Abstract
The invention relates to the technical field of abrasive tools, in particular to an abrasion-resistant tool. The abrasion-resistant tool comprises a supporting basal body and an ultrahard working layer arranged on the supporting basal body, a continuous bonding interface is formed between the supporting basal body and the ultrahard working layer, and the ultrahard working layer at least comprises two working layer bodies different in abrasion resistance and thickness. The continuous bonding interface is formed between the supporting basal body and the ultrahard working layer, and the supporting basal body and the ultrahard working layer are firmly bound, high in strength and not easily separated due to impact. The ultrahard working layer at least comprises the two working layer bodies different in abrasion resistance and thickness. Due to the arrangement of the different working layer bodies, when the abrasion-resistant tool works, using efficiency of multiple functional regions can be achieved, comprehensive high abrasion resistance and impact resistance are possessed, and using requirements are met. The abrasion-resistant tool is simple in structure, reasonable in design, and convenient to produce and manufacture, and meanwhile high abrasion resistance and impact resistance of the abrasion-resistant tool can be guaranteed.
Description
Technical field
The present invention relates to milling tool technical field, be specifically related to a kind of wear resistant tools.
Background technology
Wear resistant tools is in machining, oil drilling, and various industry extensive use.For the probing of deep-sea and firm hard formation, PDC composite teeth especially has its unique advantage.Reach high performance drilling results, PDC composite teeth need to have extremely strong combination property.These performances comprise abrasion resistance, shock-resistant, and high thermal stability.PDC composite teeth is comprised of two parts conventionally: diamond support matrices and working lining.For reaching high abrasion resistance, need under HTHP, suppress and form; In HTHP pressing process, metallic cobalt is extruded from matrix, sweeps more diamond layer, forms high-strength diamond bonding, after this reduces temperature and pressure, completes sintering.But, because the diamond layer after sintering curing and hard alloy layer have larger thermal expansion coefficient difference, often cause cooled stretching residual stress.Greatly reduced thus the impact resistance of instrument, and practical probing performance.
In order to improve the impact property of PDC composite sheet, non-planar interface is widely used in the design of composite sheet and matrix, and these are all round nonplanar interface.But these design all generally for commaterial microstructure, mostly there is single performance advantage, or wear-resisting, or shock-resistant.Cannot reach the multiplex effect of a tooth.In actual probing, in order to meet the requirement of using, often need to use two or more composite sheet.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of reasonable in design, there is the wear resistant tools of different performance, different-thickness working lining, it has wear-resisting working lining and shock-resistant working lining simultaneously, meets instructions for use.
Realize technical scheme of the present invention as follows:
Wear resistant tools, comprises support matrices, is arranged at the superhard working lining on support matrices, between support matrices and superhard working lining, forms continuous bonded interface, and described superhard working lining at least comprises the working lining of two different anti-wear performances, different-thickness.
Further, described continuous bonding cross section is the relief highly differing.
Further, the thin crystallite dimension material of employing that described working lining thickness is little is made.
Further, the thin crystallite dimension material of employing that described working lining thickness is large is made.
Further, described superhard working lining adopts polycrystalline diamond abrasive compact to make, and support matrices adopts Hardmetal materials to make.
Adopt such scheme, between support matrices and superhard working lining, formed continuous bonded interface, strong bonded between the two, intensity is high, is difficult for because impact separates, and superhard working lining at least comprises the working lining of two different anti-wear performances, different-thickness.Owing to comprising different working linings, when wear resistant tools is worked, the effective utilization that it can reach several functions region, has comprehensive high abrasion and impact resistance, meets instructions for use like this.The present invention is simple in structure, reasonable in design, is convenient to manufacture, and can guarantee high abrasion and the impact resistance of wear resistant tools simultaneously.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to Fig. 1, wear resistant tools, comprise the support matrices 1 that adopts Hardmetal materials to make, be arranged at the superhard working lining 2 that adopts polycrystalline diamond abrasive compact to make on support matrices, between support matrices and superhard working lining, form continuous bonded interface 3, superhard working lining comprises the working lining 4,5 of two different anti-wear performances, different-thickness.Wherein, continuous bonding cross section is the relief highly differing.The thin crystallite dimension material of employing that working lining thickness is little is made.The thin crystallite dimension material of employing that working lining thickness is large is made.
The shape of the different support matrices shown in Fig. 2,3, the shape of its upper surface is not identical, adopts difform relief.
Fig. 4 shows the wear resistant tools with Fig. 3 support matrices structure, and its working lining 6,7 parts have different wear-resisting and resistances to impact, and the average thickness of working lining 6 is little has high abrasion resistance, and the average thickness of working lining 7 is high, has high resistance to impact.
Fig. 5 shows the shape of support matrices in another, Fig. 6 shows the wear resistant tools that adopts Fig. 5 support matrices, and working lining 8,9 has different wear-resisting and resistances to impact, and working lining 8 average thickness are little has high abrasion resistance, working lining 9 average thickness are high, have high resistance to impact.
At this, it is pointed out that the bonded interface shape between support matrices and superhard working lining, can need to be arranged to difformity according to difference, as long as it can realize the working lining of different-thickness, as waveform.
