Description
Technical Field
[0001] The invention relates to the technical field of copper wire cutting, and in particular to a copper wire production and cutting device. Background Art
[0002] Twisted copper wire refers to a conductive material formed by twisting multiple copper wires together in a certain structure and order. It is widely used in the field of electrical engineering, such as wires and cables, communication cables, etc. Twisted copper wire has excellent flexibility and anti-breaking performance, can adapt to frequent bending and movement, and can also reduce electromagnetic interference. When producing twisted copper wire, several strands of copper wire are generally twisted around a copper wire through a twisting machine. In order to improve the oxidation resistance of the copper wire and prevent the twisted copper wire from spreading, adhesive needs to be added to the surface of the copper wire.
[0003] After the production of the twisted copper wire is completed, in order to facilitate transportation and subsequent welding of the copper wire, the twisted copper wire needs to be straightened and then the ends of the twisted copper wire need to be cut. When the existing device cuts the twisted copper wire, the two ends of the copper wire are generally driven by a clamping mechanism, and the twisted copper wire is straightened by a moving mechanism, and then the copper wire is cut by a cutting machine. When this method is used to cut the twisted copper wire, the cutting knife cuts from one side of the twisted copper wire to the other side. At the same time, in order to ensure the straightness of the twisted copper wire, the twisted copper wire needs to be straightened. Tension is applied to both ends of the copper wire. When the cutting knife cuts the twisted copper wire, the number of copper wire strands subjected to the tension gradually decreases, which can easily cause the copper wire cut later to break or be over-stretched, thereby reducing the quality of the twisted copper wire. When the existing device clamps the twisted copper wire during cutting, it generally squeezes the side of the twisted copper wire through the anti-slip plate and clamps it through friction. During cutting, after one side of the copper wire is cut, the cut part of the copper wire moves downward under the action of gravity, causing the cut copper wire to easily loosen.
