There are many types of hydraulic woodworking cold press in the market, usually screw type and hydraulic type. Hydraulic cold press has the characteristics of small noise and fast lifting speed. When hydraulic cold press is in operation, it needs to be equipped and debugged to ensure that the cold press is in good condition. These days, we often receive messages from some customers about this problem. Today, the editor will lead us to follow us. Let's learn from our operators.
Operating Principle of Hydraulic Cold Press:
According to the restriction process, the main cylinder of hydraulic press can complete the basic operation cycle of fast downward speed, deceleration restriction, pressure holding delay, pressure relief return trip and discontinuity (arbitrary orientation), and the pressure, speed and pressure holding time need to be able to be dispatched. The ejection cylinder is mainly used to eject the workpiece, which requires complete ejection, return and intermittent action. For example, when the sheet is stretched, the lifting, interruption and pressure return of the ejector cylinder are also required. Sometimes the blank holder is used to press the blank tightly to avoid wrinkling around the blank.
Hydraulic press takes the main actuator (main cylinder) in main motion or the larger pressure (tonnage) output as the primary specification of hydraulic press, and has been serialized. The tonnage of the jacking cylinder is usually 20%-50% of the tonnage of the main cylinder. The main tonnage of the ejector cylinder of the extruder is about 10%. The tonnage of blank holder of double-action drawing hydraulic press is generally about 60% of the tonnage of drawing cylinder.
The speed of the main cylinder is confirmed by the requirement of pressure processing technology. Generally, in the hydraulic system directly supplied by the pump, the speed of its working stroke does not exceed 50mm/s, the speed of its fast advance does not exceed 300mm/s, and the speed of the hydraulic press is equal to the speed of its fast retreat.
Equipment and commissioning of hydraulic cold press:
Pressure holding time can be set according to practical needs: first select the time mode: "hours h. minutes M. seconds S". The "99.99 hours" can be set when the time value is large. At the end of the holding time, the buzzer sounds, indicating that the work has been pressurized. It is forbidden to set the time as "0000".
Before pressing the workpiece, hydraulic cold press needs to select the correct position according to the workpiece's size and height, and forbid the left and right and the front and back edges。 The left and right uneven pressing workpiece is forbidden。
In order to ensure the safety of operation, a detailed and comprehensive inspection should be carried out before the cold press is actually used.
Check the safety protection equipment is correct and reliable。 Check the transmission of the machine tool and whether the connecting parts are tightened。 Check the normal pressure of the hydraulic system。 Whether the oil pump steering is correct or not。 Check whether the lifting action is reliable。 At the end, the empty machine tool is operated once to see if the whole program action is correctly arranged according to the correct method。
