Abstract

The invention discloses a simulation model verification and establishment method and application in the welding production process of thin-walled copper pipes, belonging to the field of thin-walled copper pipe production. The present invention utilizes DEFORM to calculate the temperature distribution in the production process of the thin-walled copper pipe, and calculates the microhardness value of the test piece through experimental measurement, and compares the measurement result with the microhardness value of the thin-walled copper pipe sample actually produced by the factory, Indirect verification of temperature distribution to ensure correct calculation results. Compared with the existing simulation technology, the present invention calculates the temperature field under different influencing factors by changing the parameters affecting the heating temperature, so as to optimize the production parameters, improve the production quality, reduce the equipment production and debugging cycle, and reduce the cost.

Description

technical field [0001] The invention belongs to the field of thin-walled copper pipe production, and relates to a simulation model verification method, establishment method and application in the thin-walled copper pipe welding production process. Background technique [0002] Thin-walled copper tube refers to a copper tube with a ratio of outer diameter to wall thickness greater than 20. It has many characteristics: it can withstand heat, cold, pressure, corrosion and fire, has a wide range of applications, and has high reliability; the same The calculated inner diameter of the copper pipe with the nominal diameter is larger than that of other pipes. Under the same flow rate in the pipe, the flow rate of the copper pipe is lower, so the copper pipe can save energy and reduce noise; the copper pipe has a long service life, reaching more than 100 years; the copper pipe can inhibit Bacterial growth, good antibacterial and impermeable; copper pipes are green and environmentally...
