Embodiment Construction
[0044] Referring to the accompanying drawings, numeral 10 denotes a machine for forming a welded wire mesh according to the present invention.
[0045]In this example, the welded mesh formed by the machine 10 includes a plurality of longitudinal wires 12 spaced apart from each other, which are welded to corresponding horizontal wires 13, which are also spaced by a predetermined staggered axis.
[0046] This machine essentially includes a frame 11, a plurality of welding heads 15 (in this specific example only for demonstration, two fixed ones are sliding on the frame 11), and a horizontal feed unit (not shown), which A transverse axis 13 may be provided, arranged to fit a welding head 15 .
[0047] Each welding head 15 comprises at least one feeding unit 16 for feeding the longitudinal axis 12 ; a positioning unit 18 capable of keeping the longitudinal axis 12 substantially aligned with the feeding axis X; and a welding unit 17 .
[0048] Each welding head 15 is selectively m...

Welding head for the formation of a metal mesh comprising longitudinal wires (12) and transverse wires (13), comprising at least a feed unit (16) able to feed step-wise a plurality of longitudinal wires (12), and a welding unit (17) by means of which the longitudinal wires (12) are welded to corresponding transverse wires (13). The welding unit (17) comprises at least two electrodes (19, 20) selectively movable between a first feed position, in which at least a first electrode (19) is distant from the transverse (13) and longitudinal (12) wires, and a second welding position, in which both the electrodes (19, 20) contact and grip the wires (12, 13) and apply different tensions in order to weld the wires to each other (12, 13). The welding head comprises at least a movement member (22) operatively associated at least with the first electrode (19) in order to move it between the first and the second position, first sensor members (25) associated with the movement member (22) and configured to detect the position of the first electrode (19) with respect to the two wires (12, 13) and / or second sensor members (30,31) associated with the movement member (22) and conformed to detect the working pressure of the first electrode (19).
Description
technical field [0001] The invention relates to a welding head for use in a machine for producing metal meshes, a corresponding welding method and a machine provided with the welding head. The present invention is preferably applied to, but not limited to, electro-welded metal meshes, which can be used to reinforce reinforced concrete structures. For this reason, in the following description, specific reinforcement is used for this application, but the invention can also be used for other types of web formation. Background technique [0002] Different machines are known for manufacturing electro-welded metal mesh, which is made of a plurality of long wires or circular pieces separated from each other. According to a predefined inter-axis, the corresponding transverse wires or circles are welded perpendicularly to the longitudinal wires. [0003] These machines generally include a plurality of welding heads, at least one for each major axis, and a feed unit to provide the t...
