摘要
The hydraulic press of the invention has two slides 2, 3 which can move with respect to each other under the action of actuating rams 4a, 4b. These slides comprise a slide core and a slide square, in contact with the forming tool. At least one of the slide squares consists of a plurality of segments 14a, 15a, 15b, 15c, 14b. The ends in contact of two juxtaposed segments are supported by a compensating ram 17a, 18a, 18b, 17b, which bears on the slide core. The press also includes means for measuring the deformations of the slides, comprising reference beams 9; 10 and sensors 11a, 11b, 11c, 12a, 12b, 12c measuring the distance between the beams and the said slide. According to the invention, the measured deformations are compensated for by acting independently on each compensating ram. IMAGE
