Description

Technical Field

[0001] The invention relates to the technical field of iron chain processing, and in particular to an iron wire feeding winding drum device for processing metal iron chains. Background Art

[0002] Most iron chains are made by cutting iron wires with machines, and processing iron wires of equal lengths so that the iron wires are processed into iron rings of the same size and connected to each other to achieve a processed iron chain. When the iron wires are transported, two feed trays are usually placed close to each other and the iron wires are placed in the middle. The rotation of the two feed trays drives the iron wires to move and cut and process them.

[0003] Because the iron wire is processed through some devices, the surface of the iron wire is subjected to uneven force, which will destroy the internal molecular structure and cause strain hardening, which may form hard protrusions on the surface of the iron wire, and the iron wire may undergo oxidation reaction in an environment with oxygen to generate rust. This rust may appear on the surface of the iron wire in the form of hard foreign matter. When the feed wheel on the winding reel directly contacts the hard foreign matter or protrusion on the surface of the iron wire, it will cause a stress concentration effect, and stress concentration will not only affect the structural strength of the feed wheel, but may also induce the generation of cracks, thereby affecting the fatigue life and reliability of the feed wheel. In addition, the feed wheel conveys the iron wire intermittently. When the feed wheel stops and the feed wheel continues to rest on the hard foreign matter or protrusion on the surface of the iron wire, the stress concentration will increase, and the fatigue damage of the feed wheel will be accelerated, thereby accelerating the damage of the feed wheel, which will affect the efficiency and stability of conveying the iron wire.

[0040] An arc frame 14 is fixed on the outer arc surface of the first arc-shaped linkage plate 13, the inner concave surface of the arc frame 14 faces the first arc-shaped linkage plate 13, and the outer arc surface of the arc frame 14 faces the center of the housing 10. A first reset spring 16 is fixed between the side of the clamping column facing the arc frame 14 and the inner concave surface of the arc frame 14, which is used to support the clamping column, thereby facilitating the reset of the clamping column.

[0041] refer to Figure 1-Figure 7As shown, the arc frame 14 is provided with a first linkage mechanism 20 and a second linkage mechanism 30. The clamping columns in the upward or downward state can exert pressure on the adjacent clamping columns, so as to keep the clamping columns stably conveying the wire.

[0042] The first linkage mechanism 20 includes a connecting member 21 fixed on the top of the clamping column, both sides of the connecting member 21 have inner concave surfaces, and the inner concave surfaces are triangular, and the middle part of the connecting member 21 has an opening 22, and the inner bottom wall of the opening 22 is fixed with a first arc block 23, and the first arc block 23 is semicircular, and the interior of the plurality of arc frames 14 is provided with a first arc member 24, and the first arc member 24 is composed of two arc plates, and there is an arc plate between the three clamping columns, and the two arc plates are connected with the clamping column in the middle of the first arc linkage plate 13. The arc plates are centrally symmetrical, and one end of the two arc plates close to the clamping column in the middle of the first arc-shaped linkage plate 13 is the head end, and the other end of the two arc plates is the tail end. The arc plates cooperate with the first arc block 23 to drive the corresponding clamping column to move downward, so as to facilitate the clamping column to clamp and transport the iron wire. Support frames 29 are fixed on both sides of the first arc member 24, and the inner wall of the support frame 29 is rotatably connected with a rotating shaft 210. The rotating shaft 210 is used to squeeze the first arc block 23, so as to facilitate the corresponding clamping column to move downward and apply pressure to the iron wire for squeezing.

[0043] Two third groove groups 25 are provided on the arc frame 14, and the two third groove groups 25 are arranged in an arc shape on the side wall of the arc frame 14, and the two third groove groups 25 are symmetrical with the clamping column in the middle of the first arc-shaped linkage plate 13 as the center. The third groove group 25 is composed of two first limiting slide grooves, and the two first limiting slide grooves are symmetrically provided on the outer wall of the arc frame 14 with the arc frame 14 as the center. First limiting sliders 26 are fixed on both sides of the arc plate, and the first limiting sliders 26 are slidably connected to the corresponding first limiting slide grooves. The first limiting slider 26 cooperates with the first limiting slide groove to limit the arc plate, thereby maintaining the stability of the arc plate when sliding. A second return spring 27 is fixed between one side of the first limiting slider 26 and the inner wall of the first limiting slide groove, which is used to support the first limiting slider 26, so as to facilitate the corresponding arc plate to be reset.

