摘要:
A tabular negative-pressure sheet 3 includes a baseplate 4, a sheet 5 with conduction grooves, a nonwoven cloth lamination outer layer 6, and a surface layer member 7. The baseplate 4 is a member as a base of the tabular negative-pressure sheet 3. In addition, the sheet 5 with conduction grooves is a member disposed on the outer side of the baseplate 4, and on the surface thereof, negative-pressure conduction grooves 8 are formed. In the tabular negative-pressure sheet 3, negative-pressure conduction grooves 8 are formed in a direction substantially perpendicular to a direction in which a strip 2 is threaded so that a negative pressure is generated as far as an end portion of the tabular negative-pressure sheet 3.
摘要:
Phase displacement is applied and controlled between two synchronously running upper and lower magnetic fields of travelling waves in a system for the contactless application of strip tension, wherein the levitation force produced by means of a displaced magnetic field (3) arises from the return force in order to reliably prevent damage to the surface of the strip (4) and to maintain optimum power efficiency, thereby achieving central levitation of the strip (4) and/or the desired position of the strip.

Die Erfindung betrifft Verfahren und Einrichtungen zum Beschleunigen und Abbremsen von Walzgutlängen (W) in Auflaufrollgängen (1, 31, 81) bzw. Auflaufrinnen (91) von Feinstahloder Mitteistahlwalzstraßen nachgeordneten Adjustageanlagen. Dazu sind elektrisch betriebene Linearmotoren (4, 34, 84) in flacher Bauweise oder mit ringförmigem Querschnitt im Auflaufrollgang bzw. den Auflaufrinnen eingesetzt, deren elektromagnetische Kraftwirkung mittels elektrischem Wanderfeld die Walzgutlängen (W) beschleunigt oder abbremst. Die flachen Linearmotoren (4, 34) sowie die ringförmigen Linearmotoren (84) können im Bereich vor und hinter der Teilschere (TS) und im Auflaufrollgang (1, 31, 81) bzw. in Auflaufrinnen (91) vor dem Kühlbett (K) angeordnet werden. Die flachen Linearmotoren (4, 34) werden auch im Bereich des Auflaufrollgangs (1, 31) neben dem Kühlbett (K) oder einlaufseitig vom Kühlbett verwendet. Die Walzgutlängen (W) werden mittels Weichen (90) vom Auflaufrollgang (81) in die Auflaufrinnen (91) umgeleitet.

摘要:
A metal wire feeder device (1) comprising a body (2) presenting a wire braking member (12), one or more pulleys (14, 15) driven by respective motors (16, 17) about which the wire is wound, the wire before reaching a processing machine passing through a compensator member (20) and a tension sensor (25), an electronic control unit (18) being present able to continuously measure said tension value and make it uniform at a predetermined value by acting on a first regulator loop operating on the motors (16, 17) and a second regulator loop operating on the compensator member (20). Said electronic control unit (18) operates automatically in making said tension uniform at the predetermined value, on the basis of the fed wire quantity or of the wire feed velocity.
摘要:
The invention relates to a method and a device for winding metal strips (13) onto a coiling mandrel (4) which is disposed in a coiler shaft (3) and to which the metal strip is fed by a driver (2) encompassing a bottom and a top drive roller (6, 7) in a driver frame (5). A bench (11) is provided below the metal strip (13) for guiding purposes while a strip switch (17) and a swiveling shaft flap (19) are arranged above the metal strip, the shaft flap (19) adjoining the strip switch (17) to the vicinity of the coiling mandrel. In order to regulate the driver (2) in such a way by measuring the strip tension that the strip run allows the metal strip (13) to be coiled into a straight-edged coil (14), the longitudinal tensile strength applied to the metal strip (13) by the driver (2) to control the strip run through the driver is determined by means of a strip tension measuring device (10) which is mounted on the driver frame (5), in a pivot located shortly behind the bottom drive roller (7), and can be swiveled into the metal strip (13) from below. Said strip tension measuring device (10) is composed of a first lever arm (10a) that is mounted in a pivot at the rear of the driver frame (5) as well as a second lever arm (10b) which is hingedly mounted at the front of the first lever arm (10a) and the forward end of which is provided with a roller (23). A force measuring means (24) is placed between the first lever arm (10a) and the second lever arm (10b).
摘要:
The invention relates to a device for guiding elongated metal material, such as wire (D), between a material discharge apparatus (I) and a consumer that draws the material from the material discharge apparatus, comprising a frame for retaining a material-detaching apparatus (3, 4, 5) that can be moved in relation to the consumer, wherein the material-detaching apparatus can be moved linearly and is coupled by means of a rotary element (7, 8, 11) to a restraining element (10) which is preferably formed by one or more springs or hydraulic cylinders.
