Working principle of Steel Bar Cold Extrusion Press Crimping Machine
The steel bar cold extrusion machine is to insert two steel bars to be connected into the special steel bar connection sleeve and extrude the steel bar sleeve through the cold extrusion equipment to make it tightly combined with the steel bar.
The equipment that connects the two steel bars into one, that is to say, inserts the steel bars to be connected into the extrusion sleeve and squeezes the sleeve with the extrusion pliers to produce a joint formed by plastic deformation and the surface of the ribbed steel bar tightly pressed together. Better than the traditional lap joint and welding technology, it has the advantages of stable joint quality, no environmental impact, all-weather construction, good joint shock resistance, low-temperature resistance, etc. The technical construction is fast, and the traditional welding method can save a lot of time in construction: the cold extrusion technology of the steel bar can reduce the engineering cost compared with the traditional steel welding connection construction.
Advantages of Steel Bar Upsetting Machine
(1) steel sleeve cold extrusion connection technology construction process is simple and easy to grasp.
(2) The construction of the steel sleeve cold extrusion connection technology is quick. Compared with the traditional welding method, it can save a lot of time.
(3) The steel sleeve cold extrusion connection technology can reduce engineering costs compared with traditional steel welding connection construction.
(4) The steel sleeve cold extrusion connection technology is suitable for the radial extrusion connection of ribbed steel bars with diameters of φ16-φ40 in reinforced concrete structures.
