upsetting machine that increases the bar diameter

Product Details

Rebar upsetting machine using hydraulic cold heading of the principle of plastic deformation of steel ends, the diameter increases 4 ~ 6mm, and then processing thread. So that the actual cross-sectional area after processing thread larger than the original cross-sectional area of steel, greatly improving the tensile strength joints.

This upsetting of the threaded connector by the tensile test of all broken in the base metal for the higher requirements of engineering steel upsetting machine hydraulic technology, upsetting steel for straight thread connection technology, the use of sleeve connector . The device is suitable for the diameter of 16 ~ 40mmHRB335 (Ⅱ grade steel), HRB400 (Ⅲ grade steel) hot-rolled ribbed steel production upsetting straight thread steel joint.
