Pipe fitting flattening and flaring tool

Abstract

The invention discloses a pipe fitting flattening and flaring tool. Flattening weld inspection and pipe end flaring of pipe fittings can be realized by a spotting force at the same time, and accordingly, working efficiency is improved; a rapid die changing structure is arranged in the tool, and dies can be replaced rapidly and accurately, so that working efficiency is improved remarkably, and diechanging time is reduced; a grating ruler is arranged in the pipe fitting flattening and flaring tool, and central positions of weld joints can be detected accurately.

Description

technical field [0001] The invention relates to the technical field of pipe making, in particular to a pipe fitting flattening and flaring tool capable of performing flattening welding seam detection and pipe end flaring on a pipe fitting at the same time. Background technique [0002] In the prior art, the flattening and flaring processes of pipe fittings are carried out independently in the tube crimping mold and the flaring mold respectively, and at least two driving mechanisms are required to respectively drive the crimping mold and the flaring mold to close the molds. On the one hand, the work efficiency is not high, on the other hand, it also increases the cost. In addition, the molds in the prior art need to be adjusted and corrected during assembly to ensure that the upper and lower molds are aligned. This adjustment and calibration process is quite time-consuming and labor-intensive, which affects work efficiency. In addition, pipe fittings are generally made by ro...

[0002] In the prior art, the flattening and flaring processes of pipe fittings are carried out independently in the tube crimping mold and the flaring mold respectively, and at least two driving mechanisms are required to respectively drive the crimping mold and the flaring mold to close the molds. On the one hand, the work efficiency is not high, on the other hand, it also increases the cost

In addition, the molds in the prior art need to be adjusted and corrected during assembly to ensure that the upper and lower molds are aligned. This adjustment and calibration process is quite time-consuming and labor-intensive, which affects work efficiency

In addition, pipe fittings are generally made by rolling plates, and then the first and last ends of the rolled plates are welded to form pipes. In order to determine the firmness of the welding, it is necessary to test the strength of the welds of the pipe fittings, and the welds The strength test is generally carried out through the pipe crimping process, that is, the pipe fittings are flattened to a certain extent, and whether the weld seam strength meets the requirements is judged by observing whether the weld seam is broken and whether the center line of the weld seam is offset, but now it is usually through Workers visually judge whether the centerline of the weld seam has shifted during the flattening process. This detection method has large errors and uncertainties.
