Description

Technical Field

[0001] This utility model relates to the field of steel wire shaping technology, and in particular to a mold device for shaping steel wire for optical fibers. Background Technology

[0002] The shaping die device for optical fiber steel wire is an important piece of equipment in the field of steel wire manufacturing technology. It is mainly used for processing optical fiber steel wire ropes to ensure that the shape and size of the steel wire meet specific requirements. The shaping die device for optical fiber steel wire typically consists of multiple components, including a support body, a shaping body, and a steel wire positioning mechanism. These components work together to clamp, guide, and process the steel wire, thereby producing standard-compliant optical fiber steel wire.

[0003] Existing steel wire molds cannot adjust the size of the mold hole during actual use, thus making it impossible to manufacture steel wires of different diameters, which limits their practicality.

[0004] An existing patent (publication number: CN213103825U) discloses a special mold for shaping steel wire for optical fibers. It includes a base plate with a mold mounted on top of the base plate. The mold includes a first pressure plate and a second pressure plate, with the second pressure plate positioned on top of the first pressure plate and hinged to it. A cavity is formed between the first and second pressure plates. A rotating assembly, including a disc, is located at one end of the mold. By rotating the disc, through holes of different diameters on the disc are aligned with one end of the horizontal section of the cavity. Then, a limiting bolt is rotated to fix the disc, ensuring that the through holes on the disc are precisely aligned with one end of the cavity. This allows for the production of steel wires of different diameters, making it more practical in actual use.

[0005] To address the aforementioned issues, existing patents offer solutions that allow for the production of steel wires of varying diameters by rotating a disc to align the through-holes of different diameters with one end of the horizontal section of the cavity. However, these solutions cannot straighten the steel wires during processing, resulting in uneven stress distribution during use and stress concentration, which reduces service life and stability. Summary of the Invention

[0006] The purpose of this invention is to provide a mold device for shaping steel wire for optical fibers, which can compress the steel wire and straighten it. Furthermore, by turning the adjusting screw on the fixed block, the mounting plate can be driven to move vertically with the help of the guide rod, thereby adjusting the distance between the adjusting wheel and the fixed wheel. This facilitates the straightening operation of steel wires of different diameters, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold device for shaping steel wire for optical fibers, comprising a fixed base, two fixed rods fixed on the upper surface of the fixed base, a fixed plate fixed at the upper end of each of the two fixed rods, a mounting frame welded to one side of the fixed plate, a straightening mechanism for straightening the steel wire provided inside the mounting frame, and a conveying mechanism for conveying the steel wire installed on one side of the mounting frame;

[0008] The straightening mechanism includes a fixed wheel, which is rotatably connected to the inside of the mounting frame via a bearing. An adjusting wheel is arranged below the fixed wheel, and both ends of the adjusting wheel are rotatably connected to a mounting plate via a bearing. An adjusting screw is rotatably connected to the lower surface of the mounting plate via a bearing.

[0009] Preferably, the outer surface of the adjusting screw is threaded with a fixing block that is fixedly connected to the mounting bracket, and the lower surface of the mounting plate is fixed with two guide rods that penetrate the interior of the mounting bracket.

[0010] Preferably, the conveying mechanism includes a drive motor, which is fixed to one side of the mounting frame by bolts, and the drive motor's power output shaft is fixed with a drive roller.

[0011] Preferably, a driven roller is disposed below the driving roller, and both ends of the driven roller are rotatably connected to movable blocks via bearings.

[0012] Preferably, the movable block has a mounting rod that is fixedly connected to the mounting frame passing through its interior, and the outer surface of the mounting rod is fitted with a spring that abuts against the movable block.

[0013] Preferably, the lower surface of the fixing plate is fixed with an upper mold by bolts, and a lower mold is placed below the upper mold.

[0014] Preferably, the lower surface of the lower mold is fixed with a mold base by bolts, and the lower end of the mold base is connected to a hydraulic cylinder fixed inside the fixed base.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The straightening mechanism can compress the steel wire to straighten it. The adjusting screw on the fixed block can be turned to drive the mounting plate to move vertically with the help of the guide rod, thereby adjusting the distance between the adjusting wheel and the fixed wheel, which is convenient for straightening steel wires of different diameters.

