Description

Technical Field

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

[0002] In the large-scale production and post-processing of wires and cables, cutting is one of the core processes to ensure product specification consistency and adaptability to downstream application scenarios. With the continuous growth in demand for cables from the power, communication, and rail transportation sectors, as well as the iterative upgrades of new products such as new energy cables and high-temperature resistant special cables, the market is placing increasingly stringent requirements on the processing efficiency, adaptability, and ease of maintenance of cutting equipment. Among these, the cutting blades, as a core loss component that directly impacts the cable, have their replacement efficiency directly affecting the downtime and processing costs of the entire production line, becoming a key factor restricting the overall performance of the equipment.

[0003] Most existing wire and cable cutting devices use traditional bolt or welding methods for blade mounting. Since different specifications and materials of cables have different requirements for the blade's cutting angle, hardness, and size, traditional fixing structures cannot achieve rapid blade switching. When the production line needs to adapt to multiple cable products, multiple dedicated cutting devices are required, which increases equipment investment and occupies a lot of workshop space.

[0004] Therefore, it is necessary to provide a new cutting device for wire and cable processing to solve the above-mentioned technical problems. Utility Model Content

[0019] The telescopic cylinder 4 is activated to drive the push-pull shaft 401, which in turn moves the linkage convex plate 402 toward the outside of the cutting housing 3. Then, the cutting housing 3 drives the two linkage shafts 403 to squeeze the two cutting seats 5 along the two linkage grooves 501 and rotate them close to each other with the two connecting shafts 502 as the axis. As a result, the two cutting seats 5 drive the two cutting blades 6 to cut the wires and cables. The above operation is then performed in reverse so that the two cutting seats 5 drive the two cutting blades 6 to rotate apart, which facilitates the cutting of the next section of wires and cables.

[0020] In the specific implementation process, such as Figure 3-6As shown, the limiting assembly includes a support frame plate 7, a spring rod 701, a return spring 703, and a trapezoidal locking block 704. The support frame plate 7 is fixedly connected to the outside of one of the cutting seats 5. A locking block groove 503 is provided on one side of the cutting seat 5, and the locking block groove 503 is connected to the blade groove 504. The trapezoidal locking block 704 is slidably connected between the locking block groove 503 and the blade groove 504. The end of the trapezoidal locking block 704 away from the locking block groove 503 is fixedly connected to the spring rod 701. The spring rod 701 extends through to the outside of the support frame plate 7. The return spring 703 is sleeved on the outer surface of the spring rod 701 and is located between the support frame plate 7 and the trapezoidal locking block 704. Preferably, the docking assembly includes a push-pull rod 601, a sliding ring 602, a conical guide block 603, a semi-circular locking block 604, and a fixed ring 605. The cutting blade 6 has a push-pull rod groove 606 and a limiting groove inside. 607. The push-pull rod slide groove 606 is connected to the limiting groove 607. The inner wall of the push-pull rod slide groove 606 is provided with a fixing ring 605. The push-pull rod 601 is slidably connected inside the push-pull rod slide groove 606. The push-pull rod 601 is slidably connected inside the fixing ring 605. A sliding ring 602 is sleeved on the outer surface of the push-pull rod 601. The sliding ring 602 is slidably connected inside the limiting groove 607. The push-pull rod slide groove 606 extends to the outside of the push-pull rod slide groove 606. A tapered guide block 603 is slidably fitted on the outer surface of the cutting shell 601 and a semi-circular locking block 604 is fixedly connected to its end face. A circular baffle 608 is fitted on the outer surface of the push-pull rod 601. The circular baffle 608 is located between the tapered guide block 603 and the cutting blade 6. The end of the semi-circular locking block 604 near the push-pull rod 601 is in contact with the tapered guide block 603. A limiting plate 702 is fitted on the outer surface of the spring rod 701. The wire and cable body 2 is slidably connected inside the cutting shell 1.

[0021] The working principle of this utility model is as follows: When different cutting blades need to be replaced, the operator pushes the push-pull rod 601 to slide towards the blade slide groove 504. Then, the push-pull rod 601 pushes the conical guide block 603 to contact the inclined surface of the trapezoidal locking block 704 and squeezes the trapezoidal locking block 704 to slide along the locking block slide groove 506 towards the outside of the cutting seat 5. Then, the trapezoidal locking block 704 squeezes the return spring 703. When the conical guide block 603 passes the trapezoidal locking block 704, the return spring 703 drives the trapezoidal locking block 704 to return to its original position. At this time, the conical guide block 603 is in contact with the semi-circular locking block 604. Then, the operator pulls the push-pull rod 601 outward. The tapered guide block 603 presses the trapezoidal locking block 704 with its inclined surface to compress the return spring 703. Then, the push-pull rod 601 drives the tapered guide block 603 and the semi-circular locking block 604 to pass over the trapezoidal locking block 704, thereby releasing the locking between the cutting blade 6 and the cutting seat 5. Then, the new cutting blade 6 slides along the blade groove 504 and connects to the inside of the cutting seat 5. Then, the new cutting blade 6 drives the semi-circular locking block 604 to enter the inside of the blade groove 504 and abut against the inclined end of the trapezoidal locking block 704 through the push-pull rod 601. Then, the semi-circular locking block 604 passes over the trapezoidal locking block 704, so that the trapezoidal locking block 704 limits the semi-circular locking block 604.
