Abstract
PURPOSE: To obtain a rectangular core of good magnetic characteristic in the method of simple work, by such manner that, with a silicon steel belt cut into pieces of different length in a manner of considering the core space factor, after a completion of forming said steel belt into a circular core in the layer-built processing, a core metal be press-inserted to press the periphery.
CONSTITUTION: After cutting a silicon steel belt 1a of coil-shape by a cutting machine 3 into pieced of different length in a manner with the core space factor considered, the forming is made by a rubber roll 5 and a steel roll 6 into a silicon steel belt ring 1c of circular shape. Then with several sheets processed a layer- built into one group while shifting their seamed positions, those of the groups A to D are overlapped, with the outermost periphery tightened by a steel band 8, and processed a non-return lock. Further with a press forming core metal inserted into the inside of the above core, by pushing and expanding said metal core with an oil hydraulic press used, the forming is to be processed into a rectangular core. Consequently, a rolled core of good magnetic characteristic can be obtained by a simple work as well as the man-power required can be saved.
