Problems solved by technology

[0002] At present, two processing methods are generally used for paper shredder blades. One is overall processing and forming, that is, the blade and the cutter shaft are integrated; the other is split forming, that is, the blade and the cutter shaft are processed separately, and then assembled with the cutter shaft. One-piece, this kind of split blade is formed by one-time stamping. After punching, it is used directly without processing. The method is simple and the price is low. However, due to the rough surface of the processed blade, the friction resistance is relatively large, reducing the amount of shredded paper. Shredded paper is not ideal

Abstract

The present invention relates to a method for making blade of cone breaker. Said invention method includes the following steps: blanking-forming and grinding blade. The roughness of two side surfacesof blade can be reduced, deformation of blade also is reduced, and the surface finish quality of raised, and the frictino between assembled blades is greatly reduced, and the noise also is reduced, so that it can prolong service life of blade, and can raise its paper-breaking quantity and paper-breaking effect.

Description

technical field [0001] The invention relates to a method of manufacturing shredder blades. Background technique [0002] At present, two processing methods are generally used for paper shredder blades. One is overall processing and forming, that is, the blade and the cutter shaft are integrated; the other is split forming, that is, the blade and the cutter shaft are processed separately, and then assembled with the cutter shaft. One-piece, this kind of split blade is formed by one-time stamping. After punching, it is used directly without processing. The method is simple and the price is low. However, due to the rough surface of the processed blade, the friction resistance is relatively large, reducing the amount of shredded paper. The shredding effect is also not ideal. Contents of the invention [0003] The purpose of the present invention is to avoid the deficiencies in the prior art, and provide a shredder blade manufacturing method with small deformation, long servic...
