Large-scale double-action thick plate stretching hydraulic machine
Technical field
The invention belongs to the hydraulic machinery technical field, particularly relate to a kind of large-scale double-action thick plate stretching hydraulic machine.
Background technology
In present known large-scale double-action thick plate stretching hydraulic machine, the travelling table of its large press, table top is big, and tonnage is heavy, and existing machine tool and lifting tool can not be finished its processing and transportation, cause processing, installation, use and maintenance difficult.Master cylinder arrangement is satisfy slide block descending fast, selects single prefill valve structure for use, and the prefill valve structure is big, and is highly high.Outer slide does not have anti-drop device in existing, can not realize the purpose that slide block is anti-fall.This technological deficiency has influenced the operate as normal and the safe handling of large-scale double-action thick plate stretching hydraulic machine.
Summary of the invention
The present invention provides a kind of large-scale double-action thick plate stretching hydraulic machine for solving the technical problem that exists in the known technology.
Hydraulic press main frame of the present invention adopts outer slide reversely hung Yong kicker cylinder airframe structure in the large-scale combined framework, makes main frame have high rigidity; Hydraulic control system adopts proportion control, has accurate position, speed and force value; Adopting PLC and secondary meter to constitute digital control system in open type, is the developing direction of contemporary numerically controlled hydraulic press; Adopt exploitation of CAD/CAE/CAM integrated technology and manufacturing, product structure is scientific and reasonable; Adopt tele-control system to product quick diagnosis and service, satisfied the requirement of user the large product operating efficiency.Its main feature is:
(1) double linkage mechanism of large-scale double-action thick plate stretching hydraulic machine (blankholder slide and stretching slide block) can be suppressed respectively, can suppress simultaneously again, is applicable to two kinds of slab moulding process (thermoforming and cold forming).
(2) main frame adopts outer slide reversely hung Yong kicker cylinder structure in the group frame, and guide rail adopts rectangular configuration, the octahedral guiding, and stretching cylinder, flanging cylinder and slide block kicker cylinder all place in the main frame upper beam, and plunger rod is connected with outer slide with inner slide respectively with piston rod.Inner slide is a circular configuration, and outer slide is the structure of the outer mode of interior circle, and master cylinder adopts two prefill valve structures, has both satisfied the requirement of large press high speed, can reduce the whole height of press simultaneously again.
(3) this machine adopts the fast automatic mould changing device of super large stroke and the automatic clamping device of hydraulic oil cylinder driving, and repeatable accuracy is 0.05mm, is convenient to travelling table more mold exchange and lifting workpiece use.
(4) this machine slide block can stop in extreme position safety, is provided with the slide block anti-drop device, and when machine suspended use, slide block is fixed by hydraulic lock in the limes superiors position, and was safe and reliable.
(5) technological action of this machine is divided into adjustment, manual, semi-automatic and automatic working method, can realize two moving and two kinds of drawing process modes of single action when semi-automatic and automatic, but the pressing speed stepless time adjustment, and this machine is provided with automatic warnings and control device such as fluid heating and cooling.
(6) technological action of this machine is by the digital control system in open type that PLC and secondary meter constituted, and realizes that into numerical control device compacting goes digital control into press power with going by pressure sensor, by public communication networks product carried out remote diagnosis and control.
Employing new digital formula displacement transducer---magnetic grid and NC control system are as hydraulic press high reliability high-precision digital Position Control stroke digital control system.Can obtain the measurement result of resolving accuracy up to 1um and high repeatable accuracy.Replace that hydraulic press now adopts by structures such as mechanical transmission mechanism and circle grating form between control type stroke digital control system, there is error in the control accuracy underneath drive mechanism that is caused, after the outage of non-absolute value circle grating, energising must recover technical barriers such as zero-bit, satisfies the high control accuracy requirement of large-scale double-action thick plate stretching hydraulic machine.
The technical scheme that hydraulic press of the present invention is taked is:
