Description

(54) DEVICE FOR ROLLING OF ROLLS

peernost

The invention relates to metalworking and can be used in the machining of external and internal surfaces of annular grooves. .

A device for knurling cylindrical surfaces, comprising a housing and a holder with a rotating deforming roller, is installed with the possibility of turning PI.

However, such a device cannot be used to treat several surfaces.

The chain of the invention is to provide simultaneous treatment of the outer and inner surfaces of annular channels.

It is achieved by the fact that the holder is additionally equipped with a second roller and flat springs that hold the holder in the initial position.

FIG. 1 shows the described device in the initial position; in fig

2- the same in the working position; in fig

3 and 4 - sections A-A and BB in FIG. 2

The housing 1 of the device is fixed in the tool holder 2 of the machine. In holder 3,

connected by a hinge 4 to the housing 1, two cylindrical deforming rollers 6 and 7 are mounted on bearings 5. Preliminary tension of bearings 5 is carried out with the aid of nuts 8. The holder 3 is held in the initial position by flat springs 9 and 10 fixed to the housing 1.

The device is guided to the machined part 11 so that the deforming rollers 6 and 7 fall into the ring-shaped groove of the part 11 (Fig. 1). The rotational motion is last reported, and to the device body 1, the feed movement S When the device moves with the feeding movement, the deforming roller 7 interacts with the outer machined cylindrical surface D, turns the shaft 10 3 relative to the body 1 until the deforming roller 6 begins to interact with the inner (The cylindrical surface being actuated d. The flat spring 9 is bent. The device occupies the working position, rolling the outer B 36 and the inner d cylindrical surfaces the ring-shaped groove of part 11. After rolling these surfaces, the feed movement is reversed, the holder returns to its original position under the action of flat springs 9 and 10, and the device is retracted from the workpiece 11. The device for rolling the surfaces of annular grooves, comprising a housing Phie. 2 0 and a deforming roller located in a holder mounted for rotation, characterized in that, with whole single machining on the outer and inner surfaces of the annular grooves, the holder is additionally equipped with a second roller and flat springs, designed to hold the { a) mounts in the starting position.
