Stanzmaschine mit ein- und auswechselbarem Stanzwerkzeug und mit einem Werkstückvorschub

摘要

In order to make it possible to speed up the tool change on a stamping machine and, in a preferred manner, also perform it fully automatically via the numerical control of the stamping machine, the work feed motion is used for at least part of the tool-change operation. For this purpose, the punching tools (5), which are each situated on a holder (13), can be arranged in a row on the supporting rail (23), or the supporting rail can be used in conjunction with a magazine (34, 35) as part of the tool-change device. In the latter case, a displaceable transfer and supporting arm (38) or a swivellable transfer or supporting arm (43) is inserted between one end of the supporting rail and the magazine. The work table (18) must be of corresponding design to ensure that the tool-change motion of the holder (13) into the tool-holding fixture (3) of the stamping machine and vice versa is not hindered. It can be either of two-part design or is provided with a slot. A sectional table is also suitable. ……
