Reasons and preventive measures for the outer wall of tensile parts to be cracked

With the development of society, hardware stretch products have been widely used in various fields. A very common problem with stretched parts is that the outer wall will break when stretched. Precision has been focusing on precision drawing parts for more than 10 years. Next, we will introduce several main reasons for the cracks on the outer wall of the drawing parts during the drawing process. 1. The radial tensile stress that the material bears during the stretching process cannot be too large; 2. The radius of the die fillet may be too small; 3. The lubrication is poor during stretching; 4. The plasticity of the raw material is poor. 5. It is related to the tensile strength of the force transmission area of u200bu200bthe outer wall. 6. It is related to the tensile stress of the force transmission area of u200bu200bthe outer wall. 7. When the tensile stress of the outer wall exceeds the tensile strength of the outer wall material, the tensile part will be rounded at the bottom and outer wall The tangent 'danger zone' breaks.
