High Speed Rebar Upsetting Machine , Three Phase Steel Rebar Forging Machine
   
    1. Product Details
     
       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.
 
       3. Main Technical Standard
 

 
       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
 
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 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.
