Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and more specifically, it relates to a drawing device for steel cord. Background Technology

[0002] Steel cord is a high-strength, high-toughness metal wire product made from high-quality high-carbon steel wire rod through multiple processes such as drawing and twisting. Its surface is usually coated to enhance its adhesion to rubber. With its excellent tensile strength, fatigue strength and dimensional stability, steel cord can effectively improve the structural strength, load-bearing capacity and service life of rubber products.

[0003] Currently, traditional steel cord drawing devices typically employ a single-stage or double-stage tower wheel structure, with the tower wheel as the main transmission component. The tower wheel surface has annular grooves of different diameters, and the wire winds within these grooves, gaining traction as the tower wheel rotates. During operation, after the wire is drawn out from the unloading device, it first passes through a drawing die with a specific aperture. Under the traction of the tower wheel, it is forced through the die hole. Because the die aperture is smaller than the original diameter of the wire, the wire undergoes plastic flow under pressure, and its diameter is compressed to the size of the die aperture. In contrast, the single-stage tower wheel structure completes one drawing deformation cycle using only one set of tower wheels and one set of dies.

[0004] However, traditional drawing devices mostly rely on single-stage or double-stage tower wheel structures. The coordination between each stage of the tower wheel and the die requires a large driving force to achieve the plastic deformation of the wire. Especially for steel cord with a large diameter, a high-power drive motor is often required to provide traction force, which not only increases the energy consumption of the equipment, but also increases the electricity cost in the production process.

[0005] To address the above problems, this utility model proposes a steel cord pulling device. Utility Model Content

[0017] In summary, this application includes at least one of the following beneficial technical effects: By setting a drive motor to rotate the first, second, third, and fourth take-up shafts, the steel cord first passes through the second guide die and then winds onto the second take-up shaft. After winding onto the second take-up shaft, it passes through the first circular guide die on the first guide die and is guided onto the first take-up shaft, where the steel cord is shaped and rapidly thinned. After being pulled by the first and second take-up shafts, it first passes through the fourth guide die and then winds onto the fourth take-up shaft. After being wound onto the fourth take-up shaft, it passes through the second circular guide die on the third guide die and is guided onto the third take-up shaft. After being pulled by the third take-up shaft, it is guided onto the traction wheel for winding. By reducing the lever arm between the first, second, third, and fourth take-up shafts and by setting the first and second circular guide dies to plastically position the steel cord, the motor can pull larger-sized steel cords at low power.

[0025] 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.

[0026] Please see Figure 1-7 The present invention provides the following technical solution: To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] See Figure 1 and 2A steel cord drawing device includes a drawing body 1, a drive mechanism 2 mounted on the drawing body 1, and a first take-up shaft 3, a second take-up shaft 4, a third take-up shaft 5, and a fourth take-up shaft 6 equidistantly arranged on one side of the drawing body 1. A first wire guide assembly 7 is arranged between the first take-up shaft 3 and the second take-up shaft 4, and a second wire guide assembly 8 is arranged between the third take-up shaft 5 and the fourth take-up shaft 6.

[0028] The pulling body 1 provides the installation position. The drive mechanism 2 is installed on the pulling body 1. The drive mechanism 2 drives the first take-up shaft 3, the second take-up shaft 4, the third take-up shaft 5 and the fourth take-up shaft 6 to rotate, thereby pulling the steel cord. The first wire guide assembly 7 and the second wire guide assembly 8 restrict the position of the steel cord and control the elongation rate by restricting the position of the steel cord through the first wire guide assembly 7 and the second wire guide assembly 8.

