Huai'an hardware stamping parts manufacturer, why does the tensile part produce bending cracks + 16 quality inspections

As a manufacturer responsible for the production of Huai'an hardware stamping parts, Xiaoshuo has collected some information for you about the causes of bending cracks in metal stamping stretched parts. Let's take you to understand the causes of bending cracks: (1) Bending lines and plates When the angle of the embossing direction of the 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 should preferably be 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 shearing 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 Huai'an hardware stamping parts manufacturer, 5000 square meter production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, 100+ sets of molds per month The processing capacity and the daily production capacity of 3 million punching times, the punching accuracy can reach 0.01mm, and the 16 quality inspection layers 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 only for the results of the work!
