The invention discloses an assembly tool and an assembly method for stainless steel spherical tank spherical shell parts which are resistant to welding deformation. Press template and fixture, the lower press template, stainless steel spherical tank shell plate and upper press template are sequentially laid on the tire frame from bottom to top and clamped and fixed together by the clamp, the upper press template is used for opening In order to weld the pillar of the spherical tank to the opening on the stainless steel spherical tank shell, the upper surface of the lower pressure template and the lower surface of the upper pressure template are respectively matched with the inner surface and the outer surface of the stainless steel spherical tank shell, so The upper surface of the tire frame matches the lower surface of the lower pressing template. Since the deformation of the stainless steel spherical tank shell plate is limited by the upper and lower pressure templates and the tire frame during the welding process of the stainless steel spherical tank shell plate and the spherical tank pillar, the deformation of the stainless steel spherical tank shell plate is effectively controlled, and its geometric dimensions Meet the design requirements.
Description
technical field [0001] The invention relates to an assembling tool and an assembling method for the spherical shell parts of a stainless steel spherical tank which are resistant to welding deformation. Background technique [0002] At present, relatively large stainless steel spherical tanks are spliced by several stainless steel spherical tank shell plates. When a certain stainless steel spherical tank shell plate needs to be welded with a spherical tank support (or called a spherical tank support leg), it is necessary to weld the spherical tank support to the stainless steel spherical tank shell plate before the overall splicing. [0003] Since the shell plate of the stainless steel spherical tank is relatively thin, the shell plate of the stainless steel spherical tank will have a large deformation when welding the pillars of the spherical tank and welding the nozzle on the shell plate of the stainless steel spherical tank, which seriously affects the curvature quality ...
