Description

Technical Field

[0001] The utility model belongs to the technical field of micro-nano powder preparation, and in particular relates to a continuous wire pressing mechanism and wire electric explosion powder making equipment. Background Art

[0002] Micro-nano powder refers to powder formed by ultrafine particles with a particle size not exceeding 30μm. Studies have found that micro-nano powder materials show some new excellent properties in terms of sound, light, electromagnetism, thermodynamics, corrosion resistance, catalysis, and mechanical properties. It will produce surface effects, volume effects, small size effects, and macroscopic quantum tunneling effects. With the continuous research on the action of high-density current on metal wires, it was found that metal wires can form ultrafine powders under the action of high-density currents. This method is called metal wire electric explosion method. This method has the advantages of pulse technology, high energy utilization, no waste, and green friendliness. The prepared micro-nano powders have the advantages of high purity, good dispersibility, and good sphericity.

[0003] Wire electric explosion refers to the process in which a metal wire, under the action of a pulsed large current with certain parameters, undergoes solid heating, melting, liquid heating, and gasification in a very short time, causing an electric explosion and forming plasma, accompanied by the generation of shock waves and light. Finally, under the action of the explosion impact force, it splashes around at high speed and finally cools into micro-nano powder. This method has the advantages of strong versatility, good powder sphericity, controllable particle size, and green and pollution-free.

[0004] The metal wire electric explosion method has great advantages in preparing micro-nano powders. In recent years, this technology has received widespread attention. At present, there are equipment that can prepare micro-nano powders. However, when mass-producing micro-nano powders in an automated manner, there are two main problems. First, most of the existing electric explosion equipment uses solid contact between electrodes and metal wires, and then a pulse current is applied between the two electrodes to the metal wire to prepare micro-nano powders. In practice, it is found that this preparation method will cause electrode ablation problems, affecting the subsequent preparation process.

[0005] To solve this problem, Chinese patent CN102151838B discloses a wire electric explosion device that uses gas discharge to introduce current. The metal wire does not contact the electrode. A large current passes through the air gap between the electrode and the metal wire to break down the air gap and achieve conduction, thereby reducing the ablation of the electrode. However, this solution is still lacking in continuous wire electric explosion. Since the metal wire is pressed at the same position for wire electric explosion, the ablation problem of the pressure rod and the wire guide rod will occur, resulting in a small number of continuous electric explosions. Second, the existing equipment often cannot press wire continuously. Chinese patent CN114932229B discloses a solution that uses gear rotation to drive the operation of the wire pressing mechanism. However, it is found in practice that in the process of continuous wire pressing, the two gears of this solution are prone to non-meshing, and continuous and stable wire feeding is often not possible.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0007] In view of the problems in the related technology, the utility model proposes a continuous wire pressing mechanism and wire electric explosion powder making equipment to overcome the above technical problems existing in the existing related technology.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a continuous wire pressing mechanism, comprising a wire feeding tool and a wire reel, wherein the wire reel is rotatably mounted on the outer surface of an electric explosion chamber, the wire feeding tool is arranged on the inner wall of the electric explosion chamber, the wire reel is used to wind a metal wire, the wire feeding tool comprises a disc and a driving unit for driving the disc to rotate, at least three groups of wire guiding mechanisms are arranged on the disc; the wire guiding mechanisms are all provided with a wire pressing unit; and an inclined plate is also included, wherein the inclined plate is connected to the electric explosion chamber through a supporting rod, and the inclined plate is used to abut against the wire pressing unit to make the wire pressing unit slide;

[0010] The driving unit drives the disc to rotate, so as to drive the wire guiding mechanism on the disc to rotate synchronously, so that the wire pressing unit contacts the inclined plate, and as the disc continues to rotate, the wire pressing unit and the wire guiding mechanism slide relative to each other until the metal wire contacts the wire guiding mechanism, and then the wire pressing unit detaches from the inclined plate to reset, so that it cooperates with the wire guiding mechanism to complete the three-point clamping of the metal wire.

