Wrinkling cutter and manufacturing method thereof

The invention provides a wrinkling cutter and a manufacturing method thereof. The wrinkling cutter comprises a base. The top end face and the work face of the base are provided with wear-resistant coatings. The manufacturing method of the wrinkling cutter comprises the following steps that the wear-resistant coatings are formed on the top end face and the work face of the base, and the wrinkling cutter is obtained through grinding. The contact portion of the wrinkling cutter and a drying cylinder is very small and constant, the shape is stable, and the wrinkling cutter is of a strip-shaped structure with the width being just 0.15-0.40 mm, so that the paper surface wrinkle structure on paper basically has no change. By the adoption of the technical scheme, the linear pressure of a cutting edge of the wrinkling cutter is generally 2.5-3 N/mm, so that friction force between the wrinkling cutter and the drying cylinder is effectively reduced, resistance in the rotation process of the drying cylinder is reduced, and the purpose of saving energy is achieved. The wrinkling cutter integrates the advantages that the friction portion is constant in area and is provided with the high-wear-resistance coatings, the paper surface impacted portion has the high wear resistance and high impact resistance, and the service life is 30-60 times that of a common steel wrinkling cutter.
