Description

 The invention relates to the field of machine tools, and in particular to equipment for the manufacture of reinforced barbed tape.

A device is known A machine for the manufacture of spirals, a description of the invention to the patent of the Russian Federation 2077404, IPC ⁷ B21F 25/00, publ. 04/20/97, 11, ed. Mesyats A.A., Malevich P.Ya. (analogue). The machine for the manufacture of spirals includes a bed 1 with drive stands 2 for profiling barbed tape and squeeze stands 3 for rolling barbed tape 4 of spring wire 5 and signal wire 6. The machine has unwinding devices with coils (bobbins) for barbed tape 7, wire 8 and winding device with a drum 9.

A spiral storage container 11 is attached to the lower end of the drum. The machine is driven by an electric motor with a reduction gear, V-belt (chain) transmission and a remote control.

 Disadvantages: this device is bulky, difficult to manufacture, and it is also impossible to adjust the feed rate of the reinforced barbed wire.

A device for reinforced barbed tape, a description of the invention to the patent of the Russian Federation 2183526, IPC ⁷ B21F 25/00, publ. 06/20/2002, ed. Khimichev V.A. Gubaidulin V.Kh., Nikiforov P.V. (prototype).

 A device for reinforced barbed tape containing a bay holder, a drum for winding reinforced barbed tape, a pair of rollers also contains a frame that rotates on two hollow axes, through the first of which a reinforcing core is passed, and through the second - a barbed tape and reinforcing core, frame and rollers connected to the drive, the rollers are compressed, and in one of the rollers a groove is made for core reinforcement, the drum for winding reinforced barbed tape is equipped with a mechanical drive and a spiral coil stacker, and the distance between adjustable frame and drum adjustable.

 Disadvantages: since the barbed tape is wound on the core, a large percentage of the wire is open, not rolled, and this does not provide sufficient rigidity and resistance to cutting the barbed wire.

 Effect: increasing stiffness and resistance to cutting reinforced barbed tape by crimping wire with barbed tape, increasing productivity by combining operations, controlling the speed of movement of barbed tape over a wide range.

 The task is carried out by the device due to the fact that in the known device containing the coil of the wire, a spool of barbed tape and a drum for winding reinforced barbed tape, where between them are installed rollers with a groove for the wire, where the rollers form the upper and lower and the crimp rollers upper and lower mounted vertically one above the other, and between them there is a rotary guide in the form of an inverted tape in the transverse direction from the horizontal plane to the vertical, respectively, from the rollers squeezed to the crimp rollers, toward the latter, and having a longitudinal groove, the rollers forming the upper and lower interconnected by means of radial protrusions and grooves made on the outer diameter, and grooves are made at the ends of the crimp rollers on the upper and lower diameters in place the clamping of the crimp rollers is installed perpendicular to the last, the roller straightening the spikes of the reinforced barbed tape, with a radius protrusion along the outer diameter. The output of the reinforced barbed tape from the forming rollers, where a longitudinal groove was formed already in the barbed tape and the wire entered into it, and then, moving along the rotary guide, the reinforced barbed tape is turned in the transverse direction and occupies a vertical position together with the crimped rollers.

 In the crimp rollers, the final rolling of the wire into a barbed tape takes place and at the same time the studs are straightened by a roller straightening the spikes of the reinforced barbed tape. Such a design and the interconnection of all its elements will reduce the time for manufacturing reinforced barbed tape by combining operations - the final compression of the wire of barbed tape and the formation of its spikes, and this reduces the time for manufacturing reinforced barbed tape, which increases productivity, as well as this design allows you to adjust the speed from the initial to three meters per second. Compression of the wire from all sides increases its rigidity and resistance to cutting (this reinforced barbed tape cannot be bitten with nippers). In the prototype, barbed tape is wound on the wire and the bare spots of the wire are a weak point for cutting it, and this reduces its rigidity and resistance to cutting.

