Detailed Description
The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The vertical wire upper top bending mechanism 4 and the vertical wire lower top bending mechanism 5 are consistent in structure and are symmetrically arranged on the upper side and the lower side of the vertical wire 601;
Taking a longitudinal wire upper jackbending mechanism 4 as an example, the longitudinal wire upper jackbending mechanism 4 comprises a mounting seat 101, a lifting seat 103, a plurality of jackbending seats 105 and supporting rollers 108, wherein the mounting seat 101 is arranged on a feeding conveying frame 1 through a bracket 102, the lifting seat 103 is vertically and slidably arranged on the mounting seat 101, a limit slide rod 501 is fixedly connected to the mounting seat 101 for stable lifting of the lifting seat 103, a supporting plate 502 is connected to the lifting seat 103, the supporting plate 502 is slidably arranged on the limit slide rod 501, a lifting cylinder 104 is arranged on the mounting seat 101, the output end of the lifting cylinder 104 is connected with the lifting seat 103 and used for controlling the lifting cylinder 104 to perform lifting adjustment, the jackbending seats 105 are arranged into a plurality of jackbending seats 105, the output ends of the jackbending seats 107 are connected with a connecting plate 106 and the jackbending seats 105 to perform lifting adjustment, the supporting rollers 108 are arranged into two, the supporting rollers 108 are used for supporting longitudinal wires 601, in particular, the jackbending seats 105 are arranged between the two supporting rollers 108, the two supporting rollers 108 are used for supporting the longitudinal wires 5 and the longitudinal wires 5 are used for supporting the longitudinal wire upper and lower bending mechanism 5 when the two jackscrews are bent at the side of the jack 5, and the jack-bending mechanism is shown in the drawing 5;
When the jacking cylinder 107 is started, the connecting plate 106 is driven to lift, the connecting plate 106 simultaneously drives the plurality of jacking bending seats 105 to jack up the plurality of spaced longitudinal wires 601, as the two supporting rollers 108 of the longitudinal wire upper jacking bending mechanism 4 are supported on the lower side of the longitudinal wires 601 when the jacking bending seats 105 of the longitudinal wire upper jacking bending mechanism 4 are lifted, the two supporting rollers 108 of the longitudinal wire lower jacking bending mechanism 5 are supported on the upper side of the longitudinal wires 601 when the jacking bending seats 105 of the longitudinal wire upper jacking bending mechanism 4 are lifted, when the longitudinal wires 601 are jacked up, the two sides of the jacking position are supported by the two supporting rollers 108, so that the position cannot form a gentle slope shape, and a similar semi-ring shape is formed, and the contact area of the intersection of the longitudinal wires 601 and the transverse wires 602 is smaller due to the gentle slope-shaped protrusions, so that the connection strength is relatively reduced;
As shown in fig. 7 to 9, a space similar to a circle is formed at the upward bending position and the downward bending position of the plurality of longitudinal wires 601 at intervals, and the space can be used for inserting and placing the transverse wires 602, compared with the arrangement mode of the plurality of transverse wires 602 at one side of the plurality of longitudinal wires 601 in the prior art, the method can achieve the effects that the plurality of transverse wires 602 and the plurality of longitudinal wires 601 are combined together in a crisscross manner, so that a more integral composite structure is formed, the firmness of the reinforcing steel bar net sheet is enhanced, and the reinforcing steel bar net sheet is more difficult to separate, crack or fatigue fracture;
After the top bending is completed, an upward or downward bulge is formed on the longitudinal wire 601, and the vertical wire 601 cannot be conveyed to the direction of the welding mechanism 2 any more due to the blocking of the supporting roller 108, so that after the top bending is completed, the lifting seat 103, the top bending seat 105 and the supporting roller 108 need to be temporarily away from the longitudinal wire 601, a space for conveying the bulge to the direction of the welding mechanism 2 is reserved, specifically, when the top bending is completed, the lifting cylinder 104 is started to drive the lifting seat 103 to slide and lift in the direction away from the longitudinal wire 601, and after the bulge just formed is conveyed to the direction of the welding mechanism 2 one step, the lifting cylinder 104 is restored to drive the lifting seat 103 to slide and lift in the direction of the longitudinal wire 601, so that the next bulge top bending is convenient to continue;
