Description

The diamond abrasive wheel

The utility model is a kind of diamond abrasive wheel, and the diamond abrasive that refer to a kind of efficient height especially, is difficult for wearing away is taken turns.

Expanded material such as the end or sole or rubber are after half-formed in the footwear, need to take turns its surface grinding to required size by diamond abrasive, to present its high texture, and the conventional diamond abrasive wheel mostly as shown in Figure 5, abrasive wheel 30 is a cylindrical shaped body, an end and become umbellate form to bring shape together wherein, and the center of abrasive wheel 30 is provided with the perforation 31 that the main shaft of confession grinder passes, and the periphery of abrasive wheel 30 is interval with guide groove 32, then the abradant surface 33 that is equipped with diamond dust except guide groove 32, thus, after abrasive wheel 30 is inserted in the main shaft of grinder with its perforation 31, start grinder and can drive abrasive wheel 30 rotations, grind.

Yet this kind diamond abrasive wheel but has easy to wear and inefficient defective, and its reason is:

1, each the guide groove 32 root edge shape because of diamond abrasive wheel 30 have an inclined plane, cause the opening part of each guide groove 32 to be the abrasive tip 321 of acute angle, and in the process of grinding, acute angle abrasive tip 321 very easily weares and teares, and the service life of having reduced abrasive wheel 30.

2, the effect of guide groove 32 tool dust leads and grinding, and its shape is that bottom land is made as an inclination angle, cause a wherein end angle of guide groove 32 openings to be acute angle, this acute angle is abrasive tip 321, and it is convenient for grinding, the end angle of abrasive tip 321 also is equipped with diamond dust, when 30 pairs of article of abrasive wheel carry out grinding operation, be to grind with the abradant surface 33 that is equipped with diamond dust, and partly waste material is promptly got rid of from guide groove 32, but in rotary course, grind the waste material utmost point in being equipped in guide groove 32 root edges that are the inclination angle, block guide groove 32 and influence its dust lead effect.

From the above, the conventional diamond abrasive wheel is not only wasted material, and cost height, influence its market competitiveness, so No. 86200165 " structural improvement of diamond abrasive wheel " utility model patent case of this creator's Taiwan patent, it is the root edge formation arc depression with the guide groove of abrasive wheel and guide channel, and the opening part two ends that make guide groove and guide channel all form angle abrasive wheel in obtuse angle, and then delay wear rate, and improve the chip removal effect of abrasive wheel, but still there is following shortcoming in this case:

Though this case can delay wear rate and increase the chip removal effect, but and when having protrusion when the surface irregularity of abrasive material, this abrasive wheel is still the same with traditional abrasive wheel must constantly to be ground protrusion, can be with surface rubbing, thus, the diamond dust abradant surface of abrasive wheel soon promptly can loss, and need be changed, and grinding efficiency is extreme difference also, and improved necessity is in addition arranged.

The diamond abrasive wheel that the utility model main purpose is to provide a kind of grinding efficiency height and slows down abrasion speed.

For achieving the above object, the utility model is taked following measure:

The utility model is embedded a blade in the abrasive tip of abrasive wheel, the height of this blade is lower than abradant surface, when the abrasive article surface, this blade does not influence the grinding effect that is produced with abradant surface, but when article surface has protrusion, this blade that is positioned at abrasive tip can be implemented the work of striking off, and then grinds with abradant surface.Concrete structure of the present utility model is as follows:

Diamond abrasive wheel of the present utility model, the periphery of diamond abrasive wheel is the abradant surface that is equipped with diamond dust, be interval with the concave type guide groove in periphery in addition, the root edge of guide groove also is circular arc or square depression, all the other are partly then for being equipped with the abradant surface of diamond dust, it is characterized in that: an end of guide groove is an abrasive tip, is embedded with a blade on the abrasive tip.

Described diamond abrasive wheel is characterized in that described blade is a little less than the diamond dust surface.

The utility model compared with prior art has following effect:

1, raises the efficiency:, carry out grinding and polishing with the abradant surface that is equipped with diamond dust again, its grinding efficiency height owing to when article surface has protrusion, can give earlier by the blade that is positioned at the guide groove abrasive tip and striking off.

2, not easy to wear: as because the utility model is to utilize blade to carry out the operation of striking off to protrusion, to be not as tradition, to grind, more can to avoid the abrasion of abrasive tip, and prolong its service life with abrasive tip with diamond dust.

3, reduce cost: owing to implement that the utility model can be raised the efficiency and not easy to wear, so can reduce cost.

Further specify specific structural features of the present utility model below in conjunction with drawings and Examples.
