Abstract

The invention relates to the processing of metals by pressure, namely to sheet metal stamping, and can be used to produce thickened sheet metal sheets. The purpose of the invention is the expansion of technological capabilities by increasing the pasf. epoB thickening. The device contains a base 1 with heating elements 2 mounted on it and pressure plate 5 installed on it and guide 6 plates with grooves, as well as a deforming roller (DR) 3. The device has clamp (П) 4 having the ability to move along the slots of plates 5 and 6. The surface P 4, in contact with the DRR, is delineated along a radius equal to the radius of the RS. This prevents the formation of metal float in front of the DRZ when processing the heated sheet stock DRR. 3 silt, 1 i (L ff X iJ 00 4 CO P & phi & 1

The invention relates to the processing of metals by pressure, namely sheet metal forming, and can be used to produce sheets with thickening.

The purpose of the invention is the expansion of technological capabilities by increasing the size of the bulges.

Fig. 1 shows a device for producing bulges on sheets in the initial position, front view; in fig. 2 - the same, in the process of obtaining thickening, section A-A in FIG. 1; FIG. 3 is a sectional view of FIG. 2.

The device comprises a base 1 with heaters 2 installed throughout the length, for example, heating elements, on which a sheet blank is installed, a deforming roller 3 made in the form of a stepped wheel and mounted with the possibility of longitudinal movement relative to the base 1, the device also has a pressure 4. the longitudinal movement through the pad, made in the pressure 5 and the guide 6 plates, and is in contact with the outer surface of the deforming roller, and the pressure surface 4, is in contact contact with the outer surface of the deformable ro peak. 3, is made with a radius equal to the radius of the deforming roller. Radial movement of the deforming roller is carried out, for example, by means of a hydraulic cylinder through the axis of rotation of the roller (not shown), and rotation is carried out by active friction forces between the deforming part of the roller and the sheet stock. a ring 7 spring-loaded, for example, by springs 8, each spring being mounted on a spoke 9, one end of which is fixedly connected to a deforming roller and the other has free movement along the groove in ring 7 in a circumferential and axial direction detecting x. The base 1 is movable and set in motion from the electric motor through a gearbox and a worm gear (not shown). The outer diameter of the ring 7 and the deforming roller 3 are the same and they are mounted coaxially with each other.

The device works as follows

2 is heated in the deformation zone i along the entire length of the workpiece to a predetermined temperature. A baffle clearance is established between the surface 5 of the base and the deforming roller, which is O, O3-0.055o, where S is the initial thickness of the sheet blank, which is fixed by means of the pressure plate 5 to the deforming roller 3, and is rolled by deforming roller the length of the edge of the sheet preparation, while the material from under the roller is squeezed out and gathered in the form of a thickening under

5 by a ring 7, which is spring-loaded by springs 8, which are n-repsting the bulging of the sheet (loss of stability) in the area of the thickening set, and contributes to the formation of equal quality.

license plate in the zone of formation of thickening. The occurrence of an undesirable influx in front of the deforming roller is prevented by the clamp 4, which, by force of the tracks, moves along the grooves of the time plates pressed against the deforming roller and on the sheet blank. The upright movement of the presser 4 is prevented by the presser 5 and

The CS has a direction; and 6 plts, along the grooves of which the clamp 4 moves in the longitudinal direction together with the deforming roller, while the gap between the base and the bottom surface

-.J5 of clamp 4 remains constant. After rolling and the formation of a thickening on the edge of the sheet, the latter is removed from the plate, cooled, cut, for example, on a guillotine scissors, the remaining 40 billet, which is equal to 3-6% of the initial volume of the material that has been deformed.

The proposed device will expand the possibilities of obtaining thickening on
