CNC four-roller plate rolling machine lubrication importance

CNC plate rolling machine is a kind of common forging and pressing machinery that bends plates into cylinder, arc, sphere, cylindrical or other shapes. The performance is widely used in manufacturing, boiler steam, chemical, non-metallic structure and machinery manufacturing.

Four-roller coilers can be bent symmetrically or asymmetrically according to the arrangement of the adjustment position of the rollers on both sides, so this four-roller coiler can roll into an ideal cylinder with a small theoretical remaining straight edge in one go, and compared with the symmetrical three-roller coilers do not need to use a press to pre-bend the end of the plate.

It also has pre-bending function at the end of the plate. Small remaining straight edge and high efficiency. Pre-bending is achieved by the lower roll rising and clamping the end of the plate, and the side roll tilting up to achieve the pre-bending of the plate end. The machine’s lower roll and side roll lift displacement is controlled by intelligent PLC programmable controller, automatic leveling, screen digital display, synchronization accuracy ±0.15㎜. The lower and side rollers of the machine can be tilted at one end, and can be raised and lowered at the same time in the tilted state.

The four-roller plate rolling machine is suitable for bending and forming of metal plates, and can roll round, curved and certain range of conical workpieces, and has the function of pre-bending of plate end, small remaining straight edge, high working efficiency, and can roughly level the metal plates on this machine.

The structure type of four-roller plate rolling machine is four-roller type, the upper roller is the main drive, through the output gear of the reducer and the upper roller gear mesh, to provide torque for rolling plate; lower roller for vertical lifting movement, through the hydraulic cylinder hydraulic oil acting on the piston and get, in order to clamping plate, for hydraulic transmission; in the lower roller on both sides of the side roller and along the rack guide for tilting movement, through the filament master worm gear transmission; the machine The advantage is that the plate end pre-bending and rounding can be carried out on the same piece of equipment.

The advantages of CNC four-roller plate rolling machine performance.

1. The choice of excellent integrated hydraulic transmission system, credibility is good.

2. Adjustable shear angle, reduce the distortion of thick plate deformation.

3. The upper knife table selected inward tilting structure, conducive to drop material, enhance the precision of the production.

4. The use of three-point support point linear guide, clear the support point gap, improve the cutting quality.

5. The knife head gap handle adjustment is fast, precise and convenient.

6. Rectangular frame cutter head. All four tooth surfaces can be applied, long service life.

CNC plate rolling machine each drive before, need to check whether the oil pool is short of oil, and according to the lubrication chart shown, use clean oil for a refueling. The lubrication device of the plate winding machine generally includes: tumbling side bearing sleeve, set in the tumbling side bearing sleeve inside the tumbling side copper sleeve.

Among them, the overturning side of the copper sleeve inserted inside the upper roll, overturning side of the outer side of the copper sleeve covered with overturning side bearing sleeve gland, and the overturning side of the copper sleeve and the overturning side of the bearing sleeve fixed as a whole; the overturning side of the copper sleeve of the inner and outer wall with oil channels and oil storage tank.

When in use, a pressure injection oil cup is installed on the side of the fixed side bearing housing, and when lubricating oil is needed, oil is injected into the inside of the overturned side copper sleeve through the oil gun; it is used to lubricate the upper roller during the rolling process; the side of the overturned side bearing sleeve is provided with an oil injection port, and the oil injection port is covered with an oil window sealing cover and fixed, so when lubricating oil is injected into the inside of the overturned side copper sleeve, the oil window sealing cover is opened and oil is injected, and then covered with an oil window sealing cover. The oil window seal cover is fixed.
