160 Sheet metal forming and blanking mally a hydraulic one. The top die is attached to the slide. The lower die is mounted on the press bed with the blank holder. The punch is located in an opening in the center of the press bed on the draw cushion. During deformation, the blankholding force is transferred via the slide from above and the draw punch force acts from below through the mounting area, die slide e ector draw punch press bed draw cushion slide stroke Fig. 4.2.3 Single-action die with draw cushion slide die blank holder pressure pins Metal Forming Handbook / Schuler (c) Springer-Verlag Berlin Heidelberg 1998 3 part height
Deep drawing and stretch drawing active draw cushion. The punch forms the part by means of its upward movement while the blank holder rests on the die. The active counter drawing combines the advantages of static blankholding and the low power usage of double-action dies with the advantage of a single-action die, in which it is not necessary to rotate the part. Admittedly, it is necessary to have a special modification of the dies for performing this operation, since the forces operate in the opposite direction to those of a normal single-action deep drawing press with draw cushion. Thus, these dies cannot be installed in a normal single-action press. mountingarea, die blank draw cushion press bed slidestroke slide e ector die blankholder active draw cushion Fig. 4.2.4 Counter drawing die/reverse drawing die Metal Forming Handbook / Schuler (c) Springer-Verlag Berlin Heidelberg 1998 3 part height draw cushion stroke 161
