This invention discloses a manufacturing and forming method for steel wire mesh reinforced tubes, relating to the technical field of steel wire mesh reinforced tubes. The method includes the following steps: S1, fixing the steel wire unwinding coil onto the cross-shaped positioning rod using a cross-shaped positioning rod, and using the magnetic force of a stopping electromagnetic ring to attract and fix the position of the metal limiting block and the cross-shaped positioning rod. The steel wire is then passed through the steel wire docking box, tensioning guide wheel, burr removal channel, and steel wire welding wheel located at the top of the welding support shaft seat. This invention has a scientifically sound and reasonable structure, and is safe and convenient to use. Through the cooperation of a detection camera, electrically controlled wire clamping pliers, a sleeve electric push rod, and hydraulic crimping pliers, the detection camera observes the steel wire passing through the steel wire docking box, thereby clamping and fixing the end of the old steel wire, limiting it below the hydraulic crimping pliers to prevent the steel wire from running out. Simultaneously, it facilitates moving the hydraulic crimping pliers and sleeve to the top of the end of the old steel wire.
