Mechanical three-roller plate rolling machine is divided into symmetrical and asymmetrical type.
1. Symmetrical type: The structure of the machine is three-roller symmetrical type, the upper roller is vertically symmetrical at the center of the two lower rollers for vertical movement, through the rod obtained by the transmission of the female worm. The two lower rollers make rotary movements. The output gear of the reducer meshes with the lower roller gear to provide torque for the rolled sheet. The disadvantage of this machine is that the end of the sheet needs to be pre-bending with the help of other equipment.
2. Asymmetrical type: The structure of the machine is asymmetrical three-roller, the upper roller is the main transmission, the lower roller moves vertically to clamp the plate, and the lower roller gear and the upper roller gear mesh, At the same time as the main drive; side rollers for tilting movements, with dual functions of pre-bending and rolling. Compact structure, convenient operation and maintenance.
Hydraulic three rollers plate rolling machine: the upper roller of the machine can be vertically lifted, and the hydraulic drive of vertical lift is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; Provides torque for the coil, there is a supporting roller under the lower roller, and it can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product, and is suitable for various long-shaped tanks with various cross-sectional shapes.
This machine is an upward-adjusting symmetrical three-roller plate rolling machine, which can roll metal plates into circular, arc and conical workpieces within a certain range. The two lower rollers of this model are driving rollers and the upper rollers are driven rollers. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.
This machine is suitable for bending and deformation of metal plates, can be rolled round, arc and conical workpiece within a certain range, and has the function of pre-bending at the end of the plate. The upper roller is a driven roller that can move up and down. There are mechanical and hydraulic movement modes, and the drive shafts are connected by universal couplings.
