Abstract

The invention relates to a flexural coupling resonance type vibratory stress relief device and an implementation method thereof. A fixed support table of a workbench of the flexural coupling resonance type vibratory stress relief device is fixed on a base and is provided with a fixed support sliding bearing; a sliding stand is installed on a sliding rail; a sliding stand support bearing is arranged on the sliding stand; one end of a screw rod is connected with the fixed support table, and the other end is connected with a base baffle after penetrating through the sliding stand; the base baffle is provided with a sliding stand setting dial; a motor of the speed-adjustable main transmission system is installed on the base and connected with a reducer through a motor coupling; the output endof the reducer is connected with a universal coupling through a main coupling; the other end of the universal coupling is connected with a workpiece holder; the workpiece holder locks a workpiece; the eccentric weight is installed on the workpiece; and a torsion increasing device is fixed on the sliding stand. The invention can effectively solve the problem that a large-size high-rigidity workpiece can not be easily subjected to vibratory stress relief treatment.

Description

technical field [0001] The invention relates to a vibration aging device in the technical field of mechanical processing, in particular to a bending-torsion coupling resonance type vibration aging device and a realization method thereof. Background technique [0002] Vibration aging treatment is a method commonly used in engineering materials to eliminate their internal residual stress. Through vibration, when the vector of residual internal stress and additional vibration stress in the workpiece reaches or exceeds the yield strength of the material, the material undergoes a small amount of plastic deformation. , so that the internal stress of the material can be relaxed and relieved. Compared with thermal aging, vibration aging has the advantages of less investment, quick effect, low operating cost and environmental protection. Therefore, the high technology of vibration aging has broad application prospects. [0003] The excitation frequency of the existing vibration agi...
