Description

USED THREE-ROLLER CALENDER. BRAND FACCIN, MODEL ASI/M, YEAR OF CONSTRUCTION 1998.

Technical Data Sheet: FACCIN ASI/M THREE-ROLLER CALENDER (1998)

Brand: Faccin
Model: ASI/M
Year of Construction: 1998
Machine Type: Used three-roll calender

1. General Description

The Faccin ASI/M plate bending machine, built in 1998, is a machine tool used to bend sheet metal. This three-roll plate bending machine is suitable for industrial applications in sectors such as metal fabrication, the production of tanks, pipes, and other curved structures. The machine is designed to operate with precision and reliability, even after years of use.

2. Composition and Main Parts

Rollers:
- Number of rollers: 3 (one upper and two lower).
- Roller material: Hardened steel to resist wear and maintain precision over time.
- Function: The upper roller is adjustable to determine the bending radius, while the two lower rollers support and advance the sheet metal.
Chassis:
- High-strength steel load-bearing structure, designed to withstand stress during processing without deforming.
Regulation system:
- Mechanical or hydraulic: Adjusts the position of the upper roller and, in some models, also the lower rollers, to suit the sheet metal thickness and the desired bending radius.
Engine and transmission:
- Motor: Electric, with adequate power to ensure uniform bending even on thick sheet metal.
- Transmission: Gears and chains that transfer motion from the engine to the rollers.
Control Panel:
- It allows you to set operating parameters, such as the sheet metal feed speed and the adjustment of the roller position.

3. Operation

The Faccin ASI/M plate bending machine works by plastically deforming the sheet metal, which is passed between rollers. The upper roller exerts pressure on the sheet metal, which bends depending on the distance between the rollers and the applied pressure.

4. Workable Materials

This calender is designed to process a variety of metal materials, including:

Carbon steel
Stainless steel
Aluminum
Copper
Metallic alloys

5. Mathematical Formulas for Sheet Metal Deformation

To calculate the bending radius and other characteristics of sheet metal deformation, the following formulas can be used:

Minimum bending radius (R):
$\frac{E \cdot t}{2 \cdot \sigma_{yield}}$
Where:
- $R$ = Radius of curvature
- $E$ = Modulus of elasticity of the material
- $t$ = Thickness of the sheet metal
- $σyield\sigma_{yield}$ $σ$ $_{y}$ $_{i}$ $_{e}$ $_{l}$ $_{d}$ =
Minimum obtainable internal radius (R_{\text{min}}):
$Rmin=D−D2−4⋅t⋅d2R_{\text{min}} = \frac{D - \sqrt{D^2 - 4 \cdot t \cdot d}}{2}$
Where:
- $D$ = Diameter of the upper roller
- $d$ = Diameter of the lower rollers
- $t$ = Thickness of the sheet metal

These formulas allow you to design the curvature in such a way as to avoid excessive deformations or damage to the material.

6. How to Choose a Good Used Item

When purchasing a used Faccin grille, it is essential to check:

Condition of the rollers: They must be free of excessive wear, scratches, or dents, and their surface must be uniform.
Adjustment System: Check that the roller adjustment system works properly, without oil leaks or difficulty in movement.
Engine and transmission: The engine must operate without abnormal overheating and the transmission must be free of abnormal play or noise.
Maintenance Records: Request the maintenance log to ensure that the machine has been properly cared for over time.

7. Maintenance

To ensure the longevity and efficiency of the grille, it is necessary:

Regular Lubrication: Lubricate rollers and moving parts to prevent wear and maintain smooth operation.
Checking the hydraulic system (if equipped): Check the oil level and for any leaks.
Periodic cleaning: Remove metal residue and dust to prevent them from negatively affecting operation.
Checking screws and bolts: Make sure all components are securely fastened and tightened to avoid vibrations and damage.

8. Using the Grille

To use the grille correctly:

Setup: Adjust the rollers to the sheet thickness and desired bending radius.
Start-up: Insert the sheet metal between the rollers and start the machine, checking the curvature during operation.
Checking the result: Make sure that the sheet metal has reached the desired curvature and that there are no visible defects.
Removing the piece: Once the bending is complete, remove the sheet metal and check that it conforms to the required specifications.

9. Why It's Worth Buying Used

Buying a used 1998 Faccin ASI/M grille can offer several advantages:

Savings: A used machine costs less than a new one, allowing for a lower initial investment.
Limited depreciation: Quality machine tools such as those from Faccin maintain their value over time.
Reliability: Faccin calenders are known for their durability and sturdiness, so a well-maintained machine can offer high performance even after many years.
Immediate availability: Used machines are generally ready for use, avoiding the waiting times required for the production and delivery of a new one.

Conclusion

The 1998 Faccin ASI/M three-roll plate bending machine is a solid and versatile machine, ideal for sheet metal processing in many industrial applications. If properly maintained, it can provide many years of reliable service, making purchasing a used model a cost-effective and effective choice for many businesses.
