A metal plate stamping method is provided for cutting a metal plate, on which a bulging portion is formed through stamping, at a cutting area that is defined in a portion other than the bulging portion. The method includes forming a bead on the opposite side of the cutting area from the bulging portion and crushing the bead prior to the cutting of the metal plate.

The invention relates to a bending device for forming corrugations in a metal sheet, comprising: a lower frame; an upper frame able to move vertically between a rest position and a bending position; at least two dies, carried by the lower frame; one being fixed with respect to the lower frame and the other mounted with the ability to slide; at least two punches carried by the upper frame; one being fixed and the other being mounted with the ability to slide on the upper frame; the bending device being designed so that, in operation, as the upper frame moves towards its bending position, the metal sheet transmits a pulling force to the sliding punch and to the sliding die which force moves them from a spaced-apart position toward a close-together position.

A method for preparing a modular planar interconnect plate includes steps of a) providing a metal blank sheet having a main region and two first lateral regions, b) forming two openings respectively in the first lateral regions, and c) stamping to form protrusions and depressions at the main region on lower and upper surfaces of the metal blank sheet. In the stamping step, each of two lower surrounding protrusions and two upper surrounding depressions is formed to surround a corresponding one of the openings, and each of an upper surrounding protrusion and a lower surrounding depression is formed to surround the corresponding ones of the protrusions and depressions formed at the main region and the first lateral regions.

A method is provided for forming a surgical stapler anvil with a first punch having a first plurality of protrusions and an opposing second punch having a second plurality of protrusions. A workpiece having first and second sides is positioned between the first and second punches. The first side is contacted by the first punch, thereby plastically deforming the first side with the first plurality of protrusions to displace material of the first side toward the second side. The second side is contacted by the second punch, thereby plastically deforming the second side to displace material of the second side toward the first side. A plurality of pockets is formed in the first side via the contact of the first punch with the first side and the contact of the second punch with the second side. Each of the pockets is configured to deform a leg of a surgical staple.
