Therefore, the design conditions of the batch and the 5th are often ignored. However, the cause of this residual is It may be that the mLI is connected to the defect and the deformation of the b θ k is deformed, resulting in the actual strength and fatigue limit of the component when the component is joined and assembled, causing problems such as stress decay and brittle fracture and easy cracking of the material.

The method of removing residual stress by heating 4 is called stress relief annealing (ess Rellef Annealmg). The heat is mainly heated at a suitable temperature (recrystallization temperature), and then the temperature is maintained for a period of time to cause the workpiece to recrystallize at a high temperature. The grains re-grow and release the stress remaining inside the material. . However, this method must accurately control the heating temperature, holding time and cooling rate of 1281502, 'in order to completely release the residual to increase the residual stress, not only equipment =: = uneven 'anti-limit, the damage is more expensive, the process...: When the size of the ground is treated, it is necessary to consider the problem of the overall hardness τ drop, and the post-treatment between the heat and the oxide film and the protective atmosphere in the furnace is that it is almost the most difficult to control after heat treatment. ...the law avoids distortion. In order to represent the = method, the method of removing the residual stress can be hammered (Peeking, if the bell is hit by the floating channel of the Xue, the tensile stress produced on the surface of the fresh road.

Stable control' In addition, the vibration stress is fresh and produces the effect of the aging effect (agmg), which can effectively reduce the rigidity and resist deformation, so that the processability becomes more excellent. The vibration elimination stress mainly comes from two energy sources. The first is the main wave that drives the workpiece to jump. This main wave does not help the stress elimination. The other is the secondary wave (high frequency resonance wave) acting on the workpiece and the alternating stress. The frequency of this wave Higher, lower energy' is motivated by the main wave, but it is a good glimpse of the stress-relieving effect. Only the 'secondary wave' changes with the main wave. Therefore, it is necessary to strengthen the secondary wave by 1281502. Therefore, it is difficult to eliminate the effect of the earthquake, so the effect of eliminating the stress of the shatter is greatly reduced. [Invention] Therefore, the object of the present invention is the multi-frequency (four) unit of the wave. High-frequency common vibration two! Set: The invention of the complex-frequency resonance unit is composed of two vibrators. The vibrations σ▽疋5 are placed at different positions of the workpiece, and B8 can be separately in the vibration, different frequencies. , the small scale ice, the flat, the tens of thousands of spoons of the vibration wave interaction to produce high-frequency white deletion., handed to the workpiece. By this, 'enhance the high-frequency resonance wave (ie, the second wave) [real:;:; The effect of eliminating the residual stress. The foregoing and other technical contents related to the present invention will be described below with reference to the drawings, and the effect is clearly shown.

Γ七曰' not only enhances the amplitude of the high-frequency resonance wave, but also can improve the effect of the 'remaining stress, so that the workpiece also stays and effectively releases energy during the high-frequency resonance ^(4)—10 minutes, -: Second (10), the configuration of the vibrators '1 may also be in the same position along the axis direction with the X=L, or respectively along the 2 mz as the ancient a α at different positions of the workpiece 4, or on: The direction of the x-axis is set at a different position of the workpiece 4, and the resonance wave is generated in the vertical direction and the vertical direction, or in the horizontal direction. Hunt this, can match the waveform of different workpieces 4, . Further, when the 高频-direction high-frequency resonance wave causes the single-sound disk to fail to be formed, the operator can generate a resonance wave with the oscilloscope 3 and the oscilloscope 3: It can be seen that the multi-frequency resonance unit of the present invention has the following advantages and effects. 1281502 The present invention can generate a mixed shocking effect on the workpiece 4 in a multi-frequency resonance manner, which not only enhances the high-frequency resonance wave ( The amplitude of the secondary wave creates a waveform that cannot be formed by a single oscillation, and can also improve the residual stress elimination effect. The acceleration gauge 2 and the oscilloscope 3 measure and display the timing of the resonance frequency of the workpiece 4, not only the timing, but also the timing of the resonance of the workpiece 4 The utility model can effectively improve the elimination effect of the residual stress, greatly reducing the waste of energy, not being restricted by the construction site, and simplifying the procedure and reducing the cost, so that the invention is more practical and convenient.
