Description

I

The invention relates to pressure treatment of materials, in particular, equipment for the manufacture of slotted screens.

A device for the manufacture of slotted sieves is known, which contains a drive mandrel and a wire stacker G11. However, technological possibilities are possible. The features of the known device are limited.

Closest to the proposed technical essence is a device for the manufacture of slotted sieves containing a drive cone mandrel mounted on a frame, a wire stacker and a housing with correct rollers and tensioner 21 placed on the stacker.

A disadvantage of the known technical solution in Tom is that the technological possibilities are limited.

The purpose of the invention is to expand the technological capabilities of the device.

This goal is achieved by the fact that in the device for the manufacture of slotted screens, there are mounted a tapered mandrel, a wire stacker and a housing with correct rollers and tensioning device placed on the stacker, it has a mechanism for displacing one of the rows of correct rollers in the direction perpendicular axis of laying the wire on the mandrel.

In addition, the displacement mechanism has a screw rod mounted on the housing and attached to the bottom row of rollers.

1 shows a device, a view in plan; Fig. 2 is a view of A; Fig. 15 in Fig. 3 is a view of B in Fig. 2;

The device consists of a conical mandrel 1 mounted on bearing supports 2 and connected with a special driver 3 to a drive consisting of electric motor A, gearbox 5 and gearbox 6. Before the mandrel there is a wire stacker 7 having a screw drive and carrying the straightening unit 8 and nat General adaptation 9. The dressing unit consists of the body 10 and the correct rollers of the three top 11 and two bottom 12.

The upper rollers 11 are able to move up and down against the stop with the lower rollers 12. Along the circumference of the upper and lower

rollers there are grooves 13, in which the wedge-shaped wire 14 is placed. The position of the lower roller 12 is fixed by nuts 15. An unwinding device 16 is installed behind the stacker.

The device works as follows.

The wire is ground out of the coil located on the unwinding device 16. The front end of the wire is passed through the tension device 9 and the straightening unit (RITITKKH), and then attached to the flange of the future sieve attached to

the small base of the conical mandrel. The wire is clamped in the tensioner 9, which brakes the wire, then placed in the grooves of the upper 11 and lower straightening rollers 12 and lower the upper rollers onto the lower ones, the wedge-shaped wire bends, and the grooves of the upper and lower rollers coincide and are not shifted. The device is started up and the wire is wound on the ogfukka 1. The tensioning device 9 and the straightening unit 8 brake the wire and it is tightly placed next to the previous screw of this wire on the mandrel 1. It is laid on the mandrel 1 with the working base. When stitching the wire to the side plane of the wedge, the lower rollers with nuts 15 move along arrow C relative to the upper ones, across the movement of the wire and the wire in the stream x-grooves 13 is fixed rigidly in the opposite direction to stall on mandrel 1. additionally are deformed to the side when the lower rollers 12 are displaced relative to the upper 11. The found value of the displacement of the lower rollers relative to, the upper rollers are fixed by nuts 15.

In connection with the use of the invention, it became possible to make slotted rotary sieve bodies not only from annealed, but also from riveted, very wear-resistant wire.

any sizes of section. Sieves made of riveted wire have a life of two max. Sometimes 10 times longer (depending on the properties of the material being dried) than of the annealed wire, since fewer ones wear out over time. In addition, the performance is doubled.

device manufacturing sieves and reduced by about 20% consumption of stainless wire. Such a constructive solution of the device significantly expands the technological capabilities, which makes it possible to manufacture slotted screens not only from the annealed wire, but also from the cold-worked wire.
