Combinations thereof formula bar breaking tool is characterized in that, it is one skewed that the lateral surface of this fixed disk is.

Combinations thereof formula bar breaking tool is characterized in that, this cutting ring is a stamping parts.

One fixed disk, one end are extended with a flange;

One ringwall, the periphery of this flange extends certainly; And

One cutting ring has a through hole that supplies this flange cross-under and a blade that takes shape in its outer peripheral edges, and this cutting ring and this fixed disk are unlike material spare;

Wherein, this ringwall type that is bent into is also pulled this cutting ring folder and is packed on this fixed disk.

Combinations thereof formula bar breaking tool is characterized in that, this ringwall is pulled this cutting ring folder for the rolling mode bends and is packed on this fixed disk.

Combinations thereof formula bar breaking tool is characterized in that, this fixed disk forms a location salient point, and this cutting ring forms a locating slot that fixes mutually with this positioning convex point.

Combinations thereof formula bar breaking tool is characterized in that, it is one skewed that the lateral surface of this fixed disk and this ringwall all is.

The utility model is compared to the effect that prior art reached, and solves existing itemize cutter and is formed in one, the shortcoming of more material cost of cost and processing cost on making; The fixed disk and the cutting ring of the utility model combined type bar breaking tool are made of unlike material, can select comparatively cheap but the material that intensity is enough of price when making fixed disk for use; The utility model is then comparatively simple and easy on technology, and can save material cost, processing cost and time cost; In addition, the utility model also can solve existing integrated itemize cutter under long-time the use, and radiating efficiency does not apply the shortcoming of using; The utility model can be selected the enough and thermal conductivity good metal material of intensity for use in the cutting ring part, to improve radiating efficiency.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

The specific embodiment

Relevant detailed description of the present utility model and technology contents cooperate graphic being described as follows, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the utility model is limited.

See also Fig. 1 and Fig. 2, be respectively the sectional view () of the utility model manufacturing process and the sectional view (two) of the utility model manufacturing process, the utility model provides a kind of combined type bar breaking tool, comprises a fixed disk 10, a ringwall 20 and a cutting ring 30, wherein:

One end face of fixed disk 10 is extended with a flange 11; And fixed disk 10 offers a through hole 12 and wears fixing for board (figure do not show).Fixed disk 10 can be selected the enough but cheap material of intensity for use, as plastic-steel, but not as limit.

Ringwall 20 extends from the periphery of flange 11; And ringwall 20 is vertical mutually with fixed disk 10, and the inner edge surface of ringwall 20 is skewed.

Cutting ring 30 has a through hole 31 that supplies flange 11 cross-under and a blade 32 that takes shape in its outer peripheral edges, and cutting ring 30 is a unlike material with fixed disk 10.The material of cutting ring 30 can be SKD-11 mould steel, but not as qualification.Further specify, because thinner thickness and its thickness homogeneous of cutting ring 30, so can utilize Sheet Metal Forming Technology to make cutting ring 30 so that cutting ring 30 is a stamping parts.After utilizing Sheet Metal Forming Technology that cutting ring 30 is made, its blade 32 of reshaping and the surface of cutting ring 30 ground so replaces and makes cutting ring 30 with milling process, can save time cost, material cost and processing cost.

Wherein, ringwall 20 is bent into type and cutting ring 30 folder is pulled and is packed on the fixed disk 10.Further specify, when this combined type bar breaking tool 1 of processing, cutting ring 30 is sheathed on the flange 11 of fixed disk 10.Utilize roller mill with ringwall 20 bending downwards 90 degree afterwards again, be packed on the fixed disk 10 so that cutting ring 30 folders are pulled.And fixed disk 10 and be bent into type after the lateral surface of ringwall 20 be all skewedly, can concentrate the strength of fixed disk 10 clamping cutting rings 30.

And ringwall 20 is before the type of being bent into, and it is the skewed end face center of circle towards fixed disk 10; So when using the roller mill moulding, can be during ringwall 20 pressurizeds naturally towards fixed disk 10 outside bending formings.

See also Fig. 3 and Fig. 4, be respectively three-dimensional exploded view of the present utility model and stereo appearance figure of the present utility model, please, when making this modular cutting tool assembly 1, can utilize technologies such as rolling, casting or ejection formation that fixed disk 10 is combined with cutting ring 30 in the lump with reference to figure 1 and Fig. 2.Further specify, fixed disk 10 is can the die cast mode made, thus the combined type bar breaking tool that the utility model provides in the die cast mode when made, 1 on cutter comprises a cutting ring 30 and a fixed disk 10, wherein:

The blade 32 that cutting ring 30 has a through hole 31 and takes shape in its outer peripheral edges.Fixed disk 10 is coated on the through hole 31 periphery upper and lower end faces of cutting ring 30 with die casting mode part, and with the packing of pulling of cutting ring 30 folders.

See also Fig. 5, be the sectional view of another embodiment of the utility model, in the present embodiment, fixed disk 10 forms a plurality of positioning convex points 13, and cutting ring 30 forms a plurality of locating slots 33 that fix mutually with positioning convex point 13 respectively.This modular cutting tool assembly 1 because facility are held on the fixed disk 10, comes with fixed disk 10 fixingly so cutting ring 30 can be engaged by positioning convex point 13 and locating slot 33 mutual when the high speed rotary cutting, makes cutting ring 30 can not produce relative slip with fixed disk 10.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
