Abstract
The utility model provides a wear-proof crusher hammer which comprises a hammer handle and a hammer body, wherein the working surface on the hammer body comprises a base material layer and a composite layer; and the composite layer comprises base material metal and hard ceramic grains; and the ceramic grains are uniformly distributed in the base material metal. With the adoption of the wear-proof crusher hammer, the hard ceramic grains are diffused and distributed inside a foam model, the bonding strength of base material molten metal and the hard ceramic grains are improved, and the molten metal can conveniently permeate among the grains; and the wear-proof crusher hammer is high in surface mass and dimensional accuracy and good in overall performance, and can be widely applied to wear-proof fields of mine, electric force, metallurgy, coal, building materials and the like.
Description
Technical field
The utility model relates to a kind of grinder hammerhead, particularly a kind of anti abrasive grinder hammerhead.
Background technology
Hammer mill is industries such as metallurgy, mine, building materials and electric power disintegrating apparatus commonly used; Tup is wherein main vulnerable part; Its operation principle is to rely on the tup of rotation at a high speed to clash into the purpose that gets into the material in the cracking cabin and reach comminuting matter, and the main failure forms of tup is wearing and tearing and fracture.For a long time, the wear resistence of grinder hammerhead is poor, and service life is short, changes frequently, is the key factor of restriction material crush efficiency.Therefore development of new hammer head material and shape technology becomes problem demanding prompt solution the service life of improving tup.
The grinder hammerhead of present domestic employing mainly contains the monoblock cast tup: related material have potassium steel (Mn13) (CN200710152334.0), medium carbon alloy steel (CN1050566A), abrasion resistant Mn-W-Ti casting steel (CN1068637C), low-alloy steel (40CrMnSiMoRe), high carbon chromium nickel-molybdenum alloy steel and rich chromium cast iron etc.; Composite hammer head: comprise double-fluid double metal composite casting tup, castingin inlay or the box-like tup of soldering group (CN200320116032.5, CN91218917.7, CN201316649Y, CN93245615.4, CN2257218Y, CN2564248Y, CN2283517Y); Surface overlaying or whole built-up welding tup (CN1419990A, CN1517173A); CN101530904A explains that mainly the method with centrifugal casting obtains the apparatus and method that WC particle strengthens the base steel composite material tup; CN201300204Y discloses the method that adopts hot composite casting tup, and CN200920088270.7 discloses a kind of compound wear-resisting alloy hammer head; CN101314145A discloses a kind of grinder hammerhead with ceramic wearing coat with disappearance mould and casting infiltration preparation; CN200510096149.5 discloses a kind of iron base composite material tup and casting method thereof; CN200510043187.4 discloses a kind of WCp and has strengthened the iron-based skin layer composite material with the complexing agent technology; CN95113785.9 discloses a kind of local composite material and manufacturing approach thereof.For monoblock cast steel alloy tup, though it has high obdurability, in running, be difficult for rupturing, because the integral hardness of tup is lower, and the M in the tissue
3The hardness of carbide such as C is not enough to resist the thump abrasive action of material, so wear no resistance, service life is short.Although people attempt to improve the wear resistence of tup through adjusting measures such as alloying component and improvement Technology for Heating Processing, its result manufacturing cost often significantly increases, and the wear resistence raising is very little; For monoblock cast rich chromium cast iron tup, easy fracture then is the main cause of its premature failure in the running.And the top composite hammer head of mentioning, the complicated process of preparation that has, controllability are not strong, and composite bed comes off under percussion during the actual use that has, does not have the due wear-resisting effect of composite bed.
The utility model content
The purpose of the utility model is to provide a kind of can satisfy the high performance grinder hammerhead that uses under the complex working conditions such as various wearing and tearing, impact.
The utility model provides a kind of so anti abrasive grinder hammerhead; Form by hammer handle and hammer body; Said hammer working face (zone that withstands shocks and wear and tear) on one's body is made up of substrate layer and composite bed; This composite bed is made up of substrate metal and hard ceramic particles, and wherein hard ceramic particles is uniformly distributed in the substrate metal.
The spacing of said hard ceramic particles is 375～2000 μ m.
Hard ceramic particles evenly distributes in the tup working region in this tup that has a composite bed, to play the effect of dispersion-strengtherning, improves its shock-resistant and anti-wear performance.Hard ceramic particles is a kind of in aluminium oxide, carborundum, tungsten carbide, silicon nitride, the titanium nitride or any several kinds; Substrate metal is steel or iron, like ordinary carbon steel, steel alloy, potassium steel, casting pig or spheroidal graphite cast-iron.Adopt disappearance mould foaming technique, prepare hard ceramic particles equally distributed tup working face Foam Pattern between bead, the Foam Pattern with this apperance and other parts of tup is spliced into complete tup then; Behind the moulding by casting, the promptly disposable ceramic particle that obtains strengthens the local compound grinder hammerhead of iron and steel base.
Compare with prior art, the utility model has following beneficial effect:
The utility model is by disappearance mould foaming technique; The hard ceramic particles disperse is distributed in bubbles model inside; Improved the bond strength of substrate metal liquid and hard ceramic particles, be beneficial to molten metal, made the tup of the utility model preparation have higher surface quality and dimensional accuracy in intergranular infiltration; Overall performance is good, can be widely used in wear-resisting fields such as mine, electric power, metallurgy, coal, building materials.
