An aluminum strip shearing unit for a transformer

Abstract

The invention discloses an aluminum strip shearing unit for a transformer. The aluminum strip shearing unit comprises a unit main machine, an uncoiler, an upper gap bridge device, a shearing mechanism, a recoiling machine and an interleaving paper clamping device. The uncoiler is used for bearing material rolls to be processed; the upper gap bridge device comprises an entrance guide roller and a plurality of guide rollers, and the material rolls to be processed enter the upper gap bridge device from the entrance guide roller; the shearing mechanism is arranged in the middle of the unit main machine, a traction roller is arranged above the shearing mechanism, and the traction roller presses and sends the material rolls to be processed entering the guide rollers to the shearing mechanism; the recoiling machine is arranged on one side of the shearing mechanism and used for receiving the material rolls sheared through the shearing mechanism; the interleaving paper clamping device is adjacent to the recoiling machine, the interleaving paper clamping device conveys insulation paper into the recoiling machine, and the recoiling machine and the interleaving paper clamping device work simultaneously so that the insulation paper can be clamped among the sheared material rolls. The aluminum strip shearing unit effectively solves the problems of the finished-product roll side face burr removal and surface protection, and the product quality and production efficiency are improved.

Description

technical field [0001] The invention belongs to the field of aluminum strip foil shearing units, in particular to an aluminum strip shearing unit for transformers. Background technique [0002] In the prior art, the thickness of the aluminum strip used for transformers is in the range of 0.5-3.0 mm, and the slitting and slitting are basically completed on the aluminum strip slitting machine. The tension station of the slitting machine has uneven tension in the width direction of the aluminum strip, which will cause The surface of the aluminum strip after slitting is severely scratched, and the structure of the separator before single coiling will damage the two sides of the finished coiled aluminum strip. These defects are the same as the smooth surface of the transformer aluminum strip, and there are no burrs, curls and side bends on the side. The technical indicators do not meet the requirements, the scrap rate is high, and the process requirements of slitting, end chamfer...

[0002] In the prior art, the thickness of the aluminum strip used for transformers is in the range of 0.5-3.0 mm, and the slitting and slitting are basically completed on the aluminum strip slitting machine. The tension station of the slitting machine has uneven tension in the width direction of the aluminum strip, which will cause The surface of the aluminum strip after slitting is severely scratched, and the structure of the separator before single coiling will damage the two sides of the finished coiled aluminum strip. These defects are the same as the smooth surface of the transformer aluminum strip, and there are no burrs, curls and side bends on the side. The technical indicators do not meet the requirements, the scrap rate is high, and the process requirements of slitting, end chamfering, and lining paper cannot be completed on one piece of equipment, and the production efficiency is low
