5A/250V、10A/250V插孔零件(图1)批量大,种类多,中心孔大小不一。历来我厂都采用三次弯曲成型:第一弯“U”型,第二弯“O”,第三弯“L”型。共用三副模具,工效低,劳动强度大,精度差,不安全。根据零件特点,我们设计了一副弹压结构弯模,在一次冲程内连续完成几个变形动作,同时完成自动脱料。经短期运用证明,该模具具有操作安全、生产效率高、弯曲精度好等优点,并特别适用于大批量生产。 5A / 250V, 10A / 250V jack parts (Figure 1) Large batch, variety, the center hole size varies. Traditionally, I have used three bending molding plant: the first bend “U” type, the second bend “O”, the third bend “L” type. Three common mold, low efficiency, labor-intensive, poor precision, unsafe. According to the characteristics of the parts, we designed a bending structure of the elastic structure, in a stroke to complete several deformation movements, while completing the automatic strip. The short-term use proved that the mold has the advantages of safe operation, high production efficiency, good bending accuracy, and is particularly suitable for mass production.
