[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0026] Large-section rigid cables require bending during the fabrication of terminations or joints. Currently, the common practice for cable terminations is to bend the cable manually. However, due to the large cross-sectional area and rigid conductor of the cable, this method typically requires two or more workers, resulting in high labor costs. Furthermore, manual bending can lead to sharp bends and inaccurate bending radii, failing to meet manufacturing standards. The insulation layer is compressed, resulting in thinner insulation at the bend, creating a safety hazard. When manually bending three-phase cables, the bending radius cannot be guaranteed to be consistent, causing the cable terminals to be misaligned, requiring readjustment during installation. Inaccurate bending radii at the bend points also make it difficult to bend the cable with varying radii.
[0027] In view of this, the cable bending device provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.
[0028] Please refer to Figures 1 to 5 The cable bending device includes a base 1, a fixed cylinder 2 and a limiting post 3. The fixed cylinder 2 is mounted on the base 1, and the limiting post 3 is movably connected to the base 1. The limiting post 3 and the fixed cylinder 2 are spaced apart, and the distance between the limiting post 3 and the fixed cylinder 2 is adjustable.
[0029] When it is necessary to bend the cable 6, fix the base 1 to the ground or table, then place the part of the cable 6 to be bent against the outer wall of the fixed cylinder 2, pull the two ends of the cable 6 to be bent, and make the two sides of the cable 6 bend respectively lock into the limiting post 3. The whole process can be completed by one person, which is convenient and the bending radius of the cable 6 is accurate, without the "hard angle" problem caused by bending by hand. When it is necessary to bend the cable 6 with different bending radii, adjust the position of the limiting post 3, change the distance between the limiting post 3 and the fixed cylinder 2, and adjust the angle between the line connecting the limiting post 3 and the fixed cylinder 2, so as to bend the cable 6 with different bending radii.
[0030] In this embodiment, the base 1 is provided with fixing screw holes, and the base 1 can be fixed to the ground or tabletop by using fixing screws in the fixing screw holes. The base 1 can take many forms. For example, the base 1 is a plate in the shape of an isosceles triangle, with the fixing cylinder 2 set at the top corner of the plate and the two limiting posts 3 set at the bottom corner of the plate.
[0031] Specifically, the fixed cylinder 2 includes a connecting part 20 and a cylindrical part 21. The cylindrical part 21 is connected to the end of the connecting part 20, and the connecting part 20 is connected to the base 1. The cylindrical part 21 provides a position for bending the cable 6. The connecting part 20 is a screw, and the cylindrical part 21 is a cylinder with a smooth outer wall. The cylindrical part 21 is fixed to one end of the screw. Both the connecting part 20 and the cylindrical part 21 are made of hard stainless steel and are welded together. The connecting part 20 is screwed onto the base 1, and the fixed cylinder 2 is fixed to the base 1 by tightening a nut on the screw.
[0032] The outer wall of the cylindrical part 21 is provided with a wear-resistant pad. On the one hand, this prevents the cylindrical part 21 from being worn due to frequent friction. On the other hand, it also protects the cable 6 and prevents the insulation layer of the cable 6 from undergoing local thickness changes under bending. The wear-resistant pad can be made of hard rubber and then bonded to the outside of the cylindrical part 21 with high-strength adhesive. The rubber pad has a uniform thickness and a smooth surface.
[0033] Optionally, the fixed cylinder 2 is provided with vertical scales, which are distributed along the height of the fixed cylinder 2. The device suitable for different sizes of cables 6 can be quickly selected by means of the vertical scales.
[0034] refer to Figure 4 and Figure 1 The limiting post 3 includes a fixing part 30 and a limiting part 31. The fixing part 30 is connected to the end of the limiting part 31 and is connected to the base 1. The limiting part 31 and the fixing part 30 can be welded together. Both the limiting part 31 and the fixing part 30 are made of stainless steel. The base 1 is provided with a plurality of adjusting screw holes 10, which extend parallel to the bottom edge of the base 1. The plurality of adjusting screw holes 10 can be arranged at intervals or partially overlapping. The fixing part 30 is a screw rod, which is adapted to the plurality of adjusting screw holes 10, thereby ensuring that the limiting post 3 can always be fixed when it is moved and adjusted. The adjusting screw holes 10 fixed at different positions of the limiting post 3 form different line angles with the fixed cylinder 2, which is suitable for supporting cables 6 with different degrees of bending.
