Abstract
An apparatus for cutting pipes made of thermoplastic material, including: a tool for cutting pipes, an arm for supporting the tool which is movable between a non-operating configuration wherein the tool is disengaged from the pipe and an operating configuration wherein the tool is engaged in the pipe to exert a cutting action on the pipe, a lever which can be constrained to the arm, supporting device configured to move said lever, a locking unit for reversibly constraining said arm and said lever and disengaging means to move said arm from the operating configuration to the non-operating configuration.
Claims12
An apparatus for cutting pipes made of thermoplastic material in automatic cutter machines, comprising:
- a cutting tool for cutting pipes made of thermoplastic material,
- an arm, which carries said cutting tool, and movable in a rotational direction about a pin between a non-operating configuration, at which said cutting tool is disengaged from said pipe, at which said cutting tool is engaged with said pipe to exert a cutting action,
- a lever movable in a rotational direction about said pin between a rest configuration and an active configuration;
- a supporting device, operatively connected to said lever for moving the lever between said rest configuration and active configuration, said supporting device comprising a first electric actuator and a supporting body of said first electric actuator;
- and
- a locking unit operatively connected to the arm and to the lever and movable between an engaged configuration, at which said arm and said lever are made integral with each other by a constraint defined by said locking unit, and a free configuration, at which said arm and said lever are movable relative to each other;
- disengagement means configured to move said arm from the operating configuration to the non-operating configuration, when the locking unit is in the free configuration.
