Abstract
1445230 Vehicle bumper bars HOUDAILLE INDUSTRIES Inc 8 May 1974 [17 May 1973] 20336/74 Heading B7J A bumper bar is formed from easily workable sheet or strip steel and selectively heat and quench hardened along its face 15 and flanges 17, 18, there being portions of the flanges adjacent the face which are free of heat and quench hardened. Alternatively, a reinforcement bar is selectively heat and quench hardened and a decorative face bar secured to it (Fig. 5, not shown). Reinforcing straps may interconnect the free ends of the bumper bar. The sheet or strip steel stock has a carbon content in the range 0À12 to 0À17% The bumper bar is heated to 1650‹F to 1700‹F in about 15 seconds and quenched to about 70‹F in about 0À2 to 0À3 seconds, quenching water being applied for some 9 seconds. Apparatus for hardening the bumper bar comprises a fixed male die 28 for receiving a bumper bar, flame heads 37 mounted on reciprocating carriers 32, 33 and a movable female die for pressing the bumper bar against the male die during quenching. Spring-loaded plungers hold the bumper bar clear of the male die during heating to minimize dissipation of the heat through the die. Quenching water is supplied to the bumper bar through passages in the dies. In an alternative arrangement, the flame heads are replaced by induction heating coils in the female die, the female die being lowered to press the bumper bar against the male die from the outset.
