1379342 Shaping presses SOC NATIONALE INDUSTRIELLE AEROSPATIALE 25 May 1973 [8 June 1972] 25150/73 Heading B3E A press for shaping elongate metal panels P comprises a press frame A, supports H disposed on either side of the press frame for the panels, and a supporting beam C for a carriage (97), Fig. 17 (not shown), having a depending bracket Ea, Eb for gripping an end of the panel, arranged either side of the press frame. The press frame also includes a punch carrying carriage B. A table H includes vertically adjustable rollers I for conveying the panels and brackets J which have gauges K for checking the shaping of the panels. A gripping member M is utilized in combination with grippers G of the carriages (97) for turning over the panels. The position of the movable members of the press can be determined and displayed on a board N to allow automatic displacement of the members. The punch carrying carriage B is displaceable along rails 5 by a chain 23 driven by a motor 24 via transmission 25 and the tool carrier 17 is vertically displaced by a jack 13. The too carrier 17 has at least one U-shaped member 19 and preferably a pair of member 20 which can be orientated at various angles in relation to the frame to co-operate with rails 52 disposed on the table 3 in members 50, 51, Fig. 10 (not shown). Vertical displacement of the tool is measured by a sensor 33 which transmits the information to a coding device 34 for display on board N. A coder (36), Fig. 3 (not shown), evaluates the displacement of the carriage B along the frame A. The members 19, 20 are adapted to receive detachable rails (38), Fig. 9 (not shown), whose outer surface is curved for the shaping of the panels. In operation, when a panel P is placed on the rollers I of one of the two tables H a dog-type clutch (111), Fig. 18 (not shown), is actuated to enable motor (101) to cause gripping of the panel by member (Gb) of bracket Eb and then by member (Ga). The two brackets are moved simultaneously in the same direction, at the same speed, to the press frame and the panel is stopped when the position of the panel as determined by a coder (119) coincides with measurements on the board N, whereupon shaping takes place. During the shaping of a first panel, data can be recorded to enable similar panels to be shaped identically. In order to check the shapes the rollers I can be lowered so that the panels P contact the gauges K.
