DETAILED DESCRIPTION

[0028] The wire bending device provided by the utility model is explained and illustrated in detail below in conjunction with the drawings of the specification.

[0029] This embodiment specifically discloses a wire bending device, such as Figure 1-4 As shown, it includes a support seat 1, a first clamping mechanism 2, a second clamping mechanism 3 and a winding column 4. The support seat 1 is used to fix and support the first clamping mechanism 2, the second clamping mechanism 3 and the winding column 4, and provide a bending operation platform. In this embodiment, the support seat 1 includes a support plate 11 and a support leg 12 fixed below the support plate 11. The number of the support legs 12 is two, which are relatively arranged below the support plate 11, and the two support legs 12 are respectively close to two edges of the support plate 11. A through hole can be opened at the bottom of the support leg 12, and the support seat is fixed to the workbench on site by screws passing through the through hole.

[0030] The first clamping mechanism 2 and the second clamping mechanism 3 are both arranged on the support seat 1. The first clamping mechanism 2 and the second clamping mechanism 3 are both arranged on the top surface of the support plate 11. The first clamping mechanism 2 is fixedly connected to the support seat 1. The first clamping mechanism 2 and the second clamping mechanism 3 are arranged relatively. In the initial state, the first clamping mechanism 2 and the second clamping mechanism 3 are on the same straight line. The winding post 4 is arranged at the end of the second clamping mechanism 3 close to the first clamping mechanism 2. The winding post 4 has a variety of specifications. The outer diameters of the winding parts 41 of the winding posts 4 of different specifications are different. The winding post 4 is detachably connected to the support seat 1. The winding post 4 is used to wind the wire 9 and then bend the wire 9. Different bending radii can be achieved by selecting winding parts 41 with different outer diameters. The winding post 4 can be replaced by the detachable connection between the winding post 4 and the support seat 1, thereby improving the flexibility of the performance detection of the wire 9 and adjusting the bending radius according to the actual performance test needs, thereby improving the accuracy of the performance detection of the wire 9. The first clamping mechanism 2 is used to clamp one section of the wire 9, and the second clamping mechanism 3 is used to clamp the other section of the wire 9. In the initial state, the first clamping mechanism 2 and the second clamping mechanism 3 are on the same straight line. After being clamped by the first clamping mechanism 2 and the second clamping mechanism 3, the wire 9 is in a straight line, and the wire 9 is tightly attached to the side of the winding portion 41. The wire section clamped by the first clamping mechanism 2 serves as a fixed section, and the wire section clamped by the second clamping mechanism 3 serves as a movable section. The end of the second clamping mechanism 3 close to the first clamping mechanism 2 is rotatably connected to the winding portion 41 and drives the clamped wire section to rotate around the winding portion 41 to wind the wire 9 around the winding portion 41, thereby bending the wire 9.

[0031] The winding post 4 includes a winding portion 41 and a wire pressing portion 42 on the top of the winding portion 41. The wire pressing portion 42 and the winding portion 41 can be integrally formed or connected by screws. The outer diameter of the wire pressing portion 42 is larger than the outer diameter of the winding portion 41. The winding post 4 is vertically slidably connected to the support seat 1. A sliding drive mechanism 5 is fixed on the support seat 1. The winding post 4 slides up and down relative to the support seat 1 under the drive of the sliding drive mechanism 5. In this embodiment, a through hole is provided on the support plate 11 for the winding portion 41 to pass through. The bottom of the winding portion 41 can be located below the support plate 11 after passing through the through hole. The winding portion 41 slides up and down along the through hole, and the wire pressing portion 42 is always located above the support plate 11. The wire pressing portion 42 is used to press on the wire 9 when bending the wire 9 to prevent the bent portion of the wire 9 from arching and warping during the bending process. The winding post 4 slides up and down relative to the support seat 1 to adjust the distance between the wire pressing portion 42 and the support plate 11 to adapt to wires 9 of different thicknesses (ie, heights), ensuring that the wire pressing portion 42 can press on the wires 9 .

[0032] like Figure 1 and 2 As shown, the winding column 4 is connected to the sliding drive mechanism 5 through the adapter mechanism 6. In this embodiment, the sliding drive mechanism 5 is fixed below the support plate 11 and between the two support legs 12. The sliding drive mechanism 5 is fixedly connected to the support plate 11 through the second fixed plate 14. The second fixed plate 14 is L-shaped. The top of the vertical plate of the second fixed plate 14 is fixedly connected to the support plate 11, and the horizontal plate of the second fixed plate 14 is fixedly connected to the sliding drive mechanism 5. Preferably, the sliding drive mechanism 5 is an electric telescopic rod, a pneumatic cylinder or a hydraulic cylinder. The fixed part of the sliding drive mechanism 5 is fixedly connected to the horizontal plate of the second fixed plate 14, and the telescopic part is located above the horizontal plate of the second fixed plate 14 as a driving end. The switching mechanism 6 includes a movable plate 61, a first rotating shaft 62, a second rotating shaft 63 and a third rotating shaft 64. The switching mechanism 6 is also arranged below the support plate 11. The winding portion 41 penetrates the support plate 11 and its bottom is located below the support plate 11. The third rotating shaft 64 is detachably connected to the winding post 4, that is, the third rotating shaft 64 is detachably connected to the bottom of the winding portion 41, and the third rotating shaft 64 is perpendicular to the central axis of the winding post 4. Figure 2As shown, the third rotating shaft 64 is detachably connected to the winding part 41 through the second adapter block 67, and the third rotating shaft 64 is fixed on the second adapter block 67. The top of the second adapter block 67 is provided with an internal thread, and the bottom of the winding part 41 is provided with an external thread. The winding part 41 is threadedly connected to the second adapter block 67 to realize the detachable connection between the winding part 41 and the third rotating shaft 64; the first rotating shaft 62 and the second rotating shaft 63 are arranged parallel to the third rotating shaft 64, and the first rotating shaft 62, the second rotating shaft 63 and the third rotating shaft 64 are all arranged horizontally, and the first rotating shaft 62 is fixedly connected to the driving end of the sliding driving mechanism 5, and the first rotating shaft 62 is fixedly connected to the driving end of the sliding driving mechanism 5 through the first adapter block 66, and the first adapter block 66 is connected to the sliding driving mechanism 5. The driving end of the movable mechanism 5 is threadedly connected, and the first rotating shaft 62 is fixed on the first adapter block 66; the second rotating shaft 63 is fixedly connected to the support seat 1, and the second rotating shaft 63 is fixedly connected to the support seat 1 through the fixed plate 65, and the top of the fixed plate 65 is fixedly connected to the bottom surface of the support seat 1, and the second rotating shaft 63 is fixed on the support plate 11; one end of the movable plate 61 is sleeved on the first rotating shaft 62 and rotates around the first rotating shaft 62, the middle part of the movable plate 61 is sleeved on the second rotating shaft 63 and rotates around the second rotating shaft 63, and the other end of the movable plate 61 is provided with a strip through hole 611 along the length direction of the movable plate 61, and the movable plate 61 is sleeved on the third rotating shaft 64 through the strip through hole 611 and can rotate around the third rotating shaft 64. Figure 2 As shown, when the driving end of the sliding driving mechanism 5 moves upward, the left end of the movable plate 61 moves upward and rotates around the first rotating shaft 62, the middle part of the movable plate 61 rotates around the second rotating shaft 63, and the right end of the movable plate 61 moves downward. While the right end of the movable plate 61 rotates around the third rotating shaft 64, the third rotating shaft 64 is driven to move downward along the strip-shaped through hole 611, thereby driving the winding part 41 to move downward; similarly, when the driving end of the sliding driving mechanism 5 moves downward, the winding part 41 moves upward through the switching action of the switching mechanism 6. The combination of the movable plate 61, the first rotating shaft 62, the second rotating shaft 63 and the third rotating shaft 64 uses the lever principle to realize the transmission of force, and the setting of the fixed plate 65 provides space for the movable plate 61 to rotate in the vertical plane.

[0033] In another optional embodiment, the driving end of the sliding driving mechanism 5 can also be directly fixedly connected to the bottom of the winding part 41 or the top of the wire pressing part 41, as long as it can drive the winding column 4 to slide up and down.

[0034] like Figure 1 , 2As shown in Figure 3, the first clamping mechanism 2 includes a pressing block 21, a driving mechanism 22 and a plurality of wire fixing blocks 23. The wire fixing blocks 23 are provided with wire slots 231. The wire slots 231 on the plurality of wire fixing blocks 23 have different specifications to match wires 9 of different specifications. The wire fixing blocks 23 are detachably connected to the support seat 1. Each wire fixing block 23 is provided with only one wire slot 231. The wire slots 231 on the wire fixing blocks 23 have different specifications. The specifications of the wire slots 231 refer to the width and height of the wire slots 231. The wire fixing blocks 23 are replaced by the detachable connection between the wire fixing blocks 23 and the support seat 1, and then the wire slots 231 of different specifications are replaced to match the specifications of the wires 9. In this embodiment, the specifications of the wires 9 refer to the cross-sectional dimensions of the wires 9. If the cross-sectional dimensions of the wires 9 are circular, the specifications refer to the cross-sectional radius or diameter of the wires 9; if the cross-sectional dimensions of the wires 9 are square or rectangular (i.e., the wires 9 are flat wires), the specifications refer to the width and height of the cross-sectional dimensions of the wires 9.

[0035] The height of the wire slot 231 is less than or equal to the height of the wire 9 of the corresponding specification. The pressing block 21 is arranged above the wire slot 231 and moves up and down by the drive of the driving mechanism 22. The height of the wire slot 231 is set so that the top surface of the wire 9 is flush with the wire slot 231 or protrudes from the wire slot 231, ensuring that the pressing block 21 can press on the wire 9 and clamp the wire 9 between the pressing block 21 and the bottom of the wire slot 231 in the vertical direction. The shape of the wire slot 231 matches the shape of the wire 9. When the cross section of the wire 9 is circular, the wire slot 231 is an arc-shaped slot; when the cross section of the wire 9 is square or rectangular, the wire slot 231 is a U-shaped slot. The wire slot 231 cooperates with the pressing block 21 to fix the wire 9 in all directions, and fixes the position of the clamped wire segment so that it will not move.

[0036] Optionally, the driving mechanism 22 is an electric telescopic rod, a linear cylinder or a hydraulic cylinder. The driving mechanism 22 is fixedly connected to the support seat 1 through a first fixed plate 13. The first fixed plate 13 is vertically fixed on the support plate 11. The fixed part of the driving mechanism 22 is fixedly connected to the first fixed plate 13. The driving end of the driving mechanism 22 is below the fixed part, and the pressure block 21 is below the driving mechanism 22. The driving end of the driving mechanism 22 is fixedly connected to the pressure block 21 by screws, thereby driving the pressure block 21 to move up and down.

[0037] Optionally, the pressing block 21 is made of Teflon material, which has a certain plasticity and can prevent the wire 9 from being crushed to a certain extent.

[0038] Optional, such as Figure 1-3As shown, the wire fixing block 23 is detachably connected to the support base 1 through a fixing base 24, the fixing base 24 is fixed on the support base 1, and the fixing base 24 can be fixed on the top surface of the support plate 11 by screws. The top surface of the fixing base 24 is provided with a groove 241 for clamping the wire fixing block 23. Preferably, the groove direction of the groove 241 is the same as the groove direction of the wire clamping groove 231. The width and height of the plurality of wire fixing blocks 23 are the same, so it is only necessary to clamp the wire fixing block 23 where the wire clamping groove 231 matching the specification of the wire 9 is located in the groove 241. When replacing, it is only necessary to take out the wire fixing block 23 from the groove 241 and place the wire fixing block 23 with a wire clamping groove 231 of another specification in the groove 241. The replacement is quick and convenient.

[0039] In another optional embodiment, the wire fixing block 23 may also be directly fixed to the top of the support plate 11 by screws, and the wire fixing block 23 may be replaced by removing the screws.

[0040] Optionally, a vertically arranged guide column 15 is also fixed on the support seat 1, and the pressing block 21 is sleeved on the guide column 15 and slides up and down along the guide column 15. There are two guide columns 15, the bottom of which is fixed on the fixed base 24, and the two guide columns 15 are respectively arranged near two opposite sides of the pressing block 21 to play a guiding role.

[0041] like Figure 1 , 2 As shown in Figures 5 and 6, the second clamping mechanism 3 is rotatably connected to the winding portion 41 through a sleeve rod 7 sleeved on the winding portion 41, and the sleeve rod 7 is detachably connected to the support seat 1. Figure 5 As shown, the sleeve rod 7 is in a stepped cylindrical shape, including a large diameter portion 71 and a small diameter portion 72, the large diameter portion 71 is arranged above the small diameter portion 72, and the end of the second clamping mechanism 3 close to the first clamping mechanism 2 is sleeved on the small diameter portion 72 and is located between the large diameter portion 71 and the support seat 1. Figure 5 As shown, a threaded hole is provided on the support plate 11, and an external thread is provided at the bottom end of the small diameter portion 72. The bottom end of the small diameter portion 72 extends into the threaded hole on the support plate 11 and is threadedly connected to the support plate 11, so as to realize the detachable connection between the sleeve rod 7 and the support plate 11. The small diameter portion 72 can also be set in a stepped shape, with the larger diameter portion being located above the support plate 11 and sleeved inside the second clamping mechanism 3, and the smaller diameter portion being threadedly connected to the support plate 11. The large diameter portion 71 is located above the end of the second clamping mechanism 3 close to the first clamping mechanism 2, and the end of the second clamping mechanism 3 is limited between the large diameter portion 71 and the support plate 11 to prevent the second clamping mechanism 3 from moving upward when rotating, so as to ensure that the bending section formed by the electric wire 9 wound on the winding portion 41 is in the same plane, that is, the radius of the bending is kept the same, thereby improving the accuracy of performance testing.

[0042] The inner diameter of the sleeve rod 7 has various specifications to match the outer diameter of the winding part 41. The inner diameter of the sleeve rod 7 is slightly larger than the outer diameter of the matching winding part 41 but smaller than the outer diameter of the wire pressing part 42, so as to avoid the inner diameter of the sleeve rod 7 being too large, causing the winding part 41 to shake and tilt inside the sleeve rod 7 when moving up and down, that is, to ensure that the central axis of the winding part 41 is in the same position and remains vertical, thereby improving the accuracy of bending.

[0043] The top of the sleeve rod 7 is flush with the bottom of the wire slot 231, ensuring that the wire 9 is in a horizontal state. The winding part 41 moves up and down along the inner cavity of the sleeve rod 7 by an appropriate distance according to the specifications of the wire 9, clamping the wire 9 between the wire pressing part 42 and the sleeve rod 7 to prevent the bent part of the wire 9 from arching and curling during the bending process.

[0044] like Figure 1 , 2 , 4 and 6, the second clamping mechanism 3 includes a bottom plate 31, a top plate 32 and a side baffle 33. The end of the bottom plate 31 close to the first clamping mechanism 2 is rotatably connected to the winding portion 41, and the end of the bottom plate 31 close to the first clamping mechanism 2 is sleeved on the small diameter portion 72 of the sleeve rod 7, as shown in FIG. Figure 1 and 2 As shown, the end of the bottom plate 31 close to the first clamping mechanism 2 can also be set to a step shape matching the sleeve rod 7, the step surface is pressed below the large diameter portion 71, and the vertical surface on the side of the large diameter portion 71 is an arc surface matching the large diameter portion 71, so that it can rotate around the large diameter portion 71. The side baffle 33 is set on the side of the bottom plate 31 and is movably connected to the bottom plate 31. The top of the side baffle 33 is higher than the top of the bottom plate 31. The side baffle 33 moves in the direction of approaching or moving away from the bottom plate 31. The wire 9 is placed on the bottom plate 31. The side baffle 33 moves in the direction of approaching or moving away from the bottom plate 31 according to the specifications of the wire 9 to adjust the position, and the side baffle 33 blocks the side of the wire 9. The top plate 32 is arranged on the top of the side baffle 33 and is movably connected with the side baffle 33. The top plate 32 extends to the top of the bottom plate 31. The top plate 32 moves in the direction close to or away from the bottom plate 31 and the side baffle 33. The top plate 32 moves up and down by a suitable distance according to the specifications of the wire 9 and presses on the wire 9. The bottom plate 31 and the side baffle 33 clamp the wire 9 from three directions to prevent the wire 9 from moving relative to the second clamping mechanism 3 when the wire 9 is carried. The top surface of the bottom plate 31 outside the large diameter portion 71 is flush with the top surface of the sleeve rod 7, ensuring that the wire 9 is in a horizontal state and improving the accuracy of the bending and performance tests.

[0045] Optional, such as Figure 4 and 6 As shown, the side baffle 33 is L-shaped, the vertical portion of the side baffle 33 is located on the side of the bottom plate 31, the horizontal portion of the side baffle 33 extends above the bottom plate 31, and the horizontal portion of the side baffle 33 contacts the wire 9 and blocks the side of the wire 9.

[0046] like Figure 6 As shown, the side baffle 33 is movably connected to the bottom plate 31 through a first connecting component 34, and the first connecting component 34 includes a first connecting rod 341, a first limit block 342 and a first spring 343. One end of the first connecting rod 341 is fixedly connected to the bottom plate 31, and the first limit block 342 is fixed to the other end of the first connecting rod 341. The side baffle 33 is sleeved on the first connecting rod 341 and can slide along the first connecting rod 341. The first spring 343 is sleeved on the first connecting rod 341 and is located between the side baffle 33 and the bottom plate 31. The two ends of the first spring 343 are fixedly connected to the bottom plate 31 and the side baffle 33 respectively; that is, the first spring 343, the side baffle 33 and the first limit block 342 are arranged in sequence on the first connecting rod 341 in a direction away from the bottom plate 31. In the initial state, the first spring 343 is in a natural state, which is the state in which the horizontal distance between the side baffle 33 and the bottom plate 31 is the smallest. The vertical part of the side baffle 33 is sleeved on the first connecting rod 341. When placing the wire 9, the side baffle 33 can be pulled in the direction away from the bottom plate 31. The first spring 343 is in a stretched state. After the wire 9 is placed, the side baffle 33 is released. Under the action of the restoring elastic force of the first spring 343, the side baffle 33 moves in the direction close to the bottom plate, clamping the wire 9 between the winding part 41 and the side baffle 33. The first limit block 342 limits the maximum distance of the side baffle 33 moving in the direction away from the bottom plate 31. In this embodiment, the first connecting rod 341 is threadedly connected to the bottom plate 31. The first connecting rod 341 and the first limit block 342 can be directly bolted. The first connecting rod 341 and the bottom plate 31 are threadedly connected to each other, and the distance between the bottom plate 31 and the first limit block 342 can also be adjusted.

[0047] like Figure 6As shown, the top plate 32 is movably connected to the side baffle 33 through a second connecting assembly 35, and the second connecting assembly 35 includes a second connecting rod 351, a second limit block 352 and a second spring 353. The bottom end of the second connecting rod 351 is fixedly connected to the top of the side baffle 33, and the second limit block 352 is fixed to the top of the second connecting rod 351. The top plate 32 is sleeved on the second connecting rod 351 and can slide along the second connecting rod 351. The second spring 353 is sleeved on the second connecting rod 351 and is located between the top plate 32 and the side baffle 33. The two ends of the second spring 353 are fixedly connected to the top plate 32 and the side baffle 33 respectively, that is, the second spring 353, the top plate 32 and the second limit block 352 are arranged in sequence from bottom to top on the second connecting rod 351. In the initial state, the second spring 353 is in a natural state, which is the state where the distance between the top plate 32 and the bottom plate 31 is the smallest. When placing the wire 9, the top plate 32 can be pulled upward in a direction away from the bottom plate 31 and the side baffle 33, and the second spring 353 is in a stretched state. After the wire 9 is placed, the top plate 32 is released. Under the action of the restoring elastic force of the second spring 353, the top plate 32 moves downward and presses on the top of the wire 9, clamping the wire 9 between the top plate 32 and the bottom plate 31. The second limit block 352 limits the maximum distance that the top plate 32 moves in a direction away from the bottom plate 31. In this embodiment, the second connecting rod 351 is threadedly connected to the side baffle 33, and the second connecting rod 351 and the second limit block 352 can be directly bolted. The second connecting rod 351 is threadedly connected to the side baffle 33 and can also adjust the distance between the side baffle 33 and the second limit block 352, that is, adjust the maximum distance between the bottom plate 31 and the top plate 32.

[0048] Optional, such as Figure 1 , 2 As shown in FIGS. 4 and 5, a rotating handle 36 is fixed to one end of the bottom plate 31 away from the winding rod 4, and the rotating handle 36 extends outside the support seat 1 to facilitate the rotating operation. In the initial state, the rotating handle 36 is located on the connecting line of the first clamping mechanism 2 and the second clamping mechanism 3. The rotating handle 36 is provided with anti-slip grooves.

[0049] When the driving mechanism 22 and the sliding driving mechanism 5 are pneumatic cylinders, a pneumatic valve 8 can be set, and the pneumatic valve 8 is fixed on the support plate 11. The driving mechanism 22, the sliding driving mechanism 5 and the pneumatic valve 8 are connected together, and the pressure of the pneumatic valve 8 is adjusted to an appropriate value, so that the stroke of the driving end of the driving mechanism 22 and the sliding driving mechanism 5 can be controlled.

[0050] Optionally, an angle scale is provided on the top surface of the support plate 11 around the winding portion 41. The angle scale can be provided on the periphery of the base plate 31. The wire segment extending outside the second clamping mechanism and close to the rotating handle 36 can be directly used as a pointer. In the initial state, the wire segment points to the 0° scale line of the angle scale. The angle scale pointed to by the wire segment clamped by the second clamping mechanism displays the bending angle of the wire 9.

[0051] The method of using the wire bending device of the embodiment of the present application to bend the wire 9 for performance testing is as follows:

[0052] According to the bending radius, a winding post 4 with a winding part 41 of suitable outer diameter and a sleeve rod 7 of matching specifications are selected. The sleeve rod 7 is connected to the support plate 11. The winding part 41 of the winding post 4 is inserted into the sleeve rod 7 and the bottom is connected to the second adapter block 67. According to the specifications of the wire 9 to be tested, a wire fixing block 23 with a wire slot 231 of suitable specifications is selected and installed in the fixed base 24. One section of the wire 9 is clamped in the wire slot 231, and the pressing block 21 is driven downward by the driving mechanism 22 to press on the top of the wire 9. The wire 9 is in a straight state. The other section of the wire 9 is placed on the bottom plate 31 and is clamped with the bottom plate 31 by the side baffle 33 and the top plate 32. At this time, the wire 9 is close to the side of the winding part 41. The winding part 41 is driven downward by the sliding driving mechanism 5 to press the wire pressing part 42 on the wire 9, and the wire 9 is fixed. Then, hold the rotating handle 36 to drive the second clamping mechanism 3 and the wire segment on the second clamping mechanism 3 to rotate around the winding part 41, and wind the wire 9 on the winding part 41 to achieve the bending of the wire 9. The rotation angle of the second clamping mechanism 3 and the wire 9 is determined by the angle scale pointed by the wire segment close to the rotating handle 36. When the angle value is rotated to the specified angle value, the rotation is stopped, so that the wire 9 is bent at the specified angle. After the winding is stopped, the side baffle 33 and the top plate 32 can be pulled away from the bottom plate 31 to release the wire 9 and make the wire 9 rebound naturally. When the wire 9 no longer rebounds, the angle scale pointed by the wire segment close to the rotating handle 36 can be observed, so as to calculate the rebound angle and judge whether the flexibility meets the requirements; check whether there are cracks on the surface coating where the wire 9 is wound to determine the tensile properties of the coating.

[0053] When the performance test of the wire 9 is performed next time, the winding column 4, the sleeve rod 7 and the wire fixing block 23 can be replaced according to the bending radius and the specifications of the wire 9, and the above clamping and winding steps are repeated to complete the test of another wire 9. The whole test process is simple and can be completed by one person, which improves the flexibility and precision of the test and improves the work efficiency.

[0054] The wire bending device of the present application can adapt to the variability of on-site operations and can be adjusted at any time to cope with the changes brought about by wires 9 of different specifications; in terms of resources, it is only necessary to replace the wire fixing block 23 (to adapt to wires 9 of different specifications) and / or replace the winding pole 4 (which can be used for different bending radii) each time, thereby greatly reducing the cost brought by processing; in terms of operation, the components of the wire bending device can be disassembled and adjusted at any time, and the mechanical characteristics of the driving mechanism 22 and the sliding driving mechanism 5 are utilized to save manpower and material resources and improve work efficiency.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and simple improvement made to the essential content of the present invention shall be included in the protection scope of the present invention.
