Advantages and disadvantages of 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 service life.
Under normal circumstances, because part of the mold material is wood laminate, it is more convenient to process, so compared with ordinary steel die, it can save about 80% of the man-hours, which can significantly shorten the school battle production cycle. For medium-sized and large-sized punching dies, the steel belt die can also save 90-95% of the steel for moulding, thereby reducing the cost of moulding by 80-90% compared with ordinary steel dies. The larger the size of the part, the more obvious the economic advantage.
The steel belt die also has a certain service life. When punching thinner steel plates or non-ferrous metal parts, its life span can reach 200,000 to 300,000 times. At present, the one-time sharpening life of domestic blanking 3-4 mm steel plates has exceeded 4000-5000 times. In addition, this kind of punching also has the advantages of low manufacturing technology and easy to master; templates and steel belts can be re-used after reforming; the weight of the mold is light (more than 80% less than that of the steel mold); 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 belt molds also have the following shortcomings: ①The production efficiency is low, and the upper discharge is left to manually take out the punching parts; ②It is not suitable for 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 When the hole tolerance is about 0.12 mm.
