Abstract
A study on the stam** process of a chair surface with complex profiles made from SS400 material sheets, this part is welded to the mounting bracket used for transporting mining workers in the mines. During the stam** process, the seat surface often appears tearing at the front position of the seat. This position has non-uniform deformation, a large degree of deformation is easy to tear, and the surface after deformation will be uneven, affecting the quality and aesthetics of the product. Defects occur when stam** the seat surface due to many reasons such as the calculation of the initial profile of the workpiece, selection of geometrical parameters, and inappropriate technology. Therefore, this study has conducted a simulation of the stam** process with different types of billet profiles, after being simulated stam**, the deformation and thickness will be determined at many locations. From there, select the appropriate billet profile so that the part after stam** does not appear to be torn, ensuring the size requirements and no need to add rim cutting operations. The suitable workpiece profile will be simulated and verified with the corresponding experiment.
