摘要： There are provided core part manufacturing method and apparatus for manufacturing a core part of a rotary electric machine. The core part manufacturing method includes: injecting a molten resin from a side on one end surface of an iron core body into a plurality of space portions provided in the iron core body in a state where the iron core body is sandwiched and pressed. In injecting of the resin, a contact surface on an opposite side to a side where the resin is injected includes: a relief portion that is recessed without contacting to the one end surface; and a remaining portion that is adjacent to a non-contact region. The remaining portion is disposed in the contact surface on an outer peripheral side from the non-contact region, and the relief portion is disposed further in the contact surface on an outer peripheral side from the remaining portion.

摘要： A laminated iron core manufacturing apparatus for laminating a plurality of punched members obtained by punching a plate-shaped member, including: a convey unit conveys the plate-shaped member; a lifter supports the plate-shaped member; a liquid material supply unit adheres a liquid material to regions to be the punched members of one main surface of the plate-shaped member; and a punching unit to punches the plate-shaped member after the liquid material is applied to form the punched members. The liquid material supply unit adheres the liquid material to the plate-shaped member while avoiding, in the regions to be the punched members in the plate-shaped member, a contact region where the lifter on a downstream side of an adhesion location of the liquid material in the liquid material supply unit and on an upstream side of the punching unit comes into contact with the plate-shaped member.

摘要： A laminated iron core includes a plurality of blanked iron core pieces laminated together, a continuity of side parts of the iron core pieces configuring a side surface of the laminated iron core. The side part of each iron core piece includes a specific light reflection area having a prescribed width along a circumferential direction, where the specific light reflection area has different light reflection characteristics from the other area of the side part of the iron core piece, and a striped pattern, configured by the specific light reflection areas, exists on the side surface of the laminated iron core.

摘要： 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.

摘要： A method of manufacturing a core product includes injecting molten resin into a resin injection portion provided in a core body so as to extend in a longitudinal direction of the core body, and forming a core product by welding the core body. A buffer region is set between the resin injection portion and a periphery of the core body in a lateral direction of the core body. The core product is formed by welding the core body so that a weld bead formed on the core body is prohibited from reaching the buffer region, and so that the weld bead is spaced apart from the resin injection portion in the lateral direction of the core body.

摘要： In a case where a permanent magnet is inserted into each of a plurality of magnet-insert holes of a laminated iron core and then a resin is injected into the plurality of magnet-insert holes from a resin pool pot formed in one of an upper die and a lower die with the laminated iron core pinched and the resin is cured inside the plurality of magnet-insert holes to fix the permanent magnets to the laminated iron core, a dummy plate which abuts on the laminated iron core and includes a gate hole for allowing passage of the resin delivered from the resin pool pot and guiding the resin to the plurality of magnet-insert holes. The gate hole partially overlaps with at least two of the plurality of magnet-insert holes in a plan view of the dummy plate and the laminated iron core.

摘要： A method of manufacturing a rotor includes mounting a plurality of core members to a shaft in a state by inserting the shaft into a shaft hole that penetrates through the plurality of core members in a height direction. An inner diameter of the shaft hole is larger than an outer diameter of the shaft. The method includes pressing the plurality of stacked core members together in the height direction to form a stack in which the plurality of core members are located adjacent to each other, and the shaft hole is engaged with the shaft.
