Roll grooving machine is an important tool in grooved piping connection system. The function of roll grooving machine is to make standard groove, while pipe walks off may happen during grooving process, why it is happens? It is usually related to whether the rollers are installed in place and the pipe supports are placed in place. In addition, the placement of roll grooving machine is not horizonal, the oil pump feeds too fast, and the pipe end is not flat, which may cause the pipe walks off.
As a professional roll grooving machine manufacturer, Victaulic-Tuwei recommends the following grooving operation step:
1.Check the workpiece: the pipe end should be flat without burrs, and the welded pipes inner should be smoothed.
2.Inspect the equipment: Check whether the power supply meets the requirements to prevent motor from damage. Check whether the hydraulic oil is sufficient, notice the machine will not work properly if there is not enough oil inside.
3.Place the pipe: Put one end of the pipe on the knurl wheel of the machine, and the other end on the pipe support, the pipe support should be placed at 2/3 of the total length of the pipe. then adjust the height of pipe support to horizontal or 1 degree lower.
4.Adjust groove depth: Tighten the relief valve, shake the oil pump handle, make the upper roller downward and touch the pipe surface. Then turn the limit nut down, let it contact the oil pump surface, check the groove depth on the nameplate , and rotate limit nut to the appropriate scale then fix it with fastening nut.
5.Grooving operation: Plug the power, start the roll grooving machine, and slowly shake the handle of the oil pump to start groove. When the limit nut contacts the oil pump surface, allow the pipe to rotate additional one or two turns to make sure groove is completed, then turn off the switch.
6.Measure groove depth: Release the relief valve, remove the pipe, and measure the groove depth with a PI ruler.