[0011] Furthermore, the driving unit includes a large motor, a main shaft, a small motor, a reciprocating screw and a threaded motherboard, an elastic coupling and a dynamic sealing bearing, wherein the main shaft is connected to the electric explosion chamber through a dynamic sealing bearing, one end of the main shaft is fixedly mounted on the disc, and the other end is connected to the large motor through an elastic coupling, the large motor is fixedly mounted on the threaded motherboard, the threaded motherboard is threadedly connected to the reciprocating screw, and the reciprocating screw is fixedly mounted on the output shaft of the small motor, and the small motor is fixedly mounted on the outer wall of the electric explosion chamber.

[0012] Furthermore, the inclined plate is slidably mounted on the support rod, and the support rod is fixedly mounted on the inner wall of the electric explosion chamber, and the inclined plate penetrates and is rotatably mounted on the main shaft.

[0013] Furthermore, the wire guide mechanism comprises a sleeve disposed on the disc, one end of two wire guide rods being fixedly mounted on the sleeve, and the other ends of the two wire guide rods being fixedly mounted on the side of the ring;

[0014] It also includes a wire guide wheel, which is arranged on the inner wall of the electric explosion chamber and is located between the wire feeding tool and the wire reel.

[0015] Furthermore, the wire pressing unit includes a sliding rod slidably connected to the sleeve, a pulley is rotatably installed on one end of the sliding rod, and the pulley is used to interfere with the inclined surface of the inclined plate. A pressure rod is fixedly installed on the end of the sliding rod away from the pulley, and a return spring is sleeved on the sliding rod. The two ends of the return spring are respectively installed on the pressure rod and the sleeve.

[0016] A wire electric explosion powder making device, comprising an electrode mechanism, wherein the electrode mechanism comprises a grounding electrode and a high-voltage electrode, and the distance between the grounding electrode and the high-voltage electrode is equal to the distance between any two adjacent pressure rods;

[0017] When the disc rotates to the set position, two adjacent pressure rods are simultaneously brought close to the ground electrode and the high-voltage electrode respectively.

[0018] Furthermore, one end of the ground electrode and the high-voltage electrode extend to the outside of the electric explosion chamber and are sealed and connected by the rubber ring.

[0019] The utility model has the following beneficial effects:

[0020] The utility model drives the disc to rotate through a driving unit, and the disc drives the wire guide rod to rotate synchronously through a sleeve. When the metal wire is drawn out from the wire disc and overlapped on the adjacent wire guide rod through the wire guide wheel, the pulley corresponding to the wire guide rod contacts the inclined surface of the inclined plate.

As the disc rotates, each wire guide mechanism and the wire pressing unit repeat the above operation, so that the metal wire can be fixed on each wire guide rod in sections. When in use, the metal wire between adjacent wire guide mechanisms is continuously electro-exploded. Since the metal wire is segmented and fixed by three-point wire pressing, the subsequent metal wire will not be separated from the wire guide rod after electro-explosion, thereby realizing stable and continuous wire feeding.

[0021] In order to further improve the smoothness of wire feeding, the utility model is provided with a wire guide wheel between the wire reel and the wire feeding tooling. After the metal wire is guided by the wire guide wheel, the axis of the wire guide wheel and the discharge positions of the ground electrode and the high-voltage electrode remain in the same plane, and the wire can enter the wire feeding tooling at a more gentle input angle, thereby improving the wire feeding stability.

