The invention relates to equipment for the production of wire by slitting the tape material.

Famous line for the production of wire containing uncoiler, installation for butt welding, drive belt, the correct device, the multiple disc cutters for slitting the tape, the multiple node processing the edges of the wire, multi-row block fiber and winding device. The processing unit of the edges of the wire is used to remove burrs from the edges of the rectangular wires formed during slitting of the tape. It contains a rotating abrasive tool to the surface to which the wire is fed alternately to each edge by a complex system of roller guides (patent RU NO. 2102168, 21 1/00, 1995).

The closest is the line for the production of wire containing uncoiler, installation for butt welding, drive belt, multi disc cutters for slitting the tape, the multiple node processing the edges of the wire, multi-lane drive-wire, multi-row block fiber and winding device. The processing unit of the edges of the wire consists of two elements that are installed with the possibility of counter-reciprocating movement in the longitudinal direction from the actuator and having holes for the wires, the diameter catarinense the diagonal size of the cross-section of the wire. The fiber block provides the receive wire of circular cross section. Winding device moves the wire during its processing (patent RU №2235617, 21 43/04, 2004).

Significant tension on the wire needed to pull when cutting, processing of edges and drawing created by the winding device, may lead to its breakage and stop lines. Low reliability is especially dangerous when a large number of simultaneously processed wires, for example 100-150 wires that usually takes place in the manufacture of wire "fan" way, i.e. by slitting the roll of material.

The technical result of the invention is to reduce the breakage of the wire due to the reduction efforts of her tension.

This is achieved by the fact that the line for the production of wire containing uncoiler, installation for butt welding, drive belt, multi disc cutters for slitting, multi site processing of the edges of the wire, multi-lane drive-wire, multi-row block fiber and filament winding device according to the invention is equipped with two multi devices twisting the wire about its axis, one of which is located before site processing of the edges of the wire, and the other providing the twisting in the opposite direction is, posted by after processing node edges of the wire, and the processing node ribs made of at least two stationary sets of coaxially mounted abrasive disks with mechanical work surfaces, spaced from each other with a gap smaller than the diagonal of the cross-section of the wire, and the same set that is installed on the other side of the wire between stationary sets with the possibility of lateral movement for adjusting the position relative to the stationary sets, with each set of abrasive disks are equipped with a drive of rotation and is mounted coaxially with him driving the traction drum having the opportunity to interact with the wire, passed through a gap between abrasive discs.

The invention is illustrated in the drawing, in which figure 1 schematically shows a production line wire; figure 2 - node processing ribs.

In line are consistently located uncoiler 1 for placing the roll of tape 2 material 3, a device 4 for welding the ends of the tape material butt, 5 tape drive, multi disk scissors 6 for cutting material 3 wire 7 is approximately square cross section, the first device 8 of the winding wire, the node processing the edges of the wire, consisting of three stationary sets and rativnyh disks 9 and two sets of 10, mounted on the carriage 11, movable in the transverse direction (shown by arrow), the second device 12 of the winding wire, multi drive 13 wire, multi unit plate 14 and the winding device 15.

Each set of 9 and 10 discs consists of abrasive disks 16 with mechanical work surfaces and traction drum 17 mounted coaxially between the working surfaces of the disks 16 there is a gap a, which is a cylindrical surface traction drum 17. Drive abrasive disk (not shown) provides rotation with a speed that provides the specified processing mode wire. Traction drum 17 is driven by a separate actuator providing linear speed of 2-5% greater than that of the wire feed speed that is necessary for the intermediate traction devices operating with slip. You can also rotate the traction drum 17 from the drive abrasive disks through kinematic transmission.

The line work is carried out as follows. On the decoiler 1 set roll 2 of tape material 4, the front edge of which is welded butt joint with the rear edge of the preceding roll by means of the welding device 4. During installation, roll and weld line is not terminated because the drive 5 has an adequate supply of l is tochnogo material. Next, the material passes between the circular knives multi shears 6 and is cut into narrow strips wire 7 is approximately square cross section. Multi twisting device 8 provides the twisting each wire around its axis at a small angle, for example, clockwise. Multi twisting device 12 provides twisting each wire around its axis in the opposite direction, resulting in her return to the non swirling condition. And only the section between the device 8 and 12, where the abrasive disks 16 of the processing unit of the ribs, the wire passes, continuously turning, resulting in uniform abrasive processing of all edges of the wire and removing concentrated in these areas of defects. Depth of processing is governed by the size of the gap and between adjacent abrasive discs 16. Traction drums 17 are sliding. The tension on the wire, created by them, depends on the total number of traction drums and angle setting for each drum wire, which can be adjusted by changing the position of the carriage 11. Additional traction is created abrasive disks 16, which rotate in the direction of movement of the wire through the fair grinding". As a result, the first is, the node itself is the processing of edges does not create resistance to movement of the wire and, secondly, it provides the tension required for shears 6, without the participation of the winding device. This reduces the load on the wire when being drawn through the multiple fiber block 14, where the wire gets a round cross-section and where the probability of breakage of the most high.

Line for production of wire containing uncoiler, installation for butt welding, drive belt, multi disc cutters for slitting, multi site processing of the edges of the wire, multi-lane drive-wire, multi-row block fiber and winding device, characterized in that it is equipped with two multi devices twisting the wire about its axis, one of which is located before site processing of the edges of the wire, and the other providing the twisting in the opposite direction, is placed after the node processing the edges of the wire, and the processing node ribs made of at least two stationary sets in the form of coaxially mounted abrasive discs mechanical work surfaces, spaced from each other with a gap smaller than the diagonal of the cross-section of the wire, and the same set that is installed on the other side of the wire is key between stationary sets with the possibility of lateral movement for adjusting the position relative to the stationary sets, each set of abrasive disks are equipped with a drive of rotation and is mounted coaxially with him driving the traction drum having the opportunity to interact with the wire, passed through a gap between the abrasive discs.
