[0002] Stress relief by aging is a specific process that eliminates or reduces residual stress generated during the processing of materials, thereby improving the performance and stability of the materials. By applying constant amplitude alternating cyclic excitation force to the workpiece through a vibration device, the workpiece undergoes plastic deformation in a resonant state, thereby eliminating and homogenizing residual stress.

[0003] A vibration aging device, disclosed in announcement number CN220812559U, includes a platform with a fixed frame on one side of its top. A fixing assembly is mounted on the fixed frame and includes a first adjusting rod, a sliding rod, a lifting plate, a pressure block, a bushing, a rotating shaft, a moving plate, a second adjusting rod, a threaded sleeve, a third adjusting rod, and a pressure plate. The first adjusting rod is rotatably mounted between the top and bottom front inner walls of the fixed frame, while the sliding rod is fixedly mounted between the top and bottom rear inner walls of the fixed frame. This technical solution allows for multi-point positioning of the parts, ensuring tight fixation between the parts and the platform during vibration aging treatment, improving the fixing effect, and thus guaranteeing the aging process. It is flexible and convenient to use.

[0023] See Figure 1-4 As shown, the high-frequency vibration device for stress relief of welded pipes according to this utility model embodiment includes a vibration platform 1, two mounting brackets 2, a mounting plate 3, a dual-axis motor 4, two openings 13, two guide plates 12, two first vertical plates 14, two second vertical plates 15, four second clamping blocks 16, two connecting plates 6, two first clamping blocks 9, two screws 8, and two guide rods 10. The vibration platform 1 drives the welded pipe to vibrate at high frequency. The two mounting brackets 2 are fixed to the upper end of the vibration platform 1. The mounting plate 3 is fixed between the two mounting brackets 2. The dual-axis motor 4 is fixed at the center of the upper end of the mounting plate 3, and screws 5 are fixedly connected to its output ends on both sides. The two openings 13 are respectively opened on the two mounting brackets 2. The two guide plates 12 are respectively fixed in the two openings 13. The two first vertical plates 14 are respectively movably sleeved with the two guide plates 12. The two second vertical plates 15 are located on one side of the two first vertical plates 14 and are respectively connected to the two guide plates 12. The guide plate 12 is movably sleeved; four second clamping blocks 16 are respectively fixed inside the two first vertical plates 14 and the two second vertical plates 15 to clamp the outer wall of the welded pipe; two connecting plates 6 are respectively fixed between the two first vertical plates 14 and the two second vertical plates 15, and are respectively threaded to the two screw rods 5; two first clamping blocks 9 are located at the bottom of the mounting plate 3 to compress the welded pipe; two screw rods 8 are respectively rotatably connected to the upper ends of the two first clamping blocks 9 and threaded to the mounting plate 3; two guide rods 10 are respectively vertically fixed to the upper ends of the two first clamping blocks 9 and movably sleeved to the mounting plate 3. The upper ends of the welded pipe are clamped by the two first clamping blocks 9, and the left and right sides of the welded pipe are clamped by the two second clamping blocks 16, which can effectively ensure the stability of the welded pipe during vibration, and can also adapt to welded pipes of various specifications, making it more adaptable to ensure the aging treatment effect of the welded pipe;

[0024] Both first clamping blocks 9 and two second clamping blocks 16 are V-shaped to clamp the welded pipe, which can accommodate welded pipes of various specifications and has greater adaptability.

[0025] The inner sides of the two first clamping blocks 9 and the two second clamping blocks 16 are provided with several toothed grooves 11 to enhance the friction between the first clamping blocks 9, the second clamping blocks 16 and the welded pipe, thereby further ensuring the stability of the welded pipe.

[0026] In use, the welded pipe is held between four second clamping blocks 16. Then, the dual-axis motor 4 is started, which drives two connecting plates 6 to move towards each other. The two connecting plates 6 then drive two first vertical plates 14 and two second vertical plates 15 to move towards each other, thereby making the four second clamping blocks 16 fit tightly against both sides of the welded pipe and limiting the welded pipe. Then, the two lead screws 5 are rotated. When the two lead screws 5 rotate, they drive the two first clamping blocks 9 to move down steadily. The two first clamping blocks 9 fit tightly against both sides of the upper end of the welded pipe. In addition, the pressure on the welded pipe is increased, thereby further ensuring the stability of the welded pipe. Finally, the vibration platform 1 is started to age the welded pipe.

[0027] The upper end of the vibration platform 1 is also provided with an auxiliary component 7, which includes a slide rail 71, two sliders 72, two baffles 75, two screw holes 73 and two bolts 74. The slide rail 71 is located at the upper end of the vibration platform 1; the two sliders 72 are slidably connected to the slide rail 71; the two baffles 75 are respectively vertically fixed to the two sliders 72 to clamp and fix the welded pipe; the two screw holes 73 are respectively opened on the two sliders 72; the two bolts 74 are respectively threaded into the two screw holes 73 to restrict the position of the sliders 72. The two baffles 75 are tightly fitted to both ends of the welded pipe to clamp the welded pipe and further enhance the stability of the welded pipe.

[0028] Both first clamping blocks 9 are on the same straight line as the two baffles 75, ensuring that the two baffles 75 can accurately and tightly fit with both ends of the welded pipe.

[0029] In use, push the slider 72, and the slider 72 moves stably within the slide rail 71. When the baffle 75 is in close contact with the end of the welded pipe, rotate the bolt 74. The bottom end of the bolt 74 will penetrate the slider 72 and fit tightly against the bottom wall of the slide rail 71, thereby limiting the position of the slider 72. This, in turn, makes the two baffles 75 fit tightly against both ends of the welded pipe, achieving the clamping effect on the welded pipe and ensuring the stability of the welded pipe during vibration.

[0030] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
