Technical Proposal & Quotation For
HG 2.5” Front prepare machine
I. Summary
2.5” Include uncoiler,straight head and pinch leveling machine ,shear and welder, spiral accumulator.
II. Basic Conditions:
2.1 Steel pipe specification
2.11 Round Pipe: φ25—φ63.5mm Thickness:1-3mm
2.12 Square Pipe: 20X20-50X50mm Thickness: 1-3mm
2.2 Strip steel
2.2.1 Strip steel width: 70mm-200mm Strip steel thickness:1-3mm
2.2.2 Galvanized coils and HRC: δb≤500Mpa σs≤355MPa
2.2.3 Steel strip coil: Inner diameter: Φ508mm (customer confirm finally)
Outer diameter: Φ1000mm-2000mm (customer confirm finally)
2.2.4 Steel strip weight: Max 4.0T
2.3 Electric installed capacity: approximately 650KW Power supply: 380V, 60Hz (customer confirm finally)
III. Equipment makeup and main parameters of single unit:
This equipment has double cone clamping . The end opener has press roller,. The uncoiler cones head clamp the steel coil with the function of cone. Then press roller of the end opener moves down to tighten steel coil. The uncoiler cone rotating, the ends opener peeler swings up and close to the coil. When steel coil head rotate to the peeler,
Inner diameter of the strip steel:Φ 508mm (the buyer supply finally)
Outer diameter of the strip steel:Φ max=2000mm
Strip steel width: 70mm-200mm
Strip steel thickness: 1-3mm
The maximum weight of the strip steel: 4.0T
Hydraulic expansion
Pneumatic break
2.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:Ф140mm
leveling roll diameter:Ф110mm
pinch and leveling motor:15kw
3.Shear and Welder
Function:
It is used to parallel cut the tail of the steel strip, which has just gone into the accumulator, and the head of the strip coming out of uncoiler, and then weld them together.
Structure:
Hydraulic Shearing and manual welding Strip steel width: 70mm-200mm
Strip steel thickness: 1-3mm
Centering way: manual
4. Spiral accumulator
| |
- This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.
- 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
