8, can set the servo-cylinder amount of piston displacement, ring anglec of rotation tolerance.
The computer control system separate case is applied for a patent, during arbor press work, hot annular blank spare to be corrected is delivered to the below of haul dolly earlier through raceway, be transported to the center of leveling block after hooking by the gib head of haul dolly again, after being placed on this blank on each cushion block, the haul dolly breaks off relations and returns, and then treats the ellipse of correcting annular blank and corrects:
1, each servo-cylinder piston moves to the workbench center under less than the 1MPa situation at system pressure.
When 2, each servo-cylinder piston was run into annular blank spare external diameter, because system pressure is very little, each piston rod stopped to move, and the simultaneous computer display screen shows 6 mobile sizes, and calculates moving average.
3, given this mean value of computer, system pressure is increased to 16MPa, and six servo-cylinder pistons move to mean value synchronously, and annular blank spare is out of shape rapidly when 600 ° of C--800 ° of C, and the long axis of ellipse of annular blank spare is dwindled, and minor axis strengthens.
4, six servo-cylinders retreat synchronously, each carrying roller jack-up annular blank and rotate an angle after fall.
5, six servo-cylinder pistons move to mean value again synchronously under 16MPa pressure, correct again.
6, so after 4-5 time, six servo-cylinder pistons move to the workbench center under the 1MPa low-pressure and measure mean value for the second time, if mean value less than the permissible variation value, oval correction finishes, if, carrying out secondary high-pressure again greater than the permissible variation value, corrects mean value.
7, rectification finishes the annular blank spare outside dimension after the back computer is read rectification, measures maximum, minimum outer diameter size and maximum deflection difference value and record for the first time.
It is smooth then annular blank spare to be carried out warpage, and its course of work is:
1, each motor reducer drive screw, moving slider moves to each depress oil cylinder the top of annular blank spare external diameter.
2, each depress oil cylinder piston is when 16MPa pressure is depressed, and the annular blank spare of warpage is out of shape.
3, each depress oil cylinder piston rises.
4, angle of each carrying roller jack-up annular blank rotation falls.
5, each depress oil cylinder presses down once more annular blank spare is out of shape once more.
6, behind annular blank spare Rotate 180 °, the smooth end of warpage.
7, this computer-chronograph sense loop shape blank height dimension, and record.
Numerically controlled annular steel-piece ellipse warp thermal-state straightening device proposed by the invention, novel structure, safe and reliable, reduced the reservation allowance of annular blank spare, reduced waste product, the saving of work and time energy savings, the yield rate height has reduced cost.
