[Iterative Upgrade] Version 4.0 Of The Box Girder Bottom Web Frame Fully Automatic Welding Production Line Is Officially Launched!
Oct 11, 2025| [Version 4.0 of the fully automatic welding production line for the bottom web frame of the box girder] From the 001 Yanhuang Expressway to the 002 Shanghai-Nantong Project, from the 003 box girder frame exploration to the 004 iterative breakthrough - Version 4.0 of the fully automatic welding production line for the bottom web frame of the box girder has officially been launched!
1. Three-in-one fully automatic production line
01Technological Innovation
Abandoning the inefficient traditional mode of three sets of stirrups welded separately, the three-in-one stirrup forming of "standard section bending welding + diameter-reducing section bending welding + automatic loading" is realized, reducing the loss of process connection.
02 Unmanned Operation and Core Advantages
The entire process is coordinated by robotic arms-a gripper robot handles material transfer, a welding robot precisely performs welding operations, and a loading robot automatically stores finished products in a rotating magazine hopper, eliminating the need for human intervention.
This significantly reduces production space and the number of stirrup binding points, achieving a dual breakthrough in cost reduction and efficiency improvement.
2. Roof plate fully automatic production line
01
Sequencing process
The sequential operation of "automatic longitudinal reinforcement laying → intelligent stirrup bending → multi-head resistance welding" is adopted, and each link is accurately connected.
02
Technological Innovation
The innovative application of "double-group straightening + double-duct material storage" technology allows welding operations and material storage processes to be carried out simultaneously, avoiding work stoppages due to waiting for materials.
03
Collaborative work
The bending of stirrups and the welding of upper and lower layers are coordinated, and the skeleton conveying mechanism automatically pulls according to preset specifications, realizing seamless connection of streamlined operations and improving overall production efficiency.
3. Bottom plate fully automatic production line
Cost reduction and optimization
The base plate bars are flash-butt-welded to achieve "infinite length", reducing material loss; the wires are processed in advance and stored in a classified manner to reduce raw material waste.
Collaboration Mechanism
The turning mechanism, pushing device, feeding mechanism, traction mechanism and material shifting mechanism work together to realize assembly line production.
Accuracy guaranteed
The visual recognition welding robot adopts the "regional staggered welding" mode to realize the "welding and laying at the same time" cycle operation, which not only ensures welding accuracy but also reduces process waiting.
4. Future Outlook
We will continue to focus on technological iteration, deepen the application of intelligent construction in the field of roads and bridges, continuously optimize the efficiency and precision of production lines, and provide stronger scientific and technological support for the high-quality development of national infrastructure!
