Quality management method for transformer core processing

Operators conduct self-inspection and mutual inspection of the parts they process. During the self-inspection and mutual inspection process, if problems are found and corrected, they will be exempted from punishment. Before being transferred to the next process, they must be inspected by a full-time quality inspector, and they can be transferred to the next process only after they are qualified. If there are quality problems, the operator will be punished according to the specific situation, and the full-time quality inspector will be exempted from punishment; if the quality problems are missed or not detected, the full-time quality inspector and the operator will be punished once they are found, and the person who found the problem will be rewarded. The no-load loss of the core does not exceed the design value.

Method for ensuring no-load loss Wuxi transformer core, the production technology department reasonably selects silicon steel sheets according to the sales contract and the core diameter requirements. It leaves a reasonable technical coefficient for shearing and laminating. If the shearing and laminating technology is normal, the no-load loss error is more than ±3%, check the design personnel. After the iron core processing workshop gets the calculation drawings, it 1st checks the drawings to see if they meet the technical coefficients. If there are any questions, it will communicate with the technical department in time for timely adjustment. If there is no communication, the work time caused by the rework will be borne by the workshop itself.

In the transformer iron core processing quality management method, the shearing workshop should select and process the silicon steel sheets before shearing (curling, curling, rust), and unqualified silicon steel sheets with creases are not required. Rough operation is prohibited during operation (excessive bending and collision of silicon steel sheets). If a rough operation is found, it will be handled according to the quality management reward and punishment method. Suppose there are new defects caused by rough operation. In that case, the operator will compensate the company for the loss, and the team that cannot find the responsible person will be responsible. Pay attention to the rolling direction of the silicon steel sheet when shearing the sheet material, and the length direction of the sheared sheet should be consistent with the rolling direction.
