Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a quenching equipment for high-speed steel heat treatment technology. Background Technology

[0002] Quenching equipment is a device used for heat treatment of metallic materials. Its core process is to heat the metal to a specific temperature and then quickly immerse it in a cooling medium, so that the internal structure of the metal changes from austenite to martensite or bainite, thereby improving the hardness, strength and wear resistance of the material.

[0003] During the quenching process, after the steel is heated to a certain temperature, it needs to be clamped and fixed and transferred to a cooling water tank. Using common clamps to clamp and fix high-temperature steel cannot guarantee absolute stability. If it falls or loosens during the transfer, there will be a great safety risk, and the overall operation is also relatively troublesome. Utility Model Content

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.

[0017] Please see Figure 1-3This utility model provides a technical solution: including an electrical cabinet 1 and a water tank 2. The upper end of the water tank 2 is provided with a pair of lifting holes 21. The lifting hole 21 near the side of the electrical cabinet 1 is provided with an electric heating tube 3. The end of the electric heating tube 3 is connected to the inside of the electrical cabinet 1. A central rotating shaft 4 is rotatably connected to the middle position of the upper end of the water tank 2. An end plate 41 is fixed to the upper end of the central rotating shaft 4. An end telescopic cylinder 42 is fixed on the end plate 41 and at the position aligned with the lifting hole 21. An electromagnetic fixing head 43 is fixed to the output end of the end telescopic cylinder 42. A lifting plate 7 is installed inside the water tank 2. A carrier plate 74 is fixed on the upper end of the lifting plate 7 at the position corresponding to the lifting hole 21. A material rack 5 is fixed to the periphery of the lifting hole 21 on the side of the upper end of the water tank 2 away from the electrical cabinet 1. The material rack 5 has a door-shaped structure.

[0018] The bottom of the central rotating shaft 4 is located inside the water tank 2 and is fixedly connected to a gear shaft 71. The gear shaft 71 passes through the lifting plate 7 and is slidably connected to the lifting plate 7. An annular plate 72 is installed at the bottom of the lifting plate 7. The lifting plate 7 is rotatably connected to the upper end of the annular plate 72. A bottom telescopic cylinder 73 is fixed between the bottom of the annular plate 72 and the bottom of the water tank 2.

[0019] A fixed bevel gear 44 is fixed on the central rotating shaft 4, and a servo motor 22 is fixed on the upper end of the water tank 2. A drive bevel gear that meshes with the fixed bevel gear 44 is fixed at the output end of the servo motor 22.

[0020] A temperature sensor is fixed inside the water tank 2, and a heat sink 6 is fixed outside the electrical cabinet 1. A circulating heat sink pipe is installed between the water tank 2 and the heat sink 6. A circulating pump 61 is fixed on the side wall of the heat sink 6 at a position corresponding to the circulating heat sink pipe.

[0021] Working principle: First, connect the entire device to an external power source. Then, place the steel on the rack 5. Using the extension and retraction of the telescopic cylinder and the adsorption and fixation of the electromagnetic fixing head 43, the steel can be lifted. Then, by rotating the end plate 41, the steel can be moved to directly above the heating tube 3 and placed inside the heating tube 3. At the same time, the electromagnetic fixing head 43 is reset. By energizing the heating tube 3, the steel can be heated quickly. After heating, the lifting plate 7 can be driven to descend, bringing the carrier plate 74 and the heated steel into the water tank 2 simultaneously. The water in the water tank 2 is used to quickly cool the steel, achieving the purpose of quenching. Then, the central rotating shaft 4 drives... Rotating the gear shaft 71 drives the lifting plate 7 to rotate, aligning the cooled steel with the material rack 5 and simultaneously lifting it so that the steel extends out of the water tank 2 and is positioned below the material rack 5 for easy material handling. Throughout the process, after heating the steel, no transfer operation is required, improving safety and ease of operation. During the rotation of the lifting plate 7, its end plate 41 also rotates, allowing for the loading of the next piece, achieving continuous operation. Finally, a temperature sensor monitors the water temperature in the water tank 2, and a circulating pump 61 circulates the water between the water tank 2 and the heat sink 6, maintaining the water in the water tank 2 at a reasonable temperature.
