摘要： Described is a method of producing wire-mesh mats (G) from criss-cross longitudinal (L) and transverse (Q) wires welded together at the crossing points. The longitudinal wires (L) are drawn continuously from a feed into a buffer store (4) from where they are fed further. The longitudinal wires (L) in front of the welding line (X-X) in the welding machine (7) are clamped at their front ends to additional longitudinal wires (L) drawn from the feed through the buffer store (4) and brought into position. All the longitudinal wires (L) are then displaced horizontally, in front of the welding line (X-X), at right angles to their longitudinal axis to give a predetermined spacing, and predetermined longitudinal wires (L) are fed, together with transverse wires (Q), on a cyclic basis, to the welding line and a selectable length cut off from the wire feed. The welded mat (G) is pulled out of the welding machine on a cyclic basis at the same time as the longitudinal wires are fed in and finally stacked.

摘要： A process and plant are disclosed for manufacturing grates made of longitudinal and transverse hot-rolled steel rods which cross one another and are welded together at their crossing points. The billet used to form the longitudinal rods is continuously withdrawn in a device (1) over a spill from a wire storage, stretched to improve its mechanical technological properties, then tempered and cut into sections. The longitudinal rods are then arranged in groups, according to the arrangement of the longitudinal rods in the grate to be produced, are moved into the working region of the grate welding machine (4) and introduced therein. The billet for forming the transverse rods is continuously withdrawn in a device (5) over a spill from a wire storage, stretched to improve its mechanical technological properties, then conveyed through a buffer storage, tempered, then each transverse rod separated from the billet is fed to the grate welding machine in time with the welding cycles.

摘要： Disclosed is a machine for bending rod-shaped material in two directions, comprising a rotable plate (5), fitted with a centrally positioned mandrel (12) and an eccentrically positioned bending tool (13), and a fixed, adjustable holder (15; 17). The plate is mounted coaxial to a housing (1) which is in turn mounted to rotate in a fixed support about an axis (X-X) (4). The plate can be turned by means of a rotary drive (18) mounted on the housing. The holder is positioned eccentrically on the housing and can be brought by means of the rotary drive (18) up against the material to be bent.

摘要： A process is disclosed for generating a sinusoidal, periodically variable welding current with a high power density for a multipoint resistance welding machine powered by a monophase alternating current. The welding current is generated from a three-phase mains voltage source by means of a pulse width modulated current inverter circuit and the frequency of the welding current is set at a higher level than the frequency of the mains voltage source.

摘要： The invention relates to a method and a device for producing wire lattice mats, consisting of longitudinal and transverse wires (L1, L2; Q1) which cross each other and are welded together at the points where they cross by means of welding electrodes, according to the resistance welding technique. Before being welded with the transverse wires, said longitudinal wires are moved together transversally to the advance direction of the longitudinal wires, horizontally in relation to the welding electrodes (19, 20), in selected stages after a predetermined number of welding cycles, and then secured again in the new positions.

摘要： A plant for the continuous production of structural components, consisting of two parallel flat grids of welded longitudinal and transverse wires, from which project straight web rods holding the grids at a predetermined distance apart, and of an insulating body fitted between the grids through which the web rods project, with a production channel (2), on either side of which there are supply reels (3, 3') and guiding devices (5, 5') for edgewise endless grid webs (G, G') and insertion devices (7, 7') to draw the grids off stepwise and feed them into grid guides (14, 14'). There are two cutters (11, 11') in front of the guides to cut off grids (M, M') of predetermined length and the grids can be advanced stepwise in the guides and production channel, with the aid of a grid conveyor (18), to web wire supply and cutting devices (26, 26') and downstream welding stations (30, 30') so that both ends of all the web wires (S) can be simultaneously welded at both ends to corresponding longitudinal wires (L, L') of the grids. Furthermore, an insulating body guide (22) and conveyor (24) advance the insulating bodies stepwise and in synchronism with the grids and a structural component conveyor (32) feeds the structural components stepwise to web wire trimmers (35, 35') and discharges the structural components from the production channel. The insertion devices and all conveyors are coupled together by drive shafts (38, 38') and can be operated together.
