NdFeB large parts chamfering equipment

Abstract

The invention discloses a chamfering device for a neodymium-iron-boron large part. The chamfering device comprises a groove body, a water purifier and a controller; the top part of the groove body isprovided with an opening, multiple vertically staggered partition plates are arranged in the opening, the edges, adjacent to the inner wall of the groove body, of the of the partition plates abut against the inner wall of the groove body, and multiple sand guide holes are formed in the partition plates at intervals; the bottom part of the groove body is arranged on a vibrating table driven by a first frequency modulation motor; the water purifier is internally provided with a filter element, a water inlet of the water purifier communicates with the lower part of the groove body through a waterinlet pipe, a water outlet of the water purifier communicates with the upper part of the groove body through a water outlet pipe, and the water outlet pipe is provided with a micro water pump; and the controller is arranged outside the groove body, the controller is electrically connected to the first frequency modulation motor and the micro water pump, and a PLC control module is arranged in thecontroller. According to the chamfering device, mutual collision in the chamfering process of the neodymium-iron-boron large part can be avoided, and the product chamfering quality is improved.

Description

technical field [0001] The invention relates to the field of NdFeB chamfering electroplating. More specifically, the present invention relates to a chamfering equipment for NdFeB large parts. Background technique [0002] For NdFeB material, its chemical properties are active and the edges of its processed products are sharp. In order to use the product better, it is necessary to electroplate a protective film such as zinc or nickel on its surface. In order to overcome the edge effect during the electroplating process and reduce the edge The problem of poor coating, and to prevent sharp edges and bumps, so it is necessary to perform chamfering before electroplating. The function of chamfering is to make the edges of NdFeB products smooth, so that zinc or nickel layers can be better electroplated on the edges of products. And not easy to bump. At present, most of the chamfering in the industry is 1. Single tank chamfering machine, and multiple large parts are chamfered toge...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. Multiple large parts are poured into a single tank, and the large parts will collide with each other during the chamfering process, which will damage the workpiece and affect the quality of the chamfering of the product; 2. The material of NdFeB is hard, and the chamfering sand If the direct mechanical collision force is too large, it will cause the edge of the product to bump and collapse, and damage the substrate, and for such a lively material as NdFeB, the product is easily oxidized and corroded when exposed to humid air, and its It is also quite sensitive to the adsorption of various impurities during the chamfering process; 3. During the chamfering process, manually adjusting the frequency will increase the workload of workers and reduce production efficiency
