A complete metal slitting machine (or production line) typically consists of a series of units arranged according to the specific processing workflow, with the slitting main unit serving as its core. The overall structural composition is as follows:
A standard production line primarily comprises core components such as a coil loading car, uncoiler, leveler (or rough leveler), slitting main unit, scrap edge winder, tension station (or tensioner), recoiler, and unloading device (discharge car). Some high-end or comprehensive production lines may also incorporate auxiliary equipment, such as a coil head shear, side guiding device, looping pit bridge, and auxiliary supports.
The electrical control system (typically a PLC-based numerical control system) and the hydraulic system constitute the control and power core of the entire machine.
The slitting main unit is the critical component of the slitting machine, responsible for the precise shearing of the material. Its main structure consists of a welded base, fixed and movable housings (uprights), and a slide assembly [1]. The cutter shafts are manufactured from forged steel that has undergone quenching and tempering treatment; they work in conjunction with a worm gear synchronous lifting system to achieve micron-level adjustment precision, and utilize left- and right-handed nuts to lock the cutting tools in place for the slitting operation [2].
