ROLLER DRAW PLATE Russian patent published in 2022 - IPC B21C3/08 

FIELD: metal working.

SUBSTANCE: invention relates to roller apparatus for drawing round wire and shaped profiles. Roller draw plate for producing round and shaped profiles comprises a sequence of horizontal and vertical pairs of working rollers connected to mechanisms for the radial and axial adjustment thereof and located in a body made of two half-frames. The working rollers in each pair are shaped as a two-stage cylinder, wherein one stage with a radius R is larger than the other stage with a radius r; strands for the corresponding gauges are cut on the cylindrical surface of the stages; and the height H of the stage of each roller is equal to the difference between the radii R and r, while also equal to the distance between the axes of the gauges formed by the corresponding strands. Herein, the cylindrical surface of the roller stage with radius R comes in contact with the cylindrical surface of the stage of the roller with radius r.

EFFECT: possibility of multistrand process of drawing simple shaped and round wire from a round workpiece, and reduced time for reconstructing the roller draw plate when switching between profile sizes in single-strand drawing.
