Description

Technical Field

[0001] The utility model relates to the technical field of residual stress elimination of pipe fittings, in particular to a flexible residual stress elimination tool for long pipe fittings. Background Art

[0002] In the manufacturing process of semiconductor production equipment, the rack module is a key component, and its accuracy and stability have a vital impact on the performance of the entire equipment. However, in the preparation of the rack module, due to the existence of machining, heat treatment, welding and other processes, residual stress will inevitably be generated in long pipes and other components. Residual stress refers to the self-balanced internal stress that remains inside the object after eliminating external forces or uneven temperature fields. This internal stress may be caused by factors such as uneven plastic deformation, phase change or temperature gradient during heat treatment. In the preparation process of rack modules for semiconductor production equipment, these stresses may cause parts to warp, deform or even crack, seriously affecting the accuracy and stability of the rack module. Due to the particularity of thin-walled tubular workpieces in terms of materials and structures, the commonly used methods for eliminating residual stress are not applicable, such as rigid fixation method, mechanical impact, etc. Therefore, in recent years, a method of eliminating residual stress of workpieces using high-energy sound beams has been developed. This method does not produce impact, heating and other effects on the workpiece, does not affect the performance of materials and products, and is a stress elimination method that does not cause damage to the product;

[0003] The known authorized invention (publication number: CN117051228A) discloses a tooling that can eliminate residual stress of tubular workpieces of different diameters and lengths; the tooling of the present invention has a small overall volume, light weight, simple mechanical structure, and convenient operation for personnel. The ultrasonic transducer can be stably installed on the surface of the workpiece through a certain force to ensure that the sound energy is effectively transmitted into the workpiece, thereby achieving effective and lossless elimination of residual stress in the workpiece. At the same time, it can adapt to tubular workpieces of different diameters through structural adjustment. The overall tooling can be used as a single module form, and can be combined in an array along a linear direction to adapt to tubular workpieces of different lengths. The combination of the two has good flexibility, that is, it can adapt to different types of tubular workpiece products, which is beneficial to on-site production and practicality, and can save enterprise production costs and improve personnel work efficiency.

[0004] Although the device can be beneficial to on-site production and practical use, and can save enterprise production costs and improve personnel work efficiency when in use, the device needs to be equipped with multiple ultrasonic transducers when eliminating pipes of different lengths, which is very cumbersome and leads to low elimination efficiency. Therefore, a flexible residual stress elimination tool for long pipes is proposed. Utility Model Content
