摘要： A method for producing hollow profiles provided with different cross sections along the length thereof includes shaping the profiles in a die from one piece of cut metal sheet. According to said method, a convex or concave rounding produced on the edges of a longitudinal section results in material excess or material shortage in the transition regions, thereby preventing the material thinning or thickening in said transition regions during forming.

摘要： A method for producing highly dimensionally accurate, deep-drawn half shells with a base region, a body region and a flange region, includes firstly forming a pre-formed half shell from a blank and then shaping the pre-formed half shell into a finally formed half shell, wherein the pre-formed half shell has excess blank material due to its geometric shape and wherein, owing to the excess material during the shaping of the pre-formed half shell into its final shape the half shell is compressed into the finally formed half shell by at least one further pressing process. The method requires that the pre-formed half shell has excess blank material in a transition region between the body region and flange region.

摘要： A method for producing low-springback half shells made of a metal, in particular steel or a steel alloy, includes drawing in at least one drawing die a blank, such that the blanks have flange regions on the deep drawn body after the deep drawing. The flange regions are shaped by upsetting a corner substantially perpendicularly to a wall of the deep drawn region of the blank and the flange regions are subsequently trimmed in a shearing die, such that half shells without margins are produced.

摘要： A bending device is described for thin-walled metal tubes (R) made of a straight tube guide (1), a core template (2), which adjoins the tube guide (1) and is pivotable in relation thereto, having a connection strip (3), and a mandrel, having a mandrel tip (4), which is flexible in the region of the core template (2), and a mandrel shaft (5), which adjoins the mandrel tip (4) and is rigidly connected thereto and is axially fixed (1) in the tube guide. In order to support the metal tube (R) to be bent over its entire surface on the inside in the active bending region during the bending procedure, the flexible mandrel tip (4), which comprises a radially incompressible solid cylinder made of elastomer, extends only over the starting section of the bending curve, where the bending procedure occurs. In order to pull the metal tube (R) to be bent over this mandrel tip (4), the tube is clamped in the region of the core template (2) for a short length using a spherical clamping head (7) insertable in the metal tube (R), the clamping head (7) being movable in relation to the mandrel tip (4) in the pivot region of the core template (2) and being attached to a traction means (6) implemented as a retrieval element.

摘要： The invention relates to a bending mandrel for a bending device and also to a bending method for pipes, more particularly pipes which have a large diameter-to-wall thickness ratio and are to be bent by a small radius, for example, of the order of magnitude of the pipe diameter. To this end use is made of a bending mandrel (5, 6) to whose rigid head (5) assembly (6) of springy sheet metal lamellae (6a, 6b) is attached to improve the bendability of the bending mandrel (5, 6) while maintaining a satisfactory supporting action, the lamellae (6a), with the exception of the outer lamellae (6b), having window-like cutaway portions (6c).
