For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0028] Referring to Figure 1 And Figure 2 The utility model discloses a quenching equipment for metal heat treatment, including bottom plate 1 and the water inlet and outlet device 2 of installing through bottom plate 1, the water tank 3 of rotating installation through water inlet and outlet device 2, the both ends of the top of water tank 3 are provided with the slot 311, and the quenching basket device 4 of rotating setting is provided at the slot 311, and the electric push rod 5 of rotating connection is provided between water tank 3 and quenching basket device 4, when the electric push rod 5 retracts to the extreme position, quenching basket device 4 removes from water tank 3, when the electric push rod 5 extends to the extreme position, the partial bubble of quenching basket device 4 is immersed in water tank 3.

[0029] Referring to Figure 6 And Figure 7 As shown in the above technical scheme, the left and right two quenching basket devices 4 are provided, and in actual application, one of the quenching basket devices 4 corresponds to the heat treatment furnace, and the workpiece heated in the heat treatment furnace is directly put into the quenching basket device 4, after being put in, the water tank 3 is rotated, so that the quenching basket device 4 loaded with the workpiece is transferred to the side away from the heat treatment furnace, and waits for quenching to end, and the other idle quenching basket device 4 is on standby at the outlet of the heat treatment furnace.

[0030] The above technical scheme can realize continuous batch quenching, and facilitates the export of the workpiece after quenching.

[0031] Referring to Figure 3 And Figure 4As shown, the bottom center of the sink 3 is provided with a connecting sleeve 31, the water inlet and outlet device 2 includes an outlet pipe 21 and an inlet pipe 22, the lower end of the outlet pipe 21 is closed, the upper end of the outlet pipe 21 is inserted into the sink 3 through the connecting sleeve 31, bearings 23 and shaft seals 24 are matched between the outlet pipe 21 and the connecting sleeve 31, the shaft seals 24 are sealed to the inner side of the bearings 23, the lower end of the outlet pipe 21 is fixedly connected with the bottom plate 1, a flow-out pipe 25 is arranged at the position close to the bottom of the outer wall of the outlet pipe 21, the inlet pipe 22 is a bent pipe, the inlet pipe 22 is inserted from the outer wall of the outlet pipe 21, one end of the inlet pipe 22 extends upward to the outside of the outlet pipe 21, the other end of the inlet pipe 22 is connected with a water supply device, a water spraying pipe 26 is annularly arranged at the outer wall of the end of the inlet pipe 22 away from the water supply device, the water spraying pipe 26 is obliquely arranged downward away from the end of the inlet pipe 22, and the height of the end of the water spraying pipe 26 is higher than the height of the outlet pipe 21.

[0032] In the above technical solution, the height of the upper end of the outlet pipe 21 needs to be lower than the height of the lower edge of the slot 311, about 5 cm, so as to avoid water overflow caused by the quenching basket device 4 entering.

[0033] In the above technical solution, the water inlet flow of the inlet pipe 22 is less than the water outlet flow of the outlet pipe 21, and in the quenching process, the inlet pipe 22 is kept in a continuous water inlet state, so that the water temperature in the sink 3 is always in a low temperature state.

[0034] Referring to Figure 2 As shown, the quenching basket device 4 includes a first bottom plate 41, the first bottom plate 41 includes a flat plate portion 411, an inclined plate portion 412 and a basket portion 413, the flat plate portion 411, the inclined plate portion 412 and the basket portion 413 are of an integrated structure, a surrounding plate 414 is arranged at the outer side of the first bottom plate 41, a water passing hole 415 is arranged at the position corresponding to the inclined plate portion 412 of the surrounding plate 414, a rotating plate 416 is arranged at the bottom corner position of the first bottom plate 41, a rotating shaft 417 is matched between the rotating plate 416 and the slot 311, the electric push rod 5 is rotationally connected between the first bottom plate 41 and the outer wall of the sink 3, when the electric push rod 5 is stretched to the limit position, the flat plate portion 411 is inclined toward the sink 3, and when the electric push rod 5 is retracted to the limit position, the inclined plate portion 412 is rotated to be separated from the sink 3.

[0035] In the above technical solution, when the electric push rod 5 is stretched to the limit position, the flat plate portion 411 is inclined toward the sink 3, and the workpiece to be quenched can be rolled into the basket portion 413 along the flat plate portion 411 or manually pushed into the basket portion 413 by using a tool.

[0036] After quenching, the inclined plate 412 is removed from the water surface by the retraction of the electric push rod 5 and held for a period of time, allowing the water on the inclined plate 412 to flow out into the water tank 3.

[0037] After the water has drained, the electric push rod 5 continues to retract, causing the inclined plate portion 412 to tilt outwards towards the water tank 3. The workpiece on the inclined plate portion 412 slides down to the flat plate portion 411, thus completing the quenching process.

[0038] See Figure 2 and Figure 5 As shown, at the bottom of the inclined plate portion 412, near the flat plate portion 411, there is an interception groove 4441, and drainage holes 4442 are evenly distributed at the bottom of the interception groove 4441.

[0039] The above technical solution can effectively intercept water, and the intercepted water is returned to the water tank 3 through the drain hole 4442.

[0040] See Figure 2 As shown, the inclined plate portion 412 has first drainage holes 4443 evenly distributed on its surface.
