Flying Shear Cut-to-Length Lines

1650mm Flying Shear Cut-to-Length Line

1650mm coil-to-sheet production

1650mm flying shear cut-to-length line for stable, high-output production.

Configured for wider-coil sheet production where cutting coordination, leveling quality, material flow, and repeatable stacking are critical.

The production line coordinates uncoiling, guiding, leveling, measuring, moving shear cutting, conveying, and stacking. The equipment configuration is selected according to material grade, coil dimensions, finished sheet requirements, production speed, and site conditions.

Project-specific technical values are confirmed through engineering review rather than presented as one fixed specification for every application.

  • Coordinated moving shear operation
  • Stable material flow through the line
  • Configuration based on finished sheet requirements

Working principle

How the 1650mm Flying Shear Cut-to-Length Line Works

The 1650mm line is designed to coordinate wider-coil handling with leveling, length measurement, dynamic shearing, conveying, and stacking. Encoder feedback and the motion controller calculate the cutting point, while the shear carriage follows the strip during the cutting stroke. After the cut, the carriage returns and prepares for the next command as the finished sheet moves toward the stacking system.

1650mm Wide-Coil Production Process

Wider and heavier coils require coordinated material handling, structural stiffness, drive selection, and safe access throughout the line.

  1. Coil receivingVerify coil size, weight, material grade, and surface before loading.
  2. Coil loadingTransfer and center the coil on the payoff equipment using the selected loading system.
  3. Controlled uncoilingManage strip release and entry conditions for stable downstream processing.
  4. Guiding and levelingMaintain centerline control and improve flatness across the wider strip.
  5. Length trackingMeasure strip travel and issue the cutting command from the production recipe.
  6. Flying shear cycleAccelerate, synchronize, cut, and return the shear carriage under motion control.
  7. Wide-sheet conveyingSupport the sheet and maintain controlled transfer after cutting.
  8. Stacking and unloadingAlign, collect, and remove finished sheets using the specified handling arrangement.

Wide-Coil Equipment and Line Control

The 1650mm configuration is reviewed as a complete production system rather than a collection of isolated machines.

Coil car and uncoiler

Handle the confirmed coil dimensions and loading weight with controlled alignment.

Entry guide and heavy leveler

Support stable strip tracking and flatness improvement across the working width.

Measuring system and flying shear

Coordinate encoder signals, drive response, cutting motion, and production recipes.

Conveyor and stacking system

Support wider sheets, controlled spacing, alignment, collection, and discharge.

PLC, HMI, servo, and diagnostics

Synchronize the line and provide recipe, alarm, status, and maintenance information.

Structure and safety equipment

Match foundations, guarding, access platforms, interlocks, and emergency stops to the site.

1650mm Materials and Applications

The 1650mm series is suited to wider-sheet production where coil handling, leveling performance, moving mass, material flow, and repeatable stacking must be considered together.

  • Cold-rolled, galvanized, stainless, color-coated, and aluminum coil within the engineered operating envelope
  • Construction panels, industrial enclosures, appliance and automotive-related sheet, service-center blanks, and general metal processing
  • Projects requiring wider coil capacity and a coordinated high-output production workflow

What Determines the Final 1650mm Configuration

For a wide-coil line, the highest width, thickness, coil weight, and speed should not be assumed to operate simultaneously. Engineering selection is based on the complete production envelope.

  • Material grade, yield strength, surface quality, and permitted marking
  • Normal and maximum combinations of coil width and thickness
  • Maximum coil weight, coil diameters, loading frequency, and handling equipment
  • Finished sheet length, flatness, diagonal, cutting tolerance, and stack weight
  • Target speed and output, drive power, foundation, line length, access, and maintenance space

1650mm Flying Shear Line FAQ

Can the 1650mm line run at 90 m/min with every material?

No. Line speed is confirmed from material strength, thickness, width, cut length, required quality, stacking, and the selected equipment.

Why is workshop information required?

The line layout depends on foundation, available length and width, crane or forklift access, coil flow, finished-sheet removal, utilities, and maintenance clearances.

How is wide-sheet flatness handled?

Leveler roll arrangement, stiffness, adjustment, material condition, and operating parameters are selected after reviewing the required flatness and working range.

What should be sent for a technical proposal?

Send representative coil specifications, finished sheet requirements, output target, layout drawing, utility information, and any special surface or handling requirements.
