Abstract
A kind of saw-blade type diamond scraper, comprises the some pieces of diamond segments be arranged on matrix, it is characterized in that the cutting edge of described diamond segment is provided with inclination angle; The span at described inclination angle is 15 ° ~ 75 °; The both sides of described diamond segment non-cutting sword are parallel to each other; Diamond segment entirety described in some pieces is arranged on matrix in shape of threads; Chip removal mouth is provided with between adjacent diamond cutter head.The utility model arranges inclination angle by the cutting edge at diamond segment, when making it cut, when work piece feeding, cushioning effect can be played, effectively prevent diamond segment and work piece from colliding, thus can product percent of pass be improved, and reduce wear, increase the service life, chip removal performance when simultaneously also can improve cutting and sharpness.In addition, this diamond segment, when manufacturing, can reduce manufacturing procedure, reduces sintering time, thus reduces production cost.
Description
Technical field
The utility model relates to a kind of diamond scraper, particularly a kind of saw-blade type diamond scraper.
Background technology
As shown in accompanying drawing 1, Fig. 3, diamond segment 2 cutting edge on existing saw-blade type diamond scraper is that the straight angle is arranged, this saw-blade type diamond scraper is when processing ceramic, stone material or glass, easy and work piece collides, thus cause waste product, and after this diamond edge-abrasive wheel uses a period of time, its sharpness declines very fast, cause working (machining) efficiency low, make user's not too satisfaction.Chinese patent literature CN204183730U discloses a kind of saw-blade type diamond hobboing cutter on March 4th, 2015, and specifically discloses it and comprise the blanking cover being arranged at diamond grinding block on steel pipe matrix and closed steel pipe matrix two ends; It is characterized in that: described diamond grinding block misses one another overlapping distribution.Described diamond grinding block each other head and the tail is overlapping, but non-fully is overlapping, relies on head and the tail overlying contact to be formed with continuous print diamond machined face.Described diamond grinding block presses the radial welding-on of spiral trajectory at steel pipe matrix surface.There is above problem in this structure, therefore, is necessary to make further improvements.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, cost of manufacture is low, long service life, quality stability are good, production efficiency is high, applied widely saw-blade type diamond scraper, to overcome weak point of the prior art.
By a kind of saw-blade type diamond scraper that this object designs, comprise the some pieces of diamond segments be arranged on matrix, it is characterized in that the cutting edge of described diamond segment is provided with inclination angle.
The span at described inclination angle is 15 ° ~ 75 °.
The both sides of described diamond segment non-cutting sword are parallel to each other.
Diamond segment entirety described in some pieces is arranged on matrix in shape of threads.
Chip removal mouth is provided with between adjacent diamond cutter head.
Described diamond segment and matrix by sinter, bond or assembly mode affixed mutually
Described diamond segment parallelogram is arranged.Or described diamond segment is also provided with the cutting edge at a reverse inclination angle of tool, and reverse inclination angle is different from inclination angle value, the span at reverse inclination angle is 15 ° ~ 75 °.
The utility model arranges inclination angle by the cutting edge at diamond segment, when making it cut, when work piece feeding, cushioning effect can be played, effectively prevent diamond segment and work piece from colliding, thus can product percent of pass be improved, and reduce wear, increase the service life, chip removal performance when simultaneously also can improve cutting and sharpness.In addition, this diamond segment, when manufacturing, can reduce manufacturing procedure, reduces sintering time, thus reduces production cost.It has simple and reasonable, that production efficiency is high, long service life, quality stability are good, applied widely feature.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
First embodiment
See Fig. 2, this saw-blade type diamond scraper, comprise the some pieces of diamond segments 3 be arranged on matrix 1, the cutting edge of diamond segment 3 is provided with inclination angle, and the value at inclination angle is 75 °.The both sides of diamond segment 3 non-cutting sword are parallel to each other, and diamond segment 3 left and right sides namely in Fig. 4 is parallel to each other, these two sides again respectively with the rotational axis vertical of diamond scraper.
In this structure, some pieces of diamond segment 3 entirety are arranged on matrix in shape of threads.Non-overlapping copies between adjacent diamond cutter head 3, and leave gap, form the chip removal mouth b being used for chip removal.
Conveniently manufacture, diamond segment 3 parallelogram is arranged, and makes that a diamond segment 3 has two identical cutting edges, and the inclination alpha that tool is identical, can consider during installation that the installation of both forward and reverse directions coordinates; In addition, the forward or reverse of saw-blade type diamond scraper all can reach the technique effect of needs, after wherein a cutting edge lost efficacy, can reverse and use another cutting edge.
Diamond segment 3 and matrix 1 by sinter, bond or assembly mode affixed mutually.
Second embodiment
This saw-blade type diamond scraper is different from the first embodiment part and is: the inclination alpha value on described diamond segment 3 is 60 °, 45 °, 30 ° or 15 °.
Other do not state part with the first embodiment, no longer describe in detail here.
3rd embodiment
See Fig. 5-Fig. 6, this saw-blade type diamond scraper is different from the first embodiment part and is: described diamond segment 3 is non-parallel quadrangle setting, the both sides of its non-cutting sword are parallel to each other, upper and lower side is two differences and cutting edge reverse each other, a α with angle, another band negative side inclination alpha ', reverse inclination alpha ' different from the value of inclination alpha.
The value of inclination alpha is 75 °, reverse inclination alpha ' value be 15 °;
Or the value of inclination alpha is 60 °, reverse inclination alpha ' value be 30 °;
Or the value of inclination alpha is 30 °, reverse inclination alpha ' value be 60 °;
Or the value of inclination alpha is 15 °, reverse inclination alpha ' value be 75 °.
Install diamond segment 3 time, the cutting edge of the identical inclination alpha of tool all towards same direction, the identical reverse inclination alpha of tool ' cutting edge arrange all in the opposite direction.
This structure is owing to having possessed the cutting edge of two different angles, and therefore have two kinds of different processing effects, user can select applicable cutting edge for different workpiece; For the switching of different cutting edge, only need change and turn to and can realize, other diamond scraper need not be changed, simple to operation.
Other do not state part with the first embodiment, no longer describe in detail here.
Above-mentioned is preferred version of the present utility model, and those of ordinary skill in the art, to its simple modification or transformation, all drop within protection domain of the present utility model.
