Title: Large area accurate plastics press - has hydraulic layout with high speed low load toggles and pressure system with device s to detect and correct deviations from parallelism
Inventor: HARTUNG WOLFGANG
IPC: B30B15/24
Filed: 1990-11-23
Abstract: An hydraulic press with short stroke and high accuracy synchronisation control is partic intended for the prodn of large size plastic sheets. It has a toggles system for quick action idle movements, hydraulic cylinders to produce the working pressure and separate releasing cylinders; it has synchronising cylinders connected to the rams when in action, these cylinders being connected together diagonally in pairs. In action the rams are connected to four gauges which measure deviations from the parallel of rams and platens; the system also has a control for the differential loading of individually synchronising cylinders to compensate for deviations. Four single-action hydraulic synchronising cylinders with short stroke are on the fixed platen and four other synchronising cylinders with identical effective piston areas are located above the press cylinders with their piston rods attached to the plunger rams; the space between the ram and pistons of the lower synchronising cylinders in the upper end position of the ram  equals the stroke of the toggles system; when the toggles system is fully extended the ram is held firmly between the upper and lower synchronising cylinders. The lines connecting the diagonally opposite upper and lower synchronising cylinders are linked to respective servo-valves whose pressure connection on the inlet side is linked to a pressure regulator, its control member being regulated conventionally by an electronic comparator and estimating device by the deviations from parallelism detected by the relevant fine controls systems. ADVANTAGE - The system confines deviations from the parallel to micrometres.
