Abstract
A blanking die apparatus includes a first blanking die including an upper die shoe including an upper die shoe cutting surface and a lower die shoe including a lower die shoe cutting surface. A second blanking die including an upper die shoe including an upper die shoe cutting surface and a lower die shoe including a lower die shoe cutting surface. An infeed assembly that is configured to form a continuous strip of a metal sheet into a non-planar, arc-shape as the continuous strip of metal sheet enters the first blanking die.
Claims5
A blanking die apparatus comprising:
- a first blanking die comprising an upper die shoe including an upper die shoe cutting surface and a lower die shoe including a lower die shoe cutting surface;
- a second blanking die comprising an upper die shoe including an upper die shoe cutting surface and a lower die shoe comprising a lower die shoe cutting surface;
- and
- an infeed assembly configured to form a continuous strip of a metal sheet into a non-planar, arc-shape in a cross-feed direction as the continuous strip of metal sheet enters the first blanking die;
- wherein the infeed assembly comprises multiple shaping members having gaps located in the arc-shape in the cross-feed direction that receive the continuous strip of the metal sheet, the first and second blanking dies cooperate to cut a first metal blank that travels in the cross-feed direction along a ramp between the first and second blanking dies and a second metal blank that travels along another ramp in a feed direction from the second die.
