Abstract

The invention relates to the technical field of dies, and discloses a die for pipe flaring and a manufacturing method thereof.The manufacturing method comprises the steps that a, the length of a positioning block, the outer diameter of a limiting rod, the length of a pipe joint and the hardness grade of the positioning block are obtained; b, according to the data obtained in the step a, manufacturing parameters of the flaring die are determined; c, after the manufacturing parameters of the flaring die are determined, the flaring die is machined and manufactured through a machining machine tool, the length of the connecting sleeve is determined according to the length of the pipe joint, and then the length of the flaring pipe body is determined according to the length of the connecting sleeve; the drift diameter and the number of the through holes in the positioning block are determined according to the length of the positioning block, and the drift diameter is corrected according to the outer diameter of the limiting rod; the thickness of the positioning block is determined according to the hardness grade of the positioning block, the pipe fitting flaring die machined through the manufacturing method can improve the sizing precision, the roundness of a flaring pipe fitting is good, and the pipe fitting flaring efficiency can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of molds, in particular to a mold for flaring a pipe fitting and a manufacturing method thereof. Background technique [0002] At present, pipelines are widely used in daily life as a transmission medium. Pipes have an irreplaceable role in the field of home appliances, automobiles, machine tools and other fields. However, when the open end of the pipeline needs to be fixedly connected, it is Pipes need to be connected by means of joints, and the mold that needs to be flared at this time will flare the pipes. [0003] In the prior art, the method of manufacturing the flaring mold generally adopts the method of directly placing the flaring mold on the processing machine tool, which cannot be adjusted according to the actual situation. Therefore, the prepared flaring mold is relatively simple, and the molding effect is not good. The precision of the processed flaring mold is also not accurate enough. ...
