Embodiment Construction

[0033] Referring to the drawings, 100 denotes an apparatus for butt jointing of elongated parts 101 and 102 having a common axis X. The device 100 includes:

[0034] - a body 20 extending along the axis x, the body 20 being hollow to define an axial chamber 30 having a side wall 33 , a first end face 31 and a second end face 32 ;

[0035] - a first enlarged portion 21 at the first end of the body 20, said first enlarged portion 21 defining a first bottom abutment 23 and a first top abutment 25;

[0036] - a second enlarged portion 22 at the second end of the body 20, said second enlarged portion 22 defining a second bottom abutment 24 and a second top abutment 26;

[0037] - at least one piston 40, comprising a front face 41 and a piston rod 42, said piston being housed in the axial chamber 30, thereby defining a chamber 50 in the axial chamber 30, said chamber 50 being able to be pressurized , said piston rod 42 rests against one of the end faces 31 or 32 of the axial chamb...

Abstract

The invention relates to a device (100) for connecting two elongate parts (101) and (102) end-to-end. The device comprises a body (20) extending along an axis x; the body is hollow to define an axial chamber (30) having side walls (33) , a first end surface (31) and a second end surface (32); a first enlarged portion (21), the first enlarged portion (21) is at the first end of the body, the first enlarged portion defines a first a bottom abutment (23) and a first top abutment (25); a second enlarged portion (22) at the second end of the body; said second enlarged portion defining a first Two bottom abutments (24) and a second top abutment (26); at least one piston (40) comprising a front surface (41) and a piston rod (42). said piston is received in an axial chamber defining a chamber (50) capable of being pressurized; said piston rod is in contact with one end face of said axial chamber; and means (52) said Means (52) for introducing / removing pressurized fluid into / from the interior of the chamber.

Description

technical field [0001] The present invention relates to an apparatus for butt jointing of elongate elements, in particular to an elastic contraction apparatus capable of forming a mandrel for solid elongate elements or long parts such as mandrels during rolling of seamless pipe ) butt or end-to-end splicing. The invention also relates to a method for butting elongated elements. Background technique [0002] In the heavy mechanical engineering industry it is often necessary to join sections of long solid parts while maintaining as much continuity of mechanical properties as possible. [0003] This requirement is especially important in the mandrel rolling industry for seamless tubes. In this process, a mandrel is arranged inside a tubular semi-finished product during rolling. It is often necessary to combine mandrels and extensions. This combination includes the mandrel, the extension, and the joint itself, and must ensure proper mechanical properties. The mandrel is usu...
