Packaging steel strip manufacturers introduce the advantages and disadvantages of the steel strip die
Compared with ordinary steel die, steel strip die has obvious advantages such as saving man-hours, steel material, cost and a certain degree of running life.
Under normal circumstances, because part of the mold material is wood laminate, it is more convenient to process, so compared with general steel punching, it can save about 80% of man-hours, which can significantly shorten the mold production cycle. For medium-sized and large-sized blanking dies, the steel belt die can also save 80-90% of the steel for moulding, thus reducing the cost of moulding by 80-90% compared with the general steel mould. The larger the size of the part, the more obvious the superiority embodied in the economy.
The steel belt die also has a certain service life. When punching thin steel plates or non-ferrous metal parts, its life span can reach 200,000 to 300,000 times. Before the trip, the one-time sharpening life of the inner blanking 3-4 mm steel plate has exceeded 4000-5000 times. In addition, this kind of die also has the advantages of low manufacturing technical difficulty and easy to master; templates and steel belts can be re-used after reforming; the weight of the die is light (more than 80% less than the steel die); and the storage area is small. The comparison between steel strip die and general steel die is shown in Table 4-2.
However, the steel strip mold also has the following shortcomings: ①The production efficiency is low, and the punching parts need to be manually taken out for the upper and unloading materials; ②It does not stand on the punching parts with a thickness of less than 0.35 mm (due to the side pressure of the steel belt). The resulting elastic deformation will increase the punching gap between the convex and concave dies); ③It is not suitable to punch the parts with high precision requirements, and the outer contour size tolerance of the blanking parts is within the range of 0.4 mm, and the blanking and punching At this time, the hole diameter is within 0.12 mm.
