[0019] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] Reference Figs. 1-3As shown, this utility model provides a bolt production circulating cooling device, including a frame 1, two thread rolling rollers 1.1 rotatably connected to the frame 1, a nozzle 1.2 fixedly connected to the frame 1, a plurality of spray pipes 1.21 rotatably connected to the nozzle 1.2, an elastic element 1.22 rotatably connected between the spray pipes 1.21 and the nozzle 1.2, and a fan blade 1.24 rotatably connected to the bottom end of the nozzle 1.2.

[0021] Among them, a turbine 1.23 is rotatably connected to the bottom end of the nozzle 1.2, and the turbine 1.23 is coaxially and fixedly connected to the fan blade 1.24.

[0022] The elastic element 1.22 includes a sleeve 1.221, a telescopic rod 1.222 is slidably connected inside the sleeve 1.221, one end of the sleeve 1.221 is hinged to the nozzle 1.2, and one end of the telescopic rod 1.222 is hinged to the nozzle 1.2.

[0023] A spring 1.223 is fixedly connected inside the sleeve 1.221, and one end of the spring 1.223 is fixedly connected to the telescopic rod 1.222.

[0024] Specifically, two thread rolling rollers 1.1 are rotatably connected to the frame 1. The two thread rolling rollers are driven by a motor. A nozzle 1.2 is fixedly connected to the upper end of the frame 1. In this example, the driving is mainly achieved by changing the water pressure of the nozzle 1.2 by changing the flow rate of the coolant flowing into the nozzle. There are two main methods: First, if the pump head remains unchanged, a solenoid valve is connected through the nozzle 1.2. By adjusting the size of the solenoid valve opening, the flow rate of the coolant in the nozzle 1.2 is changed, thereby changing the angle of the nozzle 1.2. Second, the flow rate in the nozzle 1.2 is adjusted by changing the pump head.

[0025] A turbine 1.23 is rotatably connected to the bottom of the inner wall of the nozzle 1.2. A fan blade 1.24 is coaxially fixedly connected to the turbine 1.23. The fan blade 1.24 is located outside the nozzle 1.2. Multiple nozzles 1.21 are rotatably connected to the outer circumference of the nozzle 1.2. Multiple spray holes are opened on the nozzles 1.21. An elastic element 1.22 is hinged between the nozzles 1.21 and the nozzle 1.2. The elastic element 1.22 includes a sleeve 1.221 with one end hinged to the nozzle 1.21. A telescopic rod 1.222 is slidably connected inside the sleeve 1.221. The other end of the telescopic rod 1.222 is hinged to the nozzle 1.2. A spring 1.223 is fixedly connected inside the sleeve 1.221. One end of the spring 1.223 is fixedly connected to the corresponding telescopic rod 1.222.

[0026] In use, the coolant flowing into the nozzle 1.2 is changed by the solenoid valve, which causes the telescopic rod 1.222 to move within the sleeve 1.221, compressing the spring 1.223 within the sleeve 1.221 and changing the angle of each spray pipe. When the coolant flows through the turbine 1.23, the turbine 1.23 drives the fan blade 1.24 to rotate, which in turn causes the fan blade 1.24 to rotate during the spraying process. Air cooling is also provided during the cooling process.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
