Embodiment Construction

[0006] The invention provides a method for forming an amorphous iron core. First, the amorphous steel strips used as iron core raw materials are grouped and cut according to the calculated size to form a number of iron chips. The lengths of the iron chips are not equal, and then the groups of iron chips are aligned and stacked together, and the clamping tool is used to clamp the middle part of each group of iron chips according to the length of the iron chips, and then the iron chips are bent to form a preliminary docking The ring is extruded inwards in two vertical directions to form an approximately rectangular shape, and then the approximately annular iron core is extruded into a rectangular iron core with four corners arc-shaped through the inner and outer forming splints.

[0007] Several important steps of the present invention are:

[0008] The calculated length of each group of iron chips should be determined according to the length requirements of the position of the ...

Abstract

The present invention relates to an amorphous iron core molding method, first, the amorphous metal strip as iron core material is executed grouping cutting according to calculative dimension, forming several iron chip, and length of the iron chip being equal in same group, length of the iron chip being unequal in different group, then every group iron chip are fold together fitly, using clamping tool clamp the middle part setting location of each iron chip in sequence according to length of iron chip, then iron chip is bent to forming ring shaped of principium butt-joint, and the ring shaped is squeezed at two perpendicular direction to form approximate rectangle, then the sub-circular iron core is squeezed into rectangle iron core with four arc corner by inside and outside molding clamping strap. This kind of method has simple technique, little machining difficulty, and is suit for producing amorphous iron core and especially amorphous iron core of distributing transformer.

Description

technical field [0001] The invention relates to a method for forming an amorphous iron core, which belongs to the technical field of amorphous iron core production. technical background [0002] The production of the existing amorphous iron core is to wind the core steel strip into a seamless rolled iron core with a window (middle hole) in the middle, and then make a part of each layer of the seamless rolled iron core Fixing, cut the iron chips of each layer at the position opposite to the fixed part according to a certain method, and then bend and extrude the cut amorphous iron chips to form a rectangular iron core. The disadvantage of this method is that the process is complicated and the processing is difficult. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for forming an amorphous iron core, which is simple in process and less difficult in processing. [0004] The technica...
