CYW-1422垂直液压冷弯管机

CYW-1422 Vertical Hydraulic Cold Bending Machine

随着国家油气管道建设向着长距离、大输量不断发展,管道设计压力、管道直径不断加大,管材强度不断提高,这对管道施工装备提出了新的要求。为满足西气东输二线管道建设工程施工需要,研制国产大口径冷弯设备已成为当务之急。国产CYW-1422型垂直液压冷弯管机的研制;填补了国内空白,介绍了该产品的作用、工作原理和结构,在三维建模、主机、动力系统、内胎、弯管机自装卸装置、弯管过程数字化控制等方面创新优化设计,经强度分析、场内试验证明,设计制造技术先进,性能优质高效。产品获得广泛的推广应用,创造了可观的经济效益。

New requirements on pipeline construction equipment become inevitable because the country’s oil and pipeline construction is developing towards longer distance,larger transmission,larger diameter of pipeline and higher strength of tubular.To meet the demand for the construction project of second West-East Gas Pipeline,it is of great urgency to develop domestic large-diameter cold bending machine.Development of the domestic CYW-1422 vertical hydraulic cold bending machine fills the blank in China.This paper briefs about the functions,work principles and structures of this product as well as creative and optimistic designs in the areas of 3D modeling,main machine,power system,inner tire,self loading and unloading devices of bending machine and digital control over bending process.The indoor experiment indicates that the product is leading in design and manufacturing technology with high-quality and efficient functions.The product finds wide application and generates considerable economic revenues.
