The hydraulic section steel cold bending machine is widely used in the bending of I-beam, channel steel and section steel in road tunnels, railway tunnels, subway tunnels, water conservancy and hydropower diversion culverts, natural gas pipelines, communication pipelines, underground passages, etc. .
Among them, the application of I-beam bending machine is equivalent to the application of CNC section steel arch bending machine: the structural composition and working principle of the bending machine. The hydraulic cold bending machine consists of two sets of main motors and reducer groups, and active rollers. Put the I-beam on the cold bending machine, and after contacting the roller driven by deceleration, feed and lock the pressing handle, start the motor oil pump unit, and the high-pressure relief valve (adjustable pressure) output by the electric oil pump enters the manifold To the cable valve, there are electro-hydraulic valves and dynamic point switches (point in, point back) to control the work of the oil cylinder and the working oil.
Put the steel on the I-beam cold bending machine, and after contacting the deceleration drive roller, feed and lock the pressing handle, start the motor pump unit, and the electric pump will send the high pressure relief valve (adjustable pressure) to the integrated block. The cable valve has an electro-hydraulic valve and a moving point switch (point in, point out) to control the work of the cylinder. The working cylinder is pushed forward, and the I-beam is pressed against the three supporting parts, and the calculation is started when bending deformation occurs. The length of the cylinder is pushed forward. The process is 10mm-15mm, the main motor is turned on to drive the I-beam to work, and the operation is repeated until it reaches the desired level.