[0022] The utility model drives the reciprocating screw rod to move by a small motor, so that the main shaft drives the disc to move, thereby changing the position of the metal wire overlapped on the wire rod, so that the electric explosion position is also changed, which can avoid the metal wire being exploded at the same position for a long time, resulting in ablation of the wire rod and the pressure rod.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 3 As shown, the utility model is a continuous wire pressing mechanism, including a wire feeding tool and a wire reel 2, the wire reel 2 is rotatably mounted on the outer surface of the electric explosion chamber 1, the wire feeding tool is arranged on the inner wall of the electric explosion chamber 1, the wire reel 2 is used to wind the metal wire 20, the wire feeding tool includes a disc 3 and a driving unit for driving the disc 3 to rotate, and at least three groups of wire guiding mechanisms are arranged on the disc 3; the wire guiding mechanisms are all provided with wire pressing units; and also include an inclined plate 17, the inclined plate 17 is connected to the electric explosion chamber 1 through a support rod 18, and the inclined plate 17 is used to resist the wire pressing unit to make the wire pressing unit slide;

[0033] By setting different numbers of wire guiding mechanisms, the length of the metal wire consumed during each electric explosion can be adjusted. The effect of electric explosion of metal wires of different diameters can also be achieved by adjusting the distance between the wire guiding mechanism (specifically the guide rod hereinafter) and the wire pressing unit (specifically the pressure rod hereinafter).

[0034] The driving unit drives the disc 3 to rotate, so as to drive the wire guiding mechanism on the disc 3 to rotate synchronously, so that the wire pressing unit contacts the inclined plate 17, and as the disc 3 continues to rotate, the wire pressing unit and the wire guiding mechanism slide relative to each other until the metal wire contacts the wire guiding mechanism, and then the wire pressing unit disengages from the inclined plate 17 to reset, so that it cooperates with the wire guiding mechanism to complete the three-point clamping of the metal wire.

[0035] When in use, the metal wire 20 with a diameter of 0.2-1 mm to prepare the micro-nano powder is decontaminated and wound on the wire disc 2, and then the electric explosion chamber 1 is closed to make it sealed. The vacuum pump is turned on, and the air pressure in the electric explosion chamber 1 is reduced to below 200 Pa through the air outlet valve on the electric explosion chamber 1, the air outlet valve is closed, the air inlet valve is opened, and argon gas is introduced to raise the air pressure in the electric explosion chamber 1 to 0.8 standard atmospheric pressure, and the air inlet valve is closed.

[0036] In one embodiment, for the above-mentioned inclined plate 17, the inclined plate 17 and the support rod 18 are slidably installed, and the support rod 18 is fixedly installed on the inner wall of the electric explosion chamber 1, and the inclined plate 17 passes through and is rotatably installed on the main shaft 11; wherein the rotational installation between the inclined plate 17 and the main shaft 11 is realized by a bearing, so that the inclined plate 17 and the main shaft 11 only rotate relative to each other in the original position without generating relative sliding.

[0037] The wire guide mechanism comprises a sleeve 4 provided on the disc 3, one end of two wire guide rods 5 are fixedly mounted on the sleeve 4, and the other ends of the two wire guide rods 5 are fixedly mounted on the side of the ring 19;

[0038] It also includes a wire guide wheel 24, which is arranged on the inner wall of the electric explosion chamber 1 and is located between the wire feeding tool and the wire reel 2; in order to further improve the stability of the transportation of the metal wire 20, the axis of the pressure rod 8, the axis of the disc 3 and the axis of the wire reel 2 are kept parallel, so that the position of the metal wire on the several wire guide rods will not be displaced, even if the metal wire forms an approximate circle, so that the metal wire 20 will not deviate during the transportation process.

[0039] The wire pressing unit includes a sliding rod 6 slidably connected to the sleeve 4, a pulley 7 is rotatably installed on one end of the sliding rod 6, and the pulley 7 is used to contact the inclined surface of the inclined plate 17. A pressure rod 8 is fixedly installed on the end of the sliding rod 6 away from the pulley 7. A return spring 9 is sleeved on the sliding rod 6, and both ends of the return spring 9 are respectively installed on the pressure rod 8 and the sleeve 4.

[0040] The end of the pressure rod 8 away from the pulley 7 is tapered. When the pressure rod 8 performs a reset movement, the inclined surface of the tapered end is used to squeeze the metal wire 20 to be concave between the two wire guide rods 5, and the wire guide rods 5 and the pressure rod 8 form a three-point clamp for the metal wire.

