Hydraulic Steel Bar Forging Rebar Processing Machine Lightweight Fast Speed
Rebar Upsetting Forging Machine is mainly used for construction of ribbed steel bar rolling straight thread head, is an important equipment of steel connection.
Rebar Upsetting Forging Machine use the cold heading principle to make the steel end for plastic deformation, diameter increased 16-32mm, and then processing thread.
Features
1. Operation is simple, do not need professional technicians, fast speed.
2. It can process HRB335 and HRB400 steel bars with diameters ranging from 16-40mm.
3. The actual cross-sectional area after processing thread is greater than the original item, greatly improve the tensile strength of the joint.
4. High efficiency, can produce 300-500 wire head per machine-team. 5.Environmental protection, safety, economy, less investment, low cost.
Technical Parameter
1. Process Range: rebar of Φ16—Φ32.
2. Motor Power: Y132M-4 7.5KW
3. Power Supply: three-phase four-wire 50HZ
4. Hydraulic Pump: 10MCY14-1B 31.5MPa
5. Hydraulic Oil: 68# hydraulic oil
6. Weight and Size: 1000KG 1250×850×1650mm
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 Methods
- 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.
