Pipe Bending Tooling

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...
