Model: 1650 Stop Shear Cut-to-Length Line with 4HI Leveler
The XIONGJIN 1650 Stop Shear Cut-to-Length Line is designed to convert steel coil into leveled sheets at programmed lengths. The supplied reference configuration combines coil handling, a 19-roll 4HI precision leveler, NC feeding and length setting, a stop shear, conveyor and automatic stacking equipment for stable sheet processing.
Product Overview
This line is suited to cold-rolled sheet, galvanized sheet, pickled general-purpose sheet and automotive steel sheet within the material range of the supplied technical quotation. It brings the coil from storage and decoiling through leveling, side guiding, NC measurement, stop-shear cutting, conveying and orderly sheet stacking.

Major Equipment
4HI Precision Leveler
The reference 4HI leveler uses 19 leveling rolls with a four-high support structure. Its work rolls and reinforcing rolls are designed for precision leveling; the quotation specifies independent roller adjustment and centralized lubrication. A 6HI leveler can be configured where the material, thickness band and flatness target call for a higher-support arrangement.
NC Measuring and Side Guide
The side-guide correction device positions the sheet across its width, while the NC feeding and length-setting unit measures material and sends the programmed cut length to the shear. The supplied reference lists a closed-loop measuring wheel, encoder feedback, five leveling rolls, four feeding rolls and a pair of length-setting rolls.
Stop Shear
The stop-shear section cuts material to the programmed length following NC measurement. The reference equipment uses a heavy-duty crankshaft cutting mechanism, four-sided blades, centralized forced lubrication, water cooling and touchscreen-controlled blade-gap adjustment.
Conveyor, Stacker and Lift Table
After shearing, the PVC belt conveyor transfers sheets without direct metal-to-metal handling. The automatic stacker combines pneumatic and hydraulic motion, with air-cushion support and photoelectric lift-table control. The stacker reference supports sheets up to 4,000 mm long and a 5,000 kg maximum load.
Reference Layout
The layout below is a reference drawing supplied with the stop-shear cut-to-length documentation. It illustrates the material flow from decoiling through leveling, loop storage, NC measurement, stop-shear cutting, conveying and stacking. Foundation dimensions, pit requirements, service positions and the final layout must be confirmed for the project site.
Project Configuration
XIONGJIN can configure the coil car, decoiler, 4HI or optional 6HI leveler, length-setting system, stop shear, stacking method and downstream handling around the customer’s coil grade, surface requirements, output length and available floor space.
