    • An inventive automated heat treatment system has a furnace for heat treating forged engine valves, a carry-in mechanism for transporting the forged valves into the furnace, and a carry-out mechanism for transporting heat treated valves out of the furnace. Each of the carry-in mechanism and the carry-out mechanism has a retention mechanism for retaining valves hung, and a transport mechanism for transporting valves to the furnace as they are hung. The furnace has heating means, groups of paired rails for supporting and moving the valves hung in the furnace, and a stopper for controlling the positions of the valves on the rails. The engine valves are maintained hung with their umbrella-shaped portions supported by the respective mechanisms throughout the automated heat treatment processes. Thus, the heat treatment of engine valves is done in a fewer steps than in a conventional system.
    • 本发明的自动热处理系统具有用于热处理锻造发动机阀的炉,用于将锻造阀输送到炉中的携带机构,以及用于将热处理的阀输送出炉的进出机构。 每个输入机构和执行机构具有用于保持阀悬挂的保持机构,以及用于在将阀悬挂时将阀输送到炉中的输送机构。 炉具有加热装置,用于支撑和移动悬挂在炉中的阀的成对轨道组,以及用于控制在轨道上的阀位置的止动器。 发动机阀门在整个自动化热处理过程中保持悬挂在其各自机构支撑的伞形部分上。 因此,发动机气门的热处理以比传统系统更少的步骤完成。
