The advantages and disadvantages of packaging steel strip punch

Packing and the advantages and disadvantages of the steel strip die steel band punching die, compared with common steel die has obvious save working hours, the service life of steel, costs, and can have certain advantages. In general, as part of the mould material is wood laminated board, processing more convenient, so compared with the general steel die, can save time by about 80%, which school can significantly shorten the mold production cycle. For medium and large stamping die set, packing tape punch can save molding steel 90 - 95%, making the moulding costs 80 - less than ordinary steel 90%. Parts size is larger, and around the superiority of embodied on the negative effect. Packaging steel strip die but also has the certain service life. In the blanking of thin steel or nonferrous metal parts, its life up to 20 - 300000 times. At present, the domestic blanking 3 - A life of grinding, 4 mm steel plate for more than 4000 - 5000 times. In addition, the school also has low manufacturing technology difficulty, easy to grasp. Template, packaging steel strip by restructuring and repeated use; Mould light weight ( Daniel has to reduce more than 80%) than steel ; Storage area is small, etc. The packing of steel strip with ordinary steel die for stamping dies - contrast are shown in table 4 2. But the packaging steel strip mold also has the following disadvantages: (1) the production efficiency is low, the discharging forging by artificial to remove salt pieces; (2) should not be made the thickness of the system with small dry 0. The mold 35 mm. ( Due to the packaging steel strip produced by foot pressure elastic deformation increases convex, concave die blanking clearance) ; (3) should not be blanking to disappear to demand higher parts, 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 m range.
