Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1-Figure 3A high-temperature alloy rod end face pre-cooling device includes a base 1, the four corners of the base 1 are connected to columns 2, the columns 2 are connected to a top plate 3, and a hydraulic cylinder 4 is installed on the top plate 3; a supporting mechanism 5 for supporting the rod is installed on the base 1, and the telescopic end of the hydraulic cylinder 4 is connected to a clamping mechanism 6 for pressing the rod tightly against the supporting mechanism 5, and Z-shaped mounting plates 7 are connected on both sides of the clamping mechanism 6, and a water spraying mechanism 8 for spraying water to the end face of the rod is installed on the mounting plate 7.

[0021] Specifically, the support mechanism 5 comprises a support platform 51 and support plates 52 connected to both ends of the support platform. The top of the support plate 52 is provided with a first arc-shaped groove 53. The clamping mechanism 6 comprises a lifting platform 61 connected to the telescopic end of the hydraulic cylinder and a pressure plate 62 connected to both ends of the lifting platform. The bottom of the pressure plate 62 is provided with a second arc-shaped groove 63 that mates with the first groove. The red-hot bar is placed in the first groove 53 of the support plate 52 via a lifting device. The hydraulic cylinder 4 is then controlled to extend, driving the lifting platform 61 downward. The second groove 63 on the pressure plate 62 compresses the bar to facilitate subsequent end-face cooling.

[0022] The water spray mechanism 8 includes a first pipe 81 rotatably connected to the mounting plate. The end of the first pipe 81 near the support mechanism 5 is connected to a disk 82. Disk 82 has a cavity within it, and the first pipe 81 communicates with the cavity. The side of disk 82 near the support mechanism 5 is connected to a plurality of nozzles 83 that communicate with the cavity. After the support plate 52 and the pressure plate 62 are docked, disk 82 aligns with the first groove 53 and the second groove 63. The end of the first pipe 81 away from the disk is connected to a second pipe 85 via a rotary joint 84. The second pipe 85 is connected to a flange 86 that allows it to be connected to an external water source. Once the bar is secured, water is delivered from an external water source through the second pipe 85 and the first pipe 81 to the disk 82. The nozzles 83 then spray water onto the end face of the bar, pre-cooling the end face.

[0023] The working principle of this embodiment is:

[0024] The rod is placed on the supporting mechanism through the lifting device, and the rod is pressed against the supporting mechanism through the pressing mechanism. Then, water is sprayed to the end face of the rod through the water spraying mechanism on the two mounting plates, so that the end face of the rod can be pre-cooled. After the pre-cooling is completed, the rod is placed in the water pool for quenching through the lifting device, which can effectively prevent the end face of the rod from cracking due to the rapid drop in temperature.
