CS236938B1 - The method of drawing a micro-wire - Google Patents

Abstract

The invention relates to rolling and drawing, in particular, microwire from various metals and alloys, including low-ductility ones. The aim of the invention is to improve the quality of microwire from low-ductility materials by changing or completely eliminating the twisting of the blank in the working area of the die. The existence of the invention lies in the fact that the blank is rolled along the arc of a circle, the center of which is located in the drawing axis, while the inlet and outlet cones of both parts of the die are in the shape of an arc. The invention can be implemented in the radioelectronic, instrumentation and electrical engineering industries.

Description

(54) Microwire drawing method

The invention relates to rolling and drawing, in particular, microwire from various metals and alloys, including those with low ductility.

The aim of the invention is to improve the quality of microwire from low-ductility materials by changing or completely eliminating the twisting of the blank in the working area of the die.

The existence of the invention lies in the fact that the semi-finished product rolls along the arc of a circle, the center of which is located in the drawing axis, while the inlet and outlet cones of both parts of the die are in the shape of an arc.

The invention can be implemented in the radioelectronic, instrumentation and electrical engineering industries.

Claims (1)

Object of the invention A method for drawing a micro wire comprising reversing a blank with a deformation perpendicular to the drawing axis while moving through a die, characterized in that in order to improve the quality of the micro wire by reducing its twisting, the blank is rolled according to the arc of a circle centered in the sweep axis. i. Apparatus for carrying out the method of item 1, comprising a die comprising two portions each having an inlet and an outlet cone and having a gap therebetween, characterized in that the inlet and outlet cones of both portions are in order to enhance the quality of the microwire. the die is formed in the form of an arc. Recognized by the invention based on the results of expertise carried out by the State Committee for Inventions and Discoveries of the USSR, Moscow, SU
