Description
Technical field
The present invention relates to a kind ofly be used to cut or the drilling brittle workpiece segment of cutting of the cutting element of stone, fragment of brick, concrete and pitch for example, and the cutting element with segment of cutting.More specifically, the present invention relates to a kind of can be by the segment of cutting that abrasive grain improves the stock-removing efficiency of abrasive grain suitably be set, and cutting element with this segment of cutting.
Background technology
In order to cut or drilling brittle workpiece for example stone, fragment of brick, concrete and pitch, must provide hardness to be higher than the abrasive material of workpiece hardness.
Abrasive material comprises diamond particle, natural diamond particle, boron nitride particle and superhard matter particle, and artificial diamond's stone granulate is most widely used general in these materials.
Diamond (being called as " diamond " below) is in the twentieth century invention fifties.It is the hardest material in all material on earth that diamond is known as, because this characteristic, so diamond has been used for cutting element and grinding tool.
Especially, diamond has been widely used in cutting and the various stones of grinding for example in the building field of granite and marmorean stone manufacture field and cutting and grinding xoncrete structure.
To describe based on segment of cutting and the cutting element of employing now as the diamond particles of abrasive material.
Typically, diamond tool comprise have diamond particles distribute thereon section (Segments) and have metal-cored that this section is fixed thereon.
Fig. 1 illustrates an example of segmentation diamond tool.
As shown in Figure 1, this segmentation diamond tool comprises a plurality of sections 11,12 that are fixed to metallic disc-shaped core 2, the diamond particles 5 that has random distribution on each section 11,12.
Described section utilization mixes the back with metal dust and adopts bonding, powder metallurgical technique molded and sintering then to make.
When diamond particles was mixed with metal dust, diamond particles was not evenly distributed in the metal dust but is randomly dispersed in described section.
For the cutting element that has described section thereon, cutting speed and the relation between service life are conflicting.That is,, a little less than active force between the diamond particles, then shorten service life if adopt low wear-resistant metal dust to improve cutting speed.On the contrary, if adopt high wear-resistant metal dust to increase service life, the diamond particles difficult drop-off owing to rust in working angles then makes and has reduced cutting speed in some cases.
Equally, when diamond particles being mixed with metal dust and is bonded together, because the difference of granular size and weight then produces diamond particles uneven distribution in metal dust.As a result, as shown in Figure 1, according to cutting surface, diamond particles can be with different CONCENTRATION DISTRIBUTION: cutting surface 3 can be distributed with very many diamond particles, and can be distributed with considerably less diamond particles on the cutting surface 4.
As just described, when diamond particles according to cutting surface during with different CONCENTRATION DISTRIBUTION, not only the cutting speed of cutting element reduces, and reduce the service life of cutting element.That is, in working angles, the decrease in efficiency of diamond particles.
As United States Patent (USP) 5,518,443 disclosed contents have been carried out trial many times in order to address the above problem the inventor.
United States Patent (USP) 5,518,443 disclose a kind of technology, and this technology can be by being randomly dispersed in diamond particles on the segment of cutting and high concentration region being set continuously and low concentration region improves cutting speed and service life towards cutting direction.
As United States Patent (USP) 5,518,443 is disclosed, when the high concentration region with diamond particles is connected with low concentration region when being provided with, in high concentration region, many diamond particles are exposed on the cutting surface, therefore, for the load step-down that each diamond particles bore, postponed the wearing and tearing of diamond particles, and increased service life.Do not having or almost do not having in the zone of diamond particles, diamond particles wears away easily, thereby because the quick wearing and tearing of metal dust increase cutting speed.
But for aforesaid United States Patent (USP) 5,518,443, diamond particles random distribution and suitably not separating in high concentration region causes producing inhomogeneous concentration.Therefore, form restriction in cutting speed and service life to improving.
In order to solve the isolating problem of diamond particles, a kind of diamond particles pattern process has been proposed, as shown in Figure 2.
Fig. 2 shows an example of the segmentation diamond tool 20 that is formed with the diamond particles pattern.
