[0041] In order to change the medium flow state in the quenching device, thereby enhancing the adaptability of the quenching device to the parts, so that the quenching device can quench parts of different shapes, such as Figure 1-Figure 5 As shown, the present invention provides a quenching device. The quenching device comprises a first trough body 1, a second trough body 2, a plurality of first drive pipeline assemblies 3 and a plurality of second drive pipeline assemblies 4, wherein the first trough body 1 is arranged with an opening facing upward, and can contain a quenching medium; the second trough body 2 is a cylindrical structure with openings at both ends, and is arranged in the first trough body 1, and the bottom end of the second trough body 2 is arranged at intervals from the bottom of the first trough body 1, and the top end of the second trough body 2 is lower than the top end of the first trough body 1, and the parts are quenched in the second trough body 2; a plurality of first drive pipeline assemblies 3 are arranged between the first trough body 1 and the second trough body 2 at intervals around the circumference of the second trough body 2, and are connected to the bottom end of the second trough body 2, and are used to drive the quenching medium in the second trough body 2 to move upward in the vertical direction; a plurality of second drive pipeline assemblies 4 are arranged in the first trough body 1 at intervals around the circumference of the second trough body 2, and are connected to the side wall of the second trough body 2, and are used to drive the quenching medium in the second trough body 2 to move along the circumference of the second trough body 2.

[0042] Specifically, at least three groups of the first drive pipeline assembly 3 and the second drive pipeline assembly 4 are provided. In this embodiment, six groups of the first drive pipeline assembly 3 are provided, and four groups of the second drive pipeline assembly 4 are provided. Of course, the number of the first drive pipeline assembly 3 and the second drive pipeline assembly 4 can be set according to actual needs, and no excessive restrictions are made here.

[0043] A second trough body 2 is arranged in the first trough body 1, and a quenching medium is placed in the first trough body 1. Since the second trough body 2 is lower than the first trough body 1, the second trough body 2 is also filled with the quenching medium. A plurality of first driving pipeline assemblies 3 are arranged between the first trough body 1 and the second trough body 2 along the circumference of the second trough body 2 to drive the quenching medium in the second trough body 2 to move upward in the vertical direction; a plurality of second driving pipeline assemblies 4 connected to the side wall of the second trough body 2 are arranged in the first trough body 1 along the circumference of the second trough body 2 to drive the quenching medium in the second trough body 2 to move along the circumference of the second trough body 2, thereby changing the flow state of the quenching medium in the second trough body 2, reducing the shape requirements of the parts that have been quenched in the second trough body 2, and enhancing the adaptability of the quenching device to the parts.

[0044] Furthermore, the first driving pipeline assembly 3 includes: a first pipeline assembly and a first propeller 35; wherein, one end of the first pipeline assembly is connected to the bottom end of the second tank body 2; the first propeller 35 is rotatably arranged at the top end of the first pipeline assembly, and the first propeller 35 can discharge the quenching medium in the first tank body 1 into the second tank body 2 through the first pipeline assembly, so as to drive the quenching medium in the second tank body 2 to move upward in the vertical direction.

[0045] Specifically, the first pipeline assembly includes: a first vertical pipe 31, a first horizontal pipe 32 and a first folded pipe 33, wherein a first propeller 35 is provided at the top of the first vertical pipe 31; one end of the first horizontal pipe 32 is connected to an end of the first vertical pipe 31 away from the first propeller 35; one end of the first folded pipe 33 penetrates into the second tank body 2 at the bottom end of the second tank body 2, and the other end is connected to the first horizontal pipe 32, and the first folded pipe 33 and the first horizontal pipe 32 are arranged at an obtuse angle. The quenching medium is discharged from the bottom of the second tank body 2 through the first vertical pipe 31, the first horizontal pipe 32 and the first folded pipe 33 by the first propeller 35, so that the quenching medium in the second tank body 2 moves upward in the vertical direction, so that the parts located in the quenching medium can be in close contact with the quenching medium in the vertical direction, thereby ensuring the performance of the parts after quenching.

