Description

Use the method for saw blade machine table panel square opening

Technical field

The present invention relates to a kind of method, belong to special-shaped stone goods manufacture field by square opening on the saw blade processing stone material deck plate.

Background technology

Along with science and technology development reaches and people's advocating the Nature, stone product has obtained using widely at building decorating industry with its natural magnificent color and physical property, become the trend of building decorating industry development, all embody the function and the aesthetic effect of lithotome goods everywhere, the stone material deck plate especially with its extremely strong resistant, acidproofly, corrosion-resistant, wear-resisting undermine good self-cleaning property, add the quality noble quality, elegant appearance, demand enlarges year by year.The design feature of deck plate is that peripheral curve, centre hollow out, and the key problem of processing is exactly the processing of outer edge shape line.For the roughing of larger-size peripheral curve or hollow space, finger cutter commonly used at present or saw blade excision forming.Adopt finger cutter processing peripheral curve or dig endoporus, low to the functions of the equipments requirement, only need two-axle interlocking, the endoporus joint-cutting is neat, and it is little that following process is removed surplus, but the speed of mainshaft is higher, and tool wear is bigger, and efficient is low, is not suitable for producing in batches.When saw blade cut peripheral curve or digs endoporus, because the saw blade linear velocity is big, clearance significantly promoted, and cutter life improves.But saw blade is when the processing square opening, because the influence of special-shaped stone goods Compositions of metal-working machines common diamond disc power transmission shaft ring flange and saw blade profile, square opening sideline end the saw kerf degree of depth inevitably can occur and become the saw blade circular shape to distribute, cut incomplete problem, follow-up molding cutter adds that to remove surplus man-hour bigger, even causes bursting apart of deck plate corner.

Summary of the invention

The present invention is directed to the existing deficiency that exists by special-shaped stone goods Compositions of metal-working machines machine table panel square opening technology, provide a kind of stable performance, reliable quality to use the method for saw blade machine table panel square opening.

The method of application saw blade machine table panel square opening of the present invention may further comprise the steps:

(1) design and produce a kind of annular saw device, this annular saw device comprises handle of a knife, casing, transmission mechanism and saw blade, and transmission mechanism is installed in the casing, and the power shaft of transmission mechanism is connected with handle of a knife, and saw blade is installed on the output shaft of transmission mechanism by ring flange; During use, casing is positioned on the shell of electrocardio main shaft in the processing of stone by alignment pin, handle of a knife is installed in the taper hole of electrocardio main shaft in the processing of stone, by the frictional force clamping between handle of a knife and electric main shaft wall, handle of a knife drives saw blade by the transmission mechanism in the casing and rotates at a high speed, finishes the square opening processing of deck plate;

(2) preprocessing of deck plate square opening, be installed in the taper hole with special-shaped stone goods Compositions of metal-working machines electricity main shaft cutter calibration function and that possess at least four radical control axles by handle of a knife the annular saw device of step (1) made and clamping, finish the processing of the prefabricated square opening of deck plate, and reserve allowance;

(3) processing eventually of deck plate square opening, 180 ° of the special-shaped stone goods Compositions of metal-working machines electricity main axis rotation that step (2) is adopted, make the outer surface of saw blade be positioned at Working position, and the center of circle of saw blade is placed the centre position of deck plate thickness, finish the processing of reservation allowance of the square opening of deck plate, make the deck plate square opening meet the requirements of the square opening size.

The allowance of reserving in the above-mentioned steps (2) determines according to the radius of common diamond disc and the relative position of saw blade and deck plate, and establishing the saw blade center is h to the distance of deck plate upper surface ₁, be h to the distance of deck plate lower surface ₂, the radius of diamond disc is R, then reserves allowance r to be

The present invention cooperates common diamond disc to finish processing to the deck plate square opening by the annular saw device that designs and produces, otch is smooth, and follow-up yarn when being shaped institute's allowance that stays less, whole process, operation is simple, reasonable and working (machining) efficiency is high, the desk product quality height of being produced, the place, sideline is smooth, has the advantage that common process technology can't be finished.

The specific embodiment

The method of application saw blade machine table panel square opening of the present invention at first is to design and produce a kind of annular saw device, and this annular saw device comprises handle of a knife 1, casing, transmission mechanism and saw blade 6 as shown in Figure 1.Handle of a knife 1 is the general SK type of a machining center handle of a knife, can directly be installed in the taper hole of electrocardio main shaft in the processing of stone.Casing is positioned on the electric main shaft shell by alignment pin, makes itself and electric main shaft shell relative fixed.Transmission mechanism is installed in the casing, and power transmission shaft 2 is power shafts of this transmission mechanism, and power transmission shaft 5 is output shafts of this transmission mechanism, and bevel gear 3 is installed on the power transmission shaft 2, and bevel gear 4 is installed on the power transmission shaft 5, bevel gear 3 and bevel gear 4 engagements.The end of power transmission shaft 5 is equipped with saw blade 6 by ring flange 7, and saw blade 6 contains the ring flange of installing 7 fully, makes its working face in a plane.

Add man-hour at the square opening that carries out deck plate 8, after reasonably putting and placing workpiece, at first as shown in Figure 2, with the annular saw device of making 10 be installed in have cutter calibration function and electric main shaft that possess at least four radical control axles on, along the track feed that the physical dimension 11 of prefabricated square opening requires, finish the preprocessing of deck plate square opening.Leave certain allowance between the physical dimension 11 of prefabricated square opening and the deck plate square opening physical dimension 9.The allowance of reserving determines according to the radius of common diamond disc and the relative position of saw blade and deck plate, and establishing the saw blade center is h to the distance of deck plate upper surface ₁, be h to the distance of deck plate lower surface ₂, the radius of diamond disc is R, then reserves allowance r to be

$\sqrt{R^2-{\mathrm{<figure-callout\; id="1"\; label="h"\; filenames="110504191152.png,110504191155.png"\; state="\{\{state\}\}">h</figure-callout>}}_1^2}-\sqrt{R^2-{\mathrm{<figure-callout\; id="2"\; label="h"\; filenames="110504191155.png"\; state="\{\{state\}\}">h</figure-callout>}}_2^2}.$

Then as shown in Figure 3, adjust machining center, with 180 ° of Compositions of metal-working machines electricity main axis rotation, so also Rotate 180 ° of the annular saw device 10 that the present invention designs and produces, make the outer surface of saw blade be positioned at Working position, and the center of circle of saw blade is placed the centre position of deck plate 8 thickness.The track feed that annular saw device 10 is required along deck plate square opening physical dimension 9, under the control of program, any three-shaft linkage of the X-Y-Z-C between centers by special-shaped stone goods Compositions of metal-working machines is finished the processing that the deck plate square opening is reserved allowance.
