Description

This invention relates to machines for producing a honeycomb set of metal strips, which are molded and welded together by resistance welding using toothed rollers.

The known machines of this kind do not provide high productivity, since the welding of the molded strips is carried out with the help of an additional roller moving in the transverse direction. To eliminate this drawback, it is proposed to supply the machine with two pairs of engaged gear rollers, of which the driving roller is steel and the driven roller is from copper alloy, both of which are made of copper alloy and connected to a source of welding current for contact welding. corrugated strips of cellular tape.

To obtain a honeycomb set of several honeycomb belts, the maschine is provided with stops and a knife with a drive for measuring and trimming the honeycomb tape, as well as mechanically driven roller pliers for welding the trimmed honeycomb tape into the honeycomb kit.

FIG. 1 shows the proposed vehicle, side view; in fig. 2 - welding tongs rollers in axial section.

Between the two metal cheeks 1 there are two rolls 2 of a tape blank secured to the holders 3. The tape 4 is unrolled from these rolls in the form of two strips passes through a punching plug consisting of a matrix 5, a clamp 6 and a punch 7, which is under the influence of a spring 8 and the cam 9. The deflecting roller 10 directs the mite to the compensating roller 11, the axis of which is in the slot 12 and is pulled by the spring to the left. When exiting the guide rollers 13 and 14, the belt blank is fed to the driving gear rollers 15 and 16, as well as to the driven gear rollers 17 and 18.

The rollers 15 and 16 are made of steel and serve to groove the tape, and the rollers 17 and 18 are made of copper alloy, attached to a source of welding current and weld the grooved workpieces together with the B honeycomb tape. After welding, the honeycomb tape enters the podgo

a holding arm 19 provided with a spring 20. The lugs 21 and 22 serve to measure the cellular tape, and the movable knife 23 reciprocating cuts the tape. The pusher 24 moves the segments of the cellular tape down, where they are welded together by welding tongs with toothed rollers. The rollers 25 serve to strip the welding rollers 17 and 18. The rollers 26 and 27 of the welding tongs are located at an angle to one another and have teeth, whose slope is equal to the gap between the cells of the cellular tape. These rollers 26 and 27 receive, respectively, rotation from gears 28 vi 29 to move progressively from screw 30 along guide rails 31 and 32. Spring 33 creates pressure on the rollers during welding.

The insulating disc 34 prevents the rollers from closing. When welding rollers make translational and rotational movement. The teeth of the rollers go into the holes of the honeycomb tape and weld the tape segments into the honeycomb set of the required sizes. The manufacturing process of the honeycomb kit is fully mechanized and is carried out continuously.
