Title:
STEEL BAR BENDING MACHINE FOR CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2020/206574
Kind Code:
A1
Abstract:
A steel bar bending machine for construction, comprising: a base (1), wherein a front end surface of the base (1) is sequentially provided from left to right with a turntable (2), a fixed block (3) and a lower driven roller (4); the center of the turntable is connected to a rotating rod (5) by means of a bearing; the rear end of the rotating rod penetrates through the front end surface of the base to be provided with a rotating motor (6); a connecting block (7) is arranged on the left side of the front end surface of the turntable; a left-right run-through moving groove is arranged on the front end surface of the connecting block; a sleeve (8) is clamped in the moving groove; when a steel bar is bent, an upper fixed block (22) moves up and down to fix steel bars of different diameters; and then the rotating motor is turned on to drive the rotating rod and the turntable to rotate; a plunger is inserted into a corresponding limit hole (19) as needed; when the sleeve rotates to the position of the plunger, the plunger prevents the sleeve from continuing to rotate, and a steel bar with required bending angle is obtained; and elastic forces generated by the deformation of a spring telescopic rod (10) and a spring (26) compress the steel bar to prevent the steel bar from slipping and loosening during bending.
