The invention relates to the processing of metals by pressure and can be used to obtain the tapes from rolled round, square, rectangular sections made of different metal, including heat-resistant and stainless steels.

Known construction mill rolls, consisting of two cylindrical rolls, between which is passed a car (1).

A well-known tool for cross-wedge rolling, containing the base and set it working sloping wedges primary and secondary deforming faces, steps are formed by the pads parallel to the base and associated with deforming faces (2).

The tool is used for rolling cylindrical parts, where the wedge is made parallel to the base. This method cannot be deformed continuously moving car.

There are design of cross-wedge rolling mill, where working tool consists of rolls with wedge calibration. Work rolls have a diameter of up to 980 mm, Making them very difficult, most metal (3).

Such rollers cannot be processed continuously moving car, for example tape.

Known constructions of rotary forging machines (the prototype of the invention) with a fixed spindle, rotating around his cage with cage and cylindrical rollers acting on the sliders and jaunty (4). The return of floaters after compression is provided by the springs.

The disadvantage of this design is the shape and complicates the manufacture. Additionally, this design makes use of shims mounted between the slide and the punch and compensating the wear of the punch, which reduces its service life.

The technical result consists in the improvement of operational properties dvuhvekovoi rotary forging the head, excluding warp processed hire in obtaining the maximum broadening and high quality machined steel.

The technical result is achieved by the fact that in the machine for the manufacture of the ribbon of steel that contains a frame, the node changes, the node manual feed, friction clutch, dvuhvalkovyy rotary forging the head with a rotating outer ring and the strikers, the working surface of which consists of lead and calibrating stations, and a means of returning strikers in the starting position, the tool will return Boykov made in the form of spring-loaded inserts, angled 90aboutthe strikers with the opportunity to interact with them, while the lead-in area of the heads is made with the guide cavity in the form of rent and is situated at an angle 8...15aboutto its base and contains a wedge with oblique forming its sides, and calibrating usetoday, and their height corresponds to the tolerance rental in thickness, and degree connected with each other inclined to the plane of the sections.

In Fig.1 shows the proposed machine; Fig.2 is a view along arrow a in Fig. 1; Fig.3 - die in plan; Fig.4 - section b-B in Fig.3; Fig.5 - section b-b of Fig.4.

Machine for the manufacture of strips of Bicycle comprises a frame 1 on which are mounted all of the nodes: the node edit 2 roller type edit in 2 perpendicular planes, the node manual feed 3, consisting of 2 rollers with manual drive one of them; a rotary forging head 4, which is in the shape of the tape from the car; the mechanism of a tension of the tape 5, consisting of two rollers driven by a DC motor through a reduction gear (Fig. not shown), which simultaneously drive unit winding 6 with a friction clutch (Fig. not shown), consisting of a drum on which is wound the tape.

Rotary forging head 4 consists of a rotating outer ring 7, in which set-up roller 8, which interacts with a fixed spindle 9 and the slider 10, through which the strip 11 impact on Boiky 12, the reverse of which is provided stawk the second cavity to hire 17, parallel to the base of brisk. Guide cavity to avoid misalignment of the car when applying for a wedge 18, which is formed by the cavities 19.

The wedge 18 is made at an angle equal to 8-15aboutto the bottom of the firing pin and is used to obtain the necessary broadening, depending on the angle of taper . With increasing angle of taper increases broadening. Thus the angle (15-70about) is selected depending on the required broadening and depending on the section of the car.

The angle of the side surface of the wedge = 45aboutserves to improve the quality of the surface and its reduction improves surface quality, but increases the effort of shaping.

Wedge surface 18 formed by the cavities 19, enters the calibrating section 20, parallel to the ground. This section calibrates extended rental in size.

Calibrating section 20 moves in the compensation section 21, parallel to the ground, consisting of degrees, perpendicular to the axis of the feed drop speed on tolerance tape thickness, and transitions degrees angled. Steps serve to improve the surface quality of the tape.

When you wear calibrating participants.D.

Machine for the manufacture of tapes from the rental operates as follows.

Car from the Bay manually through the dressing mechanism 2 is fed to the node in the manual feed 3 with manual drive one of the rollers, which car is sent to a rotary forging head 4, where he pornoamatuers in the tape. Then the tape moves to capture the tensioning mechanism 5, which is driven by a DC motor through a gearbox. The tape is supplied to the node winding 6, which is fixed. Node winding 6 is connected with a drive through the friction clutch to slip when changing the speed of winding of the tape due to the increasing diameter of the winding.
