Abstract
The utility model discloses a high-thickness bonded grinding wheel for infeed grinding, which is integrated by bonding a plurality of thin grinding wheels. Joint faces of the bonded position of the adjacent thin grinding wheels are inclined faces skewed to the axis of the grinding wheel. Number of the thin grinding wheels ranges from two to four, inclination angle Alpha of the inclined faces ranges from 1 degree to 5 degrees, and preferably the inclination angles of the inclined faces are equal. The high-thickness bonded grinding wheel is easy in fabrication and low in production cost, and is capable of guaranteeing uniformity of density, structure and harness. When used for infeed grinding upon workpieces, contact portion between the inclined-face joint and the workpieces axially continuously moves along with rotation of the grinding wheel, thereby guaranteeing all surfaces of the workpieces to be ground by effective grinding portions of the grinding wheel, resolving the problem that existing plain wheels after combination have poor grinding effect at the joint without secondary trimming and further increasing working efficiency and grinding effect.
Description
Technical field
The utility model 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.
The utility model content
The technical problems to be solved in the utility model 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.
The technical solution of the utility model 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 for the utility model, and the composition surface of adjacent thin emery wheel is the inclined-plane, 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 utility model 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.
