[0029] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] Working principle: Wind multiple iron core strip materials onto each unwinding wheel 14 in sequence, and make each iron core strip material pass through its corresponding tension guide wheel 15, then through each collecting wheel 23, then through the first guide wheel 26 and the bump 25 to collect the iron core strip materials, so that multiple iron core strip materials form a core column. Make the core column pass through the inside of the trimming box 33 and between two second guide wheels 39 on the limiting plate 38, and finally fix it to the iron core frame 43. The winding motor 42 drives the iron core frame 43 to rotate, and then performs the winding work on the core column;

[0031] Furthermore, when the core column passes through the trimming assembly 3, the punching and shearing motor 345 drives the main driving wheel 342 to rotate. Under the transmission of the belt 344, the main driving wheel 342 will make the belt 344 drive the driven driving wheel 343 to rotate. The driven driving wheel 343 drives the turntable 346 to rotate, and the turntable 346 drives the eccentric rod 347 to perform an eccentric motion. Furthermore, the lower end of the eccentric rod 347 drives the trimming upper die 36 to move up and down, so that the trimming upper die 36 completes the punching and shearing work on the core column, and cuts off the redundant circular part of the core column. When the winding motor 42 drives the iron core frame 43 to rotate half a circle, the core column is punched and sheared once. At the same time, make the trimming box 33 slide on the second slideway 32, and the unwinding rack 13 slide on the first slideway 12 to make it in a straight line at four points, which can improve the cross-section of the upper and lower yokes, reduce the loss of the transformer, and improve the production efficiency.
