摘要： The present invention has as its technical problem to provide a punching method able to stably secure a stretch-flangeability equal to or greater than the case of using a punch having a flat blade at its bottom surface. The punching method of the present invention is a method of punching a metal sheet using a punching and shearing device provided with a punch having an upper blade having a horizontal part with respect to the cutting line in part and having parts other than the horizontal part comprised of inclined parts and a die having a lower blade wherein the upper blade used for the punching process has a shape where the inclined parts first contact the metal sheet at the time of a punching process.

摘要： The subject of the invention is a device for simultaneous shearing of two sheet metal blanks comprising, for each sheet metal blank, an assembly formed, on the one hand, by a support member of the corresponding sheet metal blank comprising a rectilinear cutting edge and, on the other hand, by a movable cutter provided with a rectilinear cutting edge designed to interact with the cutting edge of the corresponding support member. The cutting edges of the two support members and cutters assemblies are situated in a same reference plane P and the support members extend on either side of the reference plane P. The invention applies to installations for welding by laser beam of two sheet metal blanks placed edge to edge.

摘要： An arrangement for cutting sheet metal, particularly sheet metal strips. The arrangement includes a double cutting tool with two outer knives and an inner knife which is movable between the outer knives so as to form two cutting gaps. The outer knives are adjustable relative to each other by adjusting wedges in order to adjust the cutting gaps such that the two outer knives are adjusted by the adjusting wedges synchronously or asynchronously by either the same or a different extent. The two outer knives can be clamped against the adjusting wedges.

摘要： The present invention relates to a shear for shearing laminar elements, flat material. This shear comprises at least one pair of blade-holders and associated blades which move substantially parallel to each other along straight lines which are spaced apart a predetermined distance from each other. The predetermined distance is computed as a function of the thickness of the material and the nature of the material which is to be sheared. The blades have cutting edges which, at the time of shearing, apply a pair of mutually perpendicular forces Fx and Fy to the material being sheared. The force Fy acts along a straight line perpendicular to a plane or surface through the material or upon which the material rests. It is along the straight line of the force Fy that the blade-holders and blades move during the shearing operation.
