Abstract

The utility model relates to a woodwork cutter, comprising a cutter body and a blade which is inlayed on the cutter body. The woodwork cutter is characterized in that the blade with a trapezoidal cross section is changed into a blade with a quadrangular cross section and smaller size. The new technical scheme saves more than half of the noble metal of tungsten steel; and the blade with smaller size can be more firmly inlayed on the cutter body and be difficult to drop, without affecting the cutting effect.

Description

A kind of wood cutter

Technical field

The utility model relates to a kind of wood cutter, especially processes the cutter that the bamboo bar is used.

Background technology

Existing bamboo bar process tool generally is made up of cutter hub and blade two parts, and blade is embedded on the cutter hub, and the cutting function is finished by blade.The cross sectional shape of blade is generally trapezoidal, and service wear and sharpening loss partly are knife edge part, and the material of making blade is generally precious metal wolfram steel, and wolfram steel price height has embodied the value of whole cutter substantially.In addition, the blade of inlaying in the high speed operation comes off owing to stressed also being easy to.

The utility model content

At the above-mentioned problems in the prior art, the purpose of this utility model is to design and provides that a kind of cost is low, the bamboo bar process tool of blade difficult drop-off.

For achieving the above object, the technical solution adopted in the utility model is to be that to change the littler cross sectional shape of volume into be the blade of parallelogram to trapezoidal blade with original cross sectional shape.

Described blade cross sectional shape also can adopt rhombus or irregular pentagon.

New technical scheme has been saved precious metal wolfram steel consumption over half, because the blade volume is littler, be embedded in difficult drop-off on the cutter hub more firmly, and cutting effect is without any influence.

Description of drawings

Fig. 1 is the cross section structure schematic diagram of prior art wood cutter;

Fig. 2 is irregular pentagonal structural representation for cross sectional shape of the present utility model;

Fig. 3 is the structural representation of rhombus for cross sectional shape of the present utility model;

Fig. 4 is a cross section structure schematic diagram of the present utility model;

Among the figure: 1-blade, 2-cutter hub.

The specific embodiment

For making the auditor can further understand the utility model is to reach the technical scheme that predetermined purpose is adopted, now for an embodiment that 12 cutter heads are arranged.

The utility model is described in further detail below in conjunction with Figure of description:

Shown in Fig. 1 to 4, be wood cutter of the present utility model, form by cutter hub 2 and blade 1.The cross sectional shape of the blade 1 of prior art is trapezoidal among Fig. 1, and volume is bigger, now changes blade 1 into wolfram steel that cross sectional shape is a parallelogram, and as shown in Figure 4, the volume ratio prior art of blade 1 reduces over half.Because blade 1 volume reduces, its adhesive force of inlaying is bigger, thus difficult drop-off, and more save system cutter cost.Fig. 2, blade 1 cross sectional shape that is respectively shown in Figure 3 are the wood cutter of irregular pentagon and rhombus, and its effect and wood cutter shown in Figure 4 are suitable.

Claims (3)

1. a wood cutter comprises cutter hub (2), is embedded in the blade (1) on the cutter hub (2), and it is characterized in that: the cross sectional shape of described blade (1) is a parallelogram.

2. wood cutter according to claim 1 is characterized in that: the cross sectional shape of described blade (1) is a rhombus.

3. wood cutter according to claim 1 is characterized in that: the cross sectional shape of described blade (1) is irregular pentagon.
