Description

Technical Field

[0001] The present invention relates to the field of cable production equipment, and more particularly to a smooth aluminum sheath cable aluminum sheath diameter reducing device. Background Art

[0002] With the development of national economic and energy construction, the demand for electricity is increasing, the voltage transmission level is getting higher and higher, and new cable structures are constantly emerging. Smooth aluminum sheathed cable is one of them. When processing smooth aluminum sheathed cable, the aluminum sheath needs to be put on the outside of the cable core. The aluminum sheath needs to fit tightly. The aluminum sheath with interference fit is not easy to plug in, and it is also easy to cause damage to the cable core. Therefore, the aluminum sheath usually adopts a gap fit. After being put on the outside of the cable core, the aluminum sheath is reduced in diameter through a reducing equipment to achieve a close fit between the aluminum sheath and the cable core.

[0003] In the cable aluminum sheath reducing machine, the aluminum sheathed cable passes through the through holes on the base and the mounting table, and then undergoes the rolling action of the rolling wheel assembly to compress the aluminum sheath to the required outer diameter. The design and layout of the rolling wheel assembly ensure that the aluminum sheath is subjected to uniform rolling force at multiple angles, thereby achieving comprehensive and effective diameter reduction.

[0004] However, when the aluminum sheathed cable passes through the rolling wheel group, if there are impurities on the outer surface of the cable, the presence of impurities may affect the reduction effect and the overall quality of the cable. The operator is unable to quickly discover and deal with the impurities on the surface of the aluminum sheath, which increases friction and wear with equipment components. For this reason, we propose a smooth aluminum sheathed cable aluminum sheath reduction device. Summary of the Invention

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0032] like Figure 1 - Figure 9 As shown, a smooth aluminum sheath cable aluminum sheath reducing device includes: an aluminum sheath reducing machine 11, four mutually symmetrical rolling wheels 12 are cross-distributed at the center of the aluminum sheath reducing machine 11, and a brushing mechanism 2 is provided on one side of the wire inlet of the aluminum sheath reducing machine 11 to remove foreign matter from the outer surface of the cable aluminum sheath entering the wire inlet of the aluminum sheath reducing machine 11;

[0033] First, place the smooth aluminum sheathed cable at the designated position of the aluminum sheathed reducing machine 11. This position is usually carefully designed to ensure that the cable can stably and accurately enter the center of the four rolling wheels 12 of the aluminum sheathed reducing machine 11. The cable is smoothly introduced into the aluminum sheathed reducing machine 11 through the brushing mechanism 2 on one side of the aluminum sheathed reducing machine 11. After the cable enters the reducing area, the four rolling wheels 12 start working. Driven by the drive motor, the four rolling wheels 12 rotate to reduce the diameter of the smooth aluminum sheathed cable.

[0034] The brushing mechanism 2 includes two parallel gear rings 1 25 and 26 , and the inner walls of both gear rings 1 25 and 26 are provided with bristles 205 ;

[0035] Before entering the shrinking area of ​​the aluminum sheath shrinking machine 11, the smooth aluminum sheath cable will sequentially pass through the gear ring 1 25 and the gear ring 2 26 that rotate in an interlaced manner. Through the interlaced rotation of the gear ring 1 25 and the gear ring 2 26, the bristles 205 in the gear ring 1 25 and the gear ring 2 26 lightly brush the outer surface of the smooth aluminum sheath cable. The bristles 205 can continuously scrape the surface of the aluminum sheath, thereby efficiently removing impurities on the aluminum sheath. The two gear rings 1 25 and the gear ring 2 26 rotate in opposite directions, which can achieve all-round cleaning of the aluminum sheath entering the aluminum sheath shrinking machine 11. The cleaned aluminum sheath can pass through the four rolling wheels 12 more smoothly during the shrinking process, reducing friction and wear with the components of the four rolling wheels 12, thereby extending the service life of the four rolling wheels 12.

[0036] This design realizes the automatic cleaning of the aluminum sleeve without manual intervention, which improves work efficiency. The cleaning process is closely linked to the shrinking process, which reduces the downtime caused by cleaning and improves the overall efficiency of the production line.

[0037] A plurality of marking mechanisms 4 are provided between the gear ring 1 25 and the gear ring 2 26. The marking mechanism 4 includes a toothed disc 41 that meshes with the gear ring 1 25 and the gear ring 2 26. A center column 42 is provided inside the toothed disc 41. A rotating bead 44 is provided on one end of the center column 42 that rotates near the cable aluminum sheath to detect the smoothness of the cable aluminum sheath. A plurality of spray heads 48 are provided on the end face of the center column 42 to spray marks on the aluminum sheath surface at the undulation of the rotating bead 44.

[0038] By rolling the rotating bead 44 on the surface of the aluminum sleeve, impurities on the surface of the aluminum sleeve can be detected immediately. Once impurities exist on the surface of the aluminum sleeve, the fluctuation of the rotating bead 44 will immediately trigger the detection mechanism of the marking mechanism 4, and automatically spray a striking color at the fluctuation point for marking, which is convenient for subsequent manual processing or automatic removal. This design helps to timely detect and mark impurities on the surface of the aluminum sleeve before the diameter reduction process, thereby avoiding the influence of impurities on the diameter reduction effect and the overall quality of the cable.

[0039] By means of two gear rings 1 25 and 26 rotating in opposite directions and a toothed disc 41 therebetween, the toothed disc 41 rotates and moves on the gear rings 1 25 and 26, thereby achieving a zigzag path on the surface of the aluminum sleeve, which has the effect of crushing and driving the aluminum sleeve. This two-way meshing design ensures that the aluminum sleeve is subjected to uniform force during the diameter reduction process, and avoids local stress concentration and irregular deformation that may be caused by rotation in a single direction. The reciprocating rolling of the rotating ball 44 on the surface of the aluminum sleeve not only promotes the smooth movement of the aluminum sleeve, but more importantly, it effectively disperses and reduces the torsional stress generated by the aluminum sleeve during the diameter reduction process. This reciprocating pushing mechanism helps the aluminum sleeve maintain a taut state, prevents the occurrence of torsion, and improves the straightness and quality of the product.

[0040] The brushing mechanism 2 also includes an auxiliary frame 21 fixedly connected to the aluminum sleeve reducing machine 11. A wire drum 22 is fixedly provided at the center position of the auxiliary frame 21. The center of the wire drum 22 is located in the same straight line as the center of the aluminum sleeve reducing machine 11, and the cable aluminum sleeve passes through the wire drum 22 and the center position of the four rolling wheels 12 in sequence.

[0041] An extension arm 27 is fixedly provided on the side of gear ring 1 25 away from gear ring 2 26, and an elastic band 28 and a pull wire 35 are fixedly provided on both sides of the extension arm 27. One end of the elastic band 28 away from the extension arm 27 is fixedly connected to the wire drum 22, and both gear ring 1 25 and gear ring 2 26 are rotatably connected to the inner wall of the wire drum 22.

[0042] An air box 201 is fixedly provided on the side of the extension arm 27 close to the pull wire 35, and the output end of the air box 201 is fixedly connected to the air supply pipe 1 202. A plurality of air injection holes 204 are opened on the side of the gear ring 1 25 close to the gear ring 2 26, and the plurality of air injection holes 204 are interconnected with the air supply pipe 1 202.

[0043] A limiting groove 14 is provided inside the aluminum sleeve reducing machine 11 located on the side of the upper rolling wheel 12 among the four rolling wheels 12. A turntable 33 is rotatably provided inside the limiting groove 14. A torsion spring 34 is provided at the center position of the turntable 33. The turntable 33 forms a rotating structure with the aluminum sleeve reducing machine 11 through the torsion spring 34, and the turntable 33 is fixedly connected to the pull wire 35.

[0044] An L-shaped swing arm 31 is fixedly provided on one side of the turntable 33, a magnetic sheet 32 ​​is fixedly provided on the end of the swing arm 31 away from the turntable 33, and a strong magnetic block 13 is fixedly provided on the side of the rolling wheel 12 close to the limiting groove 14. The strong magnetic block 13 and the magnetic sheet 32 ​​attract each other.

