DETAILED DESCRIPTION

[0017] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center," "middle," "upper," "lower," "left," "right," "inner," "outer," "top," "bottom," "side," "vertical," "horizontal," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, the terms "one," "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that the embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of the embodiments. In addition, all embodiments may be used in combination with each other.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a continuous quenching device for preparing CNC tools made of CBN composite materials, comprising a heating furnace 1, a conveyor frame 2 is provided at the outlet of the right end of the heating furnace 1, and a transmission belt 3 is correspondingly provided at the end of the conveyor frame 2; a quenching tank 7, an inner end of the quenching tank 7 is fixedly connected to an arrangement frame 4, an inner end of the arrangement frame 4 is provided with a separation structure, the separation structure includes a blocking plate 10, and the rotating shafts at both ends of the blocking plate 10 are connected to the inner ends of the arrangement frame 4; a circulating liquid pump 5, an output end of the circulating liquid pump 5 is connected to a circulation pipe 6, and the ends of the circulation pipe 6 are connected to the two sides of the quenching tank 7. After the tool is heated in the heating furnace 1 and naturally cooled at a relatively slow speed for a period of time, it enters the quenching tank 7 filled with quenching oil through the conveyor frame 2 and is conveyed to the desired position in the transmission belt 3. At the same time, the circulating liquid pump 5 can circulate the quenching oil in the quenching tank 7 through the circulation pipe 6. This prevents the quenching oil around the tool from being heated and unable to circulate the lower temperature quenching oil in time during the quenching process of the transmission belt 3, resulting in reduced quenching efficiency.

[0022] A plurality of elastic brackets 9 are fixedly connected to the front side of the lower end of the arranging frame 4, and the ends of the elastic brackets 9 are fixedly connected to the rear end face of the blocking plate 10. A plurality of supporting springs 12 are fixedly connected to the rear side of the lower end face of the arranging frame 4, and the lower ends of the supporting springs 12 are fixedly connected to the supporting plate 14. The lower end of the supporting plate 14 is fixedly connected to the separating rod 13. The side end face of the supporting plate 14 is fixedly connected to the stabilizing limit groove 15, and the stabilizing frame 11 is slidably inserted in the stabilizing limit groove 15. The stabilizing frame 11 is fixedly connected to the rear side of the lower end face of the arranging frame 4. When the tool enters the transmission belt 3 from the conveying frame 2, if stacking occurs, it can be blocked by the blocking plate 10. At the same time, due to the elastic support of the elastic bracket 9, the blocking plate 10 can fit as close as possible to the upper surface of a single tool during blocking, thereby blocking the stacked tools. The separating rod 13 separates the tools that are in contact on the sides from each other to prevent sticking.

[0023] Filters 8 are fixedly connected to both end surfaces of the inner side of the quenching tank 7. The transmission belt 3 is arranged in the quenching tank 7. The filter 8 prevents debris during quenching from entering the circulation pipe 6 and causing blockage.

[0024] In actual use, the tool is heated in the heating furnace 1 and naturally cooled at a slower speed for a period of time, and then enters the quenching tank 7 filled with quenching oil through the conveyor rack 2 and is conveyed to the desired position in the transmission belt 3. When the tool enters the transmission belt 3 from the conveyor rack 2, if stacking occurs, it can be blocked by the blocking plate 10. At the same time, due to the elastic support of the elastic bracket 9, the blocking plate 10 can fit as close to the upper surface of a single tool as possible during blocking to block the stacked tools. The separation rod 13 separates the tools that are in contact on the side to prevent sticking. At the same time, the circulating liquid pump 5 can circulate the quenching oil in the quenching tank 7 through the circulating pipe 6. This prevents the tool from being unable to circulate the lower temperature quenching oil in time due to the heating of the quenching oil around the tool during the quenching process of the transmission belt 3, resulting in reduced quenching efficiency.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
