摘要： A method for creating a tapered spiral welded conical structure where the overall shape of the cone is first graphically slit axially and unwrapped, and then a series of construction arcs and lines are created to form the edge lines of a strip that can then be wrapped (rolled) to form a tapered conical structure. The edges of the spirally wound strip can be welded together, and a very large conical structure can thus be achieved. Various construction options are presented from a constant width strip to strip made from straight segments. Equations are given for the formation of the strips to enable those skilled in the art of spiral welded tubing to practice the invention.

摘要： Spiral forming methods can be used to join edges of a rolled material along a spiral joint to form conical and/or cylindrical structures. Alignment of the edges of the rolled material can be controlled in a wrapping direction as the material is being joined along the spiral joint to form the structure. By controlling alignment of the edges of the material as the edges of the material are being joined, small corrections can be made over the course of forming the structure facilitating control over geometric tolerances of the resulting spiral formed structure.

摘要： A method for manufacturing a refrigerant guide tube of a heat exchanger and a refrigerant guide tube manufactured using the method and a heat exchanger with the refrigerant guide tube are disclosed. The refrigerant guide tube includes tube body and channels extending through a wall of the tube body. The tube body is formed by a butt joint of side edges of more than one bar-shaped plate materials along the length direction. The method allows forming the refrigerant channels of the guide tube before or during forming the tube body when the method is used to manufacture the guide tube, so as to avoid directly forming the channels on the tube body and make the process of manufacture the guide tube simpler and more convenient.

摘要： A sole configuration for a golf club head that provides the benefits of a sole configuration incorporating a medial ridge design. The medial ridge divides the sole into a toe and heel section. The sole further comprises a first and a second recess in the toe and heel sections respectively, wherein the first and second recesses are downwardly convex thereby allowing for the center of gravity of the golf club head to be positioned lower than in a golf club head having recesses that are downwardly concave. The first recess has a horizontal concavity that is in an opposite direction from the concavity of the second recess.

摘要： A fluting machine and method produce fluted poles. The fluting machine has an aperture means, a carriage, and a track configured so that the carriage can travel on the track toward the aperture means. The carriage has a fluted mandrel for holding a pipe to be fluted. The carriage carries the fluted mandrel and pipe parallel to the track to and from the aperture means at a constant speed irrespective of any fluctuations in driving resistance. The aperture means has a stationary inner part, a rotatable outer head, and a set of rotatory dies. The rotatory dies are circumferentially situated about and perpendicularly extendable within an aperture opening defined by the stationary inner part. The aperture opening is for accepting the fluted mandrel and pipe therethrough. The rotatable outer head causes extension of the rotatory dies within the aperture opening and against the pipe when the rotatable outer head is rotated. The rotatory dies roll along the length of the pipe on the fluted mandrel at constant pressure to thereby produce flutes in the pipe.

摘要： A method for finishing a relatively long metal tubing stock to any desired tapered shape through a single-pass operation. The method is performed with any number of individual swaging units, arranged in tandem each having the identical construction including the same working parts and assemblies. A grooved roll arrangement, associated with the tandem-configured swaging units, is used as a preliminary step to form an initial metal tubing stock into a multiple-stepped shape.

摘要： A method of forming tapered tubes for use as utility poles and the like comprises the steps of making a pair of cuts generally lengthwise of a cylindrical tube on opposite sides of the tube but offset at one end from a common diameter the same distance in the same direction and slanting the cuts so that at the other end of the tube they are on the opposite side of the same diameter, leaving a pair of tube halves having a small arc and a large arc at each end, reversing one of the tube halves to place both small arcs at one end and both large arcs at the other end, welding the halves to each other along the cut edges, and pressing the resultant tube to substantially circular cross section.
