Description

Three bundles of parallel core wire integrated stripping tool

technical field

The utility model relates to an electric wire peeling cutter, in particular to an integrated peeling cutter with three bundles of parallel core wires, which is suitable for automatic peeling machines.

Background technique

Wires are widely used in daily life. In general, 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 to use it. The conductive core is exposed 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 when it is not cooling. 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, there were also people who used tools such as wire strippers of various styles, but using wire strippers often caused adverse consequences such as cutting the conductive core. However, when peeling multiple bundles of parallel core wires 5, as shown in Figures 1 and 2, they are respectively three bundles of parallel core wire structures 5 and their bifurcations and schematic diagrams after peeling. 53 apart, and also must the sheath of both sides core wire end 51,52 be stripped than the sheath of middle core wire 53 end when the length is inconsistent, utilize above-mentioned several ways to be unable to carry out smoothly, moreover above-mentioned way also can only It is a manual operation method, which cannot form a large-scale peeling effect. For wire production enterprises, the production efficiency is obviously low and cannot meet the needs of current production.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figures 1 to 4, an integrated stripping tool for three bundles of parallel core wires, including a bifurcation knife mold 1, a first cutting knife mold 2, a second cutting knife mold 3 and a spacer plate 4, wherein:

The bifurcated die 1 is used to divide the core wires 51, 52, 53 of the three bundles of parallel core wires 5; it includes a male die 11 and a female die 12. The mold surface is provided with two upper and lower parallel bifurcated cutters 13, which are beneficial to the bifurcated cutters to split the three bundles of parallel core wires in advance.
