某型穿甲弹尾翼片是用LC4板材为坯料的锻件。由于坯料采用无精确定位的平刃剪单件下料,不仅浪费料,工效低,而且严重影响尾翼片质量。因此,设计和制造高质量高效率的下料模具,便成为急待解决的一个课题。为此,我们自行设计制造了双下料模具,在生产中发挥了较大作用,使这一课题得到了较好的解决。一、平刃剪单件下料和尾翼片质量尾翼片所用LC4板为2000×1500×8毫米。首先在平刃剪上按垂直纤维方向裁成170±1.0
A type of armor-piercing projectile flaps are made of LC4 sheet forgings. As the blanks with no precise positioning of the flat blade cut a single cutting, not only a waste of material, low efficiency, but also seriously affect the quality of tail pieces. Therefore, the design and manufacture of high quality and high efficiency of the die, it has become an urgent issue. To this end, we design and manufacture of double blanking die, played a greater role in the production, so that this issue has been better resolved. First, the flat blade cutting a single piece and tail fin quality tail piece LC4 board used for 2000 × 1500 × 8 mm. First of all, flat blade cut by vertical fiber direction cut 170 ± 1.0
