Three-roll plate winder Performance characteristics: the structure of the machine is three-roll symmetrical, the upper roll in the symmetrical position of the two lower rolls for vertical lifting movement, through the screw worm drive, the two lower rolls for rotary movement, driven by the motor. The output gear of the reducer meshes with the gear of the lower roll to provide torque for the rolling sheet. The main characteristics of asymmetric machine: the structure of the machine is three-roller asymmetric type, the upper roller is the main drive, the lower roller vertical lifting movement, and through the lower roller gear and the upper roller gear meshing, as the main drive; The side roller has double functions of pre-bending and rolling. Compact structure, easy operation and maintenance.
Hydraulic three-roller plate rolling machine: this machine is a symmetrical three-roller plate rolling machine, which can roll metal sheet into round, arc and conical workpieces. The two lower rollers are active rollers, and the upper rollers are driven rollers. Widely used in shipbuilding, boiler, hydropower, chemical, metal structure and machinery manufacturing industries. This machine is suitable for bending deformation of metal sheet, can roll round, arc and conical workpiece in a certain range, with the prebending function of plate end, this model two lower roller for the active roller can move horizontally, the upper roller for the driven roller can move up and down, the drive shaft are connected by universal coupling.
Working principle: the upper roller of the bending machine acts on the piston in the symmetrical position of the two lower rollers through the hydraulic oil in the hydraulic cylinder for vertical lifting movement, and the final gear of the main reducer drives the gear of the two lower rollers to rotate cooperatively, providing torque for the rolling plate. Rolling machine specifications flat plastic metal plate through rolling machine three work roller (two under the roller, a roller) between, with the help of the roller pressure and rotation of the roller, so that the metal plate through multiple times of continuous bending, plastic deformation, roll into the required cylinder, cone or part of them. The disadvantage of the hydraulic three-roller plate winder is that the plate end needs to be prebent by other equipment. The plate rolling machine is suitable for large plate rolling machine whose thickness is more than 50mm. The lower part of the two rolls increases a row of fixed rollers to shorten the span of the two rolls, so as to improve the precision of the rolling workpiece and the overall performance of the machine. Types: three roller bending machine mechanical and hydraulic: mechanical three roller bending machine is divided into symmetric and asymmetric.
Mechanical three rollers symmetrical type machine, three rollers symmetrical type mechanical lapping machine characteristics: this machine structure is three rollers symmetrical type, roll on the roll under two symmetrical position for vertical lifting movement, obtained through the screw silk worm drive, the two bottom rollers for rotation, through the output of the speed reducer gear and roller gear mesh, torque for rolling plate. The disadvantage of this machine is that the plate end needs to be prebent by other equipment.
Main features: the structure of the machine is three-roller asymmetric type, the upper roller mainly drive, the lower roller vertical lifting movement, to clamp the plate, and through the lower roller gear and the upper roller gear meshing, at the same time as the main drive; The side roller has double functions of pre - bending and rolling. Compact structure, easy operation and maintenance. Technical parameters: Specifications model coil * thickness.
Hydraulic three-roll plate rolling machine: hydraulic three-roll symmetrical plate rolling machine main features: the machine roller can be vertical lifting, vertical lifting hydraulic transmission, through the hydraulic oil in the hydraulic cylinder piston rod and obtained; The lower roller is driven by rotation. The lower roller is provided with an idler and can be adjusted. This machine is a symmetrical three-roller plate rolling machine of up-regulating type, which can roll metal sheet into round, arc and conical workpiece within a certain range. The two lower rollers of this machine are active rollers, and the upper rollers are driven rollers. It is widely used in shipbuilding, boiler, hydropower, chemical, metal structure and machinery manufacturing industries. This machine suitable for sheet metal bending deformation, rolling round, arc and a range of conical workpiece, and a plank end bending function, the model of the roller under the conditions of the two active roll can move horizontally, the roller is driven roller can move up and down, move way are mechanical and hydraulic, transmission shaft are connected adopt universal shaft connection.
