Problems solved by technology

In addition to being "thin", the ultra-thin sheet also has the characteristics of "hard" and "brittle". Due to the special production process, the iron-based ultra-thin sheet has poor processability (for example, the hardness is increased by 5-6 times), and because the ultra-thin sheet Too thin makes it difficult to cut directly and the cutting efficiency is low. Firstly, it is difficult to mass produce. Secondly, the high-efficiency motor made of ultra-thin sheet is expensive and cannot be widely promoted. If the direct punching method is used, the processing accuracy of the mold is very high, and it is difficult Realization will also cause large burrs, tearing, unbroken, bending and other phenomena, so that batch stamping cannot be realized. The requirements for punch precision, feeding fixing mechanism, mold matching precision, mold material, etc. are very high, and the equipment is extremely difficult to realize. , the cost of equipment and iron core production is high, and it cannot be applied on a large scale

Abstract

The invention discloses motor core manufacturing equipment and manufacturing method. The motor core manufacturing equipment comprises a laminated plate laminating device used for laminating at least two layers of ultrathin strips into a laminated plate, a cutting device used for cutting the laminated plate to obtain plate sheets, and a dispensing mechanism used for spraying glue on the surfaces ofthe plate sheets to bond the adjacent plate sheets together. According to the motor core manufacturing equipment, ultrathin strips can be compounded into a laminated plate, the laminated plate can becut through the cutting device, the cutting efficiency is improved, and the requirement for the cutting device due to the fact that the to-be-cut sheets are too thin is lowered.

Description

technical field [0001] The invention relates to a manufacturing equipment and a manufacturing method of a motor iron core. Background technique [0002] The stator core of the motor is the heart of the motor. Miniaturization, high efficiency, high power density, high frequency and high speed are the development trends of the future motor, which puts forward higher requirements for the electromagnetic performance of the stator core, and high-performance motors require The smaller the iron loss of the motor, the better (in order to reduce the heating of the motor), so it is hoped that the thinner the iron chip, the better (it can effectively reduce the eddy current loss of the iron chip) or use a new core material. The iron chip is usually made of silicon steel sheet (silicon steel sheet) or non-wafer (hereinafter collectively referred to as sheet). For sheets with a thickness greater than 0.2mm, high-speed punching can be easily achieved, and sheets with a thickness of less t...
