Description

Technical Field

[0001] The present invention relates to the technical field of steel cords, in particular to a wire position frame used in an electroplating process, and specifically to a wire position frame capable of adjusting the angle direction of steel wire routing for steel cord production and an angle adjustment method. Background Art

[0002] During the electroplating process of steel cord, as the equipment ages and is renovated, the routing width of each process equipment will change. For example, a continuous production routing with 48 wires arranged at the same time, after the old equipment is eliminated, the new equipment is used to optimize the production line. The size of the new equipment is reduced, and the wire spacing between the wires is reduced. After the wires enter the new equipment from the old equipment that has not been upgraded, the wire spacing changes from wide to narrow. When entering the old equipment from the new equipment, the wire spacing changes from narrow to wide. At present, it is necessary to manually adjust the wire spacing of the routing frame according to the process line or change the angle of the wire position to meet the production requirements. Summary of the invention

[0003] The first aspect of the purpose of the present invention is to provide a wire position frame with adjustable wire routing angle direction for steel cord production and an angle adjustment method, which can freely adjust the wire position angle of the wire routing frame to adapt to the wire spacing difference between new and old equipment, so that the steel wire in the electroplating process does not need to be manually adjusted when the process corresponding to the new and old equipment changes, thereby improving the adaptability of the equipment.

[0004] The first aspect of the present invention also provides a quick-release guide wheel for freely adjusting the wiring rack, which can be replaced online.

[0009] A fixed bracket supported by a first supporting leg and a second supporting leg, the fixed bracket being provided with a narrow and long wire-passing groove extending along the bottom edge direction, and a first rotating shaft and a second rotating shaft located on the upper surface of both side ends of the fixed bracket;

[0010] an adjustment plate fixedly mounted to and supported by the upper surface of the third support leg;

[0011] A first rotating bracket supported by the first supporting leg and the third supporting leg, wherein the first end of the first rotating bracket is mounted above the first supporting leg and forms a rotating fit with the first rotating shaft;

[0014] A plurality of evenly spaced guide wheels are disposed above the first rotating bracket and the second rotating bracket, so that a channel for the steel wire to pass through is formed between adjacent guide wheels, and each passing steel wire only contacts one guide wheel, and adjacent guide wheels do not contact each other.

[0015] According to the second aspect of the present invention, the method for adjusting the spacing between steel cord wires comprises the following steps:

[0016] Step 1: Install the line position rack with adjustable line spacing between the processes in the electroplating process that need to change the routing angle. For the narrow spacing process and the wide spacing process with line position differences between the previous and next processes, install the first support leg and the second support leg to the side adjacent to the wide spacing process, and install the third support leg to the side adjacent to the narrow spacing process.

[0017] Step 2: For the process of changing the wire routing from a wide spacing process to a narrow spacing process, or from a narrow spacing process to a wide spacing process, the wire passing angle is adjusted by adjusting the angle between the first rotating bracket and / or the second rotating bracket and the fixed bracket;

[0018] In the adjustment process, firstly, the fasteners at the bottom of the adjustment plate are loosened, so that the first rotating bracket and / or the second rotating bracket are in a state where they can move freely within the angle range defined by the corresponding first notch and the second notch, and then the first rotating bracket and / or the second rotating bracket are rotated respectively with the first rotating axis or the second rotating axis as the center to change their angles relative to the fixed bracket, so that the steel wire enters the next process in a straight line;

[0031] Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed by the present invention are not limited to any implementation. In addition, some aspects disclosed by the present invention can be used alone or in any appropriate combination with other aspects disclosed by the present invention.

[0032] {Example 1}

[0033] Combination Figure 1-7 As shown, a wire positioning frame with adjustable wire routing angle direction for steel cord production according to an embodiment of the present invention includes a first support leg 110, a second support leg 120, a third support leg 130, a fixed bracket 200, a first rotating bracket 310, a second rotating bracket 320 and an adjustment plate 500.

[0034] like Figure 1 , 2 As shown, the bottoms of the first support leg 110, the second support leg 120, and the third support leg 130 are all provided with mounting feet to be fixed to the ground. In the figure, the first support leg 110, the second support leg 120, and the third support leg 130 are all designed with a long rod of a fixed length, such as a steel round long rod structure, to achieve stable support for the entire line rack.

[0035] In other embodiments, the first support leg 110, the second support leg 120, and the third support leg 130 can also be designed as an adjustable / retractable structure, and their lengths can be synchronously adjusted to adjust the height of the entire wire rack to meet the production requirements of steel cords of different specifications / processes.

[0036] In an optional embodiment, the first supporting leg 110, the second supporting leg 120, and the third supporting leg 130 may also be designed into other shapes, such as a square tube shape, to stably support the entire wire rack.

