The invention relates to the processing of metals by pressure and can be used in forging and stamping upon receipt of long panels with ribs.

It is known device, comprising the sequential deformation of the workpiece elements forgings while moving it in the axial direction by means of a set of paired dies [1].

The disadvantage of this technical solution is the inability to apply Emenim attached full load what does not correspond to the structural features of the known device.

The closest set of features is sheet metallocene stamp to obtain products with ribs [2], containing the base, the lower stationary part (matrix), cantilever bending portion (plug) connected to the fixed part can travel from the actuator in the vertical plane. The movement is in an arc of a circle that is drawn around an axis of rotation coincident with the attachment of the movable part to the stationary.

The disadvantage of this device is its applicability to process only sheet blanks of limited length.

The proposed device allows to increase the thickness of stamping blanks, using the rolled plate, and its constructive approach makes possible to obtain panels of large dimensions ad hoc length.

This is achieved by the fact that the stamp containing the base, the stationary part and cantilever bending part connected with the fixed part can travel from the actuator in the vertical plane, equipped with a site of interaction with the actuator placed on svobodnoradikal plane of movement of the movable part, and connected with a fixed part of the hinge with racks mounted on the base, and a shaft freely mounted in the through hole of the movable part and the fixed ends in the uprights, while the movable part is positioned relative to the fixed part with a gap having a vertical plane passing through the axis of rotation of the movable part, an amount not less than the thickness of the product.

The site of interaction with the actuator can be made in the form of thrust bearing mounted on the movable part can move in the direction perpendicular to the shaft, and abutment with the plate associated with the base of the guide columns, and the surface interaction of abutment with the thrust bearing is cylindrical with a generatrix parallel to the shaft.

In Fig. 1 depicts a stamp in the axonometric projection of the slit along the longitudinal axis in the lower working position (without the heel and the toe), and Fig. 2 - section a-a in the lower working position (the dotted line shows the non-operating position of the stamp), and Fig. 3 - section b-B in Fig. 2.

The stamp includes the base 1, the stationary part 2, the movable part 3, stand 4, the shaft 5 with a cylindrical middle part and square ends 6. The movable part 3 vypolnennoi cross member 8, perceiving the load transmitted by forging through the bending section 3, the shaft 5 and 4 hours.

The movable part 3 is posted relatively stationary with a gap 9, the value of which exceeds the thickness of the blade. The stationary part to the movable part forming stream 10 preliminary forming a stream 11 of the extrusion rib stream 12 final moulding. At the free end of the movable part 3 is fixed thrust bearing 13 with a cylindrical recess 14 that communicates with the fifth 15, the plate 16, which is fixed to the traverse of the press (not shown). The thrust bearing 13 mounted in the slots 17 of the movable part 3 and is connected to the fifth 15 by means of two earrings 18 and the fingers 19. The plate 16 is connected to the base 1 by means of guide columns 20 and guide bushings 21.

Stamp works as follows.

The free end of the movable part 3 is raised to its original position (Fig. 2, dotted lines). The workpiece is fed into the gap 9 between the movable and stationary parts in the direction of arrow B (Fig.1). Then, after lowering the plate 16 of the thrust bearing 13 under the influence of heel 15 slides its cylindrical surface 14 of the cylindrical surface of the thrust bearing 13 and moving in the slots 17, is lowered together with the movable part 3.

The stamp is ready for use. The billet is pushed through the gap 9 in the axial direction on the step, the value of which is less than the length of uformowaniu plot, and is 2/3-3/4 the length of the latter.
