Title: FORMING AND PUNCHING DEVICE EQUIPPED WITH A MOTORIZED POWER DRIVE IN A STRUCTURALLY INTEGRAL MANNER, AND METHOD
Abstract:
The invention relates to a forming and punching device that is equipped with a motorized power drive in a structurally integral manner and is movable together therewith, and to a method for components (17), consisting of metal sheets, for use in body construction in the automotive industry. The forming and punching device is an extremely compact structure in which the punching die (8), forming die (15) and holding-down means (16) are arranged coaxially and so as to be movable in a reciprocating manner in one another, such that, first of all, at a drive (1, 2, 3, 4) of the device, the holding-down means (16) runs ahead and clamps the component peripherally to the die plate (18), then the forming die (15) is activated and, after forming, punching out takes place by way of the punching die (8). The device can be arranged on a robot and can also be moved past close interfering edges.
