Jobsite Working Video
Gute Machinery steel bar truss automatic welding production line is a fully automated truss production line, which uses the functions of steel wire rod pay-off, steel bar straightening and automatic cutting to realize the automatic operation of truss welding. With the continuous development of truss technology, it has been widely used in the construction of buildings, railways, PCs and other projects. Compared with the manual tying of on-site construction, the prefabricated steel truss products not only reduce the amount of on-site steel tying by 50%-60%, but also shorten the construction period by 20%-30%. At the same time, truss welding realizes the integration of steel truss and bottom formwork welding, breaking through the traditional formwork, and realizing large-scale and standardized production. With the rise of prefabricated buildings, truss welding will be an indispensable equipment for the construction industry in the future .

Equipment Technical Advantages
The wave crest spacing between 190mm and 210mm is infinitely adjustable, and the precision can reach ±1mm. The upper and lower string bars are 12mm threaded steel, which has reached the highest level in the industry;
Mechanical shearing avoids the use cost of hydraulic system maintenance and hydraulic oil replacement;
With palletizing function, more labor saving；
The height of the truss is 70-300 infinitely adjustable, which has a wider application range, and the folding angle is optional；
The welding transformer is controlled by IGBT, which saves 30% of electricity compared with the traditional thyristor, which is energy-saving, environmentally friendly and economical。

Equipment Configuration Introduction
The equipment consists of five pay-off racks, storage racks, host, welding racks, shearing racks, conveying and packing racks, and operating tables.
Traction power: the main power adopts 16KW servo motor, which has strong power and good stability; the wave-rib adjustment device adopts servo-driven, CNC automatic adjustment to ensure the accuracy of the equipment;
Pay-off frame mechanism: Five groups of pay-off frames with brakes make the rebar pay-off smoother; the mechanism is equipped with no material alarm device, which makes the operation more humane.
PLC: The control system adopts German Siemens PLC, which has fast response time and more stable operation;
Pneumatic components: Adopt the well-known brand of Taiwan Airtac to ensure the service life; Baili cylinder adopts Weihe pneumatic, good stability;
