Abstract

Mesh welding process and equipment for the prodn. of concrete reinforcing fabrics, using two mesh welding machines arranged face to face. The distance between the welding machines is adjustable for cross wire pitch changes by means of an appropriate drive. A longitudinally adjustable fabric shear is built into the frame of one welding machine. The electrode plane, and hence the cross wire position during welding, is arranged 75 mm or less from the machine frame edge. ADVANTAGE - The proposed arrangement of two mesh welding machines operating face to face allows virtually infinite variation of cross wire pitch.

Description

Bekanntlich werden Betonstahlmatten/Gitter derart hergestellt, indem eine bestimmte Menge Längsdrähte mit den dazugehörigen Querdrähten rechtwinklig miteinander mittels Widerstandsschweißung zu einem Gitter verschweißt werden. Dabei können die Längs- und Querdrahtteilungen unterschiedlich sein.As is known, reinforcing steel mats / grids are produced in such a way that a certain amount of longitudinal wires with the associated transverse wires at right angles are welded together to form a grid by means of resistance welding. The line and cross wire divisions can be different.

Der Vorgang erfolgt heute derart, daß ein zwischen die Widerstandsschweiße­ lektroden zugeführter Querdraht mit den Längsdrähten verschweißt und danach das Gitter um eine bestimmte Querdrahtteilung vorgeschoben wird. Dieser Zyklus wiederholt sich beliebig oft.The process today is such that one between the resistance welds cross wire fed to the electrodes welded to the longitudinal wires and then the grid is advanced by a certain cross wire pitch. This cycle repeats itself any number of times.

Um die Rentabilität einer Fertigungsstraße zu verbessern sind in der Vergan­ genheit die Zyklus/Taktzeiten für das Verschweißen eines Querdrahtes und den Gittervorschub ständig optimiert worden.To improve the profitability of a production line are in the vergan the cycle / cycle times for welding a cross wire and the Grid feed has been constantly optimized.

Danach begann man Schweißmaschinen zu entwickeln, deren bauliche Ausführung der Schweißelektroden es zuläßt, zwei Querdrähte gleichzeitig mit den Längs­ drähten zu verschweißen, was zu extrem hohen Maschinenleistungen führte, aber auch die Baukosten in die Höhe trieb, wobei die erreichbaren Querdrahtabstände aus mechanischen und physikalischen Gründen (Transport von hohen Ampere- Werten) begrenzt sind.Then they started to develop welding machines and their construction The welding electrodes allow two cross wires to run simultaneously with the longitudinal ones wires to weld, which led to extremely high machine performances, however construction costs also rose, with the achievable cross wire spacing for mechanical and physical reasons (transport of high amps Values) are limited.

Um die Maschinenbaukosten in Grenzen zu halten, den physikalischen Bedingungen zu entsprechen und fast beliebige Querdrahtabstände zu erreichen ist nachfol­ gend beschriebene Erfindung gemacht worden.In order to keep the mechanical engineering costs within limits, the physical conditions To comply and to achieve almost any cross wire spacing is as follows invention described has been made.

Fig. 1 zeigt eine Schweißmaschine mit einer einfachen Elektrodenebene und dem Längsdraht-Gitter-Vorschub. Fig. 1 shows a welding machine with a simple electrode level and the line wire grid feed.

Diese Maschine ist so ausgeführt, daß die Elektrodenebene extrem weit zur linken Maschinenrahmenkante gelegt wurde, was ermöglicht, daß eine weitere Schweißmaschine spiegelbildlich dazu, in Längsrichtung mittels geeignetem Antrieb verfahrbar, anbauen kann, s. Fig. 2.This machine is designed so that the electrode plane has been placed extremely far to the left edge of the machine frame, which enables another welding machine to be mounted in mirror image, movable in the longitudinal direction by means of a suitable drive, see. Fig. 2.

Da aber nur ein Längsdrahtvorschub auch für ein Tandemsystem erforderlich ist, das endlos gefertigte Gitter aber in bestimmte Längen abgeschnitten werden muß, ist in der spiegelbildlich angebauten Schweißmaschine anstelle des Längs­ drahtvorschubes die Gitterschere eingebaut, was hinsichtlich Platzbedarf gegenüber der Einfachausführung keinen zusätzlichen Platz erfordert.But since only a line wire feed is also required for a tandem system, the endless grille can be cut into certain lengths must be in the mirror-image welding machine instead of the longitudinal wirefeeder installed the lattice shear, which requires space no additional space is required compared to the simple version.

Der Vorteil einer solchen Anordnung liegt weiterhin darin, daß hiermit auch bestehende Schweißmaschinen nachgerüstet werden können, also die Wirtschaft­ lichkeit für die Peripheriegeräte erheblich verbessert werden kann.The advantage of such an arrangement is that it also existing welding machines can be retrofitted, i.e. the economy ability for peripheral devices can be significantly improved.

Weiterhin kann die spiegelbildlich angeordnete Schweißmaschine bei Wartung oder Reparatur ausreichend weit von der anderen Schweißmaschine verfahren werden.Furthermore, the welding machine can be arranged in mirror image during maintenance or repair sufficiently far from the other welding machine will.
