11850 Decoil-Straighten-Feeding Production Line

Overview
The 1850 Decoil-Straighten-Feeding Production Line is a heavy-duty, automated material handling system designed for the stamping industry. With a maximum material width capacity of 1850 mm, this line is engineered to process large coils of metal sheet, delivering flat, stress-relieved, and precisely measured blanks to a stamping press. It is specifically suited for high-precision, high-volume production in the Automotive, Aerospace, and Defence sectors.
Process Flow & Key Components
The line operates in a continuous sequence, transforming a raw coiled strip into a cut-to-length blank ready for stamping. Based on the provided layout, the system consists of the following major stations:

1. Decoil (Uncoiler)

Function: Holds and unwinds the raw metal coil.
Details: Located at the far left (spanning approx. 1891.36 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. Introduce & Cut

Function: Initial processing and scrap removal.
Details: Spanning approximately 825 mm (with sub-dimensions of 747.5 mm and 140 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. 1450 mm, with a working width of 792.5 mm and a 400 mm section). It utilizes a multi-roll cassette (typically 9, 11, or 13 rolls) to eliminate coil set, cross-bow, and edge waves. The straightener ensures the material is perfectly flat before feeding, which is essential for high-quality stamping and dimensional accuracy.

4. Loop Control

Function: Buffering and tension regulation.
Details: This tall vertical tower (spanning 2100 mm) acts as a 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.

5. Feed & Shear

Function: Precision feeding and final cut-to-length.
Details: The final section (spanning 1351.86 mm, plus 550 mm and 1530 mm for the shear and exit conveyor) 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. A 200 mm section at the end likely refers to a discharge conveyor or chute.
Key Features & Benefits
High Rigidity: Designed to handle thick, wide materials (up to 1850 mm) without deflection, ensuring long tool life and consistent quality.
Automation Ready: The loop control and servo feeding system allow for seamless integration with robotic or transfer press lines.
Versatility: Suitable for processing various metals including steel, aluminum, and high-strength alloys used in automotive structural parts and aerospace components.
Precision: The straightening and servo feeding combination guarantees flatness and length tolerances critical for defence and aerospace applications.