As shown in Figure 2, diamond particles is forming pattern or is distributing regularly in each section 21,22 in each section 21,22.
If workpiece utilizes described section to cut, diamond particles evenly distributes on cutting surface and evenly at interval, makes a diamond formation evenly general.Therefore, all diamond particles have participated in cutting constantly in machining, thereby have improved the efficient of machining.
But, if when the above-mentioned pattern process of mentioning is applied on the segment of cutting of the low concentration region with diamond particles (the diamond particles number on the per unit volume of section), then form restriction in cutting speed and service life to improving.
United States Patent (USP) 6,110,031 provides a kind of technology, and this technology is by improving cutting speed and service life forming high wear-resistant skin on the both sides and form internal layer between skin.Internal layer be arranged in cutting direction be distributed with regularly in direction perpendicular to cutting direction height resistance to wear the part and the relative low part of resistance to wearing.
But at United States Patent (USP) 6,110, in 031, high concentration region in internal layer and low concentration region distribute across described section equably in cutting direction or on perpendicular to the direction of cutting direction.As a result, at low concentration region, can not be enhanced service life, and at high concentration region, because adjacent to the low district of resistance to wearing, so the projecting height of diamond particles can not maximize.Therefore, the effect of the cutting speed that formation is good just becomes nonsensical.

Summary of the invention
With reference to accompanying drawing, will be elaborated to preferred embodiment of the present invention now.
Fig. 3 shows an example of segment of cutting of the present invention.
As shown in Figure 3, segment of cutting 100 of the present invention comprises multiple row abrasive grain 101, and wherein abrasive grain 105 is towards the cutting direction setting.Segment of cutting 100 according to the present invention comprises the some abrasive grains that are arranged on along in the multiple row of cutting direction extension.Abrasive material row 101 are placed side by side and stacked vertically with respect to cutting direction mutually across cutting direction.
Preferably, the number of abrasive material row 101 is 4 at least.
In working angles, high concentration region 110a bears big cutting load.Therefore, if be arranged among the outer row 101a of a side row and adjacent in distance D out between the row 101b too big, then outer abrasive material is listed in that the side towards segment of cutting comes off in the working angles, thereby makes the outside of abrasive material row 101 can not proceed to cut.As a result, preferably, be listed as outward one among 101a row and adjacent in distance D out between the row smaller or equal to 2.0 times of abrasive grain average diameter.
Otherwise too big as if the distance D between the interior row 101b that is arranged between the outer row 101a, the part that then is positioned at the segment of cutting of the middle no abrasive grain of abrasive material row can be recessed dearly, thereby abrasive grain is easy to come off, and can reduce the service life of cutting element.Therefore, outside distance D between the interior row 101b of row between the 101a preferably smaller or equal to 4.0 times of abrasive grain average diameter, or more preferably be 1.3 to 2.5 times of abrasive grain average diameter.
Abrasive material is listed as from cutting surface 111 stacked vertically.
As firm explanation, without any abrasive grain, then low concentration region 110b also can be without any abrasive grain as if low concentration part 1012a, 1012b.
Along cutting direction, high concentration region 110a and low concentration region 110b alternately occur.
Shown in Fig. 3 a, on cutting surface, low concentration region 110b is a polygon, is in particular rectangular profile 120a, and shown in Fig. 3 b, low concentration region 110b is a polygon, is in particular parallelogram profile 120b.
Preferably, the length L of high concentration region 110a is 0.3 to 2.0 with the ratio L/A of low concentration region 110b length A.
Along cutting direction, high concentration region 110a and low concentration region 110b alternately occur.
At least one high concentration region 110a and a low concentration region 110b should be arranged respectively.
According to the present invention, high concentration region 110a on the cutting surface of segment of cutting and low concentration region 110b allow to cut under low loading condition.Thereby in working angles, cutting element is subjected to low the impact, is subjected to less vibration and noise and make.Particularly, if high concentration region 110a on the cutting surface of segment of cutting and low concentration region 110b have suitable length and number, then the present invention will improve cutting speed, and this kind situation will make an explanation hereinafter.
