Iron-based amorphous iron core production system and preparation method thereof

Abstract

The invention relates to an iron-based amorphous iron core production system and a preparation method thereof. The system comprises a discharging mechanism, a leveling mechanism, a feeding mechanism,a jet flow cutting device, a waste recycling mechanism, a tunnel type annealing furnace, a forming overlying mechanism, a gum dipping device and a curing oven which are sequentially arranged from leftto right in the conveying direction. A workpiece cleaning device and a first transfer robot are arranged between the jet cutting mechanism and the waste recovery mechanism, and the cleaning device and the first transfer robot are arranged on the two sides of a strip correspondingly; and a second transfer robot is arranged between the tunnel type annealing furnace and the forming overlying mechanism. Continuous production of the iron core is achieved, annealing and forming stacking are conducted in sequence, defective punching sheets can be found earlier, and the defective rate of finished products is reduced.

Description

technical field [0001] The invention belongs to the field of motor preparation, and in particular relates to an iron-based amorphous iron core production system and a preparation method thereof. Background technique [0002] There are currently two manufacturing techniques for motor iron cores. The first is the amorphous block cutting method: first, the amorphous alloy strip (18) of a predetermined width is cut to form an amorphous sheet of a specified length, and the amorphous sheet is superimposed on the specified length. Thickness forms an amorphous block (amorphous rod), and then undergoes a certain annealing process to eliminate internal stress, and finally cuts to form an amorphous core of the size and shape specified in the drawing. The second is the superimposed punching method: select a sheet of appropriate width, cut it into a punched sheet of a specified size and shape by punching, then stack the punched sheet to a specified height, eliminate the internal stress t...

Problems solved by technology

The second is the superimposed punching method: select a sheet of appropriate width, cut it into a punched sheet of a specified size and shape by punching, then stack the punched sheet to a specified height, eliminate the internal stress through the annealing process, and pass through the resin after annealing. The dipping and solidification casting process makes the stacking of the stator punches into a whole to form an amorphous core; the main problem with the first method is that after the amorphous material is superimposed into an amorphous block, the thickness increases greatly, and the amorphous core is easily damaged during cutting. Crystal blocks, resulting in gaps, cracks, etc. on the edge of the cut iron core, and a high reject rate of the product; and the second method, the sheet is first cut into punched pieces, and then the punched pieces are superimposed into the production method of the iron core , although the damage rate in the cutting process is reduced, but because the amorphous nanocrystalline alloy material has the char...
