Presses are used in different industrial production scenarios, but traditional presses have incomplete functions and complex operating procedures, making it difficult for staff to perform production. With the development of science and technology, the types of presses continue to increase, and hydraulic ball joint presses have emerged. This type of press is easy to operate, clean, and easy to maintain, and has become an indispensable tool in industrial production.
What kind of manufacturing process does the hydraulic ball joint press use?
How does the hydraulic ball joint press work?
How does the hydraulic ball joint press operate the oil return valve?
The hydraulic ball joint press is based on the production and processing requirements. The main cylinder can go down faster, reduce speed, make pressure hold delay, pressure relief, return stroke, terminate (any position), basically work cycle, and pressure, speed, and pressure hold The time needs to be adjustable.The eject hydraulic cylinder is primarily used to eject the workpiece and must be able to achieve eject, retract, and exit. For example, when the sheet metal is stretched, auxiliary actions such as lifting, stopping and pressure return of the ejector hydraulic cylinder are required. Sometimes the blank is pressed down firmly with a hold-down to avoid the wrinkles around it.
The hydraulic ball joint press takes the large working pressure (tonnage) that may be output by the main actuator (master cylinder) in the main motion as the main specification of the hydraulic press, and it has been serialized. The tonnage of the ejector cylinder is often 20% to 50% of the tonnage of the main cylinder. The injection cylinder of the continuous extruder can choose about ten% of the primary tonnage. The tonnage of the blanking cylinder of the double-acting hydraulic stretching press is usually about 60% of the tonnage of the stretching cylinder.
The operating principle of the hydraulic ball joint press is hydraulic transmission; the hydraulic pump is driven by the engine, through the reversing valve, speed regulating valve, pressure regulating valve, safety valve, and other equipment, as well as the control of electronic components, and finally, the mechanical movement is realized through the hydraulic cylinder. Their strength is quite large because they are hydraulic transmission, the advantage of hydraulic is high transmission pressure; because the medium is usually hydraulic oil, lubrication is realized during transmission; the resistance of the equipment is reduced; their pressure is generally 10-80Mpa; Of course there is higher pressure.
After the test piece is broken, slowly unscrew the oil return valve to return the oil from the oil cylinder to the oil tank. At this point the pendulum slowly descends and the active needle on the dial returns to the zero position. However, it should be noted that it is not necessary to completely drain the hydraulic oil in the cylinder to make the working piston fall too low, as long as it can accommodate the next test piece and set it smoothly. After placing the next test sample, close the oil return valve and raise the working piston, maintaining the original speed and load. After the work is finished, the oil delivery valve can also be closed (if the oil return valve is not opened at this time, the working cylinder has a low-pressure oil supply to make the piston rise without load).
