Description
Technical field
The invention belongs to large hydraulic press technical field, particularly to a kind of large hydraulic press size
Compensation system.
Background technology
In free forging press, along with hydraulic pressure and the development of control technology, its size Control essence
Degree is greatly improved, generally ± 1mm, for the ultra-large type press of more than ten thousand tons, and its size control
Precision processed is up to ± 2mm, and automatic control level is higher.But for large press, in forging
Time, size Control is had an impact by the deformation of its frame stressing, and press tonnage is the biggest, and framework is also more
Greatly, its stress deformation is the biggest, and forging actual size ratio is sized big, for 5000 tons
Following press, its frame deformation is less, generally 1～2mm, affects actual forging's block dimension
Less；But for more than 5000 tons press, the press of particularly more than ten thousand tons, framework becomes
Shape 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, can only rely on the size Control of press
Completing actual forging, the deformation of framework often makes actual forging size ratio be sized big,
The utilization rate so making forging material reduces.During flat-die forging, owing to forging each time
When making, according to differences such as forging material, temperature, drafts, required forging force is the most each time
With, 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, it is an object of the invention to provide a kind of large-scale
Hydraulic press dimension compensation system so that forging actual size be sized essentially identical, meet
Forging dimensional accuracy actual requirement.
In order to achieve the above object, the present invention adopts the technical scheme that:
A kind of large hydraulic press dimension compensation system, is fixed on underbeam including by fixed support 9
Displacement transducer 8 on 10, the slide block on displacement transducer 8 passes through bearing pin 7 and fixing bar 4
Lower end connect, fixing bar 4 upper end is by upper fixed block 3 and upper beam 1 is fixing connects, upper solid
Determine to be fastened by stop nut 2 between block 3 and fixing bar 4；
The signal output of displacement transducer 8 and the input of electric control system 11 connect, electrically
The output of control system 11 and the input of hydraulic control system 12 connect, and displacement transducer 8 is real
Time measure forging time upper beam 1 and underbeam 10 between change in displacement, pass to electrical control system
System 11, is revised by size, electric control system 11 controls hydraulic control system 12 and enter
Row forging.
It is connected to column by more than one guide support block 5 in the middle part of described fixing bar 4
On 13.
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 invention have the benefit that and record upper beam 1 and underbeam 10 by displacement transducer 8
Directly change in displacement, the realtime deformation of framework is passed to electrical control by displacement transducer 8
System 11 carries out forging size revision in real time, controls hydraulic system 12 and completes the forging to forging,
Realize forging actual size and be sized within actual control accuracy, improving the size of forging
Precision, reduces the solid forging time, thus improves production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Seeing figures.1.and.2, a kind of large hydraulic press dimension compensation system, including by fixing
Support 9 is fixed on the displacement transducer 8 on underbeam 10, and the slide block on displacement transducer 8 leads to
The lower end crossing bearing pin 7 and fixing bar 4 connects, and fixing bar 4 upper end is by upper fixed block 3 and upper
Beam 1 is fixing to be connected, and is fastened by stop nut 2 between upper fixed block 3 and fixing bar 4,
During large hydraulic press forging, the relative displacement of upper beam 1 and underbeam 10 produces change, by position
Displacement sensor 8 records upper beam 1 and the deflection of underbeam 10 direct change in displacement, i.e. framework
Measured in real time by displacement transducer 8；The signal output of displacement transducer 8 and electrical control system
The input of system 11 connects, the output of electric control system 11 and hydraulic control system 12 defeated
Enter to connect, hydraulic control system 12 controlled the forging to forging, in forging process
Record upper beam 1 by displacement transducer 8 and underbeam 10 realtime deformation passes to electrical control
System 11 carries out forging size revision in real time, controls hydraulic system 12 and completes the forging to forging,
Realize forging actual size and be sized within actual control accuracy.
It is connected to column by more than one guide support block 5 in the middle part of described fixing bar 4
On 13.
Described fixing bar 4 and guide support block 5 are cylindrical slide-and-guide, can be the most anti-
The most fixing bar 4 self vibration, can accurately reflect upper beam 1 and the change in displacement of underbeam 10.
It is spaced 1.5 meters between described guide support block 5, eliminates fixing bar 4 at forging process
Middle vibration because of self causes offset deviation.
The operation principle of the present invention is:
When large hydraulic press forges, forging 6 stress deformation, its counteracting force by upper beam 1,
The framework of underbeam 10 and column 13 composition bears so that column 13 extends, i.e. upper beam 1 He
The relative displacement of underbeam 10 produces change；Upper beam 1 He can be recorded by displacement transducer 8
The deflection of underbeam 10 direct change in displacement, i.e. framework is surveyed in real time by displacement transducer 8
?；It is real-time that the realtime deformation of framework is passed to electric control system 11 by displacement transducer 8
Carry out forging size revision, control hydraulic system 12 and complete the forging to forging, it is achieved forging
Actual size and be sized within actual control accuracy, the dimensional accuracy of raising forging, subtract
Few solid forging time, thus improve production efficiency.
