[0002] Due to their unique structure and excellent performance, bellows are widely used in many fields, particularly where flexible connections and compensation for pipe displacement are required. To ensure the quality of bellows, tensile testing is often required. Existing bellows tensile dies typically consist of a main frame, guides, and fixtures. The basic function of these dies is to secure the bellows in a predetermined position and then test its performance using tensile forces.
