Double acting cylinders for calibration machine with sequential jaws for aluminium tubes. The machine is useful for crimping and expanding aluminium tubes during clamping.
At the beginning all tubes will be crimped to obtain an initial dimension for the following expansion.
The 12 sequential jaws are arranged in a circle. Each jaw is powered by a high pressure double-acting hydraulic cylinder. The pressure is generated by a high pressure hydraulic unit with manometer.
The operator can verify the operations by using a wire connected remote control.
