Problems solved by technology
[0004] (1) Existing arch bending machines are still inconvenient for loading and unloading materials. Generally, cranes are used for hoisting, which is cumbersome to operate and has a high risk factor
[0005] (2) Existing arch bending machines are generally designed for section steel and cannot bend steel pipes; although some arch bending machines can be equipped with round or square tube rollers and bend steel pipes, they can only bend small-diameter steel pipes (outer diameter of steel pipes) or less than 150mm in side length), a small pipe diameter will easily lead to corrugation or pits on the inner arc side of the bent steel pipe, or the ellipticity of the steel pipe section, resulting in a decline in the later bearing capacity of the steel pipe
[0006] (3) It is impossible to realize continuous forming of arc arches with multiple curvature radii on the same section of steel pipe at one time

The invention relates to a numerically controlled one-step forming arch system and a working method, comprising a bending arch mechanism. The bending arch mechanism has a first roller, a second roller and a Three rollers, the first roller can move in the direction of the axis line connecting the second roller and the third roller. The two sides of the arch mechanism are respectively provided with a feeding support mechanism and a discharging support mechanism. The feeding support mechanism includes multiple A sliding rail is slidably connected with a bearing bracket, the bearing bracket is rotatably connected with a steering table, and the discharging support mechanism is used to support the bent profile.
Description
technical field [0001] The invention relates to the technical field of pipe forming equipment, in particular to a numerically controlled one-time rapid prototyping arch system. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] Steel pipe or profiled steel arches are widely used in the support of underground engineering. Currently, the commonly used arch bending techniques are divided into hot simmer bends and cold bends. Compared with cold bending, hot bending has high cost and low work efficiency. question. The cold-shaped pipe bending is low in cost and has a fast bending speed, which is carried out by an arch bending machine. However, the inventor found that the existing arch bending machine has many problems: [0004] (1) The existing arch bending machine still has the inconvenience of feeding and discharging materials. Generally, it is hoisted by crane, w...
