Description

The assemble or disassemble bar breaking tool

Technical field

The utility model relates to a kind of bar breaking tool, relates in particular to a kind of assemble or disassemble bar breaking tool.

Background technology

Cutting knife in the existing pneumatic set of knives of itemize is generally one-body molded, and promptly whole cutter body is by being gone down to be processed into a kind of material.The structure of cutting knife is generally a disk body, the cutting region that this disk body is divided into a clamp area and is formed at the clamp area outside; Usually the thickness of clamp area is greater than cutting region, so that facility can firmly press from both sides the cutting knife of pulling.

When making cutting knife, must utilize the monoblock steel to carry out milling, unnecessary steel are removed, grind in the clamp area surface again to guarantee the flatness of clamp area at last; But the volume of the steel that removed in milling process then may be equal to the volume of cutting knife itself, considerably waste material cost.

And the blade that is formed at the cutting region outer rim also must treat that milling processes after finishing again; So numerous and diverse procedure of processing just improves and makes material cost and the processing cost that this cutting knife spent; Moreover the integrated cutting knife of this kind then also has radiating efficiency and does not apply the problem of using under long-time the use; In addition, because cutting knife is formed in one, after long-time the use, the blade of cutting knife is with heavy wear, and then must change whole cutting knife this moment, so then than waste material.

The utility model content

A purpose of the present utility model is to provide a kind of assemble or disassemble bar breaking tool, is not formed in one and to can be unlike material made by cutting ring and first and second fixed disk, simplifies the cutter processing technology, to save material cost and processing cost.

To achieve the above object, the utility model provides a kind of assemble or disassemble bar breaking tool, comprise one first fixed disk, one cutting ring, one second fixed disk and a plurality of fixation kit, wherein, one end face of this first fixed disk is extended with a flange, this cutting ring has a through hole that supplies this flange cross-under and a blade that takes shape in its outer peripheral edges, this cutting ring and this first fixed disk are unlike material spare, this second fixed disk amplexiforms on this cutting ring, those fixation kits respectively cross-under this first, two fixed disks, and make this cutting ring by this first, two fixed disks institute packing folder is pulled.

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; First and second fixed disk and the cutting ring of the utility model assemble or disassemble bar breaking tool are made of unlike material, can select comparatively cheap but the material that intensity is enough of price when making holder for use; Again, the utility model is then comparatively simple and easy on technology, can save material cost and processing 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, and can select the enough and thermal conductivity good metal material of intensity for use in the cutting ring part, to improve radiating efficiency; Moreover the itemize cutter will make knife edge part heavy wear under long-time the use, only changes cutting ring this moment and can continue to use material cost and the use cost that can save the itemize cutter.

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 to Fig. 3, be respectively three-dimensional exploded view of the present utility model, stereo appearance figure of the present utility model and Fig. 2 cutaway view along the 3-3 hatching, the utility model provides a kind of assemble or disassemble bar breaking tool 1, comprises a pedestal 10, a cutting ring 20 and a plurality of fixation kit 30, wherein:

Pedestal 10, an end face that comprises one first fixed disk 11 and one second fixed disk, 12, the first fixed disks 11 is extended with a flange 112, the second fixed disks 12 and amplexiforms on cutting ring 20; First fixed disk, 11 axis parts offer one first through hole 111, and second fixed disk 12 also offers one second through hole 121 of corresponding first through hole 111.First fixed disk 11 also offers a plurality of first perforations 113, and is same, and second fixed disk 12 also offers a plurality of second perforations 122 of respectively corresponding these a little first perforations 113.

In addition, first fixed disk 11 and second fixed disk 12 can use the comparatively cheap material of price to save material cost, and for example plastic-steel, or other material is not limited.

Cutting ring 20 has a through hole 23 that supplies flange 112 cross-under and a blade 21 that takes shape in its outer peripheral edges, and the cutting ring 20 and first fixed disk 11 and second fixed disk 12 are unlike material; The material of cutting ring 20 can be SKD-11 mould steel, but not as qualification.

Further specify, because thinner thickness and its thickness homogeneous of cutting ring 20, so can utilize Sheet Metal Forming Technology to make cutting ring 20 so that cutting ring 20 is made with impact style.After utilizing Sheet Metal Forming Technology that cutting ring 20 is made, its blade 21 of reshaping and the surface of cutting ring 20 ground so replaces and makes cutting ring 20 with milling process, can save time cost, material cost and processing cost.

And the lateral surface of first fixed disk 11 and second fixed disk 12 all is one skewed, its role is to concentrate strength on, and improves the strength of first fixed disk 11 and second fixed disk, 12 clamping cutting rings 20.

Fixation kit 30 is cross-under first fixed disk 11 and second fixed disk 12 respectively, and cutting ring 20 is pulled by first fixed

disk

11 and 12 packing folders of second fixed disk.

Further specify, in the present embodiment, fixation kit 30 is a screw, and fixation kit 30 wears and is bolted in first perforation 113 and second perforation 122; When changing cutting ring 20, fixation kit 30 is unloaded, to replace new cutting ring 20 and again fixation kit 30 lockings are got final product, the cutting ring 20 of changeable type can significantly be saved the cost that uses cutter.

See also Fig. 4, be the sectional view of another embodiment of the utility model, in the present embodiment, fixation kit 30 can be a rivet, but does not exceed with this kenel.

See also Fig. 5, sectional view for the another embodiment of the utility model, in the present embodiment, first fixed disk 11 forms a location projection 114, second fixed disk 12 forms a location projection 123, and cutting ring 20 forms a plurality of locating slots 22 for positioning convex column 114 and positioning convex column 123 fixings.But do not limit on first fixed disk 11 and second fixed disk 12 and all must form positioning convex column 114,123, select one and get final product.

This assemble or disassemble cutter 1 because facility are held on the pedestal 10, comes with pedestal 10 fixingly so cutting ring 20 can be engaged by positioning convex column 114,123 and locating slot 22 mutual when the high speed rotary cutting, makes cutting ring 20 can not produce relative slip with pedestal 10.
