IC697MDL241 

折彎邊不平直，尺寸不穩定

①增加壓線或預折彎工藝

②材料壓料力不夠，增加壓料力

③凸凹模圓角磨損不對稱或折彎受力不均勻，調整凸凹模間隙使之均勻、拋光凸凹模圓角

④高度尺寸不能小于最小極限尺寸

10.彎曲表面擠壓料變薄

①。凹模圓角太小，增大凹模圓角半徑

②。凸凹模間隙過小，修正凸凹模間隙

11.凹形件底部不平

①材料本身不平整，需校平材料

②頂板和材料接觸面積小或頂料力不夠，需調整頂料裝置，增加頂料力

③凹模內無頂料裝置，應增加頂料裝置或校正

④加整形工序

12.不銹鋼翻邊變形

在制造翻邊之前向材料施用優質成形潤滑劑，這能令材料更好地從模具中分離出來，在成形時順暢地在下模表面移動。如此給予材料一個更好的機會去分布被彎曲和被拉伸時產生的應力，防止在成形翻邊孔邊上出現的變形和翻邊孔底部的磨損。
