Abstract:
Die Erfindung betrifft ein Verfahren zur Erzeugung von Durchgängen in einem metallischen Körper mittels Hochgeschwindigkeitsscherschneiden (HGSS) mit geschlossener Schnittlinie, dadurch gekennzeichnet, dass ein Stempel (1 1 ) mit einer den Durchgängen entsprechenden ersten Abmessung (D) bis zu einer Eintauchtiefe eingebracht wird, bei der der Bruch in Wirkrichtung des Stempels (11 ) durch den gesamten metallischen Körper unter Ausbildung eines Butzens (13) hindurchgeht, dann die Hubbewegung gestoppt und der Stempel (11 ) wieder zurückgezogen wird, und dass in einem Folgeschritt der sich noch im Durchgang befindliche Butzen (13) mittels eines Auswerfers, der eine geringere zweite Abmessung als der Stempel (1 1 ) aufweist, aus dem Durchgang herausgetrieben wird.
Abstract:
An apparatus for cutting a profile, including: a cutter configured to make cuts on the profile having a first surface and a second surface, and having at least one rib on the first surface, wherein the cuts are made on the first surface of the profile; a first drive unit to drive the cutter forward and backward to and from the first surface of the profile; and a second drive unit to drive the cutter up and down along the first surface of the profile.
Abstract:
A cutdown machine (30) and method are disclosed. The cutdown apparatus (30) preferably includes a pair of cutting assemblies (42, 44) for simultaneously cutting the ends of a window covering (10). Additionally, a calculation apparatus (48) and method for use in conjunction with the cutdown machine (30) are also disclosed. The calculation apparatus (48) may be a stand alone unit, or preferably integrated into the cutdown machine (30). The calculation apparatus (48) preferably calculates and automatically positions a stop element (52) in the cutdown machine (30), in connection with desired end window covering dimensions and related stock window covering sizes.
Abstract:
La présente invention concerne un dispositif d'amortissement (2) pour machine-outil (1), destiné à l'absorption de l'énergie en excès lors d'un impact généré dans ladite machine-outil (1), comprenant un bloc de support (4) muni d'un orifice, à l'intérieur duquel peut coulisser au moins un vérin d'amortissement (5) entre une position haute et une position basse, ladite position basse étant atteinte par absorption de ladite énergie en excès, une machine de découpe adiabatique incorporant un tel dispositif d'amortissement et un procédé de découpe séquentielle à très haute cadence de barres métalliques.
Abstract:
A portable apparatus for shearing workpieces has a housing (12) defining an interior (24) to enclose a cutting head assembly (20) during storage. During use, an actuator (38) erects the cutitng head into an operative position and the cover (16) of the housing defines a planar work surface adjacent to the cutting head fixed thereto. The portable apparatus includes a portable power supply (44) for remote operation.
Abstract:
Processing equipment (13) for cutting or shaping all faces of elongate I-section beams (10), girders, tubes or the like, has a plurality of aligned but spaced apart co-axial holding stations (14) on either side of a central processing station (16). Each holding station has a pair of tapered rollers which are both movable towards and away from one another to accommodate I-beams (10) or other elongate bodies (10) of different cross sections. Each holding station (14) can rotate the beam (10) about the longitudinal axis thereof and can also feed the beam (10) through a brush seal (15) into an enclosed water-jet cutting apparatus (16). After processing within the cutting apparatus (16), the support units (14) drive the beam (10) out to a plurality of output support units (17) at the output end (18) of the processing equipment (13). On completion of operations on the beam (10), it can be discharged through the open jaws of the holding stations (14) onto a plurality of output rails (19) for removal.
Abstract:
Method for shearing to size bars, the method using shears comprising a pair of counter-rotating drums (11), the shears comprising a single-channel switching device (14) suitable to cause the rolled stock (13) to transit in correspondence with a shearing zone (20) and a scrapping zone (21), there being included reception means (30, 31) for the bars sheared to size and reception means (28) for the scrapped ends, the blade-bearing drums (11) being maintained in continuous rotation for the whole duration of the shearing cycle, the rotation speed of the blade-bearing drums (11) being made proportionate, on each occasion, to the specific speed of feed of the rolled stock (13) and to the desired base measurement of the bars, the base measurement being a desired shearing length which is a sub-multiple of the length of each bar to be sheared to size, the speed of rotation of the drums (11) being angularly constant and calculated to achieve a finite number of passes of the shearing blades (17) for the specific speed of feed of the rolled stock (13) and for a plurality of specific lengths of the bar (13) which are multiples of the base measurement. Shears for shearing to size rolled bars suitable to achieve the method as described above.
Abstract:
A multiple bar straightening and cutting system in bar steel rolling line, comprising a multiple bar straightening device, an input side guide pinch roller, a multiple running bar cutting device, and a rear tilting table having an output side guide pinch roller, the multiple running bar cutting device further comprising a fixed blade and a movable blade having a plurality of hole shapes suitably matching the cross-sectional shapes of the bar steel and the rear tilting table being tilted in the moving direction of a cutter in synchronous with the movement of the cutter of the multiple running bar cutting device.
Abstract:
