Abstract: The method of making a heat treated aluminum alloy forging exhibiting reduced ''''oil-canning'''' in ''''oil-canning''''-susceptible sections upon machining, including bonding insulation onto an ''''oil-canning''''-susceptible section of an age-hardenable aluminum alloy forging with a bonding agent effective for maintaining a bond during heating for solution heat treatment, solution heat treating the thus-insulated forging, and, with the insulation still on the section, subjecting the solution heat treated forging to a quench for maintaining precipitable components of the alloy in solution in the ''''oil-canning''''-susceptible section, whereby upon machining, said section will exhibit reduced ''''oilcanning.

Abstract: A structure providing efficient gas heating of forging dies comprising a plurality of bearing bars made of a high strength metal located between the dies of a forging press and respective die supporting structures. The bars are spaced apart to accommodate gas fired burners and layers of heat insulation in such a manner that only the bearing bars receive forging loads, the layers of insulation and the burners, being accommodated in the spaces between the bearing bars, receive no forging loads. The bearing bars are provided with longitudinally extending openings for preheating and conducting the gas (or gas-air mixture) to the burners, and for limiting the conduction of heat from the dies to the die supporting structures. Each die supporting structure includes a plate or platen provided with slots adapted to receive and retain die clamping bolts, the bolts being located between adjacent bearing bars, and extending from the plate to and through respective clamps engaging the edges of the die and portions of at least two adjacent bearing bars extending beyond the edges of the die.

Abstract translation: 提供锻造模具的有效气体加热的结构，其包括由位于锻压机的模具和相应的模具支撑结构之间的由高强度金属制成的多个支承棒。 这些杆间隔开以容纳气体燃烧的燃烧器和隔热层，使得只有支承杆接收锻造载荷，绝缘层和燃烧器被容纳在轴承杆之间的空间中，不接收锻造载荷 。 轴承杆设置有纵向延伸的开口，用于将燃气（或气体 - 空气混合物）预热和传导到燃烧器，并且用于限制从模具到模具支撑结构的热传导。 每个模具支撑结构包括设置有适于容纳和保持模具夹紧螺栓的槽的板或压板，螺栓位于相邻的支承杆之间，并且从板延伸到并穿过与模具的边缘接合的相应夹具 至少两个相邻的支承杆延伸超过模具的边缘。
