Design of compound die for support foot of high speed steel barrel welding machine
Aiming at the requirement of using 2 mm thicknes SECC sheet material for small and me-dium batch stamping forming of electric machine support foot of high speed steel barrel welding machine,three dies were designed for the forming of four processes of the parts.Punching and blanking die and trimming and coining die were reversed compound die structure,cutting die and bending die were integrated in a die,with normal structure.The bending die was designed to be driven by a punch and a double slider adductive bending forming mechanism.The mechanism used sliders to clamp and drive bending on both sides of the bending wall of the parts,which could ef-fectively prevent the bending springback and ensure the bending forming size of the parts.The die structure was simple and practical,the forming process design was reasonable,and the automatic production of the parts was realized.
