A recycling waste and old electric-wire automatic core pulling and disassembling method is disclosed. The method comprises the following steps of step1, charging; step2, carrying out wire trimming; step3, hooking a wire; step4, breaking the wire; step5, cutting a surface; step6, carrying out core pulling; and step7, discharging. In the technical scheme, an automation degree of equipment is increased, working procedures are simplified, wire feeding setting and sectioning setting in the previous technical scheme are especially omitted, an equipment structure is simplified and performance is stable. A disassembled electric wire surface and an electric wire metal core are high-efficiently and automatically separated and enter into corresponding containers so that a technical problem that separation of a final link in electric wire disassembling production needs manual assistance is completely solved; one-piece automation of all processes of electric wire disassembling production is realized, work efficiency is increased and labor cost is saved; a waste and old electric cable disassembling device is environmental-protection and energy-saving, the structure is simple, the device is easyto manufacture, performance is stable, and waste and old electric cables can be high-efficiently and rapidly arranged.
