Abstract
A cold flow unit for metal wire is disclosed having at least three successive rollers, wherein the metal wire is trained over a part of the roller periphery such that at the transition of the metal wire from one roller to the subsequent roller the transition distance between the points of contact is less than 5 times the metal wire diameter. A device is disclosed for processing metal wire, having a roller cassette and subsequent thereto at least one such cold flow unit, or having at least two successive such cold flow units.
Claims11
A cold flow unit for treating a metal wire, comprising at least three successive rollers and a rotation speed control connected to each of the rollers,
- wherein the rotation speed controls are configured to control roller rotation speed for each of the respective rollers subject to a desired deliverv speed of the metal wire,
- wherein the rollers are configured such that the metal wire is trained over a part of a roller periphery such that at a transition of the metal wire from one roller to a subsequent roller a transition distance between the points of contact is less than five times a diameter of the metal wire, and
- wherein the metal wire is stretched between the rollers such that tension in the metal wire decreases, tensile strength of the metal wire increases and ductility of the metal wire increases.
A device for processing metal wire, comprising:
- a roller cassette and subsequent thereto at least one cold flow unit having at least three successive rollers and a rotation speed control connected to each of the rollers,
- wherein the rotation speed controls are configured to control roller rotation steed for each of the respective rollers subject to a desired delivery speed of the metal wire,
- wherein the rollers are configured such that the metal wire is trained over a part of the roller periphery such that at a transition of the metal wire from one roller to a subsequent roller a transition distance between the points of contact is less than five times a diameter of the metal wire, and
- wherein the metal wire is stretched between the rollers such that tension in the metal wire decreases, tensile strength of the metal wire increases and ductility of the metal wire increases.
A device for processing metal wire, comprising:
- at least two successive cold flow units each having at least three successive rollers and a rotation speed control connected to each of the rollers,
- wherein the rotation speed controls are configured to control roller rotation speed for each of the respective rollers subject to a desired delivery speed of the metal wire,
- wherein the rollers are configured such that the metal wire is trained over a part of the roller periphery such that at a transition of the metal wire from one roller to a subsequent roller a transition distance between the points of contact is less than five times a diameter of the metal wire, and
- wherein the metal wire is stretched between the rollers such that tension in the metal wire decreases, tensile strength of the metal wire increases and ductility of the metal wire increases.
