What is Cold Bending Mould?
Cold bending moulds are precision tooling systems designed for shaping metal components through bending operations at room temperature. These moulds consist of carefully engineered punch and cavity components, along with specialized pressure pads and guide systems that ensure accurate material positioning and controlled deformation. The design must account for spring back characteristics and material properties to achieve precise final geometries.
The primary function of cold bending moulds is to produce bent components with high accuracy and consistency. They are widely used in manufacturing industries to create structural elements, brackets, automotive components, and various formed metal parts. This process offers advantages such as high production rates, minimal material waste, and the ability to maintain material properties since no heating is required. Cold bending moulds can handle various material thicknesses and profiles while ensuring consistent bend angles and dimensional accuracy.
The mould materials used in cold bending applications contain specific alloying elements to withstand repeated bending operations. High-grade tool steels are employed, incorporating combinations of chromium, tungsten, molybdenum, and vanadium to achieve optimal performance characteristics. These materials provide the necessary hardness and wear resistance while maintaining sufficient toughness to prevent cracking under bending loads. The microstructure features carefully controlled carbide distributions that ensure excellent wear resistance and dimensional stability. Surface treatments are often applied to enhance durability and reduce friction during the bending process, particularly important for preventing material galling and surface damage.
