Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
As shown in Figures 1 to 4, be a kind of large scale melon skin arc base plate tool structure for processing schematic diagram described in the utility model.A kind of large scale melon skin arc base plate processing tool described in the utility model, comprise: two bottom girders 1, be fixedly installed bottom described bottom girder 1, the top of described bottom girder 1 is provided with support panel 11, needs the both sides of the melon skin plate 2 of processing to be placed on the described support panel 11 of two described bottom girders 1 respectively; The described support panel 11 of two described bottom girders 1 is respectively provided with a lapping plate 3, described lapping plate 3 is fixedly installed relative to described bottom girder 1, and the sidepiece of described lapping plate 3 is used for and needs the both sides of the melon skin plate 2 of processing to weld; Some groups of portal frames, often organize described portal frame and include two installation vertical beams 71 vertically arranged, the bottom of two described installation vertical beams 71 is fixedly installed on the described support panel 11 of two described bottom girders 1 respectively, is provided with counter-force crossbeam 72 between the top of two described installation vertical beams 71; Often organize the described counter-force crossbeam 72 of described portal frame and need to be provided with hydraulic jack 8 between the symmetrical center line of the melon skin plate 2 processed, bottom described hydraulic jack 8 and need to be provided with arc punch 9 between the melon skin plate 2 processed, described arc punch 9 top contacts with described hydraulic jack 8, be provided with the arc contact surface 91 of the melon skin plate 2 for contact need processing bottom described arc punch 9, the arc radius of described arc contact surface 91 is less than the predetermined arc of the melon skin plate 2 at contact position place.
Particularly, described arc punch 9 be strip and along need processing melon skin plate 2 symmetrical center line arrange.Preferably, the both sides of melon skin plate 2 of processing and the Welding Structure of the described support panel 11 of described bottom girder 1 and described lapping plate 3 is needed to comprise: the first welding line 4 between described support panel 11 end face and melon skin plate 2 bottom surface, and the welding line again 5 between described support panel 11 side and melon skin plate 2 bottom surface, and the last welding line 6 between described lapping plate 3 side and melon skin plate 2 side.
The processing step applied when above-mentioned a kind of large scale melon skin arc base plate processing tool is constructed to the melon skin plate in background technology is as follows:
Step one, carry out planar trapezoidal melon skin plate 2 cut blanking;
Step 2, the planar trapezoidal melon skin plate 2 after cutting to be lifted on bottom girder 1, and to adjust displacement centering;
Step 3, above the symmetrical center line Y of planar trapezoidal melon skin plate 2, be fixedly installed some hydraulic jack 8 relative to bottom girder 1, hydraulic jack 8 is provided with the arc punch 9 with arc contact surface 91 with the contact jaw of melon skin plate 2, applies downforce make the deformation of planar trapezoidal melon skin plate 2 have radian by the symmetrical center line Y place of hydraulic jack 8 pairs of planar trapezoidal melon skin plates 2; The arc radius of arc punch 9 should be slightly less than the predetermined arc of the melon skin plate 2 at contact position place, so that have certain resilience surplus after making melon skin plate 2 compressive deformation;
Step 4, on bottom girder 1, being fixedly installed lapping plate 3, breaking welded together by having melon skin plate 2 both sides of radian and bottom girder 1 and lapping plate 3;
Step 5, remove hydraulic jack 8, application carbon dioxide gas arc welding makes melon skin plate 2 both sides and bottom girder 1 and lapping plate 3 full weld.
Preferably, in described step 4, melon skin plate 2 both sides and bottom girder 1 and the disconnected method of weld of lapping plate 3 are: first break welded together by melon skin plate 2 liang of side bottoms and bottom girder 1, then by the top of melon skin plate 2 both sides and sidepiece and break welded together.Further optimally, in described step 5, the full weld structure of melon skin plate 2 both sides and bottom girder 1 and lapping plate 3 comprises the first welding line between bottom girder 1 end face and melon skin plate 2 bottom surface, and the welding line again between bottom girder 1 side and melon skin plate 2 bottom surface, and the last welding line between lapping plate 3 side and melon skin plate 2 side.
Particularly, to break weldering 30% at melon skin plate 2 liang of side bottoms, then weldering 50% of breaking in the side of melon skin plate 2 both sides and upper surface, last synchronous welding positive melon skin plate about 2 gap is to qualified weld bead height; After above-mentioned preferred technique can ensure hydraulic jack release, after resilience, radian value is ensured, and can prevent the welding of one side slit from causing distortion.
Owing to easily producing welding deformation when monolithic melon skin plate 2 is welded on bottom girder 1, and the stressed generation of the corresponding bottom girder in bottom two 1 is from melon skin plate 2 center line toward extrapolability, respectively at the deformation values of epimere, stage casing, end section formation+8 millimeters ,+6 millimeters ,+3 millimeters, produce the positive dimensional discrepancy of the whole circle of accumulation simultaneously.For this reason preferably, two groups of adjacent melon skin plates 2 carry out the operation of step 2 to step 4 simultaneously.Further preferably, symmetrical installation taked by the melon skin plate 2 of whole cone bottom surface.Thus reach all bottom girder 1 position deviation minimum of a values, and it is complementary to obtain positive and negative dimensional discrepancy.
Particularly, the melon skin plate 2 of trapezoidal upper base 2.7 meters by 5 groups of portal frames, 43 kilograms every meter track, hydraulic jack is exerted pressure, and top is recessed reaches radian value required in background technology after 390 millimeters, after release, stress recoils to 350 millimeters, after several times test respectively to upper base eject overflow 40 millimeters, 25 millimeters, middle part, go to the bottom 10 millimeters, reach melon skin plate 2 drawing requirement radian value after stress resilience.Particularly, as shown in Figure 4, the hydraulic coupling of top-down 5 hydraulic jack selects 32 tons, 50 tons, 100 tons, 32 tons and the 32 tons making being applicable to the melon skin plate of institute's preliminary dimension specification in background technology the most respectively.
Above content is in conjunction with specific embodiments to the detailed description that the utility model is done, and can not assert that the utility model is specifically implemented to be only limitted to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as the scope belonging to the utility model protection.
