Description

Technical Field

[0001] The invention relates to the technical field of cable bender, in particular to a cable bender. Background Art

[0002] At present, in the construction and maintenance of power cables, due to factors such as process requirements or restrictions on special construction sites, it is often necessary to use a manual bender to bend the cable to change the path to meet the installation requirements and achieve effective connection with power supply and use equipment such as overhead lines, switch cabinets and metering facilities. In this way, the operator does not need to estimate the bending length and curve curvature in advance, and can directly put the manual bender on the cable to perform the bending operation after the bending is completed.

[0003] In the prior art, the name disclosed in the application number: CN201510781856.1 is: a wire bending device, which includes a first pressing plate and a second pressing plate that are hingedly arranged; a main shaft bending wheel is provided on the hinge shaft of the first pressing plate and the second pressing plate; a wire pressing wheel is provided on each of the two opposite surfaces of the first pressing plate and the second pressing plate; at least one pressing plate has a slide groove along its length direction, a slider that slides with the slide groove is provided in the slide groove, and the wire pressing wheel on the pressing plate with the slide groove is provided on the slider, and the slider is connected to one end of a push rod inserted in the slide groove and extending outside the pressing plate; a ruler extending toward the other pressing plate is provided at the tail end of one of the pressing plates, and a first positioning hole is provided at the position corresponding to the standard bending angle on the ruler, and a second positioning hole is provided on the other pressing plate at the same time. The present invention can effectively prevent the steel strand from bouncing off due to careless operation during the wire bending process, ensure the personal safety of the operator, and the completed bending structure is standardized and consistent, and accurately matches the shape of the tongue plate.

[0004] However, in the prior art, for example, the bender mentioned in the application number: CN201510781856.1, during actual use, although the two pressure plates can be fixed by pins or bolts, so that even if the hand is released, the pull wire, i.e., the steel strand, will not bounce off and injure people, but the bent steel strand, i.e., the cable, is simply put on the first crimping wheel and the second crimping wheel, and lacks a good blocking and limiting cable structure, which makes it easy for the bender to cause the bent cable to detach from the bender due to accidental movement, and the bent cable detached from the bender may rebound and injure the operator, which may affect the safety of the operator when bending the cable, and therefore, it needs to be improved.

[0020] 2. By setting up a pushing component and rotating the second rotating disk, the second threaded rod drives the second empty box block to move along the side of the second fixed plate through the first fixed plate, so that the rounded baffle squeezes the rounded cable onto the bending rod to continue bending, thereby increasing the range of cable bending angles of the device and thereby improving the cable bending effect of the device.

[0021] 3. By setting an adjustment component and rotating the moving bolt, the moving bolt drives the rounded baffle plate to move toward the fixed baffle rod through the convex sleeve block, so that the distance between the rounded baffle plate and the fixed baffle rod gradually changes until it stops at a suitable distance, so that cables with different outer diameters can be placed between the fixed baffle rod and the rounded baffle plate, and then the bending rod is driven by the first empty box block to bend the cable, thereby increasing the range of the outer diameter of the cable that can be bent by the equipment.

[0022] 4. By setting a fixed baffle, when the first empty box block is located in front of the second empty box block as a whole, the operator rotates the first rotating disk, which will cause the first rotating disk to drive the first empty box block as a whole to move backward through the first threaded rod, and the moving rod moves along the inner wall of the connecting plate, so that the first empty box block squeezes the cable line through the bending rod and bends it backward along the fixed baffle, thereby achieving the purpose of bending the cable line backward and increasing the range of the cable bending direction of the equipment.

[0035] Embodiment 1, according to Figures 1 to 10As shown, a cable bender comprises a first empty box block 1, a first threaded rod 2 is rotatably installed inside the first empty box block 1, a connecting plate 5 is threadedly sleeved on the other end of the first threaded rod 2, a first rotating disk 3 is fixed to one end of the first threaded rod 2, a moving rod 6 fixed to the first empty box block 1 is movably sleeved inside the upper end of the connecting plate 5, a bending rod 7 is fixed on the top of the first empty box block 1, a pushing component 8 located on the right side of the first threaded rod 2 is installed on the connecting plate 5, a second empty box block 9 at the same position as the top surface of the first empty box block 1 is connected to the other end of the pushing component 8, an adjusting component 10 is installed on the upper end of the second empty box block 9, a rounded baffle 11 in contact with the top of the second empty box block 9 is connected to the adjusting component 10, a connecting round rod 13 is movably sleeved inside the rear end of the second empty box block 9, and a rotating block that blocks the cable is fixed to the upper end of the connecting round rod 13 14. A square groove round block 15 is fixed to the lower end of the connecting round rod 13, and a rotating square block 16 is rotatably installed inside the lower end of the first empty box block 1. The other end of the rotating square block 16 passes through the square groove round block 15. By rotating the first rotating disk 3, the first threaded rod 2 will drive the first empty box block 1 to move as a whole, and the moving rod 6 will move along the inner wall of the connecting plate 5, so that the first empty box block 1 drives the square groove round block 15 to rotate through the rotating square block 16, and then the square groove round block 15 drives the rotating stopper 14 to rotate through the connecting round rod 13, so that the rotating stopper 14 blocks and limits the cable between the rounded baffle 11 and the connecting round rod 13, and at the same time, the bending rod 7 will squeeze the cable to bend forward along the rounded corner of the rounded baffle 11. Such a design can prevent the cable from escaping from the bender and injuring the operator when bending.

