HOGI CNC 4-roller plate rolling machine has the function of pre-bending at the end of the plate, which can load the metal plate at one time and complete the pre-bending at the end of the plate and the rolled shape of the workpiece without adjusting the head. The upper working roller of the machine is the main driving roller, the lifting and lowering of the lower roller and both side rollers adopt hydraulic transmission, the lifting and lowering displacements are controlled by computer, automatic leveling and screen display, the tipping and resetting of the overturning bearing body adopts hydraulic transmission, and the tail of the upper rollers is equipped with a balancing mechanism, so that it is easy to unload the rolled up workpiece and the cylinder body. It is equipped with a mobile independent operating table, which can be moved and operated at any time, and the machine is equipped with a safety interlocking device, which is of high technical level, full-featured, high-precision and easy to operate. It is the ideal machine for rolling round, arc and cone-shaped workpieces in energy, transportation, petroleum, chemical, boiler, shipbuilding, ventilation, metal structure and other industries.
HOGI 4-roll CNC plate rolling machine is suitable for bending and forming work of metal plates, it can roll round, arc and a certain range of conical workpieces, and has the function of pre-bending at the end of the plate, the remaining straight edge is small, and the working efficiency is high, and it can be roughly calibrated to the metal plates on this machine.
Four-roller plate rolling machine consists of four rollers, the upper roller is the main drive and the position of the upper roller is fixed, and the two ends of the lower roller are driven by hydraulic cylinders to lift. Then the lower roller down, the two side rollers rise, plate bending rolled into a cylindrical shape. Two side rollers straight line or arc to the upper rollers close to the movement to adjust the curvature radius of the roll.
Advantages of four-roller CNC plate rolling machine:
Can pre-bend the plate end of the metal plate, and the remaining straight edge is small, without the need for additional equipment such as presses pre-bending has a good process adaptability and high efficiency.
Compared with the 3-roller coiler, it can not use other equipment to directly pre-bend the end of the plate, and the remaining straight edge is smaller. This not only improves the quality of the workpiece, but also the process is simple and easy to operate. Rolling machine manufacturers tell you that the four-roller plate shearing machine is a hydraulic transmission, than the mechanical transmission, low noise, high efficiency, low energy consumption, compact structure, maintenance and easy to use. Suitable for heavy workpiece rolling and automation level and high technology level occasions.
HOGI Four-roller plate rolling machine has the function of aligning and clamping the plate, the plate will not slide and run out of shape; it has the function of anti-overload and hydraulic protection; it is easy to be operated with high speed and high efficiency in rolling the plate.
The working principle of the four-roller plate rolling machine, for the plate processing of material properties and shape of the different problems, designed based on machine vision of the four-roller plate rolling machine of the numerical control system, able to detect the curvature of the rolled plate online, and the required shape for comparison, real-time correction of the processing parameters, to solve the problem of changes in the rebound coefficient of the differences in the performance of the plate material in the processing of rolled plate; to complete the linkage of the upper roll and the side roll to solve In addition to round, such as elliptic, parabolic and other anisotropic parts of the rolled parts, to realize the CNC rolled plate processing.
Main drive mechanism
- The upper roller of the four-roller plate rolling machine is the main drive roller, the hydraulic motor drives the roller shaft with a certain speed ratio of the deceleration device, so that the roller shaft rotates at a linear speed of about 4 meters per minute, thus completing the action of the steel plate feeding and so on.
Auxiliary mechanism
- lifting of the lower roller and both sides of the roller, dumping and reset of the head, the above are hydraulic transmission, the lower roller and the side of the roller at both ends can be lifted at the same time, can also be lifted individually.
- The lifting position of both ends of the rollers can be accurately displayed on the operating table.
Hydraulic system
- adopts independent hydraulic pump station consists of oil pump motor, hydraulic valve group, pipeline auxiliary parts and so on.
- ·driven by the motor pump output pressure oil, in order to ensure that the oil is clean, there is an oil filter at the oil pump oil port, from the oil pump out of the pressure oil first into the pressure regulating system, regulating the pressure, and then through the channel block, through the three-digit four-way reversing valve to the cylinder.
- ·hydraulic pump station system production is strictly in accordance with the national standard, line standard implementation, reasonable layout.
- ·Full consideration of high efficiency and energy saving, reduce waste, reduce the heat source.
- ·The system is independent, and the appropriate joints are made of professional sealant to eliminate leakage, and it is easy to repair and maintain.
- ·Among them, hydraulic pumps, hydraulic valves are selected from famous brand series, cylinders for professional hydraulic cylinder factory customized production of matching products, piping arrangement is simple, less leakage, maintenance and commissioning is convenient.
· Each roller lifting synchronization system controlled by PLC, through the hydraulic valve (electromagnetic directional valve, throttle valve, liquid-controlled check valve) and displacement sensor detection feedback, automatic adjustment, synchronization precision is very high.
ELECTRICAL CONTROL SYSTEM
- The electric control system consists of an electric control cabinet, an operating console, and a hand-held control box. The machine control appliances (including PLC) are installed in the distribution cabinet.
- Adopts touch screen display and operation, which is easy to operate. The main circuit adopts three-phase 380V/50Hz AC power, and the motor has short-circuit overheating protection.
- The main original devices adopt Schneider products. It is made in strict accordance with national standards, with reasonable structural arrangement and necessary safety protection measures.
Description of use
- Four-roller plate rolling machine is metal plate bending, correction machinery, dedicated to metal plate forming bending work.
- The machine can complete the pre-bending of plate ends and roll cylindrical and curved workpieces with one feeding, and it can also carry out rough shaping work on metal plates.
- CNC Plate Rolling Machine is widely used in shipbuilding, boiler, aviation, bridge, hydropower, chemical, metal structure and machinery manufacturing industries.
The main features of the equipment
- The roller lifting and inverted head turning of this equipment are executed by hydraulic cylinders. All the manipulation adopts NC electric centralized control, which is convenient to operate and the digital display is eye-catching and intuitive.
- Roller lifting displacement as well as rolling parameters are digitally displayed on the screen, with plate thickness, rolling diameter, material properties are input automatically calculated after the appropriate work roll position is displayed on the touch screen for user reference.
- · At the same time, it also has the status display of each input and output of PLC, which makes the maintenance more convenient.
