Definitions
- the present Invention Patent application refers to a grinding and beveling machine exhibiting remarkable advantages and innovations as opposed to those presently used with equal or similar purposes.
- This machine has been designed based on these requirements and more particularly for these strained materials.
- the grinding and beveling machine object of the present invention, ties up the material for continuous transport between two belts because it has to remove much more material and in this case even harder, whereas the present machines do not tie up the material, instead they only are transporting the material on a belt or band.
- the proposed machine at its first stage centers the material used since its sides become quite differently strained from the remaining machines which do not mechanically center the material, instead they only guide the material using steel side guides.
- the new machine both at first and at a second stage centers the workpiece and guides are not used at all because workpieces are held well tied-up.
- Tne present invention's machine at the second stage centers and squares the workpiece based on the two faces already ground and performs this operation piecemeal.
- the other machines do not either center nor square, the workpiece is only guided quite differently from the new machine which squares piecemeal whereas the prior art machines guide the workpiece and push themselves against, so the workpieces are not duly squared.
- the present invention 's machine ties up the material and works it piecemeal, centers it also piecemeal and at the second atage centers and squares it piecemeal and all that is achieved in a continuous cycle whereas the conventional machines, even also working in a continuous cycle, do not either tie-up, square, center and not even run piecemeal operations.
- a grinding and beveling machine as being manufactured for grinding and beveling ceramic materials such as stone, granite and marbles, its function to be the grinding of both sides of the material, by leaving them to the required dimension whet her the workpiece is squared or rectangular.
- the machine is manufacturated on a wide flanged double-T-shaped structure -1- assisted by 15 mm planes at its upper side for machining and grinding, this surface remaining perfectly flat and all its holes parallel at both sides to fit heads.
- Bedframe width and length remain contingent to the requirements specified in the material to be worked.
- the bedframe -1- will be more or less wide; said bedframe will lengthwardly be subordinated to the material depending on its hardness and quality and production specifications. The more requirements in all these specifications, the more number of heads shall be incorporated to the bedframe -1-; therefore the latter shall always be longer in these cases.
- Said machine comprises two parts.
- the first is the one designed for guiding and beveling two sides of the workpiece, being the workpiece collected at the beginning of the machine and centered by a mechanical and electronic mechanism which function is to locate all the workpieces and always the two sides which are to be ground and beveled.
- This work locator -5- will perform two centerings, at the two ends of the workpiece, leaving it squared for introduction into the machine and they will remain perfectly squared and dimensioned so that the right and left-hand grinders -8- tear off the same quantity of material.
- a workpiece rotator-12- will be incorporated with a 90Q degrees rotation or any other required degrees if the workpieces are not squared, the two earlier ground sides remain at a front position in the access for the second stage.
- This machine's second stage consists in the grinding and beveling of the two remaining sides of the workpiece, with the difference that the machine's work locator -13- must perform the same function shown for the first stage -5- as regards to centering the two remaining sides of the workpiece.
- this same work locator -13- will perform a longitudinal motion and bear the workpiece against the rear ground side and on the workpiece's quadrature adjusting slippers which in turn will be operated as a support for inserting the workpiece inside the machine, until being fully fixed and tied up for transport in the grinding operation.
- This work locator-13- is essential for machine operations since through side centerings, aligning the quadrature slippers with the workpiece, and introduction inside the machine, a perfect quadrature will be achieved.
- the motions of this work locator -13- are driven by electronic and pneumatic mechanism, all them interlocked for their perfect operation.
- the slipper adjustment for the quadrature fitting is manufactured on a grooved shaft so that any possible variation errors could be avoided by making a rotation to provide support and abutting to the workpieces.
- Said work locators -5- and -13- will perform its operation by acting on a single piece at each motion.
- the grinders-8- and the bevelers -9- are fitted by units on a fixed adjusting base -6-, both the grinder - 8- and the beveler -9-, the latter however having a vertically 45° degrees base for t he beveling operation whereas in turn on these bases are fitted the linear slides -7- for adjustment and being manufactured with anticorrosive and oil-bathed materials for their protection.
- this slide -7- comprises two aluminium plates constructed with 4.5 to 5% magnesium to avoid any corrosion and among them an adjustable solid body is formed using two dovetails at the end of each plate.
- the bottom or base plate being male and the upper and motor base being the female. They are shifted by means of a stainless steel spindle and bronze nut to avoid any clogging of this mechanism.
- This slide -7- is protected with a lower and internal tray while concurrently said slide -7- is in turn located inwardly to have it oil-bathed while an external and upper tray prevents any possible water splashes on this mechanism, thereby a perfect operation is thus obtained.
- Switchboards are manufactured as per any standards specified at the time and to the requirements of the function of said machine as regards to safety, being all them located off reach of any wet environment. both its power and driving -11- being all them well protected with the electrical components specified at the time by the Ministry of Industry, for selling both in the domestic market and abroad.
- This machine is designed to individually switch off each grinder-8- or beveler-9- to the full, just to put up the utmost safety in its handling or eventual failure.
- the machine is manufactured with a water circuit -10- for cooling the diamonds and stones, all that duly protected with an individual pressure for each grinder -8- and beveler -9- with its individual switching off and cancellation.
