SU393058A1 - BUNKER FOR SUPPLY TRANSVERSE BARS ON AUTOMATIC LINE FOR WELDING NETS - Google Patents

Description

one

The invention relates to the field of engineering, in particular to an automatic line for welding nets.

A known hopper for supplying transverse rods to an automatic line for welding nets, comprising a body made in the form of parallel walls fastened together with a slotted gap, provided with a cutting mechanism and driven grippers for feeding rods under the electrodes of the welding mask.

The proposed bunker differs from the well-known fact that on one side of the body there are pushers entering the slit gap, controlled by pneumatic cylinders placed on the body, which rods are kinematically connected with two fixing bars, on the opposite side of the body grippers for supplying rods for welding machine electrodes are mounted , and in the middle part of the housing there are grooves interacting with clamping cams installed with the possibility of reciprocating movement.

This makes it possible to increase the productivity of the automatic line in the fabrication of fine wire meshes.

FIG. 1 shows the proposed transverse bar feed hopper; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The hopper includes a housing 1, grips 2 for feeding the wire from the hopper under the electrodes of the welding machine, scissors 3 for cutting the wire fed into the hopper, mechanism 4

wire feed with correct device and unwinding device 5.

The body / consists of the front 6 and rear 7 walls, fastened together with a gap necessary for free passage of the wire.

The hopper feed chamber is bounded by an insert 8, fixedly mounted in the groove of the rear wall, and strips 9, pressed against the front wall of the springs 10. At the entrance to

the loading chamber is located dies /, which are simultaneously knives. The slats 9 are connected by studs 12 with a bracket 13, the roller 14 of which slides along the rod 15 of the pneumatic cylinder 16. By means of a bracket 17 rigidly connected to the rod 15, the pushers 18 are hinged.

The intermediate chamber of the hopper is limited by the bottom bar 9 and the cams 19, their protrusions entering the wall grooves and located on the shaft 20 driven by the pneumatic cylinder 21. The cams 19 rotate around the axis 22 and are fixed by springs 23.

The storage chamber is limited to cams 19 and grippers 2 located on the feed mechanism. On the front wall 6 are located the clamps 24, the fixing rods under the electrodes of the welding machine. Works bunker as follows. Wire from the coils located in the unwinding devices 5, the rollers 25 and 26 of the feed mechanism 4 are fed through the nozzles 11 into the hopper feed chamber. The predetermined length of the wire fed into the loading chamber is determined by the feed mechanism. A piece of this wire is driven by the dies 11 and the knife 27 when shears 3 are triggered. As soon as the scissors 3 cut the wire, the pneumatic cylinders 16 work. When moving down, the rods 15 with their projections press the rollers 14. The slats 9 retract into the back wall 7 and open pusher passage 18. The latter push the wire into the intermediate chamber. The wires are pressed between the pushers 18 and the cams 19. The pneumatic cylinder 21 operates. The cams 19, when turning the shaft 20, rise up and turn around the axis 22, intercepting the wires. The pneumatic cylinder 21 is turned off, and the cams 19 are returned to their original position, and the wire is under the cams in the accumulation chamber. The pneumatic cylinder 16 is turned off and the pushers 18 are returned to their original position. Repeated cycle begins. Since the rods under their own weight do not fall into the grippers 2, the magazine is pre-filled with wires to level I-I. In this case, the wires are forcedly pressed by the cams 19 due to the force of the pneumatic cylinder a 21. The first bar is in the grooves of the grippers 2, with which the bar is fed under the electrodes of the welding maschine, which is held by the clips 24 until the end of the welding cycle. As the nolokas are consumed from the bunker, a command is sent from the limit switch that controls the level of the wires in the bunker to feed the wire into the loading chamber. The number of wires that are simultaneously loaded should be such that the time taken to iodine the wires from the bay into the storage chamber is less than the time spent issuing the same amount of wires from the bunker. Object of the Invention A bunker for supplying transverse rods to an automatic line for welding nets, comprising a body made in the form of parallel walls fastened together with a gap gap, equipped with a cutting mechanism and driven grippers for feeding rods under the electrodes of a welding machine, characterized in that In order to increase the productivity of the automatic line in the manufacture of cejoK from thin wire, on one side of the body there are installed pushers that are included in the gap gap and are located on the body. cylinders with brushes kinematically connected with two fixing flanges, on the opposite side of the case, clamps are mounted to feed the rods under the electrodes of the welding mask, and grooves are made in the middle part of the case, which are installed with reciprocating movement.
