Stamping parts processing, what causes the tensile cracks [hardware]

Stamping processing, drawing process is a relatively common processing technology. When stretching, you will often encounter stretching wrinkles and cracks. What are the problems caused by it? Xiaoshuo organizes a few points and shares with you: 1. When the angle between the bending line and the embossing direction of the sheet material does not meet the required layout, the bending line should be perpendicular to the embossing direction when one-way V-shaped bending; when two-way bending, The bending line and the embossing direction are generally 45 degrees. 2. The material of the stretched parts has poor plasticity. 3. The bending radius is too small and the pickling quality is poor. 4. Insufficient lubrication-high friction. 5. The fillet radius of the convex and concave mold is worn or the gap is too small-the feeding resistance increases. 6. The quality of the cut and blanking sections of the stretched parts is poor-burrs and cracks. 7. Material thickness is seriously out of tolerance-difficult to feed hardware, 15 years of ingenuity focused on stamping parts processing, 20000+ sets of stamping die custom production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punches, stamping accuracy Up to 0.01mm, 16 quality inspections are strictly for quality control. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
