The invention relates to the technical field of
cooker forming manufacture, and provides a
titanium-aluminum-steel composite pan stretching tool and a stretching forming method. The stretching tool comprises a stretching female die and a stretching male die matched with the stretching female die; a stretching gap for placing a piece to be stretched is formed between the stretching female die and the stretching male die; the piece to be stretched in placed into the stretching gap, and is a
titanium-aluminum-steel three-layer composite piece; the stretching female die comprises an upper die base and a push rod arranged on the upper die base; the stretching male die comprises a lower die base and a binder ring arranged on the lower die base; and a limiting
dowel is further arranged on the binder ring, and adjusts the size of the stretching gap, so that the size of the stretching gap is larger than the thickness of the piece to be stretched. The method comprises the steps of
coating lubricating oil, adjusting the gap thickness, moving and stretching, and forming a mold. The
titanium-aluminum-steel composite pan stretching tool and the stretching forming method solve the problems of material fracturing and wrinkling during a production process of a titanium-aluminum-steel three-layer composite pan, and meanwhile, with the three-layer arrangement, the problems of safety,
heat transfer and application environment are solved.
