Cold Hydraulic Extrusion Press System

1. Description of cold hydraulic extrusion machine
The machine including two set of machine:
1) YJ650: process rebar whose diameter is from 16mm to 32mm.
2) YJ800: Process rebar whose diameter is from 36mm to 40mm.
3) YJ650 machine and Pressure equipment of YJ800 can process diameter 16-40mm.
2. Working principle 
It can link the rebar with sidewise extrucion by the cold extrusion press machine, make the coupler plastic deformation then occlude tightly with the steel in order to link the rebar.

 3. Advantages 
a. Because of good resistence of the joint,it is widely used in bridge construction projects.
b. Able to work under all conditions without affect from weather.
c. Easy to press rebars with light weight.

5.Why choose JBCZ 
1. High tensile strength and the strength reach Grade II  (Equal to the parent material's);
2. Working rang : Φ16mm-Φ40mm
3. Strong intensity connector, stable and reliable; no specific requirements on the weldablility of the rebar;
4. Only needs 1 - 3m to stamp each connector, which is about ten times faster than ordinary welding;
5. Only 1 - 3 KW power of oil pump , which is not limited by power capacity,
has flexible structure and suitable for operation on several machines;
6. No flammable gases, not affected by rainy or cold weather;
7. Relieve congestion of the connecting point, facilitated concrete pouring;
8. No professional and experienced worker needed, able to
connect changed steel bar of different diameters;
9.Save 80% of connector steel consumption.

Lenton Standard Anchor Bolt Rebar Coupler Product Description: Description of lenton anchor bolt coupler ,Lock head rebar coupler, Ancon type MBT coupler, SCREW COUPLER, rebar couplers is a kind of rebar coupler, without make any thread on rebar.  We can customized the lenton anchor bolt coupler according to client requirement. And we also have standard rebar coupler, like parallel threaded coupler, no threaded coupler, taper threaded coupler, weld threaded coupler and so on. Installation Instruction 1. Put the end of first bar into Unitec bolt coupler until touch the center pin, using wrench to rotate the bolt from the center to the outside vigorously and adjust the center of stel bar. 2. Using the electric drive(air wrench) to tight the bolt from the center to the outside, until the head of bolt cut off. 3. Put the second steel bar into the coupler until touch the center pin, and repeat the operation. When using the wrench to tight the bolt, m...
