Abstract
PURPOSE: To keep a slide beam always in parallel with a bed and prevent any possible overload of a parallelism maintaining device, by separately controlling a plurality of press cylinders in accordance with the displacement of the parallelism maintaining link.
CONSTITUTION: A lower bed 1 and upper crown 2 are fixed to slide columns 3, 3'. A slide beam 5 can be moved upward as well as downward along the columns 3, 3' always in parallel with the bed by means of the operation of the press cylinders 4, 4'. A displacement detector 15 is attached to a parallel like 13, which being a part of the device for maintaining said slide beam 5 in parallel with the bed, so as to detect its displacement. An instruction is given from a parallelism controlling device 17 in accordance with a signal wired from the said detector 15 and pressures in press cylinders 4, 4' are separately controlled. When the displacement exceeds the value of a standard signal 19, the downward motions of press cylinders 4, 4' will be stopped and thus the equipment is protected.
