Jiangsu metal stamping parts manufacturer, the principle of material selection + stamping accuracy up to 0.01mm

The production staff of the Jiangsu metal stamping parts manufacturer introduced that the surface and internal properties of the stamping sheet material have a great influence on the quality of the stamping product, so the selection of stamping materials is also strict. What are the requirements for stamping materials? Xiaoshuo sorted out some relevant information, and let everyone know about it below: 1. Accurate and uniform thickness: 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 the material to jam, and even expand the die. Cracks; too thin a sheet will affect the quality of the finished product, and even cracks during deep drawing. 2. Low yield ratio: the ratio of the yield limit of the material to the strength limit is called the yield ratio. The low yield ratio can not only reduce the deformation resistance, but also reduce the tendency of wrinkling during deep drawing, reduce the amount of springback after bending, and improve the accuracy of the bending part. 3. Low work hardening: work hardening after cold deformation will increase the deformation resistance of the material and make it difficult to continue to deform. Therefore, plates with a low hardening index are generally used. However, materials with a high hardening index have good plastic deformation stability (that is, more uniform plastic deformation) and are not prone to localized cracks. 4. High uniform elongation. In the tensile test, the elongation of the sample before the neck phenomenon begins to appear is called the uniform elongation. During deep drawing, the deformation of any area of u200bu200bthe sheet material cannot exceed the uniform extension range of the material, otherwise uneven deformation will occur. Hardware, 15 years of ingenuity and focus on metal stamping parts processing, 20000+ sets of customized stamping die production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, and 16 quality inspections are strict check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
