Examples
- In this paper calculation method of complex drawing piece on unfold size is given
本文提出了复杂拉深件展开尺寸的计算方法。 - Usually used as fresh - retaining bag , garbage bag etc , which can be drawn piece by piece
可抽取式彩盒装平口袋,适用于保鲜袋、垃圾袋等 - According to above two calculation method , different type drawing piece results are obtained , automobile install pull valve for example , is used by this calculation method , it is very useful to practice press production . ideal workpiece is on assemble obtained
利用上述两种计算方法得到的不同类型的拉深结果,应用于实际冲压生产,如汽车制动阀安装板,获得了较理想的装配要求。 - First calculation method : doing horizontal projection drawing on drawing piece , k value is introduced by area equation of projection drawing , k value is obtained by area equation , along outline of projection drawing to add k value , that is , outline shape of blank drawing , principle area - equal and shape similar are used . second calculation method : along outline of drawing piece horizontal projection drawing , to do normal line of penetration line for wantonly point of this point , to obtain high of drawing piece on this point normal line , point and point is to form outline shape of blank
计算方法之一为k值法:作拉深件水平投影图,在该投影图面积方程中引入k值,利用面积相等原理解方程,求得k值,沿水平投影外沿加上k值,即为毛坯图的外廓形状。计算方法之二为拉深线法:沿拉深件水平投影图外廓,在任意点作该点切线的法线,在该法线上以该点拉深件的高度为量,在法线上取截点。 - Drawing piece unfold size is one basic condition under the calculation on coefficient , number of drawing , handbooks or books of press are not given , practice press production , die designer designs drawing die by experience calculation , after testing , according to deformation , state , defect shape of testing blank , shape and unfold size is revising , finally , unfold size and shape of blank are determined , designing period is longer , cost of die and work piece is to raise , economic benefit is to reduce
拉深件展开尺寸是拉深可行性分析中计算拉深系数与拉深次数的前提条件,现有冲压手册或教材对于复杂拉深件的展开尺寸计算尚未论述。复杂拉深件的冲压生产中,模具设计者凭经验估计拉深可行性,设计制造拉深模进行反复试压,根据试压件的形变状态,缺陷形貌,制定坯料展开尺寸和形状,周期较长,因而生产成本高,经济效益不佳。
