Description

Technical Field

[0001] The utility model relates to the technical field of butterfly spring processing, in particular to a surface quenching device for butterfly spring processing. Background Art

[0002] Currently, belleville springs require quenching during production. Quenching is a crucial process in heat treatment production and a key step in improving the overall performance of workpieces. While various quenching media are available, quenching oil is still the most widely used. During quenching, as the hot workpiece is immersed in the quenching oil, the oil burns violently, producing large clouds of fumes. Once the workpiece is fully immersed in the quenching oil, the combustion ceases, but fumes still escape from the surface of the quenching oil. This fumes have a strong, pungent odor and contain large amounts of carcinogens such as benzopyrene. Long-term inhalation can pose a significant health risk to workers.

[0003] In order to better adapt to the quenching of different workpieces, the device for extracting oil smoke in the existing technology generally sets the range hood to be larger to facilitate the loading of workpieces. However, this makes it easy for the oil smoke to escape and is not easy to be collected by the range hood. Therefore, the efficiency of extracting oil smoke by this device is low, the extraction effect is not good, and smokeless quenching cannot be achieved, which still poses a hazard to the workers.

[0025] Example 2:

[0026] As shown in the attached figure of the instruction manual Figure 1 、 Figure 2 and Figure 3As shown, a surface quenching device for butterfly spring processing is used. When in use, the movable plate 18 is first slid outward through the slide groove 17, and then the spring to be quenched is placed on the top of the movable plate 18, and then the movable plate 18 is slid inward to return it to its original position. Through the coordinated use of the slide groove 17 and the movable plate 18, the movable plate 18 can be pulled out after the quenching is completed, which is convenient for the operator to place and remove the spring, thereby increasing work efficiency. Then the operator starts the driving motor 6 through the control panel 3, and the driving motor 6 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the main gear 8 to rotate, and the main gear 8 drives the driven gear 9 to rotate, and the driven gear 9 drives the threaded rod 10 to rotate.
