[0002] With the development of marketization, product quality is undoubtedly a powerful weapon to improve corporate competitiveness and customer satisfaction in the fiercely competitive market. Because there is no special tool for managing and storing the press-fitting pads of the transformer body in the existing technology, the operator cannot well grasp the actual number and usage of the press-fitting pads. When the transformer body is pressed out of the furnace, once the press-fitting pads fall into the body, it will cause discharge during the partial discharge test of the transformer, generating gases such as acetylene and ethylene, which poses a serious quality risk. Summary of the invention

[0003] The purpose of the present invention is to provide a visual storage management method and storage box for transformer body press-fitting pad tooling, which can not only accurately check the number of press-fitting pads and avoid the risk of press-fitting pads falling inside the transformer body, but also facilitate operators to accurately find press-fitting pads of corresponding specifications, thereby improving work efficiency and solving the above-mentioned problems existing in the background technology.

[0005] Furthermore, the press-fitted pads are differentiated by material into blackened carbon structural steel plates, epoxy glass cloth plates and stainless steel plates, and the interior of the storage box body is divided into three large partitions by partitions. The first large partition is divided into two small partitions by partitions, and epoxy glass cloth plates of different thicknesses are placed in the two small partitions; the second large partition is placed in a blackened Q235B plate; the third large partition is divided into two small partitions by a partition, and comb plates are welded on both side walls of the two small partitions, and S30408 ​​plates of different thicknesses are placed in the two small partitions.

[0006] A transformer body press-fitted pad tooling storage box comprises a storage box body, wherein the storage box body is a rectangular box body welded together by a left side plate, a right side plate, a front panel, a rear panel and a bottom plate, wherein a plurality of large partitions A are divided into the storage box body by horizontal partitions, a plurality of vertical partitions are installed in the plurality of large partitions A, and the large partitions A are divided into a plurality of small partitions B, and two comb plates are respectively welded on the side walls of the plurality of large partitions A and the small partitions B.

[0007] Furthermore, the transverse partition includes an intermediate baffle and an upper panel. There are two intermediate baffles, which are welded in parallel at the middle of the storage box body, and the upper panel is welded between the upper end surfaces of the two intermediate baffles.

[0008] The innovative features of the present invention are as follows: 1. Optimize the selection of materials for the pad tooling and reasonably design the storage box structure. During the press-fitting process, use boiled black, stainless steel, and glass cloth materials to press the pads to prevent dirt and impurities from falling on the body of the device, ensure the cleanliness of the body, and improve the product test pass rate. Complete the accurate record of the number of press-fit pads, thereby effectively avoiding the risk of the press-fit pads "falling" inside the body. The chamfers of the storage box are polished and smooth, and the connection positions are fully welded.

[0009] 2. Improved work efficiency and safety. During the press-fitting process of the device body, press-fitting pads of the same size are neatly arranged, which improves the efficiency of the operator in finding and placing the press-fitting pads. At the same time, during the press-fitting process of the device body, press-fitting pads of the same size are prevented from bursting out, ensuring personal safety. After the press-fitting is completed, the operator can quickly and accurately verify the number of press-fitting pads, and the missing number can be clearly seen at a glance, which significantly improves work efficiency. The press-fitting pads have been used in more than 10 projects in a certain region. Each product is expected to save 30 minutes, improve the efficiency of the entire process by 40%, and shorten the press-fitting time.

[0010] 3. Improvement of 6S on-site management. There are many types and quantities of press-fitting pads. The press-fitting pads and tooling are made in a unified manner, which greatly improves on-site management and work efficiency.

[0011] Positive effects of the present invention: The present invention realizes accurate recording of the number of press-fitted pads and improves work efficiency by carrying out traceable and visual management of the press-fitted pads, thereby greatly reducing the probability of leaving the press-fitted pads inside the device body, until it is completely avoided, thereby avoiding quality risks in the transformer, improving product quality, and providing permanent benefits with a one-time investment. There are many types and quantities of press-fitted pads, and the press-fitted pads and storage boxes are manufactured in a unified manner, which greatly improves on-site management and work efficiency. After the press-fitting is completed, the operator can quickly and accurately verify the number of press-fitted pads, and the missing number can be clearly seen at a glance, which significantly improves work efficiency.
