Abstract
The invention discloses a two-layer copper brazed steel pipe forming unit, comprising a horizontal unreeling machine, a pipe-making forming machine, an induction heating brazing furnace, a cooling device, cleaning, air-drying and flaw detection apparatus, and a reeling device, all of which are sequentially arranged parallel to each other, wherein the horizontal unreeling machine comprises an unreeling machine base, a rotating shaft and a discharge disc; the pipe-making forming machine comprises a nose box, a strip forming power mechanism, a forming nose, a mandril holder and a mandril; the induction heating brazing furnace comprises a brazing furnace frame, a brazing furnace cover and an induction heating device; the cooling device comprises a cooling pipe support and a cooling pipe; the cooling pipe is composed of an inner pipe and an outer pipe; the cleaning, air-drying and flaw detection apparatus comprises a cleaning liquid box, a pipe cleaning machine, an air-drying device, a pipe traction device, a flaw detection device and a cleaning liquid circulating pipeline; and the reeling device comprises a reeling trolley with a brake truckle, and a receiving disc. The two-layer copper brazed steel pipe forming unit is novel and reasonable in design, high in working efficiency, high in quality of a product, wide in application range, good in using effect and convenient to popularize and use.
Description
technical field [0001] The invention relates to a production equipment for double-layer brazed steel pipes, in particular to a double-layer brazed steel pipe forming unit. Background technique [0002] With the development of our country's society and economy, people's living standards continue to improve, the popularity of air conditioners, refrigerators, automobiles and other industries continues to increase, and the production capacity continues to expand. Therefore, the market demand for double-layer brazed steel pipes has continued to increase in recent years. [0003] At present, most of the production of double-layer brazed steel pipes in China relies on the experience of workers to adjust the tension of the mandrel and the temperature of the brazing furnace. The production methods are backward, the technical performance and stability are poor, the production efficiency is low, and it is difficult to meet modern manufacturing industry requirements. To improve the qua...
