ABSTRACT:
A progressive former having quick-change tooling provides tooling supports with means for adjusting the tools. The tooling is mounted so that the tooling and the structure for adjusting the tooling can be removed as units without loss of the fine-tuning of the adjustments and so that reinstallation does not require readjustment of the tooling. A transfer also provides adjustable cams for opening and closing gripper fingers which transport workpieces from one work station to the next. The adjustable cams are removable with the dies as units and can be reinstalled without further fine-tune adjustment. With the invention, entire tool sets can be changed in a very short time to eliminate loss of production capacity of the machine. Similar sized machines are provided with a fixed spacing between the locating surfaces for the stationary dies and the reciprocating tools so that tool sets having adjustments fine-tuned in one machine can be installed in a similar machine without further retuning of the adjustments.
