product of how to utilize Limited resources, producing greater number is that manufacturing industry need be thought deeply and the problem that solves.Improve product competitiveness, promote product profit, become the theme of employee, enterprise and national invariability.
As shown in Figure 1, existing shaping stator iron core method is directly processed existing U type stator core 1 ' through modes such as overshoot, rivetings for making silicon steel sheet or cold-reduced sheet strip in high velocity ram machine.This traditional molding mode causes silicon steel sheet or cold-reduced sheet material utilance low, is approximately 62%, this means that 38% material will be scrapped processing.
The utility model content
The purpose of the utility model is to solve U type stator core in the processing and manufacturing process, and the problem that the raw material scrap rate is high provides a kind of technical scheme that promotes stator core utilization rate of raw materials in the course of processing.
In order to reach the foregoing invention purpose; The utility model has adopted following technical scheme: bending type U type stator core; Said U type stator core is bent to form by a strip main body; Said strip main body comprises the 3rd main body in the middle of being positioned at and is positioned at first main body and second main body of the 3rd main body both sides; Said strip main body is with respect to the center line left-right symmetric of the 3rd main body, first main body of said the 3rd main body and its both sides and second main body have that the bottom links to each other and top to directly over be 90 spend openings connecting portion.
Said connecting portion is provided with the bending groove in open bottom, with the operation moulding of convenient back.
The upper surface of said first main body and second main body is respectively equipped with interior concave arc, when being bent into U type stator core, said in concave arc symmetrically and be formed for holding half enclosed space of rotor.
It is silicon steel sheet or cold-reduced sheet strip that said strip main body adopts material.
A kind of U type AC magnetoelectric machine comprises p-m rotor and stator, and said stator adopts aforesaid bending type U type stator core.
A kind of U type AC permanent-magnet water pump comprises pump cover, the pump housing, fan blade, p-m rotor and stator, and said stator adopts aforesaid bending type U type stator core.
The utility model is that silicon steel sheet or cold-reduced sheet strip are become strip through overshoot, riveting in high velocity ram machine, and does not directly become the U type, uses frock or equipment assistant formation U type then.Through the mode of the utility model, stock utilization can reach 80%, effectively promotes stock utilization.Through after the punching press, the strip main body is reserved with crooked place, and the silicon steel sheet tailing still links together, and plays fastening effect after the moulding, avoids loosening and the crack is arranged and produces noise excitation is exerted an influence.
