Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, and in particular to a quenching heat treatment device for metal material processing. Background Technology

[0002] Quenching is a key process in the heat treatment of metallic materials. Its main purpose is to rapidly cool and alter the internal microstructure of the metal, thereby significantly improving the material's hardness and strength. Metal heated to its austenitizing temperature is quickly immersed in a quenching medium, causing the supercooled austenite to transform into high-hardness structures such as martensite or bainite, meeting the requirements of mechanical parts in terms of wear resistance, fatigue strength, and service life. Simultaneously, quenching can be combined with subsequent tempering treatment to effectively adjust the material's toughness and plasticity, achieving a reasonable balance between hardness and impact resistance.

[0003] In existing technologies, during the quenching process of metallic materials, the high temperature of the workpiece causes violent vaporization and thermal shock of the quenching medium, often resulting in a large amount of overflow and splashing of the medium. This not only creates a slippery working environment and poses safety hazards such as burns, but also easily leads to rapid loss of cooling medium, resulting in serious waste of water resources. At the same time, the splashing high-temperature droplets may damage equipment or endanger operators, affecting production safety and efficiency. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides an embodiment of a quenching heat treatment device for metal material processing, comprising a supporting tank 1, a quenching tank 2 disposed within the supporting tank 1, a cooling component 4 disposed on one side of the supporting tank 1, a buffer baffle 5 disposed on the quenching tank 2 to mitigate rapid water overflow, a circulation component 3 disposed within the supporting tank 1, the circulation component 3 comprising a baffle 31, the baffle 31 forming an isolation space and a receiving space within the supporting tank 1, the receiving space being used to receive water overflowing from the quenching tank 2, a spiral tube 34 connected to the baffle 31, allowing water from the receiving space to enter the isolation space through the spiral tube 34, a first pump 33 installed within the isolation space, the first pump 33 being used to pump water from the isolation space into the quenching tank 2. By setting up the circulation component 3, automatic recycling and reuse of quenching water is achieved, effectively avoiding water waste. The containment space collects overflow water, preventing water accumulation and splashing on site; the design of the spiral tube 34 extends the water flow path, which is conducive to the natural heat dissipation of water during the flow process and extends the service life of the first pump body 33; the isolation space works in conjunction with the first pump body 33 to realize the return of overflowing water and ensure the stability of system operation.

[0019] Please see Figure 1-5 A further solution based on this embodiment is as follows: the buffer stop 5 includes a connecting plate 51 welded to the quenching tank body 2, and a U-shaped plate 52 integrally formed on the connecting plate 51. The U-shaped plate 52 is integrally formed with the connecting plate 51 and welded to the quenching tank body 2, resulting in a robust structure that effectively enhances the overall strength and durability of the buffer stop 5. This design can mitigate the impact of water flow when the workpiece is immersed in the quenching liquid, reducing the risk of water gushing out instantly.

[0020] Please see Figure 2-4 A further solution based on this embodiment is as follows: The buffer baffle 5 is provided with a water passage hole 53 penetrating the connecting plate 51 and the U-shaped plate 52. Water in the quenching tank 2 can enter the U-shaped groove of the U-shaped plate 52 through the water passage hole 53 of the connecting plate 51, and water in the U-shaped groove can fall into the receiving space through the water passage hole 53 of the U-shaped plate 52. The water passage hole 53 allows water to flow slowly from the quenching tank 2 to the U-shaped groove via overflow, and then fall into the receiving space, significantly reducing the water flow velocity and impact force, further suppressing water splashing during quenching. This achieves a stable drainage effect as much as possible.

[0021] Please see Figure 1-5 A further embodiment of this solution involves connecting the outlet of the first pump body 33 to one end of the fifth water pipe 32, with the other end of the fifth water pipe 32 positioned above the quenching tank body 2. Water within the isolation space can be discharged into the quenching tank body 2 from the other end of the fifth water pipe 32. Water is then recycled by re-injecting the return water into the quenching tank body 2 from above through the fifth water pipe 32.

[0022] Please see Figure 4-5 A further solution based on this embodiment is as follows: A guide cylinder 35 is provided in the isolation space, and a through-hole 37 is provided on the guide cylinder 35. A float 36 is inserted inside the guide cylinder 35. A support 381 is provided on the supporting pool 1, and a lever 382 is rotatably connected to the support 381. An mounting plate 383 is provided on the outer wall of the supporting pool 1, and a button 384 is installed on the mounting plate 383. When the float 36 moves upward, it can drive one end of the lever 382 to move upward and drive the other end of the lever 382 to move downward. The other end of the lever 382 can press the button 384. When the button 384 is pressed, the first pump 33 is powered on and operates. The guide cylinder 35 provides stable lifting guidance for the float 36, ensuring that its movement trajectory is vertical and improving the accuracy of liquid level detection. When the water level in the isolation space rises, the float 36 floats up and automatically triggers the button 384 through the lever 382 mechanism, realizing the start of the first pump 33. This reduces manual control, has a simple structure, reliable response, and has good automation control performance and energy-saving effect.

