Description

[0002] Metal fibers refer to fibrous materials with a high metal content and continuous distribution of metal material, and transverse dimensions in the micrometer range. Metal fibers can be prepared using methods such as drawing, spinning, cutting, grinding, and metal plating sintering.

DETAILED DESCRIPTION

[0033] Please refer to Figures 1-9 , the technical scheme provided by the present application specifically includes the following embodiments:

[0034] A production device of superfine metal fibers, comprising an external frame 1 and a smelting machine 2, the smelting machine 2 is fixedly installed at the bottom end inside the external frame 1, a smelting furnace 3 is connected above the smelting machine 2, and the smelting furnace 3 is fixedly connected inside the external frame 1;

[0035] A high-frequency induction heater 4 is inlaidly installed on the front side of the smelting furnace 3, and the high-frequency induction heater 4 is used for heating metal raw materials;

[0036] Continuous smelting mechanism 5, the smelting furnace 3 inside sliding connection has continuous smelting mechanism 5, the continuous smelting mechanism 5 is cooperated with high-frequency induction heater 4 can continuously heat the metal with cooperation;

[0037] Feeding mechanism 6, the smelting furnace 3 one side fixed installation has feeding mechanism 6, and the feeding mechanism 6 extends to the upper of continuous smelting mechanism 5, and the feeding mechanism 6 is used for putting the metal raw material in continuous smelting mechanism 5;

[0038] Driving mechanism 7, the smelting furnace 3 bottom through connection has driving mechanism 7, and the driving mechanism 7 is used for controlling the up-down movement and rotation of continuous smelting mechanism 5.

[0039] The continuous smelting mechanism 5 includes shaft 51, the shaft 51 is slidably connected to the rear side wall inside the smelting furnace 3, the front side of the shaft 51 is fixedly connected with the cross 52, the four corners of the cross 52 are movably connected with the crucible 53 through the shaft, one of the crucible 53 is located in the high-frequency induction heater 4, the bottom side of the crucible 53 is fixedly connected with the arc-shaped rod 54.

[0040] The sliding connection between the shaft 51 and the smelting furnace 3 is achieved by using slide rails and slide sleeves. The slide rails are fixed to the rear side wall inside the smelting furnace, and the shaft 51 is movably connected to the slide sleeves, which are sleeved on the slide rails. Therefore, the continuous smelting mechanism 5 can move up and down and rotate at the same time. Since the crucible 53 is movably connected to the front side of the end of the cross 52 through the shaft, and the shaft connecting portion of the crucible 53 is close to the upper side, the crucible 53 will remain vertical regardless of the rotation of the cross 52 with the four crucibles 53. Only the crucible 53 on the right side with molten metal will be tilted when it is pushed down by the support 12 to pour the molten metal into the runner pipe 12. The arc-shaped rod 54 can be made of the same material as the crucible 53 or other non-metallic materials that can withstand high temperature, which can avoid the problem of being heated and melted when the crucible 53 enters the high-frequency induction heater 4.

[0041] The driving mechanism 7 is composed of a transmission arm 71, a servo motor 72, an electric push rod 73, and a connecting rod 74. The transmission arm 71 penetrates the bottom of the smelting furnace 3, and the top of the transmission arm 71 is sleeved on the outer end of the shaft 51. The electric push rod 73 is fixedly connected to the rear side of the outer frame 1. The connecting rod 74 is fixedly connected to the piston rod end of the electric push rod 73 and the rear side bottom of the transmission arm 71. The servo motor 72 is fixedly connected to the front side bottom of the transmission arm 71.

[0042] When driving the continuous smelting mechanism 5 to move up and down, the electric push rod 73 is mainly used as the drive to make the transmission arm 71 push the shaft 51 to move up and down, thereby making the continuous smelting mechanism 5 move up and down.

[0043] The transmission arm 71 comprises a first sleeve 711, a connecting pipe 712 and a second sleeve 713, the first sleeve 711 is sleeved on the outer end of the shaft rod 51, the second sleeve 713 is located below the smelting furnace 3, the connecting pipe 712 is fixedly connected between the first sleeve 711 and the second sleeve 713, the transmission rod 714 is movably connected in the connecting pipe 712, the first bevel gear 715 is fixedly connected to the outer end of the shaft rod 51 and the top of the transmission rod 714, the first bevel gear 715 is located in the first sleeve 711, the two first bevel gears 715 are meshed with each other, the second bevel gear 716 is fixedly connected to the output shaft of the servo motor 72 and the bottom of the transmission rod 714, the second bevel gear 716 is located in the second sleeve 713, and the two second bevel gears 716 are meshed with each other.

