定义
A mandrel shaft is a critical cylindrical tooling component in industrial press systems, specifically designed for stacking mandrel applications. It provides precise alignment, support, and forming surfaces during material processing operations such as coiling, winding, or pressing of sheet materials, tubes, or composite structures. The shaft maintains dimensional stability under high radial and axial loads while ensuring consistent product geometry.
工作原理
The mandrel shaft operates by providing a rigid cylindrical form around which materials are wound, stacked, or pressed. During operation, it maintains precise alignment through bearing surfaces while withstanding torsional and compressive forces from the press mechanism. The shaft's dimensional accuracy ensures uniform material distribution and prevents deformation during high-pressure forming processes.
材料
High-strength alloy steel (AISI 4140/4340)hardened to 45-50 HRC with surface treatments (chrome plating or nitriding) for wear resistance. Alternative materials include tool steel (D2H13) for high-temperature applications or carbide-tipped designs for abrasive materials.
