The Common Structure of CNC Hydraulic Press

The CNC hydraulic press body includes the upper beam, the slider, the table, the column, the tightening nut and the adjusting nut. The upper beam and the table are fixed frames composed of uprights and fastening nuts. The precision of the machine is adjusted by adjusting the nut and the tightening nut fixed on the upper end; the sliding block and the master cylinder piston are connected by the flange and the screw and move up and down by the four columns.

The Common Structure of CNC Hydraulic Press

The plunger cylinder of the CNC hydraulic press is fixed by screws between the cylinder body and the upper beam. There is a filling valve at the tail of the master cylinder, a plunger is set in the master cylinder, and a two-way combined seal is adopted to ensure that the oil cylinder does not leak under high pressure.

The hydraulic system of CNC hydraulic press is composed of valve body, piston, main spool, unloading spool, etc. When the slider falls rapidly, the extracted oil cannot be supplied to the upper chamber of the master cylinder in time, resulting in negative pressure, so that the main valve sucks, a large amount of oil into the upper chamber of the master cylinder. In the reverse direction, the main spool is opened by the controlled oil, and a large amount of oil in the main cylinder returns to the filling cylinder.

The ejector cylinder of the CNC hydraulic press is installed on the base, the worktable and the lower top plate are arranged on the top, and the T-shaped groove is arranged on the worktable, and its size is the same as that of the slider.