[0036] A blocking block 17 is fixed to the upper end of the bending rod 7. The outer diameter of the blocking block 17 is larger than the outer diameter of the bending rod 7. Through the design of the outer diameters of the blocking block 17 and the bending rod 7, the blocking block 17 can block the cable bent by the bending rod 7 from moving upward, thereby achieving the purpose of better limiting the cable.

[0037] The top surface position of the second empty box block 9 is the same as the top surface position of the connecting plate 5. The top surfaces of the second empty box block 9 and the connecting plate 5 are both smooth. Through the design of the second empty box block 9 and the connecting plate 5, the cable bent by the bending rod 7 will not be blocked by the connecting plate 5, thereby making the device bend the cable over a longer distance, thereby improving the purpose of the device bending the cable length.

[0038] A handle 4 is fixed on the front side of the connecting plate 5 , and the outer surface of the handle 4 is rough. Through the design of the handle 4 , the operator can better pick up the connecting plate 5 as a whole to perform bending operations on the cable.

[0039] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0040] Embodiment 2, as Figures 1 to 8 As shown, the pushing assembly 8 includes a first fixed plate 801 fixed to the side of the second empty box block 9, a second threaded rod 802 is rotatably installed inside the first fixed plate 801, the other end of the second threaded rod 802 is fixedly connected to a second rotating disk 803, and a second fixed plate 804 located between the first fixed plate 801 and the second rotating disk 803 is threadedly sleeved on the second rotating disk 803, one end of the second fixed plate 804 contacts the side of the second empty box block 9, and the other end of the second fixed plate 804 is fixedly connected to the side of the connecting plate 5, and the second rotating disk 803 is rotated so that the second threaded rod 802 drives the second empty box block 9 to move along the side of the second fixed plate 804 through the first fixed plate 801. When the first empty box block 1 is bent with a straight rounded corner by the bending rod 7, the second empty box block 9 can be moved as a whole at this time, so that the rounded corner baffle 11 pushes the cable to continue to bend on the bending rod 7, thereby achieving the purpose of continuing to bend the cable after the straight rounded corner bending.

[0041] The second fixed plate 804 is internally movably sleeved with a first limiting rod 805, one end of which is fixedly connected to the first fixed plate 801, and the other end of which extends to the outside of the second fixed plate 804. Through the design of the first limiting rod 805, the second fixed plate 804 can better reinforce and support the first fixed plate 801 as a whole through the first limiting rod 805, thereby achieving the purpose of reinforcing and supporting the first fixed plate 801 as a whole.

[0042] Based on the second embodiment, the solution in the second embodiment is further detailed in combination with the following specific working method, as described below for details.

[0043] Embodiment three, as Fig. 9 As shown, the adjustment component 10 includes a fixed mounting frame 1001 fixed to the front side of the second empty box block 9, the fixed mounting frame 1001 is located above the pushing component 8, the internal thread of the fixed mounting frame 1001 is sleeved with a moving bolt 1002, one end of the moving bolt 1002 is located outside the fixed mounting frame 1001, and the other end of the moving bolt 1002 is fixed to a convex sleeve block 1003 that is limitedly sleeved inside the rounded baffle 11. By rotating the moving bolt 1002, the moving bolt 1002 drives the rounded baffle 11 to move along the top surface of the second empty box block 9 through the convex sleeve block 1003, thereby adjusting the distance between the rounded baffle 11 and the connecting round rod 13, so that the rounded baffle 11 can limit cables with different outer diameters through the connecting round rod 13, and the range of the outer diameter of the cable bent by the device is increased.

[0044] The interior of both ends of the fixed mounting frame 1001 is movably sleeved with a second limit rod 1004, one end of the second limit rod 1004 is located outside the fixed mounting frame 1001, and the other end of the second limit rod 1004 is fixedly connected to the rounded corner baffle 11. Through the design of the two second limit rods 1004, the two second limit rods 1004 reinforce the rounded corner baffle 11 through the fixed mounting frame 1001, so that the rounded corner baffle 11 can better resist the extrusion force when the cable is bent.

[0045] Based on the third embodiment, the scheme in the third embodiment is further detailed in combination with the following specific working method, as described below for details.

[0046] Embodiment 4, as Figure 1 As shown, a fixed baffle 12 is fixed to the top of the second empty box block 9, and the fixed baffle 12 is located at the left end behind the second empty box block 9. Through the design of the fixed baffle 12, when the first empty box block 1 drives the bending rod 7 to move to the front of the cable, the operator rotates the first rotating disk 3 at this time, so that the first rotating disk 3 will drive the first empty box block 1 to move backward as a whole through the first threaded rod 2, and then the first empty box block 1 squeezes the cable through the bending rod 7 and bends it backward along the fixed baffle 12, thereby increasing the range of the cable bending direction of the device.

[0047] When used specifically, the present invention is used as a cable bender. First, the operator rotates the moving bolt 1002, so that the moving bolt 1002 drives the convex sleeve block 1003 to rotate along the inner wall of the rounded baffle 11, and then the moving bolt 1002 drives the rounded baffle 11 to move toward the connecting round rod 13 through the convex sleeve block 1003, and the second limiting rod 1004 moves along the inner wall of the fixed mounting frame 1001 to limit the rounded baffle 11, so that the distance between the rounded baffle 11 and the fixed baffle rod 12 gradually changes until it stops at a suitable distance, so that cables with different outer diameters can be placed between the connecting round rod 13 and the rounded baffle 11, and then the bending rod 7 is driven by the first empty box block 1 to bend the cable, thereby increasing the range of the outer diameter of the cable bent by the device.

[0048] Then the operator holds the connecting plate 5 as a whole by the handle 4, and places the cable to be bent between the rounded baffle 11 and the connecting round rod 13 on the second empty box block 9. Then the operator rotates the first rotating disk 3, so that the first threaded rod 2 drives the first empty box block 1 as a whole to move toward the connecting plate 5, and the moving rod 6 moves along the inner wall of the connecting plate 5 to limit the first empty box block 1, so that the first empty box block 1 is squeezed by the bending rod 7 to bend forward along the rounded corner of the rounded baffle 11. At this time, since the outer diameter of the blocking round block 17 is larger than the outer diameter of the bending rod 7, the blocking round block 17 can better block the bent cable from moving upward The first empty box block 1 will rotate counterclockwise through the rotating square block 16, and the square groove round block 15 will rotate counterclockwise through the connecting round rod 13, so that the rotating block 14 will rotate above the cable, so that the rotating block 14 will limit the cable on the second empty box block 9 through the rounded baffle 11 and the connecting round rod 13, so as to prevent the cable from escaping from the bender and injuring the operator when bending, so that the bender will not accidentally move when bending the cable, causing the cable to detach from the bender and injure the operator, thereby ensuring the safety of the operator when bending the cable.

[0049] When the cable is bent with a straight round corner and the first empty box block 1 is located in front of the first fixed plate 801, the operator rotates the second rotating disk 803, so that the second threaded rod 802 drives the second empty box block 9 to move along the side of the second fixed plate 804 through the first fixed plate 801, and then the rounded baffle 11 squeezes the cable after the straight round corner bend onto the bending rod 7 to continue bending, thereby achieving the purpose of increasing the angle range of the cable bending device, thereby improving the cable bending effect of the device.

[0050] When the cable is bent and shaped, the operator reverses the second rotating disk 803, so that the second threaded rod 802 drives the second empty box block 9 to move as a whole to the right side of the first empty box block 1 through the first fixed plate 801, and then reverses the first rotating disk 3, so that the first threaded rod 2 drives the first empty box block 1 to move backward and reset, until the first empty box block 1 drives the bending rod 7 to separate from the outer surface of the bent cable and stops. During the movement and reset of the first empty box block 1, the rotating square block 16 will drive the square groove round block 15 to rotate clockwise, and then the square groove round block 15 drives the rotating stopper 14 to separate from the top of the cable through the connecting round rod 13. Then the operator can hold the connecting plate 5 with the handle 4 to separate from the outer surface of the bent cable as a whole, thereby achieving the purpose of bending the cable nearby and facilitating separation.

[0051] When the cable needs to be bent backward, the operator rotates the first rotating disk 3 forward, so that the first rotating disk 3 will drive the first empty box block 1 to move backward as a whole through the first threaded rod 2, until the first empty box block 1 is located in front of the second empty box block 9 and stops, and then the operator puts the cable to be bent between the fixed baffle 12 and the rounded baffle 11 on the second empty box block 9, and then the operator reverses the first rotating disk 3, so that the first threaded rod 2 will drive the first empty box block 1 to move backward as a whole, and the moving rod 6 moves along the inner wall of the connecting plate 5, so that the first empty box block 1 squeezes the cable through the bending rod 7 and bends it backward along the fixed baffle 12, thereby achieving the purpose of increasing the direction range of the cable bending device.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
