Anti-scratch arc-shaped slide carriage device of coiling machine

Abstract

Strip steel passes through the space between an upper pinch roll and a lower pinch roll and is curled into a steel coil around a core rod through a wrapper roll, one end of a slide carriage is connected with the wrapper roll, the other end of the slide carriage is connected with the upper pinch roll, and the slide carriage is sunken towards the outer side of the steel coil. The recesses arranged on the slide carriage reserve enough space for the arch shape of the tail of the strip steel when the thickness of the strip steel is large, so that the slide carriage and the strip steel are not contacted any more when the wrapper roll presses the tail, and the problem that the strip steel is scratched due to tail pressing is avoided.
