摘要： An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece.

C., immediately quenching the heated region to soften the region, and then performing the shearing operation in the softened region before age-hardening occurs.

摘要： The present invention provides a method of embossing or imprinting patterns in the surface of a sheet metal article using superplastic forming at suitable SPF temperatures. A template having a pattern is interposed between a forming tool and a sheet metal blank. Gas pressure is applied to the sheet metal blank. This pressure forces the sheet metal against the surface of the lower forming tool having the template there between. The sheet metal blank is stretch formed according to the contours of the surface of the lower forming press and the template. The embossed and shaped sheet metal part is then removed from the forming tool.
