The upper roller of the coiling machine acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder in the central symmetric position of the two lower rollers. The final gear of the main reducer drives the two lower roller gears to engage in rotary motion to provide torque for the rolled plate. . The three-roller is mechanical and hydraulic: the mechanical three-roller is divided into symmetrical and asymmetrical. The sheet metal can be rolled into a circular, curved and conical workpiece within a certain range.
The upper roller of the three-roller hydraulic symmetrical bending machine is vertically lifted and moved in the central symmetrical position of the two lower rollers, and is obtained by hydraulic oil in the hydraulic cylinder acting on the piston, which is hydraulically driven; the two lower rollers are rotated and passed through the reducer. The output gear meshes with the lower teeth to provide torque to the rolled sheet. The main feature of the three-roller hydraulic symmetrical bending machine is that the upper roller can be vertically lifted, the vertical lifting hydraulic drive is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven by rotation, and the lower roller has a roller at the lower part, and adjustable.
The three-roller hydraulic symmetrical bending machine is compact in structure and convenient in operation and maintenance. It is suitable for bending deformation of sheet metal. It can be rolled into round, curved and tapered workpieces within a certain range, and has a pre-bending function at the end of the sheet. The friction part of the three-roller bending machine needs to be lubricated, and should be refueled regularly to keep the parts running normally. The exposed parts of the open gear and the worm gear and the worm are lubricated with butter (butter).
