METHOD FOR MANUFACTURING A STAMPED/HEATED PART FROM A STEEL SHEET PLATED WITH ALUMINUM ALLOY
摘要:
A method and related apparatus are disclosed for heating and stamping a processed part. A sheet of high-tensile steel is provided as a work part. The sheet is plated with a high-temperature-resistant material to improve formability. The temperature-resistant material can include oxidized aluminum or a high-temperature-resistant alloy of aluminum and/or zinc and/or steel. An electrical current is applied to the work part to provide heating to the work part through resistance heating. The plated sheet can be stamped while heating to form a stamped work part. The work part is quenched through cooling to increase metallurgical strength.
