Description

Technical Field

[0001] The utility model relates to the technical field of wire take-up machines, in particular to a control device for adjusting the coil diameter of electroplated brass ultra-fine steel wires. Background Art

[0002] During the wire take-up process of electroplated brass ultra-fine steel wires, the steel wires bypass the lead wheel, pass through the wire arranging device, and then enter the winding spool. The winding spool rotates continuously, so as to draw and wind the steel wires on the spool. The function of the wire arranging device is to reciprocate axially along the winding spool, which can guide the steel wires to be evenly wound on the spool, ensuring that the wire arrangement of the steel wires is neat and uniform, as Figure 1 shown. The wire arranging device is a prior art. The wire arranging device is provided with a wire arranging mechanism, and the wire arranging mechanism is two roller cylinders arranged side by side. The steel wires pass through the gap between the two roller cylinders.

[0003] The above-mentioned wire arranging device adopts a wire arranging device for electroplating disclosed in the patent publication number CN215828027U. The gear rotates forward and backward at a certain frequency to drive the rack to move linearly back and forth. Adjusting parts are arranged at both ends of the rack, and then the rack drives the adjusting parts to move together. The adjusting part includes a sleeve, a wire arranging device and an adjusting wheel. The sleeve is in sliding contact with the rack. The wire arranging device is installed on the sleeve. The adjusting wheel is a lead screw structure. The adjusting wheel connects the sleeve and the rack. Rotating the adjusting wheel can drive the sleeve to move along the rack, and then the wire arranging device moves together. The wire arranging device includes a rotating arm, a roller seat and roller cylinders. The roller seat is arranged on the rotating arm. After the two are connected, the cross section is in the shape of "7". Two smooth rod roller cylinders are arranged on the roller seat, as Figure 2 shown.

[0004] Therefore, when the steel wires pass through the wire arranging device, only the two roller cylinders restrict them. The roller cylinders drive the steel wires to shift and arrange the wires, but the steel wires are suspended and not supported. When the steel wires in this state are wound on the winding spool and sampled later, that is, when the steel wires wound on the winding spool are stretched again, there are situations of bending and unevenness and poor straightness, and further the coil diameter of the steel wires is unstable. The coil diameter is one of the indexes for the stable performance of steel wire products. If the coil diameter is unstable, it is difficult to ensure that the quality of the steel wire products meets the requirements, as Figure 3 shown. In the next drawing process, the steel wires with unstable coil diameters have stress concentration and are prone to wire breakage.

[0005] Moreover, when the steel wires pass through the roller cylinders, contact friction will occur between the steel wires and the surface of the roller cylinders, which will cause damage to both. And as the steel wires on the winding spool gradually increase, the position where the steel wires pass through the roller cylinders will also change, that is, the steel wires will move axially on the roller cylinders. The roller cylinder is a cylindrical smooth rod structure, and the roller cylinder cannot restrict it. Furthermore, the steel wires may deviate from the working range of the roller cylinders, so that the wire arranging operation cannot be carried out. Summary of the Invention

[0006] In order to solve the problems that after the steel wire is guided and wound by the existing roller, the coil diameter of the steel wire is unstable and the quality is difficult to guarantee, the present utility model provides a device for adjusting and controlling the coil diameter of electroplated brass ultra-fine steel wire. Through the optimization and transformation of the existing roller, the wear between the steel wire and the wire arranging device is reduced, the axial limitation of the steel wire can be carried out, and at the same time, a wire passing wheel is added. The steel wire can be supported by the wire passing wheel to avoid stress concentration of the steel wire wound on the winding spool, and the subsequent wire drawing quality is improved.

[0007] In order to achieve the above object, the technical solution adopted by the present utility model is as follows:

[0008] The device for adjusting and controlling the coil diameter of electroplated brass ultra-fine steel wire is installed on the roller seat of the wire arranging device and is driven by the wire arranger to move linearly back and forth. It includes a mounting seat, a roller member and a wire passing wheel. The mounting seat includes a bottom plate seat and a vertical plate arranged at a corner on one side of the bottom plate seat.

