How to use Composite Manhole Cover Forming Hydraulic Press

   1. No smoking, welding, cutting, hot fire, or storage of flammable and explosive items are allowed around the composite material forming hydraulic press. Take fire prevention measures.

    2. Before operation, all kinds of sundries on the mold should be cleaned first, and any dirt on the hydraulic press rod should be cleaned.

    3. The installation mold of the composite material forming hydraulic press must be carried out under the condition of power failure. It is forbidden to collide with the start button, handle and foot on the foot switch.

    4. Adjust the working pressure of the hydraulic press, but it should not exceed 90% of the rated pressure of the equipment, test a workpiece, and then produce after passing the inspection.

   5. For different hydraulic machine materials and workpieces, when pressing and calibrating, the working pressure, pressure, and pressure holding times and time of the press should be adjusted at any time, and the mold and workpiece should not be damaged.

   6. After the composite material forming hydraulic press is completed, the power supply should be cut off, the hydraulic rod of the press should be wiped clean, the lubricating oil should be added, the molds and workpieces should be cleaned and placed neatly. The scope of application of the single-injection hydraulic press: this series of single-column correction The hydraulic press is a multi-functional small and medium-sized hydraulic press, which is suitable for the correction of shaft parts and profiles and the press-fitting of shaft sleeve parts. At the same time, it can also complete the bending, embossing, sleeve shape of sheet parts, and the stretching of simple parts of a single-column hydraulic press. It can also be used to suppress powder and plastic products with less stringent requirements. This series of products are suitable for machine tools, internal combustion engines, textile machinery, shafts, bearings, washing machines, automobile motors, air-conditioning motors, electrical appliances, military enterprises, assembly lines of foreign-funded enterprises and other industries.  

    7. Install the upper and lower molds to center, adjust the mold gap, and do not allow one side to deviate from the center. After confirming that the mold is fixed, test the pressure again.

    8. Before the composite material forming hydraulic press works, first start the equipment to idle for 5 minutes, and check whether the oil level of the fuel tank is sufficient, whether the sound of the hydraulic oil pump is normal, and whether there is leakage of the hydraulic unit, pipeline, joint and piston.  

    9. Start the equipment to test the pressure, check whether the pressure reaches the working pressure, whether the operation of the equipment is normal and reliable, and whether there is leakage.

    10. The operator of the composite material forming hydraulic press must be trained and master the equipment performance and operation technology before he can work independently.

    11. When the press plate of the composite material forming hydraulic press body slides up and down, it is strictly forbidden to put your hand and head into the work part of the press plate and mold.

    12. It is strictly forbidden to perform operations such as knocking, stretching, welding and cutting, bending and twisting of single-column hydraulic presses while applying pressure.
