用途和特點/Purpose And Features

本機是為中、重無內胎車輪輪輞壓平面、沖氣門孔設計的專用雙動液壓機。

本機分為主機、動力機構和電氣控制箱三大部分，具有獨立的液壓傳動裝置和電氣控制箱。

采用PLC控制，可以實現手動調整、自動二種操作規范，并具有超溫保護、緊急停車、過濾器堵塞發訊等功能。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.

特點

本機的工作壓力、工作速度、行程范圍等可根據工藝需要進行調節。

本機滑塊有二根導軌進行導向，當滑塊受偏心載荷時，由二根導軌承受，避免直接作用在活塞桿上，防止活塞桿的偏心磨損和拉傷，提高密封壽命。
