Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing machines, and particularly to a built-in wire drawing powder filtering system for a wire drawing machine. Background Art

[0002] A wire drawing machine, also known as a metal wire drawing device, can perform industrial processes such as surface wire drawing and polishing on metal components; the metal components after wire drawing and polishing will have better rust prevention performance and will also be more beautiful.

[0003] When the wire drawing machine performs abrasive polishing on metal objects, the metal objects will first pass under the grinding rollers of the wire drawing machine. The high-speed rotating grinding rollers contact the surface of the metal objects. During the wire drawing process, a large amount of wire drawing dust and debris will appear. In the prior art, there is a lack of filtration and collection of this part of the wire drawing dust. The untreated dust will enter the next processing link together with the metal objects after wire drawing and grinding. If it continuously adheres to the surface of the metal objects, it will affect the surface flatness and various properties of the metal objects. Therefore, we propose a built-in wire drawing powder filtering system for a wire drawing machine. Summary of the Invention

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains. The words such as "including" used herein are intended to mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0030] In view of the problems existing in the prior art, an embodiment of the present invention provides a built-in wire drawing powder filtering system for a wire drawing machine, as Figure 1 and Figure 2 shown. The built-in wire drawing powder filtering system for the wire drawing machine includes a wire drawing machine housing 1, and a wire drawing mechanism 2, a wire body 3 and a filtering mechanism 4 disposed in the wire drawing machine housing 1. After the wire drawing process of the wire body 3 by the wire drawing mechanism 2, it passes through the filtering mechanism 4 for the filtering process. The structure of the wire drawing mechanism 2 can be a commonly used structure in the market and will not be elaborated here. Among them, the filtering mechanism 4 includes a filtering box 45 fixedly arranged on the inner bottom wall of the wire drawing machine housing 1. The setting of the filtering box 45 is used to ensure that there are no dust and burrs on the wire body 3 coming out from the left side. And a first filtering component 41, a second filtering component 42 and a holding pipe 43 which are disposed in the filtering box 45 and sleeved outside the wire body 3. The first filtering component 41 is used to remove the burrs on the surface of the wire body 3. The setting of this embodiment is not limited to removing the burrs on the surface of the wire body 3. For example, in another embodiment, the first filtering component 41 can also remove the solid substances solidified on the surface of the wire body 3. The second filtering component 42 is used to remove the dust on the surface of the wire body 3. The setting of the holding pipe 43 can keep the surface of the wire body 3 clean. It should be noted that the setting of this embodiment is not limited to removing dust. During operation, after the wire body 3 undergoes the deburring process of the first filtering component 41 and the surface dust removal process of the second filtering component 42, it enters the holding pipe 43 in a clean state and is output outside the filtering box 45 in the clean state under the holding of the holding pipe 43.

[0031] In this embodiment, the filtering mechanism 4 is provided to remove burrs or solids on the surface of the wire body 3, and can also remove dust or powder on the surface of the wire body 3. At the same time, it can ensure that the surface of the wire body 3 is output outside the filter box 45 in a clean state, thus effectively preventing dust from entering the next processing step together with the polished and drawn metal object, and further avoiding affecting the surface flatness and various properties of the metal object.

[0032] In one embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, the first filtering component 41 includes a first filtering cylinder 411 with its opening facing right; and a first fixing rod 412 fixedly arranged on the outer top wall of the first filtering cylinder 411, with the upper end of the first fixing rod 412 fixedly connected to the inner top wall of the filter box 45. An annular knife 413 is arranged inside the first filtering cylinder 411. The cavity of the annular knife 413 is in a horn-shaped structure, and the blade of the annular knife 413 is arranged on the right side, so as to better cut off the burrs on the surface of the wire body 3 moving from right to left. The annular knife 413 is movably sleeved outside the wire body 3, and the blade of the annular knife 413 is in contact with the surface of the wire body 3. Such a setting can ensure that when the annular knife 413 cuts, all the burrs on the wire body 3 can be cut off, preventing the time-consuming and laborious problems caused by adding subsequent burr removal processes. A connecting rod 414 is fixedly arranged on the outer side wall of the annular knife 413. It can be understood that the left upper end of the annular knife 413 is connected to the connecting rod 414, and the connecting rod 414 is inclined upward, so as to more effectively provide horizontal thrust and pulling force for the annular knife 413.

