推广应用双钢筋技术关键在于研制双钢筋自动焊机。我所自1980年开始用了二年半时间研制出XSH-120双钢筋自动焊机(见图1),经过生产考核并组织技术鉴定,认为该机结构紧凑,体积小,设计合理,连续运转性能良好,工作稳定可靠,自动化程度和生产率都比较高,焊接的双钢筋质量符合双钢筋暂行条例规定。
The key to the promotion and application of double steel bar technology lies in the development of double-bar automatic welding machines. Since 1980, we have been developing the XSH-120 double rebar automatic welding machine (see Figure 1) for two and a half years since 1980. After the production evaluation and the organization of technical appraisal, we believe that the machine has a compact structure, small size, reasonable design and continuous operation. The performance is good, the work is stable and reliable, the degree of automation and productivity are relatively high, and the quality of welded double steel bars is in accordance with the regulations of the double steel provisional regulations.
