Abstract

The invention discloses a centering core shaft and an unrolling device. The centering core shaft comprises a core rod, a loop bar and a pressing piece. The loop bar sleeves the exterior of the core rod and is used for bearing a material roll. The pressing piece sleeves the exterior of the loop bar and is used for pressing and fixing the material roll. The loop bar and the pressing piece are additionally arranged on the centering core shaft, the material roll can be stably fixed to the core shaft in a centralized manner, axial playing is not likely to happen, centering of the material roll andthe centering core shaft is achieved, deformation or tensile failures are not likely to happen in the unrolling process, and the centering core shaft is compact in structure and convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of material coil uncoiling, in particular to a centering mandrel and an uncoiling device. Background technique [0002] In the industrial fields such as machinery, vehicles, metal products, household appliances, steel structures, decoration, etc., uncoiling operations of rolled materials are required to facilitate subsequent leveling and shearing processes. [0003] In the long-term research and development, the inventor of the present application has discovered that the material roll is usually lifted by a rigid rod, and the material roll is pulled by the material itself to realize the passive rotation and unwinding of the material roll. The material roll is prone to move along the rod axis and the material inlet position The problem of instability; at the same time, because the material roll and the rod are not concentric, the pulling of the non-steel material during the rotation will cause the material roll to d...
