Description

Technical Field

[0001] The utility model relates to the field of transformer iron core production, in particular to a coiling and leveling machine for producing transformer iron cores. Background Art

[0002] To process transformer core sheets, you need to purchase silicon steel sheets, which are then stamped into pre-designed transformer core sheets. After curling, the silicon steel sheets undergo a certain degree of deformation, causing the newly unfolded ring-shaped silicon steel sheets to have a certain curvature. If stamping is performed immediately, the precision of the parts will decrease. In order to improve the precision of the parts, hardware processing factories usually use leveling machines to flatten the silicon steel sheets with curvature multiple times, making the silicon steel sheets smoother.

[0003] After searching, the Chinese patent announcement number CN219105915U is found, which discloses a coil leveling machine for producing transformer cores. The patent, through the composition of a motor, a slide plate, a connecting plate, a bidirectional threaded rod, an anti-bias plate and other structures, realizes the use of the anti-bias plate to squeeze the core to the middle and align it, thereby preventing the core from shifting during the leveling process, thereby not affecting the leveling effect. Through the composition of a fixed plate, a roller brush and other structures, the core can be cleaned during the leveling process, thereby eliminating the need for manual cleaning, thereby saving labor costs, and at the same time, there is no need to use a separate cleaning equipment, thereby reducing production costs.

[0004] However, when the above patent uses two roller brushes to clean impurities on the surface of the coil, as the coil is continuously conveyed, more and more impurities accumulate near the roller brushes, which may affect the cleaning effect. Utility Model Content
