How to debug the twist of the I-beam bent by the cold bending machine
The I-beam cold bending machine realizes continuous operation on the basis of ensuring the strength of the steel, the section is economical and reasonable, and the material is saved. The section shape of the cold bending machine can be designed according to the needs, the structure is reasonable, and the section coefficient per unit weight is higher than that of the hot-rolled section steel. Under the same load, the weight of components can be reduced and materials can be saved. It meets the various requirements of different design sizes, improves the quality of the cold bending machine, speeds up the processing speed, and greatly reduces the labor intensity, saves a lot of manpower and material resources, and achieves good economic and social benefits in practice. The following will share with you how to debug the twist of I-beam bent by the cold bending machine.
1. Before debugging, add lubricating oil, and check whether all parts are in good condition, whether the rotation direction of the oil pump is consistent with the specified direction, and check whether there are cracks in the processing parts, pressure pads, top pads, and support pads. After the test run is confirmed to be normal, the work can be started.
2. Then put the section steel on the bracket and wear it in the fixing frame of the bending machine. The section steel is stuck in the two rolling wheels, and pay attention to adjust it on the same level.
3. Start the oil pump button, operate the reversing rod to make the top of the oil cylinder roll on the section steel, observe the scale on the top of the oil cylinder after exerting force, and start to bend 3~4cm, start the forward (left) feeding button, and let the section steel move toward Move the front (left) evenly, stop when it is in place, measure the bending degree of the section steel, release the cylinder jack and remove the section steel after meeting the requirements, and then operate the reversing rod to make the cylinder top pressurize the bending section steel, bend 1~2cm, and start Press the feed button backward (right) to move the section steel evenly backward (right), stop when it is in place, measure the bending degree of the section steel, release the cylinder top and remove the section steel after meeting the requirements, and continue to bend until the requirements are met. It must be noted that the section steel is indeed stuck in the rolling wheel before the hydraulic cold bending machine can be started.
4. People are not allowed to stand within the rotation radius of the curved steel and on both sides of the fuselage feed. The bent semi-finished products should be stacked neatly.
5. When bending long section steel, a special bracket should be provided. The person who supports the steel should work according to the command of the operator, and should not push or pull arbitrarily.
6. It is strictly forbidden to bend the section steel that exceeds the type specified by the I-beam cold bending machine. Wear protective goggles when bending undrawn or rusted steel.
7. Arrange the processed section steel components neatly according to the fixed management requirements, and place the pads flat and firm.
8. After the work is completed, cut off the power supply, clean the workplace and the I-beam cold bending machine, and do a good job in the maintenance of the hydraulic I-beam cold bending machine. It is forbidden to use your fingers to dig rust in the pits.
