The powder produced by this technology is highly favored in the field of 3D printing due to its advantages of high sphericity, low impurity content and controllable particle size. Its basic principle is to use non-contact surface induction heating to melt the metal bar. The liquid metal falls vertically into the center of the annular inert gas nozzle, and the high-speed gas is used to break the metal liquid flow into fine droplets, which are finally solidified in the atomization tower to form powder.

[0032] A synchronization groove 416 is provided on the outer wall of the output shaft 402, and two telescopic grooves 417 are provided on the inner wall of the second double-headed bevel gear 413.

[0033] Working principle: Place the thicker end of the bar 101 inside the positioning groove 203 at the top of the mounting seat 201; The first motor 303 drives one of the first rotating shafts 302 to rotate, and then transmits power to the connecting shaft 305 through the second bevel gear 307, so that it rotates, and drives the other first rotating shaft 302 to rotate through the first bevel gear 306. The two first rotating shafts 302 respectively drive the corresponding swing arms 308 to rotate; When the swing arm 308 rotates, the driving screw 313 rotates synchronously, so that the clamping block 316 on the screw 313 is clamped into the clamping groove 102 on the surface of the bar 101. At this time, the bar 101 can be installed on the mounting seat 201. Subsequently, the mounting seat 201 is installed on the housing of the vacuum electrode induction atomization device; The block 316 squeezes the rod 101, causing the thicker end of the rod 101 to slide into the positioning groove 203, and the end of the rod 101 squeezes the pressure plate 206, which drives the first slider 207 to slide downward along the first slide bar 209, and the first spring 210 is stretched. At the same time, the sliding of the pressure plate 206 squeezes the rubber airbag 204. After the rubber airbag 204 is squeezed, the air inside is compressed and introduced into the inside of the sealing ring 202 through the air guide tube 205. In this process, the outer wall of the sealing ring 202 expands and fits tightly on the inner wall of the shell of the vacuum electrode induction atomization device, thereby improving the sealing performance of the installation of the mounting seat 201; During the rotation of the swing arm 308, the electric push rod 412 remains in a retracted state, the synchronization block 419 inside the second double-headed bevel gear 413 slides out of the synchronization groove 416, and the second double-headed bevel gear 413 maintains a meshing relationship with the fifth bevel gear 411 at the lower end of the second rotating shaft 410. As the swing arm 308 continues to rotate, the first support plate 404 and the second support plate 423 are driven to rotate synchronously. At the same time, the swing arm 308 drives the worm 405 to rotate around the first rotating shaft 302. During this process, the fifth bevel gear 411 drives the second double-headed bevel gear 413 to rotate through meshing. The second double-headed bevel gear 413 is rotating, while the output shaft 402 does not rotate. When the end of the clamping block 316 moves to the bottom of the clamping groove 102, the end of the screw rod 313 corresponds to the clamping hole 103. At this time, the electric push rod 412 begins to extend to push the connecting plate 414 to move, and the movement of the connecting plate 414 drives the second double-headed bevel gear 413 to slide along the outer wall of the output shaft 402, so that the second double-headed bevel gear 413 gradually disengages from the meshing state with the fifth bevel gear 411. At the same time, under the elastic force of the second spring 422, the synchronization block 419 in the second double-headed bevel gear 413 can be inserted into the synchronization groove 416 on the output shaft 402; The second motor 401 drives the two output shafts 402 to rotate synchronously through the synchronous wheel 403, and drives the fourth bevel gear 407 to rotate through the synchronous block 419. The rotation of the fourth bevel gear 407 further drives the worm 405 to rotate, and drives the worm wheel 317 to rotate through the worm 405, and drives the limit block 312 to rotate through the mounting sleeve 311. The rotation of the limit block 312 causes the screw 313 to rotate and move spirally along the inner wall of the threaded sleeve 310. As the screw 313 rotates further, its end gradually inserts into the clamping hole 103 of the bar 101, thereby further fixing the bar 101, so that the bar 101 is firmly installed in the mounting seat 201; The rotation of the worm 405 drives the third bevel gear 406 meshing with it to rotate, and the third bevel gear 406 drives the first double-headed bevel gear 409 to rotate, and the rotation of the first double-headed bevel gear 409 drives the fifth bevel gear 411, so that the fifth bevel gear 411 and the second double-headed bevel gear 413 rotate synchronously; When the second motor 401 drives the output shaft 402 to rotate, the rotational force of the output shaft 402 is transmitted to the second double-headed bevel gear 413, thereby driving the fourth bevel gear 407 to start rotating. At this time, the fifth bevel gear 411 at the lower end of the second rotating shaft 410 can rotate synchronously; When the second double-headed bevel gear 413 is meshed with the fifth bevel gear 411, the swing arm 308 rotates around the first rotating shaft 302, and the fifth bevel gear 411 at the lower end of the second rotating shaft 410 can drive the second double-headed bevel gear 413 to rotate. At this time, the electric push rod 412 adjusts the position of the second double-headed bevel gear 413 through the connecting plate 414 to ensure that it can always maintain a correct meshing relationship with the fourth bevel gear 407 and the fifth bevel gear 411, thereby avoiding collision between the convex teeth of the bevel gears.
