Improved wood product machining straight knife

Abstract

The invention discloses an improved wood product machining straight knife. The knife comprises a knife head portion and a knife handle portion connected with the rear end of the knife head portion; the maximum outer diameter of the rear end of the knife head portion is the same with the outer diameter of the knife handle portion, at least one annular groove is formed in the side, close to the knife head portion, of the knife handle portion, an opening elastic clamping ring is arranged in each annular groove, and the outer diameter of each opening elastic clamping ring is larger than the outer diameter of the knife handle portion. The improved wood product machining straight knife has the beneficial effects of being low in machining cost, high in production efficiency and flexible to use.

Description

technical field [0001] The present invention relates to a kind of knife, more specifically, relates to an improved straight knife for processing wood products. Background technique [0002] In today's wood product processing and production, straight knives are one of the widely used knife products. The existing straight knife structure such as figure 1 As shown, it is made up of a cutter head 10 and a handle of a knife 20 connected with the rear end of the cutter head 10. The outer diameter of the rear end of the cutter head 10 is greater than the outer diameter of the handle of a knife 20. During use, the handle of a knife 20 is placed Into the collet, because the outer diameter of the cutter head 10 rear end is greater than the outer diameter of the handle portion 20, the cutter head 10 rear end contacts the chuck end to support the effect of fixing the cutter body. Because the outer diameter of the cutter head 10 rear end of the existing straight knife is greater than t...

AI Technical Summary

Problems solved by technology

Because the outer diameter of the cutter head 10 rear end of the existing straight knife is greater than the outer diameter of the handle portion 20, it is necessary to use a workpiece blank with the outer diameter of the cutter head 20 as the outer diameter during processing, and then according to the shape of the straight knife Milling out the head and shank of the cutter body separately has the disadvantages of many processing steps, long processing time, and large material loss, which also increases the production cost

Moreover, the depth of inserting the shank of the straight knife into the chuck is relatively fixed, and the insertion depth of the shank cannot be adjusted. The use of the tool is not flexible enough to meet the processing requirements.
