Background technology
Pressure vessel tube sheet forging, is relatively large in diameter and thinner thickness.Under normal circumstances, when using original common rotary table spinning forging diameter tube sheet type heavy forged piece in the range of φ 5500 ~ 7000mm, common forging rotary table work top is isometrical with rotating part, design maximum specification is 5500mm, weight 180 ~ 200t, designs 7000mm specification rotary table weight about 300 ~ 350t by this structure.When forging exceedes the workpiece of dish diameter, rotary table generally requires off center forging, so considerably increases spinning and forges man-hour, typically needs 2 ~ 3 fire just can complete mould pressing, and forging length in man-hour, efficiency are low, and energy loss is bigger.
Utility model content
This utility model is to solve problem present in above-mentioned FMT, it is provided that a kind of large diameter pipe plank-shaped forgings forging rotary table, reduces design and manufacture cost, shortens man-hour, put forward high efficiency purpose.
The technical scheme that this utility model is used by solving the problems referred to above is: large diameter pipe plank-shaped forgings forging rotary table, including support, all in cylindrical upper dish with revolution body, the center of revolution body is provided with centre bore, the lower surface of upper dish is provided with convex shoulder and the rotating shaft being connected with described centre bore, and the end face diameter being positioned at the upper dish above convex shoulder is more than the end face diameter of revolution body；Described support is wrapped on the portion perimeter face of revolution body, in the arcwall face consistent with revolution body peripheral face shape inside support, the inner edge of pedestal upper end in the concave arc surface consistent with shoulder form, and the upper surface of support and the lower surface of upper dish, convex shoulder lateral surface between the matched in clearance consistent in spacing.
Further, the fit clearance between the lateral surface of the upper surface of support and the lower surface of upper dish, convex shoulder is 3 ~ 6mm.
In this utility model, the outside of support is provided with two and hangs handle.
In this utility model, the side face being positioned at the upper dish above convex shoulder is provided with multiple lifting eye.
In this utility model, the end face diameter being positioned at the upper dish above convex shoulder is 5500 ~ 7000mm.
Rotary table of the present utility model uses the structure of upper dish+support+revolution body, and its revolution body uses existing rotary table structure.Wherein, upper dish is replaceable, and cylindrical leaves step, and circumference has lifting eye, and diameter exceeds former revolution body；Having the arc surface being consistent with revolution body radius inside support, handle is hung at the two ends of stent outer.
Beneficial effect: 1, the fit clearance between upper dish and support is 3 ~ 6mm, under anvil has after pressure, gap-closing, upper dish engages with support, and support bears pressure；Under free state, gap is recovered, and upper dish separates with support, can flexible rotating.
2, rotary table is when carrying out spinning forging, a diameter of 5500 ~ 7000 tube sheet forging moldings can be realized flexibly, described rotary table is utilized to have upper dish and supporting structure, frock light weight, flexible rotation, the reliable feature of support, spinning process is without carrying out off center forging, reduce frock gross mass 100 ~ 150t, pressure-bearing maximum is up to 185MN, reduce design and manufacture cost, shorten man-hour, improve efficiency, use described rotary table can realize 1 fire and complete the mould pressing of large diameter pipe plank-shaped forgings, reduce fire.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
Large diameter pipe plank-shaped forgings forging rotary table as shown in Figure 1, the tube sheet type heavy forged piece of a diameter of 5500 ~ 7000mm can be forged, including support 2, upper dish 1 and revolution body 3, upper dish 1 and revolution body 3 are all in cylinder, revolution body 3 is tradition rotary table rotating part, the center of revolution body 3 is provided with centre bore, and the central axis of revolution body 3 is arranged with the central axes of upper dish 1.As in figure 2 it is shown, the lower surface of upper dish 1 is provided with convex shoulder 4 and the rotating shaft 5 being connected with described centre bore.
As shown in Figure 1, the side face being positioned at the upper dish 1 above convex shoulder 4 is provided with multiple lifting eye 6, the end face diameter being positioned at the upper dish 1 above convex shoulder 4 is more than the end face diameter of revolution body 3, and support 2 is wrapped on the portion perimeter face of revolution body 3, and the end face diameter of support 2 is not less than the end face diameter of upper dish 1.Wherein, as shown in Figure 3 and Figure 4, in the arcwall face 20 consistent with revolution body 3 outer peripheral face shape inside support 2, the inner edge of support 2 upper end is in the concave arc surface 21 consistent with convex shoulder 4 shape, and the upper surface of support 2 and the lower surface of upper dish 1, convex shoulder 4 lateral surface between the matched in clearance consistent in spacing, preferably, this fit clearance is 3 ~ 6mm.Wherein, be positioned at the diameter range 5500 ~ 7000mm of upper dish 1 above convex shoulder 4, expand work surface, replaceable according to forging tubesheet specification, the upper dish 1 of support 3 and different size with the use of, altitude range is 1000 ~ 1500mm, pressure-bearing maximum 185MN.
