Quality management of stamping forming

Stamping forming is a very mature metal processing technology, and the stamping parts produced are widely used. The quality management of stamping forming is based on the forecast analysis of statistical analysis control measures and the whole process of supervision to carry out real-time adjustment, thereby improving the production speed and production economic benefits. Next, let's look at how to carry out the quality management of the stamping forming process. 1. Increasing non-destructive testing technology In order to remove the cause of deviations in the entire process of mold production and manufacturing, it is necessary to do a good job in installation and adjustment. The coloring method can be used to carry out the test punching, and the touch and fluidity of the board during stretching can be reflected according to the fade condition, and then it is possible to remove the wrinkle or cracking problems of the stamping part during the whole stretching process. First, grasp the use skills and methods of measuring instruments, micrometers, scales, and micrometers before testing. Inspection staff must master the precise measurement limits and scope. The inspection of stamping parts is a key way to prevent stamping parts from causing mass problems. The second is the matching specification inspection. This inspection method is carried out in accordance with the actual operation manual of the tooling and fixture. The precise measurement content is combined with the actual part condition in-depth analysis, and then the appropriate adjustment of the mold will achieve very good actual results. The second is to improve the quality of the inspection staff. The current level of stamping die employees is low, and it is inevitable that there will be quick success and instant benefits in the whole process. Therefore, the first sample of stamping parts can only be produced after the first sample has reached the standard. It can be mass-produced, and it is necessary to prevent forming changes during mass production. Second, the sequence diagram method The purpose of the drawing sequence diagram depends on the visualization in a graphical way, so that the manufacturer can determine where to start to improve product quality. Among the elements of product quality problems caused by stamping parts, the quality status and reasons are generally classified, and the frequently occurring product quality problems and the often influencing factors are searched for. 3. Control chart method Control chart method is the use of statistical analysis technology to complete the process management, mainly to carry out the control chart according to the standard of each process in the whole process of dynamic production, and take certain effective measures to control the cost. .
