Description

An automatic cable cutting machine for producing cables of varying lengths. Technical Field

[0001] This utility model belongs to the technical field of cable production equipment, and in particular relates to an automatic cable cutting machine for cutting cable length. Background Technology

[0002] In the cable manufacturing process, cable cutting is a crucial link between upstream and downstream processes. Its quality and efficiency directly affect the subsequent processing, packaging, and application of cables. Currently, there are many types of cable cutting equipment on the market, but they all have varying degrees of defects.

[0003] During cable cutting, not only must precise length cutting be achieved, but the treatment of the cable sheath must also be considered. Some traditional cutting equipment cannot simultaneously meet the requirements of breaking the cable sheath and precise cutting, which leads to the need for additional processes to treat the sheath in subsequent cable processing, increasing production and time costs.

[0004] To address these issues, we provide an automatic cable cutting machine that cuts cables to the required lengths. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cable cutting machine for cutting cable length. By cooperating with the cutting mechanism and the positioning mechanism, it solves the problem that the cutting equipment in the prior art cannot simultaneously meet the requirements of breaking the cable sheath and cutting it accurately, which leads to the need for additional processes to deal with the sheath in the subsequent cable processing.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an automatic cable cutting machine for cutting cable lengths, comprising a base shell, a cutting mechanism fixedly connected to the top of the base shell, a fixed base fixedly connected to the bottom front end of the base shell, and a positioning mechanism fixedly connected to the top of the fixed base. The cutting mechanism includes a housing, which is disposed above the base shell. Electric push rods are fixedly connected to both sides of the top of the base shell, and the tops of the electric push rods are fixedly connected to the housing. A cylinder is fixedly connected to the top of the housing, and the bottom of the cylinder penetrates the housing into the inner cavity and is fixedly connected to a mounting plate. A fixing frame is fixedly connected to one side of the bottom of the mounting plate, and a first cutting blade is fixedly connected to the bottom of the fixing frame. A connecting frame is fixedly connected to the other side of the bottom of the mounting plate, and a first insulation-breaking blade is movably connected to the bottom of the connecting frame via a rotating shaft. A mounting base is fixedly connected to one side of the inner cavity of the base shell, and the top of the mounting base is fixedly... A second cutting blade is fixedly connected to the bottom shell cavity, and a second sheath-breaking blade is movably connected to the other side of the bottom shell cavity. The second cutting blade has the same structure as the first cutting blade. When used together, they can cut the cable from both top and bottom directions simultaneously, ensuring the stability and accuracy of the cut. The second sheath-breaking blade is movably connected to the other side of the bottom shell cavity. The structure of the second sheath-breaking blade is the same as the first sheath-breaking blade. It can work together with the first sheath-breaking blade to achieve double-sided sheath breaking of the cable sheath. The electric push rod can separate the outer shell from the bottom shell, so that the cutting area and waste residue inside the bottom shell are fully exposed. This makes it convenient for operators to quickly clean up debris, residual cable sheath, and other debris generated during the cutting process, greatly reducing the difficulty of cleaning, improving the maintenance efficiency of the equipment, avoiding the impact of waste accumulation on equipment performance and subsequent production, and ensuring that the equipment is always in good operating condition.

[0008] The present invention is further configured such that the positioning mechanism includes a support frame, the bottom of the support frame is fixedly connected to a fixed seat, the top of the support frame is threadedly connected to a threaded rod, the bottom of the threaded rod is movably connected to a first clamping plate through a bearing, and the top two sides of the fixed seat are fixedly connected to second clamping plates. By rotating the threaded rod, the height of the first clamping plate can be changed to adapt to the clamping requirements of cables of different diameters. There is no need for complicated disassembly and installation processes, which greatly improves the applicability of the equipment to cables of different specifications. The second clamping plate and the first clamping plate form a three-point clamping layout, which effectively restricts the movement of the cable in the horizontal direction.

[0009] The present invention is further configured such that a handwheel is fixedly connected to the top of the threaded rod, and the surface of the handwheel is provided with anti-slip texture. When the handwheel is rotated to adjust the height of the first clamping plate, the friction between the hand and the handwheel can be effectively increased. This not only makes the operation process more labor-saving, but also avoids misoperation caused by hand slippage.

