Description

Technical Field

[0001] The invention relates to the field of metal powder processing, in particular to a vacuum atomization powder making automation equipment. Background Art

[0002] The powders prepared by gas atomization have small particle size, high sphericity, low oxygen content, good fluidity, and can be produced on a large scale in an industrialized manner. After continuous development, gas atomization powder making technology has become the main method for producing high-performance spherical metal and alloy powders;

[0003] Gas atomization technology originated in the 1920s, when American Hall.EJ first used air to atomize copper alloy powder. Early atomization technology used a non-restricted (also called free-fall) atomizing nozzle, which is characterized by a long distance between the gas outlet and the plasma metal liquid. The free-fall nozzle is simple in design, but has poor atomization ability and is only suitable for the production of alloy powders with larger particle sizes. For metals and alloys with high chemical activity, free-fall atomizing nozzles are still a good choice, because the metal liquid falls freely during the atomization process, avoiding direct contact with the tundish and the guide tube, so that the alloy composition of the molten metal will not be affected;

[0004] Due to the limitations of hardware equipment and crucibles, the heating temperature of vacuum induction melting can only reach 1500-1600℃ at most. And due to the influence of the use of ceramic crucibles and flow nozzles, impurities will be introduced into the alloy melt, affecting the purity of the prepared metal powder;

DETAILED DESCRIPTION

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-11 As shown, a vacuum atomization powder making automation equipment.

[0046] A vacuum atomization powder making automation equipment, including a smelting furnace diagram, 1, a support frame 2, a straightening box 3, a plasma torch 4 and a collecting box 5, wherein the smelting furnace diagram, 1 is arranged on the support frame 2, a feeding device is arranged on the support frame 2, the straightening box 3 is located at the end of 1 in the smelting furnace diagram, the plasma torch 4 is installed on 1 in the smelting furnace diagram through an angle adjustment structure, the collecting box 5 is located at the bottom of 1 in the smelting furnace diagram, a straightening structure is arranged inside the straightening box 3, a material pouring structure is arranged on 1 in the smelting furnace diagram, a gas emission purification device is connected to 1 in the smelting furnace diagram, and a collecting structure is arranged in 1 in the smelting furnace diagram;

[0047] It should be noted that the technical solution is to push the wire raw material through the feeding structure. After the wire enters the straightening box 3, it is straightened by the straightening structure. Then the wire raw material enters the smelting furnace 1, and the plasma torch 4 is adjusted by the angle adjustment structure so that the ignition point of the plasma torch 4 is located at the same position. The plasma torch 4 will melt the wire raw material, so that the wire raw material becomes metal powder and falls into the smelting furnace 1, and then is led out to the collecting structure by the pouring structure, and the smelted flue gas is discharged through the gas emission purification equipment.

[0048] The angle adjustment structure is composed of four linkage shafts 6, two sets of adjustment parts with identical structures and a secondary cooler 7, one of which includes: an elastic telescopic member 8, a shaft plate 9, a rotating column, a connecting seat 10, a pair of connecting rods 11, four gears 12, and a feed motor 13;

[0049] There are four plasma torches, which are respectively arranged on the upper and lower sides of the secondary cooler 7. After the material sent out by the straightening structure is heated by two of the plasma torches, the material flows out after entering the secondary cooler 7 and is heated by the other two plasma torches.

[0050] The elastic telescopic member 8 is placed on the wall of the smelting furnace, the shaft plate 9 is installed at the front end of the elastic telescopic member 8, the connecting seat 10 is installed on the shaft plate 9 through the rotating shaft, the four linkage shafts 6 are arranged in sequence, and the gears 12 are fixed respectively, and the feed motor 13 drives one of the linkage shafts 6;

[0051] The pair of connecting rods 11 are respectively mounted on the upper and lower opposite linkage shafts 6, and have an angle greater than 30° with the axis of the linkage shaft 6. The connecting seat 10 is fixed to the plasma torch, and the other end of the connecting rod 11 is movably connected to the outer wall of the plasma torch.

[0052] It should be noted that this technical solution is to increase the powder making effect. After the metal powder is initially heated and melted, it will be cooled by the secondary cooler 7, and then heated by another two plasma torches to complete sufficient powder making.

