摘要： A method for stretch-flow forming, in which a tubular workpiece is arranged around a spinning mandrel, set into rotation and formed by advancing at least one forming roller. A wall thickness of the tubular workpiece is reduced and the tubular workpiece is lengthened, as spinning mandrel use is made of a universal spinning mandrel with different external diameters in the axial direction for producing cylindrical and/or conical and/or cambered hollow parts of different design. during forming the forming roller and the spinning mandrel are moved relatively in the axial direction with respect to the workpiece, and, for the purpose of designing varying diameters and/or wall thicknesses of the workpiece, the forming roller is moved relatively in the axial direction with respect to the spinning mandrel.

摘要： The invention relates to a method for manufacturing finned tubes made of metal, in particular heat exchanger tubes, where at least one continuous strip forming the fins is fed tangentially to a tubular body set into rotational motion, and wound onto it, the side of the strip facing the tubular body is connected to the tube surface by means of a welding device and using a filler material, and the strip to be wound is guided between guide discs just behind the welding area, said discs reaching close up to the tube surface and the welding point. To increase the service life of the guide discs, the guide discs are cooled, specifically with cooling water to which roughly 10% by volume of a welding release agent are added.

摘要： The invention relates to a method and a blank for producing a screw-tube conveyor in the form of a cylindrical rotary tube (110) with an internal screw spiral (120) for conveying and mixing a bulk material. To simplify the method and to create even long screw-tube conveyors with small diameters in an relation to their length, it is proposed according to the invention first to produce a one-piece blank, which comprises a base portion in the basic form of a parallelogram and having laterally mounted fins. In a second method step, the fins are then bent, preferably by 90°, with respect to the base portion. In a third method step, the base portion (112) is then bent along bending lines (115i) in such a way that the base portion forms a helical casing portion (111) of the rotary tube (110) and the previously bent-round fins (122) form segments of the screw spiral (120) arranged inside the rotary tube (110). The invention also relates to a screw-tube conveyor produced in this way.

摘要： A method and equipment for making a needle-fin tube having needle-like external fin parts, and internal fin structure formed by a spiraled spring wire which expands to clamp again the tube in the needle-fin tubes. The wire used to form the internal fin is wound along and around a bar which is moved and rotated along a straight line. The bar is moved inside the needle-fin tube from its one end to the other and the wire is released from the bar to attach to the internal surface of the needle-fin tube under spring force.

摘要： A screw having a field replaceable flight. The screw includes a barrel and a helical flighting that is removably attached to the barrel by a plurality of brackets. The helical flighting includes a plurality of segments, each segment includes first and second opposing faces having an opening extending there though and side edges. The segments are positioned side by side to generally cooperatively form the flighting of the screw. At least one face of each segment includes raised bosses. The raised bosses project perpendicularly outwardly from the face of the segment to form a pocket within which the bracket is received. The segments are removably attached to the barrel by inserting a segment forming part of the flighting within the pocket and then removably fastening the segment within the pocket.
