一般的热处理车间通常使用电葫芦提升工件进行淬火,常因下降速度慢而影响质量。我厂工人、技术人员共同设计了液压半自动淬火提升器,不仅保证了质量,也安全,并且减轻了劳动强度。提升器如图1所示。提升器由液压、电器控制(其液压原理图见图2),可完成半自动循环动作。油泵启动后,提升器上升,露出油面,将工件放在托架9上后,按下自动工作按钮,提升器迅速下降,将工件沉到油槽底部,然后在100～150毫米的范围内上下往复运动一段时间,然后沉到槽底静止冷却,待完全冷透后自动升起,
General heat treatment plant usually use the electric hoist to enhance the workpiece quenching, often due to slow down and affect the quality. I plant workers, technicians jointly designed hydraulic semi-automatic quenching riser, not only to ensure the quality, but also safety, and reduce labor intensity. Lifter shown in Figure 1. Lifter hydraulic and electrical control (hydraulic schematic diagram shown in Figure 2), semi-automatic cycle to complete the action. After the oil pump is started, the hoist rises to reveal the oil surface. After placing the work piece on the bracket 9, press the automatic working button, the hoist descends rapidly, sinks the work piece to the bottom of the sump, then moves up and down in the range of 100-150 mm Reciprocating movement for a period of time, then sink to the bottom of the quiescent cooling until completely cold after the rise,
