Problems solved by technology

For such an iron core, after annealing to remove the warpage of the iron core in the subsequent process, the iron core disintegrates together, and it is difficult to return to the original shape of the iron core when it is assembled with the coil winding. It requires a lot of force to restore it, and it is difficult to work manually. In addition, when the tension is applied, the steel belt is sometimes pulled, causing the offset of the overlapping position and making defective products.
On the other hand, relative to the winding-in speed of the steel strip, when the feeding speed of the steel strip is fast, the steel strip slacks, causing bending or cutting length errors of the steel strip, scratches on the side of the iron core or large or small overlaps, reducing quality

Abstract

The invention relates to a winding core manufacturing device, comprising: coiling device (22) for winding the metal strip (SS) between winding frame (10) and coiling strips (13) to wind the winding core (23); metal strip supplying machine (29) for sending the metal strip to supply roller (25); clipper (40) installed between the coiling device and metal strip supplying machine and cutting the metal strip without stopping it. The metal strip supplying machine is controlled to send metal strip at the speed equal to coiling speed of metal strip of the coiling device. When the metal strip supplying machine supples the metal strip of preset length, the said metal strip is cut by clipper for unit metal strip to continuously wind the winding core. The cut length is calculated based on the thickness of metal strip calculated by strip length of each revolution of the winding frame. Therefore, the invention can produce a number of iron core of high quality with proper clearance between each butt-joint part or lapping amount.

Description

technical field [0001] The present invention relates to a wound core manufacturing apparatus for manufacturing a wound core by winding a steel strip between a winding frame and a winding belt to wind a steel strip around a winding frame. Background technique [0002] The wound core has the following structure: the unit steel strip is wound into one turn and the two ends are lapped (overlapped) with a specified lap amount (ラツプデ) or the lap is zeroed (突き合わせ) to form multiple layers. A plurality of laminated structures of laminated core blocks. [0003] Figure 15 An example of a wound core structure formed in a circular shape is shown. In this core, three core blocks B1 to B3 are provided. The three core blocks are formed so that the junctions (overlapping parts or butt joint parts) of both ends of the respective unit steel strips are formed. )J is distributed in a step-like state within approximately the same range. [0004] When manufacturing a wound core, a winding frame ...
