Problems solved by technology

[0002] Due to forming or splicing errors, it is often difficult to shape the pipe fittings out of round. Usually, the shaping method is to repress the pipe fittings in the forming mold to complete the round diameter. This method cannot round the concave part of the diameter of the pipe fittings.

Embodiment Construction

[0010] Start the hydraulic system, and press the manual control valve 6 to control the cylinder 3 pull rod to reach the top dead center upward. Put the nozzle of the pipe fitting downward into the pipe support of the corresponding specification, press the manual control valve 6 to change direction, control the pull rod of the oil cylinder 3 to slowly shrink downward, drive the mandrel 2 to go down, and its conical surface presses the inner conical surface of the arc support 1 to expand outward. The diameter of the pipe support is increased, and the inner wall of the nozzle of the pipe fitting on the pipe support is gradually attached to the outer surface of the pipe support, thereby realizing the expansion and full circle of the pipe opening.

Abstract

A pipefitting flaring round shaping machine is composed of an arc support 1, a core shaft 2, an oil cylinder 3, a housing 4, a spring 5 and a manual reversing valve 6; a pull rod of the oil cylinder 3 shrinks to drive the core shaft 2 to descend, the conical face of the core shaft 2 compresses the inner conical face of the arc support 1, the arc support 1 is expanded outwards, the inner wall of a pipefitting pipe opening formed in the arc support in a sleeving manner is gradually and tightly attached to the outer round face of a pipe support, and therefore pipe opening expansion and round shaping are achieved; after a pipe opening is expanded, the pipe opening is molded through pressing, the pipe opening shape precision is greatly improved, the shaping quality is stable, operation is easy, the shaping efficiency is high, the machine is suitable for meeting the shaping needs of pipe fittings of multiple specifications, and the technical problem of steel plate pipefitting opening diameter sinking and shaping is solved.

Description

technical field [0001] The invention belongs to the field of metal plate, pipe or basic non-cutting processing in the international patent classification, and in particular relates to the expansion and rounding of the mouth of the pipe fitting. Background technique [0002] Due to forming or splicing errors, it is often difficult to shape the pipe fittings out of round due to forming or splicing errors. Usually, the shaping method is to repress the pipe fittings in the forming mold to complete the round diameter. This method cannot round the concave part of the diameter of the pipe fittings. Contents of the invention [0003] The invention solves the technical problem of sag shaping of the caliber of steel pipe fittings. By expanding the caliber and then pressing and forming, the shape accuracy of the nozzle is greatly improved, the shaping quality is stable, the operation is simple, the shaping efficiency is high, and it can meet the shaping needs of various specifications...
