Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to a cycloidal stripping shears and braiding machine. Background Art

[0002] Cables are the wiring components that connect various electrical devices in the circuit. They are composed of core wires, braids, insulation skins, etc. The quality of cables is directly related to whether the entire electrical equipment can work normally and safely. During the cable processing, after the insulation skin is processed, the exposed braids must be cut off. Generally, manual operations are used in the process of cutting the braids. This working method is slow and inefficient, and a large amount of manpower and material resources are wasted. The degree of automation is low, and the processing accuracy is low, which affects the quality of the product. If shearing is performed mechanically, it is easy to cause the incision to be not neat, affecting the connection of the cable. The braid is formed by winding multiple strands of wire. If the incision is not neat, there will be uneven thread ends, which will have an adverse effect on the connection of the cable, and even cause the electrical equipment to have poor contact and cannot be used normally. However, in the prior art, the braid outside the core is often peeled off from both sides and the excess part is cut off, but a smooth and neat incision cannot be achieved. Summary of the invention
