Abstract
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.
Claims20
An apparatus for simultaneously heating and stamping a processed part comprising:
- a resistance heating assembly that applies an electrical current to a work part comprising a sheet of high-tensile steel having a heat-resistant plating to improve formability;
- a stamping assembly that stamps the plated sheet simultaneously during resistance heating to form a stamped work part;
- and
- a quenching bath that quenches the work part through quick cooling to increase strength.
A method of simultaneously heating and stamping a processed part comprising:
- providing a sheet of high-tensile steel as a work part;
- plating the sheet with a high-temperature-resistant plating material to improve formability;
- applying an electrical current to the work part to provide heating to the work part through resistance heating;
- stamping the plated sheet to form a stamped work part;
- and
- quenching the work part through quick cooling to increase metallurgical strength.
An apparatus for simultaneously heating and stamping a processed part comprising:
- means for applying an electrical current to a work part to provide heating to the work part through resistance heating, wherein the work part comprises a sheet of high-tensile steel plated with a high-temperature-resistant material to improve formability;
- means for stamping the plated sheet while heating to form a stamped work part;
- and
- means for quenching the work part through cooling, wherein cooling increases metallurgical strength.
