High Safety Bolt Connection
YONGYI MANUFACTURING
DIGITALIZATION X INTELLIGENCE
Yongyi took the lead in the digital and intelligent transformation of the workshop, the use of customised automation equipment, industrial software, Yongyi's core technology and intelligent manufacturing, to achieve the whole process of lean production of bolts, nuts, washers, high-quality fasteners production capacity of up to more than 60,000 tonnes per year.
Hot heading automated production line
Independently developed advanced automatic hot forging lines, featuring round-coil heating with extended heating length and optimized R-angle design. By precisely controlling the heating and forging start temperatures, and eliminating water cooling during forming, effectively minimize the risk of forging failure throughout the process.
Cold heading automated production line
At normal temperature, the cold forging bolt and cold forging nut can be formed once. Less raw material loss in the production process, high production efficiency, energy saving and environmental protection.
Hot dip galvanized automated production line
Independently complete the hot dip galvanized production of all products, strictly implement the lSO 10684 standard and digitally control the entire process of hot galvanized, at present, five hot galvanized automated lines are configured to realize automated production and improve hot dip galvanized quality control.
Heat treatment automated production line
Having 6 continuous heat treatment mesh belt furnaces，strictly implement CQl-9 control management to ensure uniform and stable mechanical properties of quenched and tempered products.
Hobbing automated production line
Automatic loading and unloading, high production efficiency, stable output. Stable operation and accurate control precision.
YONGYI MANUFACTURING
INNOVATIVE TECHNOLOGY
Bolts, nuts and gaskets are produced in-house to achieve effective batch control, and at the same time to ensure the accuracy of the bolts, nuts and gaskets to improve the stability of the adaptability test of the connecting part.
Phosphate-free production
Improved the material lubrication process, to achieve the material conversion of non-phosphorus production, effectively avoiding the risk of phosphate generated by the fastener phosphorus brittle
No pickling process
The use of shot blasting process instead of the traditional pickling process, material treatment, surface treatment without acid washing, avoiding the risk of hydrogen embrittlement of the products brought about by acid washing.
Hot dip galvanized nut one- timetapping
All hot dip galvanized nuts, the thread is one- time tapped after hot dip galvanized，effectively improve the nut thread strength, avoiding nut detachment caused by secondary thread retraction.
Nut pre-coating process
Independent research and development of the coating line, while the use of advanced molybdenum disulfide pre-coating technology, coating of nuts, torque coefficient K control at 0.115-0.135, not only to achieve the adaptability of the test requirements, but also to achieve the gasket without pre-coating, to avoid the use of the process of rotation of the gasket caused by the problem of fastening failure.
