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 steel pipe with a large diameter, a large wall thickness and a high steel grade. 【Background technique】 [0002] End face processing in steel pipe production usually refers to milling head chamfering processing, which is required for high-standard steel pipes, especially for petroleum fields, water and gas transmission fields, etc., the steel pipes used must require milling head chamfering processing The final quality must meet the corresponding standards. In recent years, with the implementation of my country's infrastructure projects such as the West-to-East Gas Transmission Project and the South-to-North Water Diversion Project, the market demand for high-quality steel pipes is increasing. With the development of large oil fields and natural gas fields, and international energy development cooperation, As we...
