Shanghai Hufeng Machinery participated in the high-strength steel bar technology exchange meeting
In order to implement the spirit of the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology's "Notice on the Promotion and Application of High-Strength Steel Bar Demonstration Work" (Jianbanbu  No. 13), according to the Ministry of Housing and Urban-Rural Development's guidance on the promotion and application of high-strength steel bars On April 24, 2013, the national high-strength steel mechanical connection technology exchange meeting of the China Construction Machinery Industry Association Steel Bar and Prestressed Machinery Branch was held at the Arcadia International Hotel in Langfang, Hebei. The theme of the meeting was "National High-Strength Rebar Mechanical Connection Technology Exchange Conference". Our company Shanghai Hufeng Machinery Co., Ltd. participated in the meeting with more than 150 expert representatives. Discuss and analyze the current situation of my country's steel mechanical connection industry, existing problems and development prospects, focus on the introduction of steel mechanical connection technology and connection sleeve standards, processing technology, quality control and new technologies for automatic processing, and explore common development and cooperation based on the current status of the industry A win-win approach.
The extensive application of high-strength steel bars and large-diameter steel bars has promoted the development of mechanical connection technology of steel bars in my country. The mechanical connection technology of steel bars in my country has been developed and applied since the middle and late 1980s. The first is sleeve cold extrusion connection technology (1987), followed by taper thread connection technology (early 1990s), upsetting straight thread connection technology (mid-1990s), rolling straight thread connection technology (mid-late 1990s) , and later the stripping rib rolling straight thread connection technology (1999). Rib stripping and rolling straight thread connection technology is the most widely used mechanical connection technology for thick steel bars in my country.
The main content of this exchange meeting: the current situation and development of my country's high-strength steel bar connection industry, technical problems in the application of high-strength steel bars, the development of rolling straight thread forming machines, special structure high-strength steel bar rolling straight thread connection technology, "Mechanical connection of steel bars" "Sleeve" industry standard introduction, the development status of special connection technology suitable for various special structure types, the development history and development direction of sleeve processing technology, etc.
Zhang Aiqin, general manager of our company, gave a keynote speech on the development trend of steel bar mechanical rolling straight thread forming machine, and comprehensively introduced rolling straight thread, direct rolling straight thread forming machine, shaping straight thread forming machine, rib stripping straight thread forming The characteristics and application of the machine; according to the industry standard of "sleeves for mechanical connection of steel bars" will be promulgated and implemented, further standardize the production of steel bar straight thread sleeves and improve the quality and efficiency of straight thread sleeves, the degree of automation and the improvement of steel bar straight thread At the same time, in order to reduce the labor intensity and improve the safety of production in the production process of steel bar straight thread sleeves, to create a better series of special equipment in China and to improve the degree of mechanical automation, our company has developed horizontal and vertical The advanced automatic sleeve tapping machine greatly improves the production efficiency. This speech was unanimously affirmed by the participants, and many representatives had in-depth exchanges and discussions with Mr. Zhang. After the meeting, the participating representatives collectively visited the steel bar straight thread rolling machine produced by our company, the newly developed automatic sleeve tapping machine and the fully automatic outer circle chamfering lathe, and exchanged and learned professional technical issues.
Finally, Lai Zhiyong, chairman of our company, was named the vice-chairman of the China Construction Machinery Industry Association Reinforcement and Prestressed Machinery Branch, and Shanghai Hufeng Machinery Co., Ltd. was named the vice-chairman unit of the China Construction Machinery Industry Association Reinforcement and Prestressed Machinery Branch. And came to the stage to commend and affirm.
After the meeting, the representatives of the meeting said that through this meeting, they have further strengthened their understanding of mechanical connections, are more confident in the prospects of the industry's development, have strengthened communication with upstream and downstream enterprises, and hope that the association will hold more similar exchange activities to broaden the horizons. vision.
