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.

Method for manufacturing laminated body

A method of manufacturing a metal product comprise forming a base region on a surface of a metal member by repeatedly scanning along a predetermined first direction while irradiating the surface of the metal member with a base laser beam over a first set of rows. The method further comprises forming a marking by repeatedly scanning along a predetermined second direction while irradiating the surface of the metal member with a marking laser beam over a second set of rows. The second direction is different from the first direction. An identification code having a predetermined pattern comprises a combination of the base region and the marking.

Method of manufacturing metal product and metal product

A manufacturing method of 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.

Manufacturing method of laminated iron core

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.

A method for manufacturing a laminated iron core product includes laminating a plurality of iron core members which are punched from a first metal plate to form a laminate, removing oil adhering to the laminate, removing oil adhering to an end surface plate which is punched from a second metal plate, and disposing the end surface plate on an end surface of the laminate and welding the end surface plate and the laminate.

Method for manufacturing laminated iron core product

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.

Manufacturing method of iron core product

A method of manufacturing a metal product includes forming a first identification code onto a surface of a metal member with a laser beam, the first identification code being readable under a first reading condition, and heating the metal member on which the identification code is formed. The method further includes reading the first identification code with a reading device, and forming a second identification code onto the surface of the metal member subsequent to the heating with a laser beam based on the first identification code which is read with the reading device. The second identification code is readable under a second reading condition different from the first reading condition.

Metal product manufacturing method

In the case of a laminated rotor core, insertion of permanent magnetsand filling of resininto each of magnet insertion holesare performed in order to cancel out a problem of an imbalanced weight estimated from a deviation of lamination thickness in a circumferential direction of a laminated core body, and a manufacturing method includes a step of measuring a deviation of lamination thickness in which an imbalanced weight is estimated by measuring the deviation of lamination thickness in the circumferential direction of the laminated core body, and a step of balance adjustment in which the insertion of the permanent magnetsinto each of the magnet insertion holesand the filling of resininto each of the magnet insertion holesare performed in a manner that cancels out a problem of this imbalanced weight.
