Abstract

The invention discloses a three-edged cutting knife, which comprises a handle, on which a mounting column is integrally formed, and three groups of blades are detachably connected to the mounting column, and three sets of penetrating knives are arranged in the mounting column at equal intervals along the length direction of the mounting column. The chute in the handle is detachably connected with a slide rail that penetrates into the handle. The end of the slide rail away from the handle is connected with a connecting piece. The attached fastening plate has a blade integrally formed on the outside of the fastening plate; a fastening nut is installed on the top of the mounting column, and a locking nut is installed on the bottom of the mounting column between the blade and the knife handle. The invention facilitates the installation and replacement of damaged blades and can effectively reduce the use cost.

Description

technical field [0001] The invention relates to a three-edged cutting knife, which belongs to the technical field of wood processing. Background technique [0002] With the continuous development of wood processing technology, the CNC cutting machine has replaced the traditional cutting machine in the past two years and quickly occupied the market. Using the CNC cutting machine to directly process wood can realize cutting, trimming, simple profiling, etc. The process not only greatly saves the processing time and improves the efficiency, but also further improves the processing accuracy. [0003] At present, the cutting knives used by the cutting machine can be divided into keyway knives and end mills. The keyway knives are two-edged welded straight knives. Since the diameter of the two-edged straight knives is 8mm, it is not only too small and easy to break, but also the processing of wood is difficult. The waste of wood is more serious. End mills include three-edged cutt...
