Description

Technical Field

[0001] This utility model relates to the technical field of cable cutting, specifically to a cable cutting machine. Background Technology

[0002] Factory-produced cables are typically shipped in fixed lengths (e.g., 100 meters, 300 meters, 1000 meters, several kilometers) wound on reels. When the total length of the laying path exceeds the length of a single reel, multiple reels must be connected. This requires cutting the end of the first reel to prepare for connecting the beginning of the next reel. Even if the total path length is less than the length of a single reel, the cable must be cut to the precise length required between the equipment ports to avoid tangling, redundancy, waste, or affecting aesthetics and safety. During construction, if partial cable damage is found, to ensure final performance and reliability, the segment containing the damaged point must be cut off and removed, using only the intact portion. The sections before and after the damaged point need to be cut, and then the intact portions reconnected using splices or connectors.

[0003] Cable manufacturers typically have cable cutting equipment inside their facilities for cutting cables during fixed-length winding. However, due to their large size and weight, these equipment is inconvenient to carry and use. Furthermore, when cutting cables on-site, ordinary hydraulic pliers are generally suitable for cutting cables with a diameter of less than 2cm. For cables with larger diameters, electric angle grinders are typically used due to site limitations, which pose significant safety risks. Chinese patent application CN202322489707.0, entitled "A Cable Cutter for Easy Unloading," discloses a cable cutter that facilitates unloading. Compared to existing technologies, its design, including a cutting table, shaft, connecting seat, cutter, and handle, allows for manual cable cutting, making it easier to adjust the cutting point for greater precision. The overall structure is simple, easy to operate, and portable, allowing for convenient use anytime, anywhere, particularly during cable installation and cutting. However, the above patent still has the following shortcomings. The cable cutter is small in size and easy to carry to the construction site for use. However, the cutter relies on manually pressing down the handle to cut the cable. The shearing force applied to the cable by hand is limited. It is difficult to use manually when cutting cables with a diameter greater than 2cm. It cannot cut cables with a diameter greater than 4cm. Therefore, it is necessary to design a cable cutting machine. Utility Model Content

[0006] Preferably, the mounting mechanism includes a connector fixedly connected to the first guide rod. The side of the connector away from the electric push rod is recessed with a strip-shaped groove that matches the cutter. At least one mounting bolt passing through the strip-shaped groove is threaded onto the connector. The cutter has a positioning hole through which the mounting bolt passes.

[0007] Preferably, a guide sleeve is fixedly fitted to one end of the first mounting bracket near the fixed half ring. The guide sleeve is provided with at least one circular through groove and an arc-shaped through groove whose axis is parallel to the axis of the circular through groove and is provided with a first notch.

[0008] The first guide rod slides through the corresponding circular through groove. A second guide rod is fixedly connected to the connector, which slides through the arc-shaped through groove and is fixedly connected to the first guide rod. A rack of the same length is fixedly connected to the second guide rod, which is directly opposite the first notch. A transmission mechanism connected to the rack is mounted on the first mounting bracket. A motor connected to the transmission mechanism is detachably mounted on the first mounting bracket via a second mounting bracket.

[0009] Preferably, the transmission mechanism includes a connecting shaft mounted on a first mounting bracket via a pair of bearing seats and disposed near a fixed half-ring, and a gear fixedly sleeved on the connecting shaft and meshing with a rack. The output shaft of the motor is connected to one end of the connecting shaft via a coupling.

[0010] Preferably, the ends of the first guide rod and the second guide rod away from the fixed semi-ring are fixedly connected by a connecting frame, and the output end of the electric push rod is detachably connected to the connecting frame.

[0011] Preferably, the fixed half-ring includes a pair of first half-ring pieces spaced apart, a support sleeve is provided between the pair of first half-ring pieces, the movable half-ring protects a pair of second half-ring pieces spaced apart and respectively in contact with the outer walls of the pair of first half-ring pieces, the first hinge bolt passes through the pair of first half-ring pieces, the pair of second half-ring pieces and the support sleeve, and the cutter is located between the pair of first half-ring pieces.

[0013] The first connecting seat has a protruding part that matches the threaded rod. The protruding part has a second notch for receiving the threaded rod. The opening end of the second notch is provided with a limiting flange on the side away from the second connecting seat.

