Description

Stress relieving device

Technical Field

The utility model relates to a stress relief device belongs to vibratory stress relief device technical field.

Background

The vibration ageing treatment is a method for eliminating the internal residual stress of engineering materials, and the essence of the vibration ageing is that a dynamic stress is applied to a workpiece in a vibration mode, when the dynamic stress is superposed with the residual stress of the workpiece and reaches or exceeds the microscopic yield limit of the materials, the workpiece can generate microscopic or macroscopic local and integral elastic plastic deformation, and simultaneously, the residual stress in the workpiece is reduced and homogenized, and finally, the purposes of preventing the deformation and cracking of the workpiece and stabilizing the size and geometric accuracy of the workpiece are achieved.

Most of the prior vibration aging methods are to mount a motor system (called an exciter) having an eccentric weight on a member, support the member by an elastic body such as a rubber pad, and start the motor and adjust the rotation speed of the motor by a controller so that the member is in a resonance state. But has certain limitation or unsatisfactory aging effect on small and medium-sized workpieces.

Detailed Description

The present invention will be further described, but not limited to, by the following examples in conjunction with the accompanying drawings.

Example 1:

as shown in fig. 1 to 2, the present embodiment provides a stress relief apparatus, which includes a base 2, a crankshaft 5, a vibration table 4, and a motor 1; shaking table 4 sets up in base 2 top, and motor 1 sets up in base 2 bottom, and motor 1 passes through bent axle 5 and connects shaking table 4. Four springs 3 are arranged between the vibration table 4 and the base 2.

Wherein, base 2 is the rectangle and center department has seted up the through-hole, and motor 1 passes through bolt fixed mounting and puts at the central point of base 2 bottom, and the output shaft of motor 1 passes the through-hole.

The shaking table 4 is rectangular, nine parallel T-shaped grooves 41 are formed in the upper surface of the shaking table 4, a groove is formed in the center of the bottom of the shaking table 4, and a bearing 6 is installed in the groove.
