        Metal Spinning Forming Technology

        發表于 2020-07-22

        What is spinning forming technology

        Metal Spinning Forming Technology is to press the metal tube blank, flat blank or preform with the tail top onto the spinning core mold, and the spindle drives the mandrel and the blank to rotate, and at the same time, the spinning wheel starts from the blank. The side squeezes the material on the rotating core mold to cause the material to produce point-by-point continuous plastic deformation, so as to obtain hollow rotating parts with various generatrix shapes.

        Spinning is an advanced manufacturing process without cutting processing that integrates forging, extrusion, deep drawing, bending, and rolling.

        Features of spinning forming

        (1) Spinning belongs to local continuous processing, the instantaneous deformation zone is small, the total deformation force required is small, the processing equipment requirements are simple, and the mold cost is low;

        (2) Most of the deformation zone is in a state of compressive stress, giving full play to the deformation ability of the material, and it is easy to process parts with complex shapes or parts with high-strength and difficult-to-deform materials;

        (3) Spinning is a cutting process with little and no cutting, with high material utilization.

        Metal Spinning

        The development history of spinning

        Spinning equipment originated from the ceramic blank making operations during the Yin and Shang era in my country. In the early 10th century, my country had ordinary spinning equipment and began to make thin metal plates into hollow rotating parts. In the 13th century, spinning technology spread from my country to European countries. Around 1840, spinning technology spread from Jordan to the United States. In the late 1860s, the first patent for metal spinning equipment appeared in Germany.

        In the middle of the 20th century, two key breakthroughs occurred in spinning equipment: the first was the realization of mechanization and automation of ordinary spinning equipment; the second was in the late 1960s, the West German Leifeld company successfully developed the use of NC or CNC numerical control system and the spinning machine of PNC system realizes automation.

        After nearly 60 years of development, foreign metal spinning technology has become increasingly mature, and this technology has been widely used in a foreign military or civilian industries. The United States, Germany, Spain, etc. all have world-class spinning technology. The spinning machines in these countries have achieved specialization, serialization, stable performance, and convenient operation. There are multiple forms such as single-wheel, double-wheel, and three-wheel.

        Spinning application

        The materials that can be used for spinning forming include aluminum alloys, magnesium alloys, titanium alloys, copper alloys, low-carbon steels, high-temperature alloys, maraging steels, high-strength steels, ultra-high-strength steels, and stainless steels.

        Spinning technology has been widely used in aerospace, aviation, military, automotive, chemical, electronics, and other fields.
