Abstract
A pipe flaring device is described. The device includes a main body extending along a mainly longitudinal direction. The main body also includes a flaring unit. The flaring unit interacts with an end of pipe to be flared. The main body also includes a die carrier arranged at the front of the flaring unit; and a flaring die. The flaring die includes a center channel which houses the pipe to be flared. The device includes a conical inner surface whose tapered end diverges towards the flaring unit and so that the inner surface matches a conical outer surface of the flaring die.
Claims18
A pipe flaring device comprising:
- a main body extending along a mainly longitudinal direction defined by a longitudinal axis;
- a flaring unit wherein said flaring unit interacts with an end of pipe to be flared;
- a die carrier arranged at a front of said flaring unit;
- and
- a flaring die wherein said flaring die is accommodated in said die carrier and provided with a center channel which houses said pipe to be flared;
- wherein said die carrier further defines a shaped seat which accommodates said flaring die and is in communication with a shaped opening defined in said main body, said shaped opening being located between said flaring unit and said die carrier;
- wherein said shaped seat defines a conical inner surface whose tapered end diverges towards said flaring unit and being configured so that it matches a conical outer surface of said flaring die;
- wherein said shaped opening is defined in a lateral surface of said main body, wherein a length of said shaped opening measured along said longitudinal axis exceeds a length of said flaring die likewise measured along said longitudinal axis, and wherein a width of said shaped opening, measured crosswise with respect to said longitudinal axis, exceeds a width of said flaring die and a width of said shaped seat, both measured crosswise with respect to said longitudinal axis;
- wherein said flaring die comprises two shaped cores that are joined to each other and are openable by an elastic rotation unit, and wherein a half of said center channel is defined in each one of said shaped cores;
- wherein said elastic rotation unit comprises a pair of pins comprising a first pin and a second pin, each coupled into a corresponding shaped core and arranged so that each pin passes through at least one joining bracket housed in a seat that extends over both of said shaped cores, wherein a helical spring is externally coupled with at least first of said pins, said helical spring having one end that is placed in contact with one of said shaped cores and a second end that interferes with the second pin.
