Hardware stamping parts manufacturers, what to do about the quenching deformation of stamping dies [Hardware]

Manufacturers of metal stamping parts mostly have the ability to open molds independently. In the selection of steel for stamping dies, there will be a quenching process. Don't underestimate this step. The life and wear of the entire mold are all determined by quenching. Xiaoshuo will work with you to understand the knowledge about quenching: 1. Reason for deformation: unreasonable selection of parts. Solution: Use steel correctly. For parts with large differences in cross-sections and complex shapes, alloy tool steels should be used as much as possible. 2. Reason for deformation: unreasonable forging process. Solution: Reasonably control the forging temperature and forging process, and pay attention to the directionality of the material. After forging, it must be annealed. 3. The cause of deformation: The heating process is not strictly controlled. Solution: Reasonably select and control the heating temperature. The lower limit of the quenching temperature is generally selected, and the first preheating is generally used when heating. For parts that are large in size and only require surface hardness, rapid heating can be used. 4. The cause of deformation: the tempering process is incorrect. Solution: ① After the workpiece is taken out of the coolant, it should not stay in the air, and immediately transferred to the tempering furnace for tempering. ② Choose the tempering temperature reasonably, not too high or too low, sometimes the method of multiple tempering can be used. ③Using convex and concave mold limited shape quenching and sleeve tempering process. That is, the concave mold is first quenched without tempering, and then the convex mold is quenched, removed from the coolant, and stuffed into the concave mold. After isothermally cooling to room temperature, it is combined and tempered together.
