The four-roller bending machine and the three-roller bending machine have different forms of roller movement, but the working principle is the same. They all use the principle of three-point circle to roll different radii.
The four-roller bending machine and the three-roller bending machine have different forms of roller movement, but the working principle is the same. They all use the principle of three-point circle to roll different radii. The position of the upper roller is fixed, and the lower roller moves upward and linearly to clamp the steel plate. The two sides of the roller linear or arc move closer to the upper roller to adjust the radius of curvature of the reel. In the summer high temperature season, if the four roller bending machine is used for a long time, it will generate a lot of mechanical heat. If the temperature is too high, it is likely to cause damage. The cause of the four-roller plate bending machine heating: the pressure adjustment is too high, so that the speed of the plate bending machine becomes faster, thus burning out the sealing ring and the side plate.
Before starting the machine, please check the power system of the coiler to see if the operation of the mechanical system is safe and reliable. Add smooth oil according to the requirements of the smooth chart. The oil tank of the plate bending machine is too small, which makes the heat dissipation condition poor. Because the axial clearance is too large or the sealing ring is damaged and then leads to internal leakage. After turning on the power, check the rotation direction of the large gear. After confirming that it is normal, turn on the foot switch. All the rolled plates of the plate bending machine manufacturer must be placed in the center of the roller shaft for rolling. No slippage is allowed during the rolling process.
Maintenance and repair of the machine can only be carried out during parking. After the operation of the CNC four-roller plate bending machine is completed, the power supply should be blocked, the machine bed should be cleaned, the guide rail should be cleaned, and the blade should be filled with an appropriate amount of smooth oil. After the equipment is found to be faulty, it should be stopped in time and the maintenance personnel should be contacted. The four-roller bending machine is suitable for bending and forming metal plates. It can roll round, arc and tapered workpieces within a certain range, and has the function of pre-bending the end of the plate. The remaining straight edge is small, the work efficiency is high, and the metal plate can be roughly leveled on the machine.
