Deep drawing characteristics of hemispherical and parabolic metal stamping parts

Stamping parts processing manufacturers process metal stamping parts, metal stamping parts, furniture hardware accessories, etc., customized by drawings! Today, let’s take a look at the deep drawing characteristics of hemispherical and parabolic metal stamping parts in special stamping parts? 1. The drawing characteristic of hemispherical and parabolic stamping parts is that at the beginning of drawing, the punch and the middle part of the blank have only one point of contact; the drawing of hemispherical metal stamping parts requires only one drawing because the drawing coefficient is constant. deep. The drawing method is as follows. a. When t/D>3%, it can be drawn without a blank holder, but the parts must be corrected at the end of the stroke. b. When t/Du003d0.5%～3%, a blank holder or reverse drawing method is required. c. When t/D<0.5%, a concave die with drawing ribs or reverse drawing is required. deep. d. When drawing large-size thin spherical metal stamping parts, the die with deep drawing ribs and the blank holder can be used without the drawing method of positive and negative drawing at one time. 2. Parabolic hardware Drawing of stamping parts 1. Shallow parabolic metal stamping parts (h/d<0.6), the drawing characteristics are similar to hemispherical parts, so the drawing method is similar to that of hemispherical parts. 2. Deep parabolic metal stamping parts (h/d>0.6) generally require multiple deep drawing or reverse drawing.
