Brief introduction of the characteristics of the cutter type packaging steel strip die
　　 Since the upper half of the cutter-type steel belt die is a flat plate, the structure is simple, there is no reasonable gap between the convex and concave dies, and the die itself has no rhyme guide pin guide set. Therefore, the manufacturing cycle is short, the cost is low, and the installation of the mold is also very convenient. However, because the half of the die of this type of die uses a flat plate, there is no edge, and the edge of the steel belt must be angled, so the edge strength is very low, and the thickness and service life of the parts that can be blanked are relatively limited. Sex. In addition, the surface of the plate will be pressed by the tip of the knife every time it is punched, and the plate needs to be moved frequently during the punching to make the old knife marks stagger the blade. Therefore, this die is not suitable for mass and medium batch production. Finally, it should be pointed out that when using a cutter-type steel strip die, the lower pole position of the punch slider must be strictly adjusted to ensure the separation of the punching parts and avoid excessively deep molds to extend the life of the blade and avoid The recoil force caused by excessive compression of the unloader.