[0044] A limiting assembly 28 is provided on each of the multiple first arc-shaped members 24. The limiting assembly 28 includes an L-shaped arc-shaped member 280 provided on the arc plate, and two L-shaped arc-shaped members 280 are arranged alternately on the arc frame 14, and the two L-shaped arc-shaped members 280 are respectively fixed on the corresponding arc plates, and a second limiting slider 282 is fixed to the bottom of the two L-shaped arc-shaped members 280. Positioning grooves 281 are provided on the outer arc surfaces of the two arc plates, and the two second limiting sliders 282 are respectively slidably connected to the corresponding positioning grooves 281. The second limiting slider 282 cooperates with the positioning groove 281 to push the corresponding arc plate, and can drive the clamping column to move downward to apply pressure on the iron wire, thereby keeping the iron wire stably transported to the processing site for processing.

[0045] Since the initial position of the second limit slider 282 is against the inner wall of the corresponding positioning slot 281, and a driving source is installed inside the mounting box, it can drive the outer shell 10 to rotate, and make the two outer shells 10 rotate in opposite directions. When the iron wire is conveyed on the outer shell 10, one end of the clamping column extending out of the outer shell 10 is against the surface of the iron wire. At this time, the three clamping columns will synchronously slide toward the arc frame 14 and compress the first return spring 16, and the rotating shaft 210 is located between the bottom and top ends of the corresponding first arc block 23.

[0046] When the clamping member 15 presses against the hard foreign matter or protrusion on the surface of the iron wire, the clamping column pressing against the hard foreign matter or protrusion will move up and slide toward the arc frame 14, and the clamping column in the upward state will compress the first return spring 16, and the first arc block 23 can push the arc plate through the corresponding rotating shaft 210, and the arc plate squeezes the first arc block 23 corresponding to it through the rotating shaft 210, thereby driving the clamping column that is not in contact with the hard foreign matter or protrusion to be pressed down, which can prevent the clamping column from continuously contacting the hard foreign matter or protrusion on the surface of the iron wire, resulting in a concentrated force effect caused by excessive pressure, thereby reducing fatigue damage to the clamping column.

[0047] When the clamping column located in the middle of the first arc-shaped linkage plate 13 presses against the hard foreign matter or protrusion on the surface of the iron wire, the clamping column moves up and slides toward the arc frame 14, and the first arc block 23 inside the clamping column will push the corresponding rotating shafts 210 on both sides, and the rotating shafts 210 drive the connected arc plates to slide toward the adjacent clamping columns. At this time, the L-shaped arc member 280 close to the inside of the outer shell 10 drives the second limit slider 282 to slide in the corresponding positioning groove 281, and the L-shaped arc member 280 close to the circular baffle 11 also drives the second limit slider 282 to slide in the corresponding positioning groove 281.

[0048] The rotating shaft 210 at the rear end of the arc plate will press against the corresponding first arc block 23 and slide toward its top, and the connecting piece 21 will drive the connected clamping column to move downward, thereby increasing the pressure strength of the clamping column on the iron wire. When the clamping column is separated from the protrusion on the surface of the iron wire, the first return spring 16 can drive the connected clamping column to reset, and at the same time, the second return spring 27 drives the connected arc plate to reset through the first limit slider 26.

[0049] When the clamping column close to the circular baffle 11 presses against the hard foreign matter or protrusion on the surface of the wire, the clamping column moves up and slides toward the arc frame 14, and the first arc block 23 inside the clamping column pushes the rotating shaft 210 at the tail end of the corresponding arc plate, and the rotating shaft 210 drives the connected arc plate to slide toward the middle of the arc frame 14, and at the same time, the arc plate drives the connected L-shaped arc member 280 to slide toward the inside of the housing 10, and at this time, the L-shaped arc member 280 pushes the other side through the second limit slider 282. The arc plate slides toward the interior of the outer shell 10, and the arc plate pushes the first arc block 23 corresponding to it through the rotating shaft 210 on its tail end. The first arc block 23 drives the clamping column close to the interior of the outer shell 10 to move downward, thereby increasing the clamping force of the clamping column on the iron wire. When the clamping column is separated from the hard foreign matter or protrusion on the surface of the iron wire, the first return spring 16 can drive the connected clamping column to reset, and at the same time, the second return spring 27 drives the connected arc plate to reset through the first limit slider 26.

