　　Tunnel CNC Cold Bending Machine Jingheng Culvert Arch Bending Machine Sales Base

　　CNC cold bending machines are now widely available in the market, and they can complete the bending and arching tasks of various types of steel, including channel steel, track steel, and round steel pipes. Different types of steel arches and arches with different angles require different grinding tools. The recognition of the bending machine in the market is very high now. Greatly improving the construction speed of profiles and saving labor for workers.

　　The I-beam cold bending machine is controlled through the operation screen during operation. Learning cold bending machine technology requires understanding the composition and control methods of the cold bending machine operation panel. One way is to turn on the power, turn on the key switch on the control panel, and then press the oil pump start button to hear the sound of the oil pump, and the machine will not run. Pay attention to adjusting the stroke of the cold bending machine during use. Test before cold bending. When the upper bending mold of the cold bending machine descends to the bottom, ensure a gap in plate thickness, otherwise it will cause damage to the mold and machine. The itinerary adjustment is also equipped with electric quick adjustment and manual fine adjustment. It should be noted that the operation of the cold bending machine should not exceed the small closing height, that is, the small distance from the bottom surface of the upper sliding box to the working surface is 290mm. The mold should be manufactured according to this requirement in order to avoid machine accidents. The sales base of the CNC cold bending machine for tunnels, precision culverts, and arch bending machines should be established.

　　Structure and working principle:

　　1. The I-beam cold bending machine consists of a main motor, reducer, roller, oil pump motor, gear oil pump, overflow valve, electromagnetic reversing valve, working oil cylinder, top wheel, and oil tank. Please refer to the electrical schematic and hydraulic schematic.

　　2. Working principle of I-beam cold bending machine: Place the I-beam on the cold bending machine, contact it with the roller driven by the reducer, feed the clamping handle to lock it, start the motor oil pump group, and the high-pressure oil output by the electric oil pump enters the aggregation block through the overflow valve (adjustable pressure) to the electro-hydraulic valve. There are electro-hydraulic valves and jog switches (jog in and jog out) to control the oil cylinder to work. The working oil cylinder pushes forward and presses the I-beam tightly with the three supporting rollers without bending deformation. The length of the oil cylinder's further pushing process is 10mm-15mm each time. Turn on the main motor to rotate forward or reverse, and the I-beam is driven by the main motor to work. Repeat the operation until it reaches the required precision of the tunnel CNC cold bending machine. Henghan Tunnel Bending Machine Sales Base.
