LD240 Five-Roller Cold Pilger Mill
1. The main conveying system is with V belt which can make sure equal force , creditable and stable function .
2. There are airbag type clutch and hydraulic brake between belt pulley and driving shaft which can brake quickly and stop exactly during the urgency .
3. The precision of steel pipe is high enough to be manufactured thin-wall pipe with five-roller .
4. The rolling mill adopts edge feeding way removing the 脱芯棒 comparing to the side feeding . The exact location of mandrel on the deformation zone and short rolling line not only suit for rolling long tube billet but also improve the roller’s efficiency .
5. Electric-control feeding and discharging way improve the working efficiency .
6. It is easy to change and maintain the roller .
7.Twin-wire feeding way realize the stable feeding.
8. To tighten with hydraulic mandrel lowers the labor strength .
9. The mechanical CAM type rotary feeding way is stable and reliable .