[0050] When the clamping column away from the circular baffle 11 presses against the hard foreign matter or protrusion on the surface of the wire, the clamping column moves up and slides toward the arc frame 14, and the first arc block 23 inside the clamping column pushes the rotating shaft 210 at the tail end of the corresponding arc plate, and the rotating shaft 210 drives the connected arc plate to slide toward the middle of the arc frame 14, and at the same time, the arc plate drives the connected L-shaped arc member 280 to slide toward the circular baffle 11. At this time, the L-shaped arc member 280 pushes the arc plate on the other side to slide toward the circular baffle 11 through the second limiting slider 282, and the arc plate pushes the corresponding arc plate through the rotating shaft 210 on its tail end. The first arc block 23 drives the clamping column close to the circular baffle 11 to move downward, thereby increasing the clamping force of the clamping column on the iron wire. When the clamping column is separated from the hard foreign matter or protrusion on the surface of the iron wire, the first reset spring 16 can drive the connected clamping column to reset. At the same time, the second reset spring 27 drives the connected arc plate to reset through the first limit slider 26. Through the cooperation between the three clamping columns, when one of the clamping columns moves upward, pressure can be applied to the other two clamping columns, so that the clamping columns can stably transport the iron wire and prevent uneven acceptance of the iron wire during transportation.

[0051] The second linkage mechanism 30 includes side columns 31 fixed on both sides of the arc plate, and a second arc linkage plate 33 is fixed on the outer surface of the side column 31. The second arc linkage plate 33 is used to drive the clamping column to move downward, so as to maintain the stability of the clamping column in clamping and conveying the wire. A sliding column 35 is fixed on the side of the second arc linkage plate 33 away from the connecting piece 21.

[0052] Two fourth groove groups 34 are provided on the outer wall of the arc frame 14, and the two fourth groove groups 34 are symmetrical with the clamping column in the middle of the first arc-shaped linkage plate 13 as the center. The fourth groove group 34 is composed of two second limiting slide grooves, and the two second limiting slide grooves correspond to the head end and the tail end of the arc plate respectively, and the sliding columns 35 at the head end and the tail end of the arc plate are slidably connected to the corresponding second limiting slide grooves. The sliding columns 35 cooperate with the second limiting slide grooves to limit the second arc-shaped linkage plate 33, thereby maintaining the stability of the second arc-shaped linkage plate 33 when sliding. A side plate 36 is fixed on the clamping column in the middle of the first arc-shaped linkage plate 13, and first semicircular blocks 37 are fixed on both sides of the side plate 36. Second semicircular blocks 38 are fixed on the clamping columns on both sides of the first arc-shaped linkage plate 13, and the arc surface of the second semicircular block 38 faces the clamping column in the middle of the first arc-shaped linkage plate 13.

[0053] Since the two fourth groove groups 34 correspond to the two arc plates, the second limiting slide groove is composed of an arc segment and an oblique segment, and the oblique segment is directed downward, and the oblique segments of the second limiting slide groove located in the middle of the arc frame 14 are all toward the side plate 36, and the oblique segments of the second limiting slide grooves on both sides of the arc frame 14 are all toward its ends.

[0054] Since the surface of the iron wire is uneven, the surface of the iron wire will have some depressions. When the clamping column in the middle of the first arc-shaped linkage plate 13 moves to the depression on the iron wire surface, the first return spring 16 in a compressed state will drive the clamping column located at the depression to move down and reset. At the same time, the two first semicircular blocks 37 on the side plate 36 respectively push the corresponding second arc-shaped linkage plates 33, and the second arc-shaped linkage plates 33 drive the connected arc plates to slide toward the adjacent clamping columns. At this time, the two arc plates move away from each other, and the adjacent clamping columns are driven downward by the first arc block 23 to apply pressure to the iron wire. At this time, the sliding column 35 at the head end of the arc plate will slide to the depth of the corresponding second limiting slide groove arc section, and the sliding column 35 at the tail end of the arc plate It will slide to the inside of the corresponding second limiting slide groove oblique section, and the sliding column 35 located inside the oblique section will drive the connected second arc-shaped linkage plate 33 to move downward, and the downward-moving second arc-shaped linkage plate 33 will not contact the corresponding second semicircular block 38, so that the clamping column that moves down to the depression on the wire surface can exert force on the adjacent clamping column, so as to keep the wire under the stable conveying force of the clamping column. When the clamping column that is moving downward moves to the flat surface of the wire again, the clamping column moves upward to compress the connected first return spring 16, and the arc plate is reset by the connected second return spring 27, and at the same time, the sliding column 35 inside the oblique section of the second limiting slide groove is reset to the inside of its arc section.

