  • BZS Parabolic Rolling Machine(roller driven by mechanical units)

This parabolic rolling machine is specially designed for light and medium leaf spring parabolic roiling as well as some kinds of heavy spring rolling. It has the advantage of lower investment cost, smaller motor capacity for lower working cost, easy to operate and easy to maintenance and etc. The PLC control makes the rolling without any die to roll different types of shapes. All what you do is just to enter a few parameters in the computer.. The Bosch hydraulic ratio servo valve is reliable and has fine anti-pollution functions. To meet different requirement of users, we offer semi Automatic or fully automatic line on option. The basic semi-Automatic line could just has a furnace and a rolling mill. The automatic device could add furnace loader, manipulator after rolling, straightening device, end cutting device, center hole punching device, cooling conveyer, stacking device and so on.
