Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 3 to 6, the utility model provides a lamination tool for iron cores of transformer products, which is suitable for the lamination of large and medium-sized electronic transformer iron cores and comprises a channel steel 3 and a square tube device 4; 2 levels of iron core are placed and are piled up on channel-

section steel

3, 2 one ends plug-in connection a plurality of yokes 1 of iron core that pile up, 2 other ends of iron core that pile up lock through square pipe device 4.

The square tube device comprises an upper tube 41 and a lower tube 42, the upper tube 41 and the lower tube 42 are parallel to each other, preformed holes are formed in the upper tube 41 and the lower tube 42, and the preformed holes of the upper tube 41 and the lower tube 42 are connected through bolts and nuts in a matched mode to achieve locking and unlocking functions.
