Description

Technical Field

[0001] This invention relates to the field of ultrasonic rolling technology, specifically to ultrasonic rolling processing equipment for surface treatment of ultra-long small-diameter pipes. Background Technology

[0002] Ultrasonic rolling is a process that combines ultrasonic impact energy with static rolling to strengthen the surface of parts. It can effectively reduce surface roughness, introduce residual compressive stress, and improve the corrosion resistance, wear resistance, and fatigue resistance of parts. For pipes, existing ultrasonic rolling equipment uses a method where both ends of the pipe are clamped and rotated by a clamping mechanism, and then a conveying mechanism drives the clamping mechanism to move linearly, simultaneously achieving the rotation and linear movement of the pipe. An ultrasonic rolling mechanism is placed on one side of the pipe to perform surface treatment on the moving pipe. This type of ultrasonic rolling equipment has the following drawbacks: Firstly, the clamping... The holding mechanism needs to have both rotation and clamping functions, making it relatively complex and resulting in high costs and inconvenient maintenance and debugging. Secondly, the conveying mechanism needs to have a long stroke to meet the feeding requirements; however, a long stroke mechanism leads to a large overall footprint of the equipment. Thirdly, for the ultrasonic rolling tool head, due to the rigid collision between the balls and the ball sleeve, the tool head mechanism will wear out after a certain period of use, resulting in a short service life. Furthermore, the main body shell of the tool head and the ball sleeve are often designed as a single piece, requiring the replacement of the entire shell during maintenance, which increases maintenance costs.
