a. Flare and form one end of the rivet. The flared thickness should be 2.3-3 mm, with a diameter of Φ13.5-14 mm. b. Place the processed silicon steel sheets onto the dedicated fixture for stacking. Trim the core laminations during the stacking process, ensure they are perpendicular to the base plane, and prevent any eccentricity. c. After the core stacking is complete and clamped tightly with a pressure plate, measure the stacking thickness to ensure it meets the drawing requirements. d. Fit the rivets with washers, insulating spacers, and insulating sleeves, then flare and form them. Ensure that the tightness of all installed rivets is consistent. Read More

Operators must conduct self-inspections and cross-inspections on the parts they process. During the self-inspection and cross-inspection process, if problems are identified and corrected, no penalties will be imposed. However, before transferring to the next process, the parts must be inspected by a full-time quality inspector and can only proceed if they pass. If quality issues are found at this stage, the operator will be penalized based on the specific situation, while the full-time quality inspector will be exempt from penalty. If quality issues are discovered later due to missed inspections or failure to detect them, both the full-time quality inspector and the operator will be penalized once discovered, and the person who identifies the issue will be rewarded. The no-load loss of the transformer core must not exceed the specified design value. Read More
