The plate bending machine is a kind of equipment that uses a work roll to bend the sheet metal. It can form different parts such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate bending machine is the action of the external force such as hydraulic pressure and mechanical force to move the work roll so that the sheet is bent or bent. According to different shapes of the work roll rotation and position changes, can be processed elliptical parts, arc parts, cylindrical parts and other parts.
Plate Bending Machine has different types depending on the field of use.
Divided from the number of rolls into three-roll Plate Bending Machine and four-roll Plate Bending Machine.
The three-roller is divided into three types: Plate Bending Machine, Plate Bending Machine, Plate Bending Machine, Plate Bending Machine, and Plate Bending Machine.
Separate mechanical and hydraulic type from the transmission.
According to the development of the Plate Bending Machine, the top roller universal type is the most backward, the horizontal down type is slightly advanced, and the arc down type is the highest.
Three-roll Plate Bending Machine has 1, mechanical and 2 hydraulic
1. The mechanical three-roller coiler is divided into symmetrical and asymmetrical.
Mechanical Three-Roll Symmetric Plate Bending Machine
Mechanical Three-Roll Symmetric Plate Bending Machine Features: The machine structure is a three-roller symmetry type. The upper roller is vertically lifted at the symmetrical position of the two lower rollers. It is obtained through the wire rod worm drive and the two rollers are Rotary motion, meshing with the lower roller gear through the output gear of the speed reducer to provide torque for the rolled plate. The disadvantage of this machine is that the end of the sheet needs to be pre-bent by means of other equipment.
Mechanical three-roller asymmetrical
Mechanical three-roll asymmetric type Plate Bending Machine main features: The machine structure type is three-roll asymmetric type, the upper roller is the main drive, the lower roller vertical movement to clamp the plate, and through the lower roller gear meshes with the upper roller gear , At the same time as the main drive; side roller for tilting movements, with pre-bend and roll circle dual function. Compact structure, easy operation and maintenance.
2, hydraulic type
Hydraulic three-roll symmetrical Plate Bending Machine main features: The machine can be vertically lifted, vertical hydraulic lifting hydraulic drive, through the hydraulic cylinder hydraulic cylinder piston rod and obtained; the lower roller for rotation driven through the reducer output gear meshing, Provides torque to the coils, with rollers on the lower roll and adjustable. The upper roller is in the form of a drum, which improves the straightness of the product and is suitable for cans of various cross-sectional shapes with long specifications.
Up-regulation symmetric three-roll Plate Bending Machine can roll metal plates into round, arc and conical workpieces within a certain range. This model uses two rollers as the active roller and the upper roller as the driven roller. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.
Suitable for bending deformation of sheet metal, can be rolled round, arc and a conical workpiece within a certain range, and has the pre-bending function of the end of the plate, the two lower rollers of this model can be horizontally moved by the driving roller. The roller is a follower roller that can be moved up and down. There are mechanical and hydraulic methods of movement. The drive shafts are connected by a universal coupling.
