Slitting circular cutter

Abstract

A slitting circular cutter comprises a cutter body. A center hole is formed in the center of the cutter body. A plurality of transmission holes are formed near the outer circle of the center hole, anda plurality of cutter bits are arranged on the outer circle of the cutter body. Each cutter bit is composed of a plurality of segmented blocks circumferentially and evenly distributed around the outer edge of the cutter body. The segmented blocks are made of hard alloys or metal ceramics. Different from a traditional cutter body and cutting edge integrated slitting circular cutter, the cutter body of the slitting circular cutter is made of ordinary high-quality carbon steel, the hard alloys or the metal ceramic segmented blocks are welded to the cutter body for truing and dressing, and the cutter body is made of ordinary materials so that the manufacturing cost and the heat treatment difficulty can be reduced. The cutting edge is composed of super abrasion resisting hard alloys or the metal ceramic segmented blocks so that the service life of the cutting edge can be long; and in addition, the cutting feeding cutter angle of the hard alloys or the metal ceramic segmented blocks of thecutting edge is the obtuse angle, tearing and cutting of fracture face materials can be prevented, and the cutting quality of the slitting circular cutter is improved.

Description

technical field [0001] The invention belongs to the field of cutter cutting, and in particular relates to a slitting circular knife used for cutting paper, steel strips, aluminum foil, non-woven fabrics, rock wool and plastic films. Background technique [0002] The application of the slitting circular knife began with the rise of the papermaking machinery industry, and now it is not only used in the papermaking industry machinery, but also widely used in the derivatives of paper products, steel strips, aluminum foil, non-woven fabrics, rock wool and plastics Film and other cutting fields. The production technology of domestic slitting round knives is limited by the level of steelmaking technology and the production technology started late, and it is still far behind some developed countries in the West. expensive. The body and head of the slitting round knife made of conventional materials are integrated, the blade is easy to wear and not durable after long-term use, an...

Problems solved by technology

The production technology of domestic slitting round knives is limited by the level of steelmaking technology and the production technology started late, and it is still far behind some developed countries in the West. expensive

The body and head of the slitting round knife made of conventional materials are integrated, the blade is easy to wear and not durable after long-term use, and the overall heat treatment of the material is difficult. Slitter round knives are durable but expensive to make