[0033] In one example, as Figure 4 shown, the free end of the connecting rod 414 is fixedly connected to the outer side wall of a rectangular frame 415. The rectangular frame 415 is slidably arranged in a chute 416. The chute 416 is fixedly arranged on the inner top wall of the first filtering cylinder 411. The setting of the chute 416 is used to support the rectangular frame 415, so that the rectangular frame 415 can stably move left and right in the horizontal direction. Two straight racks 417 are symmetrically arranged inside the rectangular frame 415. Specifically, in Figure 4In the example, a straight rack 417 is connected to the inner top wall and the inner bottom wall of the rectangular frame 415 respectively; and a spur gear 418 is arranged between the two straight racks 417. The spur gear 418 meshes with the two straight racks 417 alternately. The spur gear 418 is fixedly sleeved on the driving end of the driving motor 419. The driving motor 419 is fixedly arranged on the inner side wall of the first filter cylinder 411, or the driving motor 419 can also be fixedly arranged on the outer side wall of the first filter cylinder 411; a plurality of first blanking holes (not labeled) are formed at the bottom of the first filter cylinder 411. The arrangement of the first blanking holes can output the cut burrs to the outside of the first filter cylinder 411. There is a gap between two adjacent first blanking holes, and the size of the gap is less than 0.1 mm. Such an arrangement can ensure that the cut burrs can all move to the outside of the first filter cylinder 411 through the first blanking holes, avoiding deposition in the first filter cylinder 411.

[0034] In this embodiment, the structural design of the first filter assembly 41 is reasonable, and it can effectively remove the burrs on the surface of the wire body 3. It should be noted that the cutting process can be carried out synchronously while the wire body 3 moves to the left, so that there is no need to stop the machine for the cutting process, thereby greatly improving the preparation efficiency. Specifically, with the completion of the preparation of the wire body 3, the driving motor 419 starts to operate. The start of the driving motor 419 will drive the spur gear 418 to rotate clockwise. The clockwise rotation of the spur gear 418 meshes with the upper straight rack 417 at this time, so that the rectangular frame 415 will be driven to move to the right through the upper straight rack 417, and then the annular knife 413 will be driven to move to the right through the rectangular frame 415 and the connecting rod 414. When the wire body 3 moves to the left into the annular knife 413, the annular knife 413 moving to the right will cut off the burrs on the surface of the wire body 3. As the spur gear 418 continues to move, the spur gear 418 will rotate to mesh with the lower straight rack 417, so that the rectangular frame 415 will be driven to move to the left through the lower straight rack 417, and the annular knife 413 will be driven to move to the left through the rectangular frame 415 and the connecting rod 414 (it should be noted that when the annular knife 413 moves to the left, in order to ensure the smooth progress of the cutting process and avoid the burrs being missed and not cut, the moving speed of the wire body 3 to the left should be less than the moving speed of the annular knife 413 to the left). The structural design of this embodiment is reasonable. The leftward movement of the annular knife 413 is on the wire body 3 after the burrs have been cut off. When the spur gear 418 meshes with the upper straight rack 417 again, the annular knife 413 will move to the right again to cut off the burrs on the wire body 3. In this embodiment, the annular knife 413 can move left and right cyclically, which can not only avoid the problem that the single-direction movement amplitude of the annular knife 413 is too large and requires a larger space, but also improve the working efficiency through cyclic cutting.

