Problems solved by technology

In the traditional method, one end of the pipe is fixed, and then the other end is pressurized and bent by the pressure mechanism; such a bending method is likely to cause the internal closure of the pipe bend, and the pipe is often used for exhaust, drainage or oil discharge. If the inside of the pipe is blocked, the equipment using the pipe will not be able to operate normally, and even a safety accident may occur in severe cases

Embodiment Construction

[0016] The present invention will be described in further detail below by means of specific embodiments:

[0017] The reference signs in the accompanying drawings of the specification include: support table 1, bending plate 2, repair rod 3, cylinder 4, expansion block 5, rotating rod 6, round roller 7, servo motor 8, support rod 9, No. 1 connecting rod 10, No. 2 connecting rod 11, No. 3 connecting rod 12, pay-off stand 13, stay rope 14, pulley 15.

[0018] like figure 1 , 2 The pipe fitting bending tool shown includes a support platform 1, a bending plate 2, a cylindrical repair rod 3, an expansion mechanism, a transfer mechanism and a smooth transition mechanism. The right end of the bent plate 2 is hinged with the left end of the support platform 1 through a hinge, and the bent plate 2 is provided with a through groove. Repair rod 3 right ends are threadedly connected with support platform 1, repair rod 3 left corners are arc-shaped, the peripheral wall of repair rod 3 le...

Abstract

The invention relates to the field of pipe-fitting machining, in particular to a pipe-fitting bending tool. The pipe-fitting bending tool comprises a supporting table, a bending plate, a repairing rod, an expansion mechanism, a transferring mechanism and a smooth transition mechanism; the bending plate and the supporting table are hinged, and one end of the repairing rod is connected with the supporting table; a groove is formed in the circumferential wall of the repairing rod, and the expansion mechanism is arranged in the groove; the smooth transition mechanism comprises a rotating rod, a round roller and two flat-rolling mechanisms; and the transferring mechanism comprises two transferring units. During adopting the technical scheme, bending operation is conducted on a pipe fitting, meanwhile, arc stretching and repairing are conducted on the inner wall of the bending position of the pipe fitting, and the inner wall of the bending position of the pipe fitting is prevented from deforming; and meanwhile, the inner wall of the bending position of the pipe fitting is subjected to expansion, the situation that the interior of the pipe fitting is blocked during bending of the pipe fitting is prevented, then the outer wall of the bending position of the pipe fitting is subjected to flat rolling, and smooth transition at the bending position of the pipe fitting is achieved.

Description

technical field [0001] The invention relates to the field of pipe fitting processing, in particular to a pipe fitting bending tool. Background technique [0002] Pipe fittings are widely used in daily life. In order to meet the needs of use, it is often necessary to bend the pipe fittings. In the traditional method, one end of the pipe is fixed, and then the other end is pressurized and bent by the pressure mechanism; such a bending method is likely to cause the internal closure of the pipe bend, and the pipe is often used for exhaust, drainage or oil discharge. If the inside of the pipe fittings is blocked, the equipment using the pipe fittings will not be able to operate normally, and even a safety accident may occur in severe cases. Contents of the invention [0003] The object of the present invention is to provide a pipe bending tool that expands and repairs the inner wall of the pipe bend and performs smooth transition treatment on the outer wall of the pipe bend du...
