Description

APERFEIÇOAMENTO EM INSERTO PARA CHANFRAR TUBULAÇÕES COM QUATRO E OITO ARESTAS DE CORTE E AINDA COM POSSIBILIDADE DE REAFIAÇÃO (RECUPERAÇÃO) DAS ARESTAS DESGASTADAS, UTILIZANDO  INSERT IMPROVEMENT TO CHANGE PIPES WITH FOUR AND EIGHT CUTTING EDGES AND STILL WITH THE POSSIBILITY OF REPLACEMENT (RECOVERY) OF WEARED EDGES, USING
SUPORTE COM CALÇOS INTERCAMBIÁVEIS  Support with interchangeable shims
O presente relatório se refere a um modelo de utilidade constituída por um aperfeiçoamento em inserto para chanfrar tubulações que atendam uma grande gama de diâmetros e paredes de tubos, com quatro e oito' arestas de corte, onde remodelações volumétricas e funcionais dos calços de apoio permitem o uso tanto de insertos de corte de quatro arestas como também de oito e ainda com possibilidade de reafiar as arestas desgastadas, resultando em uma usinagem robusta com acabamento melhor e uma indexagem mais segura e rígida, fatores primordiais para setores de tubulações petrolíferas, onde a conexão entre as tubulações necessitam de grande precisão a fim de evitar vazamentos ou acidentes.  This report refers to a utility model consisting of an insert enhancement for chamfering pipes that meet a wide range of pipe diameters and walls, with four and eight 'cutting edges, where volumetric and functional restorations of the support shims allow the use of both four-edged and eight-edged cutting inserts and with the possibility of sharpening worn edges, resulting in robust machining with better finish and safer and more rigid indexing, key factors for oil pipeline industries where The connection between the pipes need great precision in order to avoid leaks or accidents.
Atualmente, o estado da técnica conta com suportes dotados de plataformas de corte de apenas duas arestas, tal configuração não permite, sobretudo a reutilização dos insertos ou plataformas de corte acarretando com isso paradas sucessivas para remoção dos insertos desgastados para posterior troca por outro e desperdício da aresta de corte ao usinar outros tubos com dimensões diferentes.  Nowadays, the state of the art has supports with cutting edges of only two edges, such configuration does not allow, above all the reuse of the inserts or cutting platforms, thus causing successive stops to remove the worn inserts for later replacement and waste. cutting edge when machining other pipes of different dimensions.
Uma deficiência verificada nos presentes modelos em uso diz respeito ao uso de suportes onde os insertos de corte são fixados diretamente sobre o suporte, desta forma fica inviabilizada sua reafiação, pois assim seriam alteradas as configurações relativas à altura de centro de corte sendo que esta regulagem não está condicionada à máquina chanfradeira e sim unicamente ao suporte dos insertos de corte. Outro ponto a salientar seria quando há uma colisão da ferramenta, ou seja, geralmente quebra-se o inserto danificando o suporte, pois não há um calço para absorver tal impacto, ocasionando no sucateamento do mesmo ou na sua recuperação. A deficiency found in the present models in use concerns the use of brackets where the cutting inserts are fixed directly on the bracket, thus making it impossible to regrind, so that would be changed. settings concerning the height of the cutting center and this adjustment is not restricted to the beveling machine, but only to the support of the cutting inserts. Another point to note would be when there is a collision of the tool, that is, usually the insert is broken damaging the support, since there is no shim to absorb such impact, causing its scrapping or its recovery.
Assim o estado da técnica restringe o processo de chanframento oferecendo para isso apenas insertos com duas arestas de corte unicamente e sem a possibilidade de promover o afiamento destes insertos sem alterar com isso as alturas de corte recomendadas em relação ao suporte, ocasionando um alto custo produtivo e também restringe as possibilidades de faceamento do chanfro com restrições funcionais.  Thus the state of the art restricts the chamfering process by offering only two cutting edge inserts only and without the possibility of sharpening these inserts without changing the recommended cutting heights in relation to the support, resulting in a high productive cost. and also restricts bevel facing possibilities with functional constraints.
Com o intuito de solucionar tais deficiências, se desenvolveu o presente modelo de utilidade através de um aperfeiçoamento em suporte para chanfrar tubulações com plataforma de corte de quatro e oito arestas, resultando num dispositivo mais rápido, eficiente e com melhor custo x benefício.  In order to address these shortcomings, the present utility model has been developed through an improved support for beveling pipes with four and eight edge cutting platform, resulting in a faster, more efficient and more cost-effective device.
