Description
Technical Field
[0001] This utility model relates to the field of steel wire production technology, specifically to a device for identifying broken wires in steel wire cutting. Background Technology
[0002] Steel wire production is a professional manufacturing process that processes metal raw materials into finished steel wire products. It usually uses wire rod (coil) as the initial raw material. First, it undergoes surface treatments such as pickling and phosphating to remove oxide scale and improve lubricity. Then, it is continuously drawn using a wire drawing machine to gradually reduce the diameter of the material to the target specification, while enhancing its strength and toughness. After further processing according to application requirements, the continuously produced extra-long steel wire is finally precisely cut into the specified length according to customer needs. The equipment for cutting steel wire usually has a high-frequency shearing capability. It is usually installed at the end of the wire drawing production line. It drives the cutting unit to perform the shearing work by timed driving. It completes the shearing in an instant with absolute synchronization with the running speed of the steel wire, thereby ensuring that the cut is flat, burr-free, and without pressure loss, so as to achieve fixed-length cutting of the steel wire in operation. However, in actual production, steel wires are susceptible to interference from factors such as abnormal tension, material defects, or equipment vibration, which can cause local damage or signs of imminent breakage on the surface of the steel wire. If a breakage occurs and the system fails to identify the broken wire in time and continues to cut to a fixed length according to the set program, it will result in the production of products that do not meet specifications. Even if the steel wire does not break, these steel wires with potential quality hazards will still be cut and mixed into qualified products, which seriously affects the consistency and reliability of the overall product quality. Therefore, a steel wire breakage identification device is proposed to address the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-10 This utility model provides a technical solution: A wire breakage identification device for cutting steel wire includes an operating table 1. A rotating mechanism 4 is fixedly installed on one side of the operating table 1. A sleeve mechanism 5 is slidably connected to the inner side of the rotating mechanism 4. The rotating mechanism 4 includes a grooved wheel 41 with a sliding groove 42 on its inner side. A spring 43 is fixedly connected to the inner side of the grooved wheel 41. A coil core 44 is fixedly connected to the inner side of the spring 43. A fixing rivet 45 is fixedly inserted through the inner side of the coil core 44. The sleeve mechanism 5 includes a curved tube 51 with a pull ring 52 welded to its outer side and a sliding block 5 welded to its outer side. 3. A compression assembly 54 is fixedly connected to the inner side of the curved tube 51. A clamping assembly 55 is bonded to one end of the curved tube 51. The compression assembly 54 includes a curved rod 541. A connecting spring 542 is welded to the outer side of the curved rod 541. A hollow shell 543 is welded to one end of the connecting spring 542. A ball bearing 544 is rolled inside the hollow shell 543. A limit cone 545 is fixedly connected to the outer side of the hollow shell 543. The clamping assembly 55 includes a rubber ring 551. An air nozzle 552 is fixedly connected to the outer side of the rubber ring 551. A rubber block 553 is bonded and fixed to the inner side of the rubber ring 551.
