Abstract

Steel tubes are cold-drawn in a bench wherein the reducing die is located in front of a sleeve defining with the external surface of the tube to be cold-drawn an elongated tubular confining space which tapers toward the die at an angle of less than 3 DEG . The space is filled with a lubricant at an elevated pressure of up to 100 atmospheres superatmospheric pressure, and such pressure rises automatically to a value exceeding at least 10 times the initial pressure when the tube is moved lengthwise at a speed of up to and in excess of 300 meters per minute. The rise in pressure of confined lubricant is due in part to friction between the lubricant and the external surface of the tube and suffices to insure that the moving tube remains out of mechanical contact with the die. A similar forwardly tapering confining space for reception of a pressurized lubricant can be provided between the internal surface of the tube and a confining member which is connected to and located behind a floating mandrel. The thus treated tube can be subjected to one or more additional cold-drawing treatments to reduce its outer diameter from 8-35 millimeters to about 3 millimeters and its wall thickness from about 3.5 millimeters to about 1 millimeter.
