Those who master hardware stamping dies all know that before mass production and use of dies, we should carry out die inspection, so that the finished products we manufacture will be more accurate, so do you know why we should inspect dies? What is the key reason?


The purpose of die test in metal stamping parts factory is to determine the quality and characteristics of stamping parts. This is because stamping parts must pass through product design, process technology, die design, die parts processing, die assembly and other processes. Any errors in these processes will cause the die characteristics to be degraded, and the qualified products cannot be manufactured. Therefore, after the die is assembled, it must be stamped under production conditions. According to the design drawings of stamped finished products and product parts, check whether its quality and specifications meet the requirements of drawings, and whether the die movement is reasonable and reliable. According to the difficult problems in the stamping process, analyze the reasons and correct the reasons, so that the die can manufacture qualified parts and be put into production safely and stably


After stamping and producing up-to-standard samples, master the methods and laws of commercial parts in the stamping process, and provide reliable technological basis for mass production of dies. In the production of cold stamping die in metal stamping parts factory, it is difficult to accurately measure the size and shape of blank before deformation for some product parts with complex shape or high precision. In order to obtain more accurate vacancy shape, size and material standard, it can only be decided by repeatedly adjusting the die to manufacture up-to-standard parts.


In die design and process technology, it is difficult to determine some process dimensions according to calculation methods, such as complex protrusions of drawing dies, circular arcs of die cavities, and geometric shapes and specifications of some positions. The metal stamping parts factory must carry out stamping and blank holding synchronously, and the shape and specification of the parts can be determined only after the standard parts are realized. After the adjustment is completed, the problems exposed in the process, die design and manufacturing, adjustment situation and solutions are fed back to relevant design and process units, providing reference for the next design and manufacturing, and improving the level of die design and processing. The metal stamping parts factory verified the quality and precision of the die according to the die experiment, which brought the basis for future production.
