Device for bending hollow structural components

A device (10) for bending hollow structural components (100), comprising

• a receiving element (20);
• a mandrel shaft (40) for receiving the receiving element (20),
• at least two ball joints (30, 30′) forming a row of at least two ball joints (30, 30′) wherein the ball joints (30, 30′) of the row of at least two ball joints (30, 30′) are connected with each other and the row of at least two ball joints (30, 30′) is inserted into the receiving element (20) at a first end of the row of at least two ball joints (30, 30′),
• a ball-and-socket joint (70), wherein the row of ball joints (30, 30′) is lockable by the ball-and-socket joint (70) at a second end of the row of at least two ball joints (30, 30′) located opposite the receiving element (20),
• at least two shingles (50, 50′), wherein each ball joint (30, 30′) of the row of ball joints (30, 30′) is circumferentially enclosed by one of the at least two shingles (50, 50′), and wherein one of the at least two shingles (50, 50′) and/or one of the ball joints (30, 30′) is rotatable and/or pivotable in all directions relative to each other, and
• an end shingle (60), wherein the ball-and-socket joint (70) is circumferentially enclosed by the end shingle (60), and one of the at least two shingles (50, 50′) and the end shingle (60) overlap each other at least in portions
• characterized in that one of the at least two shingles (50, 50′) and the end shingle (60) comprise a holding section (53, 63), wherein one of the ball joints (30, 30′) and the ball-and-socket joint (70) are insertable into the holding section (53, 63) in a positive locking manner and are pivotable in the holding section (53, 63).
