Description

Technical Field

[0002] As Figure 1 For the crawler skeleton 6 shown, after forging and forming, quenching processing is required. In the prior art, generally, several skeletons are stacked in a basket and the whole is sent into a heating furnace for heating, and then the whole is sunk into water for quenching. In this way, since the skeletons are stacked together, the overall cooling time is slow. At the same time, with many skeletons stacked together, the positions where the skeletons contact each other are heated and cooled unevenly. Utility Model Content

[0003] The purpose of the present application is to provide a quenching device for the production of crawler iron tooth skeletons to solve the problems raised in the above background technique.

[0004] To achieve the above object, the present application provides a quenching device for the production of crawler iron tooth skeletons, adopting the following technical solution:

[0005] A quenching device for the production of crawler iron tooth skeletons includes an intermediate frequency quenching furnace and a water storage tank arranged beside the intermediate frequency quenching furnace. A chain conveyor belt is arranged between the intermediate frequency quenching furnace and the water storage tank. The chain conveyor belt is used to send the iron tooth skeletons in the intermediate frequency quenching furnace into the water storage tank. A skeleton guiding mechanism and an aggregate mesh box are arranged in the water storage tank. The skeleton guiding mechanism includes symmetrically arranged vertical plates. A material guiding channel is formed between the two vertical plates. Multiple inclined baffles are sequentially arranged at intervals from top to bottom in the material guiding channel. The upper and lower baffles are respectively fixedly connected to the vertical plates on both sides, and the skeletons in the upper baffle can slide onto the lower baffle.

[0006] The aggregate mesh box is used to collect the skeletons coming out of the material guiding channel.

[0007] Preferably, a rotating plate is arranged at the bottom of the material guiding channel. A rotating shaft is fixed in the middle of the rotating plate. The two ends of the rotating shaft are respectively rotatably connected to the side wall of the water storage tank. A waterproof oil cylinder is arranged at the bottom of one side of the rotating plate. The bottom end of the waterproof oil cylinder is fixed on the water storage tank. The end of the piston rod of the waterproof oil cylinder is connected to the bottom end of the rotating plate through a universal ball head.

[0008] The number of the aggregate mesh boxes is two. The two aggregate mesh boxes are respectively arranged on both sides of the material guiding channel. The rotating plate is used to guide the skeletons in the material guiding channel into the aggregate mesh boxes.

[0009] By adopting the above technical solution, two aggregate cages are arranged on the left and right. When the left aggregate cage is full, the waterproof oil cylinder drives the rotating plate to adjust the angle, so that the skeletons falling in the material guiding channel slide into the aggregate cage on the right. After the left aggregate cage is completely cooled, it is lifted by a crane, and then used in a left-right cycle in turn.

[0010] A plurality of water permeable holes are formed in the surfaces of the vertical plate and the baffle plate.

[0011] Preferably, in order to enable the aggregate cage to be lifted and positioned accurately in the reservoir flexibly, chutes are arranged on the inner wall of the reservoir, sliders are arranged at positions corresponding to the chutes on the aggregate cage, and lifting rings are fixed at the four corners of the top end of the aggregate cage.

[0018] The following will further describe the present application in detail Figures 2-4 with reference to the accompanying drawings.

[0019] The embodiment of the present application discloses a quenching device for producing a crawler iron tooth skeleton. Refer to Figures 2-4, including an intermediate frequency quenching furnace 1 and a water storage tank 2 arranged beside the intermediate frequency quenching furnace 1. The water storage tank 2 is sunken below the ground surface. A chain conveyor belt 3 is arranged between the intermediate frequency quenching furnace 1 and the water storage tank 2. The chain conveyor belt 3 is used to send the iron tooth framework in the intermediate frequency quenching furnace 1 into the water storage tank 2. A framework guiding mechanism and an aggregate mesh box 4 are arranged in the water storage tank 2. The framework guiding mechanism includes symmetrically arranged vertical plates 21. A material guiding channel is formed between the two vertical plates 21. A plurality of inclined baffles 22 are sequentially arranged at intervals from top to bottom in the material guiding channel. The upper and lower baffles 22 are respectively fixedly connected to the vertical plates 21 on both sides, and the framework in the upper baffle 22 can slide onto the lower baffle 22. A plurality of water permeable holes are formed on the surfaces of the vertical plates 21 and the baffles 22. The aggregate mesh box 4 is used to collect the framework coming out of the material guiding channel. In order to reduce the influence of water vapor in the workshop, an air extraction hood (not shown in the figure) is arranged beside the water storage tank 2, and the air extraction hood is externally connected with an air extraction fan.

[0020] Refer to Figure 4 , a rotating plate 23 is arranged at the bottom of the material guiding channel. A rotating shaft is fixed in the middle of the rotating plate 23. The two ends of the rotating shaft are respectively rotatably connected to the side walls of the water storage tank 2. A waterproof oil cylinder 24 is arranged at the bottom of one side of the rotating plate 23. The bottom end of the waterproof oil cylinder 24 is fixed on the water storage tank 2. The piston rod end of the waterproof oil cylinder 24 is connected to the bottom end of the rotating plate 23 through a universal ball head. The number of the aggregate mesh boxes 4 is two, and the two aggregate mesh boxes 4 are respectively arranged on both sides of the material guiding channel. The rotating plate 23 is used to guide the framework in the material guiding channel into the aggregate mesh box 4.

[0021] By arranging two aggregate mesh boxes 4 on the left and right, when the left aggregate mesh box 4 is full, the waterproof oil cylinder 24 drives the rotating plate 23 to adjust the angle, so that the framework falling in the material guiding channel slides into the right aggregate mesh box 4. After the left aggregate mesh box 4 is completely cooled, it is lifted by a crane, and then used in a left-right cycle in turn.

[0022] Refer to Figure 3 and Figure 4 , in order to enable the aggregate mesh box 4 to be lifted and positioned accurately and flexibly in the water storage tank 2, a sliding groove 5 is arranged on the inner wall of the water storage tank 2. Sliding blocks are arranged at the positions of the aggregate mesh box 4 corresponding to the sliding groove 5. Suspension rings are fixed at the four corners of the top end of the aggregate mesh box 4.

[0023] The implementation principle of a quenching device for producing a crawler iron tooth framework in an embodiment of the present application is as follows:

[0024] The iron-toothed skeleton is heated in the intermediate-frequency quenching furnace 1 in sequence. After heating, it is sent above the material guiding channel by the chain conveyor belt 3 and then drops into the water. Under the action of its own gravity, it slides along multiple baffles 22 until it slides into the aggregate mesh box 4. During this process, the surface of the skeleton can be completely wrapped and covered by water due to the blocking of the multi-layer baffles 22, and its surface can be quickly cooled. After the surface is cooled, the skeleton slowly undergoes internal cooling in the aggregate mesh box 4, and the overall cooling effect is good, greatly improving the quenching effect.

[0025] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
