Description

Technical Field

[0001] The utility model relates to the technical field of quenching and cooling equipment, in particular to a quenching and cooling device for producing miniature nuts. Background Art

[0002] In the high-precision manufacturing process of micro-nuts, quenching and cooling are key steps, and their efficiency and effectiveness are directly related to the final quality and market competitiveness of the product. However, traditional quenching and cooling technologies currently on the market face multiple challenges. First, traditional devices have bottlenecks in cooling efficiency, making it difficult to achieve rapid and uniform cooling of high-temperature micro-nuts. This often leads to uneven quenching effects, affecting the mechanical properties and microstructure of the nuts.

[0003] Secondly, the lack of water quality management has become another major pain point. Due to the lack of effective filtration and circulation mechanisms, cooling water used for a long time is prone to accumulate various impurities such as metal debris and oil stains. This not only reduces cooling efficiency, but also accelerates equipment aging and increases maintenance costs. To this end, we provide a quenching and cooling device for the production of micro nuts. Utility Model Content

[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, one embodiment of the present invention provides a quenching and cooling device for producing miniature nuts. First, a cooling water tank 1 is constructed as the main structure, within which a sliding mounting frame 2 is designed. Hydraulic cylinders 3 are mounted on either side of the cooling water tank 1. The output end of the hydraulic cylinder 3 is fixedly connected to an L-shaped plate 4, the other end of which is fixedly connected to the upper surface of the mounting frame 2. Thus, the expansion and contraction of the hydraulic cylinder 3 drives the mounting frame 2 up and down within the cooling water tank 1, enabling the miniature nuts to be immersed and extracted.

[0026] The mounting frame 2 houses a nut rack 5 for quenching miniature nuts. The front of the cooling water tank 1 features a strip-shaped through-slot 6, through which a filter plate 7 is inserted to filter impurities from the cooling water. To prevent the filter plate 7 from sliding out during use, a retaining mechanism is designed. This mechanism comprises a connecting plate 9 and a strip-shaped mounting slot 10. The connecting plate 9 is fixedly connected to the filter plate 7, and the strip-shaped mounting slot 10 houses a vertical support rod 11, a spring 12, and a movable sleeve 13. Under the elastic force of the spring 12, the movable sleeve 13 is pressed against the connecting plate 9 through the limit baffle 14 to prevent it from sliding out. At the same time, a sealing component is provided between the cooling water tank 1 and the connecting plate 9 to ensure the sealing of the cooling water; the upper end of the spring 12 is fixedly connected to the end wall of the strip-shaped placement groove 10, and the lower end is fixedly connected to the upper end surface of the movable sleeve 13. In this way, under the elastic force of the spring 12, the movable sleeve 13 can automatically reset and drive the limit baffle 14 to press against the connecting plate 9, thereby realizing the stable installation of the filter plate 7.

[0027] Furthermore, a sealing slot 15 is provided on the front of the cooling water tank 1, and a sealing insert 16 is fixedly connected to the back of the connecting plate 9. The sealing insert 16 is inserted into the sealing slot 15, and the sizes of the two are adapted to each other to ensure the sealing effect; the design of the sealing component effectively prevents the leakage of cooling water and improves the safety and reliability of the device; in order to facilitate the disassembly and maintenance of the nut placement rack 5, a disassembly structure is designed. The structure includes a mounting block 18 and a threaded hole 19. The mounting block 18 is fixedly connected to the inner end wall of the mounting frame 2, and the threaded hole 19 is provided on the surface of the mounting block 18. The surface of the nut placement rack 5 is threadedly connected to the tightening screw 20. The nut placement rack 5 can be fixed and disassembled by rotating the tightening screw 20; the design of the disassembly structure simplifies the replacement process of the nut placement rack 5 and improves maintenance efficiency.

[0028] Furthermore, in order to support the filter plate 7 and facilitate its removal and cleaning, a mounting frame 8 is fixedly connected to the inner wall of the cooling water tank 1. At the same time, a pulling handle 17 is provided on the front of the connecting plate 9 to facilitate the operator to manually pull out the filter plate 7 for cleaning or replacement; the threaded section of the tightening screw 20 passes through the nut placement rack 5 and is threadedly connected to the threaded hole 19, and the sizes of the two are adapted to each other. This design ensures the stability of the nut placement rack 5 during installation and the convenience of disassembly.

[0029] Among them, the design of the mounting frame 8 and the pulling handle 17 improves the usability and maintainability of the filter plate 7; the tight fit between the tightening screw 20 and the threaded hole 19 improves the fixing effect and service life of the nut placement rack 5.
