Description

Technical Field

[0001] This utility model relates to the field of non-magnetic steel forging technology, and in particular to a device for eliminating annular defects in non-magnetic steel forging. Background Technology

[0002] Eliminating annular defects in non-magnetic forged round steel is mainly achieved by optimizing the forging process, which often involves the coordinated operation of heating equipment, forging equipment, and cooling equipment.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing cooling structures for eliminating non-magnetic steel forgings generally rely on water for cooling, lacking a structure for rapidly cooling the water. This causes the temperature of the cooling water to rise continuously during operation. As the water temperature increases, the temperature difference between the water and the non-magnetic steel forging decreases, significantly reducing heat exchange efficiency and thus lowering the cooling efficiency of the non-magnetic steel forging.

[0004] To address this, a device for eliminating annular defects in non-magnetic forged round steel is proposed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The heat-conducting plate in the cooling mechanism of this application is in direct contact with the water in the cooling tank, which can quickly transfer the heat in the water to the outside of the tank, increasing the heat dissipation area. The semiconductor refrigeration plate can cool down the surrounding air temperature. The electric fan blows the cold air to the water surface, accelerating heat exchange and making the cooling water cool down quickly. The servo motor drives the stirring rod to rotate, stirring the water in the cooling tank to avoid local water temperature being too high, ensuring uniform water temperature, so that the non-magnetic steel forging round is heated evenly during the cooling process, reducing internal stress and defects caused by uneven cooling.

[0017] 2. The circulating pump in the circulating mechanism of this application draws water from the cooling tank through the water extraction pipe, and sprays it out from the nozzle through the distribution pipe and connecting pipe, realizing the recycling of cooling water. This avoids the problem of reduced cooling effect due to increased cooling water temperature, and continuously provides low-temperature cooling water for non-magnetic steel forging rounds. By recycling the cooling water, water waste is reduced and production costs are lowered. At the same time, the continuous and stable cooling effect helps to improve the production quality and efficiency of non-magnetic steel forging rounds and reduce the occurrence of annular defects during flaw detection.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A device for eliminating annular defects in non-magnetic steel forging rounds includes a cooling box 1, a partition 2 welded to the inner side of the cooling box 1, a water leakage hole 3 at the bottom of the partition 2, a cooling mechanism 4 fixedly connected to the bottom of the right side of the inner side of the cooling box 1, a circulation mechanism 5 fixedly connected to the rear side of the cooling box 1, a PLC controller 6 installed on the front surface of the cooling box 1, a temperature sensor 7 installed on the right side of the cooling box 1, the detection end of the temperature sensor 7 on the left side penetrating and extending to the inner side of the cooling box 1, and a placement box 8 fixedly connected to the top of the inner left side of the cooling box 1.

[0027] The cooling mechanism 4 includes several heat-conducting plates 41, mounting plates 42, servo motors 43, stirring rods 44, cooling shells 45, several air vents 46, several semiconductor cooling plates 47, mounting slots 48, and electric fans 49. The heat-conducting plates 41 are fixedly connected to the bottom of the inner right side of the cooling box 1, and the rear side of the heat-conducting plates 41 extends through and to the outer side of the cooling box 1. The mounting plates 42 are welded to the right side of the top of the cooling box 1.

[0028] In this embodiment: The cooling tank 1 supports and limits the partition 2, cooling mechanism 4, circulation mechanism 5, PLC controller 6, temperature sensor 7, and placement box 8. The partition 2 divides the interior of the cooling tank 1 into different areas, guiding the water flow path and creating a specific flow trajectory within the cooling tank 1, which helps with uniform cooling and heat exchange. The drain hole 3 ensures water can flow on both sides of the partition 2, maintaining the water level balance within the cooling tank 1, promoting the circulation of cooling water, and ensuring the stability and continuity of the cooling effect. The PLC controller 6 intelligently controls the operation of the cooling mechanism 4 and circulation mechanism 5, automatically adjusting the speed of the servo motor 43 based on the water temperature data fed back by the temperature sensor 7. The system controls cooling by controlling parameters such as the power of the semiconductor cooling plate 47 and the flow rate of the circulating pump 52. A temperature sensor 7 monitors the water temperature inside the cooling tank 1 in real time, providing accurate temperature data to the PLC controller 6. This allows the device to adjust its operating status promptly based on the actual water temperature, ensuring the cooling water temperature remains within a suitable range. The bottom of the placement box 8 is designed with a filter screen to store non-magnetic steel forgings, facilitating placement and transfer during the cooling process. The heat-conducting plate 41 tightly connects the cooling water inside the cooling tank 1 to the external environment. Its high thermal conductivity rapidly transfers heat from the water to the outside, increasing the heat dissipation area, accelerating heat dissipation, and effectively reducing the cooling water temperature, providing a low-temperature cooling environment for the non-magnetic steel forgings. Mounting plate 42 provides a stable mounting base for servo motor 43. Servo motor 43, as a power source, controls the speed and direction of the stirring rod 44. Stirring ensures a uniform temperature distribution of the cooling water in the cooling tank 1, preventing localized overheating or undercooling. Driven by servo motor 43, stirring rod 44 agitates the cooling water in the cooling tank 1, promoting water flow and heat exchange, accelerating heat transfer, and ensuring a more even distribution of the cooling energy generated by the semiconductor cooling plate 47 and the heat dissipated by the heat-conducting plate 41 in the water, thus improving overall cooling efficiency. Cooling shell 45 provides a protective space for the semiconductor cooling plate 47 and the electric fan 49, while air vent 46 provides a passage for cold air circulation, ensuring the semiconductor cooling plate 47... The cold air generated by 7 can be blown out smoothly and evenly diffused into the water in the cooling tank 1, enhancing the cooling effect. The semiconductor cooling plate 47 uses the Peltier effect to convert electrical energy into cold energy, precisely control the cooling capacity, and quickly reduce the ambient air temperature, providing a low-temperature environment for the cooling water. This compensates for the shortcomings of relying solely on the heat conduction plate 41 for heat dissipation, greatly improving the cooling efficiency. The mounting slot 48 provides a precise installation position for the electric blower fan 49, ensuring that the fan is firmly installed and operates stably. The electric blower fan 49 accelerates the airflow, quickly and evenly blowing the cold air generated by the semiconductor cooling plate 47 into the cooling water in the cooling tank 1, promoting heat exchange between the cold air and the water, accelerating the cooling speed of the cooling water, and ensuring the cooling effect.

[0029] Specifically, such as Figure 2 , Figure 3As shown, the servo motor 43 is mounted on the top of the mounting plate 42, and the top of the stirring rod 44 is connected to a connecting shaft via a flat key. The connecting shaft is rotatably connected to the bottom of the mounting plate 42. The output end of the servo motor 43 at the bottom passes through the mounting plate 42 and is fixedly connected to the top of the connecting shaft. The cooling shell 45 is welded to both sides of the top right side of the cooling box 1. The air vent 46 is opened at the bottom inside the cooling shell 45. The semiconductor cooling plate 47 is mounted at the bottom inside the cooling shell 45. The mounting groove 48 is opened at the top of the cooling shell 45. The electric fan 49 is installed inside the mounting groove 48.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the circulation mechanism 5 includes a water pumping pipe 51, a circulation pump 52, a diversion pipe 53, a connecting pipe 54, a fixing plate 55, and several nozzles 56. The water pumping pipe 51 is fixedly connected to the rear side of the inner right side of the cooling box 1.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the circulating pump 52 is installed at the bottom of the rear side of the cooling tank 1, the rear side of the water pump 51 is fixedly connected to the front side of the circulating pump 52, the diversion pipe 53 is fixedly connected to the rear side of the circulating pump 52, and the connecting pipe 54 is fixedly connected to the inner side of the fixing plate 55.

[0032] In this embodiment: by setting up a water pumping pipe 51, cooling water after cooling in the cooling tank 1 can be drawn to ensure that the cooling water can be recycled in a timely manner. The circulation pump 52 pressurizes and delivers the cooling water drawn by the water pumping pipe 51 to ensure that the cooling water has sufficient pressure and flow to complete the circulation. The diversion pipe 53 is connected to the circulation pump 52 to evenly distribute the concentrated water flow output by the circulation pump 52, so that the cooling water can be distributed to each connecting pipe 54. The connecting pipe 54 plays a connecting role, delivering the water flow distributed by the diversion pipe 53 to the nozzle 56. The fixing plate 55 provides a stable installation support for the connecting pipe 54 and the nozzle 56. The nozzle 56 sprays the cooling water delivered by the connecting pipe 54 in a uniform water mist, increasing the contact area between the cooling water and the non-magnetic steel forging round and improving the cooling efficiency.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, the side of the diversion pipe 53 away from the circulating pump 52 is fixedly connected to the top of the connecting pipe 54, the fixing plate 55 is welded to the left side of the top of the cooling box 1, the nozzle 56 is installed at the bottom of the fixing plate 55, and the bottom of the connecting pipe 54 passes through the fixing plate 55 and is fixedly connected to the top of the nozzle 56.