[0044] When it is needed to drive the continuous smelting mechanism 5 to rotate, the servo motor 72 is mainly used as the drive, and then the two second bevel gears 716, the transmission rod 714 and the two first bevel gears 715 in the transmission arm 71 are used as the transmission to drive the shaft rod 51 to rotate, so that the continuous smelting mechanism 5 rotates, when the shaft rod 51 rotates, the first sleeve 711 is movably connected with the shaft rod 51, and the joint between the two is sealed, including but not limited to mechanical sealing, which can ensure the airtightness of the smelting furnace 3 while not affecting the movable connection between the shaft rod 51 and the first sleeve 711, and helps to maintain the vacuum state in the smelting furnace 3, avoiding the generation of impurities in the metal melt.

[0045] The outer end of the connecting pipe 712 is sleeved with a sleeve 10, the sleeve 10 is fixedly connected to the inner bottom end of the smelting furnace 3, and the sleeve 10 and the connecting pipe 712 are also sealed, which can ensure the airtightness of the connection between the connecting pipe 712 and the smelting furnace 3 while not affecting the up-down movement of the connecting pipe 712, and at the same time, when the transmission arm 71 moves up and down to push the continuous smelting mechanism 5 to move up and down, the sleeve 10 can also guide and limit the transmission arm 71, so that it can only move up and down and cannot be inclined, thereby improving the stability of the driving mechanism 7 during operation.

[0046] The wide-gate runner pipe 11 is connected through the bottom of the smelting furnace 3, and the bottom of the wide-gate runner pipe 11 is fixedly connected with the feeding port of the smelting machine 2, one side of the wide-gate runner pipe 11 is fixedly connected with a push-down support 12, the push-down support 12 is located in the smelting furnace 3, and the push-down support 12 is used to push an adjacent one of the crucibles 53 so that the metal melt in the crucible 53 flows into the wide-gate runner pipe 11.

[0047] The wide mouth pouring pipe 11 is wide mouthed, which can better receive the metal melt poured from the crucible 53. The wide mouth pouring pipe 11 can pour the metal melt into the inside of the melt extractor 2 for the production and processing of superfine metal fibers. The specific structure of the push-down support 12 is composed of a bent rod, a vertical rod and two horizontal rods. The two horizontal rods are fixedly connected between the vertical rod and the wide mouth pouring pipe 11 in an up-down distribution. The bent rod is fixed at the top end of the vertical rod. When the right crucible 53 moves downward, the arc-shaped rod 54 at the bottom will first contact the push-down support 12. With the continuous downward movement of the crucible 53, the push-down support 12 will naturally push the crucible 53 along the arc-shaped rod 54 to tilt and exceed to the outside of the crucible 53, and will continue to push the crucible 53 along the outer wall of the crucible 53 to continue to tilt until the crucible 53 tilts to pour the metal melt inside it into the wide mouth pouring pipe 11. When the next metal raw material is heated and melted by the high-frequency induction heater 4, the continuous smelting mechanism 5 will move upward again. At this time, the tilted crucible 53 will automatically straighten.

[0048] The feeding mechanism 6 includes a rectangular box 61 fixedly connected to the top of one side of the smelting furnace 3. A feeding pipe 63 is fixedly connected to the bottom of one side of the rectangular box 61. The feeding pipe 63 penetrates through the smelting furnace 3 and extends into the inside of the smelting furnace 3. The end of the feeding pipe 63 is located directly above the uppermost crucible 53. A feeding hopper 62 is fixedly connected to the top of the rectangular box 61. A rectangular frame 64 is slidingly connected to the inside of the rectangular box 61. The rectangular frame 64 is located directly below the feeding hopper 62. A baffle 65 is fixedly connected to the top of one side of the rectangular frame 64. A multi-section electric push rod 66 is fixedly connected to the side of the rectangular box 61 away from the smelting furnace 3. The piston rod end of the multi-section electric push rod 66 is fixedly connected to the middle of one side of the rectangular frame 64.

