Changan hardware stamping parts, what are the requirements of stamping parts materials + hundreds of precision processing production equipment

The manufacturer hardware responsible for the production of Changan hardware stamping parts said that the surface and internal properties of the sheet metal used in stamping have a great impact on the quality of the stamped products. Following Xiaoshuo's experience based on actual production, will take you to understand the requirements for stamping materials: ①The thickness is accurate and uniform. The stamping die is precise and has a small gap. If the thickness of the sheet is too large, it will increase the deformation force and cause jamming and even burst the die. If the sheet is too thin, it will affect the quality of the finished product and even crack during deep drawing. ②The surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. All surface defects will remain on the surface of the finished workpiece, and the crack defects may extend deep and wide during the process of bending, deep drawing, forming, etc., resulting in waste products. ③The yield strength is uniform without obvious directionality. Anisotropy (see plastic deformation in the drawing, flanging, bulging and other stamping processes, due to the occurrence of all-directional yielding, the inconsistent amount of plastic deformation will cause uneven deformation and inaccurate forming. Inferior product or scrap. ④High uniform elongation. In the tensile test, the elongation before the neck phenomenon of the sample begins to be called uniform elongation. During deep drawing, the deformation of any area of u200bu200bthe sheet cannot exceed the uniformity of the material Extend the range, otherwise there will be uneven deformation, etc. Excellence is the constant pursuit of people.
