Building Construction Steel Rebar Processing Machine Three Phase Easy Operation
Advantages:
1. The tensile strength of this system can be reach 1.1 times of steel bar, make sure 100% BAR BREAK;
2. Easy operation, high efficiency, forging and threading one rebar end only cost no more than one minute.
Principle:
First, we use Upset Forging machine to forging the end of rebar.
Second, we use Rebar Thread Cutting machine to process thread on the forged end of rebar;
Third,we use Upset parallel thread coupler to abuting joint two threaded ends of rebar .
1. Product Description
HDCJ-32S automatic double-cylinder rebar upsetting machine is used to enlarge the diameter of the rebar head with high pressure, then make thread on it, which can make effective cross section of the thread bigger than the base rebar. It can improve the quality of the joint and make joint’s compression and tensile strength bigger than the base rebar. The machine is used in high quality rebar splicing of national projects such as bridge and subway.
2. Features
The machine is easy to operate, with high quality and high speed, and not effected by environment. It is used in the forgoing processing of HRB335 and HRB400 rebar with diameter of 14-40mm.

5. Operation
1- Installation
After the mold is installed, reset the stroke limiting bracket. Adjust the travel limit screw so that the stroke control in 15mm, insert the test steel bar to the top of the mold center hole press automation button. After the processing of the work-piece, measurement it. If failed, then adjust stroke limit screw to make the trip gradually increased, until processing of qualified products.
2- Safety operation rules
1. Workers have to be trained and tested OK then can work.
2. Before operation with rebar, first running the machine 2-3 mins without processing, if it is running normally the process.
3. The feeding head of head should be plain and straight.
4. Before processing the rebar, the machine should be reset and then process
to ensure the same processing.
5. The processing rebar can not have the transverse cracks, when the equipment break down should be eliminated timely.
6. Oil should be 68# hydraulic oil.
7. Workers should obey the safety rules
3- Machine Failure and Exclusion
Trouble phenomenon | Reason | Method of exclusion |
No action of cylinder | Motor reverse | Swap two-phase power supply |
Electromagnetic spill valve failure | Replace the electromagnetic spill | |
Low oil level | Add hydraulic oil | |
Residual air in cylinder | Empty ru
