    摘要:This is a device used to weld the mounting ring on the shock absorber barrel of an automobile, using the resistance welding method. The main body is a 200KVA resistance welding projection welding machine. In order to ensure the accurate positioning and welding accuracy of the workpiece before welding, the welding machine is equipped with a positioning fixture for the mounting ring and the shock-absorbing cylinder. In order to ensure the reliability of the welding strength, the welding machine is also equipped with a high-performance welding controller, a high-current monitor for monitoring the welding process, and an electrode displacement monitor. At the same time, in order to ensure the reliability and safety of the welding machine, the welding machine is also equipped with air pressure, water flow, temperature, light curtain and other protective devices. In order to combine all these functions organically

In order to organically combine all these functions, make them work effectively and orderly, and display the status to the operator, the welding machine also has a powerful electrical control system. Use touch LCD as man-machine interface and **PLC as control center unit.

    2. Description of equipment composition
    1. Host
    1) Main technical parameters
      Model: TN-200Z
    Rated input power: single-phase 380V 50Hz
    Rated input power: 200KVA
    **Input power: 386KVA
    **Short-circuit current: 40000A
    ** Electrode pressure: 15000N (0.5MPa)
    Electrode stroke: 70+30mm (working stroke + auxiliary stroke)
     Cooling water flow rate: >16L/min
    2) Configuration
    Solder Mask Controller:
    Name    Quantity  Model     Brand
    Microcomputer controller 1 YF-0101Z2  Panasonic

    Electrode pressure mechanism:
    The main shaft movement pair adopts ball linear bearing to cooperate. The cylinder has a double-stroke function, the working stroke is used during welding work, and the auxiliary stroke is added when the electrode is maintained and replaced, so that the space between the electrodes is enlarged and the operation is convenient.

    Pneumatic system:
    The pneumatic system is equipped with a pressure switch and a digital pressure indicator. Only when the set pressure is reached, the welding machine can work. Each cylinder can be operated independently, except that the double-stroke cylinder and the holding electrode cylinder are assembled with imported parts, the other components are all SMC products. The electrode pressurizing circuit pipeline adopts 4-point steel pipe installation. Due to the large number of driving cylinders in this machine, in addition to the electrode pressurizing cylinder, there is also a holding electrode cylinder. Because the action sequence of each cylinder is different, some are double-stroke cylinders, and the working air pressure is different. Therefore, the pneumatic system of this machine is more complicated.
