Summery/Purpose And Features

This machine is a kind of special double-action hydraulic press which is used for valve hole flattening and punching of medium & heavy duty commercial vehicle rim.

This machine is composed of host device, hydraulic driving device and electrical cabinet.

Its operation can be controlled by PLC system which can switch between auto and manual, and has multiple functions including over temperature protection, emergency stop, filter clogging alarm and so on.

Its operating pressure, working speed and stroke range can be adjusted according to the requirements of technology and processing.

Its host device’s slider mounted 2 guide way which used for guiding, and the 2 guide way can bear eccentric force when slider suffer eccentric load, to avoid direct effect on the piston rod, to prevent the eccentric wear and strain of piston rod, so this design can increase service life of seal.
