The usage, characteristics and structure of the rotary slitting machine

Since the blades configured in the disc slitting machine are rotating discs, they can continuously cut steel plates and strips longitudinally during work. Under normal circumstances, the disc slitting machine is set on the finishing line to trim and cut the longitudinal edges of the moving steel plate or cut into narrow strips. According to its use, it can be divided into shearing discs. Disc shears for cutting and cutting strip steel.

In fact, in the disc slitting machine, all the blades in the disc cutter used to cut the edge of the plate are fixed on a separate transmission shaft in the form of a cantilever, and the number of blades is two pairs. This kind of production equipment is mainly used for thick plate finishing lines, coil cross-cutting units and continuous pickling units. The disc shears for cutting strip steel are used in the coil slitting unit, continuous annealing and zinc crossing units and other operating lines.

That is to say, the use of this production line is mainly to slit the coil into narrow strip products of certain specifications, which are mainly used as blanks for welded pipes and rims. The number of blades of this disc cutter is many pairs. Generally, the blades are fixed on two common moving shafts, and a few disc blades are fixed on independent transmission shafts.

At present, when the overall design is being carried out, corresponding improvements can be made to the structural composition of this slitting unit. The nose stick can design its main shaft drive system, blade lateral adjustment mechanism, especially the transmission part of each mechanism, so as to improve the use performance of the equipment.

From the perspective of structural composition, generally in the disc slitting machine equipment, the main mechanical components include: cutter head rotation transmission system, cutter head radial adjustment and blade lateral adjustment, shear width adjustment, etc. The adjustment of the cutting width is actually the adjustment of the distance of the rack.
