Description

Technical Field

[0001] This utility model relates to the field of cable bow stranding machine guide plate processing technology, and in particular to a cable bow stranding machine guide plate rolling device. Background Technology

[0002] The winch is a key component of a cable pantograph winch. Traditional winches are primarily made of spring steel, which suffers from drawbacks such as easy deformation, large amplitude, and heavy weight during high-speed operation. Currently, the main material for winches is carbon fiber, which offers advantages such as high rigidity, resistance to deformation, small amplitude, and light weight. Cable pantograph winches generate significant centrifugal force during operation. To ensure uniform rotation throughout the entire circumference and prevent it from being affected by centrifugal force, precise guide plates are required during use to guarantee the quality of the stranding. When wear on the guide plates affects the stranding quality, simply replace the guide plates.

[0003] Currently, the manufacturing of guide plates mostly employs stamping equipment for forming. Stamping is a production technology that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing the sheet metal to undergo direct deformation and plastic deformation or separation within the die, thereby obtaining product parts with specific shapes, dimensions, and properties. However, the dies used in stamping are generally specialized; a complex part may require several sets of dies to form, and the die manufacturing requires high precision and advanced technology. Designing and manufacturing a dedicated set of dies for guide plates is economically inefficient, occupies a stamping press, which is expensive, and poses safety risks to operators during processing. Therefore, there is an urgent need for a cable bow stranding machine guide plate rolling device to solve the above-mentioned technical problems. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cable bow stranding guide plate rolling device, comprising:

[0007] The machine base is equipped with a feed inlet and a discharge outlet;

[0008] The shaping assembly includes a first shaft and a second shaft, wherein the first shaft is disposed at the feed inlet and the second shaft is disposed at the discharge outlet;

[0009] A first rolling mechanism is disposed within the machine base and located on the side of the first shaft away from the feed inlet. The first rolling mechanism includes a first wheel, a second wheel, and a drive assembly. The first wheel and the second wheel are vertically spaced apart from each other on the machine base and are both rotatable relative to the machine base. The drive assembly is used to drive the first wheel to rotate. The first wheel has a first cylindrical surface and an annular convex arc surface, and the second wheel has a second cylindrical surface and an annular concave arc surface. The second cylindrical surface mates with the first cylindrical surface, and the annular concave arc surface mates with the annular convex arc surface.

[0010] The second rolling mechanism is located inside the machine base and between the first rolling mechanism and the second shaft. The second rolling mechanism includes a third wheel and a fourth wheel. The third wheel and the fourth wheel are arranged vertically at intervals on the machine base and can rotate relative to the machine base. The third wheel has a third cylindrical surface and the fourth wheel has a fourth cylindrical surface that mates with the third cylindrical surface. Both the third wheel and the fourth wheel have grooves.

[0011] In some possible implementations, in the first wheel and the second wheel, one of them has a first limiting protrusion on each of its opposite sides along the axial direction, and the other has a first clearance groove on each of its opposite sides along the axial direction, with the first clearance groove facing the first limiting protrusion; in the third wheel and the fourth wheel, one of them has a second limiting protrusion on each of its opposite sides along the axial direction, and the other has a second clearance groove on each of its opposite sides along the axial direction, with the second clearance groove facing the second limiting protrusion.

[0012] In some possible implementations, the first wheel is connected to the base via a pivot shaft that passes through the side wall of the base and extends out of the base. The drive assembly includes a sleeve and an electric wrench. The sleeve is detachably connected to the extended end of the pivot shaft, and the electric wrench is inserted into the sleeve to drive the sleeve to rotate, thereby causing the pivot shaft to rotate.

[0013] In some possible implementations, both the first shaft and the second shaft include a connector and a cylinder, the connector being fixed to the base, the cylinder being sleeved on the connector, and being able to rotate relative to the connector.

[0014] In some possible implementations, the first wheel and the second wheel are arranged at intervals from bottom to top in the vertical direction on the base, and the third wheel and the fourth wheel are arranged at intervals from bottom to top in the vertical direction on the base.

[0015] In some possible implementations, the first wheel, the second wheel, the third wheel, and the fourth wheel are all connected to the base via a pivot. In the first wheel and the second wheel, the pivot of at least one of them is adjustable in position along the vertical direction and is also ...

[0016] In some possible implementations, the base is provided with two sets of elongated holes, each set including two elongated holes disposed on opposite side walls of the base and extending vertically. The two sets of elongated holes correspond to the second wheel and the fourth wheel, respectively. The two ends of the shaft of the second wheel pass through the corresponding two elongated holes, and both ends of the shaft are fixed to the base by a first nut. The two ends of the shaft of the fourth wheel pass through the corresponding two elongated holes, and both ends of the shaft are fixed to the base by a second nut.