[0037] As a preferred embodiment, the third supporting leg 130 forms an isosceles triangle relationship with the first supporting leg 110 and the second supporting leg 120. The base direction is formed between the first supporting leg 110 and the second supporting leg 120. The waist direction of the triangle is formed between the third supporting leg 130 and the first supporting leg 110, and between the third supporting leg 130 and the second supporting leg 120.

[0038] In other examples, the third supporting leg 130 and the first supporting leg 110 and the second supporting leg 120 may also form an equilateral triangle relationship, which is also applicable to the wiring rack and its adjustment in the embodiment of the present invention.

[0039] Combined with Figure 1 , 2 In the example of FIG. 1 , the fixing bracket 200 supported by the first supporting leg 110 and the second supporting leg 120 is provided with a narrow and long wire groove 210 extending along the bottom side. Figure 2 As shown, a first rotating shaft 220 and a second rotating shaft 230 are respectively disposed on the upper surfaces of both side ends of the fixing bracket 200 .

[0040] The adjustment plate 500 is fixedly mounted to the upper surface of the third supporting leg 130 and supported thereby.

[0041] Combined with Figure 1 , 2 The first rotating bracket 310 is supported by the first supporting leg 110 and the third supporting leg 130 , and the first end thereof is installed above the first supporting leg 110 and forms a rotating fit with the first rotating shaft 220 .

[0042] The second rotating bracket 320 is supported by the second supporting leg 120 and the third supporting leg 130 . The first end of the second rotating bracket 320 is installed above the second supporting leg 120 and forms a rotational fit with the second rotating shaft 230 .

[0043] Combined with Figure 1 , 2 As shown, the adjustment plate 500 has a main body 510 . The main body 510 is provided with a first notch 511 penetrating therethrough for cooperating with the first rotating bracket 310 and a second notch 512 penetrating therethrough for cooperating with the second rotating bracket 320 .

[0044] Combined with Figure 1 , 2 As shown in , 6, the second end of the first rotating bracket 310 is provided with a first guide column 311 extending downward, which is inserted into the first slot 511 and can be operated to slide in the first slot 511; the second end of the second rotating bracket 320 is provided with a second guide column 321 extending downward, which is inserted into the second slot 512 and can be operated to slide in the second slot 512.

[0045] At the same time, a plurality of evenly spaced guide wheels 400 are provided above the first rotating bracket 310 and the second rotating bracket 320, so that a channel for the steel wire 1 to pass through is formed between adjacent guide wheels 400, and each passing steel wire 1 only contacts one guide wheel 400, and adjacent guide wheels 400 do not contact each other.

[0046] Combined with the above embodiments and the attached Figure 1, 2 As shown in 6, in the electroplating process of steel cord production, from one process to another, due to the difference between old and new equipment, the line spacing of each process is different, the groove width of each process is different, and the line spacing of each process is different. For example, taking the wire laying process to the degreasing process as an example, the working groove surface of the previous process is wide, and the working groove surface of the next process is narrow. The design of the wire laying equipment itself has a large spacing between each wire position, and the total width of the arrangement of multiple wire positions (taking a typical 48 as an example) is wide, while the degreasing groove surface does not need to be very wide, and the spacing between each wire is small and the total width is small. The change from a wide spacing process to a narrow spacing process requires adjustment of the routing direction. Through the wire position frame with adjustable wire routing angle direction of the above embodiment of the present invention, the wire routing direction can be quickly changed to allow the steel wire to smoothly enter the narrow spacing process, and vice versa.

[0047] Therefore, the wire positioning frame with adjustable wire routing angle direction of the embodiment of the present invention can realize the free adjustment of the wire routing angle direction, adapt to the different line spacings of new and old equipment, and improve the adaptability of the equipment.

[0048] Combination Figure 1 , 6 As shown, for a narrow pitch process and a wide pitch process with a line position difference between the previous and subsequent processes, the first supporting leg 110 and the second supporting leg 120 are adjacent to one side of the wide pitch process, and the third supporting leg 130 is adjacent to one side of the narrow pitch process.

[0049] As an optional embodiment, the first rotating bracket 310 and the second rotating bracket 320 adopt the same design, and the first rotating bracket 310 or the second rotating bracket 320 can rotate independently relative to the fixed bracket 200 .

[0050] As an optional embodiment, the first notch 511 and the second notch 512 adopt the same design and are axially symmetrically distributed, and are used to limit the rotational motion trajectory and angle range of the first rotating bracket 310 and the second rotating bracket 320 respectively to form a guide during the rotational motion.