[0029] See Figure 3 The drawing body 1 includes a drawing housing 11, on which a traction wheel 12 is provided. The drive mechanism 2 includes a drive motor 21, and the output end of the drive motor 21 is connected to an output component 22. On one side of the output component 22, a third driven component 25, a second driven component 24, and a first driven component 23 are arranged in sequence. On the other side of the output component 22, a fourth driven component 26 is arranged. One end of the fourth driven component 26 drives the traction wheel 12 to rotate, and the fourth driven component 26 drives the first take-up shaft 3 to rotate. The third driven component 25 drives the first take-up shaft 3 to rotate, and the second driven component 24 drives the third take-up shaft 5 to rotate. The other end of the first driven component 23 drives the fourth take-up shaft 6 to rotate. A transmission belt 27 is connected between the output component 22 and the first driven component 23, the second driven component 24, the third driven component 25, and the fourth driven component 26, and the drive is transmitted through the transmission belt 27. The drawing housing 11 provides a rotational position for the traction wheel 12. The drive motor 21 is installed on one side of the drawing housing 11. The output end of the drive motor 21 penetrates the drawing housing 11 and connects to the output assembly 22 inside. The output assembly 22 and the first driven assembly 23 transmit rotational force through the transmission belt 27. The first driven assembly 23 and the third driven assembly 25 transmit rotational force through the transmission belt 27. The first driven assembly 23 and the second driven assembly 24 transmit rotational force through the transmission belt 27. The third driven assembly 25 and the fourth driven assembly 26 transmit rotational force through the transmission belt 27. The third driven assembly 25 rotates synchronously with the second take-up shaft 4. The fourth driven assembly 26 rotates synchronously with the first take-up shaft 3. The second driven assembly 24 rotates synchronously with the third take-up shaft 5. The first driven assembly 23 rotates synchronously with the fourth take-up shaft 6. The transmission belt 27 is a belt with a toothed internal structure.

[0030] Output assembly 22 includes an output shaft 221, the output shaft of drive motor 21 is connected to output shaft 221, and an output gear 222 is mounted on output shaft 221. First driven assembly 23 includes a first driven shaft 231, on which a first driven gear 232, a second driven gear 233, and a third driven gear 234 are sequentially mounted. A transmission belt 27 is fitted onto output gear 222 and the first driven gear 232. The output shaft 221 drives the output gear 222 to rotate. The output gear 222 is mounted on the first driven gear 232 via the transmission belt 27. The rack inside the transmission belt 27 meshes with the output gear 222 and the first driven gear 232. When the output shaft 221 rotates, it drives the output gear 222 to rotate. The output gear 222 transmits the rotational power to the first driven shaft 231. The rotation of the first driven assembly 23 synchronously drives the second driven gear 233, the third driven gear 234, the traction wheel 12 and the fourth take-up shaft 6 to rotate.

[0031] The third driven assembly 25 includes a third driven shaft 251, on which a fifth driven gear 252 and a sixth driven gear 253 are sequentially mounted, and a transmission belt 27 is fitted onto the fifth driven gear 252 and the second driven gear 253.

[0032] When the second driven gear 233 rotates, the rotational power of the second driven gear 233 is transmitted to the fifth driven gear 252 through the transmission belt 27. The rotation of the fifth driven gear 252 drives the third driven shaft 251 to rotate, which in turn drives the sixth driven gear 253 and the second take-up shaft 4 to rotate.

[0033] The second driven assembly 24 includes a second driven shaft 241, a fourth driven gear 242 mounted on the second driven shaft 241, and a transmission belt 27 sleeved on the fourth driven gear 242 and the third driven gear 234.

[0034] When the third driven gear 234 rotates, it transmits the rotational power to the fourth driven gear 242 through the transmission belt 27. The rotation of the fourth driven gear 242 drives the second driven shaft 241 to rotate, which in turn drives the third take-up shaft 5 to rotate.

[0035] The fourth driven assembly 26 includes a fourth driven shaft 261, a seventh driven gear 262 is mounted on the fourth driven shaft 261, and a transmission belt 27 is sleeved on the seventh driven gear 262 and the sixth driven gear 253.

