Abstract (en)
[origin: EP0652100A1] 2.1. The tilt of the slide, caused by eccentric loading, on the mechanical presses is taken into account upon working-in of the die, the presses not being available from time to time for production tasks. Consequently, the dies are often worked in on a hydraulic work-in press. When using the dies on the production presses, time-consuming correction work is often still required as a result of the different load-dependent tilt of the slide. By virtue of the novel method, the tilting behaviour of production presses with different spring rates is intended to be simulated on a hydraulic work-in press. 2.2. The hydraulic work-in press contains at least four counter-retaining cylinders which act counter to the operating movement of the slide. In order to simulate the load-dependent tilt of the slide of mechanical presses, the oil pressure in the counter-retaining cylinders is regulated such that the slide is in each case counteracted at least in the operating region - starting from the tilt of the slide determined - by so much force that the tilts of the slide in the x-axis and y-axis are restricted to values which are given by parameterisable tilting characteristics Mx = f1 (kx) and My = f2 (ky). <IMAGE>
