Pipeline connecting piece manufacturing and forming method

Abstract

The invention relates to a pipeline connecting piece manufacturing and forming method which mainly comprises the following steps of equipment inspection, pipe fitting installation, internal thread machining and finished product inspection. Pipe fitting connecting piece internal thread machining equipment comprises an installation frame, a fixing sleeve piece and forming sleeve pieces, the fixing sleeve piece is installed on the installation frame, and the forming sleeve pieces are symmetrically arranged at the two ends of the fixing sleeve piece. The pipeline connecting piece manufacturing andforming method can solve the following problems existing in internal thread machining forming of an existing pipe fitting connecting piece. The problems include that a, during internal thread machining forming of the existing pipe fitting, the pipe fitting often shakes, so that the position deviates during internal thread machining, the situation of internal thread machining failure is caused, the pipe fitting is scrapped, and raw materials are wasted; and b, when the existing pipe fitting is subjected to internal thread machining, an internal thread turning blade is often subjected to the action of large force, then the position of the blade deviates, the size of a thread is changed, and the product quality is affected.

Description

technical field [0001] The invention relates to the technical field of production of pipeline connectors, in particular to a manufacturing method for pipeline connectors. Background technique [0002] In construction and industrial production, in order to meet the needs of use, two steel bars or steel pipes are often connected together through connectors to form a whole, so pipe connectors are more commonly used in construction and industrial production. In production, in order to improve the stability of the connection, internal threads are often provided on the inner wall of the pipe connector, and the connection between the pipe fittings is made stronger by means of threaded connection. Now the pipe connectors often need to carry out equipment inspection, Steps such as pipe fitting installation, internal thread processing and finished product inspection. [0003] The existing pipe fittings often have the following problems when the internal thread is processed and formed...

AI Technical Summary

Problems solved by technology

[0003] The existing pipe fittings often have the following problems when the internal thread is processed and formed: a: When the existing pipe fitting is processed and formed with the internal thread, the pipe itself often shakes, which causes the position to shift when the internal thread is processed, resulting in The failure of internal thread processing occurs, which leads to the scrapping of pipe fittings and waste of raw materials; b: when the existing pipe fittings are processing internal threads, the internal thread turning blade is often subjected to a large force, and the position of the blade is shifted, making the thread The size changes, affecting product quality
