Abstract
328,890. I. G. Farbenindustrie Akt.-Ges. Oct. 3, 1928, [Convention date]. Tubes; rods and bars. - A metal strip e.g. of magnesium or its alloys is fed in between dies a, b, the top die having a repeated stamping action, and the pass section of the dies varying gradually from flat strip to the finished shape at A-A; Fig. 2 showing the gradual shaping of the metal in successive small steps. To make closed tube &c. sections, e.g. Fig. 5, or partially closed sections, dies a, b, Fig. 6 partly form the section and then a pair of side dies i oscillating about pivots l force the metal around the mandrel k, step by step, as it issues from the first dies. In Fig. 7 a Z- section is formed with a split mandrel k<1>, k<2> both parts of which are fixed to the base m. In Fig. 8 the section - coming from the dies is curved by an adjustabte block c or the dies themselves may be shaped to curve the section. In Fig. 10, stepped profile rings are made from flat strips, the upper die a - stamping the strip against the die b<2> as strip is fed in to profile it gradually, and the strip is then curved by the action of the same top die a against the 2-part rotatable drumlike die b' around which the strip coils itself to form a complete ring. The drum die b' is then split apart to allow the ring to be taken off.
