    • The invention is a flaring device (1) for flaring the ends of pipes (T), comprising a main body (2) that defines a longitudinal axis (X), in which it is possible to identify: a flaring unit (3) suited to flare the end of the pipe (T); a die carrier (10) arranged in front of and coaxial with the flaring unit (3) according to the longitudinal axis (X); a flaring die (8; 50; 60; 70; 80) configured so that it can be accommodated in the die carrier (10) and having a centre channel (9) suited to house the pipe (T). The die carrier (10) has a shaped seat (11) that houses the flaring die (8; 50; 60; 70; 80) and communicates with a shaped opening (14) present in the main body (2) and included between the flaring unit (3) and the die carrier (10). The shaped seat (11) is defined by a conical inner surface (12) whose taper diverges towards the flaring unit (3) and being configured so that it matches the conical outer surface (13) of the flaring die (8; 50; 60; 70; 80). The shaped opening (14) is made in the lateral surface (2a) of the main body (2) and its length (14a) exceeds the length (8a) of the flaring die (8; 50; 60; 70; 80), both measured along the longitudinal axis (X), while its width (14b) exceeds both the width (8b) of the flaring die (8; 50; 60; 70; 80) and the width (11b) of the shaped seat (11), measured crosswise with respect to the longitudinal axis (X).
    • 本发明是一种用于使管道(T)的端部扩口的扩口装置(1),包括限定纵向轴线(X)的主体(2),其中可以识别:适于 (T)的末端; 根据所述纵向轴线(X)布置在所述扩口单元(3)的前面并与之同轴的模具托架(10); 一个扩口模具(8; 50; 60; 70; 80)构造成使得它可以被容纳在模具托架(10)中并具有适于容纳管道(T)的中心通道(9)。 模具托架(10)具有容纳扩口模具(8; 50; 60; 70; 80)并与存在于主体(2)中的成形开口(14))连通的成形座(11),并且包括在 扩口单元(3)和模具托架(10)。 形状的座(11)由锥形的内表面(12)限定,其锥形朝向扩口单元(3)分叉,并且构造成使其与扩口模具(8; 50; 60)的锥形外表面(13)相匹配 ; 70; 80)。 成形开口(14)制成在主体(2)的侧面(2a)中,其长度(14a)超过扩口模(8; 50; 60; 70; 80)的长度(8a) 两者都沿着纵向轴线(X)测量,而其宽度(14b)超过扩张模具(8; 50; 60; 70,80)的宽度(8b)和成形座椅(11)的宽度(11b) ),相对于纵向轴线(X)横向测量。
