Measuring method of metal stamping parts1

Metal stamping parts are very common metal processing products in life, and their role is also very important. Precision-Committed to the processing and customization of metal stamping parts for more than 10 years, and has accumulated rich experience in production. Next, let's understand the measurement method of metal stamping parts. Accurate measurement of metal stamping parts takes a small value in accordance with the precise measurement method of the stop gauge. Therefore, the small value can generally be recorded when the vernier caliper is used for accurate measurement and recording. The maximum value and the average value of metal stamping parts processing record have no practical significance. For the precise measurement of the diameter difference in all positions, it should be recorded in the concentricity of the dimensional tolerance, not the diameter. In addition, if the stamping parts processing is a surveying and mapping project, and there is no specification to refer to, you should depend on its cross-sectional condition. You cannot just take the average value. For example, the small value you accurately measured may be a certain punching needle. It is caused by point wear. At this time, the bright band of the cross section is small, so this small value is meaningless. Generally speaking, punching needle wear in stamping processing plants is caused by the shrinkage of the punching machine (special-shaped holes need in-depth analysis). Therefore, in the case of surveying and mapping engineering, the maximum value can be taken. Don't forget the cross-sectional quality. In the case of manufacturing, the maximum value within the tolerance of the basic specifications of the diameter is multiplied by 0.5~0.75. The metal stamping parts have a wear rate, and after a period of time, the punching machine is used to shrink, but if the cross-sectional quality is still acceptable, then the The value is still within the dimensional tolerance range, and the maximum value is appropriate at this time.
