HOGI CNC hydraulic 4-roller Plate rolling machine
1. Overview of the machine
1-1. The machine is fully hydraulically driven and digitally controlled. It has an advanced structure, superior performance, and high efficiency. It is at the leading level in the international and domestic industries.
HOGI CNC hydraulic 4-roller plate rolling machine has the following characteristics:
1. The side rollers swing linearly, and the pre-bending effect is good
2. The pressure roller and the rollers on both sides use hydraulic distribution valves and displacement sensors to ensure synchronization.
Features of this machine
1. Full hydraulic drive, high efficiency and energy saving (drive power is equivalent to 60% of traditional ones), safer and more reliable during rolling than other types of plate rolling machines.
2. Permanent lubrication technology (no need to add oil during the life of the bearing)
3. Adjustable clamping pressure (no slippage, productivity is 50%-80% higher than that of three-roller plate rolling machine), the clamping force between the upper and lower rollers on the plate can be adjusted by the hydraulic station pressure regulating valve to adjust the corresponding required pressure when rolling plates of different thicknesses and widths.
4. It can roll a cylinder 1.5 times the diameter of the upper roller, and the straight edge length of the rolled plate end when pre-bent is smaller than that of other types of plate rolling machines.

4. Main structure
The main structure of the equipment is composed of upper roller device, lower roller device, side roller device, main transmission device, tipping device, left and right side frames and chassis.
Advantages:
Adoption of new rolling bearings
Our company has also adopted a number of energy-saving measures on the four-roller plate rolling machine. The new bearings (rolling bearings) for rolling mills are used on the upper, lower and side rollers, which greatly reduces the power of the main motor. At the same time, the non-slip conditions are greatly improved. When rolling symmetrically, the clamping force of the lower roller can be greatly reduced.
It is energy-saving and can roll thinner steel plates and smaller diameters.
Transmission system
Main drive
The upper roller is the active roller, which is directly coupled and driven by a hydraulic transmission device (including planetary reducer, hydraulic motor, balance valve, overload valve, etc.). The four-roll material is 42CrMo forging parts, which are made by rough processing, quenching and tempering heat treatment (HB280-300), and fine processing.
The electric system controls the hydraulic system to compensate automatically, and the synchronization precision of the side roller and the lower roller is kept within 0.5mm. Digital display, each mechanism action displacement and digital synchronization. The electric system has an independent operating table, which can be moved.
Wider range of plate diameter
Ordinary three-roller plate rolling machine two lower rollers for the active rollers, the upper rollers for the passive rollers, roll thin plate and small diameter workpiece is easy to slip. Standard regulations, the thickness of the rolled plate can not be less than the parameters of the maximum thickness of the rolled plate 1 / 3; the minimum diameter of the roll for the upper roller diameter of 2.5 times. And downward adjustable four-roller plate rolling machine on the upper roller for the main drive roller. Allowed to roll the minimum thickness of the parameters of the maximum thickness of 1 / 5 of the rolled sheet, the minimum roll diameter can be up to 1.5 times the diameter of the upper roll. It can also be equipped with inner and outer pallets to meet the rolling of thin plates and large diameter workpieces.
