What should I do if the shape and size of the processed stamping and bending parts do not meet the standards?

Stamping and bending parts are the most common type of metal stamping parts by the most manufacturers, but in actual processing, it often appears that the shape and size of the processed product meet the drawing standards. In fact, there are many reasons for this situation. Only by carefully analyzing the reasons can we better solve these problems. So what should I do if the shape and size of the processed stamping and bending parts do not meet the standards? The following are some of the reasons that affect the shape and size of stamping and bending parts that do not meet the standards summarized in the daily stamping production: 1. The reason for the stamping die Bending stamping die is a tool for bending stamping parts. Generally, the shape and size of the bending stamping part depends on the size of the working part of the stamping die. The more precise the size of the stamping die is, the more precise the shape and size of the bending part. In addition, the reliability of the pressing device and positioning device used in the stamping die structure will also have a greater impact on the shape and size of the bending part. 2. The reason for the material The different materials used in the bending part will also affect the shape and size of the bending part. There are two main reasons for this: On the one hand, the mechanical properties of the material and the uneven distribution of components, for the stamping parts bent from the same sheet material, due to the different pressure and springback values, the shape and size of the stamping parts will be deviated; On the other hand, the uneven thickness of the material will also cause the size and shape of the bent stamping parts to vary. 3. The reason for the bending process When the number of processes for bending stamping parts increases, the cumulative error caused by the deviation of each process will also increase. In addition, the different arrangement sequence before and after the process will also have a great influence on the size. For example, for a bent piece with holes, when the hole is first bent and then punched, the shape and position of the hole are much higher than when the hole is first punched and then bent. 4. The reason of the process operation The installation and adjustment of the stamping die and the proficiency of the production operation will have a certain impact. For example, the accuracy of the feeding and the reliability of the positioning of the steel plate will affect the shape and size of the bending part. 5. The reason for the punch is that when bending, different punch models, different tonnage sizes, and different working speeds will change the size of the bending parts. In addition, the size of the punch itself will also have a certain impact. 6. The cause of the bending piece itself The shape of the bending piece is asymmetrical, or its outer size is large, which will cause a large deviation in the bending process. In view of the above main reasons, if prevention and correction are taken in actual production, the bending parts with higher dimensions can be produced.
