Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and in particular relates to a chamfering device for the main insulation layer of armored cables. Background Technology

[0002] Cable insulation chamfering refers to beveling the edges of the cable insulation layer to avoid sharp 90-degree corners. The main purpose is to reduce impedance discontinuities, increase the adhesion of the cable copper foil, and improve product reliability. This process uses a special tool to cut the edge of the insulation layer to form a smooth transition bevel. For armored cables with larger diameters, hand-held cutters are usually used for chamfering. However, due to the high hardness of armored cables, it is not easy to control the cutting depth during cutting, often resulting in the cutter penetrating the insulation layer too little or too much. A structure that facilitates control of the cutting depth is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a chamfering device for the main insulation layer of armored cables, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a chamfering device for the main insulation layer of an armored cable, comprising a cutter A, the cutter A being obliquely disposed on the outside of the cable's insulation layer, the end of the cutter A near the cable being a sharp blade, and the end of the cutter A away from the cable being fixedly connected to a connector head, a plurality of inner lining plates being symmetrically disposed on the outside of the cable, the connector head being obliquely and slidably disposed on the inner lining plates, and a bolt A being rotatably connected to the end of the connector head away from the cable.

[0005] Beneficial effects

[0006] This utility model provides a chamfering device for the main insulation layer of armored cables, which has the following advantages compared with the prior art:

[0007] 1. The user inserts the end of the cable into the rotating drum from the side, with the outer wall of the cable pressed against the slot on the left side of the drum. The cable conductor passes through the slot on the right side of the drum and is secured by two arc blocks. The user can then manually tighten the cable and allow the connector to slide along its connection with the inner liner. At this point, cutter A gradually approaches the cable insulation layer. Due to the angle between cutter A and the cable's central axis, the cutting edge of cutter A begins to angle inwards from the edge of the cable insulation layer. Once bolt A can no longer be rotated, the cutting edge of cutter A is inserted to a suitable depth into the cable insulation layer. The user can then rotate the connector around the cable. Because cutter A... Figure 2With a counter-clockwise angle in terms of viewing angle, the cutting edge of tool A can rotate from the position where it is inserted into the cable insulation layer to begin cutting the insulation layer for chamfering. The chamfering is completed when the connector rotates 306°. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0014] Please see Figures 1-3 This invention provides an embodiment of a chamfering device for the main insulation layer of an armored cable, comprising a cutter A201. The cutter A201 is obliquely disposed on the outside of the insulation layer of the cable 101, and the angle between the cutter A201 and the central axis of the cable 101 is 45°. The cutter A201 is deflected counterclockwise by 15° at the end face of the insulation layer of the cable 101. The end of the cutter A201 near the cable 101 is a sharp blade, and the end of the cutter A201 away from the cable 101 is fixedly connected to a connector 203. Multiple inner lining plates 202 are symmetrically arranged on the outer side of the cable 101, and the connector 203 is obliquely slidably arranged on the inner lining plate 202; the cable 101 is a steel-armored cable with a diameter of 100mm, and because the armor layer has high hardness, the chamfered area should be ground after chamfering to remove the burrs generated by chamfering; and when chamfering, it should be ensured that the cable 101 and the rotating drum 205 are coaxial to ensure the accuracy of chamfering; at the same time, the user should lift and grind the cutting edges of the tool A201 and tool B208 to ensure the stability and smoothness of the insulation layer cutting.

[0015] In the above embodiment, the user inserts the end of cable 101 into the rotating drum 205 from the side of cable 101. At this time, the outer wall of cable 101 is tightly against the through groove 209 on the left side of the rotating drum 205, and the conductor of cable 101 passes through the through groove 209 on the right side of the rotating drum 205 and is fixed by two arc blocks 305. At this time, the user can manually pull cable 101 and make connector 203 start to slide along its connection with inner liner plate 202. That is, at this time, cutter A201 begins to gradually approach the insulation layer of cable 101. Since cutter A201 has a 45-degree angle with the central axis of cable 101, the blade of cutter A201 begins to tilt into the insulation layer of cable 101 from the edge. After the bolt A204 can no longer be turned, the blade of cutter A201 is inserted into the insulation layer of cable 101 to a suitable depth. Then the user can make connector 203 start to rotate around cable 101. Figure 2 With a counterclockwise 15-degree angle of view, the cutting edge of the tool A201 can rotate from the position where it is inserted into the insulation layer of the cable 101 to begin cutting the insulation layer for chamfering. The chamfering is completed when the connector 203 rotates 360°.

