摘　　要：针对冲出装饰扣产品口部向内卷边的圆环状扣位的难点,设计了一套多工位级进模具。为了冲出产品口部约3/4圆周的扣位,分3个工位冲压产品上的扣位,每个工位冲出扣位的1/3,每个扣位工位上的工序模由斜顶块、T形导轨、凹模、橡胶块、顶杆和氮气弹簧组成,由氮气弹簧推动斜顶块脱模。为了提升级进模具的工作效率、节省原材料,采用一出二的多工位级进模具。为了顺利提起料带,采用抬料销、弹簧销钉和导正销相结合的抬料结构,克服了在料带上裁剪出落料件后,无法使用抬料销抬料的问题。在模具工序的结尾处,安装了检测装置,检测到产品离开模具后才开始下次冲压。经批量生产证明,此级进模具结构稳定、可靠,有一定参考价值。For the decorative buckle, it was pointed out that the circular buckle position rolled inward at mouth of product had the difficulty of stamping. A set of multi-station progressive die was designed. In order to punch out the buckle position about 3/4 circumference at the mouth of product, the buckle position of product was punched in three stations, and 1/3 buckle position was punched out in each station. Then, the working procedure die in each station of buckle position was composed of inclined top block, T-shaped guide rail, die, rubber block, ejector rod and nitrogen gas spring, and the nitrogen gas spring pushed the inclined top block out of the die. Furthermore, a multi-station progressive die that could produce two parts at a time was designed to improve the work efficiency of progressive die and save raw materials, and the material lifting structure combining material lifting pin, spring pin and guide pin was adopted so as to lift the material belt smoothly, which overcame the problem that the material could not be lifted by the material lifting pin after blanking the part on material belt. Finally, at the end of the die process, a detection device was installed to detect that the mext stamping was started after the product left the die. The batch production proves that the structure of progressive dis is stable and reliable which has certain reference value.
