  • Patent number: 11258339
    Abstract: A manufacturing method of an iron core product includes: heating an iron core body attached to a jig together with the jig; removing the iron core body from the jig when the jig and the iron core body are heated to denote a first temperature; and separately cooling, after removing the iron core body from the jig, the iron core body and the jig such that the iron core body is at a second temperature lower than the first temperature and the jig is at a third temperature lower than the first temperature.

  • Publication number: 20210194336
    Abstract: A method for manufacturing a laminated body includes: laminating an electromagnetic steel plate to form the laminated body; performing an annealing process on the laminated body; acquiring a before-annealing lamination thickness information on a thickness of the laminated body before performing the annealing process on the laminated body; and when the before-annealing lamination thickness information does not satisfy a before-annealing criterion which is predetermined, adjusting a lamination condition of the electromagnetic steel plate such that the before-annealing lamination thickness information satisfies the before-annealing criterion.

  • Publication number: 20210143712
    Abstract: A manufacturing method of a laminated iron core by laminating a plurality of blanked members to form a laminate, the laminate including a pair of first and second end surfaces and the plurality of blanked members being interlocked by a caulk in a lamination direction of the laminate, includes: forming the laminate such that a protrusion of the caulk protrudes downward from the first end surface being in a downward state; placing the laminate on support such that the protrusion is not in contact with a support surface of the support; and processing the laminate in a state where the laminate is placed on the support.

  • Publication number: 20210067014
    Abstract: A manufacturing method of the a laminated iron core includes: laminating a plurality of punched members to form a temporary laminate; pressing the temporary laminate with a first load to obtain a laminate; and processing the laminate while pressing the laminate with a second load that is equal to or less than the first load. The manufacturing method of the laminated iron core according to the present disclosure provides a manufacturing method in which subsequent processing can be favorably performed after the laminate is obtained.
