Dongguan stamping hardware shares with you, it is more practical to understand the performance of these molds-Hardware

Dongguan Stamping Hardware shares with you a practical situation in production. In the production process of stamping dies, the punches and punches are often broken. There are many reasons why the punching needle is easy to break. It may be the cause of the punching needle itself, or the design defect of the mold. It may also be a series of issues such as blanking materials. Foreign precision molds are generally loose, and the stripper plate is very tight. The stripper plate and the die must be fitted with guide posts and guide sleeves. The wire cutting uses slow wire or oil cutting. The male splint is 0.02~0.06mm on both sides. The two sides of the material board are 0.01mm or even tightly matched. Domestic practices are somewhat different. Generally, the unilateral tolerance of the male splint is ±5μ, and the single side of the stripper is 0.01mm; when using slow wire walking, you can consider increasing it appropriately. If the punching needle is offset, it is necessary to make the punching needle as short as possible, the gap should be appropriate, the guide post should be larger, and the gap between the guide sleeve of the cavity and the die should not exceed 0.005mm on one side. The clearance of the stripper plate is smaller than that of the lower template, generally 0.005mm on both sides and 0.02mm on both sides of the male splint. The loose point does not matter. The punch should not be knocked in by force, just push it in by hand.
