The advantage of DC motors in the production line of unwinding, leveling, and longitudinal cutting lies in their use.
The uncoiling, leveling, and longitudinal cutting production line is a sheet metal processing equipment suitable for surface covering coils in industries such as automobiles and steel plate distribution, which includes uncoiling, cleaning, oiling, leveling, dropping, and palletizing. It has been widely used in automobile manufacturing plants in developed countries.
Use the workshop crane to lift the steel coil onto the steel coil storage platform, and transport the steel coil to the bottom of the double head hydraulic internal expansion unwinding machine by the loading trolley and align it with the middle line of the opening reel. The lifting device of the loading trolley rises and lifts the steel coil, manually aligning the height of the steel coil, and the unwinding heads on each slide move relative to each other. The unwinding heads are inserted into the inner diameter of the steel coil and expanded, firmly securing the steel coil on the unwinding machine. The lifting device of the loading trolley descends and exits the unwinding machine, and the left and right unwinding heads (linkage) of the unwinding machine move along the width of the strip steel, manually completing the width alignment (i.e. aligning the middle line of the steel coil width with the middle line of the unit).
The production line for unwinding, leveling, and longitudinal cutting utilizes the constant torque characteristics of a DC motor and adopts automatic weak magnetic control, which improves efficiency and saves costs. Adopting the cross cutting unit process flow, this unit is used for horizontal coil feeding. After adjustment, the pressure roller is pressed down and the steel coil binding tape is removed; With the support of the opening machine, deep bending roller, and pressure roller, open the steel coil head and guide the plate head into the clamping roller of the initial calibration machine, then into the leveling roller for leveling, and finally retract the opening machine. At the same time as the pressure roller is lifted, the deep bending roller presses down, and the steel plate enters the hydraulic centering device through the initial calibration machine and the loop bridge, and then enters the precision calibration machine and the fixed length shear, completing the threading process; After cutting off the material head, the length measuring device is put into use, and then the automatic cutting can be controlled by the strategic machine. When the number of cuts in the unwinding and leveling longitudinal cutting line reaches the set value, the entire line will automatically stop. The finished materials are lifted out of the workshop crane and packaged. The automation control of the unit is completed by PLC. The setting parameters are inputted through the touch screen human-machine interface, and various parameters can be set according to the pre-set parameter categories.
