Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to a heat treatment cooling device. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which materials are heated, held at temperature and cooled in a solid state to obtain the desired structure and properties. In the process of progressing from the Stone Age to the Bronze Age and Iron Age, the role of heat treatment has gradually been recognized. Quenching is a heat treatment process in which workpieces need to be quenched for rapid cooling after heat treatment. However, the current quenching process generally involves immersing the workpiece directly in water.

[0003] However, due to the extremely high temperature of the workpiece, a vapor film easily forms on the surface of the workpiece, affecting the cooling effect. Therefore, solid particles are added to the water to help clean the surface of the workpiece, destroy the vapor film, increase the cooling rate, and prevent the occurrence of quenching spots. However, the existing workpiece is placed directly in water, and the water has poor fluidity, resulting in poor destruction of the vapor film on the surface of the workpiece. Therefore, how to solve this problem needs to be considered. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat treatment cooling device. The use of this cooling device can effectively ensure the continuous cooling effect of the cooling liquid. In addition, it can promote liquid flow, thereby improving the vapor film breaking effect and enhancing the overall cooling speed and quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat treatment cooling device includes a housing, an L-shaped plate fixedly connected to the upper end of the housing, a hydraulic telescopic rod installed at the lower end of the horizontal portion of the L-shaped plate, a horizontal plate fixedly connected to the telescopic end of the hydraulic telescopic rod, two connecting rods symmetrically fixedly connected to the lower end of the horizontal plate, and a placement plate fixedly connected to the lower ends of the two connecting rods; a liquid flow mechanism including a high-pressure air pump installed on the right side of the housing, a rotating tube rotatably connected to the inner bottom of the housing, the rotating tube being a tube with a sealed upper end and an open lower end, U-shaped connecting pipes connected to both sides of the rotating tube, the lower end of the rotating tube extending to the outside, a high-pressure air pump installed on the right side of the housing, a vortex tube connected to the outlet end of the high-pressure air pump, the cold air end of the vortex tube being connected to the lower end of the rotating tube through a rotary joint; and a rotation mechanism for driving the rotating tube to rotate.

[0007] Preferably, a plurality of support columns are installed at the lower end of the box body.

[0008] Preferably, a one-way valve is installed in both of the U-shaped connecting pipes.

[0009] Preferably, the hydraulic telescopic rod is a multi-section telescopic rod.

[0010] Preferably, the rotating mechanism includes a motor installed at the lower end of the housing, and pulleys are installed on the outer side of the lower end of the rotating tube and on the output shaft of the motor. The two pulleys are connected by a transmission belt.

[0011] Preferably, a hollow ring is provided inside the box, and the other ends of the two U-shaped connecting pipes are connected to the hollow ring. Multiple exhaust holes are provided on the inner side of the hollow ring.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] Equipped with a high-pressure air pump and a vortex tube, in actual use, the gas enters the water in the form of bubbles, which promotes water flow and causes the water to carry microparticles, breaking down the vapor film on the surface of the workpiece. Combined with the rotating mechanism, the vapor film is broken down even more effectively. In addition, due to the use of the vortex tube, the incoming airflow is a low-temperature airflow, which can cool the water and ensure its continuous cooling effect, greatly improving the actual cooling efficiency and quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A heat treatment cooling device includes a box body 1. Multiple support columns 2 are installed at the lower end of the box body 1. An L-shaped plate 5 is fixedly connected to the upper end of the box body 1. A hydraulic telescopic rod 6 is installed at the lower end of the horizontal part of the L-shaped plate 5. The hydraulic telescopic rod 6 is a multi-section telescopic rod. A horizontal plate 4 is fixedly connected to the telescopic end of the hydraulic telescopic rod 6. Two connecting rods 7 are symmetrically fixedly connected to the lower end of the horizontal plate 4. A placement plate 8 is fixedly connected to the lower end of the two connecting rods 7.

[0020] The system also includes a liquid flow mechanism, which includes a high-pressure air pump 3 installed on the right side of the housing 1. A rotating pipe 13 is rotatably connected to the bottom of the housing 1. The rotating pipe 13 is a pipe with a sealed upper end and an open lower end. Both sides of the rotating pipe 13 are connected to U-shaped connecting pipes 16. The lower end of the rotating pipe 13 extends to the outside and a rotating sealing gasket is installed at the point where it penetrates the housing 1 to ensure rotational sealing. The high-pressure air pump 3 is installed on the right side of the housing 1. The outlet end of the high-pressure air pump 3 is connected to a vortex pipe 15. The vortex pipe 15 is a prior art technology. When a high-pressure airflow is introduced, one end of the vortex pipe 15 generates hot air and the other end generates cold air. The cold air end of the vortex pipe 15 is connected to the lower end of the rotating pipe 13 through a rotating joint 14.

[0021] Among them, one-way valves are installed in both U-shaped connecting pipes 16, and the flow direction of the one-way valves is that the rotating pipe 13 enters the hollow ring 9 in one direction;

[0022] It also includes a rotating mechanism for driving the rotating tube 13 to rotate. The rotating mechanism includes a motor 11 installed at the lower end of the housing 1. Pulleys 12 are installed on the outer side of the lower part of the rotating tube 13 and on the output shaft of the motor 11. The two pulleys 12 are connected by a transmission belt. A hollow ring 9 is provided inside the housing 1. The other ends of the two U-shaped connecting pipes 16 are connected to the hollow ring 9. Multiple exhaust holes 10 are opened on the inner side of the hollow ring 9.

[0023] In this utility model, when in use, the box 1 is filled with water containing microparticles. The worker places the heat-treated workpiece on the placement plate 8, and then starts the hydraulic telescopic rod 6 to grow, so that the workpiece is submerged in the water for cooling.

[0024] During this process, the high-pressure air pump 3 is started. After the high-pressure airflow passes through the vortex tube 15, the low-temperature airflow enters the U-shaped connecting tube 16 through the vertical rotating tube 13, and then enters the hollow ring 9. Finally, it is discharged from the exhaust hole 10. The gas enters the water in the form of bubbles, which promotes the flow of the water and causes the water to carry microparticles to flow and destroy the vapor film on the surface of the workpiece. At the same time, the motor 11 is started. Through the transmission of the pulley 12 and the transmission belt, the rotating tube 13 drives the U-shaped connecting tube 16 and the hollow ring 9 to rotate, so that the water flow driven by the airflow generated by the exhaust hole 10 can contact the workpiece more evenly. At the same time, the rotation of the U-shaped connecting tube 16 will lift the microparticles that have settled at the bottom, so as to avoid the microparticles settling and affecting the destruction effect of the vapor film.

[0025] It should be noted that since it is used through the vortex tube 15, the incoming airflow is a low-temperature airflow, which can cool the water and ensure its continuous cooling effect.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
