The invention discloses a metal profile parallel roller straightening machine, and relates to the technical field of metal profile machining, the metal profile parallel roller straightening machine comprises a placing frame, a feeding limiting assembly, a power conveying assembly, a driving assembly, a profile straightening mechanism and a straightening fixing assembly, and the feeding limiting assembly and the power conveying assembly are both arranged at one end of the outer side wall of the placing frame; the driving assembly is arranged in the placing frame, the number of the sectional material straightening mechanisms is two, the two sectional material straightening mechanisms are movably arranged on the outer side wall of the placing frame, the straightening fixing assembly is arranged in the placing frame, and the working end of the straightening fixing assembly corresponds to the two sectional material straightening mechanisms; the problems that in the prior art, due to the fact that the metal profiles are long and different in specification, machining equipment is different in size, when the metal profiles enter a straightening machine and move into the machining equipment, too many positions of the metal profiles are suspended and shake, and the straightening effect of the metal profiles is poor are solved.
