Cutting knife type packing with the characteristics of the die steel profile

Packaging steel strip the characteristics of the die cutting knife type profile due to cutting knife type steel strip punch of the upper die is flat plate, structure is simple, there is no reasonable gap problem between the convex and concave die, punching die itself blank guide pin guide suit. Therefore, short manufacturing cycle, low cost, and the mould is also easy to install. But as a result of the punching die half mold used is flat, no edge, steel belt must take bevel edge, so the blade intensity is very low, for can cutting thickness and the service life of parts has great limitations. In addition, the flat surface at every time of cutting will be point pressure out of mark, need to often move the tablet in the blanking, make old scar stagger the blade. Therefore, the die is not suitable for large and in batch production. Finally, pointed out that using die cutting knife type steel, must be strictly adjust punch block under the pole position, both to ensure the stamping separation, and want to avoid to die too deeply, in order to prolong the harbor life of blade and avoid causing discharger compression is too large, resulting in a long-term.
