1. The best die punch material must be ASP60 punch material, but it is expensive. The punch material commonly used in continuous stamping dies is pre-hardened punch material SKH-9 high-speed steel. The commonly used punch material for stamping stainless steel is pre-hardened punch material ASP60 powder high-speed steel. The punch material CR12MOV is used for ordinary single punch dies.
2. The most common material for die punching needles is 45 steel. The hardness of the raw material is only about 16°, and the hardness of clinker can reach 52-55°. Although the effect is not very good, there is still a certain market demand.
Of course, it's also cheap. Slightly better is SKD11, heat treated HRC58-60 degrees, generally used to punch stainless steel very thin plates.
3. The use of SKH51 high-speed steel: cold stamping die, embossing die, cold forming roll, cutter, reamer, drill, tap, punch, etc.
Therefore, the SKH51 punch is suitable for cold die design stamping, with high toughness, and the SKH51 punch for stainless steel with a thickness of more than 6mm is very punch-resistant, 3 times higher than the SKD11 punch.
4. Strong bearing capacity, the representative material of stamping die punching needle SKH-51 SKH-. What are the three commonly used cold stamping materials? The alloy of the stamping die and the steel are hardenedMost of the materials used to make the stamping die are mainly steel.
5. There are also tooth punch needles, detection pins, hexagonal punch needles, elliptical punch needles, forming punch needles, fan punch needles, special-shaped punch needles, high-speed steel punch needles, tungsten steel punch needles, etc., which can be understood by searching and viewing the best of these products. Stainless steel punching is a common process operation, and more materials are required.
6. The punching needle is an indispensable accessory when the stamping die is working, which is a replaceable mold consumables, which is installed on the stamping die for continuous punching and stamping and punching operations, so that the processed materials are separated or plastically deformed, so as to obtain the required finished or semi-finished products.
