Abstract

A steel pipe large-arc single-cylinder hydraulic forming device comprises a hydraulic machine, an upper machine table, a lower machine base, a male die template, a female die template and a driving module. The hydraulic machine pushes the die to bend and form a steel pipe; multi-roller forming is replaced with the single rotatable male die template; the size of a steel pipe can be well controlledduring large-arc forming through movable limiting of a driving motor and a limiting rack. The device has the advantages of being high in forming speed, easy to adjust, high in machining efficiency andcapable of rapidly machining large-arc bent pipe metal plate structural parts of different sizes.

Description

technical field [0001] The invention relates to a press-forming device, in particular to a single-cylinder hydraulic forming device, in particular to a large-arc single-cylinder hydraulic forming device for steel pipes. Background technique [0002] Among all kinds of sheet metal structural parts, the production of curved pipe sheet metal structural parts takes more manpower and material resources than rectangular, polygonal and other shaped structural parts. The main reason is that the curved pipe sheet metal structural parts are in the It is difficult to ensure the accuracy of cross-sectional dimensions during production. During the steel pipe bending process, ordinary steel pipe bending machines can only make steel pipes into steel pipes with various angles, but cannot bend steel pipes into larger arc shapes. If the steel pipe is to be bent into a larger arc shape, it is necessary to invest a large amount of money to purchase special equipment, which will inevitably incr...
