Title:
A rotation child's manufacturing method
Document Type and Number:
Japanese Patent JP6059024
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a rotor which effectively uses the remaining heat at the time of resin sealing, and does not reheat a laminated iron core in which a permanent magnet is sealed with resin even when trouble occurs in a line.SOLUTION: A method of manufacturing a rotor includes: a preheating process 18 of heating a laminated iron core 14 in which a permanent magnet 15 is inserted to each magnet insertion hole 13; a resin sealing process 27 of fixing the permanent magnet 15 to the magnet insertion hole 13 by injecting resin to the magnet insertion hole 13 from a resin sump pot 24 provided on an upper die 19 or a lower die 20 in the state in which the laminated iron core 14 is held between the upper die 19 and the lower die 20; a heat retaining process 28 of retaining heat with a heat retention device without cooling the laminated iron core 14 having passed through the resin sealing process 27; and a shaft assembling process 30 of performing warm-fitting processing in which a shaft is fitted to a shaft hole 12 of the laminated iron core 14 which is taken out from the heat retention device and in the heated state, or in the heat retention device.
