[0014] Example: An improved process for processing internal threads, the specific steps are as follows:
[0015] Step 1: Stretch pretreatment A: Stretch the set depth at the place where the internal thread needs to be processed on the processed plate, so that the tensile deformation of the plate will form a pit at the place where the internal thread needs to be processed;
[0016] Step 2: Pre-punched hole B: Punch to form a coaxial pre-punched hole at the stretching position;
[0017] Step 3: Sprouting C: Sprouting (that is, flanging, the material is further stretched and deformed) on the pre-punched hole with a punch to form a cylindrical through hole without internal threads;
[0018] Step 4: Tapping: Use a wire tap to tap the threaded hole in the cylindrical through hole after the budding.
[0019] After the above steps, the material is stretched and deformed twice, the stress concentration inside the material is relatively small, and the wall thickness is relatively thick, and it is...
