1. Strictly abide by the safety rules of the machine tool workers and wear labor protection articles as required.
2, before the boot should be the upper and lower mold clean, wipe clean.
3. Check if there are any foreign objects on the racks, stopper racks and sliders. If there are foreign objects, they should be cleaned.
4, according to the thickness of the folded sheet, select the appropriate die, die size is generally equal to or greater than 8 times the sheet thickness.
5. The bending force of the workpiece is obtained from the calculation formula of the bending force of the sheet or the bending force, and the bending force of the workpiece must not be greater than 1000 KN.
6. When bending narrow sheets, the working pressure of the system should be properly reduced to avoid damage to the mold.
7, adjust the slider stroke, should ensure that the adjustment is less than 100, so as not to damage the machine.
8. Before bending, the gap between the upper and lower molds should be adjusted uniformly.
9. When bending, do not put your hand between the molds. Only one piece of material can be folded at a time, and not many pieces are bent at the same time. Check the oil level of the tank and start the oil pump to check for any abnormalities in the hydraulic piping and the oil pump.
10. The bent sheet should be placed in the middle of the mold. The machine should not be unilaterally loaded so as not to affect the accuracy of the workpiece and the machine. If some workpieces need to work unilaterally, the load should not be greater than 250KN, and the two sides must be bent at the same time.
11. Check the oil level of the tank and start the oil pump to check whether there is any abnormality in the hydraulic pipe and the oil pump.
12. Abnormally stop immediately, check the cause and eliminate it in time.
13. After the operation is completed, the oil pump should be turned off, exit the control system program, and cut off the power supply.
