cold forging machine made in China

The double-cylinder upsetting machine adopts the mechanical structure completed by the extrusion and clamping synchronously, and uses the principle of cold heading to pre-form the plastic section of the end of the steel bar to be coarsely deformed, so that the diameter of the The large bar of the processing section is increased and the diameter is increased, and the effective diameter is increased. The large 4~6mm, the cross-sectional area after the upsetting is much larger than the cross-sectional area of the original steel base material , greatly improving the tensile strength of the joint., then can set silk of steel bar to finish reinforced connection, the machine
