Structural design of automatic pipe-making machine for automobile exhaust pipeline tubing
摘要
Abstract
To tackle the key limitations of traditional automobile exhaust pipe manufacturing—high labor dependency,unstable forming quality,low production efficiency,and inability to meet the demands of industrial large-scale produc-tion—this paper presents the design of a highly automated automatic pipe-making machine for automobile exhaust pipes.The machine is mounted on an operating platform,with a pipe-matched arc-shaped support pallet for precise and stable positioning.It integrates three core forming units(shaping,flaring-expanding,and pressing),and is e-quipped with a fully automatic loading and unloading system consisting of a conveyor belt and ejection assembly.A syn-ergistic processing technology integrating internal supporting shaping and external pressure forming is adopted,and the design rationality of the core mechanism is validated through finite element simulation.The proposed equipment enables the one-step forming of pipe flat port,delivers outstanding finished product consistency,and significantly cuts down la-bor dependence.Featuring a compact overall layout,it is adaptable to the processing of pipes with various specifica-tions,which provides solid technical support for the automated mass production of automobile exhaust pipelines.关键词
