4 Roll Plate Roller (Plate Rolling Machine) is suitable for the bending forming work of sheet metal. It can roll round, curved and tapered workpieces within a certain range, and has the function of pre-bending at the end of the sheet. The remaining straight edges are small and the work efficiency is high. The metal sheet can be roughly leveled on the machine.

The 4 roll plate bending machine can bend the steel plate into a cylindrical surface, a conical surface or a cylinder of any shape or a part thereof is heated: the four-roll bending machine can curl the steel plate into a cylindrical shape or a part thereof, which can be used for some thicknesses Large, processed steel sheets that cannot be bent by conventional methods.

  • The material plate pre-bending only needs to be loaded once.
  • It can be bended up in many shapes, including round, curved, conical under certain conditions, etc., to obtain a larger tortuous curvature, and the yield is high. The principle of bending is: under less pressure, the plate is gradually attacked. Local deformation. Therefore, it is not easy to cause wrinkles and cracks when the data is in line. The required forming force is small, and therefore, the winding radius is small, and is suitable for forming difficult-to-deform data, such as titanium alloy, stainless steel, metal composite material, and the like.
  • The plate pre-bending straight plate is small, and the precision of the formed part is high. After the parts are bent, more precise curvature and higher edge parallelism can be obtained. The remaining straight edges at the end of the four-roller can be less than one times thick, which is beneficial to the porous sheet coated with the maintenance layer. Forming.
  • The material plate can be directly shaped and flat on the equipment, and the surface quality of the parts is good. Thanks to the maintenance of the elastic medium, the sheet with the maintenance layer and the polished surface can be tortuously formed without scratching the surface.
  • High production efficiency. Because the 4 roll plate roller is easy to operate and the running roller rotates fast, the labor productivity is greatly improved.
  • The outstanding advantage of the 4 roll plate bending & rolling machine is that it can pre-bend the end of the metal plate. During the processing, it can directly bend the end of the metal plate without relying on other equipment, eliminating the need for the end pre-bending process, and The lower straight edge is smaller, and no additional equipment such as a press is required for pre-bending, which has excellent process adaptability and high work efficiency, which not only improves the quality of the workpiece, but also has a simple process and convenient operation. This is a four-roller bending machine that is superior to a typical three-roller.
  • Hydraulic drive is adopted, which is less than mechanical transmission, low noise, high work efficiency, low energy consumption, compact structure and convenient maintenance.Suitable for heavy workpiece roll and high level of automation.
