Title:
PLASTIC WORKING METHOD FOR WORKING-RESISTANT METAL
Document Type and Number:
Japanese Patent JP2023057806
Kind Code:
A
Abstract:
To provide a plastic working technique capable of increasing deformation performance of cold compression plastic deformation for a working-resistance metal of low ductility.SOLUTION: A plastic working method for a working-resistance metal, which plastic deforms the working-resistance metal as a material to be worked through cold compression, compresses the material to be worked at a prescribed speed v (mm/sec.) from a vertical direction, and plastic deforms the material to be worked cold by simultaneously adding a compression force to the material to be worked and reciprocating and vibrating the material to be worked with prescribed amplitude α(°) at a prescribed rotational speed ω(°/sec.) around a rotational axis of the material to be worked to add both-oscillation torsion vibration caused by a both-oscillation torsion force.SELECTED DRAWING: Figure 1
