Beschreibung
Zusammenfassung:	The invention provides a butterfly-shaped end socket punching and spinning forming technology, and relates to the technical field of end socket forming, the butterfly-shaped end socket punching and spinning forming technology comprises the following steps: S1, material selection: selecting a high-strength large-specification steel billet material, and the tensile strength of the steel billet material is greater than or equal to 880 MPa; according to the butterfly-shaped seal head, the butterfly-shaped seal head is divided into three parts, namely the top circular plate, the arc-shaped petal piece and the circular-ring-shaped petal piece, batch punch forming is conducted on the top circular plate, the arc-shaped petal piece and the circular-ring-shaped petal piece are formed in a spinning mode, finally, the top circular plate, the arc-shaped petal piece and the circular-ring-shaped petal piece are welded and assembled, and through assembly line machining operation, the production efficiency is improved.
