Description
Technical Field
[0001] This invention relates to the field of metal wire processing technology, and more specifically, to a micro-metal wire drawing machine. Background Technology
[0002] During the micro-wire drawing process, the high-speed friction between the metal wire and the drawing die and roller generates a large amount of metal debris and high temperature. It is necessary to continuously spray coolant to achieve lubrication, cooling and chip removal.
[0003] The coolant circulation systems of existing wire drawing machines generally have the following defects:
[0004] First, traditional filters are static filters, and metal debris easily accumulates and clogs the pores, leading to poor coolant flow, cooling and lubrication failure, and affecting the surface quality of the wire and the life of the mold. Second, cleaning the filter requires stopping the machine for disassembly, interrupting the production process and reducing processing continuity and efficiency. Finally, when the roller rotates at high speed, internal heat accumulates, and the coolant cannot circulate actively, causing the roller to expand due to heat, reducing the precision of the wire, and even causing wire breakage and scratches. Summary of the Invention

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0034] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.
[0035] Example 1, please refer to Figure 1-12 The present invention provides the following technical solutions:
[0036] A micro-metal wire drawing machine specifically includes a machine body 1 and several water tanks 2 fixed on the machine body 1; symmetrically rotatably arranged rollers 3 are arranged inside the water tanks 2; filter boxes 4 are fixed on the side of the water tanks 2; and a transmission part 5 is rotatably arranged through the inner wall of the filter box 4 and is coaxially frictionally connected to the corresponding rollers 3.
[0037] The transmission unit 5 includes a liquid extraction pipe 6; a filter element 7 is symmetrically and slidably arranged on the liquid extraction pipe 6; the filter element 7 includes an annular filter cover 8 that rotates with the bottom surface of the filter box 4 and a conical cover 9 that slides with the outer wall of the liquid extraction pipe 6.
[0038] A curved rubber cover 10 is fixed to the inner wall of the annular filter cover 8; an annular plate 11 that rotates with the conical cover 9 is fixed to the end of the curved rubber cover 10; several sliding rods 12 that slide through and slide with the annular filter cover 8 are fixed to the side of the annular plate 11; and a drive unit for controlling the movement of the two conical covers 9 is installed on the filter box 4.
[0039] The slide bar 12 is used to limit the relative position of the annular plate 11 and the annular filter cover 8, ensuring the stability of the curved rubber cover 10 during expansion and contraction; the conical cover 9 is slidably engaged with the liquid extraction pipe 6, and can move axially and rotate synchronously with the liquid extraction pipe 6; the annular filter cover 8 is rotatably engaged with the bottom surface of the filter box 4, ensuring smooth rotation, and at the same time limiting the axial direction of the annular filter cover 8.
[0040] In use, the control drive unit moves the two conical covers 9 away from each other until they press against the corresponding annular filter cover 8. The annular filter cover 8 rotates synchronously with the conical covers 9 and the liquid extraction pipe 6 to achieve centrifugal filtration of metal impurities in the coolant. By controlling the two conical covers 9 to move closer to each other until they are pressed together, the limit on the annular filter cover 8 is released, and the metal impurities inside the two annular filter covers 8 can be cleaned online.
[0041] Working principle of this embodiment:
[0042] Centrifugal filtration state: The drive unit drives the two conical covers 9 to move away from each other along the liquid extraction pipe 6 until the conical covers 9 press against the annular filter cover 8, and the conical covers 9 and the annular filter cover 8 form a synchronous rotation structure; the liquid extraction pipe 6 rotates coaxially with the tower wheel 3, and the coolant enters the interior of the annular filter cover 8 through the liquid extraction pipe 6. The centrifugal force generated by the high-speed rotation throws the metal impurities toward the inner wall of the annular filter cover 8, and the clean coolant flows back to the filter box 4 through the filter cover, realizing dynamic centrifugal filtration.
[0043] Online cleaning status: The drive unit moves the two conical covers 9 closer together and presses them together. The conical covers 9 release the rotation limit on the annular filter cover 8. The curved rubber cover 10 contracts with the conical covers 9, and the annular filter cover 8 can stop rotating. At this time, the metal impurities accumulated inside the annular filter cover 8 can be cleaned online directly in the filter box 4 without stopping the machine for disassembly.
