[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0029] The present application will be further described below in combination with embodiments.

[0030] In some embodiments, refer to the attached drawings of the specification Figures 1-4 , a spheroidizing annealing device for bolt processing, comprising: a box body 1 and a conveyor belt 2 arranged inside it. Holes 5 for limiting bolts are formed on the surface of the conveyor belt 2. Spray pipes 3 are arranged in the middle and above the conveyor belt 2; a lifting component 6, which is arranged in the conveyor belt 2 and both ends of which are fixedly connected to the inner wall of the box body 1;

[0031] In the spheroidizing annealing process of bolts, cooling usually occurs after the heating process ends. When the steel has reached the required annealing temperature and is maintained for a period of time to ensure that the carbide is completely transformed into a spherical shape, at this time, it is necessary to slowly cool the workpiece to avoid generating internal stress or deformation. At this time, the above-mentioned spray pipe 3 and the lifting component 6 can be used to cool the bolts that have undergone the spheroidizing annealing process evenly and efficiently;

[0032] In some embodiments, as Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the lifting component 6 includes a lifting frame 601 fixedly connected to the inner wall of the box body 1 and located in the middle of the conveyor belt 2. The lifting frame 601 is located above one of the spray pipes 3 and is designed in an "L" shape. When in use, first, two driving rollers 4 drive the conveyor belt 2 to move. At this time, the bolts in the holes 5 of the conveyor belt 2 will move along with the conveyor belt 2. When the bolts move, the two spray pipes 3 in the middle and above the conveyor belt 2 will blow air to cool the bolts simultaneously. However, due to the small windward area of the bolts in the holes 5 of the conveyor belt 2, when the bolts approach the lifting frame 601 along with the conveyor belt 2, first, the bolts contact the inclined part 603 of the lifting frame 601, and then the bolts gradually rise along with the movement of the conveyor belt 2 along with the angle of the inclined part 603, so that the parts that were originally in the holes 5 can be exposed. At this time, the upper spray pipe 3 can blow cold air to the surface of the bolts to cool the bolts in multiple directions. After the bolts move up to a certain position along with the conveyor belt 2, they will fall into the wrapping groove 602 of the lifting frame 601. At this time, the spray pipe 3 in the middle of the conveyor belt 2 will blow cold air into the wrapping groove 602, so that the cold air can circulate in a ring in the wrapping groove 602, so that the parts of the bolts in the wrapping groove 602 can be blown comprehensively, achieving the effect of cooling the bolts evenly;

When the bolts approach the lifting frame 601 along with the conveyor belt 2, first, the bolts contact the inclined part 603 of the lifting frame 601, and then the bolts gradually rise along with the movement of the conveyor belt 2 along with the angle of the inclined part 603, so that the parts that were originally in the holes 5 can be exposed. At this time, the upper spray pipe 3 can blow cold air to the surface of the bolts to cool the bolts in multiple directions

[0034] In the embodiment of the utility model, the surface of the inclined part 603 is provided with a limiting groove 604, and the slope of the limiting groove 604 is consistent with the inclined part 603; by arranging the limiting groove 604, the lower end of the bolt can be limited when the bolt rises along with the transmission belt 2 on the surface of the inclined part 603, so that the bolt is prevented from tilting;

[0035] In the embodiment of the utility model, the lifting frame 601 is provided with a wrapping groove 602 on the side away from the inclined part 603, and the inner wall of the wrapping groove 602 is arc-shaped; after the bolt is moved upward to a certain position along with the transmission belt 2, the bolt falls into the wrapping groove 602 of the lifting frame 601, at this time, the spray pipe 3 in the middle of the transmission belt 2 blows cold air into the wrapping groove 602, so that the cold air can circulate in the wrapping groove 602, thereby comprehensively blowing the bolt part in the wrapping groove 602, and the bolt is uniformly cooled

[0036] In the embodiment of the utility model, the wrapping groove 602 and the limiting groove 604 are both provided with a plurality of rectangular arrays, and the inner bottom of the groove body of the wrapping groove 602 is communicated with the limiting groove 604;

[0037] In the embodiment of the utility model, the surfaces of the two spray pipes 3 are both provided with spray openings, and the spray opening angles of the two spray pipes 3 are oppositely arranged; by the above arrangement, the bolt can be continuously blown, and the bolt cooling efficiency is improved;

[0038] In the embodiment of the utility model, the spray pipe 3 in the middle of the transmission belt 2 is oppositely arranged with the wrapping groove 602;

[0039] In the embodiment of the utility model, the inner two sides of the transmission belt 2 are both provided with driving rollers 4, and the front side and the rear side of the driving roller 4 are both fixedly connected with the inner wall of the box body 1 through bearing seats; by the driving roller 4, when the bolt needs to be cooled, the two driving rollers 4 are first driven to be opened by an external motor, then the transmission belt 2 is driven, at this time, the bolt in the hole 5 of the transmission belt 2 is displaced along with the transmission belt 2, so that each bolt can be individually blown, and the processing quality of the bolt is improved.
