Described T profile aligns one end of draw-in groove with T-shaped shape groove, the stile of this groove, base 1mm-3mm larger than the stile and base for the treatment of aligning T profile respectively.
Described cooling device is provided with T-shaped groove, the stile of this groove, base 0.5mm-2mm larger than the stile and base for the treatment of aligning T profile respectively.
Described base pin arranges pin-and-hole, and stile pin penetrates in the pin-and-hole of base pin and connects; Described base pin and stile pin, adopt pin/pin-and-hole mode to be interconnected therebetween.
To treat that on aligning T profile base, prefabricated base pin-and-hole aligns respectively with the axis that T profile aligns the base pin-and-hole of draw-in groove, penetrates base pin and connects; Aligning the pin-and-hole axial alignment on the stile pin-and-hole of T profile, the stile pin-and-hole of T profile aligning draw-in groove and base pin by waiting, penetrating stile pin and connecting.
Described T profile aligning draw-in groove, adopts thread connecting mode or pin/pin hole connection to be connected with straightener, or is directly snapped in the chuck of straightener.
Titanium alloy T sections aligning carry out under the high temperature conditions, cooling device be arranged at wait align T profile clip position near, the temperature near described T profile retained part to be aligned is not higher than 100 DEG C.
Advantage of the present utility model:
(1) stile of section bar and base are all connected by pin pin-and-hole, stretch and rotate section bar two ends, ensure stile and base deform in same pace and non-slip.
(2) cooling device is had near the position of titanium alloy profile bare terminal end, section bar retained part near zone can be made not by the impact of aligning part high temperature heat transfer, even if thus ensure that the stile of section bar and base are offered pin-and-hole but still retain the intensity higher than aligning part.