[0044] Example 2, please refer to Figure 1-12 This second embodiment is an improvement on the first embodiment as follows: Specifically, the suction tube 6 includes two coaxially arranged connecting tubes 13. A limiting rail is fixed to the outer wall of the connecting tube 13. A limiting groove is opened on the inner wall of the conical cover 9 to slide in accordance with the limiting rail, so that the conical cover 9 can only slide along the axial direction of the connecting tube 13 and rotate synchronously with the connecting tube 13. Several extension rods 14 are fixed between the two connecting tubes 13. A lug tube 15 is fixed to the end of a set of connecting tubes 13. A threaded ring 16 is screwed onto the lug tube 15. A rotating ring 17 is rotatably arranged on the outer wall of the threaded ring 16. A first friction wheel 18 is fixed to the outer wall of the rotating ring 17. A second friction wheel 19 adapted to the first friction wheel 18 is fixed to one end of the tower wheel 3. Fastening nuts are symmetrically screwed onto the lug tube 15 on both sides of the first friction wheel 18.
[0045] Rotate the threaded ring 16 to move it along the ear tube 15 toward the direction of the tower wheel 3, so that the first friction wheel 18 presses against the second friction wheel 19 at the end of the tower wheel 3. Tighten the fastening nuts on both sides of the first friction wheel 18 to ensure the stability of the friction transmission connection between the first friction wheel 18 and the second friction wheel 19, realize the rigid linkage between the transmission part 5 and the tower wheel 3, and ensure that the liquid extraction tube 6 rotates synchronously with the tower wheel 3.
[0046] A wire drawing die 20 is installed inside the water tank 2; a rotating shaft 21 is fixed at the other end of the tower wheel 3 and rotates through the side of the water tank 2; a first sprocket 22 is fixed at the end of the rotating shaft 21; a second sprocket 23 is symmetrically arranged on the side of the water tank 2 between the two first sprockets 22; a chain 24 is provided for meshing and transmission between each first sprocket 22 and the second sprocket 23; a set of drive motors are installed on the side of the water tank 2; the output end of the drive motor is fixedly connected to the corresponding first sprocket 22.
[0047] By setting the second sprocket 23, the stability of the chain 24 transmission between each group of first sprockets 22 is improved. The drive motor drives the first sprocket 22 to rotate, and through the chain 24 and the second sprocket 23, drives all the tower wheels 3 to rotate synchronously, and drives the metal wire through the drawing die 20 to complete continuous drawing.
[0048] The drive unit includes a bidirectional lead screw 25 that is rotatably mounted on the side of the filter box 4 and guide rods 26 that are symmetrically fixed on the side of the filter box 4; a fastening nut is screwed onto the bidirectional lead screw 25; a fixing plate 27 that is symmetrically slidably mounted between the two guide rods 26 and screwed onto the bidirectional lead screw 25; a fixing sleeve 28 is fixed to the bottom surface of the fixing plate 27; a support ring 29 is rotatably mounted on the side of the conical cover 9; an L-shaped plate 30 is fixed to the side of the support ring 29; the L-shaped plate 30 and the fixing sleeve 28 are fixedly connected by fastening bolts.
[0049] A connecting cover 31 is fixed to the end of the annular filter cover 8; the two connecting cover 31 are connected by a zipper; a number of support bases 32 that rotate and cooperate with the corresponding annular filter cover 8 are evenly fixed on the bottom surface of the filter box 4; a third friction wheel 33 is fixed on the outer wall of the conical cover 9; a fourth friction wheel 34 that is adapted to the third friction wheel 33 is fixed on the inner wall of the annular filter cover 8; a liquid pump is installed inside the filter box 4; a nozzle 49 is installed on the top of the water tank 2; the output end of the liquid pump is connected to the nozzle 49 through a hose.
[0050] The two connecting covers 31 are connected by a zipper. By unzipping the zipper, the two annular filter covers 8 can be opened, which facilitates online cleaning of metal impurities inside the two annular filter covers 8.
