摘要:
A process for pressing in which the mold is advanced by gravity or auxiliary actuation means (10). The pressing is actuated by directing liquid flow of a positive-displacement pump (16) to a hydraulic actuating means (10). The pump (16) is connected to a flywheel (22). The liquid flow is directed by closing a first valve means (20). A hydraulic circuit comprises a distribution valve unit (36, 38) connected with the delivery line (19). A plurality of pressure lines (23, 40) are connected with the distribution valve unit (36, 38). A hydraulic pressing apparatus, operates with an open hydraulic circuit (31, 32, 33, 18, 16, 19, 23, 10, 15). The apparatus comprises a flywheel (22) for accumulating kinetic energy, first valve means (20) to discharge the flow of the pump (16) to the tank (31). The invention allows energy savings, high speed and reliability.
摘要:
The present invention relates to a device that is suitable to be used with a pressing apparatus, which includes: a bed plate (10) for withstanding a pressing force that is discharged onto a lower mold (11); a strike plate (16) that is arranged above the bed plate (10), in order to support a lower plunger (13) of the lower mold (11); pusher pistons (18) for lifting the strike plate (16); traction devices (50) to engage the strike plate (16) by traction and disengage it on command.
