后盖板(见图1)是车灯开关上的一个零件,材料为0.8钢板、厚度0.8mm。由于该零件的弯曲方向互相垂直,成形这种零件一般需用两副弯曲模来加工。我们用聚氨酯橡胶做弹性元件,设计制造了一副纵横向弯曲一次成形模将该零件一次弯曲成形。经生产证明,此模具不仅结构简单、操作方便,而且工件质量稳定、生产效率高。 Rear cover (see Figure 1) is a part of the light switch, the material is 0.8 steel, the thickness of 0.8mm. Since the parts are bent perpendicular to each other, forming such parts generally requires two bending dies to be machined. We use polyurethane rubber as the elastic element, designed and manufactured a vertical and horizontal bending once the forming mold to bend the shape of the part. The production proved that this mold is not only simple structure, easy operation, and the workpiece quality and production efficiency.
