Description

Technical field:

[0002] The rolling composite machine (abbreviated as composite machine) is a processing equipment specially used for forming thermal break aluminum profiles. At present, the rolling composite machine generally adopts three groups of rolling composite units to roll composite the thermal break aluminum profiles. The three groups of rolling composite units are arranged at intervals in the longitudinal direction. Each group of rolling composite units includes a fixed rolling mechanism and a dynamic rolling mechanism arranged at intervals in the transverse direction. The cutter disc on the dynamic rolling mechanism can be moved laterally to adjust the rolling spacing.
