红菱24型自行车和红菱50型两用车,需要生产各种不同直径的圆管形护套工件,直径分别为:φ14mm×2mm,φ18mm×2mm,φ10mm×1mm,φ21mm×1.5mm等。工件长度为5～84mm,不同长度共有15种之多,而且产量大。原采用钢管在车床上切断的工艺方法进行生产,工效低,成本高,为了解决以上矛盾,设计研制了一副多工位的连续冲模,采用在冲床上进行冲压成形的新工艺,从而提高工效近十倍,满足了生产的需要,并大大降低了成本,达到提高经济效益的目的。
Hongling 24 bicycles and Hongling 50 dual-purpose vehicles, need to produce a variety of different diameters of the tubular casing jacket diameter: φ14mm × 2mm, φ18mm × 2mm, φ10mm × 1mm, φ21mm × 1.5mm and so on. Workpiece length of 5 ~ 84mm, a total of 15 different lengths as much, and the yield. In order to solve the above contradiction, a multi-station continuous die was designed and developed, and a new process of press forming on the punch press was used to improve work efficiency Nearly ten times, to meet the needs of production, and greatly reduce costs and achieve the purpose of improving economic efficiency.
