Steel pipe thermal flattening plate forming machine

Abstract

The invention discloses a steel pipe thermal flattening plate forming machine. The machine comprises a machine base, and a steel pipe input device, a pipe cutting-open device, an expanding device and a flat plate device are sequentially arranged on the machine base. The pipe cutting-pen device comprises a rolling cutting roller rotationally installed on the machine base, a rolling cutting outer blade is arranged on the rolling cutting roller, a rolling cutting base located in an inner cavity of a steel pipe is fixedly arranged on the machine base, and a rolling cutting inner blade corresponding to the rolling cutting outer blade is rotationally installed on a rolling cutting base. The rolling cutting roller is connected with a rolling cutting driver, and a rolling cutting holding mechanism corresponding to the steel pipe is arranged on the rolling cutting roller and / or the machine base. Steel pipes input by the steel pipe input device can be continuously cut open, then are expanded by the expanding device to be in an approximate flat plate shape, and then are rolled by the flat plate device to form a plate with the required thickness. According to the machine, waste steel pipes are converted into steel plate resources for use, the conversion effect is good, and the conversion efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a steel pipe thermal flattening machine. Background technique [0002] A steel pipe is a steel material with a hollow section and a length much greater than its diameter or circumference. It is widely used in engineering, thermal power, petrochemical, machinery manufacturing and other fields. Regardless of the production of steel pipes or the use of steel pipes in various fields, waste pipes or old pipes will inevitably be produced. Among them, such as the old oil pipes regularly replaced in the oil field, they can also be re-hot-rolled for use, but such as unqualified waste pipes produced in production, or even old pipes that are worn or corroded seriously in various fields, are difficult to replace. Recycling is completed through hot rolling. Even old oil pipes that can be used after hot rolling are very likely to become useless due to the purchase and use of new oil p...

Problems solved by technology

Among them, such as the old oil pipes regularly replaced in the oil field, they can also be re-hot-rolled for use, but such as unqualified waste pipes produced in production, or even old pipes that are worn or corroded seriously in various fields, are difficult to replace. Recycling is completed through hot rolling. Even the old oil pipes that can be used after hot rolling are very likely to become useless due to the purchase and use of new oil pipes.

In addition, affected by the steel market and management policies in various fields, it is difficult to realize the sale and utilization of waste steel pipes in various fields
