The invention relates to the rolling and drawing of metals. The microwire manufacturing method according to the invention is characterized in that a microwire blank (1) is rolled during the drawing process in opposite directions relative to the drawing axis (B--B). The blank (1) is rolled over the same distance equal to at least one half of its circumference. The method is carried out with the aid of a device comprising a body (3), a die (4) and a mechanism for drawing wire through the die (4). The die (4) is composed of two parts (5 and 6) which interact with the blank (1) as the latter is drawn between them. Each of the die parts (5 and 6) has a working surface (8). According to the invention, the parts (5 and 6) of the die (4) are secured in the body (3) so that they can be set in synchronized reciprocating motion in parallel planes. The working surfaces (8) of both parts ( 5 and 6) of the die (4) are flat and parallel with each other and the drawing axis (B--B).
A device for manufacturing microwire comprising:
A device of claim 5, wherein the walls of the body, perpendicular to the working surfaces of the die parts, are movable in a plane extending at a perpendicular to the working surfaces of the die so as to vary the gap between the working surfaces.
A device comprising a body and a die composed of two parts secured in the body and interacting with at least one pair of microwire blanks drawn between them, the blanks being symmetrically spaces over a circumference, each of the die parts having an entry surface, a working surface and an exit surface, the device further containing means for drawing wire through the die and a means to control the gap between the die parts, wherein the data parts are coaxially arranged in the body so that they can be set in synchronized reciprocating motion in parallel planes, the external die part being a bushing whose inner surface is formed by the entry surface, the working surface and the exit surface which are all curvilinear, the internal die part of the die being formed by a cone-shaped surface and being movable in the axial direction, the working surface of the external die part being equidistant from the cone-shaped surface of the internal die part.
