Beam bending machine, also known as the names, H-beam bending machine, I-beam bending machine, I beam bender is a special equipment for processing tunnel steel arch support. The processed steel arch can be widely used in the construction of railways, highways and hydraulic tunnels, as well as bridges, some large factory buildings. The machine is suitable for the bend of C section steel, I beam steel bar, angle steel bar, channel steel, rail, square steel, steel pipe, etc… Using the digital encoder programming to make the hydraulic control system positioning accurate, the I beam bending machine for sale in Yugong Machinery can make the bent steel form automatically at one time with high efficiency and convenient operation.

The Structure of Beam Bending Machine
The I beam bender is composed of two sets of main motor, reducer group, active roller, passive roller, oil pump motor, gear pump, overflow valve, hydraulic steering station and working cylinder. The machine replaces the original blanking, butt joint, calibration, processing and other complex processes, and can save oxygen, acetylene, labor, raw materials at the same time, which is a kind of cold bending equipment with high quality and benefit.
How to Bend I Beam
First, the section steel required for cold bending should be pushed between two active rollers by a portal bracket of the auxiliary system. Then start the hydraulic system of nc cold bending machine to make the hydraulic cylinder push the dovetail groove and cold bending roller to cold press the shaped steel. Close the hydraulic system when the required radian of the design is reached and start the mechanical transmission system to make the active roller rotate and drive the section steel forward smoothly and slowly depending on the friction force, so as to realize continuous cold bending. After the cold bending operation, close the mechanical transmission system and start the hydraulic system at the same time to retract the hydraulic cylinder. Then place the cold bending section steel on the portal bracket of the beam bending machine auxiliary system.
Safe Operation of I Beam Bender
- Strictly abide by the safe operation rules of machine tools, and wear labor protection articles as required.
- Clean and wipe the upper and lower molds before starting the machine.
- Check whether there is any other things on the pallet rack, stop rack and slide block. If there is any sundries, clean them up first.
- Select the appropriate die and the die size is generally equal to or greater than 8 times thickness of the sheet according to the thickness of the folded sheet.
- The bending force of the workpiece can be obtained by the bending force number of the sheet metal or the calculation formula of the bending force. The bending force of the workpiece shall not be greater than 1000KN.
- Please reduce the working pressure of the system appropriately to avoid damage to the mold when bending narrow plate.
- When adjusting the stroke of the slide block, the adjustment should be less than 100 to avoid damage to the machine.
- Before bending, the clearance between the upper and lower molds should be adjusted uniformly.
- When bending I beam steel, don’t put your hand between the molds. Only one piece of material may be bent at a time. Also check the oil level of the oil tank and start the oil pump to check whether there is any abnormality in the hydraulic pipeline and oil pump.
- Bending plate should be placed in the middle of the mold, the machine should not be unilateral load, so as not to affect the workpiece and machine precision. If some workpieces are required to work on one side, the load must not be more than 250KN, and must be bent on both sides at the same time.
- Stop the machine immediately if there is any abnormality, check the reason and handle the trouble in time.
- When the operation is completed, the oil pump should be closed, then exit the control system program and cut off the power.
