Embodiment Construction

[0019] Such as Figure 3 to Figure 5 As shown, the thermal spraying manufacturing method of a corrugated roll according to the present invention includes the following method steps: firstly, the corrugated roll is subjected to tooth profile processing; then, the tooth portion of the corrugated roll is subjected to nitriding treatment or carbon-nitrogen chemical treatment; secondly, local heat quenching and tempering are carried out on the teeth of the corrugating roller; and then the tooth surface of the corrugating roller is strengthened with a wear-resistant coating;

[0020] Among them, the supersonic spraying system is used to strengthen the wear-resistant coating on the tooth surface of the corrugated roller. The steps of the method for quickly determining the spraying angle of the spray gun are as follows:

[0021] (1) According to the tooth shape parameters of the corrugating roller, the cross-sectional tooth shape of the corrugating roller is drawn proportionally by co...

Abstract

The thermal spraying manufacture and repair method for corrugated roller comprises: processing the gear form of roller; taking nitridation or carbonization- nitridation treatment to the gear; localized heat quenching and tempering to roller gear; taking abrasion resistant coating strengthen treatment to tooth surface. By drawing roller section gear form figure and plotting horizontal line and tangent line to calculate the spraying point and abrasion resistant coating, this invention can ensure coating evenness, obtains clean and rigid work surface, improves roller properties, and increases roller economical benefit.

Description

technical field [0001] The invention relates to a method for manufacturing corrugated rollers by thermal spraying. Background technique [0002] The corrugating roller is a key component in the manufacture of corrugated paper. Its principle is to use a pair of toothed rollers to mesh with each other to produce corrugated paper. At present, in order to prolong the service life, save pulp, and reduce costs, medium and high-speed corrugated rollers usually use supersonic spraying system to spray cemented carbide (tungsten carbide) on the surface of corrugated rollers to strengthen them. After spraying, polishing is generally adopted to meet the use requirements. of smoothness. Therefore, the tooth surface coating is required to be evenly distributed, that is, the coating is evenly distributed on the top, side and bottom of each tooth. Currently generally used as figure 1 , figure 2 The method shown: the workpiece B1 rotates, and the spray gun B2 moves up and down parallel ...
