Cold extrusion connection of steel bars is to insert the steel bars to be connected to the extrusion sleeves. Then the sleeves are extruded with extrusion pliers to produce a joint form that is plastic deformation and tight compression of the ribbed steel surface. Compared with the traditional lap joint and welding technology, cold extrusion technology has the advantages of stable and reliable joint quality, free from environmental impact, round-the-clock construction, good shock resistance, and low-temperature resistance. The rebar cold extrusion press machine is used by the ultra-high pressure pumping station, the high-pressure oil pipe, and the extrusion tongs, and the compression dies to complete the extrusion connection.
