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

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.
