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
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
3. Main Technical Parameter
Rebar of Φ16—Φ32
Three-phase four-wire 50HZ
68# hydraulic oil
The machine include machine tool, press oil cylinder, forward oil
cylinder, main body, mould and upset head, electrical control
system, hydraulic system.
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
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
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 process
1.1 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
1.3 Check all parts to see if they are flexible or not.
2.1 Connect the power line and press the start button. To observe
the whether the direction of the motor turn is correct. If not
correct, change two phases of the three phases.
2.2 To operate the buttons to see the actions of each button
whether are right or not. (note: finally observe the automatic
- The adjustments of machine
3.1 According to rebar diameter which needs process to choose
suitable modal before process.
3.2 Change the modal: first to take off the range limit holder,
move the cylinder back button to the starting position. Press the
cylinder up button to let the lower pressure cylinder rise to the
starting position. To remove the screws in the both sides of the
upper modal and then the upper modal can be taken off from the
middle. Then remove the lower modal and the end pressing plate and
the lower modal can be taken off from the middle. Will be
consistent with the diameter of the thread steel mold, in
accordance with the above operation of the reverse operation can be
installed. To observe the upper mold operation whether is flexible
or not. If not, it can be remove to grind the sliding surface.
