Abstract
A large-diameter consolidated grinding wheel is composed of a disk-shaped metal base body and a sector grinding block surrounding the external ring of said base body. The base body is a precision-cast aluminum base body, an adjusting hole is formed in the plane of the base body, the belly of the base body can be hollowed or thinned, and a circle of U-shaped groove is formed in the excircle of the base body; 12 ~ 48 fan-shaped grinding blocks, its inner arc position embedding base member U-shaped inslot, the junction has the metal round pin, and all joint faces scribble high strength and glue, leave 2 ~ 8 mm's clearance between the adjacent grinding block. The utility model is used for grinding medium and large workpieces in machining, the metal matrix has high strength and light weight, can be repeatedly used, and saves materials; the fan-shaped grinding block is easy to manufacture, the product quality can be ensured, large investment is not needed in production, and the cost is low; the clearance between the grinding blocks plays the roles of heat dissipation and chip removal, and the grinding effect is further improved.
Description
Technical field
The utility model relates to a kind of bonded abrasive tool, the particularly diameter large-diameter concretion abrasive wheel greater than 900mm.
Background technology
As everyone knows, the diameter of emery wheel is big more, and it is poor more that its moulding feeds intake, spreads out the uniformity of material, and the bad meeting of uniformity directly causes the imbalance of emery wheel, influences its revolving strength and ground effect, causes waste product easily.Diameter is greater than the concretion abrasive wheel of 900mm, and promptly so-called large-diameter concretion abrasive wheel is monolithic construction for a long time, exist inevitably to feed intake, spread out the material lack of homogeneity and internal injury easily takes place when burning till, give birth to defectives such as burnings, crackle, thereby product quality be cannot say for sure to demonstrate,prove.And need great tonnage press, large-scale tooling device and big volume stove, kiln furnitures in producing, cause equipment investment big, the production cost height.
The utility model content
The purpose of this utility model be to provide a kind of making easily, investment is little, cost is low, and the quality large-diameter concretion abrasive wheel that can guarantee, this emery wheel can also further improve ground effect.
The technical solution of the utility model is: the improvements of large-diameter concretion abrasive wheel are to be bonded to one by discoid metallic matrix and the fan-shaped grinding block that is centered around the metallic matrix outer ring.
Further scheme is: described metallic matrix is smart cast aluminium matrix; There is a circle U-lag at the cylindrical place of described metallic matrix, and the interior circular arc position of described fan-shaped grinding block embeds in the U-lag, and the junction scribbles high strength glue; There is metallic pin described grinding block and metallic matrix junction, and the metallic pin surface scribbles high strength glue; 12～48 of described fan-shaped grinding blocks leave the gap of 2～8mm between the adjacent grinding block; Described metallic matrix belly is emptied or attenuate, and is provided with reinforcement; The plane of described metallic matrix is provided with adjusts the hole.
Adopt above technical scheme, big emery wheel is formed with the high strength glue bond by metallic matrix and fan-shaped grinding block, and there is U-lag the junction, adds metallic pin, and it is firm to connect; The particularly smart cast aluminium matrix of metallic matrix, the intensity height, in light weight, also reusable, save material; Adjustment hole on the matrix can be adjusted the balance of emery wheel easily.Fan-shaped grinding block is made easily owing to size, the whole emery wheel of volume ratio are much smaller, can avoid all drawbacks in the whole emery wheel manufacturing, the assurance product quality, and do not need big input, reduce production costs.Gapped between the particularly fan-shaped grinding block, play heat radiation, chip removal effect, make ground effect better.
Description of drawings
Fig. 1 is the utility model structural profile schematic diagram;
Fig. 2 is an A-A place profile among Fig. 1.
The specific embodiment
Consult accompanying drawing, the external diameter of discoid smart cast aluminium matrix 1 is 1400mm, thickness is 60mm, diameter of bore is 305mm, there is the U-lag of wide 50mm, dark 5mm at matrix cylindrical position, the circumference of upper edge, matrix plane φ 1300mm is provided with the adjustment hole 2 of 24 uniform φ 10mm, matrix belly attenuate, and leave reinforcement.24 fan-shaped grinding blocks 3 that are centered around the matrix outer ring embed in the U-lag of matrix, metallic pin 4 is inserted in the joint portion, and the faying face of metallic pin, fan-shaped mill pin block and matrix all scribbles phenolic resins high strength glue, each exterior arc surface that grinds pin block all is positioned on the circumference of φ 1600mm, and the gap of 4mm is arranged between the adjacent grinding block.
