16mm - 40mm Rebar Processing Machine , Hydraulic Type Rebar Cold Stamping Machine
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.
Composition
Cold extrusion press equipment is made up of rebar extrusion press machine, ultra-high pressure pump, balancer, etc.
1. Cold extrusion press equipment
(1) CRS-32 rebar extrusion press machine is key tool of cold extrusion press equipment, it mainly used in extruding Φ18-Φ40mm II grade III grade deformative rebar joint. Remove pressure die, change shear die, it can used as simple shear apparatus, and suitable for shear of various rebars in construction sites.
CRS-32 rebar extrusion press machine is equipped with CRS-80 Ultra-high pressure pump, compact structure, small volume, light weight, easy operation, is a kind of portable hydraulic machinery, suitable for field operation, working aloft, etc. Diagram 1:

Main parameter of CRS-32 rebar extrusion press machine:
| Rated extrusion pressure | 300KN-600KN |
| It can process rebar diameter | 16mm-32mm |
| Dimension | Φ140*426mm |
| Working operation | 300mm-400mm |
| Weight | 32kg |
CRS-32 rebar extrusion press machine use high pressure to work, thus extrusion pressure is large, small volume, rack width is small, flexibility is good, can be used in situation where deformative rebars is dense and spacing is small. Diagram 2:
2. CRS-80 ultra-high pressure pump
Ultra-high pressure pump is power producer of cold extrusion press machine; the output pressure can reach 100MPa. Ultra-high pressure pump use radial piston pump, long life, high efficiency, good self-priming performance, simple structure, easy to use, etc.
Main parameter:
| Rated working pressure | 80MPa |
| Max working pressure | 100MPa |
| Motor power | 3kw |
| Weight | 58kg |
Advantages:
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.