[0055] When one of the clamping posts on the two sides of the first arc-shaped linkage plate 13 moves to the recessed position on the wire surface, the first return spring 16 in the compressed state will drive the clamping post located at the recessed position to move down and reset, and at the same time, the clamping post will push the second arc-shaped linkage plate 33 at the tail end of the arc-shaped plate through the connected second semicircular block 38. At this time, the second arc-shaped linkage plate 33 drives the arc-shaped plate to slide toward the clamping post in the middle of the first arc-shaped linkage plate 13, and at the same time, the sliding post 35 at the head end of the arc-shaped plate slides into the oblique section of the second limiting slide groove, and the sliding post 35 at the tail end of the arc-shaped plate slides into the deep arc section of the second limiting slide groove, and the rotating shaft 210 at the head end of the arc-shaped plate can drive the clamping post in the middle of the first arc-shaped linkage plate 13 to move downward through the corresponding first arc-shaped block 23, and the arc-shaped plate can drive the other arc-shaped plate to slide through the limiting assembly 28, so that the clamping post in the downward moving state can apply pressure to the other two clamping posts, thereby maintaining the force of the iron wire being stably conveyed by the clamping post.

[0056] refer to Figure 2 , Figure 3 Figure 4 and Figure 8 As shown, the first arc-shaped linkage plate 13 is provided with an upward movement mechanism, which can drive the clamping column to move upward, thereby preventing the bottom of the clamping column from continuously squeezing hard foreign matter or protrusions on the surface of the wire to cause wear and deformation due to stress extrusion.

[0057] The upward movement mechanism includes three groups of upward movement components 40 arranged on the first arc-shaped linkage plate 13, and the three upward movement components 40 correspond to the three clamping columns respectively. The upward movement components 40 include two support plates 41 fixed on the top of the first arc-shaped linkage plate 13, and a connecting port 42 is provided on the support plate 41. A T-shaped sliding block 43 is slidably connected inside the connecting port 42. A third reset spring 44 is fixed between the step surface of the T-shaped sliding block 43 and the support plate 41, which is used to support the T-shaped sliding block 43, so as to facilitate the reset of the T-shaped sliding block 43. A triangular plate 45 is fixed on the top of the T-shaped sliding block 43, and third semicircular blocks 46 are fixed on the outer walls of both sides of the clamping column. The third semicircular block 46 is located below the T-shaped sliding block 43, and a circular column 47 is fixed on the inner wall of the circular baffle 11, and a protrusion 48 is fixed on the outer surface of the circular column 47.

[0058] When the clamping column is against the hard foreign matter or protrusion on the surface of the iron wire, the clamping column moves up, and the third semicircular block 46 can push the T-shaped sliding block 43 to slide to the side away from the clamping column. At this time, the T-shaped sliding block 43 stretches the third return spring 44. When the clamping column moves up, the third semicircular block 46 is located on the surface of the triangular plate 45, and the third return spring 44 drives the third semicircular block 46 to reset. At this time, the triangular plate 45 moves to the bottom of the third semicircular block 46, and the triangular plate 45 can press against The third semicircular block 46 moves upward, and at the same time, the third semicircular block 46 drives the connected clamping column to move upward to the extreme position, thereby driving the clamping column away from the hard foreign matter or protrusions on the surface of the wire, thereby preventing the clamping column from continuously pressing against the hard foreign matter or protrusions on the surface of the wire and causing fatigue damage. When the outer shell 10 continues to rotate around its axial direction, the connecting piece 21 of the clamping column in the upward state will press against the protrusion 48, and the protrusion 48 can press against the clamping column to slide toward the inner wall of the outer shell 10 for reset.