[0049] When the metal raw material is put by the feeding mechanism 6, firstly, it is necessary to ensure that there is always metal raw material in the feeding hopper 62, and when the bottom of the feeding hopper 62 is not blocked, the metal raw material in the feeding hopper 62 will fall into the rectangular frame 64 in the rectangular box 61, and the metal raw material entering the rectangular frame 64 is roughly the same each time, which can achieve the effect of quantitative feeding each time. When feeding, the rectangular frame 64 is moved in the rectangular box 61 by the multiple electric push rods 66, and when the rectangular frame 64 is in communication with the feeding pipe 63, the metal raw material in the rectangular frame 64 will be put into the corresponding crucible 53 through the feeding pipe 63. During this period, although the rectangular frame 64 is no longer in communication with the feeding hopper 62, the side baffle 65 of the rectangular frame 64 can block the bottom of the feeding hopper 62, so that the metal raw material cannot enter the rectangular box 61 and cannot be quantitatively put by the rectangular frame 64. It is worth mentioning that the feeding pipe 63 is inclined, and the connection between the feeding pipe 63 and the rectangular box 61 is high, and the connection between the feeding pipe 63 and the straight crucible 53 is low. The connection between the feeding pipe 63 and the rectangular box 61 is funnel-shaped, wide at the top and narrow at the bottom, and the wide size is matched with the inner diameter of the rectangular frame 64. Therefore, the metal raw material in the rectangular frame 64 can enter the feeding pipe 63, and can be naturally put into the crucible 53 according to the direction of inclination and gravity. At the same time, during the feeding period, since the rectangular frame 64 is matched and sealed in the rectangular box 61, the smelting furnace 3 is not directly connected with the outside through the feeding mechanism 6, so as to ensure the vacuum effect in the smelting furnace 3.

[0050] The vacuum mechanism 8 is installed in the outer frame 1, and the vacuum mechanism 8 is used for vacuumizing the inside of the smelting furnace 3. The vacuum mechanism 8 comprises a vacuum pump 81 fixedly connected to the bottom end of the outer frame 1. The vacuum pump 81 is located on one side of the smelting furnace 2. An air pipe 82 is fixedly connected to the air inlet of the vacuum pump 81. The air pipe 82 is in communication with the inside of the smelting furnace 3. An electromagnetic valve 83 is installed on the air pipe 82.

[0051] When the gas pressure sensor 14 detects that the gas pressure in the smelting furnace 3 is not up to standard, the controller 9 drives the vacuum pump 81 to operate until the smelting furnace 3 is vacuumized. After vacuumizing, the electromagnetic valve 83 is opened to break the circuit of the air pipe 82. At this time, the vacuum pump 81 can be closed, and the smelting furnace 3 can maintain a vacuum state.

[0052] The controller 9 is fixedly installed at the upper right corner of the front side of the outer frame 1. The smelting furnace 2, the high-frequency induction heater 4, the feeding mechanism 6, the driving mechanism 7 and the vacuum mechanism 8 are electrically connected with the controller 9. The controller 9 is mainly used for the control of electrical appliances. Since such control devices are relatively common, the rectangular type of the controller 9 is not limited, and the specific connection mode (such as wire connection) is not described in detail.

[0053] The temperature sensor 13 and the air pressure sensor 14 are fixedly connected to one side inside the smelting furnace 3, the temperature sensor 13 is located above the air pressure sensor 14, and the temperature sensor 13 and the air pressure sensor 14 are electrically connected with the controller 9; the temperature sensor 13 can detect the real-time temperature in the smelting furnace 3, the air pressure sensor 14 can detect the real-time air pressure in the smelting furnace 3, and the air pressure sensor 14 is also used in cooperation with the vacuum mechanism 8.

[0054] The production of superfine metal fibers requires different equipment according to different production processes. The technical solution of the present application is a spinning method, i.e. a melt extraction method. This process requires heating and melting of metal raw materials, such as smelting furnace 3 and its internal and external related structures. Then the molten metal liquid is sprayed into a wire, such as melt extraction machine 2. The melt extraction machine 2 is a melt extraction device. Since this type of melt extraction device is a product of prior art, the melt extraction machine 2 is directly mentioned here, and the specific working principle and internal structure are not described in detail.