The machine base is provided with an internally threaded hole communicating with the elongated hole. The internally threaded hole extends vertically.

[0018] In some possible implementations, the base includes a top plate, a bottom plate, and two side plates, the two side plates being spaced apart and detachably connected to the bottom plate, and the two ends of the top plate being detachably connected to the two side plates respectively.

[0019] In some possible implementations, the base is provided with an observation hole.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a cable bow stranding machine guide plate pressing device, including a base, a forming assembly, a first pressing mechanism, and a second pressing mechanism. Through the combined action of a first shaft, a first cylindrical surface, a second cylindrical surface, a third cylindrical surface, a fourth cylindrical surface, and a second shaft, the overall curvature of the guide plate is pressed out. The convex arc structure of the guide plate is pressed out through the cooperation of annular convex and concave arc surfaces. A driving assembly provides driving force to drive the first wheel to rotate, simultaneously pressing the guide plate and pulling it from the feed port to the discharge port for traction, or performing short-distance reciprocating movement of the guide plate to ensure the forming effect. By setting grooves on both the third and fourth wheels, the formed convex arc structure is avoided, and the overall curvature of the guide plate is prevented from being affected when the guide plate is removed from the second pressing mechanism. Therefore, this utility model can realize the manufacturing of guide plates. Compared with more complex stamping equipment, the structure is simpler, the cost of the device is lower, and the manufacturing operation of the guide plate is simple. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0040] like Figure 1 As shown, in this embodiment, the guide piece 100 is sequentially divided into a first arc segment 101, a horizontal segment 102, and a second arc segment 103 along its length. The guide piece 100 also has a convex arc structure 104, which covers the entire guide piece 100 along its extension direction. The guide piece 100 is made of manganese steel, which is not easily bent. Figures 2 to 6 As shown, this utility model provides a cable bow stranding guide plate rolling device, including a base 1, a shaping assembly 2, a first rolling mechanism 3, and a second rolling mechanism 4. The base 1 is provided with a feed inlet 11 and a discharge outlet 12. The shaping assembly 2 includes a first shaft 21 and a second shaft 22. The first shaft 21 is located at the feed inlet 11, and the second shaft 22 is located at the discharge outlet 12. The first rolling mechanism 3 is located inside the base 1 and on the side of the first shaft 21 away from the feed inlet 11. The first rolling mechanism 3 includes a first wheel 31, a second wheel 32, and a drive assembly. The first wheel 31 and the second wheel 32 are vertically spaced on the base 1 and can both rotate relative to the base 1. The drive assembly is used to drive the first wheel 31 to rotate. The first wheel 31 is provided with a first cylindrical surface 311 and an annular convex arc surface 312. Specifically, the two first cylindrical surfaces... 311 is located on both sides of the annular convex arc surface 312. The second wheel 32 is provided with a second cylindrical surface 321 and an annular concave arc surface 322. Specifically, the two second cylindrical surfaces 321 are located on both sides of the annular concave arc surface 322. The second cylindrical surface 321 cooperates with the first cylindrical surface 311, and the annular concave arc surface 322 cooperates with the annular convex arc surface 312. The second rolling mechanism 4 is located in the machine base 1 and between the first rolling mechanism 3 and the second shaft 22. The second rolling mechanism 4 includes a third wheel 41 and a fourth wheel 42. The third wheel 41 and the fourth wheel 42 are arranged vertically at intervals on the machine base 1 and can rotate relative to the machine base 1. The third wheel 41 is provided with a third cylindrical surface 411, and the fourth wheel 42 is provided with a fourth cylindrical surface 421 that cooperates with the third cylindrical surface 411. Both the third wheel 41 and the fourth wheel 42 are provided with grooves 10. Specifically, two third cylindrical surfaces 411 are located on both sides of the groove 10 of the third wheel 41, and two fourth cylindrical surfaces 421 are located on both sides of the groove 10 of the fourth wheel 42.

[0041] For example, when processing the guide piece 100, the blank sheet is passed through the upper end of the first shaft 21 and extends to the gap between the first wheel 31 and the second wheel 32. The first wheel 31 is driven to rotate by the drive assembly, which in turn drives the first wheel 31 and the second wheel 32 to rotate, thereby pulling the blank sheet towards the discharge port 12, so that the blank sheet extends into the gap between the third wheel 41 and the fourth wheel 42 and extends from the upper end of the second shaft 22. Through the short-distance reciprocating movement of the drive assembly, the blank sheet is reciprocated and pressed to form the overall curvature of the guide piece 100. In this process, the convex arc structure 104 of the guide piece 100 is pressed out by the cooperation of the annular convex arc surface 312 and the annular concave arc surface 322. When the blank sheet is pressed between the third wheel 41 and the fourth wheel 42, the groove 10 of the fourth wheel 42 can prevent the formed convex arc structure 104 from being pressed. After processing, when the guide sheet 100 is taken out from the second rolling mechanism 4, the groove 10 of the third wheel 41 and the fourth wheel 42 can prevent the curvature of the horizontal section 102 and the second arc section 103 from being affected, thereby preventing the overall curvature of the guide sheet 100 from being affected.