[0051] Working principle of this embodiment two:
[0052] Centrifugal filtration: Rotating the bidirectional lead screw 25 drives the two fixed plates 27 and the corresponding two filter elements 7 to slide away synchronously, thereby causing the two conical covers 9 to slide away, and thus making the annular filter cover 8 connected to the inside of the liquid extraction pipe 6. During this process, the third friction wheel 33 on the conical cover 9 moves towards the corresponding fourth friction wheel 34 until the third friction wheel 33 presses against the fourth friction wheel 34. Tighten the corresponding fastening nut to prevent the bidirectional lead screw 25 from rotating. The two sets of annular filter covers 8 rotate synchronously with the conical covers 9 and the liquid extraction pipe 6. Control the start of the liquid extraction pump to deliver the coolant in the filter box 4 to the nozzle 49 through the hose. The coolant is sprayed through the nozzle 49 onto the metal wire in the water tank 2 to cool and lubricate the metal wire during the wire drawing process. The coolant in the water tank 2 flows into the inside of the annular filter cover 8 through the liquid extraction pipe 6. The rotating annular filter cover 8 centrifugally filters the metal impurities in the coolant, realizing the circulation filtration of the coolant.
[0053] Online cleaning: Turn off the corresponding liquid pump, loosen the corresponding fastening bolts, and rotate the bidirectional lead screw 25 in the opposite direction to drive the two fixed plates 27 and the corresponding two filter elements 7 to slide closer together, so that the two conical covers 9 slide closer together until they abut against each other. The corresponding two curved rubber covers 10 separate the inside of the two annular filter covers 8 from the conical covers 9. The third friction wheel 33 and the fourth friction wheel 34 disengage. Unzip the zipper to directly clean the impurities inside the annular filter cover 8. After cleaning, unzip the zipper and reset the conical covers 9 to restore filtration.
[0054] Example 3, please refer to Figure 1-12 This embodiment three is an improvement on the first embodiment as follows: Specifically, an ear rod 35 is fixed to the inner wall of the tower wheel 3; a ball head 36 is fixed to the end of the ear rod 35; a coaxial shaft hole 37 is opened at the end of the connecting pipe 13 and the ear tube 15; a sliding part 38 is slidably provided inside the connecting pipe 13 and the ear tube 15.
[0055] The sliding part 38 includes a connecting rod 39 that slides with the shaft hole 37; one end of the connecting rod 39 is fixed with a conical block 40 that is adapted to the inner wall of the tower wheel 3, and the other end is fixed with a piston plate 41; one end of the conical block 40 is fixed with a slip ring 42 that slides with the end of the tower wheel 3; a plurality of filter holes 43 are evenly opened on the side of the slip ring 42; the other end of the conical block 40 is fixed with a curved guide plate 44 that is adapted to the ball head 36.
[0056] The sliding part 38 also includes a piston cylinder 45 fixed to the inner wall of the filter box 4; a slider 46 is fixed to the outer wall of the piston plate 41; a groove 47 adapted to the slider 46 is opened on the inner wall of the piston cylinder 45; and a return spring 48 is connected between the piston plate 41 and the piston cylinder 45.
[0057] Working principle of this embodiment three:
[0058] Initial state: The return spring 48 pushes the piston plate 41, causing the connecting rod 39 to drive the conical block 40 to press against the inside of the tower wheel 3. The outer wall of the conical block 40 fits seamlessly with the inner wall of the tower wheel 3, and the ball head 36 abuts against the end of the conical block 40.
[0059] Cooling process: The rotation of the tower wheel 3 drives the lug 35 and the ball head 36 to rotate synchronously. The ball head 36 slides into the curved guide plate 44, squeezing the conical block 40 to move towards the piston cylinder 45. The return spring 48 is compressed, and the conical block 40 separates from the inner wall of the tower wheel 3 to form a gap. The coolant in the water tank 2 is drawn into the gap through the filter hole 43. After the ball head 36 rotates past the curved guide plate 44, the return spring 48 rebounds, pushing the conical block 40 to return to its original position. The coolant in the gap is squeezed and discharged through the filter hole 43, forming a piston-type forced pumping circulation.
[0060] Heat dissipation effect: For each rotation of the tower wheel 3, the sliding part 38 completes one liquid intake and discharge cycle. That is, the transmission part 5 drives the circumferential rotation of the tower wheel 3 to drive the sliding part 38 to reciprocate axially, continuously pumping coolant into / out of the tower wheel 3, quickly removing frictional heat, reducing the temperature of the tower wheel 3, avoiding thermal expansion that could lead to a decrease in wire precision, and improving wire drawing stability.
