摘要： Forming methods of one-piece weldless wheels made of metal sheets including the steps of rolling, forming a primary wheel rim and a primary wheel disc, roll forming, compressing and shaping, in order to obtain one-piece weldless wheels. The methods can form weldless wheels by rolling, cold roll forming and cold extruding, which can reduce energy consumption by 45-55% and cut down material cost by 5-15% while improving strength of the wheel by 20-30%. A wheel with different thicknesses can be formed by the methods and can meet the requirements on mechanical strength. The methods can improve the precision of the wheel and minimize the swing value and jerk value. The wheel produced is safer, and the regular air tight test on the wheel is not necessary.

摘要： A spinning forming device includes: a rotating shaft that rotates a plate to be formed; a processing tool that presses a front surface of the plate while being moved outward in a radial direction of the rotating shaft; and a heater that is moved so as to be located on the same circumference as the processing tool and locally heats the plate by induction heating. The spinning forming device further includes a cooling device that cools the front surface of the plate.

摘要： The profile shape of the vessel body and of handle portion is formed from a single sheet of metal to create a flat by cutting, stamping or blanking. An opening is created in the handle portion to reduce heat propagation. The shape of the pan body is formed by spinning with the flat handle portion. The handle is formed by creating three-dimensional contours in the handle portion of the blank. The neck portion has a flat section adjacent the pan body followed by sections of different curvature. One section of the neck portion has a deeply curved cross-section. That neck portion transitions to the hand grip portion which has a reduced curvature, particularly toward the unattached end of the handle. The neck portion may have a “W” cross sectional shape. The handle grip portion may have a “U” shaped cross-section for comfort.

摘要： According to a spinning forming device, while a plate is rotated by a rotating shaft, a transform target portion of the plate is pressed by a processing tool and locally heated by a heater that performs induction heating. The heater includes a coil portion having a doubled circular-arc shape and is inclined by an inclining device relative to a direction from the rotating shaft toward the processing tool. A measuring unit measures distances each from the coil portion to an outer peripheral original portion of the plate at a plurality of measurement points distributed in a circumferential direction of the rotating shaft. A controller controls the inclining device based on a measurement result of the measuring unit such that an angle difference between the coil portion and the outer peripheral original portion becomes not more than a predetermined angle.

摘要： In a spinning forming method, a plate including a peripheral portion at which a ring-shaped projection is provided is used, the projection projecting in a thickness direction of the plate. Further, while rotating the plate, a transform target portion of the plate is locally heated, and a processing tool is pressed against the transform target portion to transform the plate. According to this configuration, a heat capacity of the peripheral portion of the plate can be increased. With this, when heating the vicinity of the peripheral portion of the plate, the peripheral portion can be prevented from becoming high in temperature. As a result, deformation of the peripheral portion of the plate can be suppressed.

摘要： A spinning thickening forming method is a method of, while rotating a plate including a center portion fixed to a fixing jig, increasing a thickness of a peripheral portion of the plate. Specifically, while locally heating the peripheral portion of the plate such that at least a portion of the plate which is adjacent to the fixing jig maintains stiffness, a forming roller is pressed against the peripheral portion of the plate to compress the peripheral portion in at least a direction perpendicular to a thickness direction of the peripheral portion.

摘要： A tube flanging method includes the steps of: disposing a tube such that an edge thereof is exposed to the outside of a forming mold while the tube is inserted into the forming mold; applying an external force to the exposed edge of the tube to expand the exposed edge of the tube; applying an external force to the expanded edge to bend the expanded edge toward an outer surface of the forming mold; and applying an external force to the bent edge to form a flange, the flange having a linearly integrated cross section and being perpendicular to the longitudinal direction of the tube. With this configuration, it is possible to bend the tube to form the flange at a uniform thickness.

摘要： The invention relates to a method and a forming machine suitable for manufacturing a product having various diameters from a workpiece, such as a metal cylinder or plate, in which the workpiece is clamped down in a clamping device, the workpiece and a first tool are rotated about an axis of rotation relative to each other, the workpiece is deformed by means of said first tool by placing the tool into contact with the workpiece and moving the workpiece and/or the tool in a direction along the axis of rotation. At least a second tool is placed into contact with the workpiece at a position behind the first tool, seen in the working direction, and the workpiece is also deformed by means of said second tool. Thus, parts of the workpiece that have been deformed by the first tool are deformed by one or more subsequent tools practically immediately.
