Abstract

The invention provides a blanking and welding method for a generator stator ring plate which has a local gap or of which the inner hole is relatively large in size. When in blanking, the method of changing the structure and size and increasing the rigidity to resist the effect of the thermal stress of cutting flame as well as controlling the deformation degree is carried out to ensure the blanking precision; the discontinuous cutting method is carried out to ensure that the generator stator ring plate can be kept in rigidity as requirement during welding; the materials of an auxiliary part can be cut after welding, and therefore, the deformation of the generator stator ring plate, an outer coating of a base and the corresponding part during welding can be controlled.

Description

The blanking of generator unit stator ring flat-plate and welding method
Technical field: the blanking and the welding method that the present invention relates to a kind of generator unit stator ring flat-plate.
Background technology: for reducing stator draft loss, improve generator efficiency, solve generator unit stator transportation bottleneck problem, project organization was less more in the past for the outside dimension of the electricity generator stator stand of new construction, some structure members embed ring flat-plate, define the generator unit stator ring flat-plate with local breach, the mother metal radial width undersize 200mm of some gap portions, make thisly there is local radial insufficient rigidity problem with local breach generator unit stator ring flat-plate, employing conventional art carries out blanking and welding can cause following point: be first that the mother metal radial width undersize of gap portions is to resist the effect that essence cuts the thermal stress of process cutting flame, blanking is caused to be out of shape excessive and instructions for use cannot be met, the not enough problem of radial rigidity of welding process gap portions also can cause welding deformation excessive, electricity generator stator stand is out of shape serious, is difficult to meet instructions for use, also there are the problems referred to above in the larger-size ring flat-plate of some diameter of bores.
Summary of the invention: the blanking and the welding method that the invention provides a kind of generator unit stator ring flat-plate, for with local breach or the larger-size generator unit stator ring flat-plate of diameter of bore, during blanking, change structure and size increase the method guarantee cutting stock precision of rigidity, adopt interrupted cutting method, keep generator unit stator ring flat-plate in welding process, maintain required rigidity, be convenient to again the slave part material having welded rear excision redundancy.
Technical scheme of the present invention is: a kind of blanking of generator unit stator ring flat-plate and welding method, it is characterized in that: during blanking, the diameter dimension of the blanking endoporus of generator unit stator ring flat-plate is reduced 400mm-500mm by nominal size, essence cuts off material, along nominal size diametrically interrupted Cutting Length be the gap of 300mm-350mm, spacer length 50mm-80mm; After welding with support crust and corresponding component, along nominal size diameter cutting spacer, slave part is departed from.
Technique effect: owing to the diameter dimension of the blanking endoporus of generator unit stator ring flat-plate being reduced 400mm-500mm by nominal size during blanking, ring flat-plate is made to have enough radial width sizes, there is the effect that enough rigidity and intensity resist the thermal stress of cutting flame, controlling distortion degree, can meet the requirement that essence cuts off material size Control; Along nominal size diametrically interrupted Cutting Length be the gap of 300mm-350mm, redundance material is formed subring that one has enough rigidity, spacer makes subring be formed with effective ring flat-plate to be connected, length is that the size of 50mm-80mm had both met the coupling stiffness requirement with subring, is convenient to again the convenience of having welded rear removing subring; Under the restraining function of subring, the welding process of generator unit stator ring flat-plate and support crust and corresponding component is out of shape and is controlled.
Accompanying drawing illustrates:
Fig. 1 is that the present invention is applied in a kind of generator unit stator ring flat-plate blanking schematic diagram with local breach.
Fig. 2 is that the present invention is applied in a kind of rear schematic diagram of generator unit stator ring flat-plate welding with local breach.
Fig. 3 is that the present invention is applied in a kind of diameter of bore larger-size generator unit stator ring flat-plate blanking schematic diagram.
Fig. 4 is that the present invention is applied in the rear schematic diagram of a kind of diameter of bore larger-size generator unit stator ring flat-plate welding.
Detailed description of the invention:
As shown in Figure 1, that the present invention is at a kind of baiting method typically with the generator unit stator ring flat-plate of local breach, during blanking, the diameter dimension of the blanking endoporus 2 of generator unit stator ring flat-plate 1 is reduced 400mm-500mm by nominal size, essence cuts off material, on nominal size diameter 3, interrupted Cutting Length is the gap 4 of 300mm-350mm, spacer 5 length 50mm-80mm;
As shown in Figure 2, after welding with support crust 6 and breach corresponding component 7, cut spacer 5 along nominal size diameter 3, slave part 8 is departed from;
As shown in Figure 3, the present invention in the blanking of the larger-size ring flat-plate of a kind of typical diameter of bore and welding method, during blanking, the diameter dimension of the blanking endoporus 2 of generator unit stator local breach ring flat-plate 1 is reduced 400mm-500mm by nominal size, essence cuts off material, on nominal size diameter 3, interrupted Cutting Length is the gap 4 of 300mm-350mm, spacer 5 length 50mm-80mm;
As shown in Figure 4, after welding with support crust 6, cut spacer 5 along nominal size diameter 3, slave part 8 is departed from;
Owing to the diameter dimension of the blanking endoporus of generator unit stator local breach ring flat-plate being reduced 400mm-500mm by nominal size during blanking, the radial width size of ring flat-plate is made to have enough rigidity and intensity, resist the thermal stress of gas flame cuttiug, the requirement of essence being cut off to material size Control can be met; Along nominal size diametrically interrupted Cutting Length be the gap of 300mm-350mm, redundance material is formed subring that one has enough rigidity, spacer makes subring be formed with effective ring flat-plate to be connected, length is that namely the size of 50mm-80mm meets the coupling stiffness requirement with subring, is convenient to again the convenience of having welded rear removing subring; Under the restraining function of subring, the welding process of generator unit stator ring flat-plate and support crust and breach corresponding component is out of shape and is controlled.
