【正文】 ery procedures should be added.5) Waste, such as continuous, should increase the cutting process, using waste cutter cut. Automatic press itself, as some waste cutter, you do not have to die to consider.6) Can be countersunk head hole punching. Figure7—78 shows the first hole punching of the workpiece . When clamping the punch die Xiaoping Tou both plane and concave hole stretch of artificial parts, and contact with each other in order to prevent inward deformation of holes. Clamping direction due to the strict size requirements, so the punch assembly when subject to a high degree of repair potential. Also can be used as shown in Figure 779 height adjustment body punch. The upper punch 3 face, contact with the slider 2. Slider righthand side has opened a Tshaped slot to acmodate the screw 5 in the head. Rotating screw 5, then move along the slider 2. As the slider 2 and the mold base 4 in order to ramp contact with each other, while the punch 3 in the fixed plate is sliding in with l, consequent punch in the direction of the location of mold can be adjusted. Adjusted with the nut 6 fixed. Figure778 Stamp shen head hole1—Convex Die 2 Die Figure779 Punch height adjustment body1 Fixed Plate 2Slider 3 Punch 4 On the mold base 5 Screw 6 Nut 7) There are strict requirements of local relative position within the shape, should consider the possibility of the same station on the out, in order to maintain accuracy. If there are really difficult to be broken down into two working bits. Be better placed in two adjacent stations. Third, the principle of stamping operations sequencing 1)For pure blanking progressive dies, in principle, the first ,punch,
