A high-strength 11-angle anti-unloading fastening nut with advanced domestic level has obtained the patent authorization of the State Intellectual Property Office.
The patent relates to a anti-unloading nut, in particular to a new anti-unloading nut which can be used on an electric power tower, and the 11-corner nut has the functions of fastening, anti-loose and anti-unloading, simple structure and strong practicability.
At present, after the bolts and nuts in the existing fastening technology are combined, since the common type nut has NO anti-theft protection device, it is easy to be used by a general-purpose tool, and is easily removed and taken away, thereby posing a safety hazard to related equipment and facilities. Even the loss of personal property, especially for outdoor facilities, such as the nuts on the transmission iron tower, the economic losses caused by theft are more prominent.
Shanghai Tianbao Fastener Manufacturing CO., Ltd. is a large-scale fastener industry. The factory is led by the engineer Gu Jiaxing. Under the leadership of the enterprise decision-making level, after more than a year of hard work, high-quality carbon The structural steel is used as raw material, and the required finished material is obtained by cold drawing and drawing. In the multi-station automatic cold heading forming machine, it is extruded by 5 steps, then tapping, and finally heat treatment and quenching and tempering to complete high strength 11 angle prevention. The test of unloading the tightening nut has entered mass production and achieved good economic benefits. The patent certificate number is: CN101033769.
The beneficial effect of the novel patented technology is that the raw material used is high-quality carbon structural steel, which is combined with heat treatment strengthening, and the 11-point anti-unloading fastening nut can play a high-strength and high-load fastening effect when threaded connection, and It is convenient to use its own structural features to prevent and unload, and has strong practicability.
At present, China's fastener industry is in a transition period from quantitative change to qualitative change. The high-end products of fasteners are insufficient, the low-end products are surplus, and high-end products are imported in large quantities. The export is mainly low-end products, which must be completed from low-end to medium-high. The transformation requires not only technical talents, but also new technologies and new products for fasteners.
Under the policy of reform and opening up, since 2001, Shanghai Tianbao Fastener Manufacturing Co., Ltd. has paid great attention to respecting labor, respecting knowledge and respecting talents. In recent years, the company has achieved a long-term development. Tons, annual output and sales of nearly 300 million yuan, most of the products are exported to Europe, Australia, Africa, America and Southeast Asia. They will gradually change the low-grade, low-price competition of fastener exports, and gradually transition to a new era of brand competition, to meet the big leap of fastener production.
