钢结硬质合金 TLMW50一般都用于冷模具,我们将它用于热镦螺帽成型模上,使用效果较为理想。原用3Cr2W8V 钢制模具,班产平均为11250件,使用寿命为4天(两个面都已用完,超差)。现改用TLMW50后,平均班产11947件,上模用了24天,下模用了31天,由于多次打双件而损伤,但另一个 Steel bonded carbide TLMW50 are generally used for cold mold, we will use it for hot heading nut forming die, the use of more satisfactory results. The original 3Cr2W8V steel mold, the average production of 11250, the service life of 4 days (both sides have run out of tolerance). Now switched to TLMW50, the average production 11,947, the mold used for 24 days, the mold used for 31 days, as a result of multiple hit two-piece damage, but another