[0035] In one implementation, as Figure 4As shown, the first filtering component 41 further includes a guiding and supporting component 4110 with one end connected to the outer sidewall of the rectangular frame 415 and the other end fixedly connected to the inner sidewall of the first filtering cylinder 411. The guiding and supporting component 4110 includes a guiding support rod 41101, a guiding support cylinder 41102, and a guiding support spring 41103. The guiding support rod 41101 is movably inserted into the guiding support cylinder 41102. The guiding support spring 41103 is wound around the guiding support rod 41101, and one end of the guiding support spring 41103 is fixedly connected to the sidewall of the guiding support rod 41101, and the other end of the guiding support spring 41103 is fixedly connected to the outer sidewall of the guiding support cylinder 41102. In this embodiment, the setting of the guiding and supporting component 4110 can not only play a role in guiding and supporting the movement of the rectangular frame 415, enabling the rectangular frame 415 to only move in the horizontal direction, but also provide a restoring force for the restoring process of the rectangular frame 415.

[0036] In one embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, the second filtering component 42 includes a second filtering cylinder 421 disposed in the filtering box 45, and the opening of the second filtering cylinder 421 faces right; and a second fixing rod 422 fixedly provided on the outer top wall of the second filtering cylinder 421, with the upper end of the second fixing rod 422 fixedly connected to the inner top wall of the filtering box 45. The second filtering cylinder 421 is fixedly inserted into the side plate (left bottom plate) of the first filtering cylinder 411, and a plurality of cleaning brushes 423 are arranged in the second filtering cylinder 421. One end of the cleaning brush 423 is in contact with the wire body 3, and the other end of the cleaning brush 423 is fixedly connected to the inner sidewall of the first support tube 424. There are multiple groups of cleaning brushes 423, and multiple groups of cleaning brushes 423 are all inclined downward. In this way, when the wire body 3 moves to the left, the rotating lower end of the cleaning brush 423 can be tangent to the surface of the wire body 3, so as to lift the dust deposited on the surface of the wire body 3, thereby achieving a more effective cleaning effect. Multiple groups of cleaning brushes 423 are arranged at equal intervals along the axial direction of the wire body 3.

[0037] In one embodiment, as Figure 6As shown, the first support tube 424 is fixedly inserted into the second support tube 425. A third support tube 426 is fixedly sleeved outside the second support tube 425. The third support tube 426 is movably arranged in a movable groove (not labeled), and the movable groove is opened on an arc-shaped plate 427. The arc-shaped plate 427 is fixedly connected to the inner side wall of the second filter cartridge 421. The arcs of the arc-shaped plate 427, the third support tube 426, the second support tube 425, and the first support tube 424 are all the same; on opposite side walls of the third support tube 426, fourth support tubes 428 are fixedly arranged. The fourth support tubes 428 are movably arranged in annular grooves 429, and the annular grooves 429 are opened on the arc-shaped plate 427, the fourth support tubes 428 and the annular grooves 429; a plurality of second discharge holes (not labeled) are opened at the bottom of the second filter cartridge 421; the arrangement of the second discharge holes is used to discharge the dust cleaned from the surface of the wire body 3, avoiding the deposition of the cleaned dust at the bottom of the second filter cartridge 421. It should be noted that there is a gap between adjacent two second discharge holes, and the size of the gap is less than 0.1 mm. With such a setting, it can ensure that all the dust is discharged outside the second filter cartridge 421. During operation, the rotation of the first support tube 424 will drive the cleaning brush 423 to rotate, and the rotation of the cleaning brush 423 will clean the dust on the surface of the wire body 3.

