The present embodiment is at the enterprising one-step optimization in the basis of any of the above-described embodiment, shape measure and the method for control in a kind of heavy shell ring operation of rolling, as Figure 1-Figure 8, comprises the following steps:
Step 1: infrared ray displacement transducer 3 is set in mounting system, described infrared ray displacement transducer 3 is positioned at head end or the tail end of heavy shell ring 5 to be processed, 2 infrared ray displacement transducers 3 and a magnetostrictive displacement sensor is utilized to form 3 measuring points, and near the approximate external diameter being distributed on heavy shell ring head end or tail end of 3 measuring points, and the measurement ray that infrared ray displacement transducer 3 sends is 45 ° with horizontal direction.
Step 2: using the center of rotation of core roller 9 as zero, demarcates the coordinate points of the head end of heavy shell ring 5 to be processed or the measuring point of tail end, the coordinate points of infrared ray displacement transducer 3 and magnetostrictive displacement sensor；And in data handling system, the analysis coordinate system of heavy shell ring 5 to be processed is set up according to determined measuring point and coordinate points；Described analysis coordinate system includes: the coordinate points A of infrared ray displacement transducer 3, the coordinate points B of infrared ray displacement transducer 3, the coordinate points D of magnetostrictive displacement sensor, the outer surface measuring point E of heavy shell ring 5 head end, the outer surface measuring point F of heavy shell ring 5 head end, the measuring point D` of head end after heavy shell ring 5 rolling processing, head end measuring point F` after heavy shell ring 5 rolling processing, the measuring point E` of head end after heavy shell ring 5 rolling processing.
When carrying out tail end and measuring, E, F, D`, F`, E` refer to respectively: the outer surface measuring point E of heavy shell ring 5 tail end, the outer surface measuring point F of heavy shell ring 5 tail end, the measuring point D` of heavy shell ring 5 rolling processing rearward end, heavy shell ring 5 rolling processing rearward end measuring point F`, the measuring point E` of heavy shell ring 5 rolling processing rearward end
Step 4: using core roller 9 center of rotation as zero, demarcates magnetostrictive displacement sensor and infrared displacement sensor 3, it is thus achieved that coordinate points A(X0`,Y0`), coordinate points B (X0,Y0) and coordinate points D (X3,Y3) coordinate；
Step 5: measure coordinate points B (X with infrared ray displacement transducer 30,Y0) put the outer surface measuring point E (X arriving heavy shell ring 5 head end1,Y1) distance L between point1And coordinate points A(X0`,Y0`) to the outer surface measuring point F (X of heavy shell ring 5 head end2,Y2) distance L between point2；
Step 6: by coordinate points A(X0`,Y0`), coordinate points B (X0,Y0) coordinate, distance L1With distance L2, by geometrical relationship X1=X0-L1* Cos45 °, Y1=Y0-L1* Sin45 °, X2=X0`+L2* Cos45 °, Y1=Y0`-L2* Sin45 °, can calculate and obtain E (X1,Y1) put and F (X2,Y2) point coordinates；
Step 7: according to coordinate points D (X3,Y3), measuring point E (X1,Y1) and measuring point F (X2,Y2) coordinate, determine round principle in conjunction with 3, derive the outside dimension D1 of heavy shell ring 5 head end；
Step 8: by the magnetostrictive displacement sensor on hydraulic cylinder 8, records heavy shell ring 5 head end gap values between rollers H1；
Step 9: deduct 2 times of head end gap values between rollers H1 according to the heavy shell ring 5 head end outside dimension D1 obtained, can calculate and obtain heavy shell ring 5 head end internal diameter size d1；
Step 10: in like manner, repeating step 4-9 and carry out the measurement of heavy shell ring 5 tail end, when carrying out tail end and measuring, the outside dimension D1 of head end becomes the outside dimension D2 of tail end, head end internal diameter size d1 becomes the internal diameter size d2 of tail end, and head end gap values between rollers H1 becomes tail end gap values between rollers H2；
Step 11: along with constantly carrying out of the operation of rolling, heavy shell ring 5 size can change (inside and outside footpath constantly increases, and wall thickness is constantly thinning), as long as at this moment measuring B (X with infrared ray displacement transducer 30,Y0) arrive heavy shell ring 5 outer surface E` (X1`,Y1Distance L` between `) and measure the stroke of hydraulic cylinder 8 with magnetostrictive displacement sensor and obtain D` (X3`,Y3`) the coordinate put, it is possible to repeating the calculating process of step 6 and step 7, counterweight type tube saves 5 shapes and carries out real-time measurement.
Step 12: after step 11, will appear from following situation and carries out regulating accordingly:
A.1, as shown in Figure 4, when recording, heavy shell ring 5 head end internal diameter size d1 is consistent with tail end internal diameter size d2, and head end outside dimension D1 more than trailing end outer diameter dimension D 2 time, heavy shell ring 5 shape is outer cone shape, the heavy type axial cut away view of shell ring 5.Now, operator in roll control room strengthens hydraulic cylinder 8 by data handling system, and in the amount of pressing of heavy shell ring 5 head end, (amount of pressing obtains according to the tapering calculating of inner cone, this calculation is prior art, is not detailed at this), thus reducing the outside dimension of heavy shell ring 5 head end.
A.2 as it is shown in figure 5, consistent with trailing end outer diameter dimension D 2 when record heavy shell ring 5 head end outside dimension D1, and head end internal diameter size d1 less than tail end internal diameter size d2 time, heavy type shell ring 5 shape is inner cone shape.Now, operator in roll control room strengthens hydraulic cylinder 8 by data handling system, and in the amount of pressing of heavy shell ring 5 head end, (amount of pressing obtains according to the tapering calculating of inner cone, this calculation is prior art, is not detailed at this), thus increasing the internal diameter size of heavy shell ring 5 head end.
A.3, as shown in Figure 6, when recording heavy shell ring 5 head end internal diameter size d1 more than tail end internal diameter size d2, when head end outside dimension D1 is also greater than trailing end outer diameter dimension D 2 simultaneously, heavy shell ring 5 shape is horn-like (inside and outside taper direction is identical).Now, operator in roll control room controls hydraulic cylinder 8 by data handling system, hydraulic cylinder 8 drives driving pressure top roll 7 to adopt the rolling mode tilted to roll, when carrying out tilt rolling, angle of inclination can calculate according to the tapering of interior outer cone, and these computational methods are prior art, are not detailed at this.
A.4 as it is shown in fig. 7, when record heavy shell ring 5 head end internal diameter size d1 less than tail end internal diameter size d2, and head end outside dimension D1 more than trailing end outer diameter dimension D 2 time, heavy shell ring 5 shape is horn-like (inside and outside taper direction is contrary).Now, operator in roll control room strengthens hydraulic cylinder 8 by data handling system and obtains in the tapering calculating measured on piezometric according to inner cone that presses of heavy shell ring 5 head end, this calculation is prior art, it is not detailed at this), thus reducing the wall thickness of heavy shell ring 5 head end, by the unnecessary extruding metal outside to heavy type shell ring 5.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction, every above example is made according to the technical spirit of the present invention any simple modification, equivalent variations, each fall within protection scope of the present invention.