 A device for manufacturing a reinforced barbed tape contains a coil holder 1 of wire 2, a coil 3 of barbed tape 4 and a drum 5 for winding a reinforced barbed tape 6, where the rollers forming the upper 7 and lower 8, crimp upper 9 and lower 10, which are located vertically one on top of the other, and between them, in turn, a rotary guide 11 is installed in the form of an inverted tape in the transverse direction from a horizontal to a vertical plane, respectively, from forming rollers to crimp ones, and it is turned in the side of the crimping rollers and has a longitudinal groove 12. The rollers forming the upper and lower are interconnected by means of a radius protrusion 13 and a groove 14, respectively, made on the outer diameter of the forming rollers. At the ends of the crimping rollers of the upper and lower diameters, recesses 15, 16 are made, and at the junction of the crimping rollers, a roller 17 is installed perpendicular to it, spreading the spikes 18 of the reinforced barbed tape 6, while a radius protrusion 19 is made in the roller spreading the spikes along the outer diameter for the final rolling of the wire into barbed tape. The device comprises an electric motor 20 connected to a chain 21 and an asterisk 22, rotating the drive gear 23, gears 24, 25 of the crimping rollers of the upper 9 and lower 10. Gear 24 is interconnected with the intermediate gears 26 and gears 27, 28, the rollers forming the upper 7 and lower 8 The device comprises pressure rollers 29 and a pressure plate 30, between which a barbed tape advances before entering the forming rollers. On the base 31, the driving gear 23, the gears 27, 28 of the forming rollers, the intermediate gears 26 and the gears 24, 25 of the crimping rollers, the pressing plate 30 and the pressing rollers 29 are attached. The forming rollers upper 7 and lower 8 have grooves 32, 33 for the wire. In the barbed tape 4, a longitudinal groove 34 is made.

 An example of the operation of the device.

Steel barbed tape of any steel is supplied from a freely rotating coil 3, and steel wire 2 from a freely rotating coil holder 1. Barbed tape 4 passes between the pressure plate 30 and pressure rollers 29, heading to the rollers forming the upper 7 and lower 8, where in the barbed A longitudinal groove 34 is formed in the tape 4 by means of a radial protrusion 13 and a radial groove 14 in the forming rollers, while simultaneously and parallel to it, a wire 2 moves, which is located between the grooves 32, 33 in the upper 7 and lower 8 forming rollers. When the forming rollers exit the rollers, wire 2 enters the longitudinal groove 34 formed in the barbed tape. Next, the barbed tape 4, already reinforced with wire 2, enters the rotary guide 11, which has a longitudinal groove 12 for the protrusion formed by the longitudinal groove 34 in the barbed tape 4 under wire 2, as it is turned in the transverse direction from the horizontal to the vertical, i.e. from forming rollers to crimping rollers towards the latter. The forming and crimping rollers, the upper and lower, are mounted vertically one above the other, where the rotary guide 11 is installed between them. Turning 90 ^° , the reinforced barbed tape enters the crimping rollers, where the tape is finally crimped around the wire and the studs 18 are formed, which are straightened by the roller 17, spreading the spikes 18 and having an outer diameter of a radius protrusion 19, which finally rolls the wire into a barbed tape. It is installed perpendicular to the crimp roller, at the junction of the upper and lower crimp rollers. Next, the finished reinforced barbed tape 6 is wound on a drum 5.

 The device operates from an electric motor 20 and through a chain 21, an asterisk 22, a pinion gear 23, gears 24, 25 transmits movement to the crimping rollers upper 9 and lower 10. Intermediate gears 26 (three of them) transmit rotation to gears 27, 28 and drive the forming rollers where there is a pressure plate 30 and pressure rollers 29 behind them.

 Thus, the wire 2 and the barbed tape 4 from the bay holder 1 and the reel 3 begin their advancement. On the base 31, the forming and crimping rollers are attached, the pressing plate and rollers.

 Technical and economic indicators.

 The use of the device increases productivity by 75% and increases the rigidity and resistance to cutting by 40% compared with the prototype.
