Permanent magnet material forming machine

Abstract

The invention relates to the technical field of forming machines, in particular to a permanent magnet material forming machine which comprises a forming mechanism, grinding mechanisms and suction pipes. The grinding mechanisms are fixedly connected to the left side and the right side of the forming mechanism, and symmetrically distributed with the forming mechanism as the center; a driving mechanism is fixedly connected to the center of the outer surface of the lower side of each grinding mechanism; and the suction pipes penetrate through the bottom positions of the grinding mechanisms. A conical prismatic table is arranged in a material crushing box, and therefore particle raw materials are crushed into powder under the action of square sawteeth, and gradually flows to a filter screen I arranged at the bottom of a grinding cavity, and the particle raw materials in and a filter screen II are crushed into powder under the action of the sawteeth and flow to the suction pipes. When a concave rail on the outer surface of the lower end of a radian powder pipe collides with protrusion semicircles II evenly distributed on a baffle, the powder attached to the inner walls of the radian powder pipe and a raw material pipe are slide down, and therefore the attached powder residues are reduced; and the product quality and the working efficiency of the device are finally improved through cooperation of a groove and a radian shift lever.

Description

technical field [0001] The invention relates to the technical field of forming machines, in particular to a permanent magnet material forming machine. Background technique [0002] Permanent magnet materials, also known as "hard magnetic materials", refer to materials that can maintain constant magnetic properties once magnetized. In practical applications, permanent magnet materials work in the second quadrant demagnetization part of the hysteresis loop after deep magnetic saturation and magnetization. Commonly used permanent magnet materials are divided into AlNiCo permanent magnet alloys, FeCrCo permanent magnet alloys, permanent ferrites, rare earth permanent magnet materials and composite permanent magnet materials. As an ancient and young basic functional material with a wide range of uses, its application has penetrated into all aspects of the national economy and national defense in the long-term development process. The magnetic material itself has also been greatl...

Problems solved by technology

[0005] This kind of sintered NdFeB permanent magnet material tablet molding machine also has the following defects in the specific use process: 1. Especially for installing crushed balls in the crushed material box, it is in the process of crushing the particles , there will be a lot of granular raw materials splashing out the crushed balls while falling, resulting in low grinding efficiency. The granular raw materials will enter the crushed material box through the suction pipe for many times to work, increasing the load on the motor and the crushed balls , to reduce its life; 2. At the same time, for the raw material buffer box, raw material tube and arc powder tube, in the process of separating the powder from the raw material after screening, there will be a lot of powder attached to the raw material buffer box, raw material tube and arc powder tube The inner wall of the powder tube cannot be cleaned, and is affected by the external humid environment. Over time, more and more powder will adhere, resulting in the smaller space available for the raw material buffer box and lower use efficiency; 3. And when the powder passes through When the slope of the baffle falls on the mold seat, most of the powder will gather in the middle of the mold seat and be distributed in the shape of a valley due to the inclined sliding of the powder. , the thick tablet in the middle, resulting in uneven density of the formed tablet, affecting product quality
