Abstract

MáQUINA DE DOBRAMENTO DE CANO COM MANDRIL DE DOBRAMENTO TENDO UMA ESTRUTURA DE MANCAL DE CARGA QUE E PARTICULARMENTE RESISTENTE A TENSõES DE TRABALHO Máquina de dobramento de cano com mandril de dobramento com uma estrutura de mancal de carga que é particularmente resistente a tensões de trabalho, que compreende um extrator (2) que é fixado em uma porção posterior da máquina de dobramento de cano, sendo que uma haste de mandril (13) se estende com o próprio eixo geométrico longitudinal (g) do extrator além de uma porção frontal da máquina, onde uma cabeça de dobramento (7), que é fornecida com uma matriz (8), tensiona um cano (T) paradobrá-lo, e que é inserido em um mandril (12), através da tração resultante da força transmitida ao longo da haste de mandril (13) para o extrator (2) que se contrapóe a uma reação restritiva resultante. A máquina de dobramento de cano compreende uma estrutura de mancal de carga (1) tendo um perfil contido em um eixo geométrico longitudinal (g) da haste de mandril (13), de forma que a estrutura de mancal de carga (1) é submetida principalmente a tensão de compressão. PIPE BENDING MACHINE WITH PIPE BUCK HAVING A LOAD BEARING STRUCTURE THAT IS PARTICULARLY RESISTANT TO WORKING BENDING PIPE BENDING MACHINE WITH A LOADING BEARING STRUCTURE comprises an extractor (2) which is fixed to a rear portion of the barrel bending machine, a mandrel rod (13) extending with the extractor's own longitudinal axis (g) beyond a front portion of the machine, where a folding head (7), which is provided with a die (8), tensiones a barrel (T) to bend it, and which is inserted into a mandrel (12), through the resulting pull of the force transmitted along the arbor rod (13) for the extractor (2) which counteracts a resulting restrictive reaction. The barrel bending machine comprises a load bearing structure (1) having a profile contained in a longitudinal geometric axis (g) of the mandrel shank (13), such that the load bearing structure (1) is subjected. mainly the compression stress.
