Abstract:
PROBLEM TO BE SOLVED: To provide a burring device capable of easily replacing a bit.SOLUTION: A burring device 100 positions a bit 90 placed on a bit rest 62 in a position of a prepared hole 3 in a metal pipe 1. A bit gripper 52 holds the bit 90 via the prepared hole 3, and forms a burring part 5 by lifting this. Burring processing of a different diameter can be executed by replacing the bit 90 placed on the bit rest 62 to the metal pipe of the same diameter. Thus, the burring processing to the metal pipe 1 can be efficiently executed in a further shorter time.SELECTED DRAWING: Figure 1
