Abstract
The utility model discloses a compound-type diamond tool bit which comprises a diamond sintered body and an electroplate diamond layer, wherein the electroplate diamond layer is connected with the diamond sintered body in a compound mode, and the diamond sintered body is further provided with a cemented carbide layer in a compound mode. The compound-type diamond tool bit is low in cost, simple in structure, good in cutting effect, high in rigidity, good in intensity and tenacity, heat-proof and corrosion-resisting, and capable of prolonging service life.
Description
Technical field
The utility model relates to a kind of sintered body composite diamond instrument, particularly relates to a kind of cutter head that is provided with the electroplated diamond layer.
Background technology
At present, diamond tool bit is powder sintering type substantially, because technological reason, the wood interior porosity of this kind cutter head is about 8%-10%, and the diamond anti-impact force is relatively poor.
For example the patent No. is CN03266263.7, and publication number is the Chinese patent " composite diamond tool insert " of CN2654258.Disclose a kind of composite diamond tool insert, comprised the sinter from metal powder diamond segment, the electroplated diamond layer.It is characterized in that the electroplated diamond layer is positioned on the sintered body diamond segment.The weak point of this patent is, after long-term use wearing and tearing, causes the cutting effect variation of cutter head, wearability and corrosion-resistant, and service life is short.
The utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, proposes a kind of composite diamond tool bit.The utility model adopts diamond sinter also to be compounded with hard alloy layer, having overcome prior art exists owing to after the long-term use wearing and tearing, the cutting effect variation that causes cutter head, wearability and corrosion-resistant, the technical problem that service life is short, cost is low, simple in structure, cutting effect is good, and hardness is high, intensity and good toughness, heat-resisting, corrosion-resistant, has prolonged service life.
The utility model is realized by the following technical solutions:
A kind of composite diamond tool bit comprises diamond sinter and electroplated diamond layer, and described electroplated diamond layer and diamond sintering bluk recombination is characterized in that: described diamond sinter also is compounded with hard alloy layer.
Described hard alloy layer is arranged on the surface of diamond sinter.
Described hard alloy layer is arranged between electroplated diamond layer and the diamond sinter.
The utility model compared with prior art, its advantage is:
1, the utility model adopts diamond sinter also to be compounded with hard alloy layer, having overcome prior art exists owing to after the long-term use wearing and tearing, the cutting effect variation that causes cutter head, wearability and corrosion-resistant, the technical problem that service life is short, cost is low, simple in structure, cutting effect is good, and hardness is high, intensity and good toughness, heat-resisting, corrosion-resistant, has prolonged service life.
2, the utility model adopts hard alloy layer to be arranged on the surface of diamond sinter, and hardness is high, intensity and good toughness, heat-resisting, corrosion-resistant, has prolonged service life.
3, the utility model adopts hard alloy layer to be arranged between electroplated diamond layer and the diamond sinter, the wearability between electroplated diamond layer and the diamond sinter, and effect is remarkable.
