前叉肩罩是自行车前叉的装饰件,如图1所示。该工件材料采用08或08F,厚度为0.6mm带钢。原工件是用短料手工落料再将落料片子用镊子夹进模具而拉伸。落料与拉深分二道工序的生产工艺较落后,劳动强度大,操作时危险,况且前叉肩罩又是装饰件,因此外观要求高,加工难度大。 前叉肩罩自动冲模主要有冲模部分,自动送料部分、自动卷废料三部分组成。 冲模部分由落料,拉深复合一次加工成形,提高生产效率,保证工件加工质量。
Fork Shoulder hood is a bicycle fork decorative pieces, shown in Figure 1. The workpiece material using 08 or 08F, a thickness of 0.6mm strip. The original work piece is hand-blanked with short material then the blanking film with tweezers into the mold and stretch. Blanking and drawing process is divided into two more backward production processes, labor-intensive, dangerous operation, Moreover, the fork shoulder shroud is a decorative piece, so the appearance of high demand, difficult processing. Front fork Shoulder automatic die mainly punching part, automatic feeding part, the automatic roll waste three parts. Die by the blanking part, drawing a deep processing of complex forming, improve production efficiency and ensure the quality of the workpiece processing.
