Device for automatic welding of pipes

Abstract

The invention discloses a device for automatic welding of a pipeline. The device for automatic welding of the pipeline comprises a feeding mechanism, a welding mechanism and a receiving mechanism. Thewelding mechanism is welded to one side of the feeding mechanism, and the receiving mechanism is arranged on the side, away from the feeding mechanism, of the welding mechanism. The welding mechanismis composed of fixing screw rods, fixing sliding blocks, fixing motors, fixing supports, pneumatic three-jaw chucks, rotary motors, a welding working table, supporting rods, a fixing transverse beam,a lifting sliding groove, a lifting cylinder and the like. According to the device for automatic welding of the pipeline, a feeding cylinder and the pneumatic three-jaw chucks are arranged, construction speed can be improved significantly, and thus reasonable reduction of the construction period is achieved; under the action of a control panel, investment of machines and tools is reduced, and investment of manpower is reduced; working efficiency is improved; the overall cost is lowered; a blanking cylinder is arranged, and under the same prefabricated construction conditions, construction quality can be guaranteed, and the qualified rate of detection is improved; and in addition, by using automatic welding, molding of welding lines is artistic, and the automatic welding is superior to traditional manual electric arc welding.

Description

Technical field: [0001] The invention belongs to the field of welding technology, in particular to a device for automatic welding of pipelines. Background technique: [0002] During the installation of coal coke gasification (gasification, purification), synthetic ammonia, air separation and compressed air, and delayed coking in the oil refining sector, the pipeline construction workload is relatively large, and the quality requirements are high, while the pipeline construction procedures are complicated and the number of components is huge. . When the pipeline construction conditions are met, the construction period left for the pipeline installation is short and the task is heavy, and there will be a phenomenon of rushing the construction period, which will inevitably affect the quality of the pipeline installation to a certain extent. The existing pipeline welding device cannot not only guarantee the quality but also It can speed up the construction progress, regardless ...

AI Technical Summary

Problems solved by technology

[0002] During the installation process of coal coke gasification (gasification, purification), synthetic ammonia, air separation and compressed air, and delayed coking in the oil refining sector, the pipeline construction workload is relatively large, and the quality requirements are high, while the pipeline construction procedures are complicated and the number of components is huge.

When the pipeline construction conditions are met, the construction period left for the pipeline installation is short and the task is heavy, and there will be a rush for the construction period, which will inevitably affect the quality of the pipeline installation to a certain extent. The existing pipeline welding device cannot guarantee the quality and at the same time It can speed up the construction progress, regardless of the project quality, construction period, on-site civilized construction, centralized management and control of human and machine resources, etc., the income is far less than the expenditure, and huge social benefits cannot be obtained
