Description

Technical Field

[0001] The invention relates to a manufacturing device and a manufacturing method for a motor iron core. Background Art

[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 future motors. This puts higher requirements on the electromagnetic performance of the stator core. High-performance motors require the motor iron loss to be as small as possible (in order to reduce motor heating), so it is hoped that the core sheet is as thin as possible (to effectively reduce the eddy current loss of the core sheet) or a new core material is used. Core sheets are usually made of silicon steel sheets (silicon steel sheets) or non-chip sheets (hereinafter referred to as sheets). For sheets with a thickness greater than 0.2mm, high-speed punching can be easily achieved, while the processing of sheets with a thickness less than 0.2mm, especially ultra-thin strips, such as iron-based ultra-thin sheets (0.01-0.15mm), has become a major problem in achieving industrial production. In addition to being "thin", ultra-thin sheets are also "hard" and "brittle". Due to the special production process, the iron-based ultra-thin sheets have poor machinability (for example, the hardness is increased by 5-6 times). At the same time, because the ultra-thin sheets are too thin, they are not easy to cut directly, and the cutting efficiency is low. First, it is difficult to mass produce. Secondly, the high-efficiency motors made of ultra-thin sheets are expensive and cannot be promoted on a large scale. If direct punching is used, the processing accuracy of the mold is very high and difficult to achieve. It will also cause large burrs, tearing, unbroken, bending and other phenomena, making batch stamping impossible. The requirements for the punch press accuracy, feeding and fixing mechanism, mold matching accuracy, mold material, etc. are very high. The equipment is extremely difficult to implement, and the cost of equipment and iron core production is high, so it cannot be applied on a large scale. Summary of the invention

[0083] Embodiment 2: A 0.5 mm thick laminated plate 200 is formed by laminating an iron-based ultra-thin sheet of amorphous or nanocrystalline strip material with a thickness of 0.025±0.005 mm to produce a motor core.

[0084] A normal 0.5mm non-oriented silicon steel sheet punching machine is used, and the matching mold accuracy and the matching punching gap between the upper and lower molds are set according to needs. Among them, the upper mold 72 has a special glue dispensing mechanism for gluing and laminating between the layers.

[0085] Step 1: Select 4 rolls of 0.025mm thick ultra-thin strip 100, each roll is wound by 5 layers of ultra-thin strip 100, place the ultra-thin strip 100 rolls on the unwinding mechanism 1, pull out the strip head, and pass 20 layers of ultra-thin strip 100 through the dividing roller frame of the dividing mechanism 2 respectively, so that the ultra-thin strip 100 is evenly and regularly divided into 20 layers parallel to each other;

[0087] Step 3: The preliminary laminated sheet is passed through a laminating roller pressing mechanism 5 with a certain pressure, so that each layer of ultra-thin strips 100 of the preliminary laminated sheet is more closely attached together, and preliminary bonding is achieved to obtain a bonded sheet; the laminating roller pressing mechanism 5 has a limiting mechanism for limiting the position of the preliminary laminated sheet, so that both sides of the laminated sheet 200 are neatly arranged;

[0100] Step 4: Continue to feed the bonded sheet into the drying tunnel 6, keep the bonded sheet in a certain temperature atmosphere of 300°C for 1 minute, until the adhesive in the bonded sheet is completely dried, and obtain the laminated sheet 200;

[0101] Step 5: Pass the dried laminated sheet 200 through the cooling air duct 8 to cool the laminated sheet 200, and then pass the online thickness measuring device 9 to obtain the thickness data of the laminated sheet 200, and send the qualified laminated sheet 200 to the next process or be rolled up for standby;