[0038] In one embodiment, as Figure 2 , Figure 3 and Figure 6 shown, the wire drawing machine internal wire drawing powder filtering system further includes a blocking mechanism 5. The setting of the blocking mechanism 5 is used to block the gap between the holding tube 43 and the wire body 3 to ensure that the wire body 3 enters the holding tube 43 in a clean state; the blocking mechanism 5 includes a horizontal section 51 movably inserted into the holding tube 43. The holding tube 43 is fixedly inserted into the side plate (left bottom plate) of the second filter cartridge 421, and the holding tube 43 is fixedly inserted into the side wall (left side plate) of the filter box 45. The blocking mechanism 5 further includes a vertical section 52 connected to the horizontal section 51. The vertical section 52 is arranged in contact with the inner side wall of the second filter cartridge 421. Of course, in other embodiments, the vertical section 52 and the second filter cartridge 421 can also be fixedly connected; and an arc-shaped surface 53 provided on the vertical section 52. The arc-shaped surface 53 and the horizontal section 51 are respectively arranged on both sides of the vertical section 52. The setting of the arc-shaped surface 53 guides the dust to fall, avoiding the deposition of the dust on the upper surface of the arc-shaped surface 53; through holes are opened on both the vertical section 52 and the horizontal section 51. The wire body 3 is movably inserted into the through holes. There is a gap between the wire body 3 and the side wall of the through hole, and the size of the gap is less than 0.1 mm. The gap between the wire body 3 and the through hole can be ignored.

[0039] In one embodiment, asFigure 7 As shown in the figure, the wire drawing machine's built-in wire drawing powder filtering system further includes a linkage mechanism 6. The setting of the linkage mechanism 6 can link the left and right movement of the rectangular frame 415 and the rotational movement of the second support tube 425, eliminating the need to add two sets of power sources. On the one hand, this can reduce production costs, and at the same time, it can improve the high-efficiency performance of the equipment. The linkage mechanism 6 includes a first bevel gear 61. A through hole 62 is provided in the middle of the first bevel gear 61. The wire body 3 passes through the through hole 62. The first bevel gear 61 is fixedly connected to the side wall of the second support tube 425. The first bevel gear 61 meshes with a second bevel gear 63. The second bevel gear 63 is fixedly sleeved outside the inner spiral tube 64. The inner spiral tube 64 is fixedly arranged on the rotating shaft 65. The rotating shaft 65 is rotatably arranged on the inner side wall of the first filter cylinder 411. A screw rod 66 is threadedly inserted into the inner spiral tube 64. The screw rod 66 is movably sleeved outside the push-pull rod 67. The push-pull rod 67 is fixedly arranged on the outer side wall of the rectangular frame 415.

[0040] During operation, since the screw rod 66 is threadedly inserted into the inner spiral tube 64, the screw rod 66 will cause the inner spiral tube 64 to rotate whether it moves to the left or to the right. Specifically, when the rectangular frame 415 moves to the right, it will pull the screw rod 66 to move to the right through the push-pull rod 67. The rightward movement of the screw rod 66 will cause the inner spiral tube 64 to rotate. The rotation of the inner spiral tube 64 will drive the second support tube 425 to rotate through the second bevel gear 63 and the first bevel gear 61. The rotation of the second support tube 425 will drive the cleaning brush 423 to rotate through the first support tube 424. The rotation of the cleaning brush 423 will remove the dust on the surface of the wire body 3.

[0041] After the dust and burrs are cleaned from the wire body 3, in order to better and timely collect the dust and burrs, in one embodiment, as Figure 2 shown, the filtering mechanism 4 further includes a collection component 44 for collecting dust or burrs. The collection component 44 includes a collection tube 441. The collection tube 441 is fixedly arranged in the filter box 45 through a collection rod 445. The collection tube 441 is located directly below the first filter cylinder 411 and the second filter cylinder 421, and a collection conveyor belt 442 is located directly below the collection tube 441. The collection conveyor belt 442 is sleeved outside the driving roller shaft 443. The driving roller shaft 443 is arranged in the filter box 45 through a driver (the driver can be a driving motor). The collection component 44 further includes a collection box 444 arranged below (which can be understood as arranged in the lower right) the collection conveyor belt 442. The collection box 444 is fixedly arranged on the inner bottom wall of the filter box 45.

