Abstract

The manually operated tool for cutting sheet metal has two handles (1,2) which are pivoted together. The first handle (1) is connected to the blade (4) which is provided with serrated teeth (4). The second handle (2) is connected to a platform (3) which supports the sheet metal whilst being cut. This type of sheet metal cutting tool prevents the sheet metal from bending whilst being cut and so eliminates the need for a subsequent straightening operation. The narrow strip cut from the main sheet is also free from bending and may be used for other purposes instead of being discarded as scrap. USE/ADVANTAGE - Sheet metal cutting tool which prevents bending of the metal.

Description

Durch die bisher bekannten Blechscheren wird das getrennte Flachmaterial an einer Seite angehoben, aufgebogen bzw. aufgerollt. Hierdurch wird der abgetrennte Teil oft zur Gefahr für Schnittverletzungen.The previously known sheet metal shears make this separate Flat material raised on one side, bent or rolled up. As a result, the separated part often becomes Risk of cuts.

Der in Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, Flachmaterial durch ein einfaches Gerät so zu trennen, daß beide Flächen nach dem Trennvorgang ihre ursprünglich glatte Oberfläche beibehalten.The invention specified in claim 1 is the problem based on flat material using a simple device separate that both surfaces theirs after the separation process originally kept smooth surface.

Mit der Erfindung lassen sich folgende Vorteile erzielen:The following advantages can be achieved with the invention:

  • 1. Mit dem Gerät werden Flachmaterialien durch einen Fugenschnitt getrennt.1. With the device, flat materials are cut through a joint Cut.
  • 2. Das Material bleibt nach dem Trennvorgang vollkommen glatt.2. The material remains completely smooth after the separation process.
  • 3. Es entsteht kein Abfall, da abgetrennte Streifen ohne Nacharbeit weiter verarbeitet werden können.3. There is no waste because there are no separated strips Rework can be processed further.
  • 4. Das Gerät wird durch Hebelkraft bedient und kann daher überall eingesetzt werden.4. The device is operated by leverage and can therefore be used everywhere.
  • 5. Beim Trennvorgang entstehen keine scharfen Schnittkanten und somit auch keine Verletzungsgefahr am Schnittmaterial.5. There are no sharp cutting edges during the cutting process and therefore no risk of injury to the cut material.
  • 6. Das Gerät läßt sich je nach vorgesehenem Einsatz und Materialstärke in verschiedenen Größen herstellen.6. The device can be used and depending on the intended use Produce material thickness in different sizes.

Das Gerät kann aus wenigen Einzelteilen einfach hergestellt werden.The device can be easily made from a few individual parts will.

Das Schneideelement (4) kann als Austauschteil in hochwertigem Stahl in gebogener Sägezahnform oder mit glatter Oberfläche hergestellt werden.The cutting element ( 4 ) can be manufactured as a replacement part in high-quality steel in a curved sawtooth shape or with a smooth surface.

Beschreibung der HandhabungDescription of the handling

Über Hebeldruck wird das zu trennende Flachmaterial durch das Schneideelement (4) von unten an die Halteplatte (3) gedrückt, streifenförmig abgeschert und nach oben aus der Führungsnut (5) des Halteteils gedrückt.The flat material to be separated is pressed by the cutting element ( 4 ) from below onto the holding plate ( 3 ) by means of lever pressure, sheared off in strips and pressed upwards out of the guide groove ( 5 ) of the holding part.

Durch diesen Vorgang wird das Flachmaterial durch eine glatte Schnittfuge getrennt.Through this process, the flat material becomes smooth Kerf separated.

Claims (1)

Schneidezange zum Trennen von Blechen und anderer Flachmaterialien dadurch gekennzeichnet, daß die Zange über Hebelkraft durch ein von unten wirkendes gezahntes Schneideteil das Flachmaterial an eine Gegenplatte drückt, das Material streifenförmig abschert und nach oben durch eine Fuge abführt.
Hierdurch entsteht eine Trennfuge mit stumpfen Kanten ohne Verletzungsgefahr am Schnittmaterial.
Das getrennte Flachmaterial bleibt dabei vollkommen glatt.Cutting pliers for separating metal sheets and other flat materials, characterized in that the pliers press the flat material against a counterplate by lever force through a toothed cutting part acting from below, the material shears off in strips and discharges upwards through a joint.
This creates a parting line with blunt edges without risk of injury to the cut material.
The separated flat material remains completely smooth.
