Abstract

The invention relates to the technical field of NdFeB production equipment, in particular to a pneumatic type sealing gasket. The pneumatic type sealing gasket comprises an outer rubber ring and an inner rubber ring arranged concentrically, wherein the outer rubber ring and the inner rubber ring are connected into a whole through at least two connecting pipes evenly distributed in the peripheral direction; the inside of the outer rubber ring is hollow to form an annular air storage cavity; the inside of the inner rubber ring is hollow to form an annular air collecting cavity; an air runner used for communicating the air storage cavity with the air collecting cavity is formed in the middle of any connecting pipe. The pneumatic type sealing gasket is easy and convenient to use and capable of achieving good sealing performance.

Description

technical field

[0001] The invention relates to the technical field of NdFeB production equipment, in particular to a pneumatic sealing gasket. 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 and good mechanical prop...
