Abstract

932,228. Stretch-forming; bending. CYRIL BATH CO. April 4, 1962, No. 12848/62. Class 83 (4). Apparatus for forming metal stock in which the stock is subjected to an operation which produces tension loads in it of an order in the region of the elastic limit of the material comprises a side fore die 17, about which the stock S is wrapped, mounted on a table 2 rotatable about a predetermined axis and a gripping head 14 operable to grip the end of the stock remote from the die for endwise tensioning of the stock, the gripping head having gripping means for the stock in which the latter is bent about a part of the head so that the end portion S<SP>1</SP> of the stock being gripped by the head is held transversely to the line joining the point of contact of the stock and the die 17 and the part of the head 14 about which the stock is bent, such that the part 25 of the bend in the stock can become coincident with the point of contact of the stock and the die. The gripper head 14 is pivotably carried at 15 by a yoke 13 slidable along a guide 10 on a carriage 3 swing- able about an axis 4. Tension is maintained in the stock S by a piston 7 on the carriage 3. The end S<SP>1</SP> of the strip S is held between a jaw 23 on the head 14 and a jaw 24 urged against the jaw 23 by piston means 27.
