Specific embodiment
Specific embodiment: quasi- hemispherical head of certain pressure vessel head having a size of SR1415 × 69 (60), specific structure
See attached drawing 4, wherein internal diameter Dn=2800mm at quasi- hemispherical circumferential weld groove, depth H=1211mm (is less than SR1415 inside radius
204mm), need newly to obtain through refining non-standard SR1415mm hemispherical head plunger chip die as usual, see Fig. 5, in Fig. 5 in quasi- hemispherical envelope
Head by the compacting of whole hemispherical head, straight side length h1=20mm, circumferential weld surplus h3=224mm, steel plate blank dimension is
Certain torispherical end socket plunger chip die technical process: technical process: the oxygen-acetylene cutting of steel plate blank, 1/2 are spelled
Weld → obtain through refining SR1415 integrally quasi- hemispherical head plunger chip die → hot pressing end socket → gas cutting circumferential weld surplus → vehicle circumferential weld groove.
Using technical solution of the present invention:
In the present embodiment, the quasi- hemispherical head plunger chip die of the bearing device of technical solution of the present invention and manufacturer
Method can use existing idle SR1400 standard hemispherical head plunger chip die, seal in idle SR1400 standard hemispherical
Local surfacing insert, end socket compacting, which thicken, on head plunger chip die deviates plunger chip die L for the about 7mm of plate thickness 10%, insert cylindrical surface
It takes 4mm, make to suppress to thicken suitably to be distributed in end socket inner surface, insert cylindrical surface and spherical surface intersection corner changeover portion arc surface half
Diameter ri takes 400mm, and head skirt height or circumferential weld surplus h2 take 30mm, be computed, steel plate blank diameter size
See Fig. 6.
Certain quasi- hemispherical head plunger chip die manufacturing method technical process: existing plunger chip die on positioner, it is pre-
Heat, built-up welding insert → annealing heat-treatment → machine add under insert cylindrical surface, spherical surface, corner changeover portion arc surface → steel plate blank gas cutting
Material, 1/2 welding → hot pressing end socket → gas cutting circumferential weld surplus → vehicle circumferential weld groove and inner surface surplus or transition.Hot pressing dome head
The edge effect that end circumferential weld is inclined outwardly causes internal diameter bigger than normal, therefore will there are more than no small circumferential weld when previous pressing seal head
Amount；Due to this patent innovation plunger chip die special designing, eliminating edge effect influences, reduces pressing seal head circumferential weld
Surplus and blank size will be thickened at the circumferential weld of pressing seal head end and be suitably distributed in inner surface, so that circumferential weld inner surface can be with machine
Add finishing, the geometric tolerances such as circumferential weld circularity, unfitness of butt joint, inner diameter deviation be improved significantly.
Reference example and technical solution of the present invention are compared, it is not difficult to find out that, the quasi- hemispherical head production of same size, wherein
The steel plate blank dimension that original method uses isThe steel plate blank dimension for using the technical program to use for Die sinking expense can be saved using the technical program simultaneously；End socket steel plate materials are reduced compared with existing production technology
Mold manufacturing expense is saved in consumption 13%, improves circumferential weld groove quality.
