What are the specifications for the trial punching of the scaffold stamping parts processing die?

Normally, only after confirming in advance that the mold can meet the requirements of use, can the design be carried out according to the mold, and then the material specified in the design can be used for test punching. In this process, we need to pay attention to whether the material should be pre-punched during the processing of scaffold stamping parts, such as annealing, leveling, pickling, phosphating, and so on. So, what are the specifications for the trial punching of the scaffold stamping parts processing die? For this question, there must be many friends who are more interested. First of all, we should ensure that the lubricant used meets the requirements of the lubrication specification; secondly, in order to ensure safe and convenient observation of the deformation law during forming, inching can be used during test punching; in order to avoid obstructing the line of sight, during test punching It should also ensure that its quality standards meet the inspection requirements. In order to ensure the quality and accuracy of the scaffolding stamping parts, we also need to specifically inspect its accuracy. The main contents include: shape size, surface position, hole position, shoulder position, drawing ridge position, shape and size of each main section, etc. It should be noted that when checking the accuracy, special tools should be selected for testing according to its complexity. Among them, when inspecting the appearance of the scaffolding stamping parts, it is generally judged by the hand feeling and vision of the staff. The main contents of this part of the work include: local distortion: distortion, cracks, wrinkles; adhesion; occlusion; unclear or non-overlapping edges; pitting; discontinuous deformation; insufficient stiffness; local impact contours and local crushing, etc. . The above content gives you a brief introduction to the basic specifications that should be followed during the trial punching of the scaffold stamping parts. I hope that through this sharing, everyone has a full understanding of the content of this part, and I also hope that everyone is working in practice. Can pay attention to this issue in the related news: the characteristics of the main materials of stamping parts, the handling of common problems of stamping parts, the characteristics of scaffolding stamping parts and the importance of inspection, the advantages of metal stamping parts introduce the advantages, procedures and characteristics of stamping parts