[0042] Through the combined action of the first shaft 21, the first cylindrical surface 311, the second cylindrical surface 321, the third cylindrical surface 411, the fourth cylindrical surface 421, and the second shaft 22, the overall curvature of the guide piece 100 is pressed out. The convex arc structure 104 of the guide piece 100 is pressed out through the cooperation of the annular convex arc surface 312 and the annular concave arc surface 322. The driving assembly provides driving force, driving the first wheel 31 to rotate. While pressing the guide piece 100, it also pulls the guide piece 100 from the feed port 11 to the discharge port 12 to provide traction, or performs short-distance reciprocating movement of the guide piece 100 to ensure the forming effect of the guide piece 100. By providing grooves 10 on both the third wheel 41 and the fourth wheel 42, the formed convex arc structure 104 is avoided, and the overall curvature of the guide piece 100 is prevented from being affected when the guide piece 100 is removed from the second rolling mechanism 4. Therefore, this utility model can realize the manufacturing of cable pantograph guide plate 100. Compared with relatively complex stamping equipment, the structure is simple, the cost of the device is low, and the manufacturing operation of guide plate 100 is simple.

[0043] Optionally, in this embodiment, the base 1 includes a top plate 15, a bottom plate 16, and two side plates 17. The two side plates 17 are spaced apart and detachably connected to the bottom plate 16, and both ends of the top plate 15 are detachably connected to the two side plates 17 respectively. This configuration simplifies the structure of the base 1, facilitates assembly and disassembly, and minimizes its space occupation. Specifically, screws are attached to both the top plate 15 and the bottom plate 16. The screws on the top plate 15 pass through the top plate 15 and are threadedly connected to threaded holes at the top of the side plates 17. The screws on the bottom plate 16 pass through the bottom plate 16 and are threadedly connected to threaded holes at the bottom of the side plates 17. Optionally, the base 1 is made of 45# steel.

[0044] Optionally, in this embodiment, the machine base 1 is provided with an observation hole 18. This arrangement facilitates observation of the running status of the billet within the machine base 1.

[0045] Optionally, in this embodiment, in the first wheel 31 and the second wheel 32, one of them has a first limiting protrusion 323 on both opposite sides along the axial direction, and the other has a first clearance groove 313 on both opposite sides along the axial direction, with the first clearance groove 313 facing the first limiting protrusion 323. In the third wheel 41 and the fourth wheel 42, one of them has a second limiting protrusion 422 on both opposite sides along the axial direction, and the other has a second clearance groove 412 on both opposite sides along the axial direction, with the second clearance groove 412 facing the second limiting protrusion 422. By setting the first limiting protrusion 323 and the second limiting protrusion 422, the movement of the billet sheet is guided, ensuring the accuracy of the billet sheet's movement direction. By setting the first clearance groove 313 and the second clearance groove 412, the first limiting protrusion 323 and the second limiting protrusion 422 are avoided.

[0046] Optionally, in this embodiment, as Figure 2 As shown, the first wheel 31 is connected to the base 1 via a rotating shaft 20. The rotating shaft 20 passes through the side wall of the base 1 and extends out of the base 1. The drive assembly includes a sleeve 33 and an electric wrench. The sleeve 33 is detachably connected to the extended end of the rotating shaft 20. The electric wrench is inserted into the sleeve 33 and is used to drive the sleeve 33 to rotate, thereby driving the rotating shaft 20 to rotate, and in turn driving the first wheel 31 to rotate. With this configuration, the rotation of the first wheel 31 can be achieved by manually operating the electric wrench. The drive assembly has a simple structure with no complex transmission components, and the operator does not need to contact the high-speed moving mechanism, which can reduce the safety risks for the operator during operation. Specifically, the sleeve 33 is a hexagonal prism structure with a through hole. Optionally, the sleeve 33 is fixed to the rotating shaft 20 corresponding to the first wheel 31 by screws. In other embodiments, the drive assembly is a motor, which is fixed to the base 1 and drives the rotating shaft 20 corresponding to the first wheel 31 to rotate.

