W11xnc-80X3200center-Distance Adjustable Three-Roll Horizontal Downward Bending Machine

[The product can be customized. The actual customization prevails] The characteristics of the universal roller winding machine are as follows: The upper roll is shaped like a drum, and the lower part of the lower roll is adjusted with a roller, which can roll products with high straightness in a wide range from thin plate to thick plate. Unique rear winding process, continuous bending, avoid products "dead bend" and "sharp peach", can get high precision products. The prebending of the end of the plate adopts the direct pressure type of the upper roller, which can control the length and shape of the remaining straight edge and complete the high precision of the end prebending. Upper roller universal coiling machine adopts integral chassis, simple foundation, convenient mobile working place. Principal overviewThe machine belongs to the hydraulic three-roller plate bending machine, which is used to roll the steel plate into a cylindrical, circular arc androundingfunction; The upper roller can bemovedvertically; The pre-bending is achieved by the horizontal movement of the lower roller, and the lower roller is in an asymmetricalpositionrelative tothe upper roller; When rounding andcalibrating, the workingrolleris driven to provide the coiling torque for the coiled sheet; The elevation of the lower roller remains unchanged, which is convenient for feeding and operation; Main technical parametersserial numberName Unit Parameters 1Three roll plate bending machine type/Variable center distance lowerrollerleveladjustable2Rolled sheets yield to the limitMPa≤2453Maximum coil thicknessmm804Maximum pre-bent plate thicknessmm455Minimum roll diameter at full loadmmF20 006Maximum bin widthmm32007Remaining straight edge thicknessmm≤2.5times the thickness of the plate8Roll speedm/min49Upper roll diametermmF46010Lower roll diametermmΦ40011Two lower rollercenter distancesmm480-68012Work rollermaterial/42CrMo (temperedHB260-300).13The way the working rollermoves/Hydraulic cylinderdriven14Hydraulic system pressureMPa2015Hydraulic motor torqueKN.m1216Total installed powerKW5017Hydraulic cooling system/Oil cooler18Roller drive method/Hydraulic motor +planetary gear reducer19Lubrication system/It adopts automatic lubrication at start-up and timed forced lubrication20operating system/Two sets of operation systems: remote control and movable operating platformsystem, but mutually secure interlocking, only one system can be used at a time.

Upper roller device 1) Upper roller 2) Hydraulic motor 3) Reduction gear 4) Overturn bearing seat 5) Fixed bearing housing 6)Main oil Cylinder 7)Skateboard(Illustration of upper roller device).The upper roller device is mainly composed of upper roller, main oil cylinder, upper roller bearing seat, double row spherical rolling bearing, etc.The material of the upper working roller is 42CrMo, which has high strength and toughness, and is heat treatedHB260~300. The upper roller is preset with a drum shape with 50%uniform load, which improves the rigidity of the upper roller and greatly improves the straightness of the product. Two master cylinders provide the pressing force required to coil the plate, the cylinder block is 45 and the piston is 45steel forgings, the tempering treatment is HB215-255,and the main cylinder isYxseal. Double row spherical bearings are selected for low-speed, heavy-duty bearings.The lifting and lowering synchronization of the upper roller is controlled by PLC, and the synchronization accuracy is ±0Within 20mm. Both ends of the upper roller can be raised and lowered independently in order to realize the coiling of the cone. The main transmission device is composed of hydraulic motor+planetary reducer, whichdirectly drives the upper roller. The main drive can be reversed forward and reverse to power the coiling of the plates.A hydraulic motor that converts pressurized fluid energy into mechanical energy and then to the shaft via planetaryreduction gears.Hydraulic motor 2) cycloid reduction gear  3) coupling 4) stop gear 3-2.Lower roller and horizontalmoving device Lower roller 2, side hydraulic cylinder 3, bearing housing 4, slide plate 5, guide rail 7, horizontal guide 8.