[0010] The present invention is further configured such that limit posts are fixedly connected to the four corners of the bottom of the outer shell, and limit holes are provided at the four corners of the top of the bottom shell to cooperate with the limit posts. The limit posts and limit holes play a guiding and limiting role during the lifting and lowering of the outer shell. Since the diameter of the limit hole is slightly larger than the diameter of the limit post, a clearance fit is adopted, which allows the outer shell to be lifted and lowered smoothly under the drive of the electric push rod, and effectively limits the horizontal displacement and sway of the outer shell.

[0011] The present invention is further configured such that a sliding groove is provided on one side of the inner cavity of the support frame, and one side of the sliding groove is slidably connected to the first clamping plate. The sliding groove cooperates with the slider integrally formed on the side of the first clamping plate to provide stable guidance for the up and down movement of the first clamping plate.

[0012] The present invention is further configured such that a first arc-shaped groove is provided on both sides of the bottom shell surface, and a second arc-shaped groove is provided on both sides of the outer shell surface to cooperate with the first arc-shaped groove. When the outer shell is lowered to the working position, they are connected to each other to form a complete arc-shaped channel. The curvature of the arc-shaped channel matches the outer contour of the cable, which can further limit and guide the cable from the side.

[0013] The present invention is further configured such that a fixing plate is fixedly connected to the surface of the cylinder, and the bottom of the fixing plate is fixedly connected to the outer shell by fasteners. The fixing plate is firmly connected to the outer shell by fasteners, which greatly enhances the connection strength between the cylinder and the outer shell.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model controls the descent height and force of the first and second cutting blades with a cylinder, and combines the positioning mechanism to firmly clamp the cable, thereby achieving precise cutting of the cable. At the same time, the synchronous setting of the first and second sheath-removing blades can completely remove the outer sheath of the cable without additional procedures. This ensures the accuracy of the cutting length and meets the needs of subsequent cable processing for sheath removal, significantly improving production efficiency and reducing overall costs.

[0016] 2. This utility model allows the operator to quickly adjust the height of the first clamping plate by rotating the handwheel to drive the threaded rod, adapting to the clamping requirements of cables of different diameters. The anti-slip texture design on the handwheel surface ensures stable and labor-saving operation. The sliding cooperation between the support frame, the slide groove and the first clamping plate, as well as the auxiliary positioning of the second clamping plate, form a multi-dimensional and stable clamping structure, keeping the cable in a fixed state during the cutting process. This effectively avoids cutting deviations caused by cable displacement, improving cutting accuracy and yield. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please refer to Figures 1-5. This utility model is an automatic cable cutting machine for cutting cable lengths. It includes a base shell 1, a cutting mechanism 2 fixedly connected to the top of the base shell 1, a fixed base 3 fixedly connected to the bottom front end of the base shell 1, and a positioning mechanism 4 fixedly connected to the top of the fixed base 3. The cutting mechanism 2 includes a housing 21, which is located above the base shell 1. Electric push rods 22 are fixedly connected to both sides of the top of the base shell 1. The top of the electric push rods 22 is fixedly connected to the housing 21. A cylinder 23 is fixedly connected to the top of the housing 21. 3. The bottom extends through to the inner cavity of the outer shell 21 and is fixedly connected to a mounting plate 24. A fixing bracket 25 is fixedly connected to one side of the bottom of the mounting plate 24. A first cutting blade 26 is fixedly connected to the bottom of the fixing bracket 25. A connecting bracket 27 is fixedly connected to the other side of the bottom of the mounting plate 24. A first skin-breaking blade 28 is movably connected to the bottom of the connecting bracket 27 via a pivot. A mounting base 29 is fixedly connected to one side of the inner cavity of the bottom shell 1. A second cutting blade 210 is fixedly connected to the top of the mounting base 29. A second skin-breaking blade 211 is movably connected to the other side of the inner cavity of the bottom shell 1.

[0027] Specifically: The second cutting blade 210 works in conjunction with the first cutting blade 26 to cut the cable simultaneously from both above and below, ensuring the stability and accuracy of the cut. A second sheath-breaking blade 211 is movably connected to the other side of the inner cavity of the bottom shell 1. The structure of the second sheath-breaking blade 211 is the same as that of the first sheath-breaking blade 28, and it can work in conjunction with the first sheath-breaking blade 28 to achieve double-sided sheath breaking of the cable sheath. The electric push rod 22 can separate the outer shell 21 from the bottom shell 1, so that the cutting area and waste residue inside the bottom shell 1 are fully exposed, which makes it convenient for operators to quickly clean up debris, residual cable sheath and other debris generated during the cutting process, greatly reducing the difficulty of cleaning, improving the maintenance efficiency of the equipment, avoiding the impact of waste accumulation on equipment performance and subsequent production, and ensuring that the equipment is always in good operating condition.