[0023] Please see Figure 2-4A further embodiment of this solution is as follows: the cooling assembly 4 includes a cooling tank 44. A first water pipe 42 and a fourth water pipe 6 are connected in series on the outer walls of the cooling tank 44 and the supporting tank 1. A second pump body 423 is connected in series on the first water pipe 42. The first water pipe 42 is used to guide water from the supporting tank 1 into the cooling tank 44. The cooling tank 44 is equipped with a cooling section. Driven by the second pump body 423, high-temperature water is forcibly transported from the supporting tank 1 to the cooling tank 44, forming an active circulating cooling loop, significantly improving cooling efficiency. The first water pipe 42 and the fourth water pipe 6 form a closed-loop circulation channel, and the second pump body 423 is of high-temperature resistant type.

[0024] Please see Figure 2-4 A further embodiment of this solution is as follows: the cooling section includes a second water pipe 41 connected to the first water pipe 42, and a plurality of third water pipes 411 are provided on the second water pipe 41. The third water pipes 411 are used to accelerate the cooling speed. The multiple third water pipes 411 are distributed on the second water pipe 41, which significantly increases the heat exchange area and promotes rapid heat dissipation. The heat dissipation method of utilizing the temperature of the water inside the cooling pool 44 can be used in areas where the circulation volume of the cooling pool 44 and the supporting pool 1 is small and the area is cold.

[0025] For another embodiment of the cooling unit, please refer to [link / reference]. Figure 6 A further embodiment of this solution includes: a cooling section comprising a heat-absorbing plate 421 fitted to the inner wall of the cooling pool body 44, a heat dissipation plate 422 corresponding to the heat-absorbing plate 421 on the outer wall of the cooling pool body 44, and a cooling fan 43 installed on the cooling pool body 44 for blowing air onto the heat dissipation plate 422. The heat-absorbing plate 421 and the heat dissipation plate 422 form a thermally conductive bridge structure, which can efficiently conduct heat from inside the cooling pool body 44 to the outside, and, in conjunction with the forced air cooling by the cooling fan 43, achieve rapid heat dissipation.

[0026] Working Principle: Metal workpieces are immersed in the quenching liquid within the quenching tank 2 for rapid cooling. Due to the intense heat exchange occurring the moment the workpiece enters the liquid, the liquid level rises sharply, posing a significant risk of overflow. At this time, the buffer baffle 5 above the quenching tank 2, through its U-shaped plate 52 and connecting plate 51 forming a stepped structure, physically blocks the water flow. Simultaneously, the quenching liquid flows through the through-hole 53 from the connecting plate 51 into the U-shaped groove, and then drips back into the receiving space through the through-hole 53 on the U-shaped plate 52, achieving multi-stage buffer overflow, effectively slowing the water flow and suppressing splashing. The overflowing water collects in the receiving space and then slowly flows into the isolation space through the spiral tube 34. The coiled structure of the spiral tube 34 extends the water flow path, facilitating natural heat dissipation and reducing the return water temperature. As the water level in the isolation space gradually rises, the guide... The float 36 inside the cylinder 35 rises vertically with the liquid level, and through mechanical linkage, it drives the lever 382 to rotate, causing one end of the lever to press down on the button 384 mounted on the mounting plate 383, thereby automatically connecting the power supply to the first pump body 33. After the first pump body 33 starts, it pumps the water in the isolation space back to the top of the quenching tank 2 through the fifth water pipe 32, realizing the closed-loop recycling of the quenching liquid. At the same time, some high-temperature water is pumped through the first water pipe 42 to the cooling tank 44 of the cooling assembly 4 for cooling treatment via the second pump body 423. The cooling method can be selected to increase the heat exchange area through the second water pipe 41 and its branch third water pipe 411 to achieve natural heat dissipation, or to conduct heat to the external heat dissipation plate 422 through the heat absorption plate 421 and be forced by the cooling fan 43 to accelerate heat dissipation. The cooled water is returned to the system for recycling through the fourth water pipe 6. The second pump body 423, the first pump 33, and the button 384 are all existing technologies, and the corresponding pipeline connection methods and circuit wiring methods are known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