[0045] After the smooth aluminum sheathed cable passes through the four rolling wheels 12, the rotation of the four rolling wheels 12 causes the strong magnetic block 13 to make a circular motion along with the rolling wheels 12. When the strong magnetic block 13 passes the magnetic sheet 32, the strong magnetic block 13 drives the magnetic sheet 32 ​​to rotate along with it. The magnetic sheet 32 ​​drives the swing arm 31 and the turntable 33 to rotate with the torsion spring 34 as the center of the circle, and the rotation of the turntable 33 tightens the pulling wire 35. Then, when the strong magnetic block 13 rotates into the interior of the aluminum sheathed reducing machine 11, the swing arm 31 is blocked and loses its adsorption force. At this time, the rebound force of the torsion spring 34 drives the turntable 33 to reverse and reset, thereby pulling the pulling wire 35 back and forth.

[0046] Each time the pull wire 35 is pulled, the extension arm 27 is pulled once. When the pull wire 35 is relaxed by the turntable 33, the extension arm 27 is pulled back to its original position by the resilience of the elastic band 28. When the pull wire 35 pulls the extension arm 27, the gear ring 1 25 is driven to rotate clockwise, which in turn drives the multiple toothed discs 41 to rotate. The multiple toothed discs 41 drive the gear ring 26 to rotate counterclockwise. The bristles 205 in the gear ring 26 clean the surface of the smooth aluminum sheathed cable for the first time, and the bristles 205 in the gear ring 1 25 clean the surface of the smooth aluminum sheathed cable for the second time.

[0047] When the gear ring 1 25 rotates clockwise, the extension arm 27 squeezes the air box 201, so that the air in the air box 201 flows into the plurality of air injection holes 204 through the air supply pipe 1 202 and is ejected, thereby blowing air from the gear ring 1 25 toward the gear ring 2 26, blowing out the impurities cleaned by the gear ring 2 26.

[0048] A liquid storage ring 23 is fixedly provided on the wire barrel 22 , an elastic liquid injection rubber head 29 is fixedly provided at the input end of the liquid storage ring 23 , and a plurality of expansion rubber sheets 24 are fixedly provided on the outer wall of the liquid storage ring 23 for applying pressure to the inside of the liquid storage ring 23 .

[0049] A blocking ball 49 is movably provided inside the liquid spray head 48 , and a control wire 401 is fixedly provided on the blocking ball 49 . Liquid inlet ends of the plurality of liquid spray heads 48 are fixedly connected to a liquid flow pipe 402 .

[0050] A liquid storage chamber 403 opened inside the middle column 42 is provided at one end of the liquid flow tube 402 away from the liquid spray head 48, and the liquid inlet end of the liquid storage chamber 403 is connected to the liquid inlet tube 43. The liquid spray head 48, the liquid flow tube 402, the liquid storage chamber 403 and the liquid storage ring 23 are interconnected.

[0051] A lower pressure plate 45 is provided above the rotating ball 44, and the arc angle of the lower pressure plate 45 is the same as that of the rotating ball 44. A lifting column 46 is fixedly provided above the lower pressure plate 45 and is slidably connected to the middle column 42. The top plate of the lifting column 46 is fixedly connected to the end of the plurality of control wires 401 away from the blocking ball 49. A spring 47 is provided on the outer sleeve of the lifting column 46.

[0052] A syringe is used to penetrate the injection rubber head 29 and inject colored liquid into the liquid storage ring 23. As the amount of liquid injected increases, the multiple expandable rubber sheets 24 gradually expand and exert pressure on the liquid. The liquid flows along the liquid inlet pipe 43 into the multiple liquid storage chambers 403, and then flows along the liquid flow pipe 402 into the multiple liquid spray heads 48.

[0053] The rotation of the toothed disc 41 drives the rotating bead 44 to rotate, and the rotating bead 44 just contacts the surface of the smooth aluminum sheathed cable. Once there are impurities on the surface of the aluminum sheath, the rotating bead 44 fluctuates, and the lower pressure plate 45 is squeezed by the rotating bead 44. The lower pressure plate 45 is pulled, which immediately triggers the detection mechanism of the marking mechanism 4, and automatically sprays a striking color at the fluctuation point to mark the control wire 401. The blocking ball 49 is pulled by the control wire 401, so that the colored liquid is sprayed around the impurities on the surface of the smooth aluminum sheathed cable.

[0054] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
