Abstract : the calculation of bending force, is an important designing work in sheet metal. it influences the choosing of equipment tonnage, die material selection and the life span of a die. in the article, a method for calculating the sidepushing force acted on a punch is given out
文摘:彎曲力的計算在板料沖壓中是一個重要的設計工作，影響著設備噸位、模具材料及其使用壽命，介紹了一種計算彎曲凸模所受側推力的計算方法。 -
Based on the above algorithm, a preprocessing software system special for computer simulation of sheet metal forming processes has been developed. for giving cad model of tool surfaces, the algorithm provided in this paper can fully automatically generate quadrilateral finite element meshes from nc track points of tool surfaces, which include the punch, the blank holder, the blank and the die
對于給定的cad模型，本文通過cam數控編程獲得的nc軌跡，能夠自動生成沖頭、壓邊圈、板料和凹模的全四邊形網格，避免了基於cad模型網格生成演算法通常所需的幾何修復時間，大大提高了cae建模效率，降低了建模勞動強度。 -
In sheet metal, drawing is a process of forming flat sheet metal into hollow shapes by means of a punch that causes the metal to flow into the die cavity
在鈑金中，制圖的過程，就是將一個平鈑金沖壓成凹狀，通過一個沖孔使金屬流入型腔。 -
