ABSTRACT:
An apparatus (20) for induction heat treating, restraint quenching, and straightening an associated carbon steel truck structural member (30), having a web (32) and at least one flange (34) substantially perpendicular thereto, comprises a heat treating apparatus (22) for induction heating and restraint quenching the associated structural member (30). The heat treating apparatus (22) is operatively connected to a cooling conveyor (50). The cooling conveyor (50) is adapted for receiving the associated structural member (30) from the heat treating apparatus (22). A testing apparatus (24) is included for hardness testing the heat treated associated structural member. The testing apparatus (24) is adapted for receiving the associated structural member (30) from the cooling conveyor (52). A conveyor (54) is adapted for receiving the associated structural member (30) from the testing apparatus (24). A roller straightener (26) is operatively connected to the conveyor (54). The roller straightener (26) is adapted for receiving the associated structural member (30) from the conveyor (54). The roller straightener (26) has at least three rolls (64b, 64c, 64d) proximately located to one another for operatively engaging the associated structural member (30) between the rolls. The roller straightener (26) further includes an apparatus (78) for adjusting the position of at least one of the rolls (64) along a first axis.
