Equipment details

Compared with the intermediate frequency elbow machine, the cold push elbow machine is not as high as the appearance quality and production efficiency of the hot push elbow machine. The cold push elbow machine is in the drawing state when forming the outer arc, and there is no extra metal in other parts to compensate, so the wall thickness at the outer arc is about 10% thinner. But due to the characteristics of suitable for single piece production and low cost, cold push elbow machine technology is mostly used in the manufacture of small batch, thick wall elbow.

The working principle of the intermediate frequency elbow machine is: using the special elbow forming machine, the tube blank is put into the outer mold, after the upper and lower die, under the push of the push rod, the tube blank moves along the gap reserved by the inner mold and the outer mold to complete the forming process.