[0041] The disc 3 is driven to rotate by the driving unit, and the disc 3 drives the wire guide rod 5 to rotate synchronously through the sleeve 4. When the metal wire 20 is drawn out from the wire disc 2 and before being overlapped on the adjacent wire guide rod 5 through the wire guide wheel 24, the pulley 7 corresponding to the wire guide rod 5 contacts the inclined surface of the inclined plate 17. As the disc 3 rotates, the pulley 7 moves along the inclined plate 17 and drives the slide rod 6 to move backward, so that the pressure rod 8 moves backward. At this time, the return spring 9 is compressed, and then the metal wire 20 can be overlapped on the wire guide rod 5; thereafter, the pulley 7 continues to move and leaves the inclined plate 17 as the disc 3 rotates, and the return spring 9 is no longer restricted. , so that the pressure rod 8 returns to its original position under the action of the return spring 9 in the compressed state, so that the pressure rod 8 and the two wire guide rods 5 press the metal wire 20 at the same time, and then the metal wire is pressed between the two wire guide rods 5 by the pressure rod 8. As the disc 3 rotates, each wire guiding mechanism and the wire pressing unit repeat the above operation, so that the metal wire 20 can be fixed on each wire guide rod 5 in sections. When in use, the metal wire 20 between adjacent wire guiding mechanisms is continuously electro-exploded. Since the metal wire is segmented and fixed by three-point wire pressing, the subsequent metal wire 20 will not be detached from the wire guide rod 5 after electro-explosion, thereby realizing stable and continuous wire feeding.

[0042] In one embodiment, for the above-mentioned drive unit, the drive unit includes a large motor 10, a main shaft 11, a small motor 12, a reciprocating screw 13 and a wire motherboard 14, an elastic coupling 15 and a dynamic sealing bearing 16, wherein the main shaft 11 is connected to the electric explosion chamber 1 through the dynamic sealing bearing 16, one end of the main shaft 11 is fixedly mounted on the disc 3, and the other end is connected to the large motor 10 through the elastic coupling 15, the large motor 10 is fixedly mounted on the wire motherboard 14, the wire motherboard 14 is threadedly connected to the reciprocating screw 13, and the reciprocating screw 13 is fixedly mounted on the output shaft of the small motor 12, and the small motor 12 is fixedly mounted on the outer wall of the electric explosion chamber 1.

[0043] When in use, the large motor 10 and the small motor 12 are started, the small motor 12 drives the reciprocating screw 13 to rotate, the reciprocating screw 13 drives the screw master plate 14 to move axially, and the screw master plate 14 drives the main shaft 11 to move axially; the large motor 10 drives the main shaft 11 to rotate, and the main shaft 11 drives the disc 3 to move circumferentially and axially, thereby achieving the purpose of driving the disc 3 to move.

[0044] The reciprocating screw rod 13 is driven to rotate by a small motor 12, so that the main shaft 11 drives the disk 3 to move along the central axis direction of the main shaft 11, thereby changing the position of the metal wire 20 overlapped on the guide wire rod 5, so that the electric explosion position is also changed, which can prevent the metal wire 20 from being electrically exploded at the same position for a long time, causing ablation of the guide wire rod 5 and the pressure rod 8.

[0045] In addition, the structure of the pressure rod 8 and the guide wire rod 5 is that the middle metal rod is wrapped with a layer of insulating plastic on the outer layer, and the ring 19 is made of insulating plastic, but is not limited to this. It can also be made of other solid insulating materials with equivalent effects such as rubber and ceramics, which are not specifically limited here.