[0042] During operation, the cleared dust and burrs respectively fall into the collection pipe 441 through the second discharge hole and the first discharge hole under the action of their own gravity, and then fall along the collection pipe 441 onto the collection conveyor belt 442. As the collection conveyor belt 442 rotates, they are finally carried into the collection box 444 for collection. It should be noted that this process does not require manual control and can automatically collect dust and burrs.

[0043] During the process of dust cleaning, some of it will escape into the air. In one embodiment, as Figure 8 , Figure 9 and Figure 10 shown, the wire drawing machine's built-in wire drawing powder filtration system further includes a suction mechanism 7. The suction mechanism 7 includes a driving mechanism, which is interconnected with the second rotating rod 75. The second rotating rod 75 is rotatably inserted into the collection pipe 441.

[0044] In this embodiment, the combined structure of the second rotating rod 75, the rotating shaft 76, the rotating fan blades 77, and the arc-shaped groove 78 has the suction function of a suction pump. Therefore, as this combined structure moves, a downward suction force can be generated, so that all the dust can be sucked into the collection pipe 441 and discharged through the collection pipe 441 onto the collection conveyor belt 442. In this way, through the setting of the suction mechanism 7, all the dust can be discharged.

[0045] In one embodiment, as Figure 9As shown, the driving mechanism includes a rubber roller 71 that is mutually opposed to the collecting conveyor belt 442, the rubber roller 71 is fixedly sleeved outside the first rotating rod 72, the first rotating rod 72 is rotatably set on the support plate 73, the support plate 73 is fixedly set on the outer wall of the collecting pipe 441, the first rotating rod 72 is fixedly sleeved with a first flywheel outside the fixed sleeve, the second rotating rod 75 is fixedly sleeved with a second flywheel outside the fixed sleeve, and the first flywheel and the second flywheel are rolled with a connecting conveyor belt 74 outside the rolling sleeve. The structural design of the driving mechanism in this embodiment is reasonable, and no external power source is required, which can reduce production costs and improve the high efficiency performance of the equipment; when working, the rotation of the collecting conveyor belt 442 will drive the rubber roller 71 to rotate, and the rotation of the rubber roller 71 will drive the rotating shaft 76 and the rotating fan blade 77 to rotate through the first rotating rod 72, the connecting conveyor belt 74, the first flywheel and the second flywheel to achieve the function of sucking dust.

[0046] In order to prevent further dust dispersion, in one embodiment, Figure 11 As shown, the wire drawing machine built-in wire drawing powder filtering system also includes a dust hood 8, which is fixedly arranged on the upper end of the collecting tube 441, and the inner cavity of the collecting tube 441 is connected to the inner cavity of the dust hood 8, and the dust hood 8 is arranged outside the first filter component 41 and the second filter component 42, and the dust hood 8 is an arch bridge structure. The setting of the dust hood 8 in this embodiment can confine the scattered dust within the range of the dust hood 8, and the structure of the dust hood 8 is reasonably designed. The lower end, left end and right end of the dust hood 8 are all provided with openings, and the left and right ends of the dust hood 8 are arranged relative to each other and arranged in the axial direction of the wire body 3, so that the lower end opening of the dust hood 8 is used to transport dust and burrs into the collecting tube 441, and the left and right end openings of the dust hood 8 are used to suck air into the dust hood 8, so that the dust hood 8 can be used to collect dust and burrs. During operation, the downward suction force generated by the suction mechanism 7 will cause the air to enter the dust hood 8 from the left and right openings of the dust hood 8. In this way, during the flow of air, dust can be prevented from escaping to the outside of the dust hood 8. At the same time, the air entering the dust hood 8 and the air containing dust in the dust hood 8 will be sucked downward along the collecting pipe 441 by the suction mechanism 7. This will prevent the dust from escaping to the outside of the dust hood 8 and at the same time ensure the cleanliness of the air in the dust hood 8.
