[0026] In Figure 1 and Figure 2 Among them, a liquid extraction pump 401 is installed on the right side of the processing table 1. A three-way joint 402 is installed at the water outlet of the liquid extraction pump 401. A first conduit 403 is installed at the top of the three-way joint 402. A second conduit 404 is installed at the left end of the three-way joint 402. Corrugated hoses 405 are installed at the opposite ends of the first conduit 403 and the second conduit 404. Spray heads 406 are installed at the tops of the chucks of the two telescopic clamps 2. The liquid extraction pump 401, the three-way joint 402, the first conduit 403, the second conduit 404, and the corrugated hose 405 are used to form a structure for delivering coolant to the two spray heads 406, so as to facilitate cooling the heated crank member.

[0027] In Figure 3 and Figure 4 Among them, a cooling tank 407 is opened on the inner bottom wall of the processing table 1. A microplate 408 is installed at the opening of the cooling tank 407, facilitating the coolant to flow back into the cooling tank 407 through the holes on the microplate 408, reducing unnecessary waste.

[0028] In Figure 3 and Figure 4 Among them, a connection hole 409 is opened between the left side of the processing table 1 and the inner left wall of the cooling tank 407. A sealed heat-conducting plate 410 is installed inside the connection hole 409. A semiconductor refrigerator 411 is connected to the left side of the sealed heat-conducting plate 410, used to cool the coolant inside the cooling tank 407, so as to keep the temperature of the coolant low and facilitate cooling.

[0029] It should be noted that this part aims to provide background or context for the embodiments described in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, both fixed and movable installations are determined according to the actual application methods. To ensure the compatibility of the equipment, the operating means adopted are consistent with the parameters of market instruments. The descriptions here are not admitted to be prior art just because they are included in this part.

[0030] During implementation, the following steps are carried out for operation:

[0031] 1) First, use the telescopic clamp 2 to limit the workpiece to be processed directly below the press head cylinder 3, and then start the press head cylinder 3 for pressing;

[0032] 2) Then, start the liquid extraction pump 401 and turn on the nozzle 406, extract the coolant inside the cooling tank 407, and supply it to the two nozzles 406 through the three-way joint 402, the first conduit 403, the second conduit 404, and the corrugated hose 405;

[0034] In summary, for this crank heat treatment device, by setting components such as the liquid extraction pump 401 and the nozzle 406, the nozzle 406 is used to directly spray liquid on the crank member with high heat dissipation to cool it down. There is no need for the staff to move and change the position of the crank member. After the cooling is completed, the telescopic fixture 2 can be separated and the crank member can be directly taken out, which further speeds up the efficiency of replacing the crank member, facilitates the operation and use of the user. At the same time, with the design of the three-way joint 402, the three-way joint 402 can split the coolant, so that both nozzles 406 can spray the coolant, thereby improving the cooling efficiency and the coverage range, and further facilitating the use of the user.

[0035] Moreover, the stretchability of the corrugated hose 405 facilitates the stability of the connection between the nozzle 406 and the chuck of the telescopic fixture 2 when the nozzle 406 is driven to move by the chuck of the telescopic fixture 2, ensuring the effective delivery of the coolant. Through the setting of the microporous plate 408, the coolant after absorbing heat can flow back into the cooling tank 407, avoiding waste and reducing the cost in use. At the same time, with the design of the sealed heat-conducting plate 410 and the semiconductor cooler 411, it is convenient for the user to cool the liquid inside the cooling tank 407, thereby ensuring that the low temperature of the coolant is beneficial to the effect of the cooling operation, further facilitating the use of the user, and solving the problems in the comparative document that it is necessary to frequently supplement low-temperature water liquid, manually adjust the position of the crank, and the operations of processing or cooling are laborious and not conducive to use.
