Embodiment Construction
[0025] The embodiments of the present invention will be further described in detail with reference to the drawings.
[0026] see figure 1 , A method for processing and manufacturing spatial multi-curved intersecting round pipes. The new version of the sample drawing of spatial multi-curved intersecting round pipes. Compared with the conventional drawings, the docking datum point is added, and the inner arc point of the curved circle and the site installation datum are correspondingly reflected. The relative positional relationship between the points and the docking reference point, where the middle circular tube is placed horizontally and symmetrically, and the inner arc point coincides with the docking reference point of the circular tubes on both sides;
[0027] Program the intersecting line according to the drawing, and specify the docking datum point as the starting point;
[0028] After the pipe intersecting line is cut, mark the position of the starting point and draw the cente...

The invention discloses a space multi-bend interaction circular pipe machining and manufacturing method. The method comprises the steps that 1, a deepen drawing is renovated, a circular pipe butt connection datum point is embodied in the assembly drawing, and a bent circle inner arc point and a site installation datum point (site installation connection position highest point) are correspondinglymarked, wherein middle circular pipes are horizontally and symmetrically placed; 2, a cutting start position of a circular pipe interaction line program is designated as the first circular pipe butt connection datum point; 3, the working procedure of marking the inner arc point and the site installation datum point on the outer side of the circular pipe is added, and a site positioning hoisting lug plate is added; and 4, the splicing technology is adjusted, and the efficiency and precision are greatly improved. The problems that multi-bend interaction circular pipe machining and manufacturingdifficulty is large, precision is low, and site installation difficulty is large are solved.
Description
Technical field [0001] The invention belongs to the field of steel structure buildings, and relates to a steel structure component, in particular to a method for processing and manufacturing spatially multi-curved circular pipes. Background technique [0002] In recent years, domestic large-scale airports, railway stations and Olympic stadiums and other related steel structure buildings, with the rapid development of the domestic economy and the development of steel structure technology, the structure has become more diverse and the appearance is more beautiful, which has brought a great deal to the production process of steel structure factories. Challenges. This includes the production of components with multi-curved intersecting circular pipe structures. [0003] There are three difficulties in the production of this structure: 1. The intersection is a special-shaped curved surface, and it is difficult to find an accurate base point to bend the pipe; 2. The curved surface of th...
