The advantages and disadvantages of steel tape punch

Packaging steel strip manufacturer to introduce the advantages and disadvantages of steel strip die steel with punching die, compared with common steel die has obvious saves hours, cost of steel, and can have the advantages of the use of a certain environment. In general, as part of the mould material is wood laminated board, processing more convenient, so compared with the general steel at the school, can save time by about 80%, thus can significantly shorten the mold production cycle. For medium and large blanking die, die steel band are can save molding steel 80 - 90%, making the moulding costs 80 - less than ordinary steel 90%. Parts size is larger, in the circle economy embodies the superiority of the more significant. Steel tape punch but also has the certain service life. In the blanking of thin steel or nonferrous metal parts, its life up to 20 - 300000 times. Before, because of the blanking 3 - A life of grinding, 4 mm steel plate for more than 4000 - 5000 times. In addition, this kind of die also has low manufacturing technology difficulty, easy to learn; Template, steel strip by restructuring and reuse; Mould light weight ( Than steel mold to reduce more than 80%) ; Storage area is small, etc. Compared with general steel die steel belt die - see table 4 2. However, steel strip mold also has the following disadvantages: (1) the production efficiency is low, the discharging to remove salt pieces by artificial; (2) not in coining thickness less than 0. The 35 mm parts ( Due to the elastic deformation of steel strip produced by lateral pressure increases convex and concave die blanking clearance) ; (3) should not be requiring higher precision blanking part, outside of the blanking parts contour size tolerance about 0. The range of 4 mm, blanking and punching when Lord kung Lao about 0. 12 mm range.
