Description
Technical field
The utility model belongs to emery wheel field, is specifically related to a kind of sandwich type mill roller abrasive wheel of processing hot roll.
Background technology
Hot roll is parts of hot roll grinding machine, be divided into two kinds of working roll and backing rolls, be mainly used in hot rolling cogging and shaped steel shaping roll, hot roll is difficult grind material, when processing hot roll, (common roll dressing surplus is below 0.8mm greatly for grinding allowance, hot roll is 1 to 3mm, when grinding, the amount of feeding is that 0.2mm to 0.3mm is (when common roll dressing, the amount of feeding is no more than 0.05mm), the quality requirement of grinding is higher, adopts common mill roller abrasive wheel grinding heat roll to be difficult to reach processing request.
Utility model content
The purpose of this utility model is to solve prior art and processes the defect that the emery wheel of hot roll cannot be taken into account on grinding efficiency and grinding accuracy, a kind of sandwich type mill roller abrasive wheel is provided, its grinding capacity is strong, grinding efficiency is high, grinding accuracy high (grinding burn and grinding crack do not occur), with pore and radiating groove.
The utility model is achieved by the following technical solution:
Be a kind of sandwich type mill roller abrasive wheel, it is characterized in that circular emery wheel is outwards followed successively by the sandwich portion of centre bore, ring-type and the grinding part of ring-type by center, sandwich portion is fine granularity abrasive material portion, and granularity is 70-90 order; Grinding part is coarseness abrasive material portion, granularity is 30-54 order, in coarseness abrasive material portion, be distributed with micro-pore, the aperture of micro-pore is 0.4-0.6mm, and two side end faces of coarseness abrasive material portion are provided with chip removal groove, and chip removal groove tilts 10 °-25 °, being radial is uniformly distributed, in described centre bore, be set with centre bore cover, described center borehole jack and centre bore are interference fit, and the outside of center borehole jack is provided with outwardly projection.
As a preferred version of the present utility model: the cross section of described projection is trapezoidal, protruding circumference in equal parts, is evenly distributed on the outside of centre bore great waves.
Center of the present utility model borehole jack, can improve the quality of fit of emery wheel aperture and grinding machine spindle, and its external diameter is slightly larger than the internal diameter of emery wheel centre bore, is interference fit between the two, and for ensureing to be connected firmly, borehole jack outside in center is provided with projection.
Sandwich of the present utility model portion is fine granularity abrasive material portion, and because this wheel strength requires highly, working position is again with pore, and its active line speed is 50 to 65m/s, and sandwich portion adopts fine granularity abrasive material can play humidification.
Grinding part of the present utility model is coarseness abrasive material portion, in coarseness abrasive material portion, is distributed with micro-pore, and grinding burn and grinding crack do not occur.
Two side end faces of coarseness abrasive material portion are provided with chip removal groove, play chip removal and thermolysis.
The advantage that the utlity model has that penetraction depth is large, production efficiency is high, be difficult for burn workpiece, grinding accuracy is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is section structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of the utility model center borehole jack.
As shown in FIG.: 1. coarseness abrasive material portion; 2. fine granularity abrasive material portion; 3. center borehole jack; 4. centre bore; 5. chip removal groove; 6. projection.
Detailed description of the invention
As Fig. 1, shown in Fig. 2: the thickness of emery wheel is 75 to 150 millimeters, sandwich portion is fine granularity abrasive material portion 2, the granularity of particle is 70 to 90 orders, grinding part is coarseness abrasive material portion 1, the granularity of particle is 30 to 54 orders, in coarseness abrasive material portion 1, be distributed with multiple micro-pores, the both sides end face of coarseness abrasive material portion 1 is provided with chip removal groove 4, chip removal groove tilts 18 °, be on the radial end face that is evenly distributed on coarseness abrasive material portion 1, center borehole jack 3 is installed in centre bore 4, the effect of center borehole jack is concentricity and the quality of fit that ensures emery wheel and grinding machine spindle, center borehole jack 3 is interference fit with centre bore 4, in order to ensure to be connected firmly, the outside of center borehole jack 3 is provided with circumference in equal parts, equally distributed multiple protruding 6, the cross section of projection 6 is trapezoidal.
