Shape steel bending machine to make 18 I-beam, how to calculate the radian?
Cold bending machine, also known as curved arch machine, is mainly used in tunnels, subways, hydropower stations, underground chambers, such as I-beam, channel steel, angle steel, U steel and other profiles bending. Bending machine is a new equipment for tunnel support steel arch manufacture. It consists of six parts, such as pedestal, mechanical transmission, cold bending system, hydraulic system, electric control system and auxiliary system.
There is a scale on the cold bending machine, which means the size of the cylinder to push (that is, the arch height), the roller spacing (Xian Chang) is generally fixed, but also adjustable. According to the requirements of the project, the arch chord radius, high speed, and the actual operation requires propulsion cylinder.
First, determine the construction drawings of arch arch, hole radius, know high body width, the radius can be determined.
