MÁQUINA DE BROCAR EM PEDRA BRUTA OU POLIDA PARA OBTENÇÃO DE  GROSS OR POLISHED STONE DRILLING MACHINE FOR
CUBAS DE PIAS  SINK TUBES
Introdução Introduction
[0001 ] Refere-se o presente pedido de patente de Invenção de uma MÁQUINA DE BROCAR EM PEDRA BRUTA OU POLIDA PARA OBTENÇÃO DE CUBAS DE PIAS, especialmente de uma máquina com pelo menos um cabeçote com broca semi-esférica de quatro raios de corte que originam quatro cubas no mesmo formato e um tampo convexo originados de um bloco de pedra maciça inserida na plataforma pivotante basal de giro inverso ao da referida broca.  This patent application relates to a RAW or POLISHED STONE DRILLING MACHINE, especially a machine with at least one four-spoke semi-spherical drill head that they yield four vats in the same shape and a convex top originated from a block of solid stone inserted into the pivoting basal platform of reverse rotation to that of the drill.
Campo de aplicação Application field
[0002] O campo de aplicação da invenção ora pleiteada é o do segmento de equipamentos do ramo de marmoraria.  [0002] The field of application of the present invention is that of the equipment segment of the marble industry.
Estado da técnica State of the art
[0003] Atualmente, a obtenção de cubas de mármore, granito e outras pedras é feita a partir de um bloco de pedra prismático seja ele polido ou bruto. No caso da conformação de uma cuba de formato semi-esférico é necessário desbastar o miolo do bloco até que o mesmo alcance tal formato. Nesse caso, um bloco maciço dará origem a apenas uma cuba sendo que todo o material desbastado será perdido. Geralmente, a ferramenta utilizada é uma policorte de bancada devidamente manuseada por um operário de grande habilidade em marmoraria.  [0003] Nowadays, marble, granite and other stone vats are obtained from a prismatic stone block, whether polished or rough. In the case of forming a semi-spherical shaped bowl it is necessary to roughen the core of the block until it reaches that shape. In this case, a massive block will give rise to only one bowl and all the rough material will be lost. Generally, the tool used is a countertop copier properly handled by a skilled marbling worker.
[0004] Nesse processo artesanal, o operário faz o desbaste circular no centro da pedra bruta (maciça no formato quadrado ou retangular), a fim de retirar o material com a escavação de ferramentas como talhadeiras e serras elétricas / policorte gerando estilhaços, conformando assim a parte côncava da cuba semi-esférica. A remoção desse material não é aproveitável, ou seja, é desperdiçado sendo equivalente a área desbastada. Para uma melhor elucidação do processo de conformação manual da cuba, o operário faz a marcação da circunferência e com o auxílio de ferramentas perfaz rasgos em cruz no círculo demarcado, de modo que após esses rasgos faz os desbastes retirando os estilhaços até que tome forma a parte côncava formatando a cuba. [0005] O atual estado da técnica antecipa alguns documentos de patentes que versam sobre a matéria em apreço, como o PI9802633-0 intitulado "Dispositivo para Fabricação de Cuba para Pias e Lavatórios" - que prevê um equipamento, destinado a fabricar cubas para pias e lavatórios a partir de blocos de pedra, podendo ainda ser aproveitado para fabricar outros tipos de peças com acabamento interno em profundidade e externo; sendo o equipamento composto de peça móvel, peça giratória, carrinho de translação da mesa, gabarito/batente, trilho, base do dispositivo, rolamento, conjunto de acionamento, disco de corte diamantado, suporte para acabamento externo das peças, conjunto este que utilizado permitirá fabricação em linha industrial das cubas ou peças com polimento interno e externo. [0004] In this artisan process, the worker makes the roughing circular in the center of the rough stone (massive in square or rectangular format), in order to remove the material with the excavation of tools such as chisels and electric saws / polycut generating shrapnel, thus forming the concave part of the semi-spherical vat. The removal of this material is not usable, that is, it is wasted being equivalent to the thinned area. For a better clarification of the manual shaping process of the bowl, the worker makes the circumference marking and with the help of tools he makes cross tears in the demarcated circle, so that after these tears makes the thinning removing the shards until it takes shape. concave part shaping the vat. [0005] The current state of the art anticipates some patent documents dealing with the subject matter, such as PI9802633-0 entitled "Device for the Manufacture of Sinks and Sinks" - which provides equipment for making sinks for sinks. and washbasins from stone blocks, which can also be used to manufacture other types of pieces with deep internal and external finishing; being the equipment composed of moving part, swivel part, table translation trolley, jig / stop, rail, device base, bearing, drive assembly, diamond cutting disc, support for external finishing of parts, which set will allow industrial on-line manufacture of vats or parts with internal and external polishing.
