摘要： The invention relates to a method for shaping an essentially flat-surfaced blank (10) to form a shell body (34), comprising the following steps: forming at least one flat-surfaced, buckling-stable insert (12) which is adapted to form, dimension and deformation properties of the flat-surfaced blank (10); forming a blank (14) to be deformed and at least one buckling-stable insert (16, 16′, 16″) to be deformed from the flat-surfaced blank (10, 10′) and the at least one flat-surfaced buckling-stable insert (12, 12′); placing and clamping the blank (14) to be deformed and the at least one buckling-stable insert (16, 16′, 16″) relative to one another and deforming the blank (14) together with the at least one buckling-stable insert (16, 16′, 16″) to be deformed in order to form the shell body, using at least one forming tool (32) that acts upon the front or inner side (20) of the blank (14) to be deformed or the at least one insert (16) to be deformed which is provided as a support. The invention also relates to the use of said shell body (34) to produce rotationally symmetric and/or not rotationally symmetric shell-shaped components.

摘要： A spin forming process and apparatus is disclosed. A workpiece (e.g. sheet metal) is rotated with respect to a forming roller which bears against one of the outer and inner surfaces of the workpiece to deform the workpiece towards a required shape. First and second support rollers bears against the opposite surface of the workpiece. Computer control of the positions of the forming roller and the first and second support rollers allow non-axisymmetric shapes to be manufactured by spin-forming.

摘要： A plate member (10) is mounted on a supporting frame (11). The periphery of the plate member (10) is firmly secured by a clamp (12) and a concave die-shaped lower pushing member (13) is caused to rise from below. The lower pushing member (13) is provided with a forming concave area (15) and a forming convex area (16). Disposed above the plate member (10) is a bar-shaped upper pushing member (20) which is lowered to push against the plate member (10). In such a condition, the plate member (10) is caused to rise together with the lower pushing member (13) and move in the directions of X and Y to form convex areas (17) and (18) within the forming concave area (15) and the forming convex area (16). The upper pushing member (20) is provided with a main body (21) of high rigidity and a flexible member (22). The flexible member (22) is formed in a hemispherical shape and made of material more elastic than the main body (21) which is made of hard polyurethane or the like, thereby making spherical contact with the plate member (10).

摘要： A process and a device for metal spinning a blank into a formed part, especially into a vessel bottom, are described, which can be used for forming materials including materials which are difficult to deform, with high dimensional accuracy and/or high degrees of deformation. For attaining this object, the blank is clamped on its circumference and forced freely, i.e. without using a spinning chuck, into a clearance by means of a motion-controlled spinning tool until its finished dimension is reached.
