Description

Technical Field

[0001] The invention relates to the field of stamping and forming equipment, in particular to special-shaped steel hot forging and stamping forming equipment and a process thereof. Background Art

[0002] Special-shaped steel refers to the abbreviation of complex and special-shaped cross-section steel. Special-shaped steel is processed by stamping due to its complex size. Stamping is a forming processing method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Hot forging and stamping can reduce the deformation resistance of the metal, thereby reducing the forging pressure required for the deformation of the blank and reducing the tonnage of the forging equipment. Hot forging and stamping are widely used in the processing of special-shaped steel. Due to its complex shape, special-shaped steel usually requires multiple stamping processes to complete the final forming. The flow between multiple stamping processes will cause continuous heat loss of the workpiece, which is easy to affect the stamping effect of the subsequent stamping process.
