[0002] Quenching is a metal heat treatment process designed to change the physical properties of a metal by rapid cooling, thereby increasing its hardness, strength and wear resistance. The process usually involves heating the metal above a critical temperature, holding it for a period of time, and then rapidly cooling it to introduce specific physical changes. Quenching can be applied to a variety of metals, including steel, as well as some special alloys such as stainless steel and permanent magnetic steel.

[0003] For example, the patent document with the announcement number CN 219547012 U discloses a quenching device, including a shell, a lifting assembly is arranged on one side of the top of the shell, a cooler is arranged on the side of the shell away from the shell, two connecting pipes of the cooler are both installed with sealing blocks near the shell, the two sealing blocks pass through the shell, and a coil is arranged between the two connecting pipes of the cooler in the shell. The device has high practical value and is worth promoting.

[0004] However, in actual use, this structure can only use static cooling and quenching operations with quenching liquid. When the quenched metal parts are thicker, the equipment cannot increase the quenching depth and cannot perform deep cold quenching treatment operations on the metal surface. At the same time, due to the limitations of its own structure, the equipment cannot perform continuous quenching operations and cannot meet daily use needs. Therefore, it is urgent to design a deep cold treatment device that can increase the quenching depth to solve the above problems. Utility Model Content

When the quenched metal part is in a thicker shape, the equipment cannot increase the quenching depth and cannot perform deep-cold quenching treatment operation on the metal surface. At the same time, due to the limitation of its own structure, the equipment cannot perform continuous quenching operation and cannot meet the needs of daily use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cryogenic treatment device for improving quenching depth, comprising a quenching hood, wherein lifting push rods are arranged on both sides of the surface of the quenching hood, the top of the quenching hood is movably connected to a lifting top cover, the bottom end of the lifting top cover is fixedly connected to a quenching bracket, and the bottom end of the quenching bracket is movably connected to a positioning base;

[0007] The first liquid storage seat is fixedly connected to the bottom end of the quenching cover, the bottom end of the first liquid storage seat is fixedly connected to the heat insulation seat, and the bottom end of the heat insulation seat is fixedly connected to the second liquid storage seat.

[0008] Preferably, a refrigeration liner is disposed inside the first liquid storage seat and the second liquid storage seat, and a refrigeration unit is disposed on the inner bottom wall of the first liquid storage seat and the second liquid storage seat.

[0009] Preferably, liquid control pumps are staggeredly arranged at both ends of the side surfaces of the first liquid storage seat and the heat insulation seat, and a filter element is arranged on the inner wall of the liquid control pump.

[0010] Preferably, the four sides of the quenching cover are fixedly connected with an infusion side frame, and the inner wall of the infusion side frame is provided with an infusion grid.

[0011] Preferably, lifting slide grooves are provided on both sides of the inner wall of the quenching cover, and lifting slide blocks are fixedly connected to both sides of the top of the quenching bracket.

[0012] Preferably, flow holes are arranged at the upper and lower ends of the interior of the quenching bracket, and vortex fans are arranged inside the lifting top cover and the positioning base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The deep cryogenic treatment device for improving quenching depth can make the device perform deep cryogenic treatment for improving quenching depth by arranging a quenching cover, a lifting push rod, a lifting top cover, a quenching bracket, a positioning base, an infusion side frame, an infusion grid, a lifting slide, a lifting slider, a flow hole and a vortex fan. In actual use, the staff first puts the metal parts to be quenched into the interior of the quenching bracket, and then starts the lifting push rods on both sides of the surface of the quenching cover to make them pass through the lifting slide and the lifting slider, so that the lifting top cover and the quenching bracket are moved to the interior of the quenching cover. Perform the lifting and adjusting operation, and then dock the bottom end of the quenching bracket with the positioning base. At this time, the infusion side frames and infusion grids on the four sides of the quenching cover can be used to add the quenching liquid that is suitable for the quenching bracket. At the same time, the vortex fans inside the lifting top covers at the upper and lower ends of the quenching bracket are started synchronously, and a flow structure of quenching liquid vortex is formed at the flow holes at the upper and lower ends of the quenching bracket, ensuring that the quenching can also flow continuously on the surface of the metal parts, thereby increasing the quenching depth and achieving the deep quenching treatment of the metal parts, which reflects the practicality of the equipment design.

[0015] The cryogenic treatment device for improving the quenching depth further improves the overall use effect of the equipment by providing a first liquid storage seat, a heat insulation seat, a second liquid storage seat, a refrigeration liner, a refrigeration unit, a liquid control pump and a filter element.
