Technical field
The present invention relates to the machine components manufacturing, particularly shock-resistant member and manufacture method, and the hammer body that adopts this method to produce.
Background technology
Existing shock-resistant parts, for example hammer body of disintegrating machine and sintering bridging plate, manufacture method mainly is three kinds of monoblock cast, solid forging and whole built-up welding.Monoblock cast is owing to have defectives such as shrinkage cavity, segregation in the foundry goods, and the compactness of tissue is poor, influence the wearability of foundry goods, is subjected to the restriction of casting technique simultaneously, and material therefor hardness can not be too high, otherwise foundry goods is easy to generate crackle when casting; Solid forging is same because the restriction of Forging Technology, hardness can not be too high, otherwise be easy to generate crackle, adopt technique for overlaying, dense internal organization, though avoided defectives such as parts internal shrinkage that casting method brings, segregation, material therefor hardness can not be too high, otherwise welding process very easily produces cold crack.If will use with the parts installation of crackle, then the crackle that may form in original crack and the use is easily expanded, and forms through wall flaw, causes parts working portion bulk to come off, and effectively work quality significantly reduces, and comprehensive use cost improves.
Summary of the invention
The objective of the invention is to, a kind of shock-resistant member and manufacture method are provided, the crackle of described member is difficult for forming through wall flaw, is difficult for causing the working portion bulk to come off.
The object of the present invention is achieved like this: a kind of shock-resistant member is provided, it is characterized in that, comprise metallic framework and packing material, closely be connected between metallic framework and the packing material.
Described member profile is cuboid, cone or irregular geometry.Described skeleton is constituted by in sheet material, bar, the special-shaped material any one or a few; Described packing material is a high hardness material; Form metallurgical binding between metallic framework and the packing material.
The present invention also provides a kind of shock-resistant method for manufacturing component, it is characterized in that, may further comprise the steps:
A. make skeleton with metal material according to the shape of parts, form rough three-D profile;
B. fill the high rigidity metal material in metallic framework, the two is combined closely.
Described metal material is a steel.Described high hardness material is high abrasion, high rigidity metal.Fill method comprises following arbitrary at least: welding, casting, forging, spray fusing or spraying.C in steps: cover certain thickness high rigidity, high abrasion metal again outside the rough member profile after above-mentioned steps, and process, make it meet the external dimensions of concrete part.
The invention has the beneficial effects as follows, shock-resistant member of the present invention, and the member of making according to the method for the invention, used material hardness can be very high, and as normal temperature hardness number HRC＞60, its wearability is fine; Member allows crackle and exists, and crackle is difficult for expansion; Manufacturing process is simple.
Description of drawings
Fig. 1 is the one embodiment of the invention schematic diagram.
Fig. 2 is the another embodiment of the present invention schematic diagram.
The specific embodiment
Shock-resistant member, its manufacture method is, at first with certain thickness and toughness preferably steel plate produce rough profile according to part shape, should be divided into a plurality of spaces polyhedron grid by rough profile by welding manner or other modes with the steel plate of certain thickness good toughness again, become skeleton.Full high rigidity, high abrasion metal will be filled in the described polyhedron grid, and form metallurgical binding between the steel plate of space lattice, at last certain thickness high rigidity, high abrasion metal are filled in the rough profile outside of parts, and carry out external process, make its size reach the part requirement.
Certainly, also can directly utilize suitable profile shapes as skeleton.
Another kind of embodiment is to form skeleton by metal bar, and do not need to carry out space segmentation formation grid with sheet material.
Embodiment as shown in Figure 1, is used for the hammer body of single Kun disintegrating machine of iron and steel metallurgy enterprise sintering deposit fragmentation more specifically.Earlier according to the shape of hammer body, be welded into the rough profile of hammer body with the thick A3 steel steel plate of 15mm, make described profile be split into a plurality of little prisms or pyramid-shaped grid 2 with the thick A3 steel steel plate of 15mm by welding in the profile, formation skeleton 1; Will grid fill high rigidity, high abrasion metal with the built-up welding mode in 2, again according to profile built-up welding 1～2 floor height hardness, high abrasion metal outside grid of hammer body; To sharp processing, make it to meet the dimensional requirement of hammer body.
Described high rigidity, high abrasion metal ingredient are: C:0.4～6.5%, Si:0.3～2.5%, Cr:6～35%, Mn:0.3～2.5%, Mo:0～2.0%, V:0～2.5%, Nb:0-1.5%, Ni:0～2.8%, W:0～2.5%, S:0～0.40%, Ti:0-1.0%, Cu:0～0.5%, Al:0～0.6%, Co:0～2.5%, P:0～0.08%, O:0～0.08%, N:0～0.08%, all the other are Fe.
Its normal temperature hardness number is HRC58～65, and high temperature abrasion resistance is fine.During built-up welding, interlayer temperature should keep about 600 ℃, to reduce the cold crack of overlay cladding.
As shown in Figure 2, another embodiment is the sintering material scraping plate.The sintering material scraping plate is highly less cuboid, during manufacturing, earlier weld out appearance profile with the thick A3 steel plate of 20mm, with the thick A3 steel plate of 15mm it is divided into many little cuboid grid 7 in the profile, in the cuboid grid, fill full high rigidity, high abrasion resisting material, according to the dimensional requirement of sintered plate profile is processed again by the mode of built-up welding.Described high rigidity, high abrasion metal ingredient are: C:0.4～6.5%, Si:0.3～2.5%, Cr:6～35%, Mn:0.3～2.5%, Mo:0～2.0%, V:0～2.5%, Nb:0-1.5%, Ni:0～2.8%, W:0～2.5%, S:0～0.40%, Ti:0-1.0%, Cu:0～0.5%, Al:0～0.6%, Co:0～2.5%, P:0～0.08%, O:0～0.08%, N:0～0.08%, all the other are Fe.
