Problems solved by technology

Here, however, the pump is arranged on both sides of the pump motor, so that on the one hand an expensive double-head motor must be used and on the other hand the pump must be driven in different directions of rotation
It is also disadvantageous economically

Embodiment Construction

[0031] figure 1 A schematic diagram of a hydraulic system 1 according to the invention is shown. Four pumps 4 are arranged on the shaft 3 . In this case, the pump 4 is designed as a regulating pump, in particular as an axial piston pump (see Figure 5 ). In this configuration, the pump motor 2 is arranged at the left end of the shaft 3 . The pump motor 2 can be decoupled from the pump 4 by means of a clutch device 6 .

[0032] In this case, the control or regulating device 5 is provided for regulating the deflection of the pump motor 2 and the pump 4 . The control or regulating device 5 monitors the torque exerted by the pump motor 2 on the shaft 3 . This momentary moment constitutes the momentary drive moment of the shaft 3 .

[0033] The instantaneous drive torque can also be calculated, for example, from the product of the pump deflection and the instantaneous pressure of each individual pump 4 . This instantaneous drive torque can thus be the sum of the individual d...

Abstract

The invention relates to a hydraulic system for a molding machine, comprising a pump motor (2), a shaft (3) connected to an output of the pump motor (2), a plurality of pumps (4) driven by the shaft (3) and a control device (5) Control or regulation of the pump motor (2) and / or for controlling or regulating at least one deflection of at least one of the plurality of pumps (4), wherein a maximumdrive torque of the shaft (3) is less than a maximum torque of the pump motor (2) and that the control or regulating device (5) is designed to control or regulate the pump motor (2) and / or the at least one deflection such that a momentary through-drive torque of the shaft (3) does not exceed the maximum drive torque of the shaft (3). The invention also relates to a forming machine including the hydraulic system.

Description

technical field [0001] The invention relates to a hydraulic system for a forming machine according to the features of the preamble of claim 1 and to a forming machine comprising such a hydraulic system. Background technique [0002] Here, the molding machine is understood to mean an injection molding machine, a die-casting machine, a stamping machine and the like. [0003] Such a hydraulic system comprises a pump motor, a shaft connected to an output of the pump motor, a plurality of pumps driven by said shaft, and a control or regulating device for controlling or regulating the pump motor or said At least one biasing device for at least one pump of the plurality of pumps. [0004] In this case, in the prior art, the pumps are mostly arranged modularly against one another, so that the individual components in the pump together form the entire shaft. Due to the deflection devices of the pumps on the market, it is generally not possible to arrange more than three pumps again...
