Product description

Main advantages


Process flew


1)Uncoiling the coil,the coil is brought by crane and put on the feeding cart.The cart moves the coil and uses its hydraulic cylinder to lift coil at the right height where the feeding platform of cart equals to uncoiler’s core axes, then the axes moves into the inner hole of the coil,the raw-material uploading is finished.

Once accepted the coil, the uncoiling spindle expands and shrinks by rotating the oil cylinder, in order to firmly stuck the coil hole and decoiling by tension.

2)Through the precision leveling machine, when the sheet material enters the feeding roller of the leveling machine, the sheet material enters the leveling roller system, and the sheet material repeatedly yields after the extrusion of the upper and lower leveling roller, so as to achieve accurate leveling.

3)Through the linear guide rail and transmission platform to transport the plate, the plate is transmitted while laser cutting. At the same time, laser marking and labeling can also be carried out.

4)The robot’s gripper is mainly composed of vacuum sucker and electromagnet, and each gripper is controlled uniformly.The the arm’s cylinder drives the vacuum sucker to push out, and separates the leftover materials and finished products, and places them in the designated area.

The gap of vacuum suckers and electromagnets can be adjusted through numerical control system, to meet the shape and size requirements of different products

Note:Functions of marking and automatic stacking are optional.


Feeding lifting system


The feeding trolley is located on the outer end face of the mandrel of the uncoiler, and the hydraulic cylinder lifts the steel coil. When working, hang the coil plate on the tray at the top of the oil cylinder, and the hydraulic cylinder lifts the coil plate to the center of the uncoiler mandrel. After the feeding is in place, the uncoiler will make the arc plate expand and shrink through the oil cylinder for the uncoiler to tighten.  then, the trolley descends, and the trolley returns to the next loading position.

Leveling system

Support-roll-construction,digital displayed  leveling process. When changing the material thickness, it can reach the specified position quickly and simply. With the functions of motor adjustment, intelligent shutdown, forward and reverse one-button conversion, it makes the equipment more efficient and stable operation more convenient.

6-fold 24 rollers leveling equipment, mainly used in stainless steel, Bimetallic Sheet, Galvanized Sheet,  Nonferrous Metal Sheet, And aluminum ,which can keep the surface smooth and avoid surface indentation


Leveling system-Power part

The machine is designed with two-stage power drive. The power of the main motor is transmitted to the power distribution box with gear structure through the reducer. Each leveling work roll has driving force input. The power mechanism, composed of motor, reducer, coupling, power distribution box, universal transmission shaft, drives  the upper and lower rows of work rolls from end of rolls at the same time. The main force is from high-power DC motor, which is responsible for providing power to the leveling unit, at the same time, the DC motor starts at low speed, with high torque and fast response speed when making and breaking frequently. Equipped with high-end digital DC controller, the production line has high production efficiency and good length fixing accuracy.


Leveling system- Rollers

The roller end bearing adopts precision needle roller bearing to connect the roller shaft seat, and the running resistance is small. The upper and lower working rollers and the upper and lower cross beams are provided with middle rollers and support rollers which feature Finish grinding after quenching, and slightly lower hardness compare with work rolls. Most of the bending force generated by the work roll is borne by the middle roll and support roll. The middle roller can also isolate the mark brought by the feedback of the backup idler to the work roller on the plate surface, so as to ensure that the surface is not damaged after passing through the leveler. Multiple groups of support rolls work together with middle roll and work roll to greatly improve the stiffness and strength of work rolls. The height and direction of the idler base are adjusted with wedges, which can not only reduce the deformation of the work rolls, but also easier to adjust. The support roll and the roll shaft base are connected by bearings.


Laser cutting system

The machine adopts professional machine bed structure, aging annealing treatment, high precision rack and rail drive mechanism, plus Yaskawa servo motor, so that all the moving parts run fast and stable. The moving part of the bed is equipped with automatic lubrication system, and the German technical numerical control system makes the cutting of the equipment stable, fast with high precision. 6000W laser tool can cut aluminum plate, carbon steel, stainless steel galvanized plate and so on.