[0053] Specifically, in order to achieve accurate spraying of the two gun bodies of the plasma torch chamber, an adjustment structure is used to achieve precise adjustment. At the same time, this technical solution uses a driving motor to adjust the four plasma torches, thereby reducing energy consumption and adopting an ingenious transmission structure;

[0054] Specifically, when the feed motor 13 drives one of the linkage shafts 6, the linkage shafts 6 mesh with each other through the four gears 12. After the meshing is completed, the four connecting rods 11 on the four linkage shafts 6 all move. Since the four connecting rods 11 are pin-connected to the plasma torch gun, one end of the plasma torch gun is connected to the elastic telescopic member 8 through a rotating column, and the connecting rod 11 has an angle with the linkage shaft 6, the linkage shaft 6 rotates with the connecting rod 11 at a certain angle, which will realize the movement of the gun head of the plasma torch chamber.

[0055] Specifically, the secondary cooler 7 comprises: a cooling groove 14, and a cooling channel 15 which is repeatedly inclined and integrally connected;

[0056] The material flows out after passing through the cooling channel 15;

[0057] The four linkage shafts 6 penetrate the cooling groove 14, and the penetration portion is located behind the multiple cooling channels 15 and is connected with four gears 12 and a pair of connecting rods 11 in another adjustment part;

[0058] It should be noted that a cooling channel 15 is provided inside the cooling tank 14, a cavity structure is adopted in the cooling channel 15 and the cooling tank 14, and a cooling medium is injected, and the cooling medium is circulated and cooled by an externally connected cooling device. When the material enters the cooling channel 15 from the cooling tank 14, rapid cooling can be achieved. In order to increase the uniformity of cooling, the cooling through groove is repeatedly tilted and connected in one piece.

[0059] Specifically, the straightening structure comprises: a pair of chain conveyors 16 with completely identical structures, a plurality of elastic outer clamps 17, and an elastic inner clamp 18;

[0060] A pair of chain conveyors 16 are installed inside the straightening box and are relatively inclined. The angle between the bottom ends of the pair of chain conveyors 16 is 15°. A plurality of elastic outer clamps 17 are evenly distributed on the chain of the chain conveyor 16. The elastic inner clamp 18 is arranged in the elastic outer clamp 17.

[0061] The elastic outer clamp 17 is claw-shaped, and the claw ends of the elastic outer clamp 17 can be crossed relative to each other. The elastic inner clamp 18 is arranged in the elastic outer clamp 17. The end face of the elastic inner clamp 18 has a column structure with a semicircular longitudinal section extending outward, and a plurality of anti-slip protrusions are provided on the column.

[0062] When the material (the material in this case refers to the metal wire) enters the straightening box and passes through the middle of the pair of chain conveyors 16, the chain conveyors 16 continuously convey the elastic outer clamping member 17. When the material passes through the middle of the pair of chain conveyors 16, the elastic inner clamping member 18 in the elastic outer clamping member 17 is fixed and carried downward. Since the pair of chain conveyors 16 have a relative inclined angle, the material is clamped more and more firmly when it is moved downward.

[0063] Specifically, the elastic outer clamp 17 is claw-type, and the two elastic outer clamps 17 can cross each other. The outer clamp pushes the inner clamp, and the inner clamp has a column structure. The material moves downward under the clamping of the column structure on the inner clamp symmetrically arranged on the left and right. This technical solution is to achieve smooth movement of the metal wire and to ensure that the metal wire moves evenly downward as much as possible, and the metal wire will not drop and stretch in large sections due to mechanical clamping, thereby preventing deformation of the metal wire.

[0064] Specifically, the material pouring structure includes: a pair of mounting blocks 19, a material pouring shaft 20, a material pouring motor 21, a material pouring tooth 22, and a motor fixing frame 23;

[0065] The pair of mounting blocks 19 are arranged inside the smelting furnace, FIG. 1, the material pouring shaft 20 is inserted on the pair of mounting blocks 19, the material pouring teeth 22 are sleeved on the material pouring shaft 20, the motor fixing frame 23 is arranged on the outer wall of the smelting furnace, FIG. 1, the material pouring motor 21 is arranged on the motor fixing frame 23, and the driving end of the material pouring motor 21 is connected to the material pouring shaft 20.

[0066] It should be noted that in order to ensure that the metal powder does not clog the bottom of the smelting furnace ( FIG. 1 ), the pouring motor 21 can be controlled to drive the pouring shaft 20. The pouring shaft 20 is inserted into a pair of mounting blocks 19, so that the pouring shaft 20 can rotate smoothly. The pouring shaft 20 rotates with the pouring teeth 22, and the pouring teeth 22 will overturn the metal powder.