[0036] When the sixth driven gear 253 rotates, it transmits the rotational power to the seventh driven gear 262 through the transmission belt 27. The rotation of the seventh driven gear 262 drives the fourth driven shaft 261 to rotate, and the fourth driven shaft 261 drives the first take-up shaft 3 to rotate.

[0037] The output shaft 221, the second driven shaft 241, the third driven shaft 251 and the fourth driven shaft 261 are all rotatably arranged inside the drawing housing 11. Through their cooperation, they drive the first take-up shaft 3, the second take-up shaft 4, the third take-up shaft 5 and the fourth take-up shaft 6 to rotate. One end of the first driven shaft 231 is rotatably installed inside the drawing housing 11, and the other end penetrates the drawing housing 11 and is connected to the traction wheel 12. A support plate 13 is provided below the traction wheel 12. A positioning platform 16 and a wire feeding fixing platform 14 are installed on the side wall of the drawing housing 11. An I-beam wheel 15 is rotatably installed on the wire feeding fixing platform 14.

[0038] The support plate 13 helps reduce friction between the traction wheel 12 and the drawing housing 11, preventing the traction wheel 12 from getting too close to the drawing housing 11 and causing wear on the steel cord. The positioning table 16 is used to position the take-up position of the steel cord. The wire feeding fixing table 14 provides rotation conditions and installation position for the I-beam wheel 15. The steel cord is pulled over the I-beam wheel 15 to avoid contact with the side wall of the drawing housing 11.

[0039] The height of the first take-up spool 3 is greater than that of the second take-up spool 4, and the height of the third take-up spool 5 is greater than that of the fourth take-up spool 6. The first take-up spool 3, the second take-up spool 4, the third take-up spool 5, and the fourth take-up spool 6 all have a third take-up spool 5 layer for pulling the wire. Through the staggered setting of the first take-up spool 3 and the second take-up spool 4, the second layer of the second take-up spool 4 corresponds to the first layer of the first take-up spool 3. When the wire is fed in, the steel cord is first wound to the first layer of the second take-up spool 4. Through the staggered setting of the third take-up spool 5 and the fourth take-up spool 6, the second layer of the fourth take-up spool 6 corresponds to the first layer of the third take-up spool 5. This reduces the lever arm size when pulling the wire and avoids excessively low elongation.

[0040] See Figure 4 The first wire guiding assembly 7 includes a first mold platform 71 and a second wire guiding mold body 77 fixed on the drawing housing 11. The first mold platform 71 is equipped with a first wire guiding mold body 74 and a second wire guiding mold body 77. The first wire guiding mold body 74 is provided with first mold pits 75 at equal intervals. A first circular wire guiding mold 76 is placed in each of the first wire guiding mold bodies 74. The structure of the second wire guiding mold body 77 is the same as that of the first mold pits 75. The first mold platform 71 is located between the first take-up shaft 3 and the second take-up shaft 4, providing an installation position for the first wire guide mold body 74 and the first mold pit 75. The position of the passing steel cord is restricted by the first circular wire guide mold 76 inside the first wire guide mold body 74. The first circular wire guide mold 76 is a small-sized mold that shapes the steel cord and quickly refines it.

[0041] A first wire guide fixing block 72 is installed on one side of the first mold platform 71. A first wire guide wheel 73 is rotatably installed on the first wire guide fixing block 72. A first support column 78 is installed at the end of the second wire guide mold body 77 away from the first mold platform 71. A second wire guide wheel 79 is rotatably installed on the first support column 78.

[0042] The first wire guide fixing block 72 provides an installation position for the first wire guide wheel 73, and the rotation of the first wire guide wheel 73 conveys the steel cord that has just entered. The first support column 78 provides an installation position for the second wire guide wheel 79, and the rotation of the second wire guide wheel 79 conveys the steel cord that has been pulled by the first take-up shaft 3.

