Abstract

Usage: for welding flat grids on various welding machines. SUMMARY OF THE INVENTION: a line comprises a bay, wire holders, a multi-spot welding machine, a cross wire feed device, shears for cutting transverse and longitudinal wires, a device for clamping the latter, a direct-dumping device and containers for finished nets. The device for clamping the longitudinal and transverse wires is made in the form of interconnected lower and upper traverses, the latter being installed with the possibility of reverse-reverse movement perpendicular to the plane of the base. The device for clamping the longitudinal and transverse wires also contains two wires separately mounted on the upper crosshead, and on the lower - along the entire length of the mesh, clamps. The grip for the transverse wire is made in the form of sliders mounted with the possibility of adjusting movement along the feed axis of the transverse wire, L-shaped plates fixed on the sliders and mounted on the L-shaped plates with the possibility of counter-directional rotation of the clamping elements connected between themselves by means of an adjustable springs. 4-yl. ::.

Description

. FIELD OF THE INVENTION This invention relates to a technique for welding flat screens on various welding machines. .

The purpose of the invention is to increase productivity and increase the speed of welding of the intersection points of the wires to the limit value.

In FIG. 1 shows the main line, in FIG. 2 is a plan view, in FIG. 3 is a view A, in FIG. 4 a section bB.

An automatic line for welding flat grids (Figs. 1-4) consists of coils 1 with a wire wound around their coils, pneumatic cylinders 2 with a device 3 for feeding longitudinal wires 4, consisting of interconnected earrings 5 of the upper crossbar b having the possibility of reciprocal radial movement perpendicular to the plane of the base from the actuator 7 and having BT-shaped grooves secured separately sprung toothed jaws 8 for clamping at least two longitudinal wires 4, and the lower traverse 9 with teeth with sponges 8 along the entire length of the mesh with movable guide dies 10 attached to it and grippers 11 moved by sliders along the dovetail 12 of the fpaaepCH 9 and made in the form of mounted with the possibility of adjusting movement along the wire feed cross wire

connected by a compression spring 13 and attached to the L-shaped plates with installation on the L-shaped plates with the possibility of counter-directional rotation of the clamping elements 14 and 15 by means of axes 16c with adjusting bolts additionally, further, a welding multi-point machine 17 with upper 18 and lower 19 electrodes of the known device 20 for feeding the transverse wire 21 into the grippers 11, consisting of a bay 1 with a transverse wire 21, straightening rollers 22 and a drive 23 with a measuring and cutting device, pneumatic shears 24 pieces of mesh 25, receiving and erasing the bending device 26 and the container 27 for receiving the nets 25 per stack, as well as other known auxiliary equipment for servicing the operation of the automatic line.

An automatic line for welding flat grids (Figs. 1-4) after adjusting the nodes and distributing the wires 4 and 21 along the steps of the grid 25 with leading the ends under the electrodes 18, 19 of the welding machine 17 operates as follows.

At the moment of compression and welding of the points of intersection of the longitudinal wires 4 with the transverse wire 21, the actuators 2 backward return the device 3 to the right starting position, while the clamping elements 14 and 15 of the gripper 11 are opened and released from the transverse wire 21 by the springs 13 and the axis 16 By adjusting the force of the springs 13, it is possible to achieve a small effort of the connector of the clamping elements 14 and 15 and thereby avoid a wave in the transverse wire 21 between the adjacent vertical axes of the electrodes 18 and 19. At the same time, the transverse the wire 21 by the device 20 into the receiving holes of the clamping elements 14 and 15 with its length and after the upper electrodes 18. The pneumatic cylinders 2 feed forward and left the device 3, which simultaneously feeds longitudinal wires 4 and transverse wire 21 under the electrodes 18.19 of the welding machine 17 s the next cycle of welding of the intersection points of the wires 4 and 21 of the mesh 25, passing between the knives of the pneumatic shears 24 and sliding on the receiving corners of the receiving-throwing device 26.

After welding the required length of the mesh 25, it is cut off with pneumatic shears 24 and the device 26 is dumped into the receiving container 27, the automatic line runs continuously, and in the case of the termination of wire 4 or 21 in the coils of the bay holders 1 they are replaced with new ones, like the container 27 when filling its nets 25.
