Automatic shearing and polishing device for annular neodymium-iron-boron magnet

Abstract

The invention discloses an automatic shearing and polishing device for an annular neodymium-iron-boron magnet. The automatic shearing and polishing device for the annular neodymium-iron-boron magnet comprises a cabinet body, a conveying device, a primary grinding device, a movable conveying device, a shearing device and a fine grinding device, and the conveying device penetrates through one side of the cabinet body; the primary grinding device is arranged at the upper end in the cabinet body; one side of the primary grinding device is connected with the movable conveying device; the shearing device is arranged under the movable conveying device, one side of the shearing device is connected to the left side wall of the cabinet body through a supporting column, and the other side of the shearing device is fixedly connected with the right side wall of the cabinet body through a fixing frame; the fine grinding device is arranged below the shearing device and penetrates through the other side face of the cabinet body through a third conveying belt; and a first motor is further arranged on the right side wall in the cabinet body, and the first motor is connected with the movable conveying device and the fine grinding device through a belt. Raw materials do not need to be carried manually, rapid, efficient and automatic machining of the neodymium-iron-boron magnet is achieved throughcooperation of mechanical shearing and two-time grinding processes, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of NdFeB processing, in particular to an automatic shearing and grinding device for an annular NdFeB magnet. 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 materials are alloys of praseodymium neodymium metal, boron iron and so on. Also known as magnetic steel. NdFeB has extremely high magnetic energy product and coercive force, and the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology, so that instruments and meters, electroacoustic motors, magnetic separation and magnetization Miniaturization, light weight, and thinning of equipment such as equipment become possible. [0003] Due to the small size of the small magnetic ring, it is difficult to open the...

AI Technical Summary

Problems solved by technology

During the processing of NdFeB ring structure after drilling, transshipment and shearing are required. In order to improve efficiency, feeding and shearing devices are usually used to replace manual handling and cutting. However, the existing feeding devices are used in the process of feeding magnets Among them, the stability is poor, it is prone to failure, and the processing link is difficult to realize automatic transportation, and manual assistance is still required for frequent interruptions. In addition, some special feeding devices are expensive, which affects production; in the cutting process, there are clamping devices that are complicated and easy. Damage to the blank, low slicing efficiency and difficulty in continuous operation, etc.

[0004] In addition, during the processing of NdFeB magnet blanks, the surface of the magnet needs to be processed to meet the needs of customers or equipment, that is, the external dimensions of the magnet need to be ground. The blank is manually transferred to the feeding port of the grinding machine, and the production efficiency is low; the staff often need to manually move the processing station to rotate the material to be polished, which is easy to be injured; it is difficult to guarantee the processing accuracy after only one grinding, which affects the product quality
