Stamping parts matching verification stage

In order to better ensure the quality of automotive stamping parts in the mass production process, the problems of stamping parts and bodywork are in the research and development process. After the development and design of the full-sequence stamping die shell, it is very important to carry out the welding matching verification of the body sub-master process and the master process. necessary. Precision-Committed to custom processing of automotive stamping parts for more than 10 years, and has accumulated rich experience. Next, let's introduce what is the matching verification phase of stamping parts. The function of the tooling fixture is to shape, accurately locate and clamp the stamping parts during the whole welding process to ensure the precision of the overall process after welding, which is the guarantee of the welding precision of the car body. Therefore, the welding match verification activities in the research and development process are based on the calibrated tooling and fixtures as the basis for precision judgment, and check the problems existing in the matching and overlapping of the stamping parts on the welding tooling. When stamping parts are in a stable condition and the compliance rate considers the matching regulations, the welding matching certification will be carried out. When performing matching certification, the compliance rate of stamping parts is specified as the overall compliance rate> 80%, and the standard holes and reference points are 100% up to the standard. During the matching certification, the stamping parts are placed on the fixture tooling in accordance with the matching lap sequence specified by the welding process. First carry out the matching under the random condition of the tooling and fixture (when not clamped), check the overlap of the steel bar between the hole, surface and the product at this time, use special tools such as gap ruler, plug piece and other special tools to carry out accurate measurement of data and information; prefer to remove Intervention points in the middle of the stamping part and between the part and the fixture fulcrum; secondly, record the gap between the stamping part and the auxiliary support point; in the case of clamping, use a micrometer to check the gap of the matching position, and combine the inspection data information of the stamping part to identify the problem Products, make relative rectification requirements. The matching verification of stamping parts is a multi-round repetitive work. From the beginning of the matching verification work to the closing of the problem, it usually requires 2 to 3 rounds of verification. The matching follow-up management method is carried out in the form of a question list, which can supervise the matching problems.
