What is the car welding line?
Car Spot Welding Line is the most important process of the whole production line, It means to weld all the parts to the car body. The key equipments are the jigs and the welding system. Jigs are also called the welding fixture. The jigs are to improve the welding precision of the car body, and the car welding line uses the spot welding process to make the body have enough strength. For the customers, the CKD car production line will need the car welding line. It has high technical requirements.
The fully automatic car welding line is widely used in modern automobile enterprises. use the whole robot welding system and robot transfer system to make the high efficiency.
Car welding line process
Hexahedron assembly→Repair welding correction→Repair welding correction→Side panel bonding→Panel welding→Outer sealing
plate→Inner sealing plate→Cabin door installation→Gluing→Offline inspection→Transport
The Main Features of Welding Machine
(1) All double-sided single-point resistance spot welding is used for welding, which improves welding quality and reduces welding deformation and material consumption.
(2) The equipment is equipped with 4 sets of inverter welding systems. By adopting advanced electrode tracking technology, the upper and lower electrodes can be automatically aligned during welding and running, and 1+1 and 1+1+1 profiles are completed at the same time. Strip or 4 welds or welding, thus solving the technical problem of 1+1+1 profile welding by resistance welding.
(3) The electrical control system adopts a PLC controller with high precision and sets a separate control box and operation box. The control panel can display different vehicle serial numbers. The entire welding process of the equipment is automatically completed by pre-programmed procedures. The control center has a storage function, which can store a variety of models. When changing the model, the serial number can be switched, which makes it easy to weld a variety of models.
(4) The position of the welding point (height, width) is adjustable.
(5) The roof frame positioning device can be adjusted according to different models, which is more convenient.
(6) Double-drive gantry-type mechanism walks smoothly.
(7) Self-provided circulating cooling system and the cooling effect is reliable.