[0046] A wire electric explosion powder making device, comprising an electrode mechanism, wherein the electrode mechanism comprises a grounding electrode 21 and a high-voltage electrode 22, wherein the distance between the grounding electrode 21 and the high-voltage electrode 22 is equal to the distance between any two adjacent pressure rods 8;

[0047] When the disk 3 rotates to the set position, the two adjacent pressure rods 8 are simultaneously brought close to the ground electrode 21 and the high-voltage electrode 22 respectively.

[0048] Furthermore, one end of the ground electrode 21 and the high voltage electrode 22 extend to the outside of the electric explosion chamber 1 and are sealed and connected by the rubber ring 23 .

[0049] In order to further improve the smoothness of wire feeding, a wire guide wheel 24 is provided between the wire reel 2 and the wire feeding tooling. After the metal wire 20 is guided by the wire guide wheel 24, the axis of the wire guide wheel 24 maintains the same plane as the discharge positions of the ground electrode 21 and the high-voltage electrode 22, and can enter the wire feeding tooling at a smoother input angle, thereby improving the wire feeding stability.

[0050] When the metal wire 20 is sent between the two electrodes, 8-15kV voltage is applied to the high-voltage electrode 22, and electric explosion is achieved by air gap breakdown between the high-voltage electrode 22 and the grounding electrode 21 and the metal wire 20. Therefore, the metal wire 20 undergoes heating, melting, liquefaction, gasification, explosion diffusion, etc. in a very short time, forming plasma and settling into micro-nano powder.

[0051] The ground electrode 21 and the high voltage electrode 22 are sealed with a rubber ring 23 when penetrating the electric explosion chamber 1 , thereby ensuring the sealing performance of the electric explosion chamber 1 .

[0052] Through the above technical solution, the disc 3 is driven to rotate by the driving unit, and the disc 3 drives the wire guide rod 5 to rotate synchronously through the sleeve 4. When the metal wire 20 is drawn out from the wire disc 2 and before it is overlapped on the adjacent wire guide rod 5 through the wire guide wheel 24, the pulley 7 corresponding to the wire guide rod 5 contacts the inclined surface of the inclined plate 17. As the disc 3 rotates, the pulley 7 moves along the inclined plate 17 and drives the slide rod 6 to move backward, so that the pressure rod 8 moves backward. At this time, the return spring 9 is compressed, and then the metal wire 20 can be overlapped on the wire guide rod 5; thereafter, the pulley 7 continues to move and leaves the inclined plate as the disc 3 rotates, and the return spring 9 is no longer The metal wire 20 is restricted, so that the pressure rod 8 returns to its original position under the action of the return spring 9 in the compressed state, so that the pressure rod 8 and the two wire guide rods 5 press the metal wire 20 at the same time, and then the metal wire is pressed between the two wire guide rods 5 by the pressure rod 8. As the disc 3 rotates, each wire guide mechanism and the wire pressing unit repeat the above operation, so that the metal wire 20 can be fixed on each wire guide rod 5 in sections. When in use, the metal wire 20 between adjacent wire guide mechanisms is continuously electro-exploded. Since the metal wire is segmented and fixed by three-point wire pressing, the subsequent metal wire 20 will not be separated from the wire guide rod 5 after electro-explosion, thereby realizing stable and continuous wire feeding.

[0053] In order to further improve the smoothness of wire feeding, a wire guide wheel 24 is provided between the wire reel 2 and the wire feeding tooling. After the metal wire 20 is guided by the wire guide wheel 24, the axis of the wire guide wheel 24 and the discharge positions of the ground electrode 21 and the high-voltage electrode 22 are kept in the same plane, and the metal wire 20 can enter the wire feeding tooling at a more gentle input angle, thereby improving the wire feeding stability.

[0054] The reciprocating screw rod 13 is driven to move by the small motor 12, so that the main shaft 11 drives the disc 3 to move, thereby changing the position of the metal wire 20 overlapped on the guide wire rod 5, so that the electric explosion position is also changed, which can avoid the metal wire 20 being electrically exploded at the same position for a long time, causing ablation of the guide wire rod 5 and the pressure rod 8.
