Single-cutting-edge disk slitting blade

Abstract

The invention relates to the tool manufacturing field, in particular to a single-cutting-edge disk slitting blade. The single-cutting-edge disk slitting blade comprises a disk-shaped blade body made from a tungsten steel alloy material; a round hole concentric with the blade body is arranged on the middle portion of the blade body; a square notch is formed in the edge position of the round hole; the two sides of the edge of the blade body are provided with knife edge parts; the diameter of the blade body is 130 mm; the diameter of the round hole is 88 mm; the thickness of the blade body ranges from 0.995 mm to 1.005 mm; an included angle a of the knife edge parts is 30 degrees; and the density of the tungsten steel alloy material used for manufacturing the blade body is 14.6 g / cm<3>, hardness is HRC74.5-75, the bending strength is 2900-3200 N / MM<2>, cobalt magnetization is 11.7%, and the particle diameter is 0.6-0.8 microns.

Description

technical field [0001] The invention relates to the field of tool manufacturing, in particular to a single-edge disc cutting blade. Background technique [0002] Slitting knives are very precise knives, designed to reduce downtime at all times on the job and high performance shearing, choose from the high performance range of pneumatic slitting knives or the new non-pneumatic slitters. The slitting knife is not only in terms of slitting materials, overspeed operation, but also the shape, sharpness and assembly parameters of the blade. The slitting knife is divided into an upper knife and a lower knife, which are installed on the knife shaft of the slitting machine, and use the rolling shear principle to slit various capacitor papers, aluminum foils, metallized films, and film films with a thickness of 0.01~0.1mm in rolls , Computer tapes and tapes, etc. [0003] Traditional slitting knives are often made of high-speed steel. High-speed steel has better process performance ...

AI Technical Summary

Problems solved by technology

[0003] Traditional slitting knives are often made of high-speed steel. High-speed steel has better process performance and low manufacturing cost, but daily anti-rust work must be done during the use of the knives, so it can only be used for general slitting work, and The service life is low, and tungsten steel is easier to process high-hard cutting tools due to its high hardness and hard and brittle physical characteristics. The cutting life is equal to dozens of times that of carbon steel, so compared with high-speed steel, it can To achieve a more ideal cutting effect
