Technical Proposal For
HG 5” Front prepare machine
1. double cone Hydraulic Uncoiler
The uncoiler is of the structure of double cone. It contains two main parts: main body and the fixed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.hydraulic expanding and Pneumatic driving
| coil out diameter | Φ2000-2200mm |
| coil inner diameter | Φ480-610mm |
| strip width | 200-400mm |
| strip width | 1-5mm |
| strip weight | Max10.0T |
| expand type | hydraulic expand,sliding block structure |
| break | Pneumatic drive,2 pcs disc break |
- straight head and pinch leveling machine
This unit is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place.
straight head motor power :AC1.5KW
processing pressure:7Mpa
The leveling unit with 2 roll pinch and 5 roll leveling.
pinch roll diameter:Ф180mm
leveling roll diameter:Ф120mm
pinch and leveling motor:15kw
3) hydraulic shear and manual welder
Shear and welder is used to cut the irregular ends of the strips and then connect the strips by welding..
| shear width | 200-400mm |
| welding thickness | 1-5mm |
| shear type | hydraulic shear |
| Compression way | hydraulic |
| welding type | auto |
| blade material | H13 |
| hydraulic pressure | 10MPA |
| air pressure | 0.5MPa |
| working cycle | Max.300 s |
4) spiral accumulator
This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.
feeding device
It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.
Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.
Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.
working style: fixed circle
diameter :5.0M
advantage:storage more material,no strike to strip steel suface
steel coil thickness:1-5mm;
width:200-400mm
carry material going velocity:Vmax=120m/min
directly electric motor power of the press & carry:30KW
the electric motor of the accumulator frame : 55KW
