Abstract

1,172,243. Stretching; upsetting. D. F. SALT. 25 May, 1967 [10 March, 1966], No. 10517/66. Headings B3E and B3H. Apparatus for stretching or upsetting sheet metal comprises pairs of jaws 14, 15 adapted to operate against opposite faces of the metal, the jaws 14, 15 of each pair being urged to move relatively to each other while maintaining parallelism of their working faces, with a force which is a function of the loading force with which they are applied to said faces, each jaw being supported by at least two resilient doublecantilever members 12, 13 inclined to the loading force. The jaws 14, 15 are each connected to a common base 10 by two pairs of spring blades 12, 13 secured to the jaws and base by wedges 16, 17 and screws 18. Alternatively, the blades may have an interference fit into slots in the jaws and the base. The working faces of the jaws are provided by inserts 19, 20 of steel or nylon. A thin rubber sealing strip 21 is provided between the jaws or a spring-loaded work-supporting wedge may be inserted between the jaws. Another embodiment is described for stretching the metal, Fig. 6 (not shown).