[0009] The bottom plate seat is horizontally arranged. One side of the bottom plate seat is adjustably connected to the roller seat, which is convenient for changing the position of the bottom plate seat so as to accurately correspond to the lead wheel and well receive the steel wire led out by the lead wheel. On the other side of the bottom plate seat, two roller members are symmetrically arranged. Each roller member includes a core shaft and a chromium-plated roller. The core shaft is detachably connected to the bottom plate seat, which is convenient for the disassembly and assembly of the whole roller member. The chromium-plated roller is rotatably arranged on the core shaft. The diameters of both ends of the chromium-plated roller expand outwards to form a limiting ring, which is convenient for restricting the steel wire and avoiding excessive axial movement of the steel wire along the chromium-plated roller.

[0010] The vertical plate and the roller member are both vertically arranged. The wire passing wheel is vertically and adjustably connected to the vertical plate, which is convenient for adjusting the supporting force of the wire passing wheel on the steel wire. The wire passing wheel is correspondingly arranged between the two roller members. The axial direction of the wire passing wheel is perpendicular to the axial direction of the roller member. After the steel wire bypasses the wire passing wheel, it passes through between the two roller members.

[0011] Further, a clamping groove is opened on the bottom surface of one side of the bottom plate seat. The clamping groove is a rectangular groove and penetrates through the bottom plate seat. The bottom plate seat is clamped to the roller seat through the clamping groove to prevent the bottom plate seat from rotating.

[0012] A horizontal adjustment hole is also opened on one side of the bottom plate seat. The horizontal adjustment hole is a long hole. An installation bolt is inserted into the horizontal adjustment hole. The bottom plate seat is connected to the roller seat through the installation bolt, which is convenient for the disassembly and assembly of the bottom plate seat.

[0013] Further, there is a gap between the two roller members, which is convenient for the steel wire to pass through. The connection line between the centers of the two roller members is arranged along the axial direction of the wire passing wheel.

[0014] The mandrel includes a threaded section, a twisting section, and a mounting section that are integrally formed from bottom to top. The threaded section is threadedly connected to the bottom plate seat, facilitating the disassembly and assembly of the mandrel and the bottom plate seat. The twisting section is hexagonal prism-shaped, facilitating the rotation of the entire mandrel through a tool. The diameter of the twisting section is larger than that of the threaded section. The chrome-plated roller is rotatably arranged outside the mounting section.

[0015] Further, bearings are provided at both ends of the mounting section. The chrome-plated roller is a hollow cylinder. The chrome-plated roller is sleeved outside the mounting section and is rotatably connected to the mounting section through the bearings, improving the smoothness of rotation. A chrome-plated layer is provided on the outer circumferential surface of the chrome-plated roller, reducing the friction between the steel wire and the chrome-plated roller.

[0016] Further, a vertical adjustment hole is provided above the vertical plate. The vertical adjustment hole is a long hole, providing a basis for the position adjustment of the wire guide pulley.

[0017] The wire guide pulley includes a grooved bearing roller, an adjustment bolt, a bushing, and a nut. The adjustment bolt passes through the center of the grooved bearing roller. After the adjustment bolt passes through the vertical adjustment hole, it is connected to the nut. The bushing is also sleeved on the adjustment bolt. The bushing and the nut are tightly abutted against both sides of the vertical plate, facilitating the fixation of the wire guide pulley on the vertical plate.

[0018] Further, a fastening bolt is threadedly connected to the vertical plate. The fastening bolt is vertically arranged and extends downward into the vertical adjustment hole. The fastening bolt radially penetrates the adjustment bolt and is threadedly connected to the adjustment bolt, preventing the adjustment bolt from loosening and shifting up and down. A scale line for indicating the position of adjusting the wire guide pulley is also provided on the surface of the vertical plate, improving the accuracy of adjusting the position of the wire guide pulley.