[0017] As a further implementation of this solution, a cutting mechanism 2 is fixedly installed on one side of the operating table 1. The cutting mechanism 2 includes a positioning plate 21. A motor base 22 is fixedly installed on one side of the positioning plate 21. The motor base 22 is fixed to the housing of the servo motor 23 by bolts. A drive linkage 24 is fixedly connected to one end of the spindle of the servo motor 23. A slide rail 25 is fixedly connected to one side of the positioning plate 21 by screws. A vertical moving plate 26 is connected to one end of the drive linkage 24. A cutter 27 is fixedly installed on one side of the vertical moving plate 26. A positioning block 28 is fixedly connected to one side of the positioning plate 21. Two wire feeding wheels 29 are rotatably installed on one side of the positioning block 28. The motor base 22, slide rail 25, drive linkage 24 and positioning block 28 are all integrated on the positioning plate 21 and directly externally mounted on the operating table 1. This utilizes the redundant space on the side of the operating table 1 without occupying the table surface working area. The drive linkage 24 converts the rotational motion of the spindle of the servo motor 23 into the linear motion of the vertical moving plate 26, thereby realizing the reciprocating motion of the cutter 27 to cut the steel wire. As a further implementation of this solution, a tensioning wheel 3 is rotatably mounted on one side of the operating table 1. The tensioning wheel 3 is positioned above the grooved wheel 41. The sliding groove 42 is shaped like a semi-circle when projected along the axial direction of the grooved wheel 41. The axial length of the spring 43 is equal to the axial length of the grooved wheel 41. The projection of the winding core 44 in the vertical direction is "I"-shaped. The angle between the fixing rivet 45 and the operating table 1 is 90°. The curved tube 51 is arc-shaped. The sliding block 53 is slidably positioned in the sliding groove 42, with the outer side of the sliding block 53 in close contact with the inner side of the sliding groove 42. The tensioning wheel 3, in conjunction with the grooved wheel 41, ensures that the steel wire being conveyed around it is subjected to continuous tension and tightened, thereby ensuring the accuracy during cutting. The special shape of the sliding groove 42 restricts the sliding distance of the sliding block 53. After sliding a certain distance, it will exert a certain force on the grooved wheel 41. The shape of the curved tube 51 can fit well with the grooved wheel 41, thereby improving its stability by combining the design of the outer side of the sliding block 53 and the inner side of the sliding groove 42. Secondly, it can better adapt to the bending generated during the conveying of the steel wire. As a further implementation of this solution, the crank 541 is inserted through the hollow shell 543, and a gap is provided between the outer side of the crank 541 and the inner side of the hollow shell 543. Multiple connecting springs 542 are provided, and the multiple connecting springs 542 are distributed in a ring array in the gap between the crank 541 and the hollow shell 543. One-third of the ball 544 protrudes from the outer side of the hollow shell 543. The connecting springs 542 form radial support between the crank 541 and the hollow shell 543, allowing the hollow shell 543 and the ball 544 to perform dynamic compensation. The ball 544, which is rolled on the hollow shell 543 and one-third protrudes from the outer side of the hollow shell 543, reduces the friction when in contact with the steel wire and avoids the limiting cone 545 from contacting the surface of the steel wire. As a further implementation of this solution, a cavity is provided inside the rubber ring 551, and a curved tube 51 is fixedly connected through the air nozzle 552. Multiple rubber blocks 553 are provided, and the multiple rubber blocks 553 are evenly and equidistantly distributed in a ring array inside the curved rod 541. An anti-slip groove 554 is provided on the side of the rubber block 553 away from the rubber ring 551. By injecting air into the air nozzle 552, the air content in the cavity inside the rubber ring 551 can be changed, thereby changing the shape of the rubber ring 551 and thus changing the clamping force of the rubber block 553 on the steel wire. This, together with the anti-slip groove 554 on one side of the rubber block 553, generates friction on the steel wire. As a further implementation of this solution, a cleaning component 56 is welded to the other end of the curved tube 51. The cleaning component 56 includes a clamping ring 561, a pressure ring 562 slidably disposed inside the clamping ring 561, a compression spring 563 welded to the bottom end of the pressure ring 562, and an elastic clamping plate 564 welded to the upper end of the pressure ring 562. An arc-shaped groove 565 is provided on one side of the elastic clamping plate 564, and bristles 566 are adhered to the side of the elastic clamping plate 564 away from the clamping ring 561. The pressure ring 562 drives the compression spring 563 to deform, thereby changing the contact position between the clamping ring 561 and the elastic clamping plate 564. The arc-shaped groove 565 makes the elastic clamping plate 564 more likely to deform, thereby clamping the steel wire better, and allowing the bristles 566 to clean the surface of the steel wire with greater friction.
