Inner and outer arc-shaped template linkage mechanism and equipment for steel tube bearing and flaring mouths

Abstract

The invention discloses steel tube bearing and flaring mouths manufacturing equipment which operates through digital control. A production process is optimized and digital control operation reliability is improved for different specification dimensions and different material requirements of steel tube bearing and flaring mouths according to different mechanism structural features and processes, sothat the sizing dimensions of the steel tube bearing and flaring mouth are more precise. The inner and outer arc-shaped template linkage mechanism can realize manufacturing of steel tube bearing andflaring mouths of different pressure grades, can realize automatic operation under digital control, is high in efficiency, is high in production speed, and can meet continuous manufacturing and producing needs of the steel tube bearing and flaring mouths with diameters of 300-4000 millimeters within a pressure grade range of 2.0 MPa.

Description

technical field [0001] The invention relates to a production technology of steel pipe flaring manufacturing equipment, specifically a linkage mechanism, equipment and combination line of inner and outer arc templates for steel pipe flaring. Background technique [0002] The steel pipes involved in this background technology refer to spiral welded steel pipes, straight seam welded steel pipes and seamless steel pipes with diameters ranging from 300 mm to 4000 mm. [0003] In view of the high strength of the steel pipe and the difficulty of making the socket flare, the traditional steel pipe socket manufacturing process is difficult to meet the watertightness requirements required by the project. Judging from the content disclosed in Chinese patent ZL201721694961.2, although there have been breakthroughs in structure and technology, there are also deficiencies in unreasonable structural design and digital control, and it is difficult to meet the requirements of factory product...
