Quality assurance in the production of dry battery shrapnel

The appearance quality and internal quality of stamping parts are determined by the raw materials. The stamping production of dry battery shrapnel must be fully considered from the mold, plate, process documents, production preparation, operation, storage and feedback processing to ensure high-quality stamping production. Improving the market competitiveness of stamping lays a critical foundation. Mold: Mold is an important process equipment for stamping production, and its quality is directly related to the quality and production capacity of dry battery shrapnel stamping parts. 1. The professional mold manufacturing mold meets the quality requirements of dry battery shrapnel stamping parts and is suitable for the production of stamping enterprises. The following work should be carried out: (1) Technical exchanges: technical exchanges between departments involve annual production guidelines, equipment capabilities, production capabilities, and production operations Process requirements such as method, selection of mold materials, selection of mold standard parts, mold identification, mold quality requirements and verification standards. (2) Mould drawing countersign: The mould drawing countersign is carried out from the aspects of machine tool matching, safety, production operation, structure, and maintenance. (3) Mold supervision: analysis and summary of mold dynamic management, processing the reasonable changes of mold quality and structure, and ensuring that the mold is completed on schedule according to the quality requirements. (4) Mold verification: focus on parts quality, machine tool matching, safety, production operation, structure, maintenance, etc. In the production site, molds must be verified for stability margin, otherwise product quality is difficult to control. 2. Daily maintenance of the mold The daily maintenance of the mold is one of the important means to ensure the stable quality of dry battery shrapnel products. In order to ensure the quality of mold maintenance, we should focus on the following aspects: (1) Mold maintenance personnel skills training: strengthen maintenance personnel including operating skills, maintenance procedures, mold structure, mold failure analysis and processing, etc. Skill training, build a highly skilled maintenance team. (2) Mold management: conduct dynamic management of mold maintenance, summary of mold files, and provide maintenance plans. (3) Mould cleaning check: Carry out mould cleaning check according to plan to achieve higher mould cleanliness. (4) Mold equipment: According to the mold file, do a good job of mold equipment. The focus is on the management of the spare parts library. To deal with mold repairs with a reasonable inventory, attention should also be paid to the quality of spare parts, because the quality of spare parts also endangers product quality. Production preparation: As the preliminary work of the dry battery shrapnel stamping process, we must carefully prepare for production. The main work has three aspects: 1. For the mold, careful inspection should be carried out, including the appearance, the upper/lower surface, and the completeness of the mold accessories. Complete; 2. The inspection of the sheet material depends on whether it has special marks, scratches, bumps, rust, and double material loss, etc.; 3. Check whether the specifications and models of the work station equipment are prepared according to the process documents. Production operation:'Product quality is manufactured, not detected', this sentence can be fully reflected in the stamping production process, because the correctness of the stamping production operation is directly reflected in the product quality of the stamping parts . In the dry battery shrapnel stamping production operation, the following aspects should be controlled: 1. Process adjustment: adjust various parameters in strict accordance with the 'Stamping Work Benchmark' to ensure accuracy. 2. Mold inspection: check the appearance of the mold, the mold cavity, the sensitivity and reliability of the action of the functional components, and the oil lubrication of the relative moving parts. 3. Equipment inspection: including clutch air pressure, lubricating oil pressure, protective oil pressure, inch movement inspection, and whether there is oil leakage or air leakage, etc. 4. Independent inspection of parts. There are some uncontrollable factors in the stamping production process. Small changes in sheet materials and molds may cause the quality of dry battery shrapnel stamping parts to fluctuate. In order to reduce fluctuations, problems need to be discovered and resolved in time, especially molds. In the early stage of mass production, the independent inspection of the parts is particularly important, because the occurrence of new problems in the quality of the parts is more concentrated in this period. Years of practical experience has proved that if the problems encountered in the initial stage of mold mass production are completely solved, the same problem will occur almost zero in the future. Warehousing and logistics: The production of dry battery shrapnel must have a certain safety stock. In terms of quality, the quality of the warehousing should be paid attention to when storing, to prevent rust, and also to control the transportation speed to prevent bumps and bumps. The above is some experience in the precision stamping production process. Through the strict implementation of the above work, the quality of the dry battery shrapnel stamping parts can be guaranteed to the greatest extent.
