The data wire shell parts made of aluminum alloy were produced in a multi-position progressive die with 15 processes including multi-time trimming, four-time drawing, upsetting R angle, three-time thinning drawing, piercing and rotary cutting. The size of blank was obtained based on the experience value and the results of software simulation, and a strip with 42 mm wide was fed automatically by the automatic feeding machine. Then, forty-two guide pins with diameter of Φ2.5 mm were used to position precisely, and the feeding step was 32 mm. Furthermore, the structural design of thinning drawing station and rotary cutting station were introduced with the thinning thicknesses of 0.05, 0.03, 0.02 mm and the thinning coefficients of 0.88, 0.91, 0.94 respectively for three-time thinning drawing. However, twenty pairs of inner guide pins and inner guide bushings were set in the multi-position progressive die to reach high movement precision, and all of the key parts were designed as insert structure. Thus, the practical production shows that the quality of product is stable, and the production efficiency is high.
