弯曲件工序的合理安排,应根据零件形状的复杂程度、精度要求的高低、生产批量的大小及材料性能等因素进行考虑。如果工序安排合理,可减少工序,简化模具设计,提高产品质量,提高生产效率;反之,工件质量低,废品率高。 图中所示为4102、02、61柴油机油尺支承板,其原加工工艺是:切料→落料→冲孔→一次弯曲→二次弯曲→镀锌钝化。但是,此工件在冲孔后,以 Reasonable arrangements of the bending process should be based on the complexity of the shape of parts, the level of precision requirements, the size of the production batch and material properties and other factors to be considered. If the process is reasonable, can reduce the process, simplify the mold design, improve product quality, improve production efficiency; the other hand, the workpiece quality is low, the rejection rate is high. The figure shows the 4102,02,61 Diesel oil dipstick support plate, the original processing technology is: cutting → blanking → punching → a bend → secondary bending → galvanized passivation. However, the workpiece after punching, with
