The invention relates to a method for manufacturing a corrugated heat exchange tube, which includes the following steps: (1) constructing a model of the corrugated tube shape parameters; (2) using the principle of space envelope to design the cross section of the roller, and obtaining the contact line and the cross section of the roller shaft; 3) Use CNC machining simulation software to build machine tools and perform simulation; (4) Compare the simulation results with the ideal size bellows, and evaluate the deviation; (5) Determine tool parameters and processing parameters; (6) Use finite element analysis software for simulation, Calculate the springback of the pipe wall; (7) Use a rolling machine for processing. In this method, the mathematical model of corrugated pipe processing is established, the contact line and the section of the roller shaft are obtained by using the space envelope principle, and then the simulation software is used to simulate the processing of the corrugated pipe, and the tool parameters and processing parameters are optimized by comparing with the ideal size corrugated pipe. Finally, a rolling machine is used to process bellows with good quality and high performance.

Description

technical field [0001] The invention relates to a processing method for the surface of a pipe fitting, in particular to a manufacturing method for processing the surface of a corrugated heat exchange tube. Background technique [0002] The heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid, so that the temperature of the fluid reaches the specified index of the process flow. The heat exchange tube is the core component of the heat exchanger. High-performance heat exchange tubes, and corrugated heat exchange tubes are a common high-efficiency enhanced heat exchange tube. How to improve the manufacturing quality and performance of corrugated heat exchange tubes has always been the focus of research in the field of heat exchangers. [0003] At present, the traditional corrugated heat exchange tube is processed into a corrugated shape by a wave squeezer equipment. The product processed by the production process is a straig...
