AI Technical Summary
Existing piston rod polishing processes generate significant dust and noise pollution during the grinding process, impacting worker health.
A three-roll calender is used, including a first, second, and third roller arranged in a triangular pattern. The tapered shoulders of the first and second rollers are used for symmetrical extrusion polishing. Combined with the idler wheel drive principle, the piston rod rotates and moves axially during the polishing process, achieving 360-degree uniform polishing.
It effectively reduces dust and noise pollution, while achieving uniform polishing of the piston rod. The structure is simple and easy to implement.
