DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] In the drawings, the same reference numerals all refer to the same components.

[0023] like Figure 1-3 As shown, the utility model provides a shaping tool for welding a cable metal sleeve, comprising a base 1, at least one bending assembly 2, a cable core limiting assembly 3 and two sets of ring assemblies 4, wherein the bending assembly 2, the cable core limiting assembly 3 and the two sets of ring assemblies 4 are sequentially arranged at intervals on the top of the base 1;

[0024] The press-bending assembly 2 includes a first mounting frame 21, which is arranged at the top of the base 1. A first press-bending roller 22 and a second press-bending roller 23 are rotatably installed in the first mounting frame 21. The second press-bending roller 23 is located above the first press-bending roller 22 and can move in the first mounting frame 21 to adjust the distance between the second press-bending roller 23 and the first press-bending roller 22.

[0025] In this embodiment, one end of the cut metal coil is passed through the gap between the first bending roller 22 and the second bending roller 23 of at least one bending assembly 2, and the metal coil is bent into an arc shape with a downward depression in the middle, so as to facilitate the subsequent shaping of the metal coil;

[0026] After the cable core passes through the cable core limiting assembly 3, it contacts the bent metal coil, and then enters the two-component ring assembly 4 in sequence. The metal coil is covered on the outer surface of the cable core through the ring assembly 4, and a joint for welding is formed on the top of the metal coil.

[0027] Furthermore, both sides of the first mounting frame 21 are provided with slide grooves 24, and each slide groove 24 is provided with a slider 25 that can slide in the corresponding slide groove 24. The two ends of the second bending roller 23 are rotatably connected to the two sliders 25 through bearings, and the two ends of the first bending roller 22 are rotatably connected to the two sides of the first mounting frame 21 through bearings.

[0028] In this embodiment, the height of the sliders 25 in the two slide grooves 24 is adjusted to change the height of the second bending roller 23, thereby changing the distance between the first bending roller 22 and the second bending roller 23 to adapt to metal coils of different thicknesses;

[0029] If the metal coil is thicker, multiple bending assemblies 2 need to be provided to bend the metal coil in a progressive manner until the metal coil reaches a suitable curvature.

[0030] Furthermore, each slide groove 24 is provided with a vertical first screw rod 26 , the bottom end of which is rotatably connected to the corresponding slider 25 and is threadedly connected to the top of the first mounting bracket 21 to adjust the position of the slider 25 in the slide groove 24 .

[0031] In this embodiment, a hand wheel is fixedly connected to the top end of the first screw rod 26. Turning the hand wheel can enable the first screw rod 26 to drive the slider 25 to move vertically in the slide groove 24, thereby changing the height of the second bending roller 23, and then changing the spacing between the first bending roller 22 and the second bending roller 23. The two ends of the slider 25 are slidably connected to the inner wall through holes of the corresponding slide groove 24, or an optical axis (not shown in the figure) is provided at the top end of the slider 25 to prevent the slider 25 from rotating when the first screw rod 26 is rotated.

[0032] Furthermore, the cable core limiting assembly 3 includes a second mounting frame 31, which is arranged at the top of the base 1. A cable core pressing roller 32 is provided at the top of the second mounting frame 31, and a meter counter 33 is also provided on its outer wall. Both ends of the cable core pressing roller 32 are rotatably connected to the inner wall of the second mounting frame 31 through bearings, and one end thereof is coaxially connected to the axis of the meter counter 33.

[0033] In this embodiment, the cable core passes through the top of the bending assembly 2 and enters the first looping assembly 4 to contact the metal coil. Before this, the cable core enters the second mounting frame 31 and passes under the cable core pressing roller 32. The middle part of the cable core pressing roller 32 has a depression, which can reduce the left and right displacement of the cable core when the cable core moves, so that the metal coil can better contact with the cable core.

[0034] After the cable core is covered with the metal sheath, it needs to be welded and textured. The textured cable is not easy to measure, so one end of the cable core pressing roller 32 is coaxially connected to the axis of the meter 33 using the prior art, so that the cable core can be measured when the cable core drives the cable core pressing roller 32 to rotate.

[0035] Furthermore, the ring-forming assembly 4 includes a fixed frame 41, a fixed block 42, a movable block 43 and a shaping ring 44. The fixed frame 41 is arranged at the top of the base 1. The fixed frame 41 and the movable block 43 are both arranged in the fixed frame 41, and both are provided with a notch adapted to the shaping ring 44. The shaping ring 44 is placed between the fixed frame 41 and the movable block 43, and is stuck in the notch.

[0036] In this embodiment, the shaping ring 44 is placed in the notch of the fixing frame 42, and then the movable block 43 is pressed on the shaping ring 44 to fix the shaping ring 44;

[0037] The shaping ring 44 used in a ring-forming component 4 close to the cable core limiting component 3 is larger, while the shaping ring 44 used in a ring-forming component 4 far away from the cable core limiting component 3 is adapted to the outer diameter of the cable core coated with a metal layer, so as to facilitate the shaping of the metal coil into a ring shape and cover it on the outer surface of the cable core to facilitate subsequent welding processing.

[0038] Furthermore, a vertical second screw rod 45 is disposed in the fixed frame 41 , and the bottom end of the second screw rod 45 is rotatably connected to the top end of the movable block 43 , and is threadedly connected to the top of the fixed frame 41 .

[0039] In this embodiment, a hand wheel is fixedly connected to the top end of the second screw rod 45. Turning the hand wheel can enable the second screw rod 45 to drive the movable block 43 to move vertically in the fixed frame 41, thereby changing the height of the movable block 43, and then cooperating with the fixed block 42 to clamp and fix the shaping ring 44. The two ends of the movable block 43 are slidably connected to the corresponding inner wall through holes of the fixed frame 41, or an optical axis (not shown in the figure) slidably connected to the top of the fixed frame 41 is set at the top of the movable block 43 to prevent the movable block 43 from rotating when the second screw rod 45 is rotated.

[0040] Furthermore, the first bending roller 22 and the cable core pressing roller 32 are both dumbbell-shaped, and the second bending roller 23 is spindle-shaped.

[0041] In this embodiment, the metal coil passing through the first bending roller 22 and the second bending roller 23 can be bent by the dumbbell-shaped first bending roller 22 and the spindle-shaped second bending roller 23 matched therewith, and the bent shape is concave in the middle, so that the metal coil can subsequently enter the shaping ring 44 to be shaped into a ring and covered on the outer surface of the cable core;

[0042] The dumbbell-shaped cable core pressing roller 32 can confine the cable core in the middle thereof to prevent the cable core from swinging too much left and right when moving.

[0043] The utility model relates to a shaping tool for welding cable metal sleeves. By rotating a first screw rod, a slider can be driven to adjust the spacing between a second bending roller and a first bending roller, thereby adapting to bending coils of different thicknesses, thereby increasing the shaping efficiency of the metal layer; by replacing the shaping rings in the ring assembly with different inner diameters, the metal layer covering of cable cores of different outer diameters can be adapted, thereby increasing the shaping efficiency of the metal layer.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
