本发明是用于真空淬火炉加热室装出料的一种装料装置,该真空炉在加热室前面装置油淬室,而油槽则装置在输送通道的下面,以便炉料通过油淬室送入加热室。以前所知的一种装料装置,其所有运动均由液压—气动提升元件来实现,该元件由限位开关直接碰撞加以控制其整个机组均装在真空室中,且工作时期不仅暴露于高温中,而且还暴露于油槽的油蒸汽中,故较易造成差错。如果任何密封套筒或液压系统挠性输送管道损环的话,液压油的泄漏会造成特制淬火油的污染。该装料装置的还有一个缺点是:要把热的炉料从悬臂移至升降台,于是造成时间延迟,这对淬火工件不利。
The present invention is a charging device for charging out of a heating chamber of a vacuum quenching furnace which is equipped with an oil quenching chamber in front of the heating chamber and an oil sump which is arranged below the conveying path so that the charge is fed through the oil quenching chamber Heating room. A previously known loading device in which all movement is carried out by a hydro-pneumatic lifting element which is controlled by a direct impact of a limit switch and whose entire unit is housed in a vacuum chamber and which is exposed not only to high temperatures But also exposed to the oil vat oil mist, it is more likely to cause errors. Leakage of hydraulic oil can result in contamination of the special quench oil if any seal sleeve or hydraulic system flexible delivery line is damaged. A further disadvantage of the charging device is that moving the hot charge from the cantilever to the lifting platform results in a time delay which is detrimental to the quenched workpiece.
