It is a kind of for the orthopedic straightening method of cradle cylinder body circularity that the present invention also provides, and this straightening method comprises following steps:
As shown in Figure 6 and Figure 7, slightly rectify the station layout and comprise following steps:
Step 1.1, measurement and mark cylinder internal diameter;
Measure the internal diameter of 8 equally divided positions in A, B, three cross sections of C in the cylindrical shell, be marked near the measurement point;
Described A cross section is positioned at the delivery port upper end, and described B cross section is positioned at the delivery port lower end, and described C cross section is positioned at the cylindrical shell lower end;
Step 1.2, at the peripheral mounting bracket of cylindrical shell and dial gauge;
Four midline positions in the cylindrical shell outside, 4 place's supports (or block of wood) are installed, are being taken personnel's observation platform (dial gauge is used on the observation support), the position in corresponding A, B, three cross sections of C on each support near the support, a dial gauge is installed respectively, controlling dimension when being used for rectifying type;
The stroke of described dial gauge is 80mm;
Step 1.3, shape righting tool 1 is installed to inner barrel;
Lifting shape righting tool 1 is held on the cushion block in the cylindrical shell to inner barrel;
Because cylindrical shell can't be out of shape greater than flange is arranged at blue place, the up and down linear variation of deflection of cylindrical shell is so the setting height(from bottom) of shape righting tool 1 is than the slightly high 50 ~ 100mm of delivery port axis;
The delivery port zone of 101 pairs of cylindrical shells of use hydraulic jack is carried out alternately orthopedic, until the diameter in cylindrical shell A cross section is poor less than 15mm;
Because B, C cross section can change with the A changes of section, always and diameter poor poor less than the A diameter of section, so need not to judge B, C cross section;
Use hydraulic jack 101 to push up to the cylindrical shell plastic deformation, judge whether the one-sided distortion of cylindrical shell accumulative total surpasses 3mm, if, then remeasure cylinder internal diameter (internal diameters of 8 equally divided positions in A, B, three cross sections of C), contrast with orthopedic measurement data front or that last time is orthopedic, confirm by the vary in diameter that contrast draws whether vary in diameter conforms to the dial gauge reading, and seek deformation tendency by vary in diameter;
Change in the thick registration that not only will monitor constantly each dial gauge of cylinder body outer wall in the process of rectifying, also need simultaneously to monitor constantly the exerting oneself of hydraulic pump of hydraulic jack, generation is only controlled deflection and ignore the strong accident of the stressed excessive mistake that causes in case the regional area strain is different with other zones with stressed relation;
Be diligent in analyzing the inner diameter measurement data, find out barrel distortion trend, if the deforming trend rhombus (as shown in Figure 8) of cylindrical shell, need not to install the square supporting member 103 in both sides when then orthopedic, if the deforming trend of cylindrical shell square (as shown in Figure 9), when then orthopedic the square supporting member 103 in both sides need to be installed, and adjust the distance that ejects of each square supporting member 103 by actual conditions;
Step 3, use vertical lathe are measured the cylindrical shell cylindricity;
Step 4, the smart station of rectifying are arranged;
As shown in figure 10, the smart all processes of rectifying all carries out at vertical lathe, bulk deformation trend that can the most effective grasp cylindrical shell;
Need to proofread and correct smoothing on the cylindrical shell behind the vertical lathe, this moment is because shell flange end rigidity better is out of shape minimum, can smooth with flange lower plane and symmetrical correction of flange excircle, concrete grammar in 0 ° in flange excircle sustained height cross section, 90 °, 180 °, 270 ° 4 angles respectively seek a point, play table and measure the cylindrical shell drift condition, use subsequently the claw on the lathe floral disc to adjust cylindrical shell until tubular axis and lathe floral disc center superposition; Equally, agree respectively to seek a point 0 °, 90 °, 180 °, 270 ° 4 angles on the diameter in the flange lower surface, play table and measure cylindrical shell inclination situation, adjust tubular axis until vertical with the lathe floral disc (the method common vertical lathe operative employee all know) by jack;
Step 5, smart rectifying;
The delivery port zone of 101 pairs of cylindrical shells of use hydraulic jack is carried out alternately orthopedic, until the cylindricity of cylindrical shell is less than or equal to 6.5mm;
The smart method of rectifying is with thick strong identical, but its amount of ejecting need to be smaller than slightly rectifying, in case excessively strong;
Every top is once or by behind the actual conditions top two to three times, measure the cylindricity in cylinder body outer wall A, B, C three cross sections with vertical lathe, grasp at any time the cylindricity data, constantly adjust the orthopedic amount of ejecting by these data, discovery has local deformation overproof, the small circular top then is installed part rectification (as shown in figure 11) is carried out in non-delivery port zone, guarantee that orthopedic general trend is for circular;
Two delivery ports replace orthopedic alternately opportunity so that the cylindricity data results of measuring is as the criterion, and are when both sides radius accumulative total deflection is identical, alternately orthopedic;
When one side delivery port was rectified type, the opposite side delivery port also can deform because of stressed, but this distortion is less; Because cylindrical shell material yield strength is not identical everywhere, so (be made as when a) rectifying type, the deflection of opposite side (being made as b) in this process is when rectifying type to opposite side delivery port (b), and the deflection that this side (b) occurs is different to a side delivery port; For example 90 ° of delivery ports are rectified type, make this side radial deformation 4mm, and 270 ° of side radial deformation 2mm; And when changing 270 ° of strong types, during 270 ° of side radial deformation 3mm, 90 ° of side radial deformation 1mm; In this case, both sides radius accumulative total deflection is identical, just should consider that at this moment side change rectifys type;
Step 6, installation hold round ring frock 2, and adjust the cylindricity of cylindrical shells to 4mm with holding round ring 201;
Install respectively three layers of A, B, C and to hold round ring 201, with the top bolt 2011 final cylindricities of cylindrical shells of adjusting to 4mm;
Step 7, size stabilization heat treatment.
After cylindrical shell done size stabilization heat treatment, the cylindrical shell size finalized the design almost.Although with the to some extent resilience of circularity that holds round the ring adjustment, still satisfy 5.08 cylindricity requirement.
Because hanging basket upper shell distortion former is because occur angular deformation during the delivery port welding, and showing as delivery port axis place internal diameter dwindles, and axis becomes the internal diameter in 90 ° of orientation bigger than normal therewith, and whole cylindrical shell becomes rule oval, so orthopedic mainly for the delivery port zone.
Because need to adjust fulcrum orientation and the fulcrum amount of ejecting according to deformation tendency when orthopedic, thus the necessary easy disassembly of the bracing or strutting arrangement that contacts with barrel around the shape righting tool, and the amount of ejecting has certain adjusting leeway.
The hydraulic jack of shape righting tool must have enough exerting oneself, and satisfies when orthopedic and brings the stress that exceeds the cylinder material yield strength to cylindrical shell, makes it plastic deformation.
The each several part of orthopedic appliance is all installed independently hanger, the needs when satisfying station layout and frock self installation.