[0014] Preferably, the outer wall of the rotating sleeve is provided with anti-slip texture.

[0015] According to the above technical solution, the cable cutting machine provided by this utility model has the following beneficial effects during use:

[0016] Firstly, by placing the movable half-ring and the fixed half-ring on the cable, the electric push rod drives the cutter to move closer to the cable through the first guide rod, thus cutting the cable.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-4 As shown, a cable cutting machine includes: a fixed half-ring 1, a movable half-ring 3 connected to one end of the fixed half-ring 1 via a first hinge bolt 2, a first mounting bracket 4 mounted on the fixed half-ring 1, at least one first guide rod 5 slidably connected to the first mounting bracket 4 and slidable toward the center of the fixed half-ring 1, a cutter 6 detachably mounted on the first guide rod 5 near the center of the fixed half-ring 1 via a mounting mechanism, and an electric push rod 7 detachably mounted on the first mounting bracket 4 and separably connected to the end of the first guide rod 5 away from the cutter 6. The end of the movable half-ring 3 away from the first hinge bolt 2 is separably connected to the fixed half-ring 1 via a quick-release mechanism.

[0031] In the above technical solution, when in use, the quick-release mechanism is disassembled, the movable half-ring 3 is rotated, and the movable half-ring 3 and the fixed half-ring 1 are placed on the cable. Then, the end of the movable half-ring 3 away from the first hinge bolt 2 is connected to the fixed half-ring 1 through the quick-release mechanism. Then, the electric push rod 7 drives the cutter 6 to move closer to the cable through the first guide rod 5. The cutter 6 first pushes the cable so that the cable comes into contact with the movable half-ring 3. As the cutter 6 continues to move, the cable can be cut. As long as the diameter of the cable is smaller than the inner diameter of the fixed half-ring 1, it can be cut. It has a wide range of applications.

[0032] One end of the movable half-ring 3 is connected to the fixed half-ring 1 via the first hinge bolt 2, and the other end is connected to the fixed half-ring 1 via a quick-release mechanism. During the cable cutting process, tension can be applied to both ends of the movable half-ring 3 to improve the pressure resistance of the movable half-ring 3 during use. At the same time, the cable is confined to the inside of the fixed half-ring 1 and the movable half-ring 3, so that the cable is within the cutting range of the cutter 6, making it convenient to use.

[0033] The electric linear actuator 7 can be replaced according to actual usage needs. It can be replaced with a pneumatic cylinder, a hydraulic cylinder, or other common linear drive devices, and can be replaced on-site according to existing equipment. Compared with pneumatic cylinders and hydraulic cylinders, the electric linear actuator 7 can be used simply by plugging it in, without the need for other auxiliary equipment, making it convenient to use and easy to carry.

[0034] In a preferred embodiment of the present invention, the mounting mechanism includes a connector 8 fixedly connected to the first guide rod 5. The connector 8 has a recessed slot on the side away from the electric push rod 7 that matches the cutter 6. At least one mounting bolt 9 is threaded onto the connector 8 and passes through the slot. The cutter 6 has a positioning hole through which the mounting bolt 9 passes.

[0035] In the above technical solution, when the cutter 6 needs to be replaced, loosen and remove the mounting bolt 9, take the cutter 6 out of the strip slot, insert one side of the new cutter 6 into the strip slot, and then assemble the mounting bolt 9. The mounting bolt 9 will pass through the corresponding positioning hole, thereby fixing the cutter 6. The operation of replacing the cutter 6 is simple, and the replaced cutter 6 can be reused after being polished.

[0036] In a preferred embodiment of the present invention, a guide sleeve 10 is fixedly fitted to one end of the first mounting bracket 4 near the fixed half ring 1. The guide sleeve 10 is provided with at least one circular through groove and an arc-shaped through groove whose axis is parallel to the axis of the circular through groove and is provided with a first notch.

