Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cable cutting device. Background Technology

[0002] Armored cables typically consist of an inner core wire, a metal armor layer surrounding the inner core wire, and an insulation layer covering the metal armor layer.

[0003] The metal armor layer is typically a metal strip wrapping layer or a metal braided layer. When performing wiring work, it is usually necessary to cut the metal armor layer at the ends. Currently, wire cutters are mainly used to cut the metal armor layer, which can easily cut into the internal core wires, damaging or even severing the internal core wires within the metal armor layer.

[0004] Therefore, this utility model is dedicated to developing a cable cutting device that can cut the metal armor layer without damaging the internal core wire.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0050] See Figure 1 and Figure 2 This utility model provides a cable cutting device, comprising:

[0051] Push-slide assembly 1, the push-slide assembly 1 includes a push-slide base 101 and a push-slide slide plate 102 slidably disposed above the push-slide base 101 and used to fix the armored cable;

[0052] Connector fixing seat 2;

[0053] Connector assembly 3, which is rotatably mounted on connector fixing base 2;

[0054] Rotary hob 4, which is detachably connected to one end of the connector assembly 3;

[0055] The rotary drive assembly 5 is connected to the other end of the connector assembly 3. The connector assembly 3 drives the rotary cutter 4 to rotate to cut the metal armor layer 100 of the armored cable.

[0056] The cable cutting device provided in this embodiment operates as follows when it is necessary to cut the metal armor layer 100:

[0057] ① Place the stripped armored cable on the sliding plate 102;

[0058] ② Select a rotary cutter 4 of appropriate diameter according to the wire diameter of the armored cable;

[0059] ③ The rotary drive assembly 5 is started, and the rotary hob 4 is driven to rotate through the connector assembly 3;

[0060] ④ Push the sliding plate 102 to move the armored cable below the rotating cutter 4, then rotate the armored cable and the rotating cutter 4 will cut the metal armor layer 100.

[0061] Optionally, the diameter requirement for the rotary cutter 4 is: the lowest point of the rotary cutter 4 slightly exceeds the inner wall of the metal armor layer 100 so that the rotary cutter 4 can completely cut the metal armor layer 100.

[0062] Alternatively, the diameter requirement for the rotary cutter 4 is that the lowest point of the rotary cutter 4 just reaches or slightly exceeds the inner wall of the metal armor layer 100. After cutting, the metal armor layer 100 can be broken off by hand, and then the broken metal armor layer 100 can be removed.

[0063] Therefore, the cable cutting device provided by this utility model can cut the metal armor layer 100 without damaging the internal core wire.

[0064] In this embodiment, the push-slide plate 102 is provided with a cable receiving groove 1021 for accommodating the armored cable and a roller avoidance groove 1022 for avoiding the rotating roller 4 and perpendicular to the cable receiving groove 1021.

[0065] The bottom of the cable receiving groove 1021 is provided with several resistance-reducing rollers 6, and the rotation axis of the resistance-reducing rollers 6 is parallel to the length direction of the cable receiving groove 1021. The resistance-reducing rollers 6 can reduce the frictional resistance encountered by the armored cable when rotating in the cable receiving groove 1021, thereby improving the circumferential cutting efficiency of the metal armor layer 100.

[0066] Optionally, the sliding base 101 is equipped with a magnet 7, and the sliding plate 102 is equipped with an iron block 8. When the sliding plate 102 slides relative to the sliding base 101 to a position away from the rotating cutter 4, the iron block 8 faces the magnet 7 and is magnetically connected to the magnet 7. This prevents the sliding plate 102 from sliding randomly when no cutting operation is being performed, and also facilitates the positioning of the sliding plate 102 so that the armored cable can be placed into the cable receiving slot 1021.

[0067] In this embodiment, the connector assembly 3 includes a coupling 301 rotatably mounted on the connector mounting base 2, a transmission rod 302 connecting the coupling 301 and the rotary cutter 4, and a universal flexible shaft 303 connecting the drive end of the rotary drive assembly 5 to the coupling 301. Specifically, the rotary cutter 4 is fastened to the transmission rod 302 by fastening bolts 9, and the rotary cutter 4 can be replaced by loosening the fastening bolts 9.

[0068] Optionally, the connector fixing seat 2 is provided with a first receiving cavity 201 located below the coupling 301 and a second receiving cavity 202 located below the first receiving cavity 201. The rotary drive assembly 5 includes a rotary drive mechanism 501 located in the first receiving cavity 201 and a battery 502 located in the second receiving cavity 202 and electrically connected to the rotary drive mechanism 501. The coupling 301, rotary drive mechanism 501, and battery 502 are arranged from top to bottom, which helps to reduce the floor space and improve the structural compactness. The use of the universal flexible shaft 303 mainly ensures that even if the rotary drive mechanism 501 is located directly below the coupling 301, the rotary drive mechanism 501 can still be smoothly connected to the coupling 301 for transmission.

[0069] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.

[0070] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