[0046] Furthermore, the first folded tube 33 is rotatably connected to the first horizontal tube 32, and the angle between the first folded tube 33 and the first horizontal tube 32 can be adjusted between 120° and 150°. By adjusting the angle between the first folded tube 33 and the first horizontal tube 32, the incident angle of the quenching medium entering the bottom of the second tank body 2 through the first folded tube 33 can be changed, thereby achieving the purpose of adjusting the flow speed of the quenching medium in the second tank body 2 along the vertical direction, and being able to better adapt to the quenching requirements of parts of different shapes.

[0047] Furthermore, an arc-shaped flow dividing piece 34 is fixedly provided at one end of the first folded tube 33 away from the first horizontal tube 32. When the angle between the first folded tube 33 and the first horizontal tube 32 is 150°, the arc-shaped flow dividing pieces 34 provided on the first folded tubes 33 form a ring. By providing the arc-shaped flow dividing pieces 34, the flow dividing pieces at the first folded tube 33 divide the outlet of the first folded tube 33 according to a certain ratio, so that the quenching medium flowing out of the first pipeline assembly is evenly distributed in the second tank 2.

[0048] Furthermore, the second driving pipeline assembly 4 includes: a second pipeline assembly and a second propeller 43, wherein the second pipeline assembly is arranged in the first tank body 1 and is connected to the side wall of the second tank body 2; the second propeller 43 is rotatably arranged on the second pipeline assembly, and can discharge the quenching medium in the first tank body 1 into the second tank body 2 through the second pipeline assembly, so as to drive the quenching medium in the second tank body 2 to move circumferentially along the second tank body 2.

[0049] Specifically, the second pipeline assembly includes: a second vertical pipe 41 and a plurality of second horizontal pipes 42, wherein the second vertical pipe 41 is arranged in the first tank body 1 along the vertical direction, and a second propeller 43 is arranged at the top thereof; and the plurality of second horizontal pipes 42 are arranged at intervals along the height direction of the second vertical pipe 41, and one end is connected to the second vertical pipe 41, and the other end is connected to the second tank body 2. The quenching medium in the first tank body 1 is discharged into the second tank body 2 through the plurality of second horizontal pipes 42 by the second propeller 43, thereby pushing the quenching medium in the second tank body 2 to rotate along the circumferential direction of the second tank body 2. In this embodiment, at least three second horizontal pipes 42 are arranged.

[0050] Furthermore, a pulley is provided at the lower end of the second vertical pipe 41, and the second vertical pipe 41 can slide through the pulley, thereby adjusting the flow direction of the quenching medium in the second horizontal pipe 42 when it flows into the second tank body 2. Through the above arrangement, the flow direction of the quenching medium in the second horizontal pipe 42 when it flows into the second tank body 2 can be adjusted according to actual needs, so as to achieve the purpose of changing the circumferential flow speed of the quenching medium along the second tank body 2, thereby meeting the quenching needs of different parts.

[0051] Furthermore, if Figure 5As shown, a baffle 44 is provided on the inner wall of the second horizontal tube 42 at one end of the second horizontal tube 42 facing the second tank body 2, and the baffle 44 is an annular structure with a bell mouth provided thereon. The baffle 44 reduces the flow area, thereby controlling the flow rate of the quenching medium flowing through the second horizontal tube 42. Specifically, since the flow rate of the quenching medium in the second horizontal tube 42 closest to the top of the second vertical tube 41 is greater than the flow rate of the quenching medium in other second horizontal tubes 42, in order to ensure that the flow rate and direction of the quenching medium in the second horizontal tube 42 are the same, optionally, the size of the baffle 44 in the plurality of second horizontal tubes 42 provided on the same second vertical tube 41 is gradually reduced in the vertical downward direction. The purpose of changing the flow rate and direction of the quenching medium is achieved by changing the size of the baffle 44.
