摘要:
Specially designed to form an element that is easy and fast to install, with a long useful life and which improves the expulsion of residues after stamping, the counter-die of the invention is composed of a tubular body, divided into several parts (1-1'-1") and joined to each other by tongue and groove joints using twisted edges (2) at the ends, preferentially three parts, these having an inner sector (3) which is the largest, of injected plastic, very resistant and light, over the exterior surface of which there is a coating (4) of polyurethane. The parts are joined to each other by orifices and grooves in their ends, more specifically in the area made of injected plastic, through which the respective rods or pins (11) pass.

The device comprises a path for the web material (N) and, along said path, at least one cutting unit (7A). The cutting unit comprises: a plurality of intermediate disk-shaped blades (9A) disposed on one side of the feed path of the material, which can be positioned transversely to the direction of feed and cooperating with a fixed counter-blade (33A) disposed on the opposite side of said path. Also provided are two lateral disk-shaped blades (10A) to cut the trimmings; and a member for transverse positioning of the blades. The two lateral blades each cooperate with a respective movable counter-blade (71A), separate from the fixed counter-blade, which can be positioned transversely to the direction of feed of the web material.
摘要:
Die Erfindung betrifft ein Verfahren zur Aufteilung einer kontinuierlich hergestellten metallkaschierten Laminatbahn (13) kommisionsweise in einzelne Platten (15) in beliebiger Grösse mittels Rechnereinsatz und einer Säge. Die zugehörige Vorrichtung besteht aus einer durch den Rechner bahngesteuerten NC-Säge (14), deren im Sägekopf (47) befindliches Sägeblatt (31) entlang den Schnittkanten eine Seitenabstützung besitzt. Diese Seitenabstüztung enthält Schneidenplättchen (37a,b), die mit einer Seitenfläche unter leichtem Druck an das Sägeblatt (31) angelegt sind und mit einer weiteren schmalen Kantenfläche die Schnittkante auf der metallkaschierten Laminatbahn (13) abstützten. Zur Besäumung des drucklos ausgehärteten Pressrandes sind vor dem Sägekopf am Rande der metallkaschierten Laminatbahn feststehende Kreissägen mit einer Seitenabstützung des Sägeblatts angeordnet.
摘要:
Mécanisme compact de couteau dans une imprimante, servant à découper une bande d'enregistrement (30) lorsque le mécanisme se déplace avec une tête imprimante. Le mécanisme comprend un organe rotatif de coupe (68), permettant de couper entièrement ou partiellement la bande (30) dans les deux sens de défilement de la tête imprimante. L'organe rotatif de coupe (68) est monté sur un goujon (58) dont l'extrémité inférieure est sollicitée par un ressort (70) contre un organe de came (80). L'organe de coupe (68) se déplace d'une position non coupante vers une position de coupe sous la commande d'un solénoïde (36), et pendant ce mouvement l'extrémité inférieure du goujon glisse sur une surface d'appui inclinée de l'organe de came (80), de manière à guider l'organe de coupe (68), qui s'engage avec une partie de bord (98) d'un organe de couteau (94) agissant de concert.
摘要:
To adapt a punch press to cut work blanks, a cutting mechanism having a freely rotating cutting wheel (72) is provided to a first support of the punch press while a corresponding die (62) having a groove for mating with the cutting wheel is provided to a second support of the punch press. To operate, the cutting wheel (72) is moved toward the die a given distance such that the cutting edge of the cutting wheel (72) slidably mates with the cutting edge (74a, 78a) of the groove of the die to effect cutting of the workpiece. By synchronously rotating both the cutting wheel (72) and the die (62) to different orientations while maintaining their respective cutting edges aligned and in sliding contact with each other, and by moving a worksheet relative to the cutter wheel (72) and die (62), a multidirectional path may be effected on the worksheet.
