西安不鏽鋼板的折彎特性

1、因導熱性比普通低碳鋼差,延伸率低,導致所需變形力大;

2、不鏽鋼板料在折彎時與碳鋼相比有強烈的回彈傾向;

3、不鏽鋼板相對於碳鋼由於延伸率低, 折彎時工件折彎角R要大於碳鋼,否則有出現裂紋的可能;

4、由於不鏽鋼板硬度高,冷作硬化效應顯著因此在選擇壓彎刀具時要選擇熱處理硬度應達到60HRC以上的工具鋼, 其表麵粗糙度要比碳鋼的壓彎刀具高一個數量級。

西安不鏽鋼板的折彎特性,一般來說:

1、單位尺寸下,板材越厚,所需折彎力越大,而且隨著板厚增大在選擇折彎設備時折彎力的裕量應該更大;

2、單位尺寸下,抗拉強度越大,延伸率越小,所需折彎力越大,折彎角應該越大;

3、設計圖中板厚與折彎半徑對應情況下,根據經驗,一道彎工件的展開尺寸為直角邊相加減去兩個板厚,完全可以滿足設計精度要求,根據經驗公式計 算展開量可簡化計算過程大大提高生產效率;

4、材質的屈服強度越大,彈性 回複量就越大,為獲得折彎件90度的角度,所需壓刀的角度就要設計的越小。相對於碳鋼相同板厚的不鏽鋼折彎角較大,這一點應特別注意否則會出現壓彎裂紋,影響工件強度。

企业至成立以來,以誠信、合作、雙贏、發展為經營宗旨,堅持價格最優、用戶、信譽的營銷理念,在市場上獲得了良好的口碑。
