Abstract

"UNIDADE DE AFROUXAR PARA OPERAR UM DISPOSITIVO DE APERTO PARA FERRAMENTAS". A presente invenção refere-se a uma unidade de afrouxar para operar um dispositivo de aperto para ferramentas. As ferramentas são fixadas com dispositivos de aperto em um assento de ferramentas de um fuso de ferramentas. Para soltar a ferramenta, um tirante é deslocado contra uma força de mola através de um elemento de afrouxamento com acionamento hidráulico ou pneumático. Os acionamentos hidráulicos ou pneumáticos são dispendiosos e onerosos. Para que a unidade de afrouxar possa ser executada de modo simples, económico e compacto, o acionamento da unidade de afrouxar é um motor elétrico. Ele pode ter uma construção simples, económica e compacta e precisa apenas uma linha de alimentação com corrente elétrica para a operação. A unidade de afrouxar é utilizada, por exemplo, em máquinas de beneficiamento de madeira.
