Description

Technical Field

[0001] The utility model relates to the technical field of hot work die steel, and more specifically, the utility model relates to a rapid cooling device for hot work die steel. Background Art

[0002] Hot work die steel refers to alloy tool steel suitable for making dies for hot deformation processing of metals, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. Since hot work dies work under high temperature and high pressure conditions for a long time, it is required that the die material has high strength, hardness and thermal stability, especially high hot strength, thermal fatigue resistance, toughness and wear resistance. During the processing of hot work die steel, a cooling device is needed to cool it down. However, the existing cooling devices have low cooling quality and inconvenient operation, so they do not meet the existing requirements.

[0003] After retrieval, a Chinese patent with the publication number CN215162930U discloses a rapid cooling device for hot work die steel. This structure cools the die steel for the first time through the cooling water in the water cooling pool, cools the die steel for the second time through the cooling oil, and finally cools the die steel by air through the air cooling plate to achieve the third cooling of the die steel. Multi-stage cooling can ensure the cooling quality of the die steel and effectively avoid surface cracking and deformation of the die steel.

[0004] However, in actual use, since the internal shape of the hot work die steel is uneven after forming, after liquid cooling, liquid is likely to remain inside. And this structure moves the die into the water cooling pool for cooling through the die steel placement rack and then puts the die steel into the oil cooling pool for cooling. Because the liquid remaining on the surface of the die steel will enter the oil cooling pool along with the die, resulting in a mixing phenomenon between the oil and the liquid, which will reduce the oil cooling effect. And if the moisture inside the die steel is left to air dry, it takes a certain amount of time to wait, which will reduce the work efficiency. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the Figures 1-5 accompanying drawings, a rapid cooling device for hot work die steel includes a cooling pool 1. On one side inside the cooling pool 1, there is a water cooling pool 4, and on the other side of the cooling pool 1, there is an oil cooling pool 5. Outside the cooling pool 1, there are two mounting brackets 3. On the top of the two mounting brackets 3, three crossbars 12 are jointly provided. The surface of one of the crossbars 12 is threaded, and one end passes through the mounting bracket 3 and is connected to a first motor 13 and is connected to the output end of the first motor 13. A slider 11 is jointly sleeved outside the three crossbars 12. Four guiding telescopic rods 10 are connected to the bottom of the slider 11. An adjusting component is provided at the bottom of the slider 11. Four guiding telescopic rods 10 jointly set an installation seat 14 at the bottom. A stirring component is provided at the bottom of the installation seat 14. At the four corners of the bottom of the installation seat 14, a plurality of connecting rods 9 are connected. A plurality of connecting rods 9 jointly set a placement rack 8 at the bottom. A die steel placement rack 21 is slidably connected inside the placement rack 8. By driving the crossbar 12 with a thread on its surface to rotate by the first motor 13, the slider 11 can be driven to move parallel, so that the placement rack 8 can move parallel. The adjusting component can realize that the placement rack 8 drives the die steel on the surface of the die steel placement rack 21 to move vertically, and passes through the water cooling pool 4 and the oil cooling pool 5, improving the cooling quality.

[0023] As shown in the Figure 1 and 3 accompanying drawings, the adjusting component includes a connecting bracket 16 fixedly connected to the bottom of the slider 11. A receiving roller 20 is jointly rotatably connected to the surface of the connecting bracket 16. One end of the receiving roller 20 passes through the connecting bracket 16 and is connected to a kinetic energy motor 19 and is connected to the output end of the kinetic energy motor 19. The kinetic energy motor 19 is fixedly connected to the surface of the connecting bracket 16. A steel wire rope 18 is connected to the outside of the receiving roller 20. The bottom end of the steel wire rope 18 is connected to the surface of the installation seat 14. By driving the receiving roller 20 to rotate by the kinetic energy motor 19, the length of the released steel wire rope 18 can be adjusted to drive the die steel placement rack 21 to drive the die steel to move up and down, so that the die steel can be driven to move into the water cooling pool 4 or the oil cooling pool 5 for cooling treatment.

