Description
Technical field
The present invention relates to a kind of emery wheel, relating in particular to diameter is the improvement of the major diameter emery wheel of 300-500mm.The invention still further relates to the new application of this major diameter emery wheel aspect grinding.
Background technology
In casting field, come steel such as steel bar, steel pipe are ground with bar surface finish emery wheel and waste grinding abrasive disk usually.This type of emery wheel is thicker usually.For example, U.S. electric Worktools Inc. (KY) size of this type of emery wheel of Sheng Chaning has the diameter of 14-30 inch (about 355.6-762mm) usually for United StatesElectrical Tool CO., FT.MITSHELL, and its thickness is about 3 inches (76.2mm).Fox's mould Co., Ltd (FOX GRINDERS, INC., HELEA, AL) thickness of the grinding wheel of Sheng Chaning is usually at 1-3 inch (about 25.4-76.2mm).But, this grinding special grinding wheel needs specialized apparatus manufacturing, thereby its cost is very high, thereby price is very expensive.
Also have a kind of slim emery wheel in field of machining, wherein a kind of stock size is the emery wheel of 400 * 3 * 32mm, and the emery wheel of this specification is commonly used to cut steel such as steel bar, steel pipe.In general, the emery wheel of this specification can not be used for grinding, because this can produce the reason of secure context, such as, the emery wheel of this specification is easy to generate explosion in process of lapping.But, some Chinese users emery wheel of createing a kind of usefulness 400 * 3 * 32mm specification grinds the method for steel tube surface oxide layer.Specific practice is as follows: the slim emery wheel of several pieces 400mm diameters is stacked formation emery wheel group, and the quantity of emery wheel depends on the central axis of machine, is generally 5 to 8, then, the emery wheel group that stacks is installed on the improved machine.Sometimes,, the machine that several are equipped with above-mentioned emery wheel group is installed respectively, grinds simultaneously at the diverse location place of the steel pipe that is ground in order to improve treatment effeciency.This Ginding process is schematically illustrated in Fig. 1.
Grind the emery wheel of steel pipe with traditional being used for and compare, the emery wheel of multi-disc 400 * 3 * 32mm is stacked up grind and greatly to reduce cost.But because slim emery wheel generally includes one deck reinforcement material layer at least, when the slim emery wheel of multi-disc was superimposed, the armature bed of material can take certain grinding size.Therefore, under measure-alike condition, because the existence of the armature bed of material, the effective grinding size of the slim emery wheel of multi-disc of stack will reduce, thereby reduce than traditional special-purpose grinding wheel grinding efficiency.And, compare with single sheet of thin molding sand wheel, the slim emery wheel of multi-disc is superimposed can improves security, but its burst rate is still than higher.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of new emery wheel design, this emery wheel is used for grinding, and it has low burst rate, and cost is lower.
Another object of the present invention provides a kind of manufacture method of emery wheel.
A kind of emery wheel according to the present invention comprises the grinding layer with abrasive material and binding agent, and the described abrasive material in the described grinding layer comprises the garnet of 5%-100% volume, and wherein, the diameter of this emery wheel is in the scope of 300-500mm, and thickness is in the scope of 4-30mm.
Emery wheel manufacture method of the present invention is as follows: the big press of this method utilization is exerted pressure, and wherein, institute's applied pressure is more than 3 times of prior art press pressure, thereby makes the emery wheel of producing have the interior thickness of scope of 4-30mm.
Description of drawings
Fig. 1 shows in the prior art slim emery wheel with 400 * 3 * 32mm and superposes and grind bar;
Fig. 2 shows the comparison of the slim emery wheel of emery wheel of the present invention and prior art, and wherein as can be seen, the thickness of emery wheel of the present invention obviously increases than the slim emery wheel of prior art;
Fig. 3 shows the generalized section according to the emery wheel of first embodiment of the invention;
Fig. 4 shows the generalized section according to the emery wheel of second embodiment of the invention.
The specific embodiment
Fig. 3 shows the cross-section structure according to the emery wheel of first embodiment of the invention.Grinding layer in the emery wheel 1 has been divided into the first grinding layer 10-1 and the second grinding layer 10-2, and emery wheel is also particularly including the fiber mesh cloth 20 between first grinding layer and second grinding layer.Grinding layer comprises abrasive material, binding agent and suitable additive (for example active or inactive packing material), can comprise any routine or unconventional grinding-material in the abrasive material in the grinding layer of emery wheel, such as garnet, alumina (for example brown corundum) and carborundum etc., or the combination of above grinding-material.Wherein, garnet content is more than 5%.Especially, in the present invention, garnet content can reach 100%.Need to prove that also two layer web cloth 20 can be set in grinding layer inside, correspondingly grinding layer will be divided into three layers.
In the emery wheel of second embodiment shown in Figure 4, on two surfaces two layer web cloth 20-1 and 20-2 are set respectively up and down at this grinding layer 10.This grinding layer comprises abrasive material, binding agent and suitable additive equally, and abrasive material comprises the garnet of 5%-100% volume.
The manufacturing process of emery wheel generally includes following steps: at first, to raw material be configured, batch mixing and storage, be pressed then, last, after the compression moulding of greensand wheel, it is carried out baking curing.In the prior art, in pressing process, because the restriction of press, for the major diameter emery wheel of 300-500mm diameter, its thickness can only be below 4mm usually.And in the present invention, adopting the big press step that is pressed, its applied pressure is more than 3 times of prior art press, thereby the thickness of the emery wheel of making can increase greatly.
According to major diameter emery wheel of the present invention, its diameter is 300-500mm, and thickness is 4-30mm.The diameter of this emery wheel preferably is 400mm.The thickness of emery wheel preferably is 6-10mm, more preferably is 8mm.
Compare with the emery wheel of 400 * 3 * 32mm of the prior art, be used for bar as if emery wheel of the present invention is stacked up and grind, its cost is lower.Table 1 is an example with typical 400 * 8 * 32mm emery wheel of the present invention, compares with the emery wheel of 400 * 3 * 32mm.
Table 1
| Size (mm) | The sheet number | Expense (RMB) |
| 400×3×32 | 5 | 40 |
| 400×8×32 | 2 | 30 |
| 400×3×32 | 8 | 64 |
| 400×8×32 | 3 | 45 |
As can be seen from the above table, when one timing of required emery wheel thickness, the thickness of monolithic emery wheel is big more, and then required grinding wheel number is just few.Especially, because the thickness maximum of emery wheel of the present invention can reach 30mm, therefore, in some cases, only need a slice emery wheel to grind, and the multi-disc emery wheel need not be superimposed.In addition, because the grinding wheel number reduces, the required armature bed of material also reduces.Thus, the cost of emery wheel descends.And required thickness is big more, and the cost of being saved is many more.In addition, because the quantity of the armature bed of material reduces, can add more abrasive material, thereby grinding performance is improved.
In addition, compare with 400 * 3 * 32mm emery wheel of prior art, if emery wheel stack of the present invention is used to grind bar, the burst rate of emery wheel will significantly reduce.
More than specific embodiments of the invention are described, but foregoing description only is to help the understanding of the present invention, protection scope of the present invention is not had any qualification effect.Protection scope of the present invention is limited by appended claims.
