Compared with the metal powder preparation device in the prior art, the metal powder is easy to make the metal ingot shake during the rubbing process, which makes it easy to rub out large particles of metal powder. The rubbing operation of the present invention is relatively stable and the rubbing is uniform.

[0026] In a further embodiment of the present invention, Figure 1-3 As shown, the swing drive assembly includes a driven turntable 103 rotatably arranged at the center of the triangle plate 1, a crankshaft 102 is arranged on the axis of the driven turntable 103, a fixed shaft rod 101 is arranged at the bottom end of the triangle plate 1, a slot frame 4 is rotatably arranged at the top end of the fixed shaft rod 101, the crankshaft 102 is inserted into the wire groove in the middle of the slot frame 4, a movable shaft rod 301 is arranged on the side wall of the slider 3, the movable shaft rod 301 is inserted into the wire groove in the middle of the slot frame 4, and the driven turntable 103 is connected to the power assembly.

[0027] In this embodiment, the crankshaft 102 on the driven turntable 103 drives the slider 3 and the cantilever arm 5 at its top to move back and forth through the slot frame 4, and then the grinding box 6 and the grinding liner 601 inside it are pushed back and forth along the guide rail 2 to perform powder rubbing operation at the end of the metal bar ingot 703.

[0030] In a further embodiment of the present invention, Figure 5-7 As shown, the grinding liner 601 is divided into two halves, the two halves of the grinding liner 601 are connected by countersunk bolts, and a heat insulation sheet is arranged between the two halves of the grinding liner 601. A water cooling mechanism is arranged inside the grinding liner 601.

[0031] In this embodiment, when the temperature of one half of the grinding liner 601 rises to a certain temperature, the grinding liner 601 is twisted 180 degrees to allow the other half of the grinding liner 601 to reach the powder rubbing station, thereby preventing the grinding liner 601 from being too hot for continuous powder rubbing.

[0032] In a further embodiment of the present invention, Figure 5-7 As shown, the water cooling mechanism includes a water chamber inside the grinding liner 601, and the shape of the water chamber inside the grinding liner 601 is semi-cylindrical. The ends of the left and right halves of the grinding liner 601 are each provided with two water holes 602. A water pipe interface 802 is provided at the port of the water hole 602. A towing hose 8 is connected to the outside of the water pipe interface 802. The towing hose 8 is connected to the input pipe of the cold liquid pump 801, and the output pipe of the cold liquid pump 801 and another towing hose 8 are connected to the cold liquid tank.

[0033] In this embodiment, the half of the grinding liner 601 facing away from the processing position begins to cool down, and the cold liquid pump 801 injects new cold liquid into the grinding liner 601 through the water pipe interface 802. The original hot liquid in the grinding liner 601 will also be discharged, and the specific heat capacity of the water is greater than that of the grinding liner 601 made of hard metal. The water can absorb more heat generated by the processing process. Compared with the cooling method of the prior art, the previous cooling would be done by direct watering, but the water would increase the corrosion rate of the metal powder.

[0034] In a further embodiment of the present invention, Figure 1-6 As shown, the ejector mechanism includes a guide groove on the side wall of the charging box 7, one side of the U-shaped steel fork 902 slides and inserts into the guide groove, and the end of the other side of the U-shaped steel fork 902 abuts against the end face of the metal strip ingot 703, and the U-shaped steel fork 902 is connected to the linkage assembly.

[0035] In this embodiment, when the U-shaped steel fork 902 is inserted into the guide groove, the other side of the U-shaped steel fork 902 will push the metal bar ingot 703 out.

[0036] In a further embodiment of the present invention, Figure 1-5 As shown, the linkage assembly includes a threaded rod 9 on the axis of the driven turntable 103 , a nut block 901 is sleeved on the outer side of the threaded rod 9 , and a U-shaped steel fork 902 is fixed on the side wall of the nut block 901 .

[0037] In this embodiment, the threaded rod 9 at the axis of the driven turntable 103 drives the nut block 901 and the U-shaped steel fork 902 on its outer side to move backward, thereby achieving a linkage effect.

[0038] In a further embodiment of the present invention, Figure 1-6As shown, the outer wall of the metal strip ingot 703 is attached to the inner wall of the circular channel, and the circular channel and the semicircular groove on the outer side of the charging liner 701 are ground and polished.

[0039] In this embodiment, after being ground and polished, the circular channel and the charging liner 701 can have a smaller friction with the metal bar ingot 703, thereby preventing the metal bar ingot 703 from being stuck.

[0040] Working principle: put two metal strip ingots 703 of different metal materials to be processed into the semicircular groove outside the charging liner 701, twist the charging liner 701 and the metal strip ingot 703 outside it downward, and the ejector mechanism ejects the metal strip ingot 703 at a uniform speed along a straight line, and the grinding liner 601 moves back and forth to rub the end of the metal strip ingot 703 for powder, which will be evenly mixed in the process of rubbing the powder, and the metal strip ingot 703 will not vibrate in the process of being ejected, achieving the effect of efficient rubbing and mixing. Compared with the metal powder preparation device of the prior art, the previous metal powder The metal ingot is easily shaken during the powder rubbing process, which makes it easy to rub out large particles of metal powder. The powder rubbing operation of the present invention is relatively stable and the powder rubbing is uniform. The crankshaft 102 on the driven turntable 103 drives the slider 3 and the beam arm 5 at its top to move back and forth through the notch frame 4, and then the grinding box 6 and the grinding liner 601 inside it are pushed back and forth along the guide rail 2 to the end of the metal strip ingot 703 for powder rubbing. The stepper motor 105 drives the driven turntable 103 to rotate through the driving turntable 104 and the belt 106. If the distortion of the driven turntable 103 needs to be adjusted, replace the driving turntable with a smaller diameter. 104, when the temperature of one half of the grinding liner 601 rises to a certain temperature, the grinding liner 601 is twisted 180 degrees to allow the other half of the grinding liner 601 to reach the powder rubbing station, which can prevent the grinding liner 601 from being too hot due to continuous powder rubbing. The half of the grinding liner 601 facing away from the processing position begins to cool down, and the cold liquid pump 801 injects new cold liquid into the grinding liner 601 through the water pipe interface 802. The original hot liquid in the grinding liner 601 will also be discharged, and the specific heat capacity of the water is greater than that of the hard metal grinding liner 601, and the water can absorb more of the processing process. The heat generated is compared with the cooling method of the prior art. In the past, cooling would be done by direct watering, but water would increase the corrosion rate of metal powder. When the U-shaped steel fork 902 is inserted into the guide groove, the other side of the U-shaped steel fork 902 will push the metal bar ingot 703 out, and the threaded rod 9 on the axis of the driven turntable 103 drives the nut block 901 and the U-shaped steel fork 902 on its outside to push backward, achieving a linkage effect. After grinding and polishing, the circular channel and the loading liner 701 can have less friction with the metal bar ingot 703 to prevent the metal bar ingot 703 from being stuck.
