3 Classification and accuracy class
3.1 Classification
Cold rolled steel shear rubber compression ring by combination with a metal ring can be divided into two categories (see Figure 1).
--- A class of monomer rubber and metal ring separate compression ring (YH-A);
--- Class B, with a metal ring is bonded to one of the rubber lined clamp ring (YH-B).
3.2 accuracy class
Cold rolled steel shear rubber compression ring according to their intended use is divided into four levels.
--- C1 level. for high-precision, high surface quality board (volume) material cut professional products, such as professional electrical steel, aluminum and other professional shear
Cutting equipment.
--- C2 level. for precision and surface quality requirements are relatively high shear products, mainly for automotive body panels, home appliances such as shear plate equipment.
--- C3 level. for processing of cold-rolled sheet, but the plate (volume) production quality requirements are generally low-end shearing equipment.
--- C4 levels. general quality requirements applicable to conventional sheet cutting products. Commonly used in slitting, shearing and other auxiliary equipment pressing
Roller (the clamping ring assembly), the separator shaft pinch effect can not afford a place.
