The working principle and matters needing attention of single column hydraulic press


What is the working principle of a single-column hydraulic press? How does a single-column hydraulic press work? A single-column hydraulic press is a device that uses liquid to transfer pressure. The transfer of the working pressure of the liquid in the closed packaging container can follow Pascal's law. The hydraulic hydraulic transmission device is composed of power mechanism, control mechanism, actuator, auxiliary mechanism and working medium.single column hydraulic pressIt usually refers to hydraulic pumps and hydraulic motors. Hydraulic pumps and hydraulic motors are energy conversion devices in hydraulic systems. The difference is that hydraulic pump drive motors can convert mechanical energy into oil pressure. Hydraulic systems are power units and hydraulic motors are oil. It can be converted into mechanical energy, which is the realization of hydraulic systems.

Hydraulic pumps and hydraulic motors commonly used in hydraulic control systems are generally of a volumetric type, and their basic working principle is to use changes in the sealing volume to suck and press oil. In principle, most hydraulic pumps and hydraulic motors are mutually beneficial, that is, the input pressure oil, the hydraulic pump enters the hydraulic motor, and can output speed and torque, but in structure, there are some differences between the hydraulic pump and the hydraulic motor.

  single column hydraulic pressIt has its own power mechanism and electrical information system, and adopts centralized management control buttons, which can realize the adjustment of manual and semi-automatic working and living styles. The working environment pressure, pressing speed, no-load fast drop and slow stroke and range of the machine can be adjusted by students according to different process design requirements, and the ejection process can be completed in three ways: removal and stretching process. Each process is of constant pressure, and there are two process actions to choose from. The constant pressure molding process has ejection delay and automatic return after pressing. The single-column hydraulic press has a wide range of versatility and is suitable for the processing and molding of various plastic materials, such as extrusion, bending, folding, stretching, etc. At the same time, the hydraulic press can also be used for the molding of various plastics and powder products. In addition, the single-column hydraulic press technology can also be used for the calibration, stamping and forming of enterprise products.

Problems needing attention in the operation of single column hydraulic presssingle column hydraulic pressOperation management personnel need to be trained to master the performance and operation technology of relevant equipment before operation. Before the operation of the single-column hydraulic press, clean up all kinds of other debris on the mold and dry any biological dirt on the hydraulic press rod.

The installation mold of the single-column hydraulic press needs to be carried out in the case of power failure, and it is forbidden to collide with the start button, handle and pedal on the foot switch. Before the single-column hydraulic press works, start the equipment and idle for 5 minutes. At the same time, check whether the oil level of the oil tank is sufficient, whether the sound of the oil pump is normal, and whether the hydraulic control unit, pipelines, joints and pistons are leaking. Center the upper and lower molds, adjust the mold gap, and do not allow one-way deviation from the center. After confirming that the mold is fixed, test the mold pressure. 

Start the equipment pressure test, check whether the pressure reaches the working pressure, whether the equipment is normal and reliable, and whether there is leakage. Adjust the working pressure, but should not exceed 90% of the rated pressure of the equipment. Test the workpiece and produce it after passing the inspection. For different hydraulic presses in enterprises, when using profiles and workpieces, when pressing and correcting, the working environment pressure and the number and time of pressing and holding pressure should be adjusted at any time, and the mold and workpiece should not be damaged. When the body pressure plate slides up and down, it is forbidden to put hands and heads into the pressure plate and the working part of the mold.
