Traditionally, straight reinforcement bars are bent using a hand-operated mechanism. The accuracy of the bend depends on the skill and experience of the worker.
As an alternative to pneumatic and hydraulic machines, some machines can be used to make stirrups, but those machines have the major drawback of requiring a large storage tank and compressor, making the machine heavy and steady.
A bending machine is operated by electrical means, where the worker is only required to supply the bars and activate the switches. The machine is portable, so it can be taken anywhere. Low power consumption makes this automatic bending machine a preferred machine.
In the automotive, aerospace, construction, and shipbuilding industries, electric bending machines are often used for their high accuracy and ease of use. Heavy workpieces must be bent in the aerospace industry because of their precise nature.
In addition to offering precision, these bending machines are also more energy-efficient than other bending machines.
In this article we will discuss how can you can make a spiral on a steel bending machine and how you can straighten the already bent bars.
