What Are The Types Of Slitting Machines?

1. Parallel blade shearing machine. The two blades of this shear are parallel to each other. It is usually used to transversely shear bloom billets (square, slab) and other square and rectangular cross-section steel billets, so it is also called billet shearing machine. This type of shearing machine sometimes also uses two forming blades to cold shear rolled parts (such as round tube blanks and small round steel, etc.). At this time, the shape of the blade is adapted to the cross-sectional shape of the sheared and rolled parts.
2. Oblique blade shearing machine. The two blades of this shearing machine, the upper blade is inclined and the lower blade is horizontal, are positioned at a certain angle to each other. The inclination of the upper blade is 1° to 6°. This kind of shearing machine is commonly used for cold shearing and hot shearing of steel plates, strips, thin slabs and welded pipe blanks. Sometimes it is also used to cut small steel products in bundles.
When rolling hollow window materials, an inclined blade shear is often used to cut the head and tail of the strip (when the strip is not cut at the head and tail) for welding into large coils of strip.
The oblique blade shearing machine makes the upper blade inclined and the lower blade horizontal. Its purpose is to reduce the shear contact length with the sheared piece, thereby reducing the shearing force and reducing the size of the shearing machine. , and simplify the structure. The main parameters of the oblique blade shearing machine are: maximum shearing force, blade inclination angle, blade length and number of shears. These parameters are determined based on the dimensions and mechanical properties of the rolled piece.
