Abstract
The utility model provides a multilayer combined type diamond segments, it relates to cutter technical field, and it contains tool bit body, soft matrix, powder diamond, the tool bit body constitute by soft matrix and powder diamond, crisscross the setting to the multilayer of soft matrix and powder diamond, and tool bit body outmost is soft matrix. A multilayer combined type diamond segments, can reduce the use amount of valuable powder, reduction in production cost, the tool bit is sharp, cut efficient, the utility model has the advantages of simple structure, set up reasonable, the cost of manufacture low.
Description
Technical field
The utility model relates to cutting-tool engineering field, is specifically related to a kind of multi-layer combined diamond segment.
Background technology
Diamond is a kind of superhard material, plays the effect of cutting edge, is made up of metal simple-substance powder or metal alloy powders, and different compositions is called formula, according to different purposes, fills a prescription different with diamond.
When diamond grit thick and be Monosized powder time, saw blade tip is sharp, and cutting-rate is high, but the decline of the bending strength of diamond segment; When diamond grit is thin or thickness granularity mixes, saw blade tip durability is high, but efficiency is lower.Consider above factor, select diamond grit to be that 50/60 order is comparatively suitable.
Within the specific limits, when diamond concentration changes from low to high, sharpness and the cutting-rate of saw blade decline gradually, and service life then extends gradually; But excessive concentration, saw blade can rust.And adopting low concentration, coarseness, efficiency then can improve.Utilize the not same-action of each position of cutter head when sawing, adopt variable concentrations (namely intermediate layer can adopt low concentration in three layers or more Rotating fields), in saw cutter process, cutter head work forms intermediate groove, be conducive to preventing saw blade beat, thus improve processing of stone quality.
Adamantine intensity is the important indicator ensureing cutting performance.Too high intensity can make crystal not easily broken, and abrasive particle is polished in use, and sharpness declines, and causes tool performance to worsen; When diamond intensity is inadequate, easily broken after being impacted, be difficult to undertake cutting important task.Therefore answer selection intensity at 130 ~ 140N.
The diamond segment of prior art adopts metal simple-substance powder or metal alloy powders, and its production cost is high, and be worn after using a period of time, cutting efficiency is low.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides the multi-layer combined diamond segment that a kind of structure is simple, reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises bit body, soft carcass, powder diamond; Described bit body is made up of soft carcass and powder diamond; Described soft carcass and powder diamond are crisscross arranged as multilayer, and the outermost layer of bit body is soft carcass.
Principle of the present utility model is: at diamond tool layering filling and larger than former cutter head powder diamond grit, that concentration the is low soft carcass in front of original high-frequency welding; In use procedure, soft carcass weares and teares in advance, makes bit body indentation, reduces the contact area between bit body and powder diamond, increases cutting sharpness.
After adopting said structure, the beneficial effect that the utility model produces is: the multi-layer combined diamond segment of one described in the utility model, the use amount of valuable powder can be reduced, reduce production cost, cutter head is sharp, cutting efficiency is high, the utility model have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1, bit body; 2, soft carcass; 3, powder diamond.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, this detailed description of the invention adopts following technical scheme: it comprises bit body 1, soft carcass 2, powder diamond 3; Described bit body 1 is made up of soft carcass 2 and powder diamond 3; Described soft carcass 2 and powder diamond 3 are crisscross arranged as multilayer, and the outermost layer of bit body 1 is soft carcass 2.
The principle of this detailed description of the invention is: at diamond tool layering filling and larger than former cutter head powder diamond grit, that concentration the is low soft carcass 2 in front of original high-frequency welding; In use procedure, soft carcass weares and teares in advance, makes bit body 1 indentation, reduces the contact area between bit body 1 and powder diamond 3, increases cutting sharpness.
After adopting said structure, the beneficial effect that this detailed description of the invention produces is the one described in this detailed description of the invention multi-layer combined diamond segment, the use amount of valuable powder can be reduced, reduce production cost, cutter head is sharp, cutting efficiency is high, this detailed description of the invention have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
