The invention provides a portable U-shaped pipe bending machine, and relates to the field of steel pipe forming machines, in particular to structures of pipe bending machines. The portable U-shaped pipe bending machine comprises a machine frame, an upper working plate and a lower working plate are arranged on the machine frame, two groups of roller frames are arranged between the upper working plate and the lower working plate, the two groups of roller frames are arranged at the left end of the upper working plate and the right end of the upper working plate respectively, the two groups of roller frames, the upper working plate and the lower working plate are connected through first pin rolls, and in each group of roller frames, rollers are connected through second pin rolls. The middle of the upper working plate is fixedly connected with an upper connecting frame, the middle of the lower working plate is fixedly connected with a lower connecting frame, the other end of the upper connecting frame and the other end of the lower connecting frame are connected with the same square block, and the square block is fixedly connected with the machine frame. An oil cylinder is connected onto the machine frame and comprises a cylinder barrel and a piston rod, the front end of the cylinder barrel is arranged in the square block in a penetrating mode, and the front end of the piston rod is fixedly connected with a semicircular mold. A pipe to be bent can be bent by 180 degrees through the portable U-shaped pipe bending machine, and the portable U-shaped pipe bending machine is simple in structure, convenient to operate and low in use cost.
Description
technical field [0001] The invention relates to the field of steel pipe shaping machinery, in particular to the structure of a pipe bending machine. Background technique [0002] Pipe bending machines are mainly used for bending pipes and sheets, and are generally used for auxiliary installation and repair of pipelines in power construction, road, railway construction, boilers, bridges, ships, furniture, decoration, etc. The traditional pipe bending machines include CNC pipe bending machine and hydraulic pipe bending machine. The numerical control pipe bending machine has high pipe bending efficiency and accurate pipe bending angle, but it is expensive and the cost of use is high. Although the hydraulic pipe bender is easy to operate, due to the unreasonable structure, it can only bend the bent pipe to 90°. Contents of the invention [0003] The object of the present invention is to provide a portable U-shaped pipe bender that can be bent to 180° in order to overcome the ...
