Abstract

The invention relates to the technical field of NdFeB production equipment, in particular to an interface structure for an NdFeB storage tank. It includes a barrel mouth arranged on the barrel body, the opening end of the barrel mouth is constructed with a stepped connection part, and the outer side of the connection part is threaded with a fastening ring; the connection part is provided with a gap in the axial direction, and the fastening ring is placed There is a ejector rod in the gap; the internal structure of the fastening ring has an accommodation chamber for placing the ejector rod, the inner wall of the fastening ring is provided with a telescopic opening connected with the accommodation chamber, and the ejector rod is telescopically constructed in the accommodation chamber from the telescopic opening; The side wall of the cavity opposite to the expansion port is provided with a top rail in the circumferential direction. The gap between the top rail and the expansion port gradually becomes smaller in the direction of rotation of the fastening ring. The top rail is used to follow the rotation of the fastening ring to change the diameter of the ejector rod. up position. Through the present invention, the NdFeB storage barrel can be preferably fixedly connected to the corresponding discharge port.

Description

technical field

[0001] The invention relates to the technical field of NdFeB production equipment, in particular to an interface structure for an NdFeB storage barrel. Background technique

[0002] NdFeB magnetic material, as the latest result of the development of rare earth permanent magnet materials, is called "Magnetic King" because of its excellent magnetic properties. NdFeB magnetic material is an alloy of praseodymium neodymium metal, boron iron, etc., also known as magnetic steel. NdFeB has extremely high magnetic energy product, coercive force and energy density. It has been widely used in modern industry and electronic technology, making instruments and meters, electroacoustic motors, magnetic separation and magnetization equipment miniaturized, lightweight, Thinning is possible.

[0003] NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. The advantages of NdFeB are high cost performance ...
