The steel cage roll welding machine is a mechanical equipment for mechanized production of steel cages. The CNC rebar cage welding machine is a kind of equipment that uses programmable controller and variable speed drive system to process and produce rebar cages.
Compared with traditional manual lashing, the CNC steel bar cage welding machine greatly improves production efficiency, reduces labor input, and greatly improves product quality.
Equipment composition and working principle
The mechanical system of the steel cage seam welding machine consists of a frame, a traveling trolley, a fixed disk mechanism, a movable disk mechanism, and a fixed support disk group; the traveling trolley, fixed disk mechanism, and movable disk mechanism are respectively driven by a variable speed drive system, as shown in the following figure:
According to the construction requirements, first pass the main rib through the circular hole of the corresponding template in the fixed turntable to the corresponding hole of the mobile turntable for fixing. The end of the winding bar is welded to a main bar first, and then the winding bar is wound around the main bar by rotating the fixed turntable and the moving turntable, and welding is carried out at the same time until the end of the main bar is welded to the specified position to form the product steel cage. At the same time, the spacing of the winding steel bars (cage spacing) can be set. The cage spacing control is divided into two modes: the overall cage spacing and the segmented cage spacing. In the segmented cage spacing mode, up to 7 different cage spacings can be set.
After starting the equipment, the moving plate and the fixed plate rotate at the same speed, and the moving plate moves at a certain speed at the same time to form a wound steel mesh with a certain interval. During the processing, the position of the movable plate and the fixed plate must be consistent to ensure that the main steel bars are not twisted. To this end, an encoder is installed on the rotating shafts of the movable disk and the fixed disk to measure their respective positions and to correct the control when there is a position deviation.
Control system composition
The whole system consists of Alpha's touch screen, PLC, 6000E inverter or AS600 asynchronous servo system. PLC communicates with each drive inverter through RS458, sends speed command and obtains running status.

System Features
Compared with traditional processing methods, CNC rolling cage welding machine has obvious advantages, the specific performance is as follows:
01. Fast processing speed
It realizes automatic control, only 2 people are required to load materials, and only 1 person is required to operate during normal operations. The work efficiency is very high.
02. The processing quality is stable and reliable
Due to the use of numerical control mechanized operation, the spacing between the main reinforcement and the winding reinforcement is uniform, and the diameter of the steel cage is the same. The product quality fully meets the specification requirements, and it can almost be free from inspection.
03. Improve subsequent production efficiency
Stirrup tightening does not require lap joints, which saves 1.5% of materials compared with manual work and reduces construction costs; because the main reinforcement is evenly distributed on its circumference, it is convenient when multiple steel cages are overlapped, saving lifting time.
04. Quality and accuracy guarantee
The mechanized processing of steel cages is guaranteed in terms of quality control and processing accuracy.
