Talking about the selection principle of precision stamping die

It is especially important to choose the right material before precision mold processing. It is necessary to select the appropriate steel according to the customer's service life and performance requirements of the mold, and to estimate the working strength and force capacity of the precision mold. Below, the author of the hardware factory will organize and introduce the selection principles of precision stamping molds for everyone. 1. Wear resistance When the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing violent friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. 2. Strength and toughness Most of the working conditions of the mold are very bad, and some often bear greater impact load and cause brittle fracture. In order to prevent the sudden brittle fracture of the precision stamping parts of the mold during work, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organization state of the material. 3. Fatigue fracture performance During the mold work process, under the long-term action of cyclic stress, fatigue fracture is often caused. Its forms include low-energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
