The reason for the bending of the slitter blade

When the slitter machine processes the sheet, if the speed of the rectifying device is adjusted too quickly or too slowly, the guillotine will bend. First of all, the defects of the sheet must be checked, and then the accuracy of the metal slitting machine is adjusted, and then the winding and tension of the sheet material are controlled. Of course, specific problems must be analyzed in detail.
The metal sheet itself is not even. When the coil is rolling, the internal stress is not completely eliminated. The internal stress will act on the boring tool when it is sheared to make it bend. If the plate has outwardly bent outward forces on both sides, the slats will become bent.
The spurs of the slitter plate make the boring bar bent. When the slitting machine slits the plate, the clearance of the razor blade is not adjusted properly, resulting in burrs. The larger the gap is, the larger the burr will be, and the larger the burr will be when winding. Often because of the burr of the sheet, the edges will bend when stretched.
The uneven gap between the upper and lower blades results in the bending of the file. Since the slots on the left and right sides of the feed slot are relatively large, the indentation will be larger, so that the extent of roll expansion will be relatively large, and bending of the file will naturally occur. When the boring bar is bent due to uneven tension, the tension of the baffle will increase during winding, so that the unilateral tension will bend the boring bar.
