Therefore, it is generally a process required for metal processing. One of the processes of heat treatment is quenching. Quenching is the process of heating the workpiece to a certain temperature and then cooling it rapidly to change its structure and properties.

[0003] Based on the quenching process, the workpiece needs to be heated to the critical temperature first and then cooled rapidly. At this time, the workpiece needs to be transferred. At this time, a quenching receiving device is needed to receive the workpiece and transfer it to the cooling position. If the workpiece is transferred entirely by lifting, it will directly affect the transfer efficiency during the work process and may also cause instability during cooling. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are: the workpiece heat treatment quenching receiving device not only improves the transfer convenience, but also improves the overflow water collection capacity and water inlet capacity of the workpiece heat treatment quenching receiving device;

[0014] (1) The connection block is used to complete the left and right connection of the water seepage frame, and the second water seepage hole is opened inside the water seepage frame. The second water seepage hole can be used to perform preliminary water seepage work, and then the heated workpiece is placed inside the lower frame. The upper frame and the lower frame are fixed to each other, and the upper frame and the lower frame are lifted as a whole by using a lifting ring. Then, the lower frame holding the workpiece is lifted to a position above the water seepage frame, and then gradually lowered. During the descent, the second guide wheel cooperates to perform the guiding work, and the first guide wheel is used to move inside the guide groove to form a positioning guide until the lower frame is completely in the water seepage frame. The lifting work is stopped, so that more workpieces can be cooled at one time during the work process, thereby improving the overall transfer convenience during the work process;

After the end, it can be discharged and collected at the side drain port, thereby better improving the overall overflow collection capacity during the working process;

[0016] (3) The connection block is used to complete the left and right connection of the water seepage frame, and the servo motor at the top of the threaded rod is started to drive the threaded rod to rotate. At this time, the threaded rod and the threaded block cooperate with each other, and the guide rod and the sliding sleeve cooperate to guide.
