Plastic deforming device and method using the repeated torsion

摘要

The present invention relates to a firing part composed of at least one fired body and continuously arranged at regular intervals in the longitudinal direction of the metal material and performing twisting processing of the material; A motor for rotating the firing unit in an axial direction, and a power transmitting unit for connecting the firing unit and the motor to each other; A traction part for recovering the continuous supply of the material and the processed material; And a control unit for controlling the driving unit and the pulling unit, wherein the sintering body includes: a hollow hydraulic cylinder; a hollow chuck for pressing the material through the hydraulic cylinder or releasing the pressing through the hydraulic cylinder; And a driving unit installed between the hydraulic cylinder and the hollow chuck to rotate the hollow chuck in the axial direction. The present invention can be expected to increase the workability of the workpiece by continuously arranging the workpieces in the longitudinal direction at regular intervals and twisting the workpieces in the forward and backward directions at regular intervals to ultrafine the grain.
