Abstract:To reduce the rebar straightening power on conventional straightening machine, a new mould straightening principle with rotatinghub is proposed. According to this principle, three steel balls which rotate in any direction are mounted in a mould to transform sliding friction between rebar and balls into rolling friction. In this way, the force pushing rolls and straightening power are decreased greatly, and quality of straightened rebar can be obviously improved. The tolerance in straightness can be less than 1 mm per meter. The force and performance of this straightening machine are analyzed and calculated for designing.
