1) The installation of molds for hydraulic presses must be carried out under power-off conditions, and it is prohibited to collide with the start button, handle, or use foot pedals on the foot switch;
2) Install the upper and lower molds to align, adjust the mold clearance, and do not allow unilateral deviation from the center. After confirmation, press the mold again;
3) Start the equipment for pressure testing, check whether the pressure reaches the working pressure, whether the equipment operates normally and reliably, and whether there is any leakage phenomenon;
4) Adjust the working pressure, but it should not exceed 90% of the rated pressure of the equipment. Test the pressure of one workpiece and produce it after passing the inspection;
5) For different hydraulic press profiles and workpieces, during pressing and calibration, the working pressure of the press and the number and time of pressure application and holding should be adjusted at any time, ensuring that the mold and workpieces are not damaged.