[0006] O documento acima prevê uma mecanização na operação de desbaste da parte interna das cubas, no entanto todo o material desbastado é perdido, ao contrário do pedido ora pleiteado em que apenas uma pequena parte do material desbastado é desperdiçada. [0006] The above document provides for a mechanization in the roughing operation of the inner part of the vats, however all the roughed material is lost, unlike the request now claimed in which only a small part of the roughed material is wasted.
Objetivos da invenção Objectives of the invention
[0007] É objetivo da presente invenção, propor uma máquina que retire pelo menos quatro cubas de um bloco de pedra maciço ao invés de apenas uma cuba.  It is the object of the present invention to propose a machine that removes at least four vats from a block of solid stone rather than just one vat.
[0006] É objetivo da presente invenção, propor uma máquina com uma broca semi- esférica com pelo menos quatro raios de corte diamantado cujo primeiro raio de corte retire uma peça convexa da pedra bruta seguida de mais quatro cubas de dimensões decrescentes.  [0006] It is an object of the present invention to propose a machine with a semi-spherical drill bit with at least four diamond cutting radii whose first cutting radius removes a convex piece of rough stone followed by four further decreasing-size vats.
[0007] É objetivo da presente invenção, propor uma máquina de eixo de mandril translacionalmente estático em relação a plataforma basal, que é pivotante em relação ao mesmo. O sentido de rotação da broca e da plataforma é invertido, a fim de facilitar o corte do bloco maciço que é auxiliado por um aspersor de água frontal a aludida broca.  It is an object of the present invention to propose a translationally mandrel spindle machine with respect to the basal platform, which is pivotal with respect to it. The direction of rotation of the drill and the platform is reversed in order to facilitate the cutting of the massive block which is aided by a front water sprinkler to the aforementioned drill.
Sumário da invenção Summary of the invention
[0008] A MÁQUINA DE BROCAR EM PEDRA BRUTA OU POLIDA PARA OBTENÇÃO DE CUBAS DE PIAS em questão, com pelo menos um cabeçote de giro, preferencialmente dois cabeçotes, do qual se projeta uma broca semi-esférica com pelo menos quatro raios de corte diamantados que adentram o bloco de pedra maciço posicionado na plataforma basal, que tem movimento pivotante em relação ao eixo do mandril da broca, assim como movimento de giro inverso ao da broca, de forma que ao girarem a máquina adentra dito bloco perfazendo cortes entre as quatro cubas de dimensões decrescentes das laterais para o centro, de onde é retirado um tampo convexo seguido de três cubas semi-esféricas e por fim uma cuba semi- esférica com laterais quadrada ou retangular. [0008] THE GROSS OR POLISHED STONE DRILLING MACHINE FOR SAVING TUBE TUBES, with at least one swivel head, preferably two heads, from which a semi-spherical drill with at least four diamond cutting radii is designed entering the solid stone block positioned on the basal platform, which has pivoting motion in relation to to the axis of the drill chuck, as well as reverse rotation of the drill, so that as the machine is rotated into the block making cuts between the four decreasing sinks from the sides to the center, from which a convex top is removed followed by of three semi-spherical vats and finally a semi-spherical vat with square or rectangular sides.