[0035] Of course, in addition to using the adjusting screw hole 10 to fix the limiting post 3, a sliding groove 11 can also be set on the base 1 (such as...). Figure 2The slide groove 11 is also set parallel to the bottom edge of the base 1. The fixing part 30 is still a screw. The fixing part 30 is locked in the slide groove 11 and can slide. When it is necessary to adjust the position of the limiting post 3, loosen the nut on the fixing part 30, move the limiting post 3 to the predetermined position, and then tighten the nut to fix the limiting post 3 on the base 1.
[0036] In practical use, first adjust the angle between the lines connecting the two limiting posts 3 and the fixed cylinder 2. Then, loop the cable 6 onto the outer wall of the cylindrical part 21 of the fixed cylinder 2, and pull both ends of the cable 6 to bend it. The two ends of the bent part of the cable 6 abut against the limiting posts 3 to prevent the cable 6 from recovering its deformation. Optionally, the base 1 is provided with clamping latches (not shown in the figure). The clamping latches are used to clamp the cable 6, and the bending shape of the cable 6 can be fixed by the clamping latches to prevent the cable 6 from springing back and deforming due to elasticity. The clamping latches are located near the bottom edge of the base 1, and there are two of them. The two clamping latches clamp the two sides of the bent part of the cable 6 respectively. The clamping latches can be the commonly available press-type clamping latches or wire clamps. Their specific structures are not described in detail.
[0037] refer to Figure 3 To facilitate the adjustment of the position of the limiting post 3 and achieve precise adjustment, the base 1 is provided with an angle scale 12, which is distributed on the outer periphery of the fixed cylinder 2. When it is necessary to adjust the position of the limiting post 3, the angle can be pre-divided according to the angle scale 12 and an extension line can be drawn. The extension line extends to the adjustment screw hole 10 or the slide groove 11. At this time, the limiting post 3 can be moved directly to the intersection of the extension line and the adjustment screw hole 10 or the slide groove 11 and fixed, which is very convenient and quick.
[0038] refer to Figure 5 The bending device also includes a pressure cap 4, which is detachably connected to the top of the fixed cylinder 2 and the limiting post 3. The pressure cap 4 presses the bent cable 6 firmly onto the plane of the base 1, preventing the cable 6 from warping away from the base 1 and facilitating the shaping of the cable 6. The pressure cap 4 can be a plate with multiple blind holes, corresponding to the size and shape of the top of the fixed cylinder 2 and the limiting post 3. For example, the pressure cap 4 has three blind holes, with the positions of the three blind holes corresponding to one fixed cylinder 2 and two limiting posts 3, respectively. When it is necessary to press the cable 6, the pressure cap 4 is placed on top of the base 1. Of course, the blind holes on the pressure cap 4 can also be through holes, in which case the pressure cap 4 can slide along the cylindrical part 21 of the fixed cylinder 2 and the limiting part 31 of the limiting post 3.
[0039] To facilitate the movement of the bending device, a handle 5 is also connected to the base 1, which allows workers to easily hold and move it or use clamps to hold it.
[0040] When bending the cable 6 using the bending device of this embodiment, the base 1 can be fixed and positioned first. Then, the position of the limiting post 3 can be adjusted and fixed according to the target bending angle of the cable 6. The pre-bending part of the cable 6 can be connected to the outer wall of the cylindrical part 21 of the fixed cylinder 2. Then, the two sides of the cable 6 can be pulled to bend the pre-bending part of the cable 6. The two sides of the cable 6 can be inserted into the inner side of the limiting post 3 and held against the limiting post 3. The pressure cap 4 can be pressed on the cable 6 to prevent the cable 6 from sticking up. The two sides of the bending part of the cable 6 can be clamped by the clamping lock to keep the cable 6 bent until it is shaped. The bent cable 6 can then be taken out.
[0041] The bending device of this utility model embodiment has at least the following beneficial effects: (1) It can bend cables 6 of different specifications and sizes, and can also meet the requirements of different bending radii. At the same time, it can accurately control the bending radius of cables 6.
[0042] (2) The insulation layer of cable 6 is less damaged, which can avoid the problem of "hard bend".
[0043] (3) Using the bending device of this embodiment, a worker can perform cable bending operation by himself, saving manpower.
[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
