Description

Longitudinal crack: the outer circumference of the cemented carbide core is unprocessed, the inner hole of the die sleeve is poorly processed, and the tapered hole, the trapezoidal hole, the inserting interference is insufficient, the geometric angle is unreasonable, the compression amount is too large, and the hard alloy defect Or the selection of the grade is not appropriate, the material tensile strength is not enough.     Cross-cracking: the outer circumference of the hard alloy is unprocessed, the inner hole of the die sleeve is of poor quality, stepped, the upper and lower bumps are inlaid, the defects of the hard alloy are not properly selected, and the tensile strength of the material is insufficient;     Running number: hard alloy material is not wear-resistant, and lubrication is not good during stretching operation;
