Cold-rolled tubes have a fine grain structure and superior mechanical and physical properties. After rolling, the finished tubes are continuously discharged. Traditional receiving racks are fixed structures, causing rigid collisions between the tubes and the rack as they fall, which can easily damage the tube surface and affect product quality. Therefore, there is an urgent need for a discharge device that can buffer the material, reduce impact, and protect the tube surface. Utility Model Content
