Abstract

The cutting and bending machine is for use during preparation of reinforcing mats for concrete beams and ceilings. The mats are broken, by first weakening the individual rods within the mats, by mechanical or electrical notching, and then the rods are subsequently broken. All the individual reinforcing rods may be simultaneously separated by impact-, notch-, or heat action. There may be a number of individual cutter blades on the machine, arranged in a line so that the break in the rods form a regular edge to the broken mat.

Description

katten- Trenn- u und Biegemaschine bie Erfindung betrifft die Teilung von Baustahlmatten, die für die Armierung von Betondecken, Betonbalken und Bankette verwendet werden.katten cutting and bending machine bie invention relates to the division of welded wire mesh used for reinforcing concrete ceilings, concrete beams and banquets be used.

Die Baustahlmatten werden von den Drahtwerken in Standartgrössen von 2,'\5 x 5,00 m und 2,15 x 6,00 m gefertigt.The wire mesh is made by the wire mills in standard sizes of 2, 5 x 5.00 m and 2.15 x 6.00 m.

abnehmer dieser Baustahlmatten sind der Eisenhandel und die Bauunternehmungen, die die Baustahmatten auf die am Bau benötigten Größen teilen und auf die vorgeschriebene winklige, u-förmige oder rechteckige Form biegen.The buyers of these welded wire mesh are the iron trade and construction companies, which divide the construction mats to the sizes required for the construction and to the prescribed ones bend angled, u-shaped or rectangular shape.

Es ist bekannt, daß die Baustahlmatten mit Maschinenscheren geschnitten und dann auf einer zweiten Maschine gebogen werden.It is known that welded wire mesh is cut with machine shears and then bent on a second machine.

Es ist außerdem bekannt, daß Biegemaschinen eine maschinell betätige Schere als Zusatzgerät zum Schneiden der Baustahlmattenstücke haben.It is also known that bending machines are mechanically operated Have scissors as an accessory to cut the welded wire mesh pieces.

Der Erfindung liegt die Aufgabe zugrunde 1.) daß das Teilen der Baustahlmatten nicht durch Scheren, sondern durch Brechen erfolgt, ?.) daß statt 2 Maschinen nur 1 Maschine benötigt wird, 3.) daß mit dem gleichen Antriebsmechanismus das Teilen und Biegen erfolgt.The invention is based on the object 1.) that the sharing of the welded wire mesh not by shearing, but by breaking,?.) that instead of 2 machines only 1 machine is required, 3.) that the sharing is done with the same drive mechanism and bending takes place.

Die Drähte der Baustahlmatten sind zwecks Erzielung eines besseren Haftvermögens im Beton gerippt oder eingekerbt. Beim Zienen des Drahtes und infolge seiner Verformung während der Ferting wird das Eisen hart und brüchig, wodurch das Brechen der Stäbe ermöglicht wird.The wires of the welded wire mesh are in order to achieve a better Ribbed or notched adhesion in the concrete. When drawing the wire and as a result Its deformation during ferting makes the iron hard and brittle, which makes the Breaking the rods is made possible.

Die Vorteile der Erfindung liegen darin, daß die Teilung durch brechen einfach irnd zeitsparend ist. werner benötigt maü statt 5 nur Maschine uhd nur einen Antriebsmechanismus, nlage: 2 Die Ausfiilirung der Erfindung ist in anliegender Zeichnung dargeteilt Figur 1 Seitenansicht Figur Grundriß der Trenn- und Biegeeinrichtung Figur 3 Iattenhalter auf BiegebSlken Figur 4 hattenhalter auf Sockel.The advantages of the invention are that the division break through simply and saves time. Werner needs only one machine instead of five Drive mechanism, system: 2 The embodiment of the invention is shown in the attached drawing Figure 1 side view figure floor plan of the separating and bending device Figure 3, lath holder on bending plate Figure 4 had holder on Base.

Die nummerierten Teile sind: 1 Sockel 2 Druckbalken 5 Mattenhalter auf Druckbalken 4 Mattenhalter auf Sockel 5 Biege zapfen kerbeisen bzw. Elektrode 7 Platten 8 Druckhebel Durch Betätigung des Druckhebels ( 8 ) von Hand, durch Motor oder Hydraulik kann sowohl das Trennen als auch das Biegen der Baustahlmatten erfolgen. Für stärkere Baustahlmatten ist eine zusätzliche mechanische oder elektrische Einkerbung ( 6 ) vorgesehen.The numbered parts are: 1 base 2 pressure beams 5 mat holders 4 mat holders on the pressure bar on the base 5 bending tenons kerf or electrode 7 plates 8 pressure lever By actuating the pressure lever (8) by hand, by motor or hydraulics, both cutting and bending of the welded wire mesh can be done. There is an additional mechanical or electrical notch for stronger welded wire mesh (6) provided.
