Description

Technical Field

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

[0002] Guide wheels are key components in mechanical transmission and conveying systems, widely used in mining machinery, lifting equipment, conveying machinery, and construction machinery. In these applications, guide wheels need to withstand significant loads, friction, and frequent start-stop impacts. Their surface wear resistance, overall strength, and service life directly affect the operational stability and safety of the equipment.

[0003] To meet the above requirements, guide wheels are typically made of medium carbon steel or alloy structural steel, and quenching is the core process for improving their performance. Unquenched guide wheels have low surface hardness and are prone to wear and deformation under long-term friction and load. This not only shortens their service life but may also lead to decreased equipment operating accuracy, frequent malfunctions, and even safety accidents.

[0004] The core of quenching is to heat the metal workpiece to above the critical temperature (usually several hundred to thousands of degrees Celsius) and then cool it rapidly (such as by immersing it in water, oil or other media). However, even after cooling, the surface temperature of the workpiece may still be much higher than the temperature that the human body can tolerate (generally, temperatures above 50°C can cause burns). Traditional processing lacks a precise detection and real-time warning mechanism for the temperature of the guide wheel after quenching, making it difficult to determine whether the workpiece has reached a safe contact temperature.

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-4 A quenching device includes a quenching machine body 1. A first mounting frame 7 is provided on the quenching machine body 1. A quenching component and a temperature measuring component are mounted on the first mounting frame 7. The temperature measuring component includes a mounting base 18 connected to the first mounting frame 7 via a second connecting frame 17. An infrared temperature sensor integrated 21 for measuring the temperature of a guide wheel after quenching is mounted on the mounting base 18. An adjustment component for adjusting the position of the infrared temperature sensor integrated 21 is provided on the mounting base 18. By adjusting the position of the infrared temperature sensor integrated 21 using the adjustment component, the temperature of the guide wheel after quenching can be measured at the optimal distance using the infrared temperature sensor integrated 21. If the temperature of the guide wheel is too high, an alarm light 23 will be activated to prevent workers from directly handling the guide wheel after quenching and being burned.

[0028] Furthermore, the adjustment component includes a lead screw 22 rotatably connected to the mounting base 18. It should be noted that the lead screw 22 can be driven to rotate manually or electrically. In order to save energy, this solution preferably adopts manual driving.

[0029] Furthermore, a slider 20 is movably disposed below the mounting base 18. The slider 20 has a threaded groove adapted to the lead screw 22. The slider 20 is fixedly connected to the infrared temperature sensor integrated 21. By driving the lead screw 22 to rotate, the slider 20 can slide along the slide groove 19. The slider 20 drives the infrared temperature sensor integrated 21 to adjust the distance between it and the guide wheel. After changing the guide wheel of different sizes, the infrared temperature sensor integrated 21 can be adjusted to the optimal temperature measuring distance of the electric push rod 3.

[0030] Furthermore, the mounting base 18 is provided with a sliding groove 19 for the slider 20 to slide, which can play a limiting and guiding role to prevent the slider 20 from deviating.

[0031] Furthermore, the main body 1 of the quenching machine tool is provided with a first connecting frame 2, and an electric push rod 3 is installed on the first connecting frame 2. This is an existing product and is used by connecting to an external power supply. The output end of the electric push rod 3 is provided with a connecting seat 4, and the bottom of the connecting seat 4 is provided with a base 5. A turntable 8 for placing guide wheels is installed on the base 5.

[0032] Furthermore, a mounting groove 9 is provided on the top surface of the turntable 8, and a three-jaw chuck 10 is installed inside the mounting groove 9 for fitting and clamping against the inner wall of the guide wheel. The three-jaw chuck 10 is also provided with a moving rod for driving the three-jaw chuck 10 to work. The driving rod is arranged through the turntable 8 and rotatably connected to the turntable 8. The three-jaw chuck 10 can ensure the stability of the rotation and heating of the guide wheel, and can also clamp guide wheels of different sizes.

[0033] Furthermore, a rotation drive assembly is provided below the base 5;

[0034] The rotation drive assembly includes a servo motor 6 mounted on the bottom surface of the base 5, which is also connected to an external power supply. The output end of the servo motor 6 is provided with a transmission shaft, which is rotatably connected to the base 5. The upper end of the transmission shaft is fixedly connected to the turntable 8. By starting the servo motor 6, the transmission shaft is driven to rotate, which in turn drives the turntable 8 above to rotate the guide wheel during the heating process, so that the guide wheel can be heated evenly.

[0035] Furthermore, the quenching machine tool body 1 is equipped with an alarm light 23, and the alarm light 23 is connected to the infrared temperature sensor integration 21. It should be noted that the infrared temperature sensor integration 21 and the alarm light 23 are existing products and are only used on them. If the temperature measured by the infrared temperature sensor integration 21 exceeds the specified threshold, the alarm light 23 will sound an alarm to remind the staff that the guide wheel is too high after quenching.

[0036] Furthermore, the quenching assembly includes a heating unit and a cooling unit;

[0037] The heating unit includes an electromagnetic heating controller integrated 15 mounted on the main body 1 of the quenching machine tool. The electromagnetic heating controller integrated 15 is equipped with an electromagnetic induction coil 16. It should be noted that the electromagnetic heating controller integrated 15 and the electromagnetic induction coil 16 are existing products. The electromagnetic heating controller integrated 15 typically first rectifies the three-phase power frequency AC power into DC power, and then converts the DC power into adjustable high-frequency AC power through IGBT inverter technology to supply the induction coil. It is only used for this purpose.

[0038] The cooling unit includes a second mounting bracket 13 mounted on the first mounting bracket 7 and located directly below the electromagnetic induction coil 16. The inner side of the second mounting bracket 13 is provided with nozzles 14 arranged in a ring array. The quenching machine tool body 1 is provided with a water tank 11. The water tank 11 is connected to multiple nozzles 14 through a connecting pipe 12. The water tank 11 is provided with a water pump inside to pump out the water inside the water tank 11.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
