Information

Xining-Chengdu high-speed railway is an integral part of my country's "eight vertical and eight horizontal" high-speed railway network Lanzhou, and the Lanzhou (West) Guangzhou passage from Xining to Guangzhou. Across the three provinces of Qinghai, Gansu, and Sichuan, 60% of the road sections of the line are located above 3,000 meters above sea level, and the construction is extremely difficult. In particular, the tunnel construction needs to face altitude sickness and large temperature differences between day and night for a long time, which is very difficult for manual work and transportation. A great challenge.

 

Based on the advantages of the whole industry chain and rich welding application experience, STEP robots provide efficient, intelligent and flexible arch production solutions for the construction of Xicheng high-speed railway tunnels, and help China's rail transit develop by leaps and bounds.

Two-machine cooperation, efficient production

 

Production Process

 

√ H-shaped steel is automatically transported to the arch bending machine through the rails for arch bending processing

 

√ After the arch is formed, the size of the workpiece is determined by laser recognition technology, and then it is cut by a robot

 

√ The welding robot determines the shape and position of the workpiece through 3D vision, and then transmits it to the handling robot through Ethernet for assembly

 

√ After assembling, the welding robot will overall position the welding workpiece, and then weld the main position of the workpiece

 

STEP robot master-slave control technology enables welding robots and handling robots to cooperate with each other and produce efficiently; At the same time, double robot and double station design are adopted to double the efficiency; double platform stereotyped template The design effectively guarantees welding accuracy and processing efficiency, and can realize circular processing.

 

 

Adaptive flexible welding, reliable and consistent quality

 

Reconstruct the welding workspace through visual sensing, identify the position of the workpiece, and the welding robot moves to the initial welding position precisely. STEP welding robot SA6/1400 perfectly matches standard arc welding tasks with its 6kg load and 1400mm working radius, The streamlined design of the robot wrist ensures that the robot has the smallest destructive contour and the highest freedom of movement. Real-time detection and pre-processing during the welding process, online correction of the robot's trajectory and automatic adjustment of welding process parameters, beats are 20% higher than traditional contact positioning and line laser positioning, and are compatible with more than 100mm deviation The workpiece, guarantees the consistency and high reliability of weld formation and welding quality.      

 

 

Crack the labor shortage and achieve the fastest delivery

 

For the production of tunnel H-shaped steel arches, the demand for operating technicians is increasing, and the advantages of STEP intelligent welding system and traditional arch welding are prominent.

 

√ Using robots as carriers to realize highly flexible intelligent welding instead of manual labor

 

√ Compared with manual labor, it has higher work efficiency and more reliable welding quality

 

√ All points are generated by vision, and the whole system can be put into operation quickly

 

  Voice of the Customer  

 

"Due to the remote location of the project and the harsh environment, it is difficult to recruit workers. The high-quality products and services of STEP robots solve our worries. The high stability of the robot and the 24-hour rapid response service, for We provided stable and timely delivery capabilities, which is why we finally chose STEP." The person in charge of the project said. "

 

As the pioneer of robotic welding applications, STEP has taken the lead in many market segments. With the technical advantages of the 3D vision-guided intelligent welding system, the STEP robot has greatly expanded the application boundary of welding robots and met the new needs of the rail transit industry for intelligent welding.

 

In the future, STEP will continue to work with partners in subdivided industries to break through more welding technology difficulties, incubate more competitive welding solutions, empower partners, and jointly promote the progress and development of domestic robot welding business.
