Abstract
PURPOSE: To obtain an equipment for manufacturing grooved metallic pipes which can efficiently perform grooving works, by constituting the equipment in such a way that the advance and retreat of the tooth form roll toward and from the mandrel before the grooving work is started are performed by driving a slide block.
CONSTITUTION: An oscillating arm 50 is oscillated counterclockwise by driving 66 a tooth-form roll advancing-retreating mechanism 38, and a tooth-form roll 20 is retreated from a mandrel 12. Then, a metallic pipe 1, on which the grooving work is to be performed, is fitted to the mandrel 12 through a hollow shaft 28. After that, the mechanism 38 is driven 66, and the three rolls 20 are engaged with the mandrel 12 with the pipe 1 in-between by oscillating the arm 50 clockwise. In this case it is necessary to take care so that a tooth 20a of the roll 20 may be fitted to a groove 12a of the mandrel. Then, a rotating means 22 is driven 30, and the grooving work is performed in the direction of the length on the whole periphery of the pipe 1 while the pipe 1 is pulled rightward with an appropriate means.
