Application of Blanking Lines in Automotive Industry

In the automotive industry, blanking lines are used to produce sheets with consistent dimensions and stable quality, enabling efficient stamping production. Coil is decoiled and leveled to form a flat strip. The strip is fed for pressing or laser cutting, ultimately forming sheets. Next, we discuss the features of blanks in the automotive industry and the blanking lines used.

Features of Automotive Stamping Blanks

1. Multiple Specifications

Automotive components come in a wide variety and varying sizes, with some large parts (such as door panels and hoods) having particularly large dimensions.

2. Multiple Shapes

To facilitate stamping or meet structural design requirements, some blanks have complex contours.

Press Blanking Line

Overview

(The press blanking line uses a blanking die to cut the strip.)

The press blanking line punches or shears the strip using dies to obtain the desired sheets. The sheet can be rectangular or a simple irregular shape.

Features

1. High blanking speed and high production efficiency.

2. Different dies are used to produce sheets of different shapes. When changing production, it is necessary to stop the machine to replace the dies.

3. Storing multiple dies requires more factory space, and the die maintenance work will also increase.

Laser Blanking Line

Overview

(A laser blanking line can be configured with multiple laser cutting machines.)

The laser blanking line uses laser cutting to cut strips into sheets. It can produce various shapes without being limited by dies.

Features

1. No dies are required. Changing the cutting program is enough to produce different products, improving efficiency.

2. Compared to die stamping, the cutting program can achieve a compact cutting layout, maximizing material utilization.

3. Sheets processed by laser cutting typically have burr-free edges and high quality. Compared with die stamping, laser cutting applies less external force to the strip, making it more friendly for thin or easily damaged materials.
