Two-roller cold pilger mill is unique-designed, which process with kinds of tube and pipe such as carbon steel, alloy steel, alloy steel stainless steel, non-ferrous steel, rare metal etc. And it can lower the wall value , sizing massively and stay in long working time. The mill features big 〇D and WT reduction, long working distance, which made the mill more efficiency, The products are widely used in the fields of metallurqy、automobile bear making petroleam machinery etc.
Its features as following :
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 adoption of ring groove roller is to realize long term rolling . Big rotation angle of roller , longer ring type working stage and increased length of deformation zone lead to the uniformity of metal deformation during the rolling . At the same time , it can increase feeding volume and improve the quality of the final processed pipe .
4.The rolling mill adopts edge feeding way removing the mandrel 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 easier to replace the roller and more convenient to maintain based on the open rack .
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.
