Full Analysis Of The Operation Skills Of The Steel Bar Bending Machine

The steel bar bending machine is a key equipment used in construction to bend steel bars into the required shape. Mastering its operation skills can not only improve work efficiency, but also ensure the quality of bending and ensure the stability of the building structure. The following is a detailed introduction to the operation skills of the steel bar bending machine.

Preparation before operation

Equipment inspection: Before starting the steel bar bending machine, carefully check whether all parts of the equipment are intact. Check whether the working table of the bending machine is flat and whether there are any debris; check whether the bending center axis, forming axis, iron stop axis and other parts are worn or deformed. If there are any problems, they should be repaired or replaced in time. At the same time, ensure that the electrical system is normal, all buttons and switches are sensitive and reliable, and the grounding protection is good.

Rebar preparation: According to the construction requirements, select steel bars of appropriate specifications and materials. Clean the rust, oil and other impurities on the surface of the steel bar to avoid affecting the bending effect and the service life of the equipment. For longer steel bars, plan the placement in advance to ensure that the steel bars can move freely during the bending process and do not collide with surrounding objects.

Mold selection: According to the diameter and bending shape of the steel bar, select a matching bending mold. Different specifications of steel bars require different sizes of bending center axis and forming axis. For example, steel bars with smaller bending diameter can use smaller diameter center axis to ensure the accuracy of bending radius. When installing the mold, make sure it is firmly installed and correctly positioned to avoid loosening, displacement, etc. during the bending process.

Key skills in operation

Rebar placement and positioning: Place the steel bar steadily on the workbench of the bending machine so that one end is aligned with the bending center axis. According to the required bending angle and shape, use the positioning ruler or positioning device on the bending machine to accurately determine the bending position of the steel bar. When placing the steel bar, pay attention to the length direction of the steel bar being perpendicular to the bending direction to avoid bending deviation.

Bending speed control: After starting the bending machine, the bending speed should be reasonably controlled according to the material and diameter of the steel bar. For thinner or softer steel bars, the bending speed can be appropriately accelerated; for thicker or harder steel bars, the bending speed should be slowed down to avoid steel bar breakage or inaccurate bending shape due to excessive bending speed. During the bending process, closely observe the bending of the steel bar and adjust the bending speed at any time.

Bending angle control: During the steel bar bending process, the bending angle should be accurately controlled. The bending angle can be monitored in real time by observing the angle indicator on the bending machine or using an angle measuring tool (such as a protractor). When the required bending angle is reached, the bending machine should be stopped in time to avoid excessive bending. For some special shapes of bending (such as the 135° hook of stirrups), the operation should be strictly carried out in accordance with the design requirements to ensure the accuracy of the bending angle.

Multi-person collaboration: When bending longer or heavier steel bars, it is often necessary to collaborate with multiple people. The operators should have a clear division of labor and close cooperation. For example, one person is responsible for operating the bending machine to control the bending speed and angle; the other is responsible for supporting the steel bar to ensure that the position of the steel bar is stable during the bending process without shaking or displacement. At the same time, the operators should maintain good communication and timely transmit information to avoid operational errors.

Maintenance and maintenance after operation

Equipment cleaning: After the operation is completed, turn off the power of the steel bar bending machine in time, and clean up the debris, iron filings, etc. on the surface of the equipment and the workbench. Use a clean rag or brush to wipe the various parts of the bending machine clean to keep the equipment tidy. For some oil stains and rust that are difficult to clean, special cleaning agents can be used to clean them.

Component inspection and lubrication: Regularly check the various components of the bending machine, such as the center shaft, forming shaft, iron stop shaft, gears, chains, etc., to check whether there is wear, looseness or damage. For severely worn parts, they should be replaced in time; for loose parts, they should be tightened. At the same time, according to the instruction manual of the equipment, lubricate each lubrication point regularly, add an appropriate amount of lubricating oil or grease to reduce friction between parts and extend the service life of the equipment.

Safety protection device inspection: Check the safety protection devices of the steel bar bending machine, such as protective covers, emergency brake buttons, etc., to ensure that they are intact and function normally. Safety protection devices are important facilities to ensure the personal safety of operators. They must be carefully inspected before and after each use. If there are any problems, they should be repaired or replaced in time.
