摘要： There is provided a method of manufacturing a variable wall thickness steel pipe with a hollow tubular raw pipe. The method of manufacturing a variable wall thickness steel pipe includes locking the raw pipe in a die by thrusting a plug into the raw pipe from an one end side, so as to expand an outer shape on the one end side in a state, where the raw pipe is disposed inside the die and movement of the raw pipe in a longitudinal direction is restricted; and performing ironing in which an inner shape of the raw pipe is expanded while the outer shape is maintained so that a thin portion is formed by further thrusting the plug toward the other end side of the raw pipe while the locked state of the raw pipe is maintained, whereas the restriction on the raw pipe is relaxed.

摘要： A tube for use in conjunction with a deep drilled hole comprises a light metal tube made of an aluminium alloy, having sections of different wall thicknesses arranged in the longitudinal direction of the tube and a respective coupling at each end for connecting the tube to a further tube, wherein the light metal tube is produced from an aluminum alloy containing the following elements: 2.5-5.0 wt. % Cu, 0.2-1.0 wt. % Mg, 0.8-2.0 wt. % Li, max. 0.15 wt. % Si, max. 0.15 wt. % Fe, max. 0.5 wt. % Mn, max. 1.0 wt. % Zn, max. 0.1 wt. % Ti, max. 0.5 wt. % Ag, the remainder being Al and unavoidable impurities. Also described is a method for producing a light metal tube for a tube of this type configured for example as a bore tube. Said method comprises the steps of forming the light metal tube by means of an extrusion method and subsequent solution annealing, then drawing out the extruded tube over the entire length thereof, until the section or sections having the smallest wall thickness are drawn out by at least 2 to 2.5%, and the drawn light metal tube is artificially aged in a subsequent process step at a temperature of between 164° C. and 180° C.

摘要： A method is used to manufacture a drawn tube having a hollow low interior for housing an axle shaft. The method includes the steps of placing a billet into a first die assembly and pressing the billet into the first die to producing a pre-formed billet. The method also includes the steps of moving the pre-formed billet from the first die assembly to a second die assembly and pressing the pre-formed billet into the second die assembly to produce an extruded tube. The method further includes the steps of moving the extruded tube from the second die assembly to a third die assembly and pressing the extruded tube into the third die assembly to further elongate the extruded tube and decrease the thickness of the wall of the extruded tube to of from about 3 to about 18 millimeters to produce the drawn tube having the yield strength of at least 750 MPa.

摘要： A corrugating unit is used which presses a first corrugation into the pipe which is moved in its longitudinal direction through the corrugating device. The spacing between the wave peaks is subsequently reduced, for obtaining a second corrugation, by a clamping unit composed of two separately arranged clamping devices resting against the pipe. The pipe provided with a first corrugation is pressed continuously by the first clamping device against a fixed point realized by the second clamping device, which, in the position of operation, is arranged, in relation to the clamping device, in axial direction behind the first clamping device. Both clamping devices are removed cyclically from the pipe and are moved back into a new position in the opposite direction of the direction of movement of the pipe and, in this new position, again rest in the two different areas against the pipe.

摘要： A radial dimension of a pipe is changed by applying contiguous pipe contacting surfaces of adjacent cam rollers. Pipe contacting surfaces uniformly vary in width of curvatures as distances change between a center of rotation of the cam rollers and the pipe contacting surfaces side walls of the cam rollers are shaped and adjacent. Bevel gear teeth on sloped side walls force all rollers to turn uniformly. Cylinders on a frame surrounding the pipe drive pistons, lever arms and cam rollers that move the pipe wall. Radial forces on the cam rollers hold sloped side walls adjacent, bevel gears engaged and pipe contacting surfaces contiguous. Smoothly deforming a pipe wall inward forms a nozzle sat an end, a restrictor, a pipe closure, a solid rod or a pipe joint. In a joint, outer and inner pipe walls are moved inward respectively beyond and within elastic limits, ensuring tightness.
