Rolling shear blades, also known as disc blades, slitter blades, and slitter blades, are a kind of slitting tool used in slitting equipment in the metal sheet industry. .
Components: blade, separator, spacer.
Spacer: The material of the blade casing is S45C, S50C, 65MN, etc., among which S45c is a commonly used material. The purpose of using the blade sleeve is to keep the gap between the slitting circular knives, and to adjust the upper and lower blades and the horizontal gap; the thickness of the commonly used blade sleeve is between 0.9MM~200MM, and the hardness is 47±2 degrees , the thickness tolerance of the blade casing is also controlled within 0.002M/MT.
Separator: The commonly used materials for separators are SKD—61 [4CR5MOSIV1], 40CRMO.CR12, etc., among which SKD—61 is the commonly used material; SKD—61 has a good balance between high temperature strength and toughness, and is mainly used for thin plate slitting to complete the collection work , so that the steel strips can maintain the gap without colliding with each other. During the manufacturing process of the separator, we undergo heat treatment, leveling, fine grinding, polishing, chrome plating (0.05M/MT), and then polishing to make the surface smooth and flat, and the separated steel bars are neat and smooth.
Material: 9CRSk 5CRW2SI, 6CRW2SL CR12M0V, LD, D2, HSS, W6M05CR4V2, W18CR4V, H13, H13K, HS-51, medium carbon steel, high carbon steel, high speed steel, front steel, busbar steel, stainless steel, etc.
Features: The product has no breakage, burr, burr, gap, soft mouth and other phenomena in the slitting, and the knife edge is smooth and flat, and the cutting edge is sharp. Our company can produce circular scissor blades with a diameter of less than 1.2 meters and circular shear blades with a diameter of less than 0.5 meters, and the parallelism can reach 0.002MM.
Scope of application:
1. Trimming: A variety of materials are combined to form process trims. By cutting off the process trims reserved in the process, products that meet the process requirements are obtained. This cutting method is mostly used in the processing of materials such as composite films.
2. Roll cutting: the whole roll of wide and coiled material is cut into multiple rolls of narrow-sized coiled material by a high-speed circular knife. This cutting method is mostly used in the adhesive product industry;
3. Rolling: Cut the large roll diameter material into multiple rolls and small roll diameter materials according to the requirements of the winding length and width specifications. This cutting method is mostly used for film substrates and flexible packaging
Color printing industry.
Cutting objects: OPP sealing tape, Mara tape, kraft paper, double-sided tape, masking paper, protective film, electrical adhesive, paper, film, gold foil, silver foil, copper foil, aluminum foil, tape
Application: An important component of the metal slitting unit, suitable for large iron and steel manufacturing plants, non-ferrous metals, processing plants, binding material plants, cold rolling plants, packaging material plants, steel screen plants, strip steel plants, distribution plants, etc.
Machine manufacturers, etc.