[0024] As shown in the Figures 3-5As shown in the figure, the stirring assembly includes a second motor 17 fixedly arranged on the surface of the mounting seat 14. The output end of the second motor 17 passes through the mounting seat 14 and is connected with a vertical rod 22. A cross-shaped stirring frame 23 is fixedly arranged at the bottom end of the vertical rod 22. The cross-shaped stirring frame 23 is located on the surface of the die steel placement rack 21. When the die steel contacts the liquid, the vertical rod 22 drives the cross-shaped stirring frame 23 to rotate the die steel to make it roll so that it can fully contact the cold water. At the same time, the heated water can be stirred by the cross-shaped stirring frame 23 and mixed evenly with the cold water accumulated at the bottom of the water cooling pool 4, which can improve the cooling effect. After the die steel is cooled by the cold water and separated from the cold water, the cross-shaped stirring frame 23 can rotate to quickly drain and dry the water inside the die steel.

[0025] As shown in the attached Figure 4 figure, an intercepting door 7 is slidably inserted on the surface of the placement rack 8. By inserting the intercepting door 7 inside the placement rack 8, the die steel placement rack 21 can be limited, and it can prevent the die steel from falling off the die steel placement rack 21 when the die steel is cooled.

[0026] As shown in the attached Figures 1-3 figure, two air cooling plates 15 are symmetrically connected to the top of the oil cooling pool 5. Air blowers 6 are arranged on the surfaces of the air cooling plates 15 and the mounting seat 14, which can accelerate the drying of the liquid on the surface of the die steel, effectively prevent the residual water inside the die steel from mixing with other liquids and reducing the cooling quality, and can effectively improve the practicability of the device.

[0027] As shown in the attached Figures 1-2 figure, the water cooling pool 4 and the oil cooling pool 5 are both provided with valve drain pipes 2 penetrating through the cooling pool 1, which can realize the function of discharging the liquid inside the water cooling pool 4 and the oil cooling pool 5.

[0028] The working principle of the present utility model: When the device is in use, first move the intercepting door 7 upward, then slide the die steel placement rack 21 filled with die steel into the bottom of the placement rack 8, and then reset the intercepting door 7, so as to limit the die steel placement rack 21 when the placement rack 8 moves, effectively preventing the die steel from rolling and falling during the movement. Then, drive the storage roller 20 to rotate by using the kinetic energy motor 19, so that the steel wire rope 18 is relaxed to adjust the vertical movement of the mounting seat 14 towards the water cooling pool 4. At the same time, the die steel can be driven to move into the water cooling pool 4 for cooling by water. At the same time, drive the output end of the second motor 17 to drive the vertical rod 22 to rotate, which can drive the cross-shaped stirring frame 23 to rotate, so that the die steel can fully contact the cold water through the stirring of the cross-shaped stirring frame 23 while being cooled. At the same time, the heated water can be driven to stir and quickly mix evenly with the cold water accumulated at the bottom of the water cooling pool 4, so as to achieve the function of improving the cooling effect;

[0029] After the mold steel is cooled by water cooling, the kinetic energy motor 19 drives the storage roller 20 to rotate in the reverse direction, which can move the placement rack 8 upward and at the same time drive the cross stirring frame 23 to rotate by the vertical rod 22, so that the mold steel can be quickly stirred to drain the moisture inside it. At the same time, by operating the blower 6 arranged on the bottom surface of the mounting seat 14, the moisture on the surface of the mold steel can be accelerated to dry, and the cooling speed and temperature can be reduced. Then, the first motor 13 drives the horizontal rod 12 with threads on its surface to rotate, which can drive the slider 11 to rotate, adjust the slider 11 to drive the placement rack 8 to move to the top of the oil cooling pool 5 and adjust the placement rack 8 to enter the oil cooling pool 5 to achieve oil cooling and temperature reduction. By using the same operation as when water cooling, the mold steel can be quickly cooled by oil cooling. After the oil cooling and temperature reduction are completed, by operating the blower 6 and the cross stirring frame 23, the air cooling effect can be achieved. Through multi-stage cooling, the cooling quality of the mold steel can be guaranteed, effectively avoiding surface cracking and deformation of the mold steel. After the temperature reduction is completed, by taking out the mold steel placement rack 21 from the placement rack 8, the mold steel can be quickly taken out, improving the working efficiency of the device.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
