The invention relates to the machining of materials, in particular, to devices for processing wires and making wire filters therefrom.

A device for the manufacture of wire filters is known, which is a special winding-welding machine on which the fixation of the wire helix is made by welding. In the manufacture of filters, special trapezoidal section wire 1 is used.

However, the development and manufacture of these machines are costly.

It is also known a device for the manufacture of wire filters, comprising a drive faceplate with a clamping device for fixing the filter cage, a tailstock and a means for tensioning the wire, consisting of two profiled rollers 2.

In the known device, as the frame rotates, the wire is wound on it, forming a filter sheath in the form of a spiral. The fastening of the spiral turns on the frame is ensured by the forces of friction, which does not always ensure their reliable fixation on the frame, as a result of which, when transporting and installing the filters, the turns shift to form unacceptable gaps. A disadvantage of the known device is the fact that it uses expensive pipe-cutting machines with an elongated frame.

The purpose of the invention is to improve the quality of the filter.

This goal is achieved by the fact that the device for the manufacture of wire filters, containing a drive plate with a clamping device for fixing the filter frame, a tailstock and a means for tensioning the wire, consisting of two profiled rollers, has a cylindrical yoke, thread-cutting means, consisting of mounted on the front end of the holder of tool holders with clamps and adjusting screws placed in the tool holders, cutters, and removable sleeve with screw thread placed inside the holder, step to The wire is equal to the wire pitch on the filter frame, the profiled tensioning rollers are fixed on the rear end of the yoke, while the lower roller has a groove on the working surface corresponding to

wire profile, and the upper roller - transverse knurling.

FIG. 1 shows the general scheme of the proposed device for the manufacture of wire filters; in fig. 2 shows section A-A in FIG. one; in fig. 3 - holder, general view; in fig. 4 — node I in FIG. 3 (profile of tensioning rollers).

The device contains a holder 1, a drive plate 2, indicating rotation of a perforated ribbed frame 3 made, for example, of polyethylene, and a coil 4 with plastic wire 5. The holder includes a housing 6, a thread-cutting part made of tool holders 7

5 with removable cutters 8, clamps 9 and adjusting screws 10. Inside the cage is a calibrated clutch 11 for feeding the cage. Removable swivel castors are installed at the end of the cage.

Q 12, laying the wire into the locking grooves, cut by incisors on the ribs of the frame 3, and giving the wire the desired profile. The tension of the wire is created with the help of clamping, spring-loaded bolts 13. The lower rollers have grooves 14 corresponding to the specified profile, and the upper rollers have transverse knurling 15. The yoke is provided with stop handles 16.

The device works as follows, the frame of the filter 3, having at the ends

0 thread for connecting the filter links, is installed in the drive faceplate 2, the clip 1 is screwed onto the end. Wire 5 is passed through the crimping rollers 12 and fixed to the frame 3, after which the rotation drive of the faceplate 2 is activated.

5 rotation of the frame 3 cutters 8 are cut into the grooves of its edges. The wire, passed through the crimping rollers 12, is deformed and stacked spirally in the grooves on the ribs of the frame. Thus, the device

 allows you to simultaneously cut the locking grooves, to impart a given profile to the wire and to wind the wire helix with a given size of filter slits. At the end of the winding, the end of the wire is sealed in an ot5 version on the frame 3.

The use of the proposed device makes it possible to improve the quality of the wire filter by making the filter gaps more accurate and more securely fastening the wire helix to the frame.
