Shanxi Qiu Lin Machinery Co., Ltd. has a total assets of 300 million yuan,
with all kinds of advanced processing and testing equipment, major parts are processed by CNC machining center.
I. Operating procedures
1、Check whether the surface of the platen and the auxiliary laminate (high temperature mylar, etc.) is clean. If there is pieces of wood and dirt, clean them directly. Check whether the auxiliary laminate (high temperature mylar, etc.) is damaged, replace it immediately. Check the heating system of the press whether the heat conduction oil is sufficient. Oil with a depth of 2-5cm should be retained at the bottom of the expansion tank, otherwise it should be added timely.
2、Switch on the power, set the working temperature of the press according to the processing requirement. After this, turn on the circulating pump switch and heating control switch to start the press temperature control system.
3、Remove the protective cover of the time relay panel for pressure holding and timing, and set the pressure holding time according to the processing requirement.
4、 According to the workpiece area and required unit pressure（kg/c㎡）, look up the biggest required force from the pressure curve on the hot press. Adjust the button of pressure controller, the red needle in the pressure controller dial is the upper limit pressure, while the black needle is the system working pressure. Adjust deasil, pressure setting decrease, adjust anticlockwise, setting increase.
5、After finishing the setting, and the temperature reaches the setting point, workpieces can be processed.
Put the workpieces on right position，see blew pictures;
①right position（width way）
② right position（length way）
6、If the workpiece is skewed in the press, please straightened with long wooden strip. The operator is not allowed to touch the platen and leave during press closing. The operator shall pay attention to the working condition of the equipment and the workpiece. In case of any abnormality, stop the closure immediately. It is strictly prohibited to touch the workpiece or the platen and the transmission part by hand during machine closing to prevent extrusion and scalding accidents
7、When finishing the pressure holding time, the press stop automatically, the platen will be lowered, take out the workpiece with a wooden strip
8、After finishing working, clean the platen surface, close the press without pressure. Turn off the heating system and main power until temperature of the press is below 60℃, clean up the working site.
II、Daily maintenance and standard
item | place | standard | time |
1 | Hydraulic system | No leakage, suitable oil quantity | Check every shift and add oil in time |
2 | Heating system | No leakage, suitable oil quantity | Check every shift and add oil in time |
3 | platen | Clean, no dirt | Check every shift and clean up |
4 | Synchronization system | Reliable and flexible | Check every shift and add grease every week |
