Photovoltaic confluence hardware stamping parts, what are the reasons for cracks in tensile parts + 16 strict quality inspections

The hardware stamping technicians of the manufacturer responsible for the production of photovoltaic confluence hardware stamping parts have 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 bending cracks. Reasons: (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 the one-way V-shaped bending is used; for two-way bending, the bending line and the embossing direction are in line 45 degree. (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 focusing on photovoltaic confluence hardware stamping parts, 5000 square meters 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. Over the past 15 years, I have been conscientious and dedicated to the results of your needs only for the results of your work!
