Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy stranded wire processing devices, in particular to an aluminum alloy stranded wire stress release device. Background Art

[0002] According to the patent document with the publication number CN212587256U, the stress in the vertical direction of the aluminum alloy stranded wire of the cable is eliminated by allowing the first repair wheel and the second repair wheel (or the third repair wheel) to extrude the aluminum alloy stranded wire in a relative and staggered manner;

[0003] This patent document eliminates stress in aluminum alloy stranded wire by simply extruding it in one direction, but does not eliminate stress in the direction perpendicular to the vertical direction. Furthermore, during the production of aluminum alloy stranded wire, since the aluminum alloy stranded wire is made of a single main wire wrapped around multiple branches, there are not only stresses in the vertical direction and perpendicular to the vertical direction on the multiple branches outside the main wire, but also stresses that do not coincide with the vertical direction and perpendicular to the vertical direction on the spiral branches. Therefore, simply relying on extrusion in two directions will cause stress in the cable aluminum alloy stranded wire. Utility Model Content

[0029] In this embodiment: the stress release mechanism 3 includes a fixed frame 31, a rotating sleeve 33 is rotatably connected to the upper side of the fixed frame 31, a plurality of extrusion mechanisms 4 are arranged opposite and staggered on both sides of the rotating sleeve 33, a worm gear 35 is arranged in the middle of the rotating sleeve 33, a worm 34 for driving the worm gear 35 to rotate is arranged on the lower side, a rotating motor 32 is fixedly arranged at the input end of the worm 34, a cable aluminum alloy stranded wire 6 is arranged at the center of the rotating sleeve 33, the lower end of the fixed frame 31 is fixed to the middle position of the top of the bottom plate 5, a first through hole for rotating the rotating sleeve 33 is opened on the upper side of the fixed frame 31, the worm 34 is rotatably connected to the fixed frame 31, the fixed part of the rotating motor 32 is fixedly connected to the rotating sleeve 33, and the fixed An annular groove for the rotation of the worm wheel 35 is provided in the first through hole of the fixed frame 31, and second through holes for supporting the two ends of the rotating sleeve 33 are provided on the first bracket 1 and the second bracket 2. Balls for supporting the ends of the rotating sleeve 33 are provided in the second through holes of the first bracket 1 and the second bracket 2. The rotating part of the rotating motor 32 is used to drive the worm 34 to rotate, and the rotating sleeve 33 is driven to rotate in the first through hole of the fixed frame 31 through the cooperation of the worm 34 and the worm wheel 35. The rotation of the rotating sleeve 33 allows multiple extrusion mechanisms 4 to rotate and roll the cable aluminum alloy stranded wire 6, so that the cable aluminum alloy stranded wire 6 is slightly bent during the rolling process, thereby reducing the stress in the aluminum alloy stranded wire.

[0030] In this embodiment, the extrusion mechanism 4 includes a screw rod 41, which is threadedly connected to the rotating sleeve 33. One end of the screw rod 41 extending into the rotating sleeve 33 is rotatably connected to a pressing frame 43, and a pressing wheel 44 is detachably connected to the inner side of the pressing frame 43. Two sliding rods 45 parallel to the screw rod 41 are arranged on the outer side of the pressing frame 43. A locking nut 42 is threadedly connected to the screw rod 41, and the locking nut 42 is located on the outer side of the rotating sleeve 33. The multiple pressing wheels 44 in the rotating sleeve 33 are all arranged along the twisting direction of the cable aluminum alloy stranded wire 6. The screw rod 41 extends A hand wheel for driving the rotation of the rotating sleeve 33 is fixed at one end thereof, and a groove for increasing the contact area with the cable aluminum alloy stranded wire 6 and maintaining its roundness is provided on the pressure wheel 44, and the pressure wheel 44 is made of nylon material. The screw 41 is screwed into the rotating sleeve 33 to adjust the distance between the two relative clamping frames 43 and the pressure wheel 44 according to the diameter of the cable aluminum alloy stranded wire 6, and the locking nut 42 is used to lock the rotated screw 41 to prevent the screw 41 from rotating in the opposite direction while following the rotation of the rotating sleeve 33.

[0031] Working principle: When in use, firstly, the cable aluminum alloy stranded wire 6 that needs to release stress is passed through one end of the rotating sleeve 33 and passed through the other end of the rotating sleeve 33, and then one end of the cable aluminum alloy stranded wire 6 is installed on the winding device, and then the screws 41 on both sides of the rotating sleeve 33 drive the clamping frame 43 and the pressure wheel 44 to press against the outside of the cable aluminum alloy stranded wire 6, and the cable aluminum alloy stranded wire 6 is slightly bent by the pressure wheels 44 arranged in an interlaced manner. After the position adjustment of the clamping frame 43 is completed, the locking nut 42 is rotated to make it fit with the outside of the rotating sleeve 33 to lock the screw 41, thereby preventing the screw 41 from rotating loosely during the rotation of the rotating sleeve 33, and also preventing the pressure wheel 44 from being separated from the rolling of the cable aluminum alloy stranded wire 6.

[0032] During this process, the rotating part of the rotating motor 32 is meshed with the worm gear 35 outside the rotating sleeve 33 through the worm 34 to drive the rotating sleeve 33 to rotate around the cable aluminum alloy stranded wire 6 as the center. When the rotating sleeve 33 rotates, the rotating sleeve 33 drives the multiple extrusion mechanisms 4 on both sides thereof to rotate along the winding direction of the cable aluminum alloy stranded wire 6. Then, during the movement of the cable aluminum alloy stranded wire 6, the cable aluminum alloy stranded wire 6 is spirally rolled by the pressure wheel 44 to release its internal stress. In addition, during the rotation of the rotating sleeve 33, the cable aluminum alloy stranded wire 6 passes through the middle of the multiple pressure wheels 44 under the rotation of the winding device, thereby minimizing the stress inside the cable aluminum alloy stranded wire 6.

[0033] During the rotation of the rotating sleeve 33, both ends of the rotating sleeve 33 rotate in the second through holes of the first bracket 1 and the second bracket 2 respectively. During this process, the two ends of the rotating sleeve 33 are supported by the balls in the two second through holes, thereby reducing the friction force during the rotation of the rotating sleeve 33.

[0034] In addition, the rotating motor 32 can be rotated in the opposite direction, so that the rotating sleeve 33 can drive the multiple extrusion mechanisms 4 inside it to rotate in the opposite direction, and then the left-handed or right-handed cable aluminum alloy stranded wire 6 can be squeezed to release stress. At the same time, the pressure wheels 44 of different sizes on the lower side of the clamping frame 43 can be replaced to facilitate the extrusion and stress release of the cable aluminum alloy stranded wires 6 of different diameters.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
