Furthermore, a pressure plate for clamping the iron core is installed at the top end of the C-shaped positioning plate.

Furthermore, pin holes are formed in the central frame of the upper bottom plate and the lower bottom plate in a shape like Chinese character' ri

Further, the baffle is an iron plate with the thickness of 10 mm.

Further, the core penetrating holes are formed in the inner sides of the four corners of the bottom plate.

The utility model discloses the beneficial effect who reaches does: 1. this lamination frock is equipped with the location nail at each cross core hole, makes iron core fix on the primary importance all around, and each post has baffle fixed position. 2. And secondly, the lamination tool is provided with positioning at the position needing to be structured, so that the arrangement and shaping in the iron core lamination process are reduced. 3. The original lamination process is replaced and replaced by the improvement of the invention, the uniformity and the performance of the iron core are solved, the laminated iron core can be produced in a large scale, the iron core on the die is fixed by painting, the noise pollution during iron core arrangement is reduced, the performance of the dry-type transformer is better optimized, partial labor is saved, and the efficiency is improved.
