Description
Technical field
This utility model belongs to large hydraulic press technical field, particularly to a kind of large hydraulic press dimension compensation device.
Background technology
In free forging press, along with hydraulic pressure and the development of control technology, its size Control precision is greatly improved, typically
For ± 1mm, for the ultra-large type press of more than ten thousand tons, its size Control precision is up to ± 2mm, and automatic control level is higher.
But for large press, when forging, size Control is had an impact by the deformation of its frame stressing, and press tonnage is the biggest, and framework is the most just
The biggest, its stress deformation is the biggest, and forging actual size ratio is sized big, and for the press below 5000 tons, its framework becomes
Shape is less, generally 1～2mm, less on the impact of actual forging's block dimension；But for more than 5000 tons press, particularly ten thousand tons
Above press, frame deformation maximum also has 3～8mm, the most obvious on the impact of actual forging's block dimension.For big swaged forging
Part, surveys size during high temperature forging and is not easy very much, the size Control of press can only be relied on to complete actual forging, framework
Deformation often make actual forging size ratio be sized big, so make the utilization rate of forging material reduce.In freedom
In forging process, during owing to forging each time, according to differences such as forging material, temperature, drafts, required forging force is all each time
Different, it is impossible to the simple method using fixed value compensation carries out size revision.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of large hydraulic press size
Compensation device so that forging actual size be sized essentially identical, meet forging dimensional accuracy actual requirement.
In order to achieve the above object, this utility model adopts the technical scheme that:
A kind of large hydraulic press dimension compensation device, including the displacement sensing being fixed on underbeam 10 by fixed support 9
Device 8, the slide block on displacement transducer 8 is connected by the lower end of bearing pin 7 and fixing bar 4, and fixing bar 4 upper end is by upper fixed block 3
Connection fixing with upper beam 1, is fastened by stop nut 2 between upper fixed block 3 and fixing bar 4；
The signal output of displacement transducer 8 and the input of electric control system 11 connect, the output of electric control system 11
Input with hydraulic control system 12 connects, and when forging measured in real time by displacement transducer 8, the displacement between upper beam 1 and underbeam 10 becomes
Change, pass to electric control system 11, revised by size, electric control system 11 control hydraulic control system 12 and forge
Make.
It is connected on column 13 by more than one guide support block 5 in the middle part of described fixing bar 4.
Described fixing bar 4 and guide support block 5 are cylindrical slide-and-guide.
It is spaced 1.5 meters between described guide support block 5.
The beneficial effects of the utility model are: record upper beam 1 by displacement transducer 8 and the direct displacement of underbeam 10 becomes
Changing, the realtime deformation of framework is passed to electric control system 11 by displacement transducer 8 to carry out forging size revision in real time, controls
Hydraulic system 12 completes the forging to forging, it is achieved forges actual size and is sized within actual control accuracy, improves
The dimensional accuracy of forging, reduces the solid forging time, thus improves production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
See figures.1.and.2, a kind of large hydraulic press dimension compensation device, it is fixed on underbeam 10 including by fixed support 9
On displacement transducer 8, the slide block on displacement transducer 8 is connected by the lower end of bearing pin 7 and fixing bar 4, and fixing bar 4 upper end leads to
Cross fixed block 3 and the fixing connection of upper beam 1, fastened, at large hydraulic by stop nut 2 between upper fixed block 3 and fixing bar 4
During machine forging, the relative displacement of upper beam 1 and underbeam 10 produces change, records upper beam 1 by displacement transducer 8 and underbeam 10 is direct
Change in displacement, i.e. the deflection of framework is measured in real time by displacement transducer 8；The signal output of displacement transducer 8 is with electric
The input of control system 11 connects, and the output of electric control system 11 and the input of hydraulic control system 12 connect, by hydraulic pressure control
System 12 processed has controlled the forging to forging, records upper beam 1 by displacement transducer 8 and underbeam 10 is real-time in forging process
Deflection passes to electric control system 11 to carry out forging size revision in real time, controls hydraulic system 12 and completes the forging to forging
Make, it is achieved forge actual size and be sized within actual control accuracy.
It is connected on column 13 by more than one guide support block 5 in the middle part of described fixing bar 4.
Described fixing bar 4 and guide support block 5 are cylindrical slide-and-guide, can effectively prevent fixing bar 4 from self quivering
Dynamic, upper beam 1 and the change in displacement of underbeam 10 can be accurately reflected.
It is spaced 1.5 meters between described guide support block 5, eliminates fixing bar 4 in forging process because self vibration causes
Offset deviation.
Operation principle of the present utility model is:
When large hydraulic press forges, forging 6 stress deformation, its counteracting force is made up of upper beam 1, underbeam 10 and column 13
Framework bear so that column 13 extends, i.e. upper beam 1 and underbeam 10 relative displacement produce change；Can by displacement transducer 8
Recorded in real time by displacement transducer 8 recording the deflection of upper beam 1 and underbeam 10 direct change in displacement, i.e. framework；Displacement
The realtime deformation of framework is passed to electric control system 11 by sensor 8 to carry out forging size revision in real time, controls hydraulic pressure system
System 12 completes the forging to forging, it is achieved forges actual size and is sized within actual control accuracy, improves forging
Dimensional accuracy, reduces the solid forging time, thus improves production efficiency.
