Abstract
The invention discloses a method for assembling and welding curved-surface sector-segment frames, which relates to a method for welding complex frames. By adopting positioning blocks and special process modules, a plurality of working-equipment matching surfaces and bearing blocks of upstanding-plate welding components are positioned, assembled and fixed respectively. The method has the advantages of raising work speed, saving 17 hours of assembly, reducing work intensity, improving machining quality and reducing rework rate from 40 percent to 5 percent.
Description
Technical field
The present invention relates to a kind of welding method of COMPLEX FRAME, the method for particularly a kind of curved surface sector-segment frames dress weldering.
Background technology
Curved surface sector-segment frames applying working condition is more abominable, is consumable accessory, and output is big.Bearing block quantity on the curved surface sector-segment frames is more, and not at grade, the machined required precision is high again, and as weldment, dress weldering difficulty is bigger.Existing metallurgical equipment manufacturer all adopts draws a ground line-transect, to the tapered bearing saddle by size its one by one the method for bed hedgehopping assemble, workload is big, product quality and production efficiency are all not high.
Summary of the invention
Technical problem to be solved by this invention provides the method for a kind of curved surface sector-segment frames dress weldering, can reduce the welding installation time, improves the product percent of pass of assembling.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the method for a kind of curved surface sector-segment frames dress weldering may further comprise the steps:
1) on the steel platform, draws the ground line-transect earlier,, riser, bearing block and the welding of pipe assembly are obtained the riser weld assembly by the locating piece location;
2) two of technical modules of process and assemble, and according to technological requirement reconditioning frock mating surface;
3) on the steel platform, two technical modules are located by the ground line-transect, guarantee that size is accurate;
4) each riser weld assembly is located assembling and fixing by bearing block and cooperating of frock mating surface, with side plate welding combination, obtain the curved surface sector-segment frames again.
Described technical module thickness is 5mm-20mm.
Described technical module processing method is for adopting the numerical control cutting machine cutting.
The method of a kind of curved surface sector-segment frames dress provided by the present invention weldering, by adopting locating piece and special technical module, the method that makes the bearing block of a plurality of frock mating surfaces on it and each riser weld assembly position, assemble and fix has following beneficial effect:
1, improves operating rate, will spend 32 hours, only need spend 15 hours after the assembling of adopting process module with a pre-installed table frame assembler;
2, reduce working strength, the size on the x of adjusting pad bearing block, y, three directions of z repeatedly when assembling in the past, labor strength is big.Utilizing locating piece the location to be installed easily, utilize two technical modules that each riser weld assembly is installed, very easy during operation, labour intensity reduces greatly;
3, improve crudy, bearing block is more and not in one plane, each bearing block processing capacity is also complicated, is forbidden to reprocess and dimensional discrepancy reaches 40% because of the bearing block dress with preceding, and only below 5%, allowance is more even for existing disqualification rate;
4, technical module adopts numerical control cutting machine to carry out cutting forming on the steel plate of 15mm, can guarantee machining accuracy and process time that the processing intensity of the reconditioning frock mating surface in later stage is also less.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.

The specific embodiment
The method of a kind of curved surface sector-segment frames dress weldering may further comprise the steps:
1) as among Fig. 2, on the steel platform, draw the ground line-transect earlier, by locating piece 4 location, riser 3, bearing block 2 and 5 welding of pipe assembly are obtained as the riser weld assembly among Fig. 3, locating piece 4 includes reference block, is used for determining the reference for assembling of workpiece;
2) as among Fig. 4, adopt numerical control cutting machine on the thick steel plate of 15mm process and assemble with 6 two of technical modules, and according to technological requirement reconditioning frock mating surface 7, even the locus and the angle of inclination of the bearing block after the locus of frock mating surface 7 and angle of inclination and the six riser weld assembly Rotate 180s ° on it are consistent;
3) on the steel platform, two technical modules 6 are located by the ground line-transect, guarantee that size is accurate;
4) as among Fig. 5, Fig. 6, each riser weld assembly is located assembling and fixing by bearing block 2 and cooperating of frock mating surface 7, be assembled into weldment and put and weld, guaranteed the location dimension of X, the Y of totally ten eight bearing blocks, three directions of Z like this, guaranteed the postwelding allowance of bearing block, with side plate 1 welding combination, obtained again as the curved surface sector-segment frames among Fig. 1.
