Experienced users know that it has sliping problem sometimes when 4-roll plate bending machine is working. This situation occurs due to too low pressure. With its rich experience, STARS Machinery found two solutions to this problem during the research and development process.
Material Clamping of 4-roll Plate Bending Machine
The Stars Machinery 4-roll plate bending machine reliably improve and strengthen the clamping. In other words, when machine clamps the plate tighter during the pre-bending process, completely avoiding slippage.
Dual drive power
Stars Machinery makes the 4-roll plate bending machine with double driving power. The double-roller drive ensures more stable and reliable clamping, and the edge of the sheet can be closer to the clamping point.
The edge of the board is closer to the clamping point, which is the best position to get the shortest straight edge length.
After the pre-bending is completed, the moving plate needs to be continued to be rolled. The upper and lower rollers are fully driven, clamping and feeding from both sides of the plate. And the clamping and feeding force is distributed on both sides of the plate. As a result that ensure more precise feeding control.
Morover, when rolling thin plates and narrow plates, the synchronous movement of the upper and lower rollers can ensure reliable and stable feeding.
Each independently driven roller is directly connected with a hydraulic motor to ensure stable and reliable sheet feeding. The direct connection method is a standard feature of the drawing equipment, and the torque can be sent directly to the plate, avoiding power loss.
For plate rolling machines from other manufacturers on the market, the driving roller is only the upper roller. When producing thin plates or narrow plates, the pressure of the lower roller relative to the upper roller will usually cause slipping when it is too low, and the material will deform when it is too high, etc. The problem. Furthermore, their equipment usually adopts the structure of gearbox or friction wheel, which has low transmission efficiency and huge energy consumption loss and waste.
