Welding Production Line For Triangular Beam Steel Bar Trusses

1. Rubar laying frame

There are five sets of bar payoff stands, using rotating payoff method, with a maximum load of 2 tons.

Each payoff stand is equipped with independent air braking device.

Each payoff stand has an independent pre-straightening mechanism to remove the oxide scale on the surface of the steel bars.

2. Straightening and Feeding Mechanism

The Welding Production Line For Triangular Beam Steel Bar Trusses features a multi-roller straightening method, ensuring effective straightening without damaging the ribbed surface of the rebar. The feeding section is powered by three geared motors.

Each feeding mechanism can be controlled independently.

3. Steel Bar Storage Mechanism

The Welding Production Line For Triangular Beam Steel Bar Trusses adopts a new open-type storage rack for buffering and storage, which facilitates continuous production while effectively preventing rebar entanglement.

4. Terminal Straightening Mechanism

Secondary terminal straightening is performed on the main bar and the web bars before welding and forming. Five-roll straightening is used to ensure the straightness of the finished truss.

This mechanism plays a key role in adjusting the straightness of the truss products.

5. Web Bar Pressing and Feeding Mechanism

Swing-arm bending is used for bending the steel bars, powered by a servo motor, with good synchronization and high stability.

Steel bar bending is continuous (the bending mechanism works in a circular and up-and-down swinging motion, without delay), with fast forming speed.

The steel bar forming molds have cylindrical surfaces to prevent scratching the surface of the steel bars.

The feeding mechanism is powered by a servo motor, with better synchronization and accuracy. With the coordination of the bending mechanism, the perfect combination of the two servo motors can realize the function of changing the truss pitch without stopping, greatly improving the production efficiency.

6. Welding Part

Two spot welders, one on the top and one on the bottom, with two transformers in total. Four lower press rollers with good synchronization.

The welding cylinders have a small stroke, large force, fast welding speed, and high quality. The welding cylinders use high-quality brands and are air clamped.

The welding electrodes are made of chrome-zirconium alloy copper.

Equipped with positioning mechanism to ensure the shape and size of the welding.

The two-point resistance spot welding method reduces the installation power by 60% compared to peers, and the welding parameters of each welding point can be set independently.

The four-way electrode head can be reused four times, reducing the cost by 3 times.

7. Cutting Mechanism

The production line for triangular steel bar trusses employs a "shearing-style" cutting method, which effectively resolves the issue of weld cracking during cutting and prevents the trusses from deforming or twisting during the process.

Fast cutting speed, no need to stop welding.

For high-strength cutting at the main and side reinforcement welding joints, the latest developed high-strength and tough mold steel from China is used.

8. Automatic Collection and Stacking Mechanism

The automatic collection mechanism allows continuous production without the need to stop, improving efficiency.

It can collect trusses of different sizes, long and short.

The automatic collection, stacking, and shipping of trusses are all fully automated.

The automated collection and stacking device reduces the number of operators by 2.

9. Electrical Control System

It adopts the control system from Hechuan with high stability.

10. Operating System

Operating buttons and other components use high-quality products.

The equipment is easy to operate and adjust.

Operations such as speed, welding parameters, etc. are convenient.