Fig. 4 shows when utilizing the segment of cutting cutting workpiece that is provided with abrasive grain on it regularly, the outstanding situation of the abrasive grain of being seen from the segment of cutting side.Fig. 4 (a) shows the segment of cutting that the concentration district does not have variation, and Fig. 4 (b) shows the vicissitudinous segment of cutting in concentration district.
Shown in Fig. 4 (a), without any the segment of cutting that changes, its all abrasive grain is all outstanding with almost equal height for having diamond particles that rule is provided with but in the concentration district.
In this case, on cutting direction, the afterbody that the outstanding abrasive grain that is positioned at segment of cutting rear portion place is subjected to the front abrasive grain buries lid, and bears less cutting load.As a result, the sharp edges of abrasive grain becomes smooth, has reduced cutting speed.
Simultaneously, shown in Fig. 4 (b), for include the high concentration region that replaces mutually and the segment of cutting of low concentration region according to the present invention, abrasive grain A, the B, the C that are positioned at front, concentration district show outstanding base altitude h.
This is because at low concentration or do not have to wear and tear in the zone of diamond particles serious relatively, it is high outstanding to make abrasive grain in the high concentration region front become.
Equally, on cutting direction, it is less that the afterbody that the abrasive grain that is positioned at the high concentration region rear portion is subjected to being positioned at the abrasive grain of front buries lid, thereby improved the cutting speed of each abrasive grain.
That is, in the cutting element of same diameter, cutting speed is along with the proportional increase of the number of segment of cutting.The present invention is by realizing having the effect of a plurality of sub-segment of cutting to improve cutting speed as segment of cutting.
In addition, for the polygon profile of low concentration region 110b, this profile can have at least one side and tilt towards the direction perpendicular to cutting direction.This structure decrease the impact that produces of the possible serious interruption that causes owing to the high concentration region 110a that replaces mutually and low concentration region 110b.
Equally, the design for high concentration region and low concentration region influences and will make an explanation hereinafter cutting speed.
Typically, imagination is when utilizing high-power machine to cut hard workpiece with the cutting speed of quickening, and abrasive grain is the bulky grain abrasive grain.In the case, can improve in cutting speed and service life by ratio and the increase high concentration region number that reduces high concentration region.
In addition, preferably, should increase the number of the abrasive material row in the section of being layered in, thereby dwindle the distance D out between outer row and the interior row, and the distance D between the row in dwindling, so that groove can be too not dark.
Therefore, the abrasive grain of segment of cutting and mean concentration should determine according to working condition, machine and workpiece, tackles the number of abrasive material column number, high concentration region and low concentration region and length and local concentration then and determine.
Fig. 5 shows the abrasive grain of segment of cutting from the stacked vertically example of cutting surface.
As shown in Figure 5, in the segment of cutting 200 in the present invention, the some abrasive grains and the abrasive material that are arranged in a plurality of row that extend along cutting direction are listed as from cutting surface stacked vertically.
Preferably, the abrasive material row adopt stacked in the following manner: in the cutting workpiece process, new abrasive grain 205b can be outstanding in initial outstanding abrasive grain 205a.
In Fig. 5, digital 210a refers to high concentration region, and digital 210b refers to low concentration region.
As shown in Figure 5, abrasive material is listed as from cutting surface stacked vertically, thus abrasive grain can be when cutting workpiece with even interval and to have predetermined pattern ground outstanding continuously.
Fig. 6 shows another example of segment of cutting of the present invention.
In the present invention, shown in Fig. 6 (a), abrasive material row adopt stacked in the following manner: the low concentration part of sinking abrasive material row perpendicular to the direction of cutting surface corresponding on cover the abrasive material row high concentration partly place.
As just in the described stacked situation, on cover and should be 1/2 to 2/3 of abrasive grain size apart from d between abrasive material row and the sinking abrasive material row.
