Rolling machine due to the use of different areas, the type is also different. From the number of rollers are divided into three-roller plate bending machine and four-roller plate bending machine. The three rollers are divided into symmetrical three-roller plate bending machine, horizontal downward adjustment three-roller plate bending machine, arc downward adjustment plate bending machine, upper roller universal three-roller plate bending machine and hydraulic numerical control plate bending machine. From the transmission on the mechanical and hydraulic.
From the development of the bending machine, the upper roller universal type is backward, the level down adjustment type is slightly advanced, and the arc down adjustment type is advanced.
Three roller bending machine has 1, mechanical and 2, hydraulic
1. The mechanical three-roller bending machine is divided into symmetrical and asymmetrical.
mechanical three-roll symmetrical type
Performance characteristics of mechanical three-roller symmetrical plate bending machine: the structure type of the machine is three-roller symmetrical type. the upper roller moves vertically up and down at the symmetrical position in the center of the two lower rollers, which is obtained by screw thread worm transmission. the two lower rollers rotate, and the output gear of the reducer meshes with the lower roller gear to provide torque for the rolled plate. The disadvantage of this machine is that the end of the plate needs to be pre-bent by other equipment.
mechanical three-roll asymmetric type
Main features of mechanical three-roller asymmetrical plate bending machine: the structure of the machine is three-roller asymmetrical type, the upper roller is the main transmission, and the lower roller moves vertically up and down to clamp the plate, and meshes with the upper roller gear through the lower roller gear, and is used as the main transmission at the same time; The side roller moves up and down, and has the dual functions of pre-bending and rolling. Compact structure, convenient operation and maintenance.
2. Hydraulic type
Main features of hydraulic three-roller symmetrical plate bending machine: the upper roller of the machine can be vertically raised and lowered, and the hydraulic transmission of vertical lifting is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod. The lower roller is driven to rotate and meshes with the output gear of the reducer to provide torque for the plate. The lower part of the lower roller is provided with an adjustable idler. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long cans with various cross-sectional shapes.
It is an upward-adjusting symmetrical three-roller plate bending machine, which can roll metal plates into circular, arc-shaped and tapered workpieces 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, aviation, hydropower, chemical industry, metal structure and machinery manufacturing industry.
It is suitable for bending deformation of metal plates. It can be rolled into round, arc and tapered workpieces within a certain range, and has the function of pre-bending the end of the plate. The two lower rollers of this machine are driving rollers that can move horizontally, and the upper roller is driven roller that can move up and down. The moving modes are mechanical and hydraulic. The transmission shafts are connected by universal coupling.
