Process characteristics of packaging steel strip sheet die

Process characteristics of packaging steel strip sheet die
　　The thin plate die is made of a thin steel tape that has been heat-treated (HRC40-45) in advance as the die, so after the die is made, heat treatment is not necessary to avoid the deformation caused by the heat treatment, thereby eliminating the need for correction deformation的processes. There are several methods for making molds, such as fitter processing after imprinting, wire cutting processing, and punching of thin plate die with backing plate hole. These types of manufacturing processes are relatively simple and can produce high-precision molds in a short time. In addition, the holes of the die, the unloading plate and the backing plate can be processed by wire cutting at the same time, which not only shortens the cycle, but also facilitates assembly.
　　 The gap value of the convex and concave dies of the thin plate die is not strict. For various materials with a thickness of only one millimeter, the blanking gap is within 0.1 mm; when the precision of the punch is low, the gap can also be adjusted Zoom in to 0.15-0.2 mm.
　　Using a zinc-based alloy die to punch a thin plate die, and fix it on the zinc-based alloy die, it can be made into a zinc-based alloy thin plate laminated die to improve the service life of the zinc-based alloy die and punching parts Accuracy. When the die of the conventional die is used and is about to be scrapped, several thin plates can also be fixed on the die and punched into a thin plate die in turn to prolong the service life of the die.
