1.0The whole machine include two main machinery parts:Main Welding System and Automatic Workpiece Conveying System.

 

1.1 The main welding machine is designed into Gate Type Frame.2Sets of Resistance Welding Transformers are built at both side of the main frame:Left and Right Position.

Each transformer will weld several points per time depending on the dimension of the condenser as controlling program to finish one line of welding points.

 

1.2 The welding parts are all adopted with the pneumatic pressurized system, the machine upper part install a number of welding cylinders, each welding cylinder provides the welding pressure to 8-13 pairs of welding points.

When welding,the welding electrode will press down as programmed process.

 

1.3 On the welding table,there is two welding trolleys and fixtures.On the trolley,there is one condenser welding mould on one trolley,the wire and tube are loaded to the welding mould manually,then the trolley is fed to welding position and weld automatically by Servo Motor,after welding come back to the original position again.

 

1.4 The whole welding process is controlled by PLC and Single-Chip Microcomputer.

Every welding parameter,such as welding press,welding current and time,press holding time,and so on,is controlled by 2sets of welding controller.

The welding current and welding time of each welding cylinder is adjustable separately.This make sure the welding machine can meet various requirement of different condenser.

 

2.0 Main Working and Welding Process of the Machine

2.1 Firstly, operator load the wire and tube to one of two the welding fixtures and moulds manually;

2.2 Secondly,press the foot switch or start button,the first welding trolley and mould with the wire and tube is fed to welding position by Servo Motor automatically;

2.3 Thirdly,as the program which have already been inputted to the welding controller and PLC,it will weld the tube and wire together automatically;

2.4 Forth,the trolley go forwarder with the workpiece to the next welding position and weld again,one line by one line until to finish the whole condenser;At the same time,the worker will load wire and tube to the second welding fixtures and mould manually.

2.5 Fifth,after the finish one whole condenser,the first trolley and mould go back to the original position;At the same time,the second welding fixture and mould which have already been loaded with wire and tube go ahead to the welding position to finish the welding process again.

2.6 Sixth,the worker will upload the welded condenser and load pre-cutted wire and tube again to the first welding fixture and mould.

2.7 The two welding fixture and trolley will work in turn. And so on
