Description

I

The invention deals with the processing of: metal pressure, in particular, devices for processing a profile of parts such as disks, and can be used in mechanical engineering.

A device for machining parts by means of surface plastic deformation is known, in the case of which opposite each other are placed with the possibility of translational movement of rolling heads with balls placed in separators mounted on mandrels 1.

The main disadvantage of the known device is the inability to use it for three-sided rolling of a profile of parts (at two ends and forming simultaneously) of the type of discs.

The purpose of the invention is the expansion of technological capabilities.

The objective is achieved in that the device is provided with cylindrical rollers located in the separators.

And a profile roller mounted between the rolling heads on the mandrel, with the rolling heads being kinematically connected to each other.

FIG. 1 shows the proposed device, the cut; in fig. 2 - profile roller; in fig. 3 - section A-A in FIG.

The device comprises a housing 1, to the side surfaces of which a crepe T10 from the cheek 2, c. the lugs of which are mounted carrier rolling heads, located opposite each other, moving in the axial direction, consisting of separators 3, resting on

15 fixed mandrel i. On the neck of the separator, there is a bearing 5) on which a holder 6 of sleeve 7 is mounted with a bearing 8 and a washer S In the sockets of the separator 3 balls 10 are installed and

20 rollers 11. In the middle part of the mandrel C, fixed by screw 12, bearings I3 are installed with a profile roller, on the side face of which there are inclined grooves 15 "forming a wave-like profile, which contributes to intensification of the process of forming profile 11 Roller "provides an opportunity to periodically fill the recess of the profile with a certain amount of metal, which is then displaced in the direction along the radius of the workpiece from the center to the periphery. The slope of the roller profile contributes to a smooth flow of metal in smaller quantities, but at a larger angle of rotation of the profile roller I, which forms a closed loop with the balls 10 and rollers 11. A screw 17 having right and left threads cooperates with the threaded holes of the separators 3. The device operates as follows. The device is installed in place of the tool holder lathe. The workpiece 16 is clamped at the ends between the mandrels 18 and 19, mounted in the chuck and the tailstock of the machine, and set it to rotate. The formation of a three-sided profile begins when the balls 10 come into contact with the face surfaces of the part 16. Rotating screw 17 reduces the rolling heads, which contributes to the extrusion of the metal between the cylindrical rollers 11 towards the profile roller N. When a part of the required profile is received, the rolling of the rolling heads is stopped and their removal begins . The advantages of the proposed device, in comparison with the known one, are that it is possible to form a triangular profile immediately, which is 2-3 times more productive. The invention of the device for machining parts by the method of surface plastic deformation, in the case of which opposite to each other are arranged with the possibility of translational movement, the rolling heads with balls placed in separators are mounted on a mandrel, characterized in that, in order to expand technological capabilities, it is provided with cylindrical rollers located in the separators, and a profile roller mounted between the knurled heads on the mandrel, while the knurled heads are kinematically skiing connected to each other.
