To improve threading processing efficiency and meet production requirement,by step-by-step research and integration of processes such as threading flattening and positioning,cold bending forming,thread forming on a rotary worktable,a reinforcement bar (short rebar) conveying and feeding device,setting a detection and adjustment function,a dual-gun 3D linkage automatic welding device,and a PLC integrated control system,the standardized,mass-producing and automated assembly line production of threading from raw materials to finished products was achieved.This allows for the production of various specifications of threading based on underground support needs,providing immediate supply,ready-to-use products,and seamless integration with underground frontline support requirements.This ensures strong support for underground support in the mining department,fully achieving self-sufficiency in thread-ing production.
