Automatic operation process
Each mechanism is at the original point, the mold car is at the material position, the induction signal of each cylinder is normal, manually put the workpiece into the mold of the mold trolley; after placement, automatically operation welding. Wait for the welding to send the trolley back to the material position. After taking the material, then reweighing the material. This goes back and forth

● The equipment is mainly composed of welding power supply, transformer, feed mechanism, welding pressure mechanism, positioning fixture, air path, cooling water structure, control system, etc.
● Welding transformer: 2 sets of intermediate frequency welding transformer, small volume, stable current, good welding quality.
● Welding pressure mechanism: cylinder drop produces pressure welding, electrode movement using linear guidance, accurate and stable guidance. The cylinder pressure is controlled by regulating valve. The upper electrode adopts inlaid structure to facilitate replacement and reduce waste, and the electrode adopts T-groove installation method can be replaced with different sizes of workpieces, convenient for welding different workpieces. The upper and lower electrodes can be fine-tuned to facilitate welding.
● Clamp positioning: Position the workpiece with the workpiece shape compression method to collect and put the workpiece.
● Air route: use the pressure regulating valve to control the cylinder pressure, the air source treatment including pressure regulating, filtration, lubrication, to improve the service life of the cylinder.
● The cooling waterway mainly cools the transformer, control box and electrode to ensure the service life of the power supply. The flow rate is installed with alarm device. Without cooling water, the welding is prohibited. The cooling water needs to be recycled and filtered to prevent water blockage.
● The movement and adjustment of the main components of the control system equipment can be directly set and controlled from the man-machine interface. The fault can alarm and display from the indicator light. The whole machine is controlled by PLC for operation6.8Equipment size: maximum welding width meters; maximum welding length meters
