Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment, specifically a heat treatment equipment for chain processing. Background Technology

[0002] Chains, as a classic mechanical component, are typically made of metal links or ring-shaped components precisely connected. Their robust structure and flexible connection methods make them indispensable in the industrial field, widely used in the transmission systems of various machines, the traction and lifting of heavy objects, and even the linkage mechanisms of precision instruments. However, during the manufacturing process of chains, especially when welding is involved, certain welding stresses inevitably remain inside the chain links. These internal stresses are like hidden "hazards," which, under long-term action, may cause chain deformation, decreased precision, or even breakage, thereby greatly shortening their expected service life and affecting the stable operation of the entire mechanical system.

[0003] Currently, heat treatment is a crucial step in chain processing, as it can significantly improve the mechanical properties and service life of the chain. However, traditional chain heat treatment devices generally suffer from uneven heating when processing chains, resulting in significant performance differences between different parts of the chain and affecting product quality. To address this, we propose a heat treatment device for chain processing. Utility Model Content

A heating device located inside the main cabinet heats the chain through a flame gun. During the chain's rotation, the heating device can provide uniform heating from all directions without any blind spots, ensuring that every part of the chain is fully and evenly heated. This fundamentally solves the problem of uneven heating during chain heat treatment.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0023] A heat treatment device for chain processing includes a main cabinet 1. A motor 15 is installed on the back of the main cabinet 1. The output end of the motor 15 passes through the main cabinet 1 and is connected to a rotating rod 16. An electric slide rail 17 is installed on the inner wall of the main cabinet 1. A slider 18 is slidably connected to the outer surface of the electric slide rail 17. A connecting rod 19 is rotatably connected to the outer surface of the slider 18. Placement rods 20 are connected to the outer surfaces of both the connecting rod 19 and the rotating rod 16. Chain teeth 21 are provided on the outer surfaces of both placement rods 20. This linkage structure enables the placement rods 20 to carry the chain and circulate within the cabinet, facilitating heat treatment of the chain.

[0024] In this embodiment, two heating devices 3 are installed inside the main cabinet 1. Each heating device 3 is equipped with two flame guns inside the main cabinet 1. The outer surfaces of the two heating devices 3 penetrate the main cabinet 1 and are connected to an air inlet pipe 4. External gas can enter the interior of the heating device 3 through the air inlet pipe 4.

[0025] In this example, the input ends of the two intake pipes 4 are connected to a three-way pipe 5, and the input end of the three-way pipe 5 is connected to a connecting pipe A6, so that gas can enter each intake pipe 4 from the connecting pipe A6.

[0026] In this example, the input end of the connecting pipe A6 is connected to the air pump 7, and the input end of the air pump 7 is connected to the air storage tank 8. In this way, the gas in the air storage tank 8 can be delivered by the air pump 7.

[0027] In this example, a coolant tank 9 is installed on the upper surface of the main cabinet 1, and a connecting pipe B10 is connected to the outer surface of the coolant tank 9 to provide and transport coolant.

[0028] In this example, the end of the connecting pipe B10 away from the coolant tank 9 is connected to a water pump 11, and the output end of the water pump (11) is connected to a water inlet pipe 12. This pipe is responsible for further transmission of the coolant.

[0029] In this example, the end of the water inlet pipe 12 away from the water pump 11 passes through the main cabinet 1 and is connected to the diversion pipe 14. The outer surface of the diversion pipe 14 is connected to multiple spraying devices 13, which are used to spray the coolant evenly onto the surface of the chain.

[0030] In this example, a flow channel 22 is provided at the bottom of the inner wall of the main cabinet 1, and a drain outlet 23 is installed on the inner wall of the main cabinet 1. A cabinet door 2 is hinged to the front of the main cabinet 1. The cabinet door 2 provides a passage for entering the cabinet to operate, place or take out the chain, and can be closed when the equipment is in use, so as to protect the internal components and provide heat insulation.

[0031] Working Principle: At the start of operation, gently open the cabinet door 2 of the main cabinet 1. Then, operate the slider 18 on the electric slide rail 17 via the control panel to allow the placement rod 20 to slide smoothly vertically upwards along the slide rail, providing ample operating space for suspending the chain to be processed. After the chain is securely mounted on the chain teeth 21 of the placement rod 20, return the placement rod 20 to its initial working position and close the cabinet door 2 to ensure a sealed processing environment. Subsequently, start the motor 15 installed on the back of the main cabinet 1. The motor 15 drives the connecting rod 19 to rotate, which in turn drives the placement rod 20 to rotate synchronously. At this time, the chain teeth 21 on the outer surface of the placement rod 20 are tightly engaged with the chain, achieving cyclic rotation of the chain during the heating process and ensuring uniform heating of all parts of the chain. Next, with the help of the stable air source provided by the air tank 8, the heating device 3 is started. The heating device 3 heats the continuously rotating chain from all directions without dead angles to achieve the required heat treatment effect. When the heating process is completed, the system automatically switches to the cooling stage. The coolant tank 9 at the top of the main cabinet 1 delivers the pre-cooled coolant to the spray device 13. The spray device 13 then sprays the high-temperature chain evenly and finely to cool it, quickly reducing the chain temperature and fixing its structure. If too much coolant accumulates at the bottom of the cabinet during the process, it can be collected through the bottom guide channel 22 and discharged through the drain outlet 23 to prevent liquid overflow and keep the internal environment of the device clean and dry, preparing for the next efficient and safe use.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
