4 Column Deep Drawing Hydraulic Press

Four column hydraulic machine table has a hole role is what? The main role is used to install the hydraulic machine out of the cylinder, this paper will detail introduce it!

Hydraulic cylinder out of the cylinder is used with the mold, and some need to stretch (in the master cylinder down with the top of the cylinder holding the workpiece to maintain a certain pressure to complete the workpiece molding), you can press the workpiece after the workpiece The top of a distance to facilitate the workers out.

Hydraulic cylinder master cylinder movement process is more complex and more steps, but compared to the top out of the cylinder, the top of the cylinder is very simple process of work, and only two steps, and the top of the cylinder movement occurs in the main After the completion of the cylinder movement, followed by the top of the cylinder began to work, between the two can be said to be closely related. The first step of the working process of the hydraulic press is to eject the workpiece. The concrete realization is that when the master cylinder stops moving, the ejector button is depressed and the corresponding three electromagnets are energized, two of which are opened, A hydraulic valve into the valve through the valve into the top of the cylinder cavity, the cavity of the oil flow back to the tank by the valve, the workpiece top out. The second step is to eject the top cylinder, press the back button, the electromagnet power failure, the other several electromagnets, electricity, cartridge valve open, the hydraulic oil into the top chamber by the valve chamber, The flow back to the tank by the valve, the top cylinder back. When these steps are completed, the next step is taken, and then a circulation system is formed to maintain the continuous movement of the hydraulic press machine.
