Abstract
The utility model provides a multi-layer uniformly-distributed diamond cold-pressing sintering sawblade which is provided with a tool bit that is formed by sintering powdery metallic bond and diamond, wherein the metallic bond is in layered arrangement as carcass with the number of layers being 2-12, the diamond is uniformly distributed on each layer and in column arrangement, and adjacent columns are in positive-location or dislocation arrangement. The diamond is uniformly distributed on the carcass in layered arrangement by columns, so that the multi-layer uniformly-distributed diamond cold-pressing sintering sawblade has the characteristics of high cutting efficiency and long service life.
Description
Technical field
The utility model relates to the cold pressing sintered diamond cutting tool, particularly relates to the manufacturing field of the cold-rolled sintered sawing of the uniform diamond of multilayer, mill, brill goods.
Background technology
Current cold pressing sintered diamond saw blade, grinding tool, drilling tool all are to adopt metal dust to add diamond to carry out batch mixing, pouring the punching block strickling into by the deal of its design exerts pressure with hydraulic press, metal dust and adamantine compound are combined with matrix by exerting pressure, the green compact of form diamond composition, put into the sintering furnace sintering of heating again, by the temperature that is provided with metal dust and adamantine compound and matrix are fused together, become diamond saw blade, grinding tool or drilling tool.This traditional production technology also is the technology that most so far diamond tool manufacturing enterprise adopts.No matter cold-rolled sintered saw blade is from the quantity of manufacturing enterprise, or position first of the output Dou Ju world.There is the big and small diamond tool manufacturing enterprise of nearly thousand tame scales in the whole nation, produces tens million of of various diamond saw blades per month, tens thousand of of the enterprise that has daily outputs, and few also more than thousand, a month output value reaches several hundred million units.Because conventional process techniques falls behind, and can not produce the high product of cutting efficiency.Along with, use the cost of labor of diamond tool to go up, it is more obvious to require have high efficiency cutting tool to reach the trend that reduces cost of labor.And produce diamond tool enterprise owing to the traditional production technique that adopts, and promptly metal dust adds the technology that diamond carries out mechanical mixture, can't avoid the defective of diamond distribution inequality, and it is excessive that diamond is heaped the part resistance, and cutting efficiency is low; The very few part of diamond consumes fast; Do not have diamond partly, can't cut.Such technology can't be produced the target of high efficiency diamond saw blade.Evidence, the diamond saw blade that uses conventional art to produce at present, doing section with Φ 114 is example.Price is cut the thick granite slab of 20mm in 20 yuan/sheet, granite hardness is 100 degree, with the continuous dried per minute average efficiency of cutting 40m of desk-top cutter.Most enterprises have only the efficient of 0.2 ~ 0.4m, and minority enterprise product quality is better, also can only reach the efficient of 0.5 ~ 0.7m, and the efficient that reaches 1.0m apart from the customer requirements per minute differs greatly, and this is long-time technical problem of wishing solution.
The utility model content
The purpose of this utility model provides the cold-rolled sintered saw blade of the uniform diamond of multilayer of a kind of cutting efficiency height, long service life.
The purpose of this utility model is achieved in that the cold-rolled sintered saw blade of the uniform diamond of a kind of multilayer, saw blade tip is formed by granulated metal bond and diamond sintering, metallic bond is provided with as the carcass layering, the number of plies is between 2～12 layers, diamond is distributed on each layer, and diamond is provided with by being listed as, and arranges or the dislocation arrangement for normotopia between adjacent column and the row.
Above-mentioned diamond is distributed on the carcass by craft or vacuum material distributing machine.
Compared with prior art, the utlity model has following characteristics and advantage:
1, inside and outside the caking of a saw blade, with diamond uniformly, the cloth of multilayer is on the metallic bond carcass, particularly diamond is provided with by row, every row diamond is radial arrangement on circular saw blade, overcome the defective of conventional art, guarantee the diamond average force, stablize work done, realize high efficiency.
2, the uniform diamond saw blade of multilayer is according to uniform 2～12 layers of diamond of product needed when producing.Adopt modes such as craft, template, Compressed Gas or vacuum, (ZL200820061656.4) diamond concentration needed cloth to carry out sintering (not having pressure or pressure sintering) on the metallic bond carcass to form according to product as the inventor " vacuum material distributing machine ".
3, adopt the uniform diamond of multilayer to produce DC-Φ 114 saw blades for dry cutting that cold-rolled sintered saw blade new technology is produced, use desk-top cutter, the hard granite 30m of the isogonic that hits average efficiency, per minute reaches the high efficiency of 1.34m, than the batch mixing type saw blade efficient with same material is 0.78m, raises the efficiency 71.8%.This new technology has powerful vitality, and very high economic benefit and social benefit are arranged.
Description of drawings
Fig. 1 Fig. 2 is respectively the front view of this new type of continuous circular saw blade (dislocation is arranged and normotopia is arranged);
Fig. 3 Fig. 4 is respectively the front view of the tooth-like circular saw blade of this novel branch (dislocation is arranged and normotopia is arranged).
The specific embodiment
Fig. 1～4 illustrate, the cold-rolled sintered saw blade of the uniform diamond of multilayer, saw blade tip is formed by granulated metal bond and diamond sintering, metallic bond is provided with as the carcass layering, the number of plies is between 2～12 layers, diamond is distributed on each layer, and diamond is arranged or the dislocation arrangement for normotopia between adjacent column and the row by being listed as setting.Diamond is provided with by row on each layer of carcass and every row diamond is emitting shape substantially.Saw blade tip is divided into the tooth-like or continous way of branch.Carcass thickness is less than 9.6mm, and diameter is not more than 0.45m.Diamond is distributed on the carcass by craft or vacuum material distributing machine or other machinery.
With Fig. 3 is example, and the metallic bond (as iron powder, copper powder, glass putty, nickel powder, cobalt powder etc.) for preparing as carcass 1, is cold-pressed into sheet again, by uniform diamond distributing mode, be stratified and set between 2～12 layers, the number of plies is determined according to the saw blade size, uniform diamond 2 on each layer.The cold moudling punching block of more uniform good adamantine metal powder tailpiece being packed into is successively exerted pressure with hydraulic press, and metal powder tailpiece and matrix are integrated as the saw blade green compact, and the sintering furnace of packing into sinters diamond saw blade and goods into.
With these novel Φ 114 cold-rolled sintered saw blades of uniform diamond (this product) is example, carries out cutting test with the cold-rolled sintered saw blade of existing batch mixing type (contrast product), contrasts as follows:
The test data sheet of this product cutting blade:
Efficient: 1.28m 1.54m 1.24m
The test data sheet of contrast product cutting blade:
Efficient: 0.74m 0.73m 0.91m
Conclusion, under three groups of conditions of equivalent, the cutting efficiency of the existing cold-rolled sintered saw blade of batch mixing type is respectively 0.74m/ minute, 0.73m/ minute and 0.91m/ minute.And the cutting efficiency of the cold-rolled sintered saw blade of the uniform diamond of this novel multi-layer corresponds to: 1.28m/ minute, 1.54m/ minute and 1.24m/ minute.Cutting efficiency has improved 73%, 111%, 36% respectively.
