Descriptions of Rebar cold extrusion press machine:
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 cold extrusion machine structure compact has several advantages as below:
1 Stable connection process, convenient construction, easy operation.
2 Joint’s performance is reliable, quality is easy to check and control, and not affected by welding performance of rebar.
3 It is not affected by climate change, can be all-weather operations.
4 Fast extrusion splicing speed, high work efficiency, in general, it can increase 3-5 times on work efficiency compared with electric arc welding joint.
5 It is suitable for various specifications especially splicing of large-diameter rebar, and suitable for splicing of rebar in any position and direction (horizontal, vertical, surrounded by dense or diagonal).
6 No naked fire in construct, eliminate the fire hazards, can be operated in Inflammable, explosive construction site, etc.
7 The extrusion equipment is small volume, light weight, flexible operation, used with balancer, one person can move up and down by a hand to extrusion rebar conveniently.
8 Using cold extrusion splicing can remove lots of welding equipments in construction site and a large amount of acetylene, oxygen, etc. Compared with lap welding, can save lots of steel, comprehensive economic and technical effect is remarkable.
