Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0015] like figure 1 As shown, the thin-walled tube bending anti-deformation device is installed inside the thin-walled tube 3, and its function is to play a supporting role on the inner wall of the thin-walled tube 3 when it is bent, including at least three spherical supports 1 and spheres Connecting rope 2, in actual use, the specific number of the spherical support body 1 is determined according to the bending lengt...

The invention discloses a thin-walled tube bending anti-deformation device. The thin-walled tube bending anti-deformation device at least comprises three spherical supporting bodies and a ball connection rope; the center axis of each spherical supporting body is provided with a through hole, the ball connection rope penetrates through the through holes so that the at least two spherical supportingbodies can be connected in sequence; a fixed ball stop block is installed at one end of the ball connection rope, the other end of the ball connection rope is detachably connected with an adjustableball stop block, and the adjustable ball stop block is fixed to the ball connection rope in an encircling mode; the fixed ball stop block and the adjustable ball stop block can be used for preventingthe spherical supporting bodies from falling from the ball connection rope; and the adjustable ball stop block has the detachable function, the number of the spherical supporting bodies can be increased or decreased, or the gap between every two adjacent spherical supporting bodies is adjusted by adjusting the position of the adjustable ball stop block. The thin-walled tube bending anti-deformation device is suitable for different thin-walled tube bending angles and thin-walled tube lengths, the problem that the deformation zone of a thin-walled tube is shrunken in the bending process is solved, the structure is simple, installation and using are convenient, and the machining cost is low.
Description
technical field [0001] The invention relates to a thin-walled pipe bending anti-deformation device. Background technique [0002] During the bending process of the thin-walled tube, the outer side of the thin-walled tube will be affected by tension, resulting in the phenomenon of elongation of the outer side of the thin-walled tube and thinning of the tube wall. At the same time, the inner side of the thin-walled tube is compressed. The inner side is affected by different forces. After the thin-walled tube is bent, the roundness of the bent section of the thin-walled tube will often be poor, that is to say, the bent section of the thin-walled tube is a flat tube. In order to ensure the roundness of the thin-walled tube after processing, at present, a mandrel is mainly added inside the thin-walled tube. The function of the mandrel is to support the inner wall of the thin-walled tube when it is bent, so that it can The roundness of the bending section is guaranteed, so that t...
