用途和特点/Purpose And Features

本机是为中、重无内胎车轮轮辋压平面、冲气门孔设计的专用双动液压机。

本机分为主机、动力机构和电气控制箱三大部分，具有独立的液压传动装置和电气控制箱。

采用PLC控制，可以实现手动调整、自动二种操作规范，并具有超温保护、紧急停车、过滤器堵塞发讯等功能。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.

特点

本机的工作压力、工作速度、行程范围等可根据工艺需要进行调节。

本机滑块有二根导轨进行导向，当滑块受偏心载荷时，由二根导轨承受，避免直接作用在活塞杆上，防止活塞杆的偏心磨损和拉伤，提高密封寿命。
