摘要： A control system for forming a tapered structure includes a sensor providing feedback for a machine for forming a tapered structure including at least three rolls having at least one bend roll and at least two guide rolls. The guide rolls may include rollette banks having a plurality of rollettes. The machine may also include an adjustment mechanism to position at least one of the rolls, where a diameter of the tapered structure being formed is controlled by relative positions of the rolls. The machine may also include a joining element to join edges of a stock of material together as it is rolled through the rolls to form the tapered structure. The control system may also include a controller to receive feedback from the sensor and to send a control signal based on the feedback to the adjustment mechanism for positioning at least one of the rolls.

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.

The mandrel (11) being mounted between support frame ends (24, 25) and on a single pressure roller (15) mounted beneath the mandrel (11) and adapted to contact the surface of the plate and apply a squeezing force against the plate and mandrel (11) during a rolling operation, the pressure roll (15) being laterally movable relative to the center-line of the mandrel depending upon the location of the gripper rib (14) in the region of the roller (15) so as not to foul the gripper rib (14) yet applying said squeezing force to said plate as required. A mandrel (11) having an adjustable taper angle is disclosed as an adjustable mandrel support member (2, 25) and mandrel journal (26) to accommodate variable mandrel diameters and angles or taper.

摘要： An apparatus for tapering a tube having a frame, a tube receiving end connected to the frame, a variable-orifice die arranged so as to be movable relative to the frames, and an axial tension cylinder connected to the tube receiving end so as to apply tension forces to the tube. The variable-orifice die includes a stand having a housing and a plurality of die segments arranged within the housing. The die segments contain a circular groove of varying radius. The die segments define an orifice having an entry plane and an exit plane. The exit plane and the entry plane are offset from the plane of rotation of the die segments. The orifice is truly round in a plane parallel to and offset from the plane of rotation. A motion control processer is interactively connected with the die stand and with the axial tension cylinder for controlling a position of the axial tension cylinder relative to a rate of reduction of the diameter of the tube.

摘要： A conical tubular member has inwardly directed profilings (2, 2', 3, 3'), formed over a core with grooves arranged to receive the profilings (2, 2', 3, 3') and having a conical shape substantially corresponding to the internal shape of the member to be manufactured. Hydraulically and/or pneumatically applied force is divided over the surface of the tubular member by at least one flexible pressure applying member arranged surrounding the tubular member, and the member is thereafter formed into a conical shape corresponding to the shape of the core, the reduction in diameter of the member being compensated for by means of a change in the shape of the profilings (2, 2', 3, 3'). The member is advantageously manufactured from a material having through perforations, or a wire mesh material.
