Gain 25% productivity in your workshop: Or the benefit of sheet metal levelling before use in bending, welding and rolling
In the metallurgical industry, the quality and precision of bending, welding and rolling operations are essential to guarantee the durability and efficiency of the structures manufactured. Sheet metal leveling, a process often underestimated or limited to its use before deburring, plays a crucial role in optimizing these processes. This article explores the importance of leveling sheet metal before use, highlighting the benefits in terms of consistent results and increased productivity.
What is Sheet Metal levelling/Straightening?
Sheet metal levelling is a mechanical operation aimed at eliminating undulations, bumps and residual tensions present on metal surfaces. This process produces perfectly flat and uniform sheets, ready for use in subsequent manufacturing operations.
Homogeneity of Results
One of the main advantages of sheet metal levelling is the improvement in the uniformity of results in bending, welding and rolling operations.
1. Folding
- Uniformity of Bending Angles: Levelling ensures a flat and regular surface, allowing precise and uniform bending angles along the entire length of the sheet.
- Reduction of Defects: By eliminating undulations and tensions, levelling reduces the risk of cracks and deformation during folding and limits corrections or rework.
2. Welding
- Precise Alignment: Planed sheets align more easily, ensuring precise and consistent welds.
- Less Distortion: Reducing residual stress minimizes distortion during welding, improving the quality of welded joints and the time spent by the operator.
3. Rolling
- Precise and Uniform Shapes: Planed sheets make it possible to obtain regular and precise rolled shapes, without unexpected variations.
- Reduction in Rework: The initial flatness of the sheets reduces the need for post-rolling corrections, saving time and resources.
Improved Productivity
The homogeneity of results obtained thanks to sheet metal levelling results in a notable increase in productivity in manufacturing workshops (Up to 25% measured)
1. Reduction of Rejects
- Fewer Defective Parts: Improving the quality of bent, welded and rolled parts reduces rejection rates, minimizing material loss and associated costs.
2. Optimization of Production Times
- Fewer Reworks Required: A flat, homogeneous sheet requires fewer reworks and corrections, speeding up production cycles.
- Efficient Planning: The consistency of performance of planed sheets allows more precise and efficient planning of operations, reducing downtime.
3. Increased Tool Life
- Reduced Wear: Bending, welding and rolling tools undergo less stress with planed sheets, extending their life and reducing maintenance costs.
Levelling sheet metal before bending, welding and rolling operations is an essential step to guarantee consistent results and improve productivity. By eliminating ripples and residual stress, levelling helps produce consistently high-quality parts, while optimizing production times and reducing costs. For manufacturing workshops concerned with efficiency and performance, sheet metal levelling represents an essential and beneficial strategy.Voir les gammes de machines :
