摘要

PROBLEM TO BE SOLVED: To reduce personnel expenses and costs and shorten due date of delivery by performing tapping machining as well as press machining in a progressive press machining process. ;SOLUTION: A drive shaft 6 and a machining shaft provided elastically by a plunger are provided in a main body 1 (1a to 1d) so as to turn freely, and gears 2, 3, 4, 5 are meshed and provided together. A screw tap 9 protrudes on a machining shaft 7a on a top face of the main body and is fixed thereon, and a ball female screw body screw-fitted in a ball screw 7d which comes into contact with a machining shaft 7b on a lower face of the main body 1d continuously and protrudes is fixed on the lower face of the main body 1d. A drive shaft joint part 6a which is provided on the lower face and protrudes and a servo motor which is driven in the interlocking relationship with a press molding machine are connected mutually, and the screw tap 9 is rotated forward and reversely by a proper amount due to the drive of the servo motor during one stroke of the press molding machine.;COPYRIGHT: (C)2000,JPO