[0009] A máquina tem como principais dispositivos o mandril que funciona estático em relação a plataforma basal pivotante a 90Q, mandril e plataforma basal girando em sentidos inversos. A broca é escalonada de contorno semi-esférico com quatro raios de corte, o que possibilita com o giro da plataforma basal sobre o mandril perfazer o corte das quatro cubas e um tampo convexo menor. Na plataforma existe uma gaveta para recepção do bloco de pedra maciço, retangular ou quadrado, que deve ser adequadamente fixado antes da referida plataforma entrar em movimentação radial e pivotante em direção ao mandril. [0009] The machine has as its main devices the mandrel that works static with respect to the pivoting 90 Q basal platform, mandrel and rotating basal platform in reverse. The drill is staggered with a semi-spherical contour with four cutting radii, which makes it possible to rotate the basal platform over the mandrel to cut the four wells and a smaller convex top. On the platform there is a drawer for receiving the solid, rectangular or square stone block, which must be properly fixed before said platform enters radial and pivoting movement towards the mandrel.
[0010] O broqueamento do bloco maciço, bruto ou polido, se inicia quando a gaveta da plataforma basal entra em operação ao girar em sentido contrário ao da broca e pivota na direção do mandril fazendo com que o maior raio de corte encoste na pedra e assim sucessivamente até o menor raio de corte numa evolução até o maior ângulo de pivotamento da aludida plataforma basal onde um fim de curso a obriga retornar para a posição horizontal. Neste curso da plataforma basal todos os raios de corte penetram um pequeno espaço do bloco maciço para efetivar o corte completo das cubas / tampo.  Boring of the rough or polished solid block begins when the basal platform drawer comes into operation by turning counterclockwise and pivoting toward the mandrel causing the largest cutting radius to touch the stone and thus successively to the smallest radius of cut in an evolution to the greatest pivot angle of the alluded basal platform where a limit switch forces it to return to the horizontal position. In this course of the basal platform all the cutting radii penetrate a small space of the solid block to effect the complete cutting of the vats / top.
[001 1 ] Assim, do bloco maciço são retirados no mínimo três cubas semi-esféricas de dimensões escalonadas decrescentes, uma cuba semi-esférica de lateral quadrada ou retangular e um tampo convexo que pode servir a um banco ou banqueta, desse modo reduzindo substancialmente as perdas quando da comparação com os processos citados no estado da técnica.  Thus, from the massive block at least three semi-spherical vats of decreasing staggered dimensions, one square or rectangular semi-spherical vat and a convex top which can serve a bench or stool, are substantially reduced. losses when compared to the processes cited in the prior art.
Vantagens da invenção Advantages of the invention
[0012] Em suma, a invenção pleiteada apresenta como vantagens mais preponderantes:  In short, the claimed invention has as its most prominent advantages:
■ Redução dos custos da operação. ■ Reduction of operation costs.
■ Utilização de quase todo o material desbastado para obtenção da cuba. ■ Use of almost all roughed material to obtain the bowl.

The through shaft (13) has the function of supporting the basal platform (6) which is pivoted in the direction of the drills (4) as a function of the gear (10) and encoder (11).
[0018] Acima da plataforma basal (6) há os cabeçotes (A e B) estruturados a partir de chapas devidamente dimensionadas, projetadas para recepcionar os motores (2), mandris (3) e brocas (4) posicionados na vertical sem liberdade de movimento de translação apenas de giro inverso ao das gavetas (5) contidas na plataforma basal (6). Above the basal platform (6) are the heads (A and B) structured from properly sized plates designed to accommodate the motors (2), chucks (3) and drills (4) positioned vertically without freedom of movement. movement of only reverse-rotation translation of the drawers (5) contained in the basal platform (6).