[0028] Example 2

[0029] Please refer to Figures 1-5. Based on Embodiment 1, the positioning mechanism 4 includes a support frame 41. The bottom of the support frame 41 is fixedly connected to the fixed seat 3. A threaded rod 42 is threadedly connected to the top of the support frame 41. A first clamping plate 43 is movably connected to the bottom of the threaded rod 42 through a bearing. A second clamping plate 44 is fixedly connected to both sides of the top of the fixed seat 3. A handwheel 5 is fixedly connected to the top of the threaded rod 42. The surface of the handwheel 5 is provided with anti-slip texture. Limiting posts 6 are fixedly connected to the four corners of the bottom of the outer shell 21. Limiting holes that cooperate with the limiting posts 6 are opened at the four corners of the top of the bottom shell 1. A sliding groove 7 is opened on one side of the inner cavity of the support frame 41. One side of the sliding groove 7 is slidably connected to the first clamping plate 43. A first arc-shaped groove is opened on both sides of the surface of the bottom shell 1. A second arc-shaped groove that cooperates with the first arc-shaped groove is opened on both sides of the surface of the outer shell 21. A fixing plate 8 is fixedly connected to the surface of the cylinder 23. The bottom of the fixing plate 8 is fixedly connected to the outer shell 21 through fasteners.

[0030] Specifically: By rotating the threaded rod 42, the height of the first clamping plate 43 can be changed to accommodate the clamping needs of cables with different diameters, eliminating the need for complex disassembly and installation processes and significantly improving the equipment's applicability to cables of different specifications. The second clamping plate 44 and the first clamping plate 43 form a three-point clamping layout, effectively restricting the horizontal movement of the cable. When rotating the handwheel 5 to adjust the height of the first clamping plate 43, the friction between the hand and the handwheel 5 is effectively increased, making the operation more effortless and preventing misoperation caused by hand slippage. The limiting post 6 and the limiting hole play a guiding and limiting role during the lifting and lowering of the outer shell 21. Due to the slightly larger diameter of the limiting hole... The diameter of the limiting post 6 is fitted with a clearance, which allows the housing 21 to rise and fall smoothly under the drive of the electric push rod 22, while effectively limiting the horizontal offset and sway of the housing 21. The slide groove 7 cooperates with the slider integrally formed on the side of the first clamping plate 43, providing a stable guide for the up and down movement of the first clamping plate 43. When the housing 21 descends to the working position, they dock with each other to form a complete arc-shaped channel. The curvature of the arc-shaped channel matches the outer contour of the cable, which can further limit and guide the cable from the side. The fixing plate 8 is firmly connected to the housing 21 by fasteners, which greatly enhances the connection strength between the cylinder 23 and the housing 21.

[0031] The working principle of this utility model is as follows: the cable to be cut is placed above the fixed base 3, and the operator rotates the handwheel 5. The handwheel 5 drives the threaded rod 42 to rotate. When the threaded rod 42 rotates, the first clamping plate 43 moves vertically up and down along the slide groove 7. According to the cable diameter, the first clamping plate 43 is adjusted to a suitable height so that it cooperates with the second clamping plate 44 fixedly connected on both sides to form a three-point clamping layout and complete the effective positioning.

[0032] When cable cutting and sheathing operations are required, the piston rod of cylinder 23 extends downward, causing the mounting plate 24 to move downward. The first cutting blade 26 and the first sheathing blade 28 then descend. Driven by the mounting plate 24, the first cutting blade 26 moves downward and cooperates with the second cutting blade 210 to cut the cable simultaneously from both above and below, ensuring a stable and accurate cutting process. The first sheathing blade 28 and the second sheathing blade 211 have the same structure. During the descent, the first sheathing blade 28 and the second sheathing blade 211 cooperate to achieve double-sided sheathing of the cable. Cylinder 23 provides a stable thrust, ensuring that the blades can quickly and effectively complete the cutting and sheathing operations.

[0033] After a certain number of cable cutting operations are completed, the electric push rod 22 is activated. The electric push rod 22 drives the outer casing 21 to move upward and separate from the bottom casing 1. The cutting area and waste residue inside the bottom casing 1 are fully exposed, which makes it convenient for operators to quickly clean up debris, residual cable sheath and other debris generated during the cutting process, reduce the impact of waste accumulation on equipment performance, improve equipment maintenance efficiency, and prepare for the next cable cutting operation.

[0034] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
