Abstract
The utility model discloses a main driving mechanism of a hydraulic servo press, which comprises a hydraulic servo system and a symmetrical multilink structure, wherein the hydraulic servo system is placed on an upper crossbeam, a hydraulic executive component is connected on the upper crossbeam, one end of the hydraulic executive component is connected on a driving slide block, a symmetrical link mechanism is hinged on the driving slide block, the upper crossbeam and a main slide block, the main slide block is driven to move up and down by the driving slide block through the symmetrical link mechanism, and the input force of the driving slide block is transferred into the output force of the main slide block after being amplified. The utility model has the advantages of energy saving, material saving, high efficiency, flexibility, controllability and the like and can replace a traditional mechanical press and an ordinary oil press step by step through popularization and use.
Description
Technical field
This practicality relates to a hydraulic servo forcing press, the especially main drive gear of hydraulic servo forcing press.
Background technology
At present, because hydraulic system has big and corresponding fast, the advantage such as acceleration capacity is strong of power weight ratio, hydraulic press occupies bigger proportion in pressure forming machinery.But common hydraulic press speed is non-adjustable, has limited the moulding process of part.。
Existing mechanical forcing press main transmission mostly is the knuckle press that adopts common electric machine to drive, and employing flywheel storage power is used brake and clutch is braked and clutch.The power consumption of the forcing press ubiquity of this form is high, maintenance difficult, shortcoming such as noise is big, and the curve movement of slide block is non-adjustable.
At present, occurred adopting hydraulic cylinder directly to be connected the forcing press of driving with slide block, the forcing press of this mode, the power of sending when a high position is the same big with near the lower dead center power, less pressure can only be provided, not meet common, common pressure processing craft demand.
Summary of the invention
The utility model proposes the main drive gear of hydraulic servo forcing press, input power less on the hydraulic actuator realizes bigger power output by the amplification of the power of symmetrical linkage, and can effectively prevent unbalance loading, thereby with the symmetrical linkage of large-power hydraulic system and power amplification and fast response accurately the servo-drive system of control realize perfect adaptation, have energy-conservation, material-saving, efficient, flexible, controlled advantage.
For this reason, the technical solution of the utility model is: the main drive gear of hydraulic servo forcing press, comprise Hydrauservo System and symmetrical multi-link structure, Hydrauservo System is placed on the entablature, hydraulic actuator is connected on the entablature, one end of hydraulic actuator is connected and drives on the slide block, the symmetry linkage is hinged on and drives on slide block, entablature and the master slider, drive slide block and drive master slider by symmetrical linkage and move up and down, and the input power that realizes driving slide block is transmitted after amplifying and is the power output of master slider.
Further qualification to technique scheme: Hydrauservo System can adopt valve control servo-drive system or pump control servo-drive system.
Further qualification to technique scheme: the rated pressure scope of hydraulic actuator is 1MPa-100MPa, and the metered flow scope is 1L/min-2000L/min; The movement length scope of symmetry linkage is 100mm-2000mm.
Beneficial effect: hydraulic actuator of the present utility model is connected and drives on the slide block, drive slide block and move up and down, and then the die that drive is contained on the slide block is finished kinds of processes such as bedding-in, debugging mould and flexible punching press by the symmetrical multi-connecting-rod mechanism drive master slider that connects thereon.Compare with traditional oils press and punching machine, the utility model patent has following characteristics: (1), main transmission effectively combine Hydrauservo System and symmetrical multi-connecting-rod mechanism, the symmetry multi-connecting-rod mechanism amplifies the output pressure of hydraulic actuator, and can effectively prevent unbalance loading.(2), in the transmission system of this form, the speed of hydraulic actuator and final slide block output speed are non-linear relation, realize the adjustable arbitrarily of the closed-loop control of slide block positioning accuracy and ram speed curve by the control software of press motion control system special use.
