1600 Laser Blanking Production Line

1600 Laser Blanking Production Line

Overview

The 1600 Laser Blanking Production Line is an advanced, high-precision material handling system designed to feed metal coils directly into a laser cutting machine. With a maximum material width capacity of 1600 mm, this line integrates traditional coil processing (decoupling, leveling, and feeding) with modern laser cutting technology. It is engineered for high-speed, flexible production, making it ideal for industries requiring complex geometries and high-quality cut edges.
Process Flow & Key Components
The line operates in a continuous sequence, transforming a raw coiled strip into a flat, precisely positioned sheet ready for laser cutting. Based on the provided layout (total length of 14,540 mm), the system consists of the following major stations:

1.Decoil (Uncoiler)

2.Function: Holds and unwinds the raw metal coil.
Details: Located at the far left (spanning approx. 1710 mm + 2010 mm), this heavy-duty decoiler supports large coil weights. It features a hydraulic expansion mandrel and a coil car for safe loading. The decoiler pays off the strip, which then enters the next stage.

2. Intro/Cut

Function: Initial processing and scrap removal.
Details: Spanning approximately 1062 mm (with a sub-dimension of 748 mm), this section includes a peeler/threading table to guide the strip. The "Cut" mechanism (likely a shear or scrap cutter) removes the irregular leading end of the coil before it enters the straightener, ensuring smooth engagement.

3. Straighten

Function: Leveling and stress-relieving the metal strip.
Details: This is a critical precision unit (spanning approx. 1480 mm). It utilizes a multi-roll cassette to eliminate coil set, cross-bow, and edge waves. The straightener ensures the material is perfectly flat before feeding, which is essential for accurate laser cutting and dimensional consistency.

4. Loop Control

Function: Buffering and tension regulation.
Details: This long horizontal section (spanning 5190 mm) acts as an accumulator. It creates a free loop of material between the straightener and the feeder. This loop isolates the continuous straightening process from the intermittent start-stop motion of the feed and shear unit, preventing material slippage or deformation during high-speed feeding. The loop pit allows for significant material storage, enabling the line to run continuously.

5. Feed/Shear

Function: Precision feeding and final cut-to-length.
Details: The final section (spanning 1740 mm + 600 mm) consists of a high-precision servo feeder and a heavy-duty shear. The servo feeder measures the exact length of the strip, while the shear cuts the material into precise blanks or sheets. These sheets are then fed directly into the Laser Cutting Machine (labeled in the drawing) for final processing.
Key Features & Benefits
High Rigidity: Designed to handle thick, wide materials (up to 1600 mm) without deflection, ensuring long tool life and consistent quality.
Automation Ready: The loop control and servo feeding system allow for seamless integration with laser cutting machines, enabling fully automated production.
Versatility: Suitable for processing various metals including steel, aluminum, and high-strength alloys used in automotive structural parts, aerospace components, and building materials.
Precision: The straightening and servo feeding combination guarantees flatness and length tolerances critical for high-quality laser cutting.
Flexibility: Laser cutting allows for complex shapes and contours without the need for dedicated dies, making this line ideal for prototyping and low-to-medium volume production.