[0067] Specifically, the gas emission purification equipment includes: a bag filter 24 and a dust collection box 255;

[0068] The bag filter 24 is connected to the smelting furnace 1 in the figure, and the dust collecting box 255 is connected to the bottom of the bag filter 24.

[0069] It should be noted that the present technical solution mainly utilizes the bag dust collector 24 for dust removal, and the large particles of dust enter the dust collection box 25 due to gravity.

[0070] Specifically, the feeding equipment includes: a feeding frame 26, a feeding motor 27, a pair of electric push rods 28, a pair of U-shaped shaft frames 29, a material shaft 30, a raw material roller 31, a raw material coil 32, a U-shaped connecting groove 33, and a U-shaped embedded block 34;

[0071] The feeding rack 26 is arranged on the supporting frame 2, the feeding motor 27 is located on the outer wall of the feeding rack 26, the U-shaped connecting groove 33 is connected to the driving end of the feeding motor 27, a pair of electric push rods 28 are arranged on the feeding rack 26, a pair of U-shaped shaft frames 29 are connected to the pair of electric push rods 28, the U-shaped connecting groove 33 is connected to the driving end of the feeding motor 27, a U-shaped embedded block 34 is connected to one end of the material shaft 30, the material shaft 30 is overlapped on the pair of U-shaped shaft frames 29, the U-shaped embedded block 34 can be inserted into the U-shaped connecting groove 33, the raw material roller 31 is sleeved on the material shaft 30, and the raw material coil 32 is sleeved on the raw material roller 31.

[0072] It should be noted that this technical solution has at least two forms;

[0073] The first form: normal feeding, the feeding motor 27 drives the U-shaped connecting groove 33 to rotate, and since the U-shaped embedded block 34 on the material shaft 30 is inserted into the U-shaped connecting groove 33, the material shaft 30 will rotate smoothly, and the rotation of the material shaft 30 will drive the raw material coil 32 on the raw material roller 31 to rotate, thereby realizing feeding;

[0074] The second form: to remove or replace the raw material coil 32, control a pair of electric push rods 28 to push the U-shaped shaft frame 29 to rise, and the material shaft 30 located on the U-shaped shaft frame 29 will rise, and the raw material roller 31 and the raw material coil 32 on the material shaft 30 will rise, and the U-shaped embedded block 34 on the material shaft 30 will be separated from the U-shaped connecting groove 33 on the feeding motor 27. Since the material shaft 30 is overlapped on the U-shaped shaft frame 29, the material shaft 30 can be removed and the raw material coil 32 can be replaced.

[0075] Specifically, the collection structure includes: a propulsion motor 35, a connecting column 36, a push-out plate 37, a storage box 38, a main connecting pipe 39 and a secondary connecting pipe 40;

[0076] The collecting box 5 is connected to the bottom of the smelting furnace 1 in FIG. 1 , and the propulsion motor 35 is arranged on the outer wall of the collecting box 5.

The outer wall of the collecting box 5 is provided with an automatic connection structure, which can connect the secondary connecting pipe 40 with the main connecting pipe 39.

[0077] It should be noted that when the metal powder enters the collection box 5, the propulsion motor 35 is controlled to push the connecting column 36, and the connecting column 36 pushes the ejection plate 37 to push the metal powder. After being squeezed, the metal powder will enter the secondary connecting pipe 40 through the main connecting pipe 39 and enter the storage chamber.

[0078] Specifically, the automatic connection structure includes: an annular fixing frame 41, a pair of first cylinders 42, and a pair of second cylinders 43;

[0079] The annular fixing frame 41 is fixed on the outer wall of the collecting box 5, the pair of first cylinders 42 are connected to the annular fixing frame 41, the pair of second cylinders 43 are connected to the piston ends of the pair of first cylinders 42, and the piston ends of the pair of second cylinders 43 are connected with arc-shaped fixing rings 46, which can clamp the outer wall of the secondary connecting pipe 40.

[0080] It should be noted that first, a pair of first cylinders 42 on the annular fixing frame 41 are controlled to push a pair of second cylinders 43 forward, and the second cylinders 43 push the annular fixing ring down, and the arc-shaped fixing ring 46 will clamp the secondary connecting pipe 40 to achieve fixation, and then the pair of first cylinders 42 pull the pair of second cylinders 43, and the secondary pipe is pulled to connect with the main connecting pipe 39.
