Multi-layer hot press machine startup and automation requirements
Aug 29, 2018

Before the start-up of the multi-layer hot press machine, the heat transfer oil pressure can meet the process requirements, and then effectively maintain the supply; at the same time, the lower surface of the pad on the device is cleaned, the surface of the hot plate is cleaned; During the operation of the machine, the pressure of the accumulator is normal, the oil level of the fuel tank is normal, the transmission parts are well lubricated, the operation is normal, and the electrical equipment is normal.


When using, it is necessary to close the main switch of the multi-layer hot press machine power supply, effectively activate the low-pressure pump, so that the accumulator can reach the required working pressure, open the heat-conducting oil valve, close the heat-conducting oil bypass circulation valve, and heat The hot platen reaches the temperature of the process.


Then according to the process requirements, during the operation process, the time of the machine and the position of the upper and lower pointers of the pressure gauge are effectively adjusted during the operation, and the oil pump motor and the plate feeder are started, and the slabs of the blank are successively entered. Inside the loading machine; start the relevant motor of the hydraulic pump system, effectively open the switch of each solenoid valve and the switch of the time controller, close the press, and start boosting.


The multi-layer hot press machine is an automatic operation. It only needs to open the corresponding automatic control switch, and it can lift and hold pressure according to its process requirements. When the hot pressing cycle is finished, the pressure reducing valve is opened. After the unloader pulls out the backing plate and the reconstituted wooden board, the slab is loaded again to start the second hot pressing cycle.
