Description

Technical Field

[0001] This utility model belongs to the technical field of cable processing equipment, specifically relating to a cable conductor fixed-length cutting device and system. Background Technology

[0002] In the manufacturing process of wires and cables, to ensure that the quality of the produced cables meets relevant requirements, the diameter of the conductor is usually controlled within a certain range. Commonly used diameter measuring equipment includes diameter gauges and micrometers. Diameter gauges are expensive and only suitable for measuring single wires. Using a micrometer to measure the conductor diameter has significant drawbacks: the measurement results are greatly affected by factors such as operator technique (e.g., clamping force) and the choice of measurement point (e.g., curved or straight sections), resulting in diameter measurement data fluctuations as high as ±0.005mm, and human error is uncontrollable. Currently, to avoid interference from conductor geometry and improve the accuracy of conductor diameter measurement, the "weight per meter" (i.e., the weight of 1 meter of copper conductor) is used to inversely calculate the cross-sectional area of ​​the cable conductor (cross-sectional area = weight per meter / (conductor density * conductor length)). The conductor diameter can then be calculated from the cross-sectional area, thus linking the conductor's specifications (diameter), weight, and length. By measuring the "weight per meter," the quality control of the semi-finished products can be achieved. This method offers strong objectivity, eliminating the influence of human measurement techniques on the diameter measurement structure, and the results are traceable and reproducible. When measuring the "weight per meter" of a conductor, it is necessary to cut the conductor to a fixed length. Existing methods involve measuring the cable conductor with a meter stick according to the required length, and then cutting it with scissors. This method suffers from technical problems such as inconvenience for single-person operation, inaccurate cutting length, and low repeatability, and is unsuitable for batch cutting of cable conductors. Utility Model Content

[0003] In view of the existing technical problems, this utility model aims to provide a cable conductor fixed-length cutting device and system, which can solve the technical problems of inconvenience for single-person operation and low cutting repeatability in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cable conductor length-cutting device is characterized by the following structure: it includes a base, at least two cutting blades, at least three clamping assemblies, and a length measuring ruler. The length measuring ruler is disposed on the upper surface of the base along its length direction. The number of clamping assemblies is at least one more than the number of cutting blades. Each clamping assembly has a first mounting seat at its bottom, which is fixedly connected to the base, and the fixed position of the first mounting seat on the base is adjustable along the width direction of the base. Each cutting blade has a second mounting seat at its bottom, which is fixedly connected to the base, and the fixed position of the second mounting seat on the base is adjustable along the length direction of the base. The multiple clamping assemblies are spaced apart along the length direction of the base, and the cutting blades are disposed between two adjacent clamping assemblies. Each clamping assembly has a vertically movable clamping part, which forms a clamping space for fixing the cable conductor between the clamping part and the first mounting seat.

[0006] The cutting blades can be existing commercially available products, such as large guillotines specifically for cutting wires and cables. When using the cable conductor length-cutting device of this application, adjust the longitudinal position of each clamping component on the base so that the clamping parts on the clamping components are on the same straight line, and this straight line is parallel to the line of the length measuring ruler. Adjust the lateral position of the cutting blades on the base according to the required cutting length so that the distance between two adjacent cutting blades is equal to the required cutting length. Open the cutting blades, place the cable conductor to be cut between the clamping part and the first mounting base along the length direction of the base, operate the clamping component at the end so that one end of the cable conductor is clamped and fixed by the clamping part, straighten the cable conductor so that the cable conductor is parallel to the line of the length measuring ruler. Operate each clamping component in sequence so that the cable conductor is clamped and fixed by the clamping part in sequence. Operate the cutting blades in sequence to cut the cable conductor to the required cutting length. By setting multiple clamping components and cutting blades, the cable conductor can be cut into multiple segments according to the required cutting length, and multiple cable conductors can be cut simultaneously. This utility model relates to a cable conductor fixed-length cutting device, which is convenient for single-person operation, simple to operate, and safe. This cable conductor fixed-length cutting device can quickly and stably cut the required length with high cutting repeatability.

[0007] Preferably, the clamping assembly includes a clamping part, a handle, a first link, a second link, a third link, and a fourth link, the two ends of the first link, the second link, the third link, and the fourth link are sequentially hinged to form a four-bar linkage; the handle is fixedly connected to the first link, the clamping part is fixedly connected to the third link, and the bottom of the fourth link is fixedly connected to the first mounting base; when the handle is pushed upward, the clamping part moves downward to fix the cable conductor disposed in the clamping space.

[0008] Specifically, the clamping part includes a connecting rod and a rubber block. The upper end of the connecting rod is fixedly connected to the third connecting rod, and the lower end of the connecting rod is fixedly connected to the rubber block.

[0010] Specifically, the upper end of the connecting rod is threaded, and the connecting rod is locked and fixed to the first oblong mounting hole by a nut. The threaded design facilitates the fixing of the connecting rod and also allows for adjustment of its vertical position.

[0011] Preferably, each of the second mounting bases is provided with two limiting rods, which are respectively located on the left and right sides of the cutter. When the clamping part of the clamping assembly clamps and fixes the cable conductor, the cable conductor is in a straight line, and the side walls of the limiting rods on both sides of the cutter abut against the cable conductor. By setting the limiting rods, the cable conductors on the left and right sides of the cutter are limited, reducing the deviation of the cable conductor.

[0012] Preferably, the lower end of the limiting rod is fixedly connected to the second mounting base, and the fixed position of the lower end of the limiting rod on the second mounting base can be adjusted along the width direction of the base. The setting position of the limiting rod is adjusted according to the position of the clamping part in the clamping assembly.

[0013] Specifically, the second mounting base is provided with a second waist-shaped mounting hole, which is set along the width direction of the base; the lower end of the limiting rod is set in the second waist-shaped mounting hole and fixed by fasteners.

[0014] Preferably, the cutting blade has a toothed edge. Using a toothed blade prevents conductor slippage and facilitates cutting.
