Cutting tool assembly for peeling three bundle of parallel core wires and peeling machine using the same

Abstract

The invention relates to a three-bundle parallel core wire stripping toolbox and a stripping machine using the toolbox. The toolbox first branches off three bundles of parallel core wires by a branch cutting die, then precutting process is carried out on skins of the core wires at two sides and in the middle by a first cutting die and a second cutting die respectively, and a partition board arranged between the first cutting die and the second cutting die can ensured that a certain distance exists between the cutting positions of the core wires at two side parts and the core wire in the middle, so as to meet market requirements. The stripping machine precuts the skin at the end parts of the core wires by the toolbox driven by a first cylinder, and then drives the toolbox and the first cylinder to move along the core wire extending direction by a second cylinder, so that the toolbox can move to strip the precut skins under the condition that the core wires keep motionless, therefore, the manual work manner in the prior art can be replaced, the skins at the end parts of the core wires can be stripped off rapidly and conveniently, and the invention is suitable for mass production is high, thus improving the stripping efficiency.

Description

technical field [0001] The invention relates to wire and cable stripping technology, in particular to a cutter assembly for peeling three bundles of parallel core wires and a peeling machine using the cutter assembly. Background technique [0002] Wires and cables are widely used in daily life. Generally, the conductive core of the wire is wrapped by an insulating sheath. The insulating sheath is usually made of polyvinyl chloride. When wiring, it is usually necessary to peel off the sheath at the end of the wire and remove it. Expose the conductive core to connect the conductive core to other conductors; in order to peel off the sheath at the end of the wire smoothly, the most traditional method is to burn the sheath at the end of the wire with fire to soften the sheath, and quickly use your hands or Other tools tear it off, but the peeled skin is easy to stick to hands or tools, and because the fire temperature is difficult to control, there is also the possibility that th...

[0002] Wires and cables are widely used in daily life. Generally, the conductive core of the wire is wrapped by an insulating sheath. The insulating sheath is usually made of polyvinyl chloride. When wiring, it is usually necessary to peel off the sheath at the end of the wire and remove it. Expose the conductive core to connect the conductive core to other conductors; in order to peel off the sheath at the end of the wire smoothly, the most traditional method is to burn the sheath at the end of the wire with fire to soften the sheath, and quickly use your hands or Other tools tear it off, but the peeled skin is easy to stick to hands or tools, and because the fire temperature is difficult to control, there is also the possibility that the conductive core is oxidized

Later, some people used tools such as wire strippers of various styles, but the use of wire strippers often caused adverse consequences such as cutting the conductive core.

However, when stripping the three bundles of parallel core wires 5, as figure 1 , showing the unstripped state of the wire; figure 2 , the wire terminals are stripped; currently, for the three bundles of core wires 5, the industry needs to separate the core wires 51, 52, 53, and the sheaths of the core wire ends 51, 52 on both sides should be compared with the middle core. When the stripping length of the wire 53 end is inconsistent, so the above-mentioned methods cannot be carried out smoothly, moreover, the above-mentioned methods can only be performed manually, and cannot form a scale peeling effect. For electric wire production enterprises, Obviously, the production efficiency is low and cannot meet the needs of current production
