(54) MILLING AND WEDGE PRO1: ATKI

family paapeaj in FIG. 2 - section A-L a-fig, 1 | in fig. ; 3 - craHi, across the cut, in dze in dice in the direct course; ka ET. 4 is the same at the reverse course.

The power drive of the mill contains a reverse. § but a rotating gear gear 1 and 2, rigidly connected to the upper plate 3 which is installed in the forward guides of the bed 4, In the frame 4 there are side windows 5, bounded by vertical ones; stiffener ribs 6 in which the electric heater 7 is installed; .

On both Piits 3 and 8, a wedge tool is installed, the states gaj of parts 12, 13. 14, while the parts 13,14 are installed 20 are on loan from the opposite directions of the relative movement of the movable plate, Alites also have dies 15, 16 s. and the movement of the rod 17 of the pneumatic ftf & nwA-i: - 18 from one part 13 of the Kliovo 25 about the tool to the other part 14. - A plate 19, which interacts with the plate, is rigidly attached to the plate 15 on the bottom plate. 16 on the top plate, which consists of two parts, between which the fastener springs 20 are fixed 30.

The blank 21 is placed between the parts of the maple tool 12 and 13.

The upper plate 3 is moved forward; in this part of the 12, 13 wedge tool 35, the deformation of the workpiece 21 is deformed. At the end of the forward run, the slide 21 is installed between ;. with the sleeves 15 Е 16, the Stem 17 of the pneumo-cylinder 18 15 is moved to the part 14 of the tool. At the floor: - the sense of g 40 tep 19 interacts with the plate 16, moving it and the workpiece 21 to chag, - 14 tools. Execution of the die 3.v. the composite of two parts and the placement of the disc springs 2O between them reduce the 4S porous force between: in cloaks and facilitate their movement. After moving the plates 15, 16, the upper plate 3 moves back, rolling the workpiece by 21 parts 14 of a wedge tool. At50

This plate 15 is returned to its original position by the pneumatic cylinder 18, and the plate 16 by springs,

The mill may contain a wedge tool of three, four or more parts and 55 several gauge shields between them. In this case, the workpiece is rolled in more than one working cycle (direct plus reverse). Electric heaters heat up the vertical fins 6 gestures- 60

the bones to such a temperature that their left compensated for the reduction in the meter of rolled billet due to the heating of the wedge tool.

The heater is turned on and off automatically, depending on the stiffening tag of the vertical ribs and in the temperature of the tool. In the case of a closed mill, the pins 11 of the nests in the nests in the top plate 3 are stirred forward, the movement from the plate 3 turn the workpiece 21 is transferred to the bottom plate 8. The bottom plate 8, moving forward, slides along the wedge plate 9, thereby increasing the distance H0e Parts 12 and 13 of the instrument. In the working positions of the wedge plate, the 9 sc is used to adjust the distance | between yu shkhity 3 and 8, i.e. for adjustment. the maximum diameter of the rolled billet

The use of the reverse drive leads to an increase in the mill's productivity not less than in the two & times. In the proposed camp tool plates & t you ". They are several times smaller than the total length of the tool, which significantly reduces the size of the mill.
