Gaotang Hardware Stamping Parts Factory, what are the reasons for the cracks in the tensile parts + 16 strict quality inspections

The stamping technician in charge of the hardware of Gaotang Hardware Stamping Parts Factory has said about the causes of bending cracks in metal stamping tensile parts. Xiaoshuo has collected some information for you based on actual practice. Let's take you to understand the causes of bending cracks. : (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 45 degrees . (2) The plasticity of the tensile parts is poor. (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 feed resistance increases. (6) The quality of the shear and blanking sections of the stretched parts is poor-burrs and cracks. (7) The thickness of the material is seriously out of tolerance-difficult to feed hardware, 15 years of focus on Gaotang hardware stamping parts factory, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, 100+ sets per month The mold processing capacity and the daily production capacity of 3 million punching times, the punching accuracy can reach 0.01mm, and the 16 quality inspections are strictly controlled. It can quickly solve the urgent problem of time when choosing hardware stamping processing, solve the problem of stamping accuracy, and solve the problem of production quality. For 15 years, I have been conscientious and dedicated to the results of your needs for the results of work!
