Stamping die, know these 5 points, you are also an expert [hardware]

Stamping dies are the production of stamping parts that we usually contact, and we need to process one step first. The quality of stamping die design, processing, assembly and other aspects determines the quality of stamping parts. Xiaoshuo sorts out a few points and takes you to understand the stamping die: 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 vibration between the surface of the cavity and the blank. Friction, resulting in mold failure due to wear. Therefore, the wear resistance of the material is one of the 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: The working conditions of the molds are mostly very bad, and some of them are often subjected to larger impact loads, resulting in brittle fracture. In order to prevent sudden brittle fracture of mold parts 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. High temperature performance: When the working temperature of the mold is higher, the hardness and strength will decrease, leading to early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high anti-tempering stability to ensure that the mold has high hardness and strength at the working temperature. 4. Resistance to cold and heat fatigue: some molds are in a state of repeated heating and cooling during the working process, which causes the surface of the cavity to be stretched and pressure to change stress, causing surface cracks and peeling, increasing friction and hindering plastic deformation , Reducing the dimensional accuracy, resulting in mold failure. Hot and cold fatigue is one of the main forms of failure of hot work molds. This type of mold should have high resistance to cold and heat fatigue. 5. Fatigue fracture performance: In the process of mold work, 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. The fatigue fracture performance of the mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
