Tube rolling forming is the core processing procedure for aerospace thin-walled metal pipelines. Many manufacturers are faced with problems such as uneven wall thickness, poor pipe roundness, low production speed and high tool loss during long-term production. This guide summarizes key practical methods to upgrade rolling quality and workshop productivity.
Choose matched mandrel & roller tooling according to tube material, diameter and wall thickness. Hardened alloy steel tooling with precise grinding can reduce inner pipe scratches and dimensional deviation.
Adopt closed-loop pressure-controlled automatic rolling equipment instead of traditional manual machines, to guarantee consistent extrusion force in each rolling cycle.
Set segmented rolling parameters step by step for super-long bent pipes, avoiding one-time excessive expansion leading to pipe deformation.
Carry out regular maintenance for spindle, guide rail and transmission parts, timely replace worn tool accessories to keep long-term stable machining precision.
Establish standardized parameter archives for each pipe specification, shorten debugging time when switching different products.
Reasonable matching of equipment, tooling and processing parameters can not only greatly reduce product rejection rate, but also raise overall workshop output and lower comprehensive production costs for aerospace pipeline workshops.
