Uncoiler Mandrel of Steel Strip Galvanized Line

The mandrel of steel strip galvanized wire mandrel is an important component of uncoiler and reoiler. The core shaft has high tension and high precision. Each part of this product has strict requirements from design to processing, and the workpiece verticality, parallelism, and coaxiality are strictly in accordance with the drawing requirements. In particular, the root is chamfered. Nitriding treatment is carried out on the external circular surface of the sector plate and the support sleeve to increase the wear resistance and fatigue resistance. After assembly and grinding, the contact rate of the work level reaches 70%-80%, the coaxiality of the spindle bearing position and gear position is within 0.02mm, and the consistency of the sector plate is 0.1mm-0.15mm. At the same time, the German SMS group Shougang project, which our company exported before, consistently meets their acceptance standards.