[0017] 2. The conveying mechanism can convey steel wire, and the mounting rod on the movable block can push the driven roller closer to the driving roller under the action of the spring, thereby pressing the steel wire and effectively reducing slippage during steel wire conveying.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A mold device for shaping steel wire for optical fiber includes a fixed base 1, two fixed rods 2 fixed on the upper surface of the fixed base 1, a fixed plate 3 fixed at the upper end of each of the two fixed rods 2, a mounting frame 4 welded to one side of the fixed plate 3, a straightening mechanism for straightening the steel wire inside the mounting frame 4, and a conveying mechanism for conveying the steel wire installed on one side of the mounting frame 4.

[0028] The straightening mechanism includes a fixed wheel 5, which is rotatably connected to the inside of the mounting frame 4 via bearings. An adjusting wheel 51 is arranged below the fixed wheel 5. Both ends of the adjusting wheel 51 are rotatably connected to a mounting plate 52 via bearings. An adjusting screw 53 is rotatably connected to the lower surface of the mounting plate 52 via bearings. A fixing block 54, which is fixedly connected to the mounting frame 4, is threaded onto the outer surface of the adjusting screw 53. Two guide rods 55, which penetrate the inside of the mounting frame 4, are fixed to the lower surface of the mounting plate 52. The conveying mechanism includes a drive motor 6, which is fixed to one side of the mounting frame 4 via bolts. An active roller 61 is fixed to the power output shaft of the drive motor 6. A driven roller 62 is arranged below the active roller 61. Both ends of the driven roller 62 are rotatably connected to a movable block 63 via bearings. An mounting rod 64, which is fixedly connected to the mounting frame 4, passes through the inside of the movable block 63. A spring 65, which abuts against the movable block 63, is sleeved on the outer surface of the mounting rod 64.

[0029] By adopting the above technical solution, before using the optical fiber steel wire shaping mold device, the fixed base 1 is first placed in a suitable position. During use, the steel wire to be processed is first passed between the active roller 61 and the driven roller 62. The drive motor 6 on the mounting frame 4 drives the active roller 61 to rotate, thereby conveying the steel wire. Furthermore, through the mounting rod 64 on the movable block 63, under the elasticity of the spring 65, the driven roller 62 can be pushed closer to the active roller 61, thereby pressing the steel wire. To effectively reduce slippage during wire conveying, the wire passes between the fixed wheel 5 and the adjusting wheel 51. The fixed wheel 5 and the adjusting wheel 51 work together to compress and straighten the wire. Furthermore, by turning the adjusting screw 53 on the fixed block 54, the mounting plate 52 can move vertically with the help of the guide rod 55, thereby adjusting the distance between the adjusting wheel 51 and the fixed wheel 5. This facilitates straightening operations for wires of different diameters and improves practicality.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the lower surface of the fixing plate 3 is fixed with an upper mold 7 by bolts, the lower mold 8 is placed below the upper mold 7, the lower surface of the lower mold 8 is fixed with a mold base 9 by bolts, and the lower end of the mold base 9 is connected to a hydraulic cylinder 10 fixed inside the fixing base 1.

[0031] By adopting the above technical solution, when the steel wire is conveyed between the upper mold 7 and the lower mold 8, the conveying will stop. The hydraulic cylinder 10 set on the fixed base 1 drives the mold seat 9 to move, thereby driving the lower mold 8 to move closer to the upper mold 7 to process the steel wire. The fixed rod 2 can play a guiding role to prevent the mold seat 9 from deviating when it moves. The fixed plate 3 can enhance the stability of the device.

[0032] Working principle: The steel wire to be processed is passed between the driving roller 61 and the driven roller 62. The drive motor 6 drives the driving roller 61 to rotate, thereby conveying the steel wire. Under the elasticity of the spring 65, the driven roller 62 is pushed closer to the driving roller 61, thus compressing the steel wire. During conveying, the steel wire passes between the fixed wheel 5 and the adjusting wheel 51. With the cooperation of the fixed wheel 5 and the adjusting wheel 51, the steel wire is squeezed, thereby straightening the steel wire. The adjustment is set on the fixed block 54. When the screw 53 is turned, the mounting plate 52 can be driven to move vertically with the help of the guide rod 55, thereby adjusting the distance between the adjusting wheel 51 and the fixed wheel 5. When the steel wire is conveyed between the upper mold 7 and the lower mold 8, the conveying will stop. The hydraulic cylinder 10 set on the fixed base 1 drives the mold seat 9 to move, thereby driving the lower mold 8 to move closer to the upper mold 7 to process the steel wire. The fixed rod 2 can play a guiding role to prevent the mold seat 9 from deviating when it moves.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