[0019] A broca (4) semi-esférica tem quatro raios de corte diamantados (R1 , R2, R3, R4) cada qual correspondente a uma cuba (C1 , C2, C3, C4) e o raio (R4) ao tampo (T).  The semi-spherical drill bit (4) has four diamond cutting radii (R1, R2, R3, R4) each corresponding to a bowl (C1, C2, C3, C4) and radius (R4) to the top ( T)
[0020] Por fim, a máquina (1 ) possui uma rede hidráulica configurada por tubos "T" aspersores (7) que refrigeram a broca (4) e também pulverizam o bloco maciço (Β') durante o corte, ficando ditos tubos sob a broca (4) e no eixo das gavetas (5).  Finally, the machine (1) has a hydraulic network configured by sprinkler "T" pipes (7) which cool the drill (4) and also spray the solid block (Β ') during cutting, said pipes being under the drill bit (4) and the drawer shaft (5).
[0021 ] O funcionamento da máquina (1 ) se dá com a colocação do bloco maciço (Β') na gaveta (5) presente na plataforma basal (6), podendo-se utilizar uma ou as duas gavetas (5). Após a fixação do bloco maciço (Β') el ou fechamento da gaveta (5), num painel de comando, é ligada a gaveta (5) e a broca que giram em sentidos opostos. Em seguida inicia-se o pivotamento da plataforma basal (6) na direção dos cabeçotes (A, B), onde a engrenagem (10) e o conjunto de encoder (1 1 ) perfazem uma velocidade de giro lenta e controlada, a fim de encostar o primeiro raio de corte (R1 ) na cuba de maior dimensão (C1 ), e conforme a plataforma basal for pivotando na direção de 90Q os outros raios de corte (R2, R3, R4) vão cortando as cubas menores (C2, C3, C4) e por fim ficará o tampo (T) convexo. Ao atingir os 90Q um fim- de-curso obriga a plataforma basal (6) retornar para a posição horizontal, sendo que nessa posição basta abrir a gaveta (5) e soltar manualmente as peças (C2, C3, C4 e T) entre si com o auxílio de um soquete de madeira. The machine (1) can be operated by placing the solid block () ') in the drawer (5) on the basal platform (6), using one or both drawers (5). After fixing the solid block (Β ') 1 and closing the drawer (5) on a control panel, the drawer (5) and the rotating drill in opposite directions are connected. Then the pivot of the basal platform (6) begins towards the heads (A, B), where the gear (10) and the encoder assembly (11) make a slow and controlled turning speed in order to abut the first cutting radius (R1) in the larger bowl (C1), and as the basal platform pivots towards 90 Q the other cutting radii (R2, R3, R4) will cut the smaller vats (C2, C3, C4) and finally the top (T) will be convex. When reaching 90 Q a limit switch causes the basal platform (6) to return to the horizontal position, in which position simply open the drawer (5) and manually release the parts (C2, C3, C4 and T) between itself with the aid of a wooden socket.
[0022] Importante ressaltar que a gaveta (5) tem o movimento de giro oposto ao movimento da broca (4), o que gera condições para um corte eficiente do bloco de pedra maciço (Β'). Um aspecto importante de ressaltar é que pelo fato de ser uma broca (4) diamantada, durante o corte já é feito o polimento da pedra / cuba / tampo.  Importantly, the drawer (5) has the rotating motion opposite the movement of the drill (4), which creates conditions for efficient cutting of the solid stone block (Β '). An important aspect to note is that because it is a diamond drill (4), the stone / bowl / worktop is already polished during cutting.
[0023] Em todo o processo de fabricação a rede hidráulica é mantida ligada, fornecendo água, o que além de refrigerar evita a geração de pó durante o corte. Throughout the manufacturing process the hydraulic network is kept connected, providing water, which besides cooling prevents dust generation during cutting.
[0024] Como já comentado, as cubas (C1 , C2, C3, C4) e o tampo (T) recortados do bloco maciço (Β') permanecem fixos entre si por uma pequena seção central, separados por meio de batidas fracas realizadas por soquetes de madeira que deslocam as peças. A parte central da cuba que fazia a união entre elas torna-se um espaço apropriado para ser perfurado para recepcionar a válvula da pia. As already mentioned, the wells (C1, C2, C3, C4) and the top (T) cut out of the solid block (Β ') remain fixed to each other by a small central section, separated by light beats performed by wooden sockets that move the pieces. The central part of the bowl that joined them becomes a suitable space to be drilled to receive the sink valve.
