Patent number: 10843249Abstract: A machining apparatus includes a movement direction converting mechanism that converts lowering movement of a first punch into raising movement of a second punch and converts lowering movement of the second punch into raising movement of the first punch. The first punch and the second punch are raised and lowered in an alternating manner by this movement direction converting mechanism. Accordingly, machining by the first punch and machining by the second punch are performed individually.Type: GrantFiled: September 26, 2018Date of Patent: November 24, 2020Assignee: HONDA MOTOR CO., LTD.Inventors: Keiichiro Oka, Takayuki Motojima, Yosuke Komatsu, Yasuhiro Kinoshita
