Description
Technical field
The utility model relates to a kind of abrasion-proof structure, particularly relates to a kind of composite metal anti-abrasive structure.
Background technique
Metal wear resistant material probably has following several both at home and abroad at present: manganese steel plate, rare earth Cr-Mo steel, diamondite wear resistance electrode (welding wire), Tungsten Carbide Surfacing abrasion-proof composite plate, Surface Treatment with Plasma, German bit gram (betek) wear-resistant block etc.
More or less all there is certain defect in the technological method of several high-abrasive materials above, and good shock resistance does not reach requirement to show as wear resistance.If wear-resisting property and shock resistance all can meet the requirements of, surface finishment is inadequate so, and welding performance is also poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of composite metal anti-abrasive structure, and its wear-resisting property and shock resistance all can meet the requirements of simultaneously, have also improved surface finishment and welding performance.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of composite metal anti-abrasive structure, it is characterized in that, it comprises YG11 type hard alloy columnar and NM400 type wear-resisting steel plate, multiple YG11 type hard alloy columnars adopt cold-press process to be pressed in NM400 type wear-resisting steel plate, YG11 type hard alloy columnar upper end is concordant with NM400 type wear-resisting steel plate surface, the column pitch of the line space of YG11 type hard alloy columnar and YG11 type hard alloy columnar is the diameter of the YG11 type hard alloy columnar of twice, the even Heterogeneous Permutation of YG11 type hard alloy columnar between adjacent lines and adjacent columns.
Positive progressive effect of the present utility model is: wear-resisting property of the present utility model and shock resistance all can meet the requirements of simultaneously, have also improved surface finishment and welding performance.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model composite metal anti-abrasive structure.
Fig. 2 is that in the utility model, the dislocation of YG11 type hard alloy columnar and NM400 type wear-resisting steel plate is arranged and the schematic diagram of fricting movement direction (direction of arrow).
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the utility model composite metal anti-abrasive structure comprises YG11 type hard alloy columnar 1 and NM400 type wear-resisting steel plate 2, can adopt cold-press process to be pressed in NM400 type wear-resisting steel plate multiple YG11 type hard alloy columnars, and it is concordant with NM400 type wear-resisting steel plate surface to keep being pressed into rear YG11 type hard alloy columnar upper end, the column pitch of the line space of YG11 type hard alloy columnar and YG11 type hard alloy columnar is the diameter (A) of the YG11 type hard alloy columnar of twice, the even Heterogeneous Permutation of YG11 type hard alloy columnar between adjacent lines and adjacent columns, to reach high wear-resisting effect.
YG11 type hard alloy columnar is the one in die steel, specifically belongs to the cemented carbide of Tungsten carbite class, and without heat treatment, inside and outside hardness is all consistent.For large batch of production, be applicable to making press tool, as materials such as punching silicon steel sheet, Q195, SPCC and need mould that wear resistance is good etc.The parameter of YG11 type hard alloy columnar is as follows: average grain: 1.2, and middle particle; Density: g/cm3:13.4-13.8; Resistance to flexure: ≈ 3400; Hardness: >=88HRA: chemical composition: WC:89%, CO:11%.
The concrete structure of NM400 type wear-resisting steel plate is as follows: N is that resistance to (nai) M is first phonetic alphabet of (mo) two Chinese characters, and 400 represent the average Brinell hardness of this steel plate.Steel plate has good cold-bending property, is applied to the operating mode of resistance to wearing.Meanwhile, possess extraordinary weldability, its mechanical property is 3 times to 5 times of ordinary low-alloy steel plate; Can significantly improve the wear resistance of mechanical associated components, therefore improve mechanical working life, reduce production costs, this product surface hardness reaches 360-450HB conventionally.
Because YG11 type hard alloy columnar is smooth being pressed in NM400 high-strength abrasion-proof steel plate, so it has well ensured the flatness of steel plate, and then steel plate in use also can be worn and torn on surface uniformly.Need to produce different-thickness according to client, the difform molding product of bending and molding, can carry out welding operation with common welding machine at the construction field (site), and efficiency is high.The utility model can be widely used in engineering machinery, mining equiment etc. need to strengthen wear-resisting and impact-resistant position.For example: the Wear-resistant Treatment of the scraper bowl of excavator-type shovel clamshell excavator, power shovel, forklift, coal mining machine roller blade, guide slip shoe, cutting head of roadheader, scraper conveyor, coal washery blanking port etc.The utility model takes full advantage of high abrasion and the impact resistance of YG11 hard alloy columnar; combine again comprehensive mechanical property, welding performance and the low temperature impact properties of NM400 type wear-resisting steel plate; well combine with the novelty of product again; when significantly reducing, the cost of raw material, cost of production, welding cost increase substantially the wear and shock-resistant performance of material; and then the working life of having improved product for user; reduce the maintenance outage that maintenance brings, reduce accordingly the input of fund.
The wear resistance of this abrasion-proof structure is the more than 90 times of carbon structural steel (Q235).Be main special wearing and tearing testing installation test through adopting quartzy emery wheel, in the time that the wear testing time is 60 minutes, the wearing layer wearing and tearing weight of this abrasion-proof structure is 3.5 grams, and its relative two planar smoothness reach 0.01mm, and the perpendicularity of adjacent two planes reaches 0.025mm.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
