Abstract
To provide a ring cutting device capable of appropriately cutting a ring member.SOLUTION: The ring cutting device 1 cuts an O-ring 70, and includes a holder 11, a magazine 12, a cutting plate 53, a cutting cylinder 45, and a weight 15. The holder 11 is provided on the outer peripheral side of the O-rings 70 in the stacked state. The magazine 12 is inserted into the inner peripheral side of the stacked O-rings 70. The cutting plate 53 is provided so as to be slidable on the lower side in the vertical direction of the holder 11 and the magazine 12, and cuts a predetermined number of O-rings 70 to the outside of the holder 11. The cutting cylinder 45 drives the cutting plate 53. The weight 15 is placed on the upper side in the vertical direction of the stacked ring members.SELECTED DRAWING: Figure 4
