High-speed presses die life is how long? How to improve die life?
To know that high-speed presses die life, we must first understand the composition of high-speed presses mold: mold materials into high-speed steel and tungsten steel, and our die Dongguan SAMHOOR of high-speed presses are used tungsten steel, cost at 3-10 about million, or even more expensive. A good horse with a good saddle, high-speed presses only configured mold, can play a high-speed presses genuine charm. High-speed presses mold is machined by way of Fast wire, wire walking way compared to the low-speed punch use, fast wire and wire walking processing methods vary a lot. If the customer requires smooth and high precision molds with a mold to be sure to select wire walking, because with wire walking processing method produced mold, can achieve better results by finishing; high material, high cost , comprehensive mold service life of high-speed presses is 3-5 times the low-speed punch. Mold under normal operation, the service life of up to 5--10 years.
Ordinary punch single punch single punch die processing different from the high-speed presses with progressive die are high-speed processing, let's say something about how to improve die life continuous method:
1, to improve the life of small convex mold
For material thickness less than or equal to the diameter of the small convex mold for the continuous high-speed punch die sets are installed on expanding protection devices, while the need for high-speed presses molds for small convex mold gap value and structure of the leak in part of targeted improvements , 8% increase from the original design of the double-sided gap value to 14-15%, the height of the change in shape of the concave mold inserts, the edge portion is set to 2-2.5 times the thickness of the material, the getter portion (tapered surface ) roughness of Ral.6. These improvements enable continuous high-speed presses die life greatly improved.
2, convex mold can increase the number of grinding
To improve the convex mold can grinding times and ease of handling can be fixed using the new method of high-speed punch presses continuous mold. When the fixed punch without a fixed station, and with a small plate fixed. Each blade will wear a punch groove while sharpening grinding down the same amount at the same punch bottom pad thick steel shim. This structure not only improves the speed punch die punch may be continuous grinding times, installation and disassembly easy.
These two structural improvements through convenient, high-speed presses allow the original molds for each edge grinding time can only be washed about 50 000 products, and now reach every edge grinding time can be washed more than 100,000, some 200,000 die pieces. Greatly improving the speed of production and economic benefits.