[0047] Optionally, in this embodiment, both the first shaft 21 and the second shaft 22 include a connector 30 and a cylinder 40. The connector 30 is fixed to the machine base 1, and the cylinder 40 is sleeved on the connector 30 and can rotate relative to the connector 30. The rotation of the cylinder 40 relative to the connector 30 facilitates the movement of the blank sheet. In this embodiment, the connector 30 is a bolt, which passes through one side plate 17, extends into the gap between the two side plates 17, and is threadedly connected to the other side plate 17. This arrangement simplifies the structure of the connector 30.

[0048] Optionally, in this embodiment, the first wheel 31 and the second wheel 32 are arranged alternately from bottom to top vertically on the base 1, and the third wheel 41 and the fourth wheel 42 are arranged alternately from bottom to top vertically on the base 1. With this arrangement, the first wheel 31 is located at the lower end of the base 1. When the driving component is an electric wrench, it facilitates the operator to use the electric wrench to rotate the first wheel 31; when the driving component is a motor, it facilitates the installation of the motor. In other embodiments, the second wheel 32 and the first wheel 31 are arranged alternately from bottom to top vertically on the base 1, and the fourth wheel 42 and the third wheel 41 are arranged alternately from bottom to top vertically on the base 1.

[0049] In addition, such as Figure 6 As shown, the first wheel 31, the second wheel 32, the third wheel 41, and the fourth wheel 42 are all connected to the machine base 1 via a rotating shaft 20. The first wheel 31 is connected to the rotating shaft 20 via a key, and the rotating shaft 20 is connected to the machine base 1 via a bearing 70. The second wheel 32, the third wheel 41, and the fourth wheel 42 are all connected to their corresponding rotating shafts 20 via bearings 70, and the corresponding rotating shafts 20 are all fixed to the machine base 1. Specifically, the bearings 70 corresponding to the first wheel 31, the second wheel 32, the third wheel 41, and the fourth wheel 42 are all self-lubricating bearings, which have high reliability and reduce maintenance costs. A retaining ring 80 and a brass washer 90 are fitted on the rotating shafts 20 corresponding to the second wheel 32, the third wheel 41, and the fourth wheel 42 to facilitate determining the axial position of the second wheel 32, the third wheel 41, and the fourth wheel 42 on their respective rotating shafts 20.

[0050] Optionally, in the first wheel 31 and the second wheel 32, the shaft 20 of at least one of them is adjustable in the vertical direction and mounted on the machine base 1; in the third wheel 41 and the fourth wheel 42, the shaft 20 of at least one of them is adjustable in the vertical direction and mounted on the machine base 1. In this embodiment, the shaft 20 of the second wheel 32 is adjustable in the vertical direction and mounted on the machine base 1, and the shaft 20 of the fourth wheel 42 is also adjustable in the vertical direction and mounted on the machine base 1. This arrangement facilitates adjustment of the clamping force on the blank sheet to meet actual needs.

[0051] Optionally, such as Figure 2As shown, the machine base 1 has two sets of elongated holes, each set including two elongated holes 13. The two elongated holes 13 are located on opposite side walls of the machine base 1 and extend vertically. The two sets of elongated holes correspond to the second wheel 32 and the fourth wheel 42, respectively. The two ends of the rotating shaft 20 of the second wheel 32 pass through the corresponding two elongated holes 13, and both ends of the rotating shaft 20 are fixed to the machine base 1 by a first nut 50. Similarly, the two ends of the rotating shaft 20 of the fourth wheel 42 pass through the corresponding two elongated holes 13, and both ends of the rotating shaft 20 are fixed to the machine base 1 by a second nut 60. By adjusting the position of the rotating shaft 20 in the elongated holes 13, the relative positions between the first wheel 31 and the second wheel 32, as well as between the third wheel 41 and the fourth wheel 42, are changed, thereby adjusting the pressing force on the blank sheet. The structure is simple and the adjustment is convenient. Specifically, a washer is fitted onto the rotating shaft 20 corresponding to the second wheel 32 and the fourth wheel 42, and the first nut 50 or the second nut 60 presses the washer against the machine base 1. Specifically, the elongated hole 13 is a waist-shaped hole.

[0052] Furthermore, such as Figure 2 and Figure 6 As shown, the cable bow winch guide plate pressing device also includes adjusting bolts 5, which are correspondingly arranged with elongated holes 13. The machine base 1 is provided with an internally threaded hole 14 communicating with the elongated hole 13. The internally threaded hole 14 extends vertically, and the adjusting bolt 5 is threadedly connected to the internally threaded hole 14 and extends into the elongated hole 13 to abut against the corresponding rotating shaft 20. During adjustment, the first nut 50 or the second nut 60 can be loosened first, without changing the position of the rotating shaft 20. Then, by turning the adjusting bolt 5, the rotating shaft 20 can be moved to adjust its position. After reaching the set position, the first nut 50 or the second nut 60 is tightened. This arrangement makes the adjustment position of the rotating shaft 20 more precise.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
