1. Leveling machine functions:
The metal plate is leveled by multiple sets of rollers of the leveling machine to achieve a smooth effect. The quadruple high-precision leveling machine uses support rollers installed between the upper and lower rows of leveling work rollers and support bearings (wheels) to form a four-fold roller structure with two upper and lower rows; the force on the leveling rollers is evenly distributed. , with good structural rigidity, small deflection deformation of the work roll, high leveling accuracy, and stroke harmonic attenuation straightening, which fundamentally solves the common problems of ordinary leveling such as uneven leveling, easy roll marks, workpiece sagging, and sickle bends. It can improve the correction accuracy of the plate and has a wide range of applications. There will be no rolling marks left on the surface of the material and the correction accuracy is high.
2. Mechanism of precision plate leveling machine:
It consists of frame, leveling machine wall panel, leveling roller, support roller, synchronous gear box, universal joint, motor reducer, adjustment lift, control system, auxiliary roller for discharging and discharging materials, etc.
3. Detailed explanation of structural components:
1. Frame part: Welded from Q235 high-quality carbon steel plates and profiles, the surface is processed after high-temperature tempering to ensure stable performance and dimensional accuracy of the frame.
2. Leveling machine wall panel: It is the main part of the leveling machine. It is rough-machined from 45# steel after tempering. The bearing position is fine-machined by CNC computer gongs to ensure processing accuracy.
3. Leveling rollers: ￠50mm *13 pieces, arrangement of leveling rollers: upper 6 (movable) and lower 7 (fixed). The material is high-quality bearing steel GCR15. It is processed after quenching and tempering. The hardness of the roller is 55±2º after vacuum heat treatment. (Bearing steel can be processed to a maximum hardness of 55 degrees, and will easily break when processed to 60 degrees;). The surface of the drum is ground, plated with hard chromium and then finely ground. The hard chromium layer on the surface is ≧0.05mm.
3. Support roller: The support roller is used to support the leveling roller to ensure that the leveling roller does not deform during work. Each of the upper and lower rollers has one set evenly distributed in the middle. The clearances are adjusted before leaving the factory. Customers do not need to adjust. The support roller is composed of multiple roller bearings arranged in parallel, which has high precision and can withstand large forces.
4. Synchronous gear box: The wall panel of the synchronous gear box is made of 45# steel quenched and tempered and processed by CNC computer. The gears are made of high-quality alloy steel 40Crmo quenched and tempered. The surface hardness is above 55º after high-frequency treatment, and the surface is blackened after grinding. There are multiple gears for synchronous transmission, extending out 13 power connectors.
5. Universal joint: used for universal transmission, connected between the gear box and the drum to achieve power transmission, so that the 13 rollers are all power rollers and rotate synchronously. Both sides of the universal joint are connected in a square shape, making it easy to disassemble and replace.
6. Motor reducer: The leveling motor is a 5.5KW motor matched with a 1:59 cycloidal pinwheel reducer that directly drives the synchronous gearbox transmission. The cycloidal pinwheel reducer has high efficiency and stability, with surface output and small backlash and backlash.
7. Adjust the lifter: Adjust the lifter to mainly control the lifting and lowering of the upper roller, and adjust the leveling gap to control the leveling effect. It is composed of four 2.5T worm gear lifters. The handwheel rotates forward and reverse to control the lifting and lowering of the lifters to adjust the leveling effect. There are 4 compression springs installed on the top to eliminate the clearance of the worm gear and achieve precise adjustment.
8. Transmission mode: This model uses imported Japanese sealed bearings to rotate. The bearings have dust covers and sealing rings. The two properties are different, one is dustproof and the other is sealed. Dustproofing is to prevent dust from entering the inside of the motor; sealing not only prevents external dust from entering, but also prevents internal grease from flowing out easily. Grease that is not clean from the outside is not easy to flow in. Ensure the drum rotates smoothly for many years. The service life is at least 8 years, and there is no need to install an additional automatic lubrication system. It is environmentally friendly, energy-saving, and simple and convenient to operate;
9. Control system: This machine uses Delta inverter to control the operating speed, which can be adjusted freely with manual knobs. The main control system is concentrated in an electric control box, which is hung on the side of the machine at a convenient location. The operation panel is simple, easy to understand and easy to operate. Install emergency stop switches at conspicuous locations at the four corners of the machine to ensure safe operation!
10. Auxiliary rollers for incoming and outgoing materials: The rollers are made of thick-walled stainless steel pipes. Both incoming and outgoing materials are equipped with supporting frames to assist in leveling the plates for incoming and outgoing materials.
