Abstract

A device for manufacturing profile rings from sheet blanks containing a bending roller with a mechanism for moving it, characterized in that it is equipped with volumetric cams mounted with the possibility of rotation relative to the axis of symmetry and a movable calibrating profile ring, the cams being made expandable in the radial direction and the diametrical surfaces of the cams and the clamping ring are made with a reverse cone of 1 - 1.5 ° for reliable fixing of the workpiece.

Description

DEVICE FOR MANUFACTURE OF PAST RINGS

The device relates to the processing of metals by pressure, in particular for devices for the manufacture of profile rings from sheet blanks.

Known stamp for producing similar parts by molding, containing on the top plate a matrix with movable spring-loaded bending elements (AS USSR f 959869, V21D7 / 02, 1982).

The disadvantage of this stamp is the impossibility of manufacturing rings of predetermined profiles without waste technology. In addition, to obtain a blank for molding, it is necessary to produce a die cut die, as well as to use unique equipment (curved presses) to obtain large diameter rings.

The closest analogue is a device for flanging pipe edges, (USSR AS No. I4007I8, class V21D19 / 00 - prototype) containing a housing that has been washed on the eyes of the axle forks and running rollers mounted on them.

The disadvantage of this device is the inability to fix non-rigid blanks such as shells to obtain G and P shaped rings.

The proposed device is characterized in that it is equipped with volumetric cams mounted with the possibility of rotation relative to the axis of symmetry and a clamping, calibrating profile ring, moreover, the workpiece is installed between the diametrical surfaces of the volumetric cams and the clamping ring and secured by a2 at A / B1) Object - device Authors: Kutyn Victor Nikolaevich

bench press in radial marking. The diametrical surfaces of the volumetric cams and the clamping ring are made with a reverse cone I 1.5 °,

In Fig, I shows a device for the manufacture of profile rings in the context.

In Fig, 2 shows the proposed device, a left view.

On Fig, 3 shows the initial position of the workpiece and a tool for rolling profile rings.

The device is mounted on a turning chuck I, contains volumetric cams 3 mounted with fixing bolts 6 on the combs 2, a clamping calibrating profile ring 4, and a bending roller 7, Volumetric cams 3 and a clamping calibrating profile ring 4 are made with the reverse 1+ 1,5 ° (Fig. 3), which ensures reliable fastening of the workpiece 5 and does not allow its axial movement in the rolling process 1.

Billet 5 (FIG. 3) (initial position) is a shell obtained after rolling a strip of material (aluminum, brass, copper, duralumin, annealed steel), welded or not welded to form, depending on the purpose, the finished part.

The device operates as follows: the workpiece 5 (FIG. I), calculated by diameter and width, is installed between the diametrical surface of the volumetric cams 3 and the clamping, calibrating, profile ring 4 and the expansion cam of the volumetric cams 3 is fixed in the radial direction. A roller 7 (FIG. 3), the holder of which is fixed in the tool holder 8 (FIG. 3) of a turning or turning-rotary machine, comes into contact with a rotating workpiece 5, exerting pressure on the surface of the workpiece using the transverse and longitudinal movement of the machine support.

V / I / S.

The resulting plastic bend due to rotation

the workpiece expands along a helix. Sequential deformation of the material into a clamping, calibrating, g-shaped ring shields the workpiece 5 with the necessary shape (see | ig. 3),

For a welded along the forming shell in the profile ring, a groove under the weld is selected. Setting up the device for the manufacture of drutoooo profile parts and dimensions consists in replacing volumetric cams and profile ring

The production technology is non-waste, not requiring the manufacture of bulky stamped tooling and the use of sophisticated equipment.
