Simple Slitter And Cut To Length Machine For Galvanized Coil Standard

Simple Slitter And Cut To Length Machine

A combined coil processing line that slits a wide coil into narrow strips and cuts flat sheets to length on the same machine.

• Two functions in one line: longitudinal slitting with rewinding, and cut to length with stacking.
• Coil weight up to 12 t, material thickness 0.3-1 mm in galvanized steel.
• Feeding width 1550 mm and cutting width 600-1550 mm, at a cutting speed of 0-20 m/min.
• 2-10 slitting lines to suit the strip widths required.
• Leveling rollers 80 mm solid; slitting blade shaft in 40Cr at 140 mm; Cr12MoV slitting and cutting blades.
• 11 kW rated power, PLC control, electrical motor cutting, 2 years warranty.

Product Overview

The line takes a coil at one end and delivers either narrow strips wound on a rewinder or flat sheets stacked on the run out table, so a manufacturer can produce strip for tube and pipe forming and cut sheets for stamping without buying two separate lines.

Uncoiling, leveling, longitudinal slitting, rewinding, cut to length and stacking are carried out along one bed with a single control system. The line is described by the supplier as about 15 m long, and the layout drawing shows the decoiler, looper, side guide device, straightener, slitting and cutting units, sheet car and stacker arranged in sequence.

Key Features

Two Machines In One Line

Slitting and cut to length are combined in a single line, so the same coil is either slit into narrow strips on the rewinder or leveled and cut to sheets on the run out table. One operator, one control system and one machine bed cover both jobs.

Compact Arrangement

Because the two processes share the uncoiler, the leveling unit and the bed, the combined line occupies far less floor space than a separate slitting line and a separate cut to length line, and the supplier describes the working length as about 15 m.

Flexible Production Switching

The line can be run in slitting mode to produce narrow strip for tube making, or in cut to length mode to produce flat sheets for stamping, so a workshop can serve different downstream products from the same coil stock instead of holding two dedicated machines.

12 Ton Coil Capacity

The decoiler and the coil car are rated for coils up to 12 t, with a material feeding width of 1550 mm, which covers the standard coil sizes used for galvanized sheet processing.

Cr12MoV Slitting And Cutting Blades

Both the slitting blades and the cutting blade are made of Cr12MoV tool steel, and the slitting shaft is a 40Cr forging at 140 mm diameter, giving the blade set the rigidity needed to hold strip width tolerances in long production runs.

Leveling Unit With 80 mm Solid Rollers

The leveling rollers are 80 mm solid shafts, arranged in a stack that removes coil set and cross bow before the strip reaches either the slitting unit or the shear, which is what keeps the cut sheets flat.

2 To 10 Slitting Lines

The number of slitting lines is set between 2 and 10 to match the strip widths required, so the blade and spacer arrangement on the slitting shaft is configured for the job rather than fixed.

PLC Control And Electrical Cutting

A PLC controls the line, with the cut length set from the panel and cutting carried out by an electrical motor shear. Video outgoing inspection and a machinery test report are provided, and the machine carries a 2 year warranty.

Technical Specifications

Production Line Layout

The supplier layout drawing labels the following units along the line. The coil is carried in on the entry coil car, uncoiled and leveled, then either slit and rewound or cut to length and stacked.

• Decoiler with hydraulic lifting table and entry coil car.
• Looper and side guide device.
• 4-h straightener and servo straightening machine.
• Slitting unit with blade shafts and spacer collars, and the rewinder for slit strip.
• Cutting machine with electrical motor cutting.
• Transition table, exit sheet car and pneumatic stacker.

Machine Structure

The line is built on cream painted welded frames with the conveyor, the slitting head, the rewinder and the guards arranged along the bed.

The coil is loaded on the decoiler mandrel, with the hydraulic lifting table and coil car positioning the coil on the shaft before the coil is opened and fed into the line.

The leveling unit runs a stack of 80 mm solid rollers with adjustment screws above, removing coil set before the strip is either slit or cut to length.

In the slitting head the strip passes through the slitting shafts, and the narrow strips leave the blades and run out over the exit table.

The slitting shaft carries the Cr12MoV slitting rings separated by spacer collars, which is how the strip width is set, with the blade shaft in 40Cr at 140 mm diameter.

The slit strips are wound on the rewinder drum at the exit end of the line, ready for the downstream tube or pipe mill.

Customization And Supply Scope

• Supply scope: 1 set, sold as a single item.
• Customization ability: minor customization, drawing-based customization, sample-based customization and full customization.
• Coil weight, cutting width, number of slitting lines, material thickness and voltage are set to the requirement.
• Video outgoing-inspection and a machinery test report are provided with the machine.

FAQ

What does the machine do?

It slits a wide coil into narrow strips that are rewound on the rewinder, and it also levels and cuts the strip into flat sheets of a set length which are stacked on the run out table.

What material and thickness can it process?

Galvanized steel from 0.3 mm to 1 mm thick.

What coil and strip sizes are supported?

Coils up to 12 t, a material feeding width of 1550 mm, a cutting width from 600 mm to 1550 mm and 2 to 10 slitting lines depending on the strip widths required.

How is the cut length controlled?

The line is controlled by PLC, cutting is carried out by an electrical motor shear, and the cutting speed range is 0-20 m/min.

How long does production take?

45 days for an order of 1 to 5 sets; for more than 5 sets the lead time is to be negotiated.

What warranty and inspection are provided?

The machine carries a 2 year warranty, and a video outgoing-inspection and a machinery test report are supplied with the shipment.
