Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, a synchronous rotating electrode powder making machine includes a motor 1, a coupling 2, a main shaft 3, an atomizing chamber 17, and a first rotating disc 4, a second rotating disc 10, Tungsten pole 6 and anode metal rod 7. The output shaft of the motor 1 is connected with one end of the main shaft 3 through a coupling 2 . The other end of the main shaft 3 passes through the atomization chamber 17 and is connected with the first rotating disc 4, on which the spline shaft 8 is arranged, and on the second rotating disc 10, the spline shaft 8 is arranged. The opposite spline shaft sleeve 9, the spline shaft 8 is connected with the spline shaft sleeve 9 to keep the first rotating disk 4 and the second rotating disk 10 rotating synchronously. A tungsten pole 6 is arranged at the non-center position of the first rotating disk 4, and an a...

The invention discloses a synchronous rotation electrode powder making machine, which comprises a motor, a coupler and a main shaft. An output shaft of the motor is connected with one end of the main shaft through the coupler. The synchronous rotation electrode flour mill is characterized in also comprising an atomizing chamber, a first rotary disc, a second rotary disc, a tungsten electrode and an anode metal rod; the first rotary disc, the second rotary disc, the tungsten electrode and the anode metal rod are arranged in the atomizing chamber; the other end of the main shaft is connected with the first rotary disc through the atomizing chamber; the tungsten electrode is arranged at non-center position of the first rotary disc; the second rotary disc keeps synchronous rotation with the first rotary disc; the anode metal rod is arranged at non-center position of the second rotary disc; the anode metal rod is opposite to the tungsten electrode; the tungsten electrode is connected with a negative electrode of a power supply; the anode metal rod is connected with a positive electrode of the power supply; and the atomizing chamber is connected with a vacuum pumping device. In the invention, the problems that the finished product ratio of spherical metal powder is low and the particle size of the powder is bigger are solved; and the synchronous rotation electrode powder making machine which can obtain spherical metal powder with tiny particle size under common rotating speed is provided.
Description
technical field [0001] The invention relates to the technical field of spherical metal powder preparation, in particular to a synchronous rotating electrode powder making machine. Background technique [0002] Nowadays, the centrifugal atomization method is one of the preparation methods of spherical metal powder, which can keep the chemical properties of the metal unchanged, and at the same time, the yield of spherical metal powder and the cleanliness of the finished product are relatively high. The centrifugal atomization method relies on a special power supply to generate an arc between the anode and the cathode, the end face of the anode rod is melted, and the anode rotates around its axis at high speed, resulting in a strong centrifugal force, and the anode metal melted by the arc heat is formed in the form of small droplets Throw it out, cool it rapidly under a certain pressure of protective gas environment, and solidify into a spherical powder. However, since the ano...