[0018] Working process: When using the device, the steel wire to be cut is passed around the tensioning wheel 3, then through the clamping ring 561 and into the curved tube 51. As the steel wire passes through the clamping ring 561, it comes into contact with the bristles 566 attached to one side of the elastic clamping plate 564. When the bristles 566 clean the surface of the steel wire, they are also subjected to the frictional force generated by the steel wire. This causes the bristles 566 to drive the pressure ring 562 downward in the clamping ring 561 through the elastic clamping plate 564. At the same time, the pressure ring 562 presses down on the compression spring 563, thus compressing... Spring 563 is compressed and deformed between hoop 561 and pressure ring 562. The arc groove 565 allows multiple elastic clamps 564 to be better compressed by hoop 561 as pressure ring 562 slides in hoop 561, causing them to deform and contract towards the steel wire. This increases the friction between bristles 566 and the steel wire, improving the cleaning effect on the surface of the cutting steel wire. Then, the steel wire comes into contact with the extrusion assembly 54, at which point the steel wire will compress the ball 544, causing the ball 544 to drive the hollow shell 54. 3. Move the connecting spring 542 between the crank 541 and the hollow shell 543, then pass the steel wire through the clamping assembly 55. By pulling the pull ring 52 fixed on the outside of the curved tube 51, the curved tube 51 and the sliding block 53 are moved. The sliding block 53 slides inside the sliding groove 42, thereby changing the relative position of the curved tube 51 and the grooved wheel 41, and also changing the direction in which the steel wire passes through the sleeve mechanism 5, so that the steel wire is more accurately inserted between the two wire feeding wheels 29 set on one side of the positioning block 28. At this time, The rotation of the upper and lower wire feeding wheels 29 is controlled by the control box set on one side of the operating table 1 to clamp and convey the steel wire. At the same time, the servo motor 23 installed on one side of the motor base 22 is started by connecting an external power source through a wire. This causes the main shaft of the servo motor 23 to rotate and drive the drive linkage 24 to move. The displacement of the drive linkage 24 causes the upper and lower moving plates 26 to slide up and down along the slide rail 25 installed on one side of the positioning plate 21, thereby driving the cutter 27 to move up and down to cut the steel wire conveyed by the wire feeding wheels 29. The first few sections of cut wire are discarded. During subsequent wire feeding, the wire is clamped by the wire feeding wheel 29, and the rotating mechanism 4, the sleeve mechanism 5, and the tensioning wheel 3 are limited, resulting in continuous tension and tightening. This ensures cutting accuracy. Air is injected into the cavity inside the rubber ring 551 through the air nozzle 552, causing the rubber ring 551 to bulge and press the rubber block 553 tightly against the wire. The anti-slip groove 554 on one side of the rubber block 553 increases the friction between it and the wire, allowing the wire to pass through the clamping assembly 55 and be fed by the wire feeding wheel 29. 9. During clamping and conveying, the clamping assembly 55 can be moved by friction. The movement of the clamping assembly 55 causes the curved tube 51 and the sliding block 53 fixed thereto to move. When the sliding block 53 moves, it will be restricted by the sliding groove 42 and exert a force on the grooved wheel 41, causing the grooved wheel 41 to rotate around the fixed rivet 45 and drive the spring 43 to wind up. The setting of the core 44 can ensure that the spring 43 will not move axially during winding, thereby ensuring the stability of the grooved wheel 41 connected to the spring 43. At this time, the section of steel wire located between the wire feeding wheel 29 and the clamping assembly 55 is subjected to the pulling force of the wire feeding wheel 29 clamping and conveying it, as well as the frictional force it experiences when passing through the curved tube 51. If this section of steel wire breaks, the wire feeding wheel 29 will be unable to continue clamping and conveying the steel wire. At the same time, the spring 43 restores its deformation, causing the grooved wheel 41 to rotate and reset, thereby causing the sliding block 53 and the curved tube 51 to move, thus alerting the operator to the wire breakage. Meanwhile, as the steel wire passes through the curved tube 51, it comes into contact with a portion of the protruding and rolling balls 544 on the hollow shell 543, ensuring that its surface does not contact the limiting cone 545. However, if there are minor defects on the surface of the steel wire, the balls 544 will displace upon contact with the defective part of the steel wire surface, thereby changing the pressure of the hollow shell 543 on the connecting spring 542. This causes the deformation of the connecting spring 542 between the curved rod 541 and the hollow shell 543 to change, thus causing the hollow shell 543 to move and drive the limiting cone 545 to move. The tip of the limiting cone 545 will then penetrate the steel wire, restricting the conveying of the steel wire. As a result, the wire feeding wheel 29 can no longer clamp and convey the steel wire. At this point, the defective section of the steel wire can be manually removed. After removal, the preparatory work before cutting can be repeated.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
