According to some embodiments, an abrasive disc punch comprises: a bottom plate; a top plate parallel to the bottom plate and coupled to the bottom plate via guide pins; springs coupled between the bottom plate and the top plate; a punch coupled to the top plate; and a cutting block coupled to the bottom plate. The cutting block comprises a cutting edge that is aligned coaxially with the punch. The abrasive disc punch further comprises a trim cushion coupled to the cutting block via a spring. The trim cushion is positioned within the cutting edge of the cutting block and comprises a flat horizontal top portion. In an open position the two or more springs separate the top plate and punch from the bottom plate and the cutting block, and the flat horizontal top portion of the trim cushion is positioned above the cutting edge of the cutting block.

The present invention relates to an advance shaft transition apparatus for sheet processing equipment, which comprising: a plurality of advance shafts for feeding foils, the plurality of advance shafts being arranged along a horizontal direction; an advance shaft supporting frame, the advance shaft supporting frame supporting the ends of the advance shafts so that the advance shafts can freely rotate; and a lifting means, the lifting means is provided with a driving means and a transmission mechanism, the lifting means is connected to the advance shaft supporting frame to enable the advance shafts to move between a first position and a second position, at the first position, the advance shafts is operably rotated to feed the foil, and at the second position, the advance shafts being lifted up from the first position to leave a position where the foil can be fed.

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 includes an upper die shoe including an upper die shoe cutting surface and a lower die shoe comprising a lower die shoe cutting surface. The second blanking die movable on a base in a feed direction to increase and decrease a dimension of a blank formed between the first blanking die and the second blanking die.

The present invention relates to a die cutting insert comprising a punch shoe having an angled guide surface. The die cutting assembly further comprises a trim punch arranged at least partly along the angled guide surface, such that the trim punch is movable along the angled guide surface between a first, extended position and a second, retracted position. In further aspects, the invention relates to a die cutting assembly and a method of cutting sheet metals.

Various embodiments disclosed in the present document relate to an accessory and a manufacturing method therefor. Various embodiments disclosed in the present document may provide an accessory comprising: a base structure which comprises a plate having a front surface facing in a first direction and a rear surface facing in a second direction opposite to the first direction, and a side member extending from the edge of the plate; a first cover member which at least partially covers the surface, including the rear surface, of the base structure and comprises a first flat portion placed opposite to the rear surface, a first edge portion placed opposite to the outer surface of the side member, and a first hemming portion placed opposite to at least a part of the inner surface of the side member; and a second cover member which at least partially covers the surface, including the front surface, of the base structure and comprises a second flat portion placed opposite to the front surface, and a second edge portion placed opposite to at least a part of the inner surface of the side member, wherein at least a part of the second edge portion overlaps at least a part of the first hemming portion.

The invention relates to an apparatus comprising a separating tool and comprising a counterpressure plate for producing contour geometries adhesive-containing composite materials, wherein the separating tool can be moved in translational tool stroke directions between an inoperative position and a parting position normal to the counterpressure plate, and also to a method for producing contour geometries in adhesive-containing composite materials by means of an apparatus of this kind. The separating tool and the counterpressure plate f can be actuated relative to one another by means of at least one actuator in at least one excitation direction with a ramp function and/or with a jump function. Each of these excitation directions lies in a parallel plane to a cutting edge plane of the separating tool. The present invention permits reliable separation of a stamped grid from laminate sections which remain on a carrier film.

A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

A clamshell die press includes a fixed platen, a moving platen installed thereon a cutting blade, and a pad mounted on top of a working surface of the fixed platen, wherein the pad comprises a padding block, wherein the padding block comprises a padding layer composed of a material selected to match a tooth profile of the cutting blade.