[0055] In addition, based on the above embodiments and without considering the increase in cost, the number of high-frequency induction heaters 4 can be appropriately increased, and the positions of the wide-gate runner pipe 11 and the push-down support 12 need to be adjusted. For example, while retaining the corresponding high-frequency induction heater 4 above the upper crucible 53, a corresponding high-frequency induction heater 4 can also be installed on the right side and below the crucible 53. Then, the wide-gate runner pipe 11 and the push-down support 12 are installed at appropriate positions on the left side of the crucible 53. In this way, the metal raw materials can be heated in multiple stages to avoid the situation that a single high-frequency induction heater 4 cannot quickly melt the metal to match the speed of pouring the metal melt. This scheme only changes the number of high-frequency induction heaters 4 and appropriately adjusts the positions of the components. Therefore, no corresponding pictures are provided here, but the feasibility of this scheme cannot be denied, and it is also within the scope of the technical solution of the present application.

[0056] Working principle:

[0057] Before using the melt extraction machine 2 to melt the metal fibers, the metal raw materials need to be heated to melt them;

[0058] When the metal raw materials are heated, the metal raw materials are introduced into the inside of the feeding hopper 62, and then the metal raw materials fall into the inside of the rectangular frame 64 in the rectangular box 61. The rectangular frame 64 is pushed to the left by the multiple electric push rods 66 until it is connected with the feeding pipe 63. At this time, the bottom of the feeding hopper 62 is blocked by the baffle 65, so that the metal raw materials cannot enter the inside of the rectangular box 61. The quantitative metal raw materials in the rectangular frame 64 are introduced into the inside of the uppermost crucible 53 in the continuous smelting mechanism 5 through the feeding pipe 63;

[0059] When the continuous smelting mechanism 5 is driven to move downward by the driving mechanism 7 so that the uppermost one of the crucibles 53 is located inside the high-frequency induction heater 4, the high-frequency induction heater 4 can heat the metal raw material in the crucible 53 to melt it, and then the continuous smelting mechanism 5 is driven to move upward and rotate by the driving mechanism 7, when the continuous smelting mechanism 5 moves upward, the crucible 53 in the high-frequency induction heater 4 moves upward synchronously and is taken out, and then the continuous smelting mechanism 5 rotates so that the uppermost crucible 53 rotates to the right side and the crucible 53 on the left side rotates to the upper side, at this time, the feeding mechanism 6 can feed the metal raw material into the corresponding empty crucible 53, and then the driving mechanism 7 drives the continuous smelting mechanism 5 to move downward, during which the upper crucible 53 gradually enters the high-frequency induction heater 4 to be heated and melted, and the arc-shaped rod 54 at the bottom of the crucible 53 on the right side will contact the push-down support 12 and gradually push the crucible 53 down with the downward movement of the arc-shaped rod 54 and the push-down support 12, until the metal melt in the crucible 53 is poured into the wide-mouth pouring pipe 11, and then the metal melt is guided into the melt extractor 2 through the wide-mouth pouring pipe 11 to extract metal fibers, and then the above steps are repeated when the metal raw material in the upper crucible 53 is heated and melted by the high-frequency induction heater 4 again.

[0060] During the process, the temperature and air pressure in the smelting furnace 3 are monitored by the temperature sensor 13 and the air pressure sensor 14, when the air pressure is not up to standard, the air in the smelting furnace 3 can be extracted by the vacuum mechanism 8 to make the inside of the smelting furnace 3 in a vacuum state.

[0061] When the continuous smelting mechanism 5 is driven to move up and down by the driving mechanism 7, the transmission arm 71 can be pushed up and down by the electric push rod 73 and the connecting rod 74, and when the transmission arm 71 moves up and down, the shaft 51 moves up and down, and then the continuous smelting mechanism 5 moves up and down, when the continuous smelting mechanism 5 is driven to rotate by the driving mechanism 7, the servo motor 72 is used as the driving source, and the second bevel gear 716, the transmission rod 714 and the first bevel gear 715 are used as the transmission to drive the shaft 51 to rotate, and then the continuous smelting mechanism 5 rotates.
