Due to the different fields of use, the types of aluminum sheet bending machines are different. According to the number of rolls, it is divided into three-roll aluminum plate forming arc bending machine and four aluminum plate forming arc bending machine. Top-roller three-roller aluminum plate forming arc bending machine and hydraulic CNC aluminum plate forming arc bending machine. Mechanical and hydraulic types separate from the gearbox.
According to the development of the aluminum plate pressing and bending machine, the upper roll universal type is backward, the horizontal downward type is slightly advanced, and the arc type is high.
Three-roll aluminum sheet bending machine, 1 mechanical and 2 hydraulic
1. Mechanical three-roller aluminum plate forming arc bending machine is divided into symmetrical and asymmetrical.
Features of mechanical three-roll symmetrical aluminum plate pressing and bending machine: This machine is three-roll symmetrical. The upper roll moves vertically at the symmetrical position of the two lower rolls. It is obtained by a screw-worm drive, with two rollers working together. Rotational motion, through the output gear of the reducer meshing with the lower roller gear, provides torque for the rolled plate. The downside of this machine is that the ends of the paper need to be pre-bent by other equipment.
The main features of the mechanical three-roll asymmetric sheet aluminum plate pressing and bending machine: the structure of the machine is a three-roll asymmetric type. Roller gears meshed simultaneously with main drive; side roller pre-bend and roll features for tilt motion. Compact structure, easy to operate and maintain.
The main features of the hydraulic three-roller symmetrical aluminum plate forming arc bending machine are: the upper roller of the machine can be lifted vertically, the vertical lift is driven by hydraulic pressure, and the hydraulic oil in the hydraulic cylinder acts on the piston rod; the lower roller is driven to rotate, and the output gear passes through The reducer is engaged. To provide torque to the coil, there are rollers on the lower roll and can be adjusted. The upper roller is in the form of a roller, which improves the straightness of the product and is suitable for cans with long cross-sectional shapes.
In order to adjust the symmetrical three-roller aluminum plate forming arc bending machine, the metal sheet can be rolled into a range of arc, arc and conical workpieces. The two rollers under this model are the driving rollers and the upper roller is the driven roller. Widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.
It is suitable for the bending deformation of metal sheets, and can be used for round, arc and conical workpiece winding within the range, and has the function of pre-bending the end of the sheet, and the two lower rollers of this model can move horizontally to drive the drum. The scroll wheel is a driven scroll wheel that can move up and down. The aluminum plate forming arc bending machine has mechanical and hydraulic movement methods. The drive shaft is connected by a universal joint. The S350 series is a new generation of vector inverters with the following features:
