[0033] Example 1
[0034] See Figures 1 to 6 This utility model provides a portable cable bending tool, including a fixing part 1 and a bending part 2;
[0035] The fixing component 1 includes a fixing rod 3, a fixing seat 4 is fixedly installed at one end of the fixing rod 3, a bending die 5 is installed on the fixing seat 4, the bending die 5 includes a mounting plate 6 fixedly installed on the fixing seat 4, a slider 7 is arranged in a circumferential array on the mounting plate 6, and a first bending block 8, a second bending block 9 and a third bending block 10 are arranged sequentially on the slider 7, and a first line groove 11 is opened on the first bending block 8, the second bending block 9 and the third bending block 10;
[0036] According to the required cable bending radius, adjust the position of the slider 7 around the mounting plate 6, and achieve different bending radius settings by changing the distance between the first bending block 8, the second bending block 9 and the third bending block 10 and the axis.
[0037] The bending component 2 includes a rotating seat 12 and a bending rod 13. A connecting rod 14 is fixedly installed on the rotating seat 12, and the movable end of the connecting rod 14 is rotatably connected to the fixed seat 4.
[0038] The rotating seat 12 is provided with a second line groove 15, and the bending rod 13 can drive the second line groove 15 to rotate along the first line groove 11 and thus bend the cable.
[0039] The operator holds the bending rod 13 and applies force, causing the rotating seat 12 to rotate around the axis of the connecting rod 14. The second line groove 15 works in conjunction with the first line groove 11 to form a closed-loop guide. Through the progressive guidance of the three sets of bending blocks, the cable undergoes plastic deformation along the set radius under the constraint of the groove.
[0040] The radial adjustment of slider 7 enables multi-radius output from a single mold, achieving multiple uses in one machine and reducing equipment costs.
[0041] A groove is provided on the mounting plate 6, and the slider 7 slides within the groove;
[0042] The projections of two adjacent slides on the vertical plane are perpendicular, and both slides are located in the upper half of the mounting plate 6.
[0043] A worm gear 16 is also rotatably installed inside the slide groove. Several toothed grooves are provided on the side wall of the slider 7 adjacent to the worm gear 16, and the toothed grooves mesh with the worm gear 16.
[0044] The position of slider 7 on mounting plate 6 can be adjusted by adjusting worm gear 16, and worm gear 16 has a self-locking characteristic, so the position of slider 7 will not change after adjustment.
[0045] A drive bevel gear 17 is rotatably mounted in the middle of the mounting plate 6. Several driven bevel gears 18 mesh with the drive bevel gear 17. Each driven bevel gear 18 is coaxially fixed with an adjacent worm gear 16.
[0046] A drive rod 19 is also fixedly installed in the middle of the mounting plate 6, and a hexagonal slot is provided at one end of the drive rod 19.
[0047] The user inserts a hexagonal wrench into the hexagonal slot and rotates the hexagonal wrench to drive the driving bevel gear 17 to rotate, which in turn drives several driven bevel gears 18 to rotate, so that the driven bevel gears 18 rotate synchronously and all sliders 7 move radially synchronously.
[0048] Furthermore, annular scale lines are set on the side wall of the mounting plate 6. By observing the position of the slider 7, the distances of the first bending block 8, the second bending block 9, and the third bending block 10 from the axis can be determined.
[0049] The first cable groove and the second line groove 15 both include several bending grooves of different diameters, with the diameter of the bending grooves gradually decreasing from the side closer to the connecting rod 14 to the side farther away from the connecting rod 14.
[0050] Select the appropriate bending groove according to the cable diameter. A single device can cover the bending needs of cables with different diameters. It can adapt to multiple wire diameters without changing the mold, realize multiple uses of one machine, and reduce the cost of equipment.
[0051] The first bending block 8 includes a vertical part and a bent part, and a bent pipe column 20 is fixedly installed on the vertical part of the first bending block 8.
[0052] The bend post 20 and the vertical part cooperate to form a right-angle positioning surface to ensure the verticality of the cable bending start end;
[0053] The second bending block 9 and the third bending block 10 are both arc-shaped, and angle markings are provided on the side walls of the first bending block 8, the second bending block 9 and the third bending block 10.
[0054] When the bending die 5 is at its minimum bending radius, the bent portions of the first bending block 8, the second bending block 9, and the third bending block 10 form a semi-circle. As the bending radius is gradually adjusted, the first bending block 8, the second bending block 9, and the third bending block 10 expand outward synchronously along the mounting plate 6, forming an intermittent state with a larger diameter. As the first bending block 8, the second bending block 9, and the third bending block 10 expand outward, a continuous gradient curvature profile is formed through the combination of discrete curvature units of the first bending block 8, the second bending block 9, and the third bending block 10.
[0055] This design breaks through the shape limitations of traditional single-circular arc molds. While ensuring the cable bending radius meets the specifications, it allows for a certain range of adjustment, which can flexibly adapt to the construction needs of non-standard bending paths in substations, power distribution rooms and other scenarios. It is particularly suitable for complex power engineering scenarios that require the bending of multiple cable specifications.
[0056] A sliding rod 21 is fixedly installed on the side of the first bending block 8 away from the bending column 20, and a sleeve 22 is fixedly installed on the fixed seat 4. The sliding rod 21 slides inside the sleeve 22.
[0057] The sliding rod 21 and sleeve 22 can increase the structural strength of the first bending block 8. During the bending process, the first bending block 8 bears a large bending moment. The presence of the sliding rod 21 can transfer part of the force to the sleeve 22 and the fixed seat 4, avoiding stress concentration on the first bending block 8 and the slider 7 itself, and extending the service life of the device.
[0058] Indicator lines are provided on the side wall of the rotating base 12.
[0059] When the indicator line corresponds to the angle line, the current angle of bending can be determined.
[0060] The connecting rod 14 has several positioning holes 23 on its body, and the fixing seat 4 has a threaded hole. The threaded hole is connected to a screw rod, and the screw rod corresponds to one of the positioning holes 23.
[0061] A knob 24 is fixedly installed at one end of the screw.
[0062] When adjusting the bending radius of the bending die 5, the screw is inserted into the corresponding positioning hole 23 to ensure that the distance between the first line groove 11 and the second line groove 15 corresponds to the diameter of the cable. When the bending rod 13 rotates, it can drive the second line groove 15 to rotate along the first line groove 11 and thus bend the cable.
[0063] Both the fixed rod 3 and the bent rod 13 are equipped with handle sleeves at their ends.
[0064] When using this utility model, the position of the slider 7 is adjusted along the circumference of the mounting plate 6 according to the required cable bending radius. Different bending radii can be set by changing the distance between the first bending block 8, the second bending block 9 and the third bending block 10 and the axis.
[0065] The operator holds the bending rod 13 and applies force, causing the rotating seat 12 to rotate around the axis of the connecting rod 14. The second line groove 15 works in conjunction with the first line groove 11 to form a closed-loop guide. Through the progressive guidance of the three sets of bending blocks, the cable undergoes plastic deformation along the set radius under the constraint of the groove.
[0066] The radial adjustment of slider 7 enables multi-radius output from a single mold, achieving multiple uses in one machine and reducing equipment costs.
[0067] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
