Through the design of the die parts, to further strengthen the basic knowledge of the designers of the progressive die design, which paves the way for a more profound experience and lessons for the design of more complex progressive die. The use of design drawing based blanking bending forming process and die design is, firstly analyzes the requirements of cost and performance parts, ready for the selection of process scheme for the types of mold; then analyzed the shape and size of parts, easy selection of die; finally analyses the parts feature selection, design and mold design parameter die of. This part is the design of progressive die for the backrest plate part level, the blanking and punching, bending and other design in a die, the die has the advantages of simple operation, high production efficiency, reliable performance. This design through process integrated parts of the economy, including the comprehensive analysis of parts, stamping process analysis, analysis and determine the stamping process scheme, compared schemes from scheme, scheme two, scheme three, scheme four, the fifth scheme, finally determined the scheme. Then the process calculation, including calculation of blank size, layout and the conference board, cutting method, steps to determine the distance accuracy, blanking force calculation, falling process, punching material process, bending process, and the mould structure form selection, determine and check discharge device, positioning device, die and punch and die cutting edge size. Finally, mold design, mold design of the working parts, and so on a series of design, the design of all one one are described. Only with such a complete set of design.
