Abstract
The method of the invention includes forming a plate and deforming, by ultrasonic forging, a plate side located between the conical surfaces (34, 35) of strikers (2, 3) for the purpose of forming a wedge-shaped edge on the plate (1). The strikers are rotated around their longitudinal axes (L1, L2). The device of the invention is provided with a drive for rotating the strikers (2, 3). On the working surface of the striker (2, 3) a recess is made, the generatrix of which corresponds to the form of the wedge-shaped edge surface. The invention enables to shorten the time of treatment and improve the quality of the cutting edge surface.

1) Method of making a cutting edge (31) of a cutting device (32), said cutting device (32) comprising a plate (1) with a plate region (1a) adjacent to an edge (33),
- wherein at least a portion of the plate region (1a) and the edge (33) are positioned between two strikers (2, 3) of an ultrasonic forging device,
- wherein the cutting edge (31) is formed from the plate region (1a) and the edge (33) by simultaneously moving the plate (1) in a direction parallel to the edge (33) and essentially orthogonal to the longitudinal axes (L1, L2) of the strikers (2,3) during operation of the strikers (2,3), and
- wherein the strikers (2,3) are rotated around their longitudinal axes (L1, L2) during operation.
11) Device for making a cutting edge (31) of a cutting device (32) from a plate (1), comprising:
- a) two strikers (2, 3) connected to sources of ultrasonic vibrations (13, 14), the strikers (2,3) arranged one opposite the other and having cone-shaped working surfaces (34,35),
- b) means to move (10) the plate in directions parallel to the edge (33) of the plate (1) and transversely to the longitudinal axes (L1, L2) of the strikers (2,3), and
- c) means to rotate (4,5) the strikers (2,3) around their longitudinal axes (L1, L2) simultaneously with movement of the plate (1) during operation of the strikers (2, 3).
16) A method of making a cutting tool edge (31), comprising deforming a plate end (33), as located between the conical surfaces (34,35) of strikers (2,3), by ultrasonic forging, with simultaneously moving the plate (1) relative to the longitudinal axes (L1, L2) of the strikers (2,3) in the transverse direction for the purpose of forming a wedge-shaped edge (31) on the plate (1), characterized in that when deforming a side (1a,33) of the plate by ultrasonic forging the strikers (2,3) are rotated around their longitudinal axes (L1, L2).
24) A device for making cutting tool edges (31), comprising strikers (2,3) connected to sources of ultrasonic vibrations (13,14), arranged one opposite the other, and having working surfaces (34,35) made cone-shaped, and a mechanism (10) made so as to ensure the plate movement between the striker working surfaces (34,35) transversely relative to their longitudinal axes (L1,L2) and installed with the possibility of deforming a plate side (1a,33) characterized in that a drive (4,5) is added, being made with the possibility of rotating the strikers (2,3) around their longitudinal axes (L1,L2).
32) A striker (2,3) for ultrasonic making of a cutting tool edge (31), which has the working surface (34,35) made cone-shaped and intended for deforming a plate side (1a,33) by ultrasonic forging for the purpose of producing a wedge-shaped blade (32), characterized in that on the cone-shaped working surface (34,35) a recess is made, the generatrix of which is made corresponding to the surface form of a wedge-shaped edge (31).
