Pipe production process and pipe production equipment

Abstract

The invention discloses a pipe production process and pipe production equipment. The pipe production process comprises the steps of: 1) material inspection: checking the quality of a plate before blanking: (1) checking if the thickness, the length and the width of the plate met the requirements; and (2) checking if two wound edges of the plate are in parallel; 2) heating: heating a pipe blank to aneeded temperature firstly through a method of heating by a reflecting furnace after the plate is qualified; and 3) prebending: bending 1 / 3 of the plate width by upper and lower molds for the first time to form a J-shaped steel plate after feeding the heated pipe blank into an oil pressure bed by a conveying roller way for positioning, bending 1 / 3 of the plate width by the upper and lower molds relative to one end of the J-shaped steel plate for the second time to form a C-shaped steel plate, and finally, bending rest 1 / 3 of the plate width by the molds in the center of the plate to obtain around pipe cylinder. The pipe production process and the pipe production equipment improve the hardness and the wear resistance of the pipe through a quenching process, and can enable welding lines tobe uniform through a welding process.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a pipe-making process method and pipe-making equipment. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. But it is very cumbersome. In the ordinary pipeline production process, the pipeline is often unqualified due to the leakage of the weld seam, and the pipeline is not bent precisely enough to cause the pipeli...

Problems solved by technology

Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. But it is very cumbersome. In the ordinary pipeline production process, the pipeline is often unqualified due to the leakage of the weld seam, and the pipeline is not bent precisely enough to cause the pipeline size to be unqualified. Therefore, we propose a pipe making process method and pipe making equipment