[0019] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0020] The structure of the present utility model is reasonably designed. By optimizing and improving the original wire arranging device, removing the original two rollers, arranging a mounting seat on the roller seat, and installing a wire guide pulley and two roller members on the mounting seat, a coil diameter adjustment control device is thus formed. After the steel wire bypasses the lead pulley, it passes through the wire guide pulley and then passes between the two roller members and finally winds around the winding spool. Furthermore, during the winding process of the steel wire, the wire guide pulley conveniently provides effective support for the steel wire, preventing it from being suspended. In this way, it is ensured that the steel wire after being re-stretched is basically straight and there is no stress concentration, guaranteeing the stability of the coil diameter of the steel wire and effectively improving the wire drawing quality during the next pass of wire drawing operation.

[0021] The wire passing wheel of the utility model is vertically adjustable and installed on the vertical plate. Adjusting the position of the wire passing wheel can change the supporting force of the wire passing wheel on the steel wire. Under the support of the wire passing wheel, the deformation stress of the steel wire can be avoided. The roller part is composed of a mandrel and a chrome-plated roller. The chrome-plated roller is sleeved outside the mandrel and rotates on the mandrel. At the same time, the surface of the chrome-plated roller has a chrome-plated layer, which can greatly reduce the contact friction between the steel wire and the chrome-plated roller and avoid wear. The V-shaped groove surface of the wire passing wheel also has a chrome-plated layer, which plays the same role. There are limit rings at both ends of the chrome-plated roller, which are convenient for restricting the movement of the steel wire and avoiding the steel wire from deviating from the working range of the roller part along the axial direction of the chrome-plated roller.

Detailed implementation manners

[0034] The following describes in detail the detailed implementation manners of the present utility model in conjunction with the drawings:

[0035] As Figures 4 to 11 shown, the diameter adjustment and control device for electroplated brass ultra-fine steel wire is installed on the roller seat 32 of the wire arranging device 3. The wire arranging device 3 is a part of the wire arranger, and both the wire arranging device 3 and the wire arranger are prior arts. The diameter adjustment and control device is installed on the roller seat 32. When the wire arranger drives the wire arranging device 3 to move linearly back and forth, the diameter adjustment and control device moves together.

[0036] The diameter adjustment and control device is equivalent to replacing the roller in the existing wire arranging device 3, but still retains the swing arm 31 and the roller seat 32. The swing arm 31 and the roller seat 32 are connected and combined to form a "7" shape. Thus, the diameter adjustment and control device can replace the roller and be installed on the roller seat 32. The diameter adjustment and control device includes a mounting seat 7, a roller member 8, and a wire passing wheel 9. The mounting seat 7 is the mounting basis for the roller member 8 and the wire passing wheel 9, as Figure 4 and Figure 5 shown.

[0037] The mounting seat 7 includes a bottom plate seat 71 and a vertical plate 72 provided at a corner on one side of the bottom plate seat 71, as Figure 6 shown. The bottom plate seat 71 is horizontally arranged. The bottom plate seat 71 is a plate body with a certain thickness, with one side thick and the other side relatively thin. The entire diameter adjustment and control device is installed and connected through the bottom plate seat 71 and the roller seat 32. Specifically, one side of the bottom plate seat 71 is adjustably connected to the roller seat 32. The adjustable connection means that the position of the bottom plate seat 71 on the roller seat 32 is adjustable, so as to ensure that the entire diameter adjustment and control device can accurately correspond to the position of the existing lead wheel 1, and thus can smoothly receive the steel wire after passing around the lead wheel 1.

[0038] When the bottom plate seat 71 is installed, the bottom plate seat 71 is connected and fixed to the roller seat 32 in the form of snap connection and bolt connection. Specifically, a clamping groove 10 is provided on the bottom surface of one side of the bottom plate seat 71. The clamping groove 10 is a rectangular groove, and the clamping groove 10 penetrates through the bottom plate seat 71. The bottom plate seat 71 is snap-connected to the roller seat 32 through the clamping groove 10. Furthermore, the bottom plate seat 71 can only move linearly on the roller seat 32 and cannot rotate.

