经过多次切边、4次普通拉深、镦R角、3次变薄拉深、冲孔和旋切落料等15个工序,在一套多工位级进模中实现了铝合金数据线壳零件的生产。采用经验值加软件仿真的方式获得拉深下料的外形尺寸。排样方案采用42 mm宽的条料,由自动送料机自动送料,42个Ф2.5 mm的导正销精定位,送料步距为32 mm。详细介绍了变薄拉深工位和旋切落料工位的结构设计,3次变薄拉深的变薄量分别为0.05,0.03和0.02 mm,变薄系数分别为0.88,0.91和0.94。为确保运动精度,模具设置了20对内导柱和内导套,且关键零件均设计成镶拼结构。通过实际生产验证,该模具生产的产品质量稳定,生产效率高。
After several trimming, 4 times normal drawing, upsetting R angle, 3 times thinning and drawing, punching and rotary blanking 15 processes, in a multi-station progressive die to achieve the aluminum alloy data Wire shell parts production. Empirical value plus software simulation method to obtain the drawing under the material dimensions. The layout program uses 42 mm wide strips, which are automatically fed by the automatic feeder, with 42 Ф2.5 mm guide pins for precise positioning, with a feeding step of 32 mm. The structure design of thinning and deep drawing station and rotary blanking station is introduced in detail. The thinning amount of three times of thinning and drawing are respectively 0.05, 0.03 and 0.02 mm, and the thinning coefficients are 0.88, 0.91 and 0.94 respectively. In order to ensure the accuracy of movement, the mold is equipped with 20 pairs of inner guide posts and inner guide sleeves, and the key parts are designed into a mosaic structure. Through the actual production verification, the mold product quality and stability, high production efficiency.
