Preparations before starting: Check whether all parts are abnormal, and the fastening screws (cover) must not be loosened. The brake should be normal and reliable. Strictly adjust the distance of the reel according to the thickness of the printing plate, and overload operation is not allowed. Can not crimp the workpiece higher than the rigidity category. Too many accidents occurred during operation: the workpiece must be firmly placed, and all parts must be checked for abnormalities after placement. The fastening screw (cover) must not be loosened. The brake should be normal and reliable. Strictly adjust the reel distance according to the thickness of the printing plate, no overload operation. Can not crimp the workpiece higher than the rigidity category.
The operation of the three-roll bending machine is too small: Before starting the operation, the workpiece must be firmly placed, and the machine must be placed in the correct position, and the signal should be clearly visible, and a person should be appointed to direct it. Do not put your hands on the rolled steel plate, and do not use templates to check roundness. When rolling a workpiece that is not round enough, when rolling to the end of the steel plate, a certain margin should be reserved to prevent the loss of the workpiece and injury. When working, it is strictly forbidden to stand on the workpiece, nor to find the roundness on the rolled cylinder. When rolling thick cylinders with larger diameters or workpieces with higher material strength, the number of moving rolls should be reduced and rolled several times. When rolling a narrow cylinder, it should be placed in the middle of the roll. After the workpiece enters the reel, please be careful that your hands and clothes are caught by the reel. Too many shutdowns of the three-high Nantong plate mill. If you find that the machine is running loudly, you should turn it off immediately for inspection and adjustment. Turn off the switch to cut off the power. Arrange the workpiece to the designated position after shutdown.
