Abstract

The invention discloses a double-end rapid forming machine of anisotropic ferrite magnetic shoes. The double-end rapid forming machine comprises a rack, a transmission mechanism, an automatic feedingmechanism, an upper press mechanism, a lower sliding column mechanism, a mold frame mechanism and a push mold mechanism. The mold frame mechanism comprises a symmetrically-arranged double mold end structure. A pre-pressing mechanism used for reducing the descending speed of an upper mold plate is further included. Through coordinative cooperation of the upper press mechanism, the mold frame mechanism and the lower sliding column mechanism, two magnetic shoes can be pressed at a time, and the work efficiency can be improved by about 80%. The invention further discloses a forming method of the magnetic shoes. The forming method comprises the steps of powder filling, magnetic field orientation, pressing, demagnetizing and demoliding which are connected successively. The method further comprises the step of pre-pressing, and the step of pre-pressing is carried out after the step of magnetic field orientation is started till the step of magnetic field orientation is finished. The quality and performance of the magnetic shoes manufactured through the double-end forming technology both reach the criterion of acceptability, and the quality is equivalent to that of magnetic shoes manufactured through the single-end forming technology.

Description

technical field [0001] The invention relates to the technical field of magnetic tile manufacturing, in particular to a double-head rapid prototyping machine and a molding method for heterosexual ferrite magnetic tiles. Background technique [0002] In the existing magnetic tile dry forming technology, single-head rapid prototyping is mostly used to obtain better product quality and performance. In terms of improving efficiency, it is limited by the pressing time of the press and the orientation time of the magnetic field, so it is difficult to improve the efficiency. One-mode multi-watt technology can effectively improve production efficiency, but the application of this technology forms technical obstacles in the uniformity of multi-cavity powder filling and mutual interference of magnetic field orientation, making the quality and performance of the produced products fail to meet the qualified standards . Aiming at the above-mentioned technical difficulties, the inventor ...