[0039] Meanwhile, a horizontal adjustment hole 11 is also provided on one side of the bottom plate seat 71. The horizontal adjustment hole 11 is an elongated hole, and an installation bolt 12 is inserted into the horizontal adjustment hole 11. The bottom plate seat 71 is connected to the roller seat 32 through the installation bolt 12, and the installation bolt 12 can connect and fix the bottom plate seat 71 and the roller seat 32. After loosening the installation bolt 12, the bottom plate seat 71 is in a loose state, and the position of the bottom plate seat 71 can be adjusted. The adjustment range is within the length range of the horizontal adjustment hole 11.

[0040] The vertical plate 72 is arranged vertically, and the wire passing wheel 9 is connected to the vertical plate 72 in an adjustable up and down manner, that is, the height position of the wire passing wheel 9 is adjustable. When the wire passing wheel 9 is installed, a vertical adjustment hole 13 is provided above the vertical plate 72, and the vertical adjustment hole 13 is an elongated hole. The wire passing wheel 9 includes a grooved bearing roller 91, an adjustment bolt 92, a bushing 93, and a nut 94. The grooved bearing roller 91 adopts a V-shaped grooved bearing roller, and a chromium plating layer 14 is provided on the surface of the V-shaped groove. After chromium plating, the surface of the V-shaped groove is polished, as Figure 7 shown.

[0041] The adjustment bolt 92 passes through the center of the grooved bearing roller 91. After the adjustment bolt 92 passes through the vertical adjustment hole 13, it is connected to the nut 94. At the same time, the bushing 93 is also inserted on the adjustment bolt 92. The bushing 93 is arranged between the vertical plate 72 and the grooved bearing roller 91. After the nut 94 is tightened, the bushing 93 and the nut 94 are tightly abutted against both sides of the vertical plate 72, thereby realizing the installation and fixation of the wire passing wheel 9 on the vertical plate 72. After loosening the nut 94, the entire wire passing wheel 9 can be adjusted up and down along the vertical adjustment hole 13. Changing the position of the wire passing wheel 9 can adjust the supporting force of the wire passing wheel 9 on the steel wire.

[0042] In this embodiment, two roller members 8 are symmetrically arranged on the other side of the bottom plate seat 71, and there is a gap between the two roller members 8 for the steel wire to pass through. That is, after the steel wire bypasses the wire passing wheel 9, it passes through between the two roller members 8. The connection line between the centers of the two roller members 8 is arranged along the axial direction of the wire passing wheel 9. The wire passing wheel 9 is correspondingly arranged between the two roller members 8, and the axial direction of the wire passing wheel 9 is perpendicular to the axial direction of the roller members 8.

[0043] Each roller member 8 includes a mandrel 81 and a chromium-plated roller 82, as Figure 8 and Figure 9The mandrel 81 is detachably connected to the base plate seat 71. The mandrel 81 includes a threaded section 15, a twisting section 16 and a mounting section 17 which are integrally formed from bottom to top. The threaded section 15 is threadedly connected to the base plate seat 71. The twisting section 16 is in the shape of a hexagonal prism. The diameter of the twisting section 16 is larger than that of the threaded section 15. The mandrel 81 can be mounted on the base plate seat 71 by operating the twisting section 16 with a tool.

[0044] The chrome-plated roller 82 is rotatably arranged on the mandrel 81, that is, the chrome-plated roller 82 is rotatably arranged outside the mounting section 17, and the length of the chrome-plated roller 82 matches the length of the mounting section 17. When the chrome-plated roller 82 is installed, bearings are arranged at both ends of the mounting section 17. The chrome-plated roller 82 is a hollow cylinder, and the chrome-plated roller 82 is sleeved outside the mounting section 17. The chrome-plated roller 82 is rotatably connected to the mounting section 17 through the bearings to ensure smooth rotation of the chrome-plated roller 82.

