Title:
PIPE GROOVING DEVICE
Document Type and Number:
Japanese Patent JP2021181122
Kind Code:
A
Abstract:
To provide a pipe grooving device.SOLUTION: A device for forming circumferential grooves in pipe elements uses multiple geared cam bodies mounted on a carriage which rotates about a fixed pinion. The gears engage with the pinion which causes the geared cam bodies to rotate relative to the carriage. Traction surfaces and cam surfaces on the cam bodies traverse the outer surface of the pipe element and impress a circumferential groove therein. To substantially prevent rotation of the pipe element, the pitch circle diameter of the pinion equals the outer diameter of the pipe element, and the pitch circle diameters of the traction surfaces equal the pitch circle diameters of the gears.SELECTED DRAWING: Figure 1
