Cold Pilger Mills For Tube Rolling Of Plates
Cold pilgering process is a complex tube making process in which both diameter and thickness of the tube wall are reduced. It is generally chosen for its dimensional accuracy controlled by ratio of diameter to thickness reduction. In pilgering process, the profile of the roller die and mandrel is very important because the outer diameter surface finish depends on the roller die profile and inside diameter surface depends on the mandrel profile. Generally linear tapered profile is used for the mandrel. This paper focuses on optimum shape of Pilger mill mandrel, using FEM software considering different materials. The profile of the mandrel surface was analyzed with linear and parabolic shape using AISI H11 and AISI M4 tool steel material considering the fatigue loadingl. At the end of the analysis, the result shows that the model of the parabolic profile with M4 material gives the better result than linear with M4 material as well as both the profile of H11 material.

Cold Pilger Mill Brief Introduction:
Our cold pilger mills use a special cold forming process which is both cost-efficient and indispensable for many applications. It involves a large number of forming steps to improve roundness, stress homogeneity, and surface roughness of the tubes. You can even apply our cold pilger mills to produce difficult materials beyond the capabilities of other processes.Our cold pilger mills use a special cold forming process which is both cost-efficient and indispensable for many applications.

Cold Pilger Mill Features
Equipment advantages:
1) Low maintenance cost
2) Easy operation
3) Extremely high yield
4) Low failure rate
5) Product with high precision
Cold Pilger Mill Equipment working principle:
Prefabricate the tool and die of the size required, and then install the tool and die within the equipment. In the working process of the equipment, the billets will be fed forward successively, in which the upper and lower roller will move in a reciprocating way, the outer diameter and wall thickness of the billet will be re-rolled to realize the size required by the customer through the physical change.
