Mechanical knowledge base: "rolling machine"

The Rolling Machine is a shaping machine that continuously bends the sheet material, and has various shapes such as rolled O-shape, U-shape, and multi-section R.

How winding machine works

The upper roller of the coiling machine acts on the piston in the symmetrical position of the two lower rollers by the hydraulic oil in the hydraulic cylinder to perform vertical lifting movement. The gears of the lower gears driven by the final gear of the main reducer engage the cooperative rotary motion of the two lower roller gears to provide torque for rolling the plate. . The flat metal plate of the coiling machine passes through the three work rolls (two lower rolls and one upper roll) of the coiling machine, and the metal plate passes through multiple passes by means of the lower roll of the upper roll and the rotation of the lower roll. Continuous bending, producing permanent plastic deformation, rolling into the desired cylinder, cone or part thereof. The disadvantage of the hydraulic three-roller coiler is that the end of the sheet needs to be pre-bent by means of other equipment. The coiling machine is suitable for large coiling machines with a coil thickness of 50 mm or more. A row of fixed rollers is added at the lower part of the two lower rollers to shorten the span of the two rollers so as to improve the accuracy of the rolled workpiece and the overall performance of the machine.

Type of coiler

Bending machines have different types depending on the field of use. The three-roller and four-roller coiler were divided from the number of rolls. The three-roller is divided into a symmetrical three-roller coiler, a horizontal down-type three-bar coiler, an arc down-type coiler, a top-roller universal three-roller coiler, and a hydraulic CNC coiler. Separate mechanical and hydraulic type from the transmission.

According to the development of the coiling machine, the upper roller universal type is the most backward, the horizontal downward type is slightly advanced, and the arc type is the highest.

Three-roller coiler

Three-roll bending machine with mechanical and hydraulic: mechanical three-roll bending machine is divided into symmetrical and asymmetric

Mechanical Three-Roll Symmetrical Bending Machine: Mechanical Three-Roll Symmetrical Bending Machine Features: The machine is of three-roll symmetrical type. The upper roller moves vertically at the symmetrical position of the two lower rollers through the wire. The female worm gear drives and the two lower rollers make a rotary motion, and mesh with the lower roller gear through the output gear of the speed reducer to provide torque for rolling the 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 coiler

Mechanical three-roller asymmetrical 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 lifting movement, in order 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. Technical parameters: specification model roll thickness

Hydraulic three-roller coiling machine

The main features of the hydraulic three-roller symmetric coiler are: the upper roller of the machine can be vertically lifted and the vertical lift is driven by the 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 meshes through the reducer. 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 the long length of various cross-section shapes

In order to adjust the symmetrical three-roller coiling machine, the metal sheet can be rolled into circular, arc-shaped and conical workpieces within a certain range. The two rolls under this model are the active roll and the upper roll is the driven roll. 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.
