The basic working principle of the bending upper mold

As an indispensable tool in the field of metalworking, the basic working principle involves bending the metal sheet at a specific angle and curvature. This process not only requires the upper mold to have sufficient strength and hardness to withstand the pressure in the processing process, but also requires the surface to have good wear resistance and fatigue resistance. For example, when manufacturing automobile body parts, the bent upper mold must be able to accurately bend the steel plate into the shape needed for the design to ensure the structural strength and appearance quality of the parts. According to the principle of material mechanics, the geometric design of the upper mode must consider the yield strength and elastic modulus of the material to avoid causing cracks or permanent deformation during bending. In practice, by using finite element analysis (FEA) models, engineers can predict and optimize the stress distribution of the modules under different loads to design economical and efficient bending modes.https://www.mhtcnc.com/product/bending-mold/
