Automatic machining device for pipe bends

The invention relates to an automatic machining device for pipe bends. The automatic machining device for the pipe bends is characterized in that the automatic machining device comprises a feeding mechanism, a clamping and moving mechanism, a transferring mechanism and a turning mechanism. The feeding mechanism can automatically feed materials onto a storage tank from goods shelves, and then the pipe bends are conveyed to the transferring mechanism through manipulators; when the conveying mechanism are full of the pipe bends, hydraulic cylinders act to clamp the pipe bends; and finally, the pipe bends are machined through tool heads, and full-automatic machining from loading to feeding is achieved. The manipulators are ingeniously used for preventing the pipe bends from falling, and grooves are ingeniously formed in a transmission shaft, so that friction between positioning bolts and the transmission shaft in the operating process is prevented; and in addition, semicircular structures are arranged on a suppor
