Example 1
The specific implementation scheme of the furnace mouth reinforcing ring cutting tool is further described by combining the attached drawings, and the specific technical scheme of the furnace mouth reinforcing ring cutting tool is as follows: the furnace mouth reinforcing ring has a bottom plate 1, the diameter phi 1800 is determined according to the external contour projection size phi 1400 of a specific furnace mouth reinforcing ring blank, and the diameter difference is 400mm, so that the phi 1800 size can be flexibly adjusted according to different furnace mouth reinforcing ring requirements. The use state is that the support plate 2 and the auxiliary plate 1 are horizontally placed and welded on the support plate.
The height 600mm of the supporting plate 2 is determined according to the relative height difference of high and low points when the furnace mouth reinforcing ring is placed in a certain inclined angle, the 600mm height ensures that the lowest point of a furnace mouth reinforcing ring blank leaves the bottom plate by more than 50mm, and therefore the 600 size can be flexibly adjusted according to the requirements of different furnace mouth reinforcing rings. The curve of the top surface of the supporting plate 2 is obtained by connecting curve lofting transplantation of height on the inner arc surface of the furnace mouth reinforcing ring, and the length 1300 dimension is obtained according to the smaller 100mm of the outer circle dimension phi 1400 of the furnace mouth reinforcing ring, so the 1300 dimension can be flexibly adjusted according to different furnace mouth reinforcing rings.
The height 591.9 of the auxiliary plate 1 is determined according to the relative height difference of high and low points when the furnace mouth reinforcing ring is placed in an inclined way at a certain angle, the 591.9mm height ensures that the lowest point of a furnace mouth reinforcing ring blank is more than 50mm away from the bottom plate, so the 591.9 size is flexibly adjusted according to different furnace mouth reinforcing ring requirements. It is characterized in that the supporting plate 2 is matched to support the furnace mouth reinforcing ring together, and the horizontal distance between the auxiliary plate 1 and the supporting plate 2 is 500 mm. The 500mm is obtained by taking the middle value according to the size of the inner circle and the outer circle of the furnace mouth reinforcing ring and then taking the distance between the furnace mouth reinforcing ring and the supporting plate 2 into consideration. The length of the auxiliary plate 1 is the chord length of the phi 1300 circle on the bottom plate after the distance between the auxiliary plate and the supporting plate 2 is determined. The size of the upper arc is obtained by lofting and transplanting the inner arc curve of the reinforcing ring of the furnace mouth at the corresponding position.
And after the furnace mouth reinforcing ring tool assembled according to the figure 1 is welded. The furnace mouth reinforcing ring can be buckled on a tool, and after the furnace mouth reinforcing ring is installed in place, the auxiliary plate 1 of the supporting plate 2 is ideally in close contact with the furnace shell reinforcing plate without obvious gaps. Meanwhile, the vertical projection distance of the furnace mouth reinforcing ring from the edge of the bottom plate is uniform and 200 mm. Under the state, macro program cutting of the numerical control cutting machine can be carried out.
