Abstract
The invention discloses a high-thickness consolidated grinding wheel for plunge grinding, which is formed by bonding a plurality of thin grinding wheels into a whole, wherein the joint surface of the bonding parts of the adjacent thin grinding wheels is an inclined surface inclined to the axis of the grinding wheel. The thin grinding wheels are 2-4, the inclination angle alpha of each inclined plane is 1-5 degrees, and preferably the inclination angles alpha of the inclined planes are equal. The invention has easy manufacture and low production cost, can ensure the uniformity of the density, the structure and the hardness of the grinding wheel, can ensure that all the surfaces of the workpiece have effective grinding parts of the grinding wheel to participate in grinding because the contact part of the inclined interface and the workpiece continuously axially moves along with the rotation of the grinding wheel when the grinding wheel is used for cutting-in and grinding the workpiece, solves the problem of poor grinding effect of the interface after the existing flat grinding wheel is combined, does not need secondary finishing, and further improves the working efficiency and the grinding effect.
Description
Technical field
The present invention relates to a kind of machined concretion abrasive wheel, especially for the large-thickness consolidated grinding wheel of incision mill.
Background technology
Along with the development of mechanical processing industry, the large-thickness consolidated grinding wheel that is used to cut the thickness 〉=400mm of mill is used increasingly extensive, is subjected to the favor of more and more producers.But the thickness of emery wheel is high more, and manufacture difficulty and cost are also big more.The one, need the large-tonnage press, equipment investment is big; The 2nd, critical technological point is many, because emery wheel lacks gradually in the transmission of moulding pressing process pressure, position, the upper, middle and lower hardness and the density of high thickness emery wheel are difficult to be consistent, and cause can causing when crush grinding workpiece different parts grinding degree varies to cause, and do not reach desirable grinding.Usually feed intake several times when moulding feeds intake and smash pressure, in the hope of the hardness unanimity, but tend to cause the irregular of density, tissue, wheel balance is relatively poor.In addition, defectives such as aliquation, crackle, distortion also very easily take place in high thickness emery wheel in drying, sintering process, have a strong impact on product quality and economic benefit.At present, most producers carry out grinding with the straight-type wheel clamping of two or two above same sizes or the high thickness emery wheel of formation that bonds together, but because just radially feed of incision mill, axially not feed, thereby the joint of multi-disc emery wheel will be left a trace at a certain position of workpiece, also need the secondary finishing, influence operating efficiency and workpiece quality.
Summary of the invention
The technical problem to be solved in the present invention is the existing weak point of high thickness emery wheel that overcomes the existing high thickness emery wheel of monoblock type and be made of the multi-disc straight-type wheel, provide a kind of making easily, cost is low, the emery wheel quality is good, can increase work efficiency when being used to cut mill and the large-thickness consolidated grinding wheel of ground effect.
Technical scheme of the present invention is: thin emery wheel is bonding is integral by multi-disc for large-thickness consolidated grinding wheel, and its improvements are that the composition surface of adjacent thin emery wheel abutting edge is the inclined-plane that favours the emery wheel axis.
Further scheme is: described thin emery wheel is 2～4; The inclined angle alpha on described inclined-plane=1 °～5 °, inclined angle alpha are meant the angle between the vertical plane of this inclined-plane and emery wheel axis; The inclined angle alpha on described each inclined-plane equates.
According to above technical scheme, thin emery wheel is bonding is integral by multi-disc in the present invention, and the composition surface of adjacent thin emery wheel is the inclined-plane, has both solved the problem that the high thickness emery wheel making of monoblock type difficulty is big, cost of investment is high, can guarantee density, the tissue of emery wheel, the uniformity of hardness, improve the quality of products; Make the present invention again when making crush grinding, although do not have axially-movable between emery wheel and workpiece, but rotation along with emery wheel, inclined-plane interface and workpiece contact site constantly move axially, can not stay the ring-type vestige at surface of the work, all surface that is to say workpiece can both have effective grinding position of emery wheel to participate in grinding, and this has just solved the problem of the interface ground effect difference after the straight-type wheel combination, no longer need the secondary finishing, and then increase work efficiency and ground effect.The inclined angle alpha on described inclined-plane is elected 1 °～5 ° as, and preferably each inclined-plane inclined angle alpha equates, can further guarantee product quality like this, simplifies manufacture craft, reduces cost.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is another structural representation of the present invention;
The specific embodiment
Further specify the present invention below by embodiment.
Example one: see Fig. 1, large-thickness consolidated grinding wheel is 1-600 * 500 * 305WA/F60J7V-35m/s, thickness T=500mm, combine after bonding by thin emery wheel 1,2 and 3, thin emery wheel 1 and 2 and the composition surface of thin emery wheel 2 and 3 be respectively inclined-plane 4 and 5, inclined-plane 4 and 5 and the vertical plane of emery wheel axis between angle α be 2 °, inclined-plane 4 and 5 intersects, thin emery wheel 1 is identical with 3 specifications.
Example two: see Fig. 2, large-thickness consolidated grinding wheel is 1-500 * 420 * 305A/F46K7V-35m/s, thickness T=420mm, combine after bonding by thin emery wheel 6,7,8, thin emery wheel 6 and 7 and the composition surface of thin emery wheel 7 and 8 be respectively inclined- plane 9 and 10, inclined- plane 9 and 10 and the vertical plane of emery wheel axis between angle α be 4 °, inclined- plane 9 and 10 parallels, thin emery wheel 6 is identical with 8 specifications.
