鈑金類產品設計的基本原則

發布時間:2023-12-04

我們經常用到的五金類零件中常用的金屬材料有不銹鋼、銅、鋁、 鋅合金、鎂合金、鋼、鐵等。

五金制品根據加工方式不同常分為冷加工及熱加工類,不同種類的五金成型方法也不一樣,冷加工類如鈑金類材料,主要是通過模具冷沖壓、折彎、拉深等工藝成型。熱加工類如鑄造類零件,主要通過將五金原材料熔化成液態用模具鑄造而成。

一般認為,凡是厚度均勻的片材類金屬材料統稱鈑金。常用的鈑金材料有不銹鋼、鍍鋅鋼板、馬口鐵、銅、鋁、鐵等。

產品厚度均勻的原則

鈑金就是厚度均勻的材料,在結構設計時應該要注意,尤其是在折彎比較多的地方,很容易造成厚度不均勻。

易于展平的原則

鈑金件產品是由片材加工而成的,在沒有加工之前,原材料是平整的,所以,在設計鈑金件時,所有折彎及斜面都要能展開在同一個平面上,相互之間不能有干涉。
