DETAILED DESCRIPTION

[0025] 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] The utility model will be further described below in combination with the embodiments.

[0027] In some embodiments, referring to the description attached hereto Figures 1-4 A quenching device for heat treatment of an elongated rod bolt includes a base plate 100 and two water boxes 110 mounted to the top of the base plate, a water guide mechanism 200 arranged above the base plate 100 and used to exchange and discharge the water sources in the two water boxes 110 and drive the water sources to flow. The water guide mechanism 200 includes two partitions 210 and two bent pipes 220. The two ends of the bent pipes 220 are respectively in communication with the interiors of the two water boxes 110. The partitions 210 are slidingly connected to the interiors of the water boxes 110

[0028] In the embodiment of the utility model, the bolt heated is transferred to the interior of one water box 110 for quenching and cooling treatment. After the quenching is completed, the bolt is transferred out. Then, the water sources in the two water boxes 110 are exchanged to ensure that the water source temperature in the interior of the water box 110 used for quenching is in a low-temperature state, thereby facilitating the next quenching operation.

[0029] In the embodiment of the utility model, when the water sources are replaced, the two partitions 210 are simultaneously driven to move, and the two bent pipes 220 are matched to squeeze and exchange the water sources in the two water boxes 110. During the whole water source exchange process, the water sources in the two water boxes 110 are not in contact, thereby ensuring the water source replacement effect.

[0030] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , as a preferred embodiment of the utility model, the water guide mechanism 200 further includes two rotating rods 230 and two groups of driving plates 240. The interior of the partition 210 is rotatably connected with a rotating ring 211 sleeved to the outside of the rotating rod 230. The two ends of the rotating rod 230 are both penetrated through and rotatably connected to the outside of the water box 110. The driving plate 240 is mounted to the outside of the rotating rod 230 and slidingly connected with the interior of the rotating ring 211.

[0031] During the quenching process, the rotating rod 230 can drive the corresponding driving plate 240 to rotate. The driving plate 240 moves to stir the water source, thereby improving the movement amplitude of the water source and helping the water source to produce a flocculent flow when it contacts the bolt, thereby assisting the cold water flow, improving the contact effect of the cold water and the bolt, ensuring the quenching effect, and matching the arrangement of the rotating ring 211 to normally perform the water source flow operation without affecting the normal movement of the partition 210.

[0032] In this embodiment of the invention, a servo motor 111 is installed between two water tanks 110. The output end of the servo motor 111 is fixedly connected to a lead screw 112 via a coupling. A threaded plate 212 extending to the outside of the water tank 110 is installed on one side of a partition 210. The internal threads of the threaded plate 212 are connected to the outside of the lead screw 112. When exchanging water between the two water tanks 110, the servo motor 111 is activated, which causes the lead screw 112 to drive the threaded plate 212 to move. Figure 2 As shown, at this time, the left partition 210 will squeeze the water source in the left water box 110 through the front folded pipe 220 and guide it into the right water box 110. At the same time, the partition 210 in the right water box 110 will be squeezed and pushed by the water flow. During its movement, the water source in the right water box 110 will also be guided into the left water box 110 along the back folded pipe 220. After the left partition 210 moves into place, the water source in the two water boxes 110 is exchanged. During the entire exchange process, the water sources in the two water boxes 110 do not come into contact, reducing the phenomenon of accidental mixing of low temperature water source and high temperature water source.

[0033] In this embodiment of the utility model, a sliding frame 120 is installed on the base plate 100, and a transfer barrel 130 is provided inside the sliding frame 120. A heating furnace 140 is installed on the bottom of the transfer barrel 130 and mounted on the base plate 100. An electric hoist 150 for driving the transfer barrel 130 is provided on the inner top wall of the sliding frame 120. Two guide rails are provided between the sliding frame 120 and the base plate 100, and an electric slide table 160 for driving the sliding frame 120 is installed on the guide rails. The bolt is supported by the transfer barrel 130 and placed into the heating furnace 140 for heat treatment. When quenching is required, the electric hoist 150 is used to lift the transfer barrel 130, and then the electric slide table 160 is used to drive the sliding frame 120 to move to the corresponding water box 110. Then the transfer barrel 130 is lowered for quenching treatment.

[0034] In this embodiment of the invention, a thermoelectric cooler 113 is mounted on a water tank 110. The heating end of the thermoelectric cooler 113 is located on the outside of the water tank 110, and the cooling end of the thermoelectric cooler 113 is located inside the water tank 110. Figure 2 As shown, the use of a semiconductor cooling chip 113 allows water from the left water box 110 to be transferred to the right water box 110 after quenching, so that low-temperature water enters the left water box 110. Then, the semiconductor cooling chip 113 is activated to quickly cool the high-temperature water after quenching, facilitating the next water exchange operation.

[0035] In the embodiment of the utility model, the outer side of rotary rod 230 is fixedly provided with synchronous wheel 231, and the outer side of two synchronous wheels 231 is drivingly connected with synchronous belt 232; the outer side of one water box 110 is provided with motor 114, and the output shaft of motor 114 is fixedly connected with one end of one rotary rod 230 through a shaft coupling; starting motor 114 can make corresponding rotary rod 230 rotate, and the setting of synchronous wheel 231 and synchronous belt 232 can make two rotary rods 230 drive two groups of driving plates 240 to move, one group of driving plates 240 drives the water source in the quenching process, and the contact effect of the cold water and the bolt is assisted, and the other group of driving plates 240 makes the water source in the refrigeration area of semiconductor refrigerating fin 113 flow, and the temperature of the water source in the water box 110 is assisted, and the phenomenon of uneven water source temperature is reduced.

[0036] In the embodiment of the utility model, rotary rod 230 is located in the central area of water box 110 and its height is lower than semiconductor refrigerating fin 113; it is convenient to have water source driving effect without affecting the quenching of transfer barrel 130.