[0016] Specifically, a bolt A204 is rotatably connected to the end of the connector 203 away from the cable 101, and the bolt A204 and the cutter A201 are on the same plane. The bolt A204 is threadedly connected to the rotating drum 205, and the end of the bolt A204 passes through the rotating drum 205. Both bolt B207 and bolt A204 should have a self-locking effect to increase their stability after rotation. At the same time, their rotating ends should be hexagonal to facilitate the user to use tools such as wrenches to clamp the rotating ends and make it easy to rotate.

[0017] In the above embodiment, by manually tightening the bolt A204, the bolt A204 begins to push the connector 203 that is rotatably connected to it, that is, at this time the blade of the cutter A201 begins to tilt and insert into the insulation layer of the cable 101.

[0018] Specifically, multiple inner lining plates 202 are symmetrically fixedly connected inside the rotating drum 205, and the rotating drum 205 is rotatably connected to the frame 301. Both sides of the rotating drum 205 are provided with through slots 209, and the insulation layer of the cable 101 enters the rotating drum 205 through the through slot 209 on the left side and is tightly attached to the inner wall of the through slot 209 on the left side, and the conductor of the cable 101 exits through the through slot 209 on the right side.

[0019] Specifically, the outer wall of the rotating drum 205 is provided with a through groove 307 that extends to its inner wall; during the process of the cutting tool A201 chamfering the insulation layer of the cable 101, the cut insulation layer can fall into the through groove 307 along the gap between multiple inner lining plates 202, and thus fall to the outside of the rotating drum 205.

[0020] Specifically, the rotating drum 205 is provided with a trimming assembly to prevent unevenness of the insulation layer end face of the cable 101. The trimming assembly includes a cutter B208, which is slidably disposed in the inner liner 202 corresponding to it, and the cutter B208 has a cutting edge near the end and side of the cable 101.

[0021] Specifically, the end of the cutter B208 away from the cable 101 is rotatably connected to a bolt B207, and the bolt B207 is threadedly connected to the rotating drum 205, with the end of the bolt B207 passing through the rotating drum 205.

[0022] In the above embodiment, after the user fixes the conductor of the cable 101 with the arc block 305 and manually straightens the cable 101, the user can rotate the bolt B207, so that the blade of the cutter B208 is vertically inserted into the insulation layer of the cable 101 until the bolt B207 can no longer be rotated. At this time, the blade of the cutter B208 is in contact with the conductor of the cable 101. Then the cutter B208 can be rotated around the cable 101, so that the insulation layer of the cable 101 is cut by the blade on the side of the cutter B208 to ensure that the end face of the insulation layer of the cable 101 is smooth and flat, so as to avoid affecting the chamfering accuracy. Then the user can stop the two arc blocks 305 from clamping the cable 101 to remove the cut insulation layer and adjust the position of the end face of the insulation layer of the cable 101 to bring it close to the cutter A201 to facilitate chamfering.

[0023] Specifically, the frame 301 is provided with a drive assembly for making the rotating drum 205 rotate at a uniform speed. The drive assembly includes a gear ring 302, which is fixedly connected to the outer wall of the rotating drum 205. A gear 303 is meshed on the gear ring 302. The gear 303 is fixedly connected to the output shaft of the motor 304, and the motor 304 is fixedly connected to the frame 301.

[0024] In the above embodiment, the user can start the motor 304, so that the gear 303 fixedly connected to its output shaft starts to rotate at a constant speed. At this time, the drum 205 starts to rotate at a constant speed under the cooperation of the gear 303 and the gear ring 302, so that the drum 205 drives the cutter A201 and cutter B208 installed inside it to start rotating.

[0025] Specifically, the frame 301 is provided with a limiting structure for fixing the conductor of the cable 101. The limiting structure includes an arc block 305, two arc blocks 305 are symmetrically arranged, and the conductor of the cable 101 passes through the space between the two arc blocks 305.

[0026] Specifically, one of the arc blocks 305 is fixedly connected to the frame 301, and the other arc block 305 is fixedly connected to the output shaft of the cylinder 306, and the cylinder 306 is fixedly connected to the frame 301.

[0027] In the above embodiment, after the user passes the conductor of the cable 101 through the rotating cylinder 205 and places it between the two arc blocks 305, the user can start the cylinder 306, so that the cylinder 306 begins to push the arc block 305 fixedly connected to its output shaft, so that the two arc blocks 305 cooperate with each other to clamp the conductor of the cable 101, thereby fixing the end of the cable 101 and preventing the cable 101 from moving during the chamfering process.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0030] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0031] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0032] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0033] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
