Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail in conjunction with the above drawings.

[0016] Depend on Figure 1 to Figure 4 As can be seen in the figure, this cutting tool includes a disc-type cutter body 10 with a central hole 11, and is fixed to a plurality of independent blades 20 on the edge of the cutter body, and each blade 20 is arranged along the helical direction of the cutter body 10, the The helix spreads out from the center hole 11 of the disc cutter body 10 to the outer edge. In the present invention, the blade 20 is arranged along the helical direction of the blade body 10, and forms a strong support for the blade during the cutting operation, so as to ensure that the blade will not collapse due to excessive force during cutting.

[0017] Depend on figure 1 with figure 2 It can be seen from the figure that the blade width of each blade 20 is greater than the thickness of the blade body 10 , and both sides protrude from th...

Abstract

The invention relates to a cutting tool which comprises a wafer type cutter body (10) with a central hole (11) and a plurality of cutting edges (20) fixed on the periphery of the cutter body, wherein the cutting edges (20) are arranged along the direction of a spiral line of the cutter body (10), and the spiral line is expanded towards the periphery from the central hole (11) of the cutter body (10); the cutting edges (20) are in a curve shape from an edge (21) to a cutting edge bottom (22). A wafer type plane cutter (14) is clamped between two cutting tool blades (13), and the two cutting tool blades (13) and the wafer type plane cutter (14) are fixed into a whole by welding or rivets. The novel cutting tool has the characteristics of self induced air cooling, large supporting force of acutting edge body to the cutting edges and no waste scrap flying after cutting, has the advantages of convenient and quick slotting, much more applicability to double-motor cutting tools, and the like and has good economy and practicability.

Description

technical field [0001] The present invention relates to processing equipment and in particular to cutting or grooving knives for cutting earth and rock material. Background technique [0002] The cutting and grooving cutters in the prior art are generally in the form of straight blades. This straight blade cutter not only has poor ventilation and cooling, but also causes dust to fly around and pollute the surrounding environment. In addition, this straight-edged tool is also prone to chipping due to insufficient support of the blade body to the cutting edge, which affects the service life of the tool. Contents of the invention [0003] The invention provides a cutting tool, which adopts the method that the blade body is arranged along the direction of the outer helix of the cutter blade to strengthen the support of the blade body to the cutting edge, and at the same time, a channel for guiding wind and chips is formed between two adjacent blades, so as to solve the problem...
