Hydraulic Oil Automatic Rebar Coupler Machine , Double Cylinder Rebar Upsetting Machine
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. Rebar Upsetting Forging Machine
A. Operation is simple, do not need professional technicians, fast speed.
B. It can process HRB335 and HRB400 steel bars with diameters ranging from 16-40mm.
C. The actual cross-sectional area after processing thread is greater than the original item, greatly improve the tensile strength of the joint.
D. High efficiency, can produce 300-500 wire head per machine-team.
E. Environmental protection, safety, economy, less investment, low cost.

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 run 3-5min | |
| The cylinder can only run in one direction or the oil cylinder nonstop | Solenoid valve Cards | Find professional repair person |
| Die of steel | Die wear | Change mold |
| Small pressure | Professional Surge | |
| Mold cracking | Too much pressure | Replacement of mold, professional regulator |
| Upsetting head is not full | Screw stroke wrong location | Adjustment |
6. Usage Method
The preparations before process1.1 To connect the power line. The power supply is three-phase four-wire. It must be connected with ground wire before power on.
1.2 The oil tank fills with enough hydraulic oil. The oil weight is about 75 litre. The oil level can be observed in the oil level gauge.
1.3 Check all parts to see if they are flexible or not.
No-load test2.1 Connect the power line and press the start button. To observe the whether the directi
