Embodiment 1

[0030] see figure 2 , the invention provides a method for processing a core tail of a hydraulically connected hose joint, which specifically includes the following steps:

[0031] Step 1. First, the thread rolling wheel 1 of the three-wheel thread rolling machine is pre-processed into the external dimensions of the core tail of the hydraulically connected hose joint;

[0032] Step 2, then select a metal tube 2 of suitable size, and put the metal tube 2 into the middle of the three thread rolling wheels 1 of the three-wheel thread rolling machine;

[0033] Step 3: Control the feed speed of the three thread rolling wheels 1, and extrude the metal tube 2 through the three thread rolling wheels 1 to obtain the desired shape and size of the core tail.

[0034] The metal pipe is a steel pipe.

Embodiment 2

[0036] see image 3 , the invention provides a method for processing a core tail of a hydraulically connected hose joint, which specifically includes the following steps:

[0037] Step 1, first pre-processing the thread rolling wheel 1 of the two-wheel thread rolling machine into the external dimensions of the core tail of the hydraulically connected hose joint;

[0038] Step 2, then select a metal rod 2 of suitable size, put the metal rod 2 into the middle of the two thread rolling wheels 1 of the two-wheel thread rolling machine, and the lower part of the metal rod 2 adopts a support 3 for support;

[0039] Step 3. Control the feed speed of the two thread rolling wheels 1, extrude the metal rod 2 through the two thread rolling wheels 1 to obtain the desired shape and size of the core tail, and then drill holes to obtain the hydraulic connection Cord tails for hose connectors.

[0040] The metal rod is round steel.

[0041] The material of the support 3 is fiber-reinforce...

Abstract

The invention discloses a processing method of a core tail of a hydraulic connection hose joint. In a forming technology, a three-wheel rolling machine or a two-wheel rolling machine is matched with a support to realize rolling forming. The processing method comprises the following steps: pre-processing a rolling wheel to the appearance size of the core tail by selecting a proper round steel or steel pipe, putting the rolling wheel into the round steel or steel pipe, and performing squeezing forming of three rolling wheels to obtain the required appearance and size of the core tail. The processing method has the benefits that the three-wheel rolling machine or the two-wheel rolling machine is matched with the support to realize one-time forming, so that the time is short, and the processing is facilitated; about 3,000 core tails can be processed one day; therefore, the production efficiency is greatly improved, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of fluid delivery of a hydraulic system, and in particular relates to a processing method for a core tail of a hydraulically connected hose joint. Background technique [0002] The existing core tail design of the hydraulic connection hose joint used in hydraulic pressure or other fields is composed of multiple grooves and steps. Usually, the core tail of the hydraulic connection hose joint is formed by turning, which takes a long time to process and is inefficient. A lathe can process up to 300 pieces a day, which requires multiple tools, lathes, CNC programming and other equipment and processes, and the production cost is high. In addition, traditional thread rolling machines generally roll threads, and there is no shape for rolling non-threads. [0003] For example: Chinese patent CN200810061360.7 discloses a manufacturing method of a hose elbow, including the following steps: a. material preparation: pre...
