Hydraulic Oil Automatic Rebar Coupler Machine , Double Cylinder Rebar Upsetting Machine

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.

3. Main Technical Parameter

Rebar of Φ16—Φ32

Motor Power

Y132M-4 7.5KW

Power Supply

Three-phase four-wire 50HZ

Hydraulic Pump

10MCY14-1B 31.5MPa

4. Structure

The machine include machine tool, press oil cylinder, forward oil cylinder, main body, mould and upset head, electrical control system, hydraulic system.

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

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 gauge.

1.3 Check all parts to see if they are flexible or not.

  • No-load test

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 operation.)

  • 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.