[0043] See Figure 5 The second wire guiding assembly 8 includes a second mold platform 81. A third wire guiding mold body 84 is installed on the second mold platform 81. Second mold pits 85 are equidistantly arranged on the third wire guiding mold body 84. Second circular wire guiding molds 86 are placed in the first three second mold pits 85 near the drawing housing 11 on the third wire guiding mold body 84. The structure of the fourth wire guiding mold body 87 is the same as that of the second mold pits 85.

[0044] The second mold platform 81 is located between the third take-up shaft 5 and the fourth take-up shaft 6, providing an installation position for the third wire guide mold body 84 and the second mold pit 85. The second circular wire guide mold 86 inside the third wire guide mold body 84 restricts the position of the passing steel cord. The second circular wire guide mold 86 is used for rear-end drawing to avoid center cracks caused by a decrease in elongation.

[0045] A second wire guide fixing block 82 is installed on one side of the second mold platform 81. A third wire guide wheel 83 is rotatably installed on the second wire guide fixing block 82. A second support column 88 is installed at the end of the fourth wire guide mold body 87 away from the second mold platform 81. A fourth wire guide wheel 89 is rotatably installed on the second support column 88.

[0046] The second guide wheel 82 provides an installation position for the third guide wheel 83. The rotation of the third guide wheel 83 conveys the steel cord pulled by the first take-up shaft 3. The second support column 88 provides an installation position for the fourth guide wheel 89. The rotation of the fourth guide wheel 89 conveys the steel cord pulled by the third take-up shaft 5. The steel cord pulled by the third take-up shaft 5 is then sent to the traction wheel 12 for winding.

[0047] See Figure 6 and Figure 7By setting a drive motor 21 to drive the first take-up shaft 3, the second take-up shaft 4, the third take-up shaft 5, and the fourth take-up shaft 6 to rotate, the steel cord first passes through the second guide die 77 and then winds onto the second take-up shaft 4. After being wound onto the second take-up shaft 4, it passes through the first circular guide die 76 on the first guide die 74 and is guided onto the first take-up shaft 3 to shape and quickly refine the steel cord. After the first take-up shaft 3 and the second take-up shaft 4 are pulled, the steel cord first passes through the fourth guide die 87 and then winds onto the fourth take-up shaft 6. After being wound onto the fourth take-up shaft 6, the wire passes through the second circular guide die 86 on the third guide die body 84 and is guided onto the third take-up shaft 5. After the third take-up shaft 5 has finished pulling, the wire is guided onto the traction wheel 12 for winding. By reducing the lever arm between the first take-up shaft 3, the second take-up shaft 4, the third take-up shaft 5 and the fourth take-up shaft 6 and by setting the first circular guide die 76 and the second circular guide die 86, the steel cord is plastically positioned, thereby enabling the motor to pull larger specifications of steel cord in a low-power state.

[0048] During winding, the steel cord passes through the fourth guide wheel 89, enters the center hole of the positioning platform 16, is pulled over the I-beam wheel 15, and is finally wound up by the traction wheel 12. The size of the traction wheel 12 can be changed according to requirements. Traction wheels at different positions can be set on the drawing housing 11 to make the wire routing more convenient.

[0049] When the steel cord has a thicker diameter, it is pulled using a smaller diameter layer through the first take-up shaft 3 and the second take-up shaft 4. The third take-up shaft 5 and the fourth take-up shaft 6 also use a smaller diameter layer for pulling. Since using a smaller diameter layer changes the pulling speed ratio, the size of the traction wheel 12 is reduced according to the speed ratio. This allows a small-power motor to be used to pull the steel cord when it has a thicker diameter.

[0050] When the steel cord has a thinner diameter, it is pulled using a larger diameter layer through the first take-up shaft 3 and the second take-up shaft 4. The third take-up shaft 5 and the fourth take-up shaft 6 also use a larger diameter layer for pulling. Since using a larger diameter layer will change the pulling speed ratio, the size of the traction wheel 12 is increased according to the speed ratio. This allows a small-power motor to be used to pull the steel cord when it has a thinner diameter.

[0051] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
