Description

Technical Field

[0001] This application belongs to the field of steel production forming and cooling technology, and particularly relates to a cooling device for the production of magnetic steel. Background Technology

[0002] The most basic definition of a magnet is an AlNiCo alloy. Magnets are synthesized from several hard, strong metals, such as iron, aluminum, nickel, and cobalt; sometimes they are synthesized from copper, niobium, and tantalum. They are used to create ultra-hard permanent magnet alloys. Different metal compositions result in different magnetic properties and thus different applications. They are mainly used in various sensors, instruments, electronics, electromechanical systems, medical devices, educational materials, automobiles, aerospace, and military technology. AlNiCo magnets are the oldest type of magnet, often referred to as natural magnets. Although they are the oldest, their excellent adaptability to high temperatures makes them one of the most important magnets today. AlNiCo can operate normally at temperatures above 500℃, which is its greatest characteristic. Additionally, its corrosion resistance is stronger than other magnets. To meet market demands, efficient production equipment is used for manufacturing, and among this equipment, cooling devices are indispensable.

[0003] Existing cooling devices often immerse the magnets directly in water for cooling, which can easily cause thermal stress cracks due to sudden cooling. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a cooling device for the production of magnetic steel, which can provide stepped cooling to avoid thermal stress cracks caused by sudden cooling, and hydraulic slow immersion to ensure uniform stress release and improve the structural stability of the magnetic steel.

[0005] This application provides a cooling device for the production of magnetic steel, including a workbench, and further comprising: Cooling components; The cooling assembly includes a rotating shaft, a support frame, a hydraulic telescopic rod, a mounting frame, a mounting component, a first water-cooled tank, and a second water-cooled tank. Both the first and second water-cooled tanks are placed on a workbench. The rotating shaft is mounted on the workbench and positioned between the first and second water-cooled tanks. The support frame is mounted on the drive shaft. Several hydraulic telescopic rods are mounted on the support frame. The mounting frame is mounted at the output end of the hydraulic telescopic rods. The mounting component is placed on the mounting frame.

[0006] The system is vertically installed between two water-cooled tanks via a rotating shaft. A support frame is fixed to the top of the rotating shaft, and multiple hydraulic telescopic rods are distributed along the support frame. Their output ends are connected downwards to the mounting frame, which then supports the mounting assembly. The working principle is as follows: After the magnetic steel casting is loaded into the mounting assembly, the hydraulic telescopic rods slowly descend into the first water-cooled tank for medium-temperature pre-cooling (60–70℃) to eliminate internal thermal stress. After resetting the hydraulic telescopic rods, the rotating shaft is driven to rotate horizontally 180°. The hydraulic telescopic rods and the rotating shaft are driven by an external drive device to transfer the casting to the second water-cooled tank. The hydraulic telescopic rods descend again to achieve thorough cooling at a low temperature (25–40℃). This stepped cooling avoids thermal stress cracks caused by sudden cooling. Slow hydraulic immersion ensures uniform stress release and improves the stability of the magnetic steel structure.

[0007] Furthermore, the placement component includes: Installation basket, which is placed on a mounting rack; A hoisting handle is mounted on the installation basket.

[0008] The mounting assembly consists of an installation basket and a hoisting handle. The installation basket is placed directly on the top plane of the mounting frame via a bracket. The hoisting handle is welded to the two sides of the installation basket. The magnetic steel castings are placed in the perforated installation basket, allowing the coolant to flow freely. The hoisting handle facilitates the transfer of the fully loaded installation basket by the crane, improving loading and unloading efficiency. At the same time, the open structure ensures that the cooling medium fully contacts the surface of the castings.

[0009] Furthermore, the cooling assembly also includes: Cooling tank, which is mounted on the workbench; A refrigeration unit, comprising a condenser, a compressor, an expansion valve, and an evaporator, is integrated within a cooling tank; A first submersible pump, which is placed inside a cooling tank; The water inlet pipe is installed on the first submersible pump at one end and on the second water-cooling tank at the other end, and is connected to the second water-cooling tank.

[0010] The cooling system is equipped with a cooling tank and an integrated refrigeration unit (including a condenser, compressor, expansion valve, and evaporator). The refrigeration unit is built into the cooling tank cavity. The first submersible pump is submerged at the bottom of the cooling tank and connected to the second water-cooled tank through a water inlet pipe. The refrigeration unit continuously cools the water in the cooling tank to a low temperature. The first submersible pump pumps the cold water into the second water-cooled tank to ensure a constant low temperature environment in the second water-cooled tank and improve heat exchange efficiency.

[0011] Furthermore, the cooling assembly also includes: A second submersible pump, which is placed inside a cooling tank; The first drain pipe is installed on the second submersible pump and extends out of the cooling tank; A debris removal component is connected and installed on the first drain pipe; The second drain pipe has one end connected to the impurity removal component and the other end installed on the second water cooling tank.

[0012] By adding a second submersible pump, a cleaning component, and dual drain pipes to the water circulation system, the second submersible pump is placed inside the cooling tank. Its outlet is connected to the first drain pipe that extends out of the tank. The first drain pipe is connected to the cleaning component and then to the second water-cooled tank via the second drain pipe. The overflow high-temperature water from the second water-cooled tank is discharged through the first drain pipe, purified by the cleaning component, and then pumped back to the cooling tank by the second submersible pump for recooling, thus realizing a closed-loop circulation of cooling water and reducing water consumption.

[0013] Furthermore, the impurity removal component includes: A receiving tube, one end of which is connected to and installed on a first drain pipe, and the other end of which is connected to and installed on a second drain pipe; A filter screen, which is installed inside a receiving tube.

[0014] The impurity removal component consists of a cylindrical receiving tube and a built-in filter screen. The flanges at both ends of the receiving tube are connected to the first drain pipe and the second drain pipe, respectively. The filter screen is installed vertically inside the receiving tube. When the circulating water flows through the receiving tube, suspended particles are trapped by the filter screen and deposited at the bottom of the tube. The detachable tube design makes it easy to clean impurities regularly and reduces the risk of clogging.

[0015] Furthermore, the cooling assembly also includes: A fan, wherein several fans are mounted on a support frame.

[0016] Multiple fans are installed on the side wall of the support frame, with the air outlets facing the lifting path of the installation basket. When the hydraulic telescopic rod lifts the installation basket out of the water-cooled tank, the fans start to generate high-speed airflow to blow away residual water droplets on the surface of the casting, forcibly drying and shortening the draining time, accelerating the entry into the next process, and reducing surface water stains.

[0017] The beneficial effects of this application are: 1. Stepped cooling avoids thermal stress cracks caused by sudden cooling, and slow hydraulic immersion ensures uniform stress release and improves the stability of the magnetic steel structure. 2. The magnetic steel castings are placed in a perforated installation basket, allowing the coolant to circulate freely; the lifting handles facilitate the transfer of the fully loaded installation basket by the crane, improving loading and unloading efficiency, while the open structure ensures that the cooling medium fully contacts the surface of the castings; 3. The refrigeration unit continuously cools the water in the cooling tank to a low temperature, and the first submersible pump pumps the cold water into the second water-cooled tank to ensure a constant low temperature environment in the second water-cooled tank and improve heat exchange efficiency.
