Abstract：

The layout and structure of multi-position progressive die were designed for the bidirectional isolated pad in consideration of the forming difficulty and technical requirement. The design of guiding devices, locations, strippers and working parts were described in detail. The sliding guide die for diagonal pillar sets with high guiding precision were selected, which operated smoothly without deflection. The spring guide plate guiding punch was designed to improve guiding precision and protect small punches. The nesting with scrap, bridge and center carrier was designed to enhance the rigidity of strip. Double-sided blades were symmetrically installed and the location was guided by bilateral stock guides. The fixed end dimension of small punch was enlarged to increase its strength and rigidity. The die with inserts was designed to reduce the manufacturing complexity and for the convenience of sharpening and maintenance. Spring strippers were operated reliably and safely to ensure feeding smoothly and improve productivity. The strip was pressed before stamping to ensure the flatness and straight of parts and strips, while prevent from deviation in the process of bending and reduce the springback. The production results show that quality and productivity can be achieved by the multi-position die with bidirectional isolated pad.
