Abstract

The invention provides a pipeline necking and crimping machine, a pipeline crimping method and a crimping pipe, which relate to the technical field of crimping equipment. The pipeline necking and crimping machine comprises abuckling and pressing main machine. The buckling and pressing main machine comprises a main machine body and an opposite opening and closing module. The opposite opening and closing module comprises a fixed mold and a movable mold; each of the fixed mold and the movable mold comprises a slot petal mold and a plurality of split petal molds, the slot petal molds are arranged on the opposite side surfaces of the fixed mold and the movable mold, and the slot petal molds on the two sides are matched with each other to form a combined split petal mold; and the split petal mold and the combined split petal mold are drawn close to the circle center of the arc at the same time to form an inner circle surface for clamping a pipeline. The pipeline necking and crimping machine is used in the pipeline crimping method. The crimping pipe is obtained by using the pipeline necking and crimping machine or the pipeline crimping method. By means of the pipeline necking and crimping machine, the technical problems that crimping is not firm and mechanical performance is affected in an existing crimping mode are solved, and the technical effects that crimping is firm and the mechanical performance is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of crimping equipment, in particular to a pipeline necking crimping machine, a pipeline crimping method and a crimping tube. Background technique [0002] With the continuous development and progress of my country's comprehensive national strength and socialist economy, the production and living standards of residents continue to improve, the power consumption continues to increase, and the demand for power supply is getting higher and higher. With the continuous expansion of the scale of power grid construction, especially in the construction of overhead transmission lines, the crimping process of wires is widely used. However, if any link in the crimping process causes improper operation, it will seriously affect the installation quality of the overhead power transmission line and cause accidents. [0003] Under the premise of increasing high-voltage level and long-distance transmission lines, in order to...
