the method comprises the following steps: the reinforcing steel bars which are moved in the horizontal direction are placed on the asymmetric supporting and guiding transmission devices (2), a plurality of groups of asymmetric supporting devices (30) on the same group of horizontal transmission chains (47) in the horizontal guiding devices (29) support the reinforcing steel bars, the horizontal power motor (43) works to drive the horizontal rotating bracket (45) to rotate, so that the horizontal transmission gear (46) drives the horizontal transmission chains (47) to move, and the asymmetric supporting devices (30) drive the reinforcing steel bars to move;

step two: then, a user places reinforcing steel bars needing to move in the vertical direction on a reinforcing steel bar vertical direction conveying platform (59) at the upper end, the inclined surfaces of the multiple groups of reinforcing steel bar guiding and conveying chutes (60) convey the reinforcing steel bars into the single group of reinforcing steel bar guiding and conveying vertical grooves (61), in order to avoid the reinforcing steel bars from accumulating at the connecting part of the multiple groups of reinforcing steel bar guiding and conveying chutes (60) and the single group of reinforcing steel bar guiding and conveying vertical grooves (61), the user controls a position-clamping-prevention power motor (64) to work, and the position-clamping-prevention rotating rollers (63) rotate and apply upward acting force to the reinforcing steel bars moving in the vertical direction, so that the reinforcing steel bars can smoothly move into the single group of reinforcing steel bar guiding and conveying vertical grooves (61);

step three: a user pulls an external force action pull rod (20) to provide an initial external force for a lever turnover reinforcing steel bar quantity limiting device (6), a lever adjusting rotating support (24) rotates by taking an adjusting support rotating limiting block (25) as a center, a reinforcing steel bar quantity limiting baffle plate (26) slides along a reinforcing steel bar quantity limiting plate sliding groove (27), a driving force adjusting lever (22) slides along a driving force lever sliding groove (21) to drive a potential energy action reinforcing steel bar guide groove baffle plate (12), a rotating limiting spring (14) connected between an upper end buffer type reinforcing steel bar guide tube plate (15) and a potential energy action rotating arc reinforcing steel bar limiting groove (11) deforms, the potential energy action rotating arc reinforcing steel bar limiting groove (11) is separated from a single-group reinforcing steel bar guiding and transporting vertical groove (61) through the potential energy action reinforcing steel bar guide groove baffle plate (12), and when a reinforcing steel bar dislocation quantity guide opening (28) and the single-group reinforcing steel bar guiding and transporting vertical groove (61) are overlapped, the reinforcing steel bars in the vertical direction pass through the reinforcing steel bar dislocation quantity flow guide ports (28) and fall to the position above the potential energy acting reinforcing steel bar guide groove baffle plate (12), only one group of reinforcing steel bars can be placed at the height between the reinforcing steel bar quantity limiting baffle plate (26) and the potential energy acting reinforcing steel bar guide groove baffle plate (12), when a user restores an external force acting pull rod (20) to an initial state, the reinforcing steel bar dislocation quantity flow guide ports (28) are disconnected with a single group of reinforcing steel bar guiding and transporting vertical grooves (61), the potential energy acting rotary arc reinforcing steel bar limiting grooves (11) are connected with the single group of reinforcing steel bar guiding and transporting vertical grooves (61), one group of reinforcing steel bars moving in the vertical direction roll along through holes in the upper end buffer type reinforcing steel bar guide tube plate (15), sequentially pass through the potential energy rotary energy guide inclined tube plate (16) and the bottom end reinforcing steel bar discharging limiting and bending tube plate (17), and fall on the asymmetric supporting device (30), the falling reinforcing steel bars are limited by a first side upper reinforcing steel bar guiding and transporting chute (36) and a second side upper reinforcing steel bar guiding and transporting chute (40) and roll towards the direction of a bottom plate (32) of the horizontal conveying device, then the falling reinforcing steel bars are limited by a first side reinforcing steel bar fixing arc groove (37) and a second side reinforcing steel bar fixing arc groove (41) and fixed in the horizontal direction, so that two groups of reinforcing steel bars which are mutually vertical are in contact connection on an asymmetric supporting device (30), because a bottom reinforcing steel bar discharging limiting bending tube plate (17) is subjected to the action of kinetic energy and pressure of the falling reinforcing steel bars, when the reinforcing steel bars in the vertical direction are separated from the bottom reinforcing steel bar discharging limiting bending tube plate (17), a rotation limiting spring (14) connected between an upper buffer type reinforcing steel bar guiding tube plate (15) and a potential energy action rotating arc reinforcing steel bar limiting groove (11) is restored to an initial state, a potential energy acting reinforcing steel bar guiding groove shielding plate (12) rotates the arc reinforcing steel bar limiting groove (11) to slide along the potential energy action, the main power transfer lever (22) pushes the lever to adjust the rotating bracket (24) to rotate, the reinforcing steel bar dislocation quantity diversion port (28) on the reinforcing steel bar quantity limiting baffle plate (26) is overlapped with the single-group reinforcing steel bar guiding and transporting vertical groove (61) again, the reinforcing steel bar with the upper end dropping is transported downwards, the reinforcing steel bar quantity limiting baffle plate (26) continuously slides to continuously transport the vertically dropping reinforcing steel bar to the asymmetric supporting and guiding transmission device (2) through the continuous rotation of the reinforcing steel bar transmission limiting device (9), and two groups of mutually staggered reinforcing steel bar materials are constructed;

step four: when the reinforcing steel bars falling from the upper end of the reinforcing steel bars and the horizontally moving reinforcing steel bars are in staggered contact, the horizontal power motor (43) drives the reinforcing steel bars on the asymmetric supporting device (30) to further move forwards, when the staggered contact points of the two groups of reinforcing steel bars reach the upper part of the welding working device (4), the horizontal power motor (43) stops working, the welding rotating main power motor (51) works, the welding main power gear (52) drives the welding synchronous gear (53) to rotate, the welding main bending bracket (54) rotates along the main welding bracket rotating groove (49), the welding synchronous bending bracket (55) rotates along the synchronous welding bracket rotating groove (50), the main welding gun head (56) moves along the first side welding head telescopic opening (38), the synchronous welding gun head (57) moves along the second side welding head telescopic opening (42), the two groups of welding guns work, and the connecting parts of the two groups of reinforcing steel bars which are in staggered arrangement are connected in a hot melting way, after spot welding is finished, the main welding gun head (56) and the synchronous welding gun head (57) return to the initial positions respectively, the horizontal power motor (43) works to enable the asymmetric supporting device (30) to continue to move, and the welding work of the reinforcing steel bar supporting net is gradually realized by matching with reinforcing steel bars with upper ends which drop discontinuously.
