Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a fixed-distance cutting device for railway cable processing. Background Art

[0002] Railway cable processing and cutting equipment is critical for ensuring stable railway communications and power transmission. It typically consists of a cutting tool, a drive system, and a cable fixing assembly. The drive system provides power, driving the sharp cutting tool to precisely cut various types of railway cables. The cable fixing assembly prevents the cable from shaking during cutting, ensuring a smooth cut. Some advanced devices also feature length measurement and automatic counting functions, enabling precise cutting of cables as needed and counting the number of cables processed, greatly improving the efficiency and accuracy of railway cable processing. However, existing railway cable processing and cutting equipment still presents certain challenges when used:

[0003] For example, a cutting device for household cable processing with application number 202211198364.6 has the following technical solution: it includes a cutting table, an L-shaped frame is fixedly connected to the back of the cutting table, a cylinder is fixedly connected to the top of the L-shaped frame, the output end of the cylinder is fixedly connected to a fixed frame, and a cutting knife is installed on the inner wall of the fixed frame. The present invention can prevent people from touching the surface of the cutting knife and causing damage when cutting the cable, so that the cable can be completely fixed when cutting to prevent it from shaking, and the outer layer of the cable can be stripped and separated at the same time. However, the existing cutting device for cable processing lacks a fixed-distance cutting function, and the operator needs to manually measure and mark the cable length, which is not only inefficient, but also has large manual measurement errors, resulting in inconsistent cable lengths after cutting, affecting the subsequent assembly and use of the railway. At the same time, the existing device is difficult to adjust the cutting length and can only cope with cables of a single specification. When encountering railway cables of different thicknesses, it cannot be flexibly adapted.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case.

[0005] In response to the above problems, an innovative design was carried out based on the original railway cable processing and cutting device. Utility Model Content

[0037] Working principle:

[0038] When the present invention is in use, the cable specification is limited to railway cables with smaller diameters. First, the railway cable is passed through the cable hole 2 on the right side of the support frame 1, and one end of the cable is connected to the transport device, and the speed of the transport device transmitting the cable needs to be set to be faster, so that the one-time cutting can be completed according to the cutting process; according to the required cutting length, the turning handle 5 is rotated, and the turning handle 5 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the moving block 7 to move left and right in the first slide block 4, adjusts the position of the moving block 7, and flexibly installs the turning plate 8 in the required limiting hole 10. When the railway cable is transported to the left, it touches the turning plate 8 and drives it to rotate. The turning plate 8 moves in the limiting hole 10 and drives the limiting plate 9 to move to the right synchronously. The straight rack 11 on the right side of the limiting plate 9 moves with the limiting plate 9, and the straight rack 11 is engaged with the transmission gear 13, so that the transmission gear As the wheel 13 rotates, the first bevel gear 14 below the transmission gear 13 rotates accordingly, and the first bevel gear 14 meshes with the second bevel gear 15, driving the second bevel gear 15 to rotate. The first gear 16 on the right side of the second bevel gear 15 rotates accordingly, and the first gear 16 meshes with the second gear 17, causing the second gear 17 to rotate. The limiting column 18 on the right side of the first gear 16 and the second gear 17 slides in the first hole groove 20 of the connecting rod 19, driving the connecting rod 19 to move, and the cutting tool 22 sleeved in the second hole groove 21 at the front end of the connecting rod 19 slides in the second slide block 23, and the cutting tool 22 moves toward each other to cut the railway cable.

The above operation is repeated to achieve continuous fixed-distance cutting.
