The essence of the utility model.

A device for perforating thin long workpieces contains a welded base 1 (Fig. 1), on which a guide roller 2 (Fig. 1, 11), a carriage 3 (Fig. 1, 7-9), a frame of the working stand 4 (Fig. 1), the cage pulling 5 (Fig.1, 5, 6). Under the frame of the working stand 4 (figure 1) in the lower part of the base 1 (figure 1) installed freight, replaceable carts 6 (figure 1) for collecting waste. On the frame of the working stand 4 (Fig. 1), there is a tool roll 7 (Fig. 1) and a back-up roll 8 (Fig. 1), which are through gear wheels 9 (Fig. 2) and 10 (Fig. 2) and a coupling 11 (Fig. 2) they receive rotation through a reducer 12 (Fig. 2) mounted on the base 1 (Fig. 1) from the electric motor 13 (Fig. 2) by means of a belt drive 14 (Fig. 2). On the shafts 15 (Fig. 3, 4) of the tool roll 7 (Fig. 1) and the backup roll 8 (Fig. 1), the hubs 16 (Fig. 3) are installed, on which the rings 17 (Fig. 3) with punching punches 18 (figure 4) having cutting edges on the tool roll 7 (figure 1), and on the backup roll 8 (figure 1) are rings 19 (figure 3) with guide rings 20 (figure 3) . Cutting punches 18 (figure 4) is fixed on the hub 16 (figure 3) with screws 21 (figure 4). The number of punching punches 18 (figure 4) and their location is set according to a given perforation card. The hub 16 (Fig. 3) is fixed along the axis of the shaft 15 (Fig. 3, 4) with nuts 22 (Fig. 3) through the bushings (not shown in the drawing) and compensating rings 23 (Fig. 3). Bearing assemblies 24 (FIG. 3) of the tool roll 7 (FIG. 1) and the backup roll 8 (FIG. 1) are installed in the housing 25 (FIG. 3), which is based on the frame of the working stand 4 (FIG. 1). The frame of the working stand 4 (figure 1) consists of a welded base 26 (figure 1), in which four guide columns 27 (figure 1) are installed. Cases 25 (figure 3) of the bearing assemblies 24 (figure 3) of the backup roll 8 (figure 1) are fixed to the base 26 (figure 1) of the frame of the working stand 4 (figure 1). Cases 25 (Fig.3) of the bearing assemblies 24 (Fig.3) of the tool roll 7 (Fig.1) are made with the possibility of movement

along the guide columns 27 (figure 1) from the screw 28 (figure 1) and with the possibility of fixing them on the guide columns 27 (figure 1) with a lock nut 29 (figure 1). On the basis of 26 (Fig. 1), a stripper 30 (Fig. 1) of a tape from the punching punches 18 (Fig. 4) is installed, which does not allow possible tearing of the tape when the punch 18 (Fig. 1) comes out of the tape and additionally presses the processed tape to the support roller 8 (figure 1). Housings 25 (Fig. 3) of the bearing assemblies 24 (Fig. 3) are connected by a crossbeam (not shown in the drawing), on which a waste disposal device is fixed, made in the form of a stripper for cutting down the tape 31 (Figs. 1, 10), mounted on the base 26 (Fig. 1) under the backup roll 8 (Fig. 1) and consists of an arm 32 (Fig. 10), on which the strippers 33 (Fig. 10) are mounted. The number and position of them corresponds to the working grooves (not shown in the drawing) of the support roller 8 (figure 1). The working surface of the puller 33 (figure 10) removes the stuck waste cutting down the tape. The cage pulling 5 (Fig. 1, 5, 6) consists of a welded base 34 (Fig. 6), two rollers 35 (Fig. 5), a drive shaft 36 (Fig. 5) mounted on bearings 37 (Fig. 6) . The upper roller 35 (figure 5) is made with the possibility of its regulation by a tension screw 38 (figure 6) and fixation with a lock nut 39 (figure 6) on the basis of 34 (figure 6). On the basis of 34 (Fig.6) in front of the rollers 35 (Fig.5) is fixed with bolts 40 (Fig.12) wiping device 41 (Fig.12). The drive shaft 36 (Fig. 5) of the stand 5 (Figs. 1, 5, 6) receives rotation from the backup roll 8 (Fig. 1) through a belt drive 14 (Fig. 1), gear ratio i = 2.5. The carriage 3 (Fig. 1, 7-9), with a guide 42 (Fig. 8), made with the possibility of adjusting the width of the tape, is fixed by brackets 43 ((Fig. 9) to the base 1 (Fig. 1). Screw 44 ( Fig.7) carriage 3 (Fig.1, 7-9) is arranged to move on the plate 45 (Fig.7) of the spindle heads 46 (Fig.9), which are installed across the width supplied to the backup roll 8 (Fig.1) strip 47 (Fig. 8) and with the possibility of adjusting the position of the spindle heads 46 (Fig. 9) relative to the cutting punches 7 (Fig. 1). Fixing of the spindle heads 46 (Fig. 9) is carried out

locknut 48 (Fig.7). The cleaning device 41 (Fig. 12) is made in the form of two plates 49 (Fig. 12), with felts installed on the plates 49 (Fig. 12), mounted on four brackets 50 (Fig. 12) to the pulling stand 5 (Fig. 1) , 5, 6). The wiping device 41 (FIG. 12) is configured to adjust its position on the stand of the towing 5 (FIGS. 1, 5, 6) and fix it with bolts 40 (FIG. 12).

A device for perforating thin long workpieces works as follows.

The guides 42 of the carriage 3 are installed on the width of the tape with a screw 45 and set relative to the work rolls 7, 8. The tension rollers 35 of the pulling stand 5 and the wiper 41 are apart, the tape puller is raised. By adjusting the guides 42 of the carriage 3 device, the tape width is set with the screw 44 and its position is fixed with the lock nut 48. Depending on the thickness of the tape, the work rolls 7, 8 are adjusted with the screw 28 and fixed with the nut 29, while the tape is pressed with the tool roll 7 to the backup roll 8. The adjustment of the stand by the pulling 5 is carried out with a screw 38 and the positions of the lock nut 39 are fixed. The adjustment of the position of the wiper 41 is carried out manually, fixing the position by tightening with the bolt 40. The tape from the feed roll (on tezhe not shown) is supplied through guide roller 2 in a carriage 3 in which the guides 42 are adjusted to a predetermined tape width. Next, the tape enters the work rolls 7 and 8, cutting slotted grooves according to a given perforation card, and then into the cage pulling 5 and into the device winding (not shown). The upper tool roll 7 presses the tape against the lower support roll 8 and, in addition to the functions of cutting the tape, “pulls” it, feeding it to the pulling stand 5, which “smooths out” the burrs and irregularities resulting from the grooving of the grooves, also serves to stretch from sagging steel tape coming out from the work rolls 7 and 8. The device of the stand of the pulling 5 and the carriage 3 also create an irreducible bending, “clamping” of the steel strip along the bottom

backup roll 8 for the process of cutting. At the exit to the support roller and as the tape exits, they direct it to the wiping device 41 and then to the pulling stand. The rotation on the rolls 7.8 is transmitted through the gears 9 and 10 (gear ratio i = 1), the coupling 11, the gearbox 12, from the electric motor 13 by means of a belt drive 14.
