12-40mm rebar machanical splicing cold extrusion machine

Specifications Cold extrusion machine is used to process the rebar end.

No specific requirements on the weld ability of the rebar.

   ma 12-40mm rebar machanical splicing cold extrusion machine    Product Description Cold extrusion bar splicing is a new form of mechanical connection, the basic principle is: Insert two un-connected bars into a special connecting sleeve, then use hydraulic tool press sleeve in radial direction, make sleeve occur plastic deformation, thus make sleeve’s inner wall embed the grooves of rebar’s cross rib, finally implement the connection of two bars. Axial force that the rebar bears is mainly through rebar’s rib and the shear force between sleeve after deformation to pass.   The features of this technology:
1.Strong intensity connector, stable and reliable; no specific requirements on the weldablility of the rebar;
2. About ten times faster than ordinary welding;
3. Not limited by power capacity, has flexible structure and suitable for operation on several machines;
No flammable gases, not affected by rainy or cold weather;
Relieve congestion of the connecting point, facilitated concrete pouring;
No professional and experienced worker needed, able to connect changed steel bar of different diameters;
The technology is assessed by the Ministry of Construction as "world advanced, high quality, high efficiency, safe, and economical thick diameter distorted steel bar connection technology which can be widely used in the construction industry."
