Title The blanking and punching composite die design of low carbon steel gasket
Abstract
The topic as 08 steel billet to the material, designs blanking and punching
composite die. First, I determine the technology programs and composite
die type used in the topic through the process analysis of the work piece.
Secondly, consulting the empirical formula in literature and calculating
the stamped and formed force of the work piece, as a basis for checking
mold strength, stiffness, and selecting the press. Then, based on the above
analysis and calculation, designing the working parts, fixed parts,
positioning parts, fastening parts, oriented parts of the die in order and
selecting the spring and the standard die base. Finally, according to the
structure parts and the installation location, drawing a die general
assembly drawing, and a brief description of the structural
characteristics and working processes of the composite die.
Keywords The technology Analysis The stamped and formed force
The die parts The general assembly drawing
