A method of manufacturing a multi-dimensional curved tapered tube

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...

[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 shape is 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; burning acetylene pollutes the environment and is not environmentally friendly; the workers are in a high temperature environment during production, and the safety is poor

Moreover, the traditional hot bending manufacturing has a large amount of deformation, and the error of the external dimension is large and unsightly. Repeated manufacturing adjustments cannot be formed at one time, and a bending mold is required, which wastes manpower and material resources.
