Product description:
Customized wedge type tension reel mandrel.
Application:
All expanding and collapsed mandrels we manufactured will be used for steel and other non-ferrous cold rolling mill and hot rolling mill and coil processing lines, such as pickling line, galvanizing line, color coating line, annealing line, cut to length line, slitting line, rewinding line, tension leveling line,etc.
wedge type tension reel mandrel, Ø610mm;
pyramid shaft, segments, hollow shaft, gripper segment, wedges, the materials of segments, pyramid shaft, gripper segment, hollow shaft, all high alloy steel forgings;
forging raw materials-----rough machining-----Ultrasonic Test-----quenching and tempering-----semi-finishing-----aging-----finishing machining-----nitriding treatment.
Through the hardness difference between segments and pyramid shaft to increase the wear resistance of the mandrel. The gripper hydraulic cylinder has high surface finish, and choose imported sealing ring to ensure extend mandrel service life.
Our company has perfect technological process for such structure,we also supply one stop service including design, manufacture, and mandrel assembly.
All expanding and collapsed mandrels we manufactured work for steel and other non-ferrous cold rolling mill and hot rolling mill and coil processing lines, like pickling line, galvanizing line, color coating line, annealing line, cut to length line, slitting line, rewinding line, tension leveling line,etc.
Our technical team could design and manufacture mandrels according to your specific application. Even you don’t have drawings, just tell us related parameters, we will meet and exceed your expectations.
