Abstract

Machining equipment for high-grade steel pipe end surfaces with large apertures and wall thicknesses comprises a fixed base, a movable base, a central gear transmission supporting device, a special power head and a feeding mechanism. The central gear transmission supporting device is fixed onto the movable base, the special power head consists of a portal framework, a large disc, a large disc supporting positioning mechanism, a large disc rotation transmission mechanism, a cutter head mechanism and two cutter head transmission phantom gear mechanisms, the cutter head mechanism comprises a chamfering cutter head mechanism and a plane milling cutter head mechanism, and a following mechanism is arranged above the chamfering cutter head mechanism. The machining equipment has the advantages that a rotation and revolution mode is adopted, chamfering of outer edges and machining of end surfaces of a steel pipe wall can realized by one-step machining, an automatic steel pipe finishing production line consists of the equipment, a feeding device, a clamping device and the like, accordingly the steel pipe machining range is greatly expanded, requirements of the petroleum industry and the like on machining of high-grade steel pipes with large apertures and wall thicknesses can be met, and the equipment is stable in running, high in machining capacity and efficiency and fine in quality.

Description

【Technical Field】 [0001] The invention belongs to the technical field of steel pipe finishing equipment, in particular to a processing equipment for the end face of a large-diameter, large wall thickness, and high-grade steel pipe. 【Background technique】 [0002] End face processing in the production of steel pipes usually refers to milling head chamfering. High-standard steel pipes need to be processed, especially in the oil field and water gas transportation field. The steel pipes used must require milling head chamfering and processing The quality afterwards must meet the corresponding standards. In recent years, with the implementation of my country’s infrastructure projects such as the West-East Gas Pipeline and the South-to-North Water Transfer Project, the market’s demand for high-quality steel pipes has increased. With the development of large oil and natural gas fields, international energy development cooperation, As well as the continuous increase in energy input and o...
