Mechanical arm automatic loading type dual-head pipe bending machine

The invention discloses a mechanical arm automatic loading type dual-head pipe bending machine. The machine is mainly composed of arranging mechanisms, mechanical arms and pipe bending devices. Each arranging mechanism conveys one welding pipe upwards each time through cooperation of a conveying step plate and a fixed step plate, through a welding line detection unit, the circumferential positionof each welding pipe is located, through the mechanical arms, the circumferentially-positioned welding pipes are fed into the pipe bending devices, a welding line horizontal face is perpendicular to abending motion plane, and welding pipe breaking in the bending process can be prevented. 本发明公开了一种机械手自动上料式双头弯管机，主要由排料机构、机械手、弯管装置这三个部分组成，排料机构通过输送台阶板和固定台阶板进行配合每次将一根焊管往上输送，并通过焊缝检测单元来定位焊管周向位置，并通过机械手将周向定位好焊管送入弯管装置中，使焊缝水平面与折弯运动平面垂直，防止折弯过程中使焊管破裂。
