HRJB-Three-roller Mechanical Symmetrical Rolling Machine
HRJB-three-roller mechanical symmetrical rolling machine is mainly used for roll the steel plate into circular cylinder. The motor & reducer for rotation drives the two lower rollers to rotate through gears, the motor & reducer for lifting drives the upper roller to lift vertically at the symmetrical position of the center of the two lower rollers through the worm gear, worm, nut and screw, through the downward press of the upper roller and the rotation of the lower roller to achieve the purpose of rolling the steel plate. The equipment has the advantages of advanced structure, stable and reliable operation, high degree of automation, convenient operation and so on.
Extended Description
The rolling machine uses the movement of the upper and lower rollers to bend the steel plate into circular cylinder. The three-roller mechanical symmetrical rolling machine is currently the most widely used and most mature technology in the market. The structure of the three-roller mechanical symmetrical rolling machine is relatively simple and the function is single, but at the same time it has the advantages of convenient use and easy maintenance, and can fully meet the production needs of steel & FRP double-deck oil tank manufacturers for rolling cylinders.
The best-selling 8×2000 model has long-term inventory, and the other models generally have semi-finished products, which can be assembled with stock parts at any time, and the assembly cycle is 3-5 days.