[0037] The first guide rod 5 slides through the corresponding circular through groove. The connector 8 is fixedly connected to a second guide rod 11 that slides through the arc-shaped through groove and is fixedly connected to the first guide rod 5. The second guide rod 11 is fixedly connected to a rack 12 of the same length that is directly opposite the first notch. The first mounting bracket 4 is equipped with a transmission mechanism that is driven by the rack 12. The first mounting bracket 4 is detachably equipped with a motor 13 that is connected to the transmission mechanism through a second mounting bracket.

[0038] In the above technical solution, only one of the electric push rod 7 and motor 13 exists on the first mounting bracket 4 at the same time. The choice can be made according to the existing conditions of the site. Two driving methods are available for the user to choose from: linear drive or rotary drive.

[0039] When the motor 13 is assembled on the first mounting bracket 4, the output shaft of the motor 13 is connected to the transmission mechanism. The output shaft of the motor 13 is connected to the rack 12 through the transmission mechanism, thereby driving the second guide rod 11 to slide along its own length direction, driving the cutter 6 to move. During the movement, the rack 12 will pass through the first notch.

[0040] In a preferred embodiment of the present invention, the transmission mechanism includes a connecting shaft 14 mounted on a first mounting bracket 4 via a pair of bearing seats and disposed near the fixed half-ring 1, and a gear 15 fixedly sleeved on the connecting shaft 14 and meshing with a rack 12. The output shaft of the motor 13 is connected to one end of the connecting shaft 14 via a coupling.

[0041] In the above technical solution, the output shaft of the motor 13 drives the connecting shaft 14 to rotate through the coupling, thereby driving the gear 15 to rotate, and then the gear 15 drives the rack 12 to move.

[0042] In a preferred embodiment of the present invention, the ends of the first guide rod 5 and the second guide rod 11 away from the fixed half ring 1 are fixedly connected by a connecting frame 16, and the output end of the electric push rod 7 is detachably connected to the connecting frame 16.

[0043] In a preferred embodiment of the present invention, the fixed semi-ring 1 includes a pair of first semi-ring pieces spaced apart, a support sleeve 17 is provided between the pair of first semi-ring pieces, the movable semi-ring 3 protects a pair of second semi-ring pieces spaced apart and respectively in contact with the outer walls of the pair of first semi-ring pieces, the first hinge bolt 2 passes through the pair of first semi-ring pieces, the pair of second semi-ring pieces and the support sleeve 17, and the cutter 6 is located between the pair of first semi-ring pieces.

[0044] In the above technical solution, the cutter 6 is located between a pair of first semi-circular pieces, which can protect the cutter 6. When it is in the storage state, the blade of the cutter 6 is located between a pair of first semi-circular pieces, which can protect the blade of the cutter 6 and also prevent accidental injury to others.

[0045] During use, the cutter 6 will first push the cable close to the movable ring until the cable touches the movable ring. Both of the second half rings can provide support for the cable, and the cutter 6 is located in the middle, which can prevent the cable from being skewed due to shearing force during the cutting process.

[0046] In a preferred embodiment of the present invention, the quick-release mechanism includes a first connecting seat 18 fixedly connected to the end of the fixed half-ring 1 away from the first hinge bolt 2, a second connecting seat 19 fixedly connected to the end of the movable half-ring 3 away from the first hinge bolt 2, a threaded rod 20 rotatably connected to the second connecting seat 19 via the second hinge bolt, and a rotating sleeve 21 threadedly rotatably sleeved on the threaded rod 20.

[0047] The first connecting seat 18 has a protruding part that matches the threaded rod 20. The protruding part has a second notch for the threaded rod 20 to be accommodated. The opening end of the second notch is provided with a limiting flange 22 on the side away from the second connecting seat 19.

[0048] In the above technical solution, rotating the movable half ring 3 causes the second connecting seat 19 to contact the first connecting seat 18, rotating the threaded rod 20 so that it is located inside the second notch, and tightening the rotating sleeve 21 so that it tightly abuts against the side of the protrusion away from the second connecting seat 19, thereby fixing the first connecting seat 18 and the second connecting seat 19 together; loosening the rotating sleeve 21 to separate it from the protrusion, rotating the threaded rod 20 to move it out of the second notch, can then rotate the movable half ring 3.

[0049] In a preferred embodiment of this utility model, the outer wall of the rotating sleeve 21 is provided with anti-slip texture.

[0050] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction.
