[0002] In the production process of fasteners, heat treatment is a crucial process, which directly affects the mechanical properties, service life and reliability of fasteners. With the continuous development of modern industry, the quality requirements for fasteners are getting higher and higher, and traditional heat treatment equipment is gradually difficult to meet the market demand.

[0003] There are certain limitations in the cooling treatment effect of fastener heat treatment equipment in the current technology. For example, traditional fastener heat treatment equipment needs to let the materials stand still in the cooling box for temperature reduction after quenching. Common cooling boxes are generally static and cannot flow, so that in the case of multiple cooling operations, the liquid temperature rises relatively fast, thus affecting the cooling effect of the materials. At the same time, traditional heat treatment equipment often has a low degree of automation and is inconvenient to use.

[0004] Therefore, a heat treatment equipment for fastener production is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat treatment equipment for fastener production to solve the problems raised in the above background technique.

One end of the water inlet pipe 6 is connected to the inside of the second cooling box 3 in a penetrating manner, and the other ends of the two water outlet pipes 8 are both connected to the inside of the first cooling box 4 in a penetrating manner. Through the second cooling box 3, the water outlet pipes 8 and the first cooling box 4 that are in communication, a circulation of the cooling liquid is formed.

[0019] As Figure 2 shown, during the cooling process, to further improve the cooling effect, the transmission mechanism includes a driven wheel 11, one side of the driven wheel 11 is installed at one end of the drainage roller 10, a driving wheel 13 is arranged below the driven wheel 11, a gear chain 12 is jointly rotatably connected to one side of the driven wheel 11 and the driving wheel 13, a driving device 14 is installed on one side of the driving wheel 13, and one side of the driving device 14 is installed on the first cooling box 4. The driving device 14 drives the driving wheel 13 to rotate. Here, the driving device 14 belongs to the prior art and will not be described here. The driving wheel 13 drives the driven wheel 11 to rotate through the gear chain 12, so that the drainage roller 10 rotates inside the two fixing seats 9. The rotation of the drainage roller 10 helps to improve the cooling effect and cooling efficiency. At the same time, the water pump 5 works, and the cooling water in the second cooling box 3 is pumped out through the water inlet pipe 6 and transported to the first cooling box 4 through the sub-control valve 7 and the water outlet pipes 8 to ensure the supply and circulation of the cooling water.

[0020] As Figure 3 and 4As shown in the figure, the lifting mechanism includes a U-shaped table 17, which is installed on the electric slider 16. A winding roller 18 is rotatably installed inside the U-shaped table 17. One end of the winding roller 18 is equipped with a winding motor 19, and the winding motor 19 is installed on the U-shaped table 17. A chain 20 is installed on the outer wall of the winding roller 18, and a quenching box 21 is hung at the other end of the chain 20. The quenching box 21 is arranged inside the quenching device 22. After quenching is completed, the quenching box 21 is lifted by the lifting mechanism and moved above the first cooling box 4, and the quenching box 21 is placed into the first cooling box 4 for cooling.

[0021] As Figure 3 and 4 shown in the figure, two limit plates 241 are installed on the U-shaped table 17. Fixed rods 231 are slidably installed inside the two limit plates 241. The lower ends of the two fixed rods 231 are installed on the quenching box 21. Through the arrangement of the fixed rods 231 and the limit plates 241, during the process of controlling the winding roller 18 to pull the chain 20 and the quenching box 21 to rise, in order to prevent the quenching box 21 from shaking, the upward moving fixed rods 231 are limited by the limit plates 241, so as to drive the quenching box 21 to move vertically up and down, improving the stability of the equipment operation.

[0022] The working principle is as follows: When the present invention is actually used, first, the fasteners to be heat-treated are placed into the quenching box 21. Then, the electric slide rail 15 is started, and the electric slider 16 slides inside the electric slide rail 15, driving the U-shaped table 17 to move to a suitable position. At this time, the winding motor 19 in the lifting mechanism is started, driving the winding roller 18 to rotate. The winding roller 18 winds the chain 20, thus lifting the quenching box 21. Then, the electric slider 16 moves, moving the quenching box 21 above the quenching device 22 and lowering the quenching box 21 to make it enter the quenching device 22 for quenching treatment; After quenching is completed, the quenching box 21 is lifted again by the lifting mechanism and moved above the first cooling box 4, and the quenching box 21 is placed into the first cooling box 4 for cooling. During the cooling process, the transmission mechanism works. The driving device 14 drives the driving wheel 13 to rotate, and the driving wheel 13 drives the driven wheel 11 to rotate through the gear chain 12, so that the drainage roller 10 rotates inside the two fixed seats 9. The rotation of the drainage roller 10 helps to improve the cooling effect and cooling efficiency. At the same time, the water pump 5 works, pumping out the cooling water in the second cooling box 3 through the water inlet pipe 6, and delivering it to the first cooling box 4 through the sub-control valve 7 and the water outlet pipe 8 to ensure the supply of cooling water. The coordinated action of the electric slider 16 and the lifting mechanism realizes the precise movement and positioning of the quenching box 21. The quenching device 22 completes the quenching treatment of the fasteners. The cooling system composed of the first cooling box 4, the second cooling box 3 and the water pump 5 ensures the cooling effect of the fasteners. The drainage roller 10 in the transmission mechanism improves the cooling efficiency. Through the close cooperation of each component, this equipment can efficiently and accurately complete the production heat treatment process of the fasteners.

[0023] Example 2: As Figure 1 and 2 shown, to further improve the production quality, an opening 23 is provided at the top of the first cooling tank 4, and a filter plate 24 is inserted into the opening 23. Through the settings of the opening 23 and the filter plate 24, the water flow rate is further accelerated. At the same time, the filter plate 24 filters the impurities doped in the first cooling tank 4 to reduce the attachment of impurities to the material during cooling.

[0024] As Figure 3 and 5 shown, a discharge port 25 is provided at the bottom of the quenching tank 21. A rotating plate 26 is rotatably installed inside the discharge port 25. A stopper 27 is provided at the bottom of the rotating plate 26. A rotating table 28 is rotatably installed on one side of the stopper 27, and the rotating table 28 is installed on the quenching tank 21. After cooling is completed, the quenching tank 21 is lifted and moved to a designated position. The discharge port 25 is opened, and the rotating plate 26 is rotated to make the fasteners fall from the discharge port 25. The stopper 27 and the rotating table 28 are used to limit the rotation range of the rotating plate 26, facilitating later centralized collection.
