Brief Introduction Of
Upset Forging Parallel Thread System
With the emergence of high-rise building, large-span space and special structures, the application of building rebar is developed towards big diameter, dense and high strength. The traditional rebar splicing technology such as welding and lapped splicing can not meet the requirements commendably in strength and saving cost. In this condition, as a new rebar connection technology, parallel thread connection technology, especially the upset forging parallel thread connection technology is now more and more adopted in projects.
As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:
1, Wide working range: adaptable for Φ12mm-Φ50mm same diameter, different diameter,
bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706 standard.
2, High strength: stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of bar joint =1.1 times of bar’s specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003, JG171-2005.
3, High efficiency: upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.
4, Environmental protection and economy profit: no environment pollution, can work all day, not affected by weather, economize energy source and bar material
Processing Machine
1. (GD-150 Machine )Rebar End Upset Forging Parallel Thread Machine
| Rebar diameter range: | φ12－φ40 |
| Oil pump flux: | 5L/min |
| Rating power: | ＜60Mpa |
| Electric motor power: | 4KW |
| Piston movement distance: | 100mm |
| Out dimension(mm): | 1225×570×1100mm |
| Weight: | 597Kg |
This machine is the preparative machine for rebar connection in construction work. Its main function is to forging the end part of rebar to raise the rebar area and therefore enlarge the strength of rebar end.
2. (GZ-45Machine )Steel bar Parallel ThreadCuttingMachine
| Rebar diameter range: | φ16－φ40 |
| Threading cutting speed | 32r/min |
| Backing speed | 64r/min |
