Specific embodiment
1-4, a kind of 60MN frame hydraulic press single head oil electricity Hybrid Heating pre-tightening apparatus, including main frame and vertical referring to the drawings
Oily electricity Hybrid Heating pre-tightening apparatus, 6 pull bar upper ends are provided with the straight hole 1 that depth is deeper than the height of upper beam 2, can more meet vertical machine list
The actual heating pretension demand of head；Upper beam 2, column 3 and workbench 4 are installed with pull bar 6, and two ends are locked by the mechanical whorl of locknut 5；Pull bar
Heat exchange jacket 9 is inserted with 6 straight holes 1；In the injection heat exchange jacket 9 of industrial conduction oil 10；Heating rod 7 is using sectionally assembled and be furnished with
Temperature sensor, is suitable for the heating of different depth straight hole 1 and temperature value feedback control；Heating rod 7 is inserted directly into conduction oil 10；
Heating rod 7 is used to be threadedly coupled and adjust packing ring 8 and sealed with the end of pull bar 6；Heating rod 7 is connected with electric temperature control device 11.It is main
Machine pull bar single head straight hole 1 installs four groups of oil electricity Hybrid Heating pre-tightening apparatus altogether.11 independent control of electric temperature control device, four groups of oil electricity
Hybrid Heating pre-tightening apparatus, temperature control is independent of each other.
A kind of above-mentioned 60MN frame hydraulic press single head oil electricity Hybrid Heating pre-tightening apparatus, are in particular in following three ranks
Section：
A. industrial conduction oil warm-up phase：According to parameters such as design pretightning force, rod material elastic modelling quantity and linear expansion coefficients
The heat energy total amount that pull bar needs can be drawn, the factors such as heat loss are taken into full account, industrial heat conduction is drawn using thermodynamic analysis means
Oily theory heating-up temperature, industrial conduction oil preheating temperature is set by theoretical value.
B. heating pretension pull bar extends the stage：Such as Fig. 2, lasting heat is exported can allow pull bar to produce line bulging deformation amount,
Be can determine that using photoelectric sensor 14Value changes, the heat effect area outer round surface of pull bar 6 is detected through temperature detection window 12
Different temperatures measuring point temperature value size, take its temperature peak, carry out the heat analysis amendment of pull bar 6, industrial heat conduction is corrected again
The operating temperature of oil 10, until the deflection of pull bar 6 that complete design needs.
C. cool down and complete the stage：When the deflection of pull bar 6Meet design requirement, you can screw workbench lower section locknut 5,
Heating pretension is completed using principle of expanding with heat and contracting with cold to work.
Wherein, the A stages show as：
Step 1, design pull bar pretension coefficient is 1.2, and pull bar theoretical elongation can be calculated by Hooke's law,
The pull bar theoretical elongation for calculating；
Step 2, perfect condition is issued to pull bar elongation, the transformation temperature of whole pull bar；
Step 3, the energy value that whole pull bar thermal deformation needs；
In formula：- pretightning force,- pull bar length,- rod material elastic modelling quantity,- pull bar minimum cross-sectional area,-
Pull bar linear expansion coefficient,- pull bar quality,- rod material specific heat capacity,- heat loss；
Step 4, using heat analysis method, show that industrial conduction oil theory heating-up temperature is 320 DEG C or so, and pull bar temperature is surveyed
Point maximum temperature is at 180 DEG C or so；Theory heating duration is in 33h or so.
Wherein, B-stage shows as：
Step 1, checks that the temperature value and pull bar of a temperature detection window temperature measuring point are actual and becomes at regular intervals
Shape amount, record result as follows：It is right when temperature point maximum temperature is respectively 55 DEG C, 85 DEG C, 115 DEG C, 145 DEG C and 155 DEG C
AnswerIt is 1.3mm, 2.8m, 3.6mm, 4.4mm and 4.5mm to be worth, corresponding heating duration be respectively 6h, 14h, 28h, 48h and
72h。
Step 2, continuous heating, when pull bar temperature point temperature peak reaches 165 DEG C, industrial heat conduction oil temperature has reached
To 365 DEG C, the now deflection of pull bar5.1mm or so is basically stable at no longer to change.
Wherein, C-stage shows as：
Step 1,During for 5.1mm, heating pretension design requirement having been met, can having terminated to heat pretension, workbench has been locked at once
Lower section locknut.
Step 2, timeliness to room temperature can complete the pretension work of pull bar.
