Embodiment 1

[0043] Such as Figure 1-10 Shown, a kind of manufacturing method of multi-dimensional curved tapered pipe, comprises the following steps:

[0044] Step 1: Use 3D design software to design the digital model of the multi-dimensional curved conical tube that needs to be manufactured. The lower end of the multi-dimensional curved conical tube with the largest cross-sectional area is closed by a plane regular hexagonal bottom plate, and the plane regular hexagonal There is a specific mark designed near each side of the bottom of the bottom plate. The mark here is only for identification. As long as it can distinguish the mark, it can be used. The multi-dimensional curved cone connected to the edge of the plane regular hexagonal bottom plate The lower part of each side wall outside of the shaped tube is designed with the same mark, and the side walls with the same mark are connected to the edge of the bottom plate with the same mark.

[0045] Step 2: Use the surface development co...

Embodiment 3

[0069] As a preferred embodiment, the difference from Embodiment 1 and Embodiment 2 is that, as Figure 1-10 Shown:

[0070] Particularly preferably, the three-dimensional design software used in the step one is Catia three-dimensional design software, and the order used in the second step is the surface expansion command in the GSD module of CAIA.

[0071] Particularly preferably, the thickness of the steel plate used in the third step is 1mm-5mm.

[0072] Particularly preferably, the welding method in steps 4 to 7 is argon arc welding.

[0073] Particularly preferably, in the fifth step and the sixth step, when welding the two side walls together, the welding starts upward from the position close to the bottom plate.

[0074] Particularly preferably, in the seventh step, the high-pressure steel pipe is welded to the upper end of the multi-dimensional curved tapered pipe.

[0075] Particularly preferably, in the seventh step, the maximum pressure that the high-pressure wat...

Abstract

The invention discloses a manufacturing method for a multidimensional curved conical tube. The manufacturing method includes that the multidimensional curved conical tube is designed by adopting three-dimensional software, surfaces are separated and unfolded into planes, accurate cutting is achieved, and waste of materials is reduced; fixing with a traditional steel frame is not needed, welding and assembling operations can be performed on the ground to have the surfaces welded, and waste of the steel frame used for one time is reduced; the cross section of the multidimensional curved conical tube is rounded by the aid of pressure of water, production process is simplified, high-temperature machining is avoided, and problems about high-temperature scalding, positioning difficulty, big errors and the like are effectively solved. The waste of the materials is lowered, the process is simplified, industrial accidents are reduced, leveraging of multiple processes is avoided by one-time formation, production efficiency is improved, use of fuel is reduced, and safety and environment friendliness are achieved.

Description

technical field [0001] The invention belongs to a method for manufacturing a tapered pipe, in particular to a method for manufacturing a multi-dimensional curved tapered pipe. Background technique [0002] In the field of urban sculpture, multi-dimensional curved conical tubes are often used to express. The traditional method of this kind of conical tubes is to fix the straight conical tubes on a special The steel frame is softened with an acetylene flame and bent to the required curvature. The temperature is difficult to control, and the bending force depends on the experience of the workers. The curvature is not accurate, the error is large, and the product quality is poor; it consumes a lot of fuel. The required shapes are different, the steel frame cannot be reused, the scrap rate of materials is high, the production efficiency is low, the production cycle is long, and the production cost is high; the burning of acetylene pollutes the environment and is not environmental...
