Document Type and Number:
Japanese Patent JP2021024039
Kind Code:
A
Abstract:
To provide pipe end face chamfering equipment which can surely crush cutting chip generated by cutting of a pipe end face, with a crusher without causing clogging of the chip.SOLUTION: A crusher 50 is provided below a pipe end face. The crusher 50 includes a pair of rotational shafts 54a, 54b arranged in parallel with each other. Disc-like crushing blades 55 which rotate with the rotation of the rotational shafts are attached to the rotational shafts. The rotational shafts and the crushing blades are arranged in a receiving port 51a of the crusher in the plan view. The crushing blades are disposed in such a manner that the crushing blade attached to one rotational shaft and the crushing blade attached to the other rotational shaft are partially overlapped with each other in the shaft direction of the rotational shaft and the opposite side surfaces of the adjacent crushing blades in the shaft direction are substantially in contact with each other. The pair of rotational shafts rotate toward the center between the rotary shafts in the plan view, thereby drawing and crushing cutting chip with the crushing blades and discharging the cutting chip to the lower side of the crusher.SELECTED DRAWING: Figure 4
