Description

Wire threading processingequipment Technical Field The invention relates to the field of wire processing, in particular to a wire threading processing device. Background Silica gel wire is a special wire using silicone rubber as an insulating material, and is known for its excellent high and low temperature resistance (generally ranging from-60 ℃ to 200 ℃), excellent flexibility, good insulation and chemical stability. The characteristics make the device particularly suitable for the field of new energy sources (such as high-voltage wire bundles and charging systems in battery packs of new energy automobiles), internal wiring of various electric appliances and motors, and circuit connection scenes in severe environments, heat sources or frequent winding requirements in industrial machine equipment, and are key components for guaranteeing stable and safe operation of the equipment under extreme conditions. In the wire harness processing process of the silica gel wires, in order to meet the requirements of the application scene on mechanical protection, insulation reinforcement and convenient installation of the wire harness, a plurality of silica gel wires are often required to be integrated into one silica gel sleeve or a high-temperature-resistant corrugated pipe, and the threading processing common equipment comprises a semiautomatic threading machine which specifically operates such that an operator fixes the sleeve at one end of the equipment, puts wire heads into a guide port or a clamping device, and then pushes the wires into the sleeve through a foot switch or a button through a friction wheel or a simple push rod. In use and observation, it is found that in the threading process, in order to prevent the wire from exceeding one end of the sleeve due to overlong transmission, namely, excessive threading, two limiting measures are generally adopted, one limiting measure is manual intervention, namely, an operator visually detects the threading progress of the wire, the starting and stopping of the machine are manually controlled through a foot switch and other devices, a physical limiting element (such as a wire nose or a buckle) is pre-installed at the end part of the wire, when the component moves to the inlet of the sleeve, the component is blocked mechanically due to the fact that the size is larger than a pipe orifice, so that the wire is prevented from going deeper, however, the manual intervention mode excessively depends on manual visual observation, and is difficult to synchronize with the stable and high-speed working rhythm of the machine, the pre-installation of the structural element needs to additionally execute the installation operation of the limiting element, the disassembly operation is also needed for the detachable limiting element, and the complexity of the operation during wire threading is increased.
