The Effect of Cooling Circuits in a Press Frame on the Resulting Accuracy

Abstract

The constantly increasing demands on product quality place higher requirements on production machines. The machine we investigated is a hydraulic press. Higher accuracy is required and measured on the clamping plates for the tool or on the press frame. The effect of additional cooling in the frame is investigated on a hydraulic press which is intended for production in an industrial production line. The shaping phase of fabric car parts takes place in the mould of this press. The press mould is heated for technological reasons and causes heating of the frame. Heating of the frame causes undesired additional deformation. This paper investigates a press design with additional cooling circuits and its influence on the press work accuracy.
