Basic Forming Equipment: Realizing the Preliminary Processing of Steel Bars
This type of equipment serves as the "first process" in steel bar processing, mainly completing the cutting, straightening, and bending of steel bars, thereby laying the foundation for subsequent high-precision processing.
Steel bar straightening and cutting machine:
It straightens coiled steel bars and precisely cuts them to the designed length. It can handle steel bars with diameters ranging from 6 to 40mm and serves as the starting point for processing main bars and stirrups in bridges.
Steel bar bending machine:
Divided into ordinary and CNC models, it bends straight steel bars into required shapes such as arcs and right angles for beams and columns. The precision of CNC models can reach ±1°, making them suitable for the complex reinforcement requirements of bridges.
Steel bar sawing machine:
Used for secondary cutting of straightened steel bars, it is available in mechanical and hydraulic models. The hydraulic type can cut thick steel bars with diameters exceeding 80mm and is used for heavy components such as bridge piers.
Steel bar bending center:
The steel bar bending center is a core piece of equipment in bridge engineering. Controlled by a numerical system, it can fully automatically bend long straight steel bars (12–40mm) into complex shapes such as U-shapes and arcs, with an angle accuracy of ±0.5°. It can batch-process steel bars 6–12m in length, greatly improving the efficiency and accuracy of steel bar processing for main beams, crossbeams, and other bridge components.
High-Precision Processing Equipment: Meeting the Special Reinforcement Requirements of Bridges
Large bridges (such as cable-stayed and suspension bridges) have extremely high requirements for the connection and forming accuracy of steel bars, thus relying on dedicated high-precision equipment.
Steel bar cutting, threading, and grinding integrated machine:
This machine integrates cutting, threading, and end grinding functions, reducing steel bar handling procedures. It is suitable for parts with high end precision requirements, such as embedded bars in bridge bearings, and helps avoid joint deviations during subsequent installation.
Steel mesh welding machine:
It welds multiple longitudinal and transverse steel bars into steel meshes. Available in semi-automatic and fully automatic models, the fully automatic type can perform continuous welding. It is used for bridge deck pavement and bridge pier reinforcement, significantly improving mesh flatness and welding efficiency.
Steel cage roll welding machine:
Specially designed for processing circular steel cages, it controls the winding spacing and welding points through a numerical control system. It can process steel cages with diameters ranging from 2 to 5 meters and lengths exceeding 30 meters, mainly used for bored cast-in-place piles in bridges.