O que define a sofisticação do modelo de utilidade é fundamentalmente sua volumetria funcional permitindo o uso tanto de uma plataforma de corte ou inserto com quatro arestas como também de uma plataforma de corte de oito arestas.  What defines the sophistication of the utility model is fundamentally its functional volume allowing the use of both a four edge cutting or insert platform as well as an eight edge cutting platform.
O inserto ou plataforma de corte é fixado ao suporte ou porta-ferramenta por meio de parafusos tipo Torx, este suporte por fim é então fixado aos pares na máquina chanfradeira. O processo de chanframento consiste na remoção de material, pelo inserto de corte, na extremidade do tubo de acordo com a especificação requerida para tal, o faceamento resultante desta operação pode ser reto ou em ângulo. The insert or cutting platform is fixed to the holder or tool holder by means of Torx screws, this holder is then fixed in pairs to the beveling machine. The chamfering process consists of the removal of material by the cutting insert at the end of the pipe in accordance with the required specification, the facing resulting from this operation may be straight or angled.
O inserto é então utilizado até o desgaste da aresta de corte atingir um nível no qual não permita mais a sua utilização, partindo desta situação basta realizar a troca da aresta de corte realizando a inversão de lado do inserto e utilizando a outra aresta.  The insert is then used until the wear of the cutting edge reaches a level at which it no longer allows its use, from this situation simply changing the cutting edge by reversing the side of the insert and using the other edge.
A partir do momento em que se atinge o nível máximo de desgaste desta segunda aresta o procedimento seguinte é girar o inserto em cento e oitenta graus e passar unitizar terceira aresta de corte e assim se procede com a quarta aresta.  Once the maximum wear level of this second edge is reached, the next procedure is to rotate the insert one hundred and eighty degrees and then to unitize the third cutting edge and so on the fourth edge.
O diferencial do referido suporte compreende um sistema novo de fixação por meio de furo escareado e a utilização de calço dispositivo este que permitiu elevar o número de arestas de duas para quatro e numa segunda configuração de fixação para oito arestas de corte.  The differential of said support comprises a new countersunk hole clamping system and the use of shim device which has increased the number of edges from two to four and in a second clamping configuration to eight cutting edges.
Todavia, em virtude da reafiação dos insertos ocorrendo consequentemente remoção de material fato este que alteraria a altura de centro de corte, assim foi introduzido um segundo calço que faz a correção desta altura, mantendo com isso a configuração dimensionada para o corte e não alterando a condição inicial de usinagem. However, due to the re-sharpening of the inserts and consequently removal of material which would change the height of the cutting center, a second shim was introduced to correct this height, thus maintaining the dimensioned configuration for the cutting and not changing the initial machining condition.
Vale ressaltar, que a introdução do calço viabilizou a utilização de mais de um tipo de inserto com formato diferente com até oito arestas de corte, assim se pode utilizar um só suporte para insertos com diferentes números de arestas e caso ocorra colisão ou desgaste do alojamento do inserto que, na ocorrência de tal basta que se troque o calço sem a necessidade da troca dos suportes gerando com isso economia. It is noteworthy that the introduction of the shim made it possible to use more than one type of differently shaped insert with up to eight cutting edges, so that only one insert holder with different number of edges can be used and in case of collision or wear of the housing. of the insert that in the occurrence of such to change the shim without the need to change the brackets thus generating savings.
O aperfeiçoamento em suporte para chanfrar tubulações com plataforma de corte de quatro e oito arestas supre de todas as formas os modelos atuais ora conhecidos, onde por suas vantagens permite se dispor de um dispositivo mais eficiente, seguro e durável sendo desta maneira o objeto do presente modelo de utilidade, será mais bem descrito com base nos desenhos esquemáticos abaixo listados, mas não pretendendo o mesmo de gerar um caráter limitativo de proteção da patente  The support enhancement for chamfering four- and eight-edged cutting deck pipelines meets the present-day models in every way, where for its advantages it provides a more efficient, safe and durable device and thus is the object of the present. utility model, will be better described on the basis of the schematic drawings listed below, but not intended to create a limiting character of patent protection.