[0034] Specifically, such as Figure 2 As shown, the bottom of the left inner side of the cooling box 1 is set as a slope, and the inner side of the cooling box 1 is coated with anti-corrosion paint.

[0035] In this embodiment: by setting the bottom of the inner left side of the cooling tank 1 as a slope, the cooling water is guided to converge to the right side of the cooling tank 1 by gravity. By applying an anti-corrosion coating, the cooling water is isolated from direct contact with the metal of the tank body, resisting the erosion of water and any corrosive substances, preventing the tank body from rusting and perforating, and extending the service life of the cooling tank 1.

[0036] Specifically, such as Figure 3 As shown, a dust filter 9 is fixedly connected to the top of the inner side of the mounting groove 48, and the surface of the dust filter 9 is coated with an anti-corrosion coating.

[0037] Specifically, such as Figure 4 As shown, a reinforcing base 10 is fixedly connected to the bottom of the circulating pump 52, and the surface of the reinforcing base 10 is coated with an anti-corrosion coating.

[0038] In this embodiment: By setting a dust filter 9, dust, debris and other particles are intercepted from entering the interior of the cooling shell 45, preventing components such as the semiconductor cooling plate 47 and the electric fan 49 from being affected by dust accumulation and thus affecting heat dissipation and operating efficiency. By setting an anti-corrosion coating, the filter is prevented from rusting and clogging in humid and water-vapor environments, keeping the filter pores unobstructed and maintaining long-term dustproof performance. By setting a reinforcing base 10, the installation stability of the circulating pump 52 is enhanced, the vibration generated during pump operation is dispersed, and the risk of parts loosening and pipe connections falling off due to vibration is reduced. By setting an anti-corrosion coating, the reinforcing base 10 is protected from cooling water splashes and erosion in humid environments, thus preventing a decrease in structural strength.

[0039] Working Principle: First, the operator places the non-magnetic steel forging round into the placement box 8. At this time, the operator controls the circulation pump 52 to start via the PLC controller 6. The cooling water in the cooling tank 1 begins to initially cool the forging round through the nozzle 56. After the cooling water comes into contact with the forging round, it leaks through the filter screen at the bottom of the placement box 8 into the inner left side of the cooling tank 1. The cooling water then flows back into the inner right side of the cooling tank 1 through the drain hole 3. At this time, the temperature sensor 7 begins to monitor the water temperature in the cooling tank 1 in real time and feeds the data back to the PLC controller 6. Then, when the water temperature rises, the heat conduction plate 41, with its high thermal conductivity, quickly conducts the heat in the cooling water to the outside of the cooling tank 1. Finally, the PLC controller 6 controls the servo motor 43 to drive the stirring rod 44 to rotate, thus cooling the water. Stirring is performed to ensure uniform water temperature distribution and promote heat exchange. Simultaneously, the PLC controller 6 controls the semiconductor cooling plate 47 and the electric blower fan 49 to start. The semiconductor cooling plate 47 generates cold energy through the Peltier effect, and the electric blower fan 49 blows cold air through the air inlet 46 to the cooling water, accelerating the water temperature drop. Then, the water pump 51 draws the cooled water from the cooling tank 1, and the circulation pump 52 pressurizes and delivers it to the distribution pipe 53. The distribution pipe 53 evenly distributes the water flow to each connecting pipe 54, and finally sprays it out in the form of water mist through the nozzle 56 at the bottom of the fixed plate 55, evenly spraying it on the surface of the non-magnetic steel forging round, realizing the recycling of cooling water, ensuring that the cooling water temperature is maintained within a suitable range, achieving efficient and uniform cooling of the non-magnetic steel forging round, thereby eliminating the annular defects in the flaw detection.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
