Abstract

The invention provides a pipe bending machine. A vertically arranged down-pressing oil cylinder is arranged on one side of the bed, an upper die is arranged at the lower end of the down-pressing oil cylinder, and a lower die is arranged directly below the upper die. The upper die and the lower die Model grooves are respectively arranged on the mating surfaces of the molds, and a push cylinder is horizontally arranged on the other side of the bed, and a push head is arranged at the front end of the push rod of the push cylinder, and a mold core is arranged inside the lower mold, and a mold core is arranged inside the mold. The tail end of the core is connected to the base, and the base is connected to the rotating shaft of the turning motor. A discharge device is arranged beside the base at the tail end of the mold core. The discharge device includes a fixed plate, a rotating plate and a telescopic oil cylinder. The two ends of the plate are respectively connected with the fixed plate and the piston rod of the telescopic oil cylinder, and a material shifting block is installed on the side of the mold core of the rotating plate. The pipe bending machine can improve production efficiency and reduce labor intensity of workers.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a pipe bending machine. Background technique [0002] In petrochemical, electric power, metallurgy, boiler and other industrial production equipment, pipelines are widely used for conveying gas, liquid or fluid with solid particles. [0003] The pipeline is composed of pipes, pipe fittings and pump valves. The pipe fittings generally have 6 varieties: elbows, tees, reducers, crosses, pipe caps and loose flange joints, among which elbows are the most important pipe fittings. Its consumption accounts for about 84% of the pipe fittings. [0004] At present, the manufacturing methods of elbows are extremely rich, including diameter expansion push bending method, tunnel extrusion method, mold pressing bending method, pressing sheet tailor welding method, shrimp waist bending method and so on. Among them, the tunnel extrusion method is always supported inside the billet during the w...
