s1: grading the material with linearity deviation according to H/S = M ‰, wherein the M value is within 1, the T-shaped pultrusion piece (10) is qualified, the T-shaped pultrusion piece (10) can be straightened when the M value is between 1 and 7, the M value is greater than 7, and the T-shaped pultrusion piece (10) cannot be straightened and is unqualified;
wherein H is the straightness deviation value of the T-shaped pultrusion piece (10); s is the length of the T-shaped pultrusion piece (10);
s2: and independently straightening each section of the T-shaped pultruded part (10), namely straightening the T-shaped pultruded part (10) once in the heat preservation box (3) when the T-shaped pultruded part advances one section until the rest T-shaped pultruded part (10) can not be conveyed.
6. The control method of the automatic straightening device for the T-shaped pultruded part according to the claim 5, characterized in that after the movement of each T-shaped pultruded part (10) is finished, the setting temperature of the hot air blower is determined by the position of the linear ruler (38), and when the position of the linear ruler (38) is the reference position, the straightening of the T-shaped pultruded part (10) is finished.