[0045] When the bearings are installed, the bearing located at the lower end of the installation section 17 is the lower bearing 182. The lower bearing 182 is restricted by the shoulder structure at the lower end of the installation section 17 and the lower end of the chrome-plated roller 82, thereby avoiding the axial movement of the lower bearing 182; the bearing located at the upper end of the installation section 17 is the upper bearing 181. The upper bearing 181 is restricted by the shoulder structure at the upper end of the chrome-plated roller 82. At the same time, a limit screw 19 with a gasket is provided at the upper end of the installation section 17. The limit screw 19 is used to restrict the upper bearing 181, thereby avoiding the axial movement of the upper bearing 181.

[0046] A chrome-plated layer 14 is provided on the outer circumference of the chrome-plated roller 82. The chrome-plated layer 14 here is of the same form as the chrome-plated layer 14 on the surface of the V-shaped groove of the wire passing wheel 9. The surface of the chrome-plated roller 82 is chrome-plated and then polished, so that the chrome-plated roller 82 has high hardness and wear resistance. At the same time, the friction coefficient of the chrome-plated layer 14 is small, which greatly reduces the contact wear between the steel wire and the chrome-plated roller 82. The diameters of both ends of the chrome-plated roller 82 are expanded outward to form a limit ring 20, which can limit the axial movement of the steel wire to prevent the steel wire from leaving the operating range of the chrome-plated roller 82.

[0047] The principle of the utility model is as follows: the rollers on the existing wire arrangement device 3 are removed, and the circle diameter adjustment control device is fixed on the roller seat 32. The position of the mounting seat 7 on the roller seat 32 is adjusted by the mounting bolts 12 and the slots 10 to ensure that the wire wheel 9 and the existing wire guide wheel 1 are accurately matched, and then the mounting bolts 12 are tightened. After the steel wire passes around the wire guide wheel 1, it passes between the wire guide wheel 9 and the two chrome-plated rollers 82, and finally winds around the winding I-shaped wheel 2, such as Figure 10 shown.

[0048] During the process of winding the steel wire on the take-up spool 2, the wire guiding pulley 9 supports the steel wire to prevent the steel wire from hanging in the air. The steel wire is displaced and arranged in a row while being carried in the wire guiding pulley 9, and the straight state of the steel wire is ensured during this process. When the steel wire contacts the chrome-plated roller 82, the friction coefficient is small, and at the same time, the limiting rings 20 at both ends of the chrome-plated roller 82 can limit the steel wire. Thus, after the steel wire wound on the take-up spool 2 is re-stretched, it is basically straight, which can effectively control the coil diameter of the steel wire, ensure the stability of the coil diameter, and further, there is no stress concentration in the steel wire. In the next drawing operation, the drawing quality is greatly improved.

[0049] In order to optimize the product structure and improve the reliability of the installation of the wire guiding pulley 9, a fastening bolt 21 is threadedly connected to the vertical plate 72. The fastening bolt 21 is vertically arranged, and the fastening bolt 21 extends downward into the vertical adjustment hole 13. The fastening bolt 21 radially penetrates through the adjusting bolt 92 and is threadedly connected to the adjusting bolt 92, as Figure 11 shown.

[0050] The wire guiding pulley 9 is installed and fixed to the vertical plate 72 through the clamping action of the bushing 93 and the nut 94. To prevent the loosening of the clamping, the fastening bolt 21 and the adjusting bolt 92 are connected again. In this way, the adjusting bolt 92 can be prevented from moving up and down in the vertical adjustment hole 13, that is, on the premise that the nut 94 is loosened, the fastening bolt 21 can drive the adjusting bolt 92 to move, and then change the height position of the wire guiding pulley 9. A scale line 22 for indicating the position of adjusting the wire guiding pulley 9 is also provided on the surface of the vertical plate 72. The wire guiding pulley 9 adjusts its position according to the scale line 22, and the supporting force of the wire guiding pulley 9 on the steel wire can be changed. The position adjustment of the wire guiding pulley 9 is made more precise by the fastening bolt 21, and the supporting force of the wire guiding pulley 9 on the steel wire can be more accurately controlled.

[0051] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