[0051] As an optional embodiment, the first guide column 311 of the first rotating bracket 310 is configured to be inserted into the first slot 511 and to be tightened by a first fastener provided at the bottom of the first slot 511 to fix its relative position; before adjusting the first rotating bracket 310, the first fastener is loosened to allow the first guide column 311 to move freely in the first slot 511.

[0052] As an optional embodiment, the second guide column 321 of the second rotating bracket 320 is configured to be inserted into the second slot 512 and to be tightened by a second fastener provided at the bottom of the second slot 512 to fix its relative position; before adjusting the second rotating bracket 320, the first fastener is loosened to allow the second guide column 321 to move freely in the second slot 512.

[0053] As an optional embodiment, the first notch 511 and the second notch 512 are both arc-shaped notches to limit the range of the rotation angle and perform a guiding function, and are more suitable for rotation and sliding than straight notches.

[0054] Combination Figure 2 , 3 As shown, each guide wheel 400 is mounted on the upper surface of the first rotating bracket 310 and the second rotating bracket 320. As an optional embodiment, Figure 4A , 4B As shown, the guide wheel 400 is a quick-release guide wheel.

[0055] Figure 5 The exploded structure of the quick release guide wheel is shown as an example. The quick release guide wheel as shown in the figure includes an inner support column 401, a support shell 402, a first bearing 403, a second bearing 404, an inner guide rod 405, a contact guide wheel 406 and a fastening nut 407.

[0056] Combination Figure 4A , 4B as well as Figure 5 As shown, the bottom of the overall cylindrical inner support column 401 is provided with an extended fixed cylinder, which is installed in the hole on the upper surface of the first rotating bracket 310 or the second rotating bracket 320, and is tightened from the side of the first rotating bracket 310 or the second rotating bracket 320 by screws or bolts to achieve fixed installation.

[0057] The lower end and the upper end of the inner support column 401 are respectively provided with stepped surfaces, and after the aforementioned first bearing 403 and the second bearing 404 are respectively installed and fixed, the whole is sleeved inside the cylindrical support shell 402. That is, the support shell 402 is sleeved outside the circumference of the inner support column 401, and is located on the upper surface of the first rotating bracket 310 and the second rotating bracket 320 at a certain distance, so that the inner support column 401 maintains a fixed relationship with the first rotating bracket 310 and the second rotating bracket 320, and the support shell 402 can rotate freely relative to the inner support column 401 under the action of the bearing, and does not contact the upper surface of the first rotating bracket 310 and the second rotating bracket 320.

[0058] As shown in the figure, based on the design of the step surface at the lower end of the inner support column 401, the lower end of the support shell 402 only covers a portion of the inner support column 401, leaving a certain length uncovered, so that the support shell 402 is relatively suspended on the upper surfaces of the first rotating bracket 310 and the second rotating bracket 320 without contacting them.

[0059] As an optional embodiment, the upper end of the supporting shell 402 is a closed end, and both ends of the inner guide rod 405 are respectively provided with threads, and the threads at the bottom end are tightened to the upper end of the supporting shell 402, so that the two are integrally connected.

[0060] After the inner guide rod 405 passes through the long axis hole in the longitudinal axis direction of the contact guide wheel 406 from the top and extends out, the contact guide wheel 406 is pressed to the upper end surface of the support shell 402 by fitting with the thread on the top of the inner guide rod 405 through the fastening nut 407, forming an integral connection, so that the contact guide wheel 406 and the support shell 402 can rotate synchronously, and the movement of the contact guide wheel 406 along the longitudinal axis direction is limited by the fastening nut 407.

[0061] As an optional embodiment, the contact guide wheel 406 is preferably made of tungsten steel or ceramic, contacts the wire passing through the line, and can be quickly replaced after being worn.

[0065] Step 2: For the process of changing the wire routing from a wide spacing process to a narrow spacing process, or from a narrow spacing process to a wide spacing process, the wire passing angle is adjusted by adjusting the angle between the first rotating bracket 310 and / or the second rotating bracket 320 and the fixed bracket 200;

[0066] In the adjustment process, firstly, the fasteners at the bottom of the adjustment plate 500 are loosened, so that the first rotating bracket 310 and / or the second rotating bracket 320 are in a state where they can move freely within the angle range defined by the corresponding first notch 511 and the second notch 512, and then the first rotating bracket 310 and / or the second rotating bracket 320 are rotated respectively with the first rotating shaft 220 or the second rotating shaft 230 as the center to change their angles relative to the fixed bracket 200, so that the steel wire 2 can smoothly enter the next process;

[0067] After the adjustment is completed, the first rotating bracket 310 and / or the second rotating bracket 320 that has moved is tightened by the fasteners at the bottom of the adjustment plate 500 to fix their relative positions.
