Abstract

785,630. Flanging; angular bending; stretching; upsetting. ECOLD, W. Oct. 10, 1955 [June 13, 1955], No. 28847/55. Class 83 (4). The edge of a sheet metal blank is bent up by a stretching or upsetting tool, the position of which relative to the plane of the blank is altered as the tool reciprocates to stretch or thicken the edge. A sheet metal blank 2 is clamped to rotatable means carried by a vertically adjustable spindle 4 in a support 1 which is then moved, on rails 5<SP>1</SP>, to a position, and is locked there by bolts 5<SP>11</SP>, in which the edge 8 of the blank lies between an upper part 6 and a lower part 7 of a stretching or upsetting tool. Each part 6, 7 of the tool comprises a pair of jaws which engage the sheet and are moved apart (or together) on the downward stroke of the upper part 6 of the tool to stretch (or upset) the edge. The part 6 is then rapidly reciprocated to effect the stretching (or upsetting) and a bracket 9 which carries the tool is turned in steps, either by hand or mechanically, in a frame 3 about a front edge 10 of the part 7. The edge of the blank is fed through the tool either by hand or mechanically. The support for the blank may be tiltable.
