Description

one

The invention relates to equipment for the manufacture of mesh sheets with roll-off intervals between the grids.

Automatic machines for producing grid cloths with rotating and non-rotating crossbars are known, comprising a winding mechanism with a winding mandrel, cutting and rolling knives and clamping jaws, a feed mechanism for the cross bars in the drive.

The purpose of the invention is to improve the quality of rolling the last turns of the nets due to the unloading of the rolling from the force of the wire break.

For this, the rolling knife is provided with an additional blade placed across the working knife of the knife and protruding Hc1D.

FIG. 1 shows the device; in fig. 2 - the scheme of rolling the winding wire in the last notch on the traverse of the net and fixing the wire breakage.

The device comprises a winding mechanism with a winding arbor 1 / cutting 2f roller 3 knives and clamping jaws 4, a traverse feed mechanism 5 and a drive of the cutting blade and shaft of all knives. The latter consists of

an eccentric 6, a lever system 7, a lever 8, a lever 9 with an adjustable stop 10. The stock of the coiling wire 11 is wound on a coil 12 fastening on the winding mechanism. The traverse wire 13 of the net fabric is passed through the spindle into the grooves of the mandrel 1 and the locking mechanism 5 of the feed in the lock. Rolling knife 3 is equipped with

0 additional blade 14, located across the working edge of the knife and the protrusion {we feel above it.

The winding process begins when the coiling wire 11 is fed into an ea5 tube from the cutting knife 2 on the XZ traverse. The winding pitch is formed by moving the carriage of the feed mechanism 5. Coiling wire 11, coiling off coil 12,

0 is laid in the notches on the yoke 13, which slides along the grooves of the mandrel 1, and is rolled by the knife 3 in the usual manner on the section of the regular mesh from the first notch on the traverse

5 on the penultimate. After rolling the wire 11 in the penultimate notch on the traverse 13 of the next mesh, the cutting knife 2, which made the last notch on the traverse 13, is retracted from

Claims (1)

0 of the mandrel 1 so that it does not touch the traverse 13 during the passage of the neuwebit interval. Simultaneously with the retraction of the cutting knife 2, located on the lever 8, the eccentric 6, kinematically connected with the lever system 7, providing retraction and supply of the cutting knife, rotates the lever 9, which in turn, with the adjustable stop 10 rotates the rolling knife 3 and thus brings the area of the rolling knife 3, designed for rolling the coiling WIRE 11 in the last notch on the traverse 13 of the next grid. The above knife 3 produces the last rolling, at the end of which, in the process of running the knife 3 along the traverse 13, the winding wire 11 comes into contact with an additional blade 14 placed across the working edge of the knife 3 and protruding above it. The wire is bent over this blade and cut off (see Fig. 2). After breaking the wire 11, the lever carrying the roller blade 3 and the guide-clamping jaws 4 is retracted from the mandrel 1 so that the roller blade 3 and the free end of the wire 11 clamped in the edge position in the jaws 4 do not touch the yoke 13 during the passage of the non-spiral grid spacing. After going through the wrap-free interval, the lever 8 carrying the cutting knife 2 is guided to the mandrel .1 for winding the next web mesh, while the eccentric 6 connected to the lever system 7 providing the retraction and supply of the knife 2 rotates the lever 9 carrying the adjustable stop 10 and thus the section of the rolling knife 3 / intended for rolling the coiling wire 11 in the usual way on the section of the next grid from the first to the last but one notch on the crossheads. Apparatus for making radio grids grids, comprising a winding mechanism with a winding mandrel, cutting and rolling knives and clamping jaws, a traverse feeding mechanism and a drive, characterized in that, in order to improve the quality of rolling the last turns of the grid, the rolling knife is provided with an additional blade, placed across the working edge of the knife and protruding above it.
