[0023] When in use, after the shaft assembly 4 is sintered and formed by the MIM process, the shaft assembly 4 is placed on the upper end surface of the positioning support block 204, the power is turned on, and the hydraulic cylinder 103 is started, so that the hydraulic cylinder 103 drives the heat conduction plate 209 and the second shaping strip 207 to move downward and contact with the upper end surface of the shaft assembly 4 through the lower pressing block 202 under the support of the mounting frame 102, and at the same time, the lower pressing block 202 drives the transmission angle plate 105 to slide down in the redundant groove provided on the inner side of the connecting slider 106 during the downward movement, and then the transmission angle plate 105 can press down the connecting slider 106 when it moves to the bottom of the redundant groove, and then the connecting slider 106 is guided by the guide slide 104 and drives the central positioning column 203 to move upward on the inner side of the positioning support block 204 through the curved connecting rod 107; At this time, the center positioning column 203 can penetrate the middle part of the rotating shaft assembly 4 and be plugged into the inner side of the bottom end of the lower pressing block 202, and then the bottom block 201, the lower pressing block 202 and the center positioning column 203 can be installed to position and clamp the rotating shaft assembly 4, and the first shaping strip 206 and the second shaping strip 207 can be used to perform contour positioning on the rotating part of the rotating shaft assembly 4.

Specifically, the inner side of the liquid storage tank 301 is filled with coolant, and the bottom ends of the guide pipe 306 and the first liquid infusion elbow 307 are fixed with a gear pump, so that the gear pump can synchronously transport the coolant to the inner sides of the two cooling bins 208 through the guide pipe 306, the first liquid infusion elbow 307 and the second liquid infusion elbow 308, and then the cooling bin 208 can quickly and fully cool the shaped shaft assembly 4 through the heat conduction of the heat conducting plate 209; At the same time, the fan box 305 can continuously dissipate the coolant after cooling the shaft assembly 4 and returning through multiple heat dissipation fins 304, thereby ensuring the stable shaping of the shaft assembly 4. The second infusion bend 308 is slidably connected to the guide tube 306, so that the second infusion bend 308 is connected to the guide tube 306 before and after shaping to avoid leakage of coolant. When the lower pressing block 202 is reset, the lower pressing block 202 is separated from the positioning support block 204 and can drive the center positioning column 203 to move down and reset through the transmission angle plate 105, the connecting slider 106 and the curved connecting rod 107, thereby facilitating the unloading of the shaft assembly 4.
