Any equipment has its purpose in the existence of the long process of development, the role of mechanical equipment is increasingly rich, and even can be said to be indispensable. So in the initial manual age, these devices are how to be developed out of it? But also in what kind of background application?
     For steel straightening machine, it is the construction of steel pipe scaffolding maintenance machinery. At the beginning of the time there is no such machinery and equipment, and later the scale of domestic construction has grown year by year, bamboo scaffolding was quickly replaced by construction steel pipe. However, the steel pipe after a long period of sun and rain, prone to rust corrosion, wall thinning in the construction demolition and handling of the process prone to bending the situation, shortening the service life, resulting in a series of security risks. In this background conditions, the steel straightening machine began to slowly appear embryonic form.
