Abstract
The wear resistant part consists of matrix, hard alloy layer and middle copper-base solder adhesive layer, which is heated to adhere the matrix and hard alloy layer. Compared with available composite metal wear resistant part, the said part has 2-10 times higher strength and hardness, 65% higher density, 3 times longer service life and 10% lowered cost.
Description
The present invention relates to a kind of hard alloy wear resistant parts and be used to make the method for this wearing piece.
Existing alloy wear-resisting spare mainly adopts rich chromium cast iron, and ni-hard cast iron or carbide alloy manufacturing form.Rich chromium cast iron or ni-hard cast iron are widely used in large-scale vulnerable part, but hardness not high (≤RHC60), the institutional framework inequality, anti-wear performance is undesirable.If all adopt the carbide alloy manufacturing, anti-wear performance is no doubt good, but involves great expense, and large-scale easy mill spare prior art can not produce, and therefore, has occurred a kind of composite metal anti-abrasive spare based on casting carbon tungsten carbide particle in recent years, has solved above-mentioned several problem.But the alloy-layer that tungsten carbide particle and solder are formed is short texture not only, and density is little, and hardness is disperseed, and greatly reduces the wear-resisting service behaviour of tungsten carbide, makes life of product and price more little than improving, and the end can obtain bigger economic benefit.And its intensity is low, can not be applicable to the working environment that impact is strong and bump is serious.
The object of the present invention is to provide a kind of hard alloy wear resistant parts, can improve its density and hardness, it is few to reach wearing and tearing, greatly prolong working life, can improve the intensity of workpiece again, to be adapted to impact and clash into serious working environment, product working life and price ratio are improved greatly, obtain bigger economic benefit.
The needed parent that is shaped as is made and formed to hard alloy wear resistant parts of the present invention with iron material, steel or other ordinary metallic materials, to be one deck add glue by heavy metal powder such as tungsten-carbide powder, cobalt dust, nickel by powder or titanium powder forms the hard alloy layer of required shape through molded and sintering for the inner face of parent or outside wearing layer, is the copper base solder tack coat between parent and the hard alloy layer.The content of the tungsten-carbide powder in the hard alloy layer, cobalt nickel, titanium, tantalum powder etc. can require to adopt different composition proportionings according to different intensity and hardness, and copper base solder adopts manganese-copper alloy and its manufacture usually.
The manufacture method of hard alloy wear resistant parts is:
1) makes parent according to the shape and the size of workpiece with iron and steel or other ordinary metallic materials;
2) according to job requirement design workpiece working face wearing layer thickness and distribution thereof, adopt heavy metal powder such as tungsten-carbide powder, cobalt dust, nickel by powder or titanium powder add glue laminated make shape, again through sintering carbide alloy into;
3), adopt common metal or other exotic materials to be processed into pattern, and be stained with carbon class material in the pattern inboard according to the shape of above-mentioned requirements;
4) carbide alloy of moulding is bonded on the carbon class material surface, lean against on the parent together with whole pattern, perhaps, the moulding carbide alloy is leaned against earlier on the parent, again by last pattern, fixation then, and it is tight the welding of the seam of side and bottom, place in upper ends copper base solder and integral body again and be heated to the copper base solder fusing in the stove, carbide alloy and parent are bonded together, formation one deck composite hard alloy wearing layer.
Owing to adopt the tungsten-carbide powder alloy (to require the composition proportioning of alloy different according to varying strength and hardness, mainly contain tungsten carbide, cobalt, titanium, nickel, copper, vanadium, tantalum etc.) become wear-resisting phase through the high pressure dense sintering, its hardness is HRA80～93, and intensity is 100～280kg/mm
3, density 10～15.5/cm
3, thereby, still be that the performance such as hardness, intensity, density of tungsten carbide particle alloy wear-resisting phase all exceeds much than high ferrochrome, ni-hard cast iron.This product is compared with prior art products composition metal (cast tungsten carbide) wearing piece: 1. large-scale workpiece has solved the pattern problem on deformation when high temperature brazing; Produce bubble steam vent and other blemish problems when 2. having solved high temperature brazing; 3. product strength and hardness improve 2～10 times, and working life improves more than 3 times; 4. product appearance is neat attractive in appearance, is convenient to detect various performances; 5. because solder not as wear-resisting phase, thereby can deduct aging technique, improve the plasticity and the toughness of solder, reduced cost; 6. improve more than yield rate reaches four one-tenth; 7. the price ratio has reduced by 10% the life-span.
Below in conjunction with accompanying drawing hard alloy wear resistant parts of the present invention and manufacture method thereof are described in further detail:
Fig. 1, be that hard alloy wear resistant parts pendulum-type high speed grinding roller cross section cuts open figure;
Fig. 2 is interior mill formula hard alloy wear resistant parts generalized section.
Fig. 3 is a part plan type hard alloy wear resistant parts generalized section.
Fig. 4 is a square hard alloy wear resistant parts generalized section.
Fig. 5 is a fixing pattern schematic diagram in the hard alloy wear resistant parts pendulum-type high speed grinding roller soldering manufacture process.
Among Fig. 1 to Fig. 5,1 parent of making for metal material; 2 is hard alloy layer; Intermediate layer 3 is the copper base solder tack coat; 4 is pattern; 5 is carbon class material; 6 is steel plate; 7 is copper base solder.Parent 1, hard alloy layer 2, pattern 4 can be processed as required and be made into various needed shapes (as plane, square, arc, sphere, platform shape etc.).Hard alloy layer divides two kinds of ways to manufacture: 1. small workpiece can directly be suppressed a formation of lots; 2. big workpiece need suppress polylith and piece together moulding again.In Fig. 5, with all-purpose adhesive carbon class material is bonded on the pattern medial surface earlier, the back is bonded at carbide alloy on the carbon class material, be combined together with parent then, weld the bottom, and weld a hopper in the upper end with steel plate, good seal, drop into copper base solder, place stove to be heated to 800～1200 ℃, the solder fusing is soaked amass in parent and the carbide alloy, be incubated 10～200 minutes, take out the cold back of stove, and pattern is sloughed, and promptly is bonded with one deck hard alloy abrasion-resistant layer on the parent working face securely.
