The two roll rounding machine, also known as the two roll rounding machine, consists of a rigid upper roll and a flexible lower roll. It is driven by an electric motor through a reducer and a coupling, and is vertically raised and lowered by a hydraulic unit. It is fixedly installed on the machine bed. When the lower roll contacts the upper roll, the lower roll will have a certain radial concave shape under the pressure of the upper roll. When the steel plate is fed between them, it will be rolled into a cylinder by the two rolls. From a microscopic perspective, the steel plate rolled into a cylinder is composed of countless small arcs. This is a two roll coiling machine.

The hydraulic automatic two roll rounding machine adopts PLC automatic control mode and hydraulic propulsion two roll forming technology. With a reliable and stable mechanical structure, it can roll carbon steel and stainless steel products with a thickness of 0.3-10mm. The operation is simple, the quality of the rolled products is stable, and the efficiency is high. It is widely used in automotive parts, solar water heaters, storage tanks, etc. The equipment can be customized and mass-produced according to different product requirements.
