Fixed Type Xy Axis Stainles Steel Stationary Pneumatic Resistance Welder Multi Point Spot Welding Machinery For Door Panels
Product Introduction:
The automatic spot welding machine for door panels uses pneumatic pressure and vertical movement of the upper electrode as its core action mode. Two electrode heads are arranged on the fixed welding machine to achieve simultaneous welding of two points, and is equipped with X and Y axis moving fixtures and fixture exchange racks. After manually clamping the workpiece, start the switch with both hands and move the workpiece to the welding position; The electrode is pressed tightly, and the thyristor conducts as needed to energize the primary of the transformer and generate welding current in the secondary; After the welding is completed, the thyristor is turned off, the electrode is lifted, the workpiece is displaced, and all points are cyclically welded. After completion, it is sent to the exchange rack. The overall length, width, and height of the machine are 5250 × 3775 × 2067mm, and it can weld elevator door panels of 0.5~1.5mm. The structure is simple and compact, energy-saving and environmentally friendly, and safe and reliable to use.
Features:
1. Power on interruption in the primary section of the transformer: only the thyristor is conducting during the welding period, and the power is completely cut off during standby, saving about 30% energy compared to traditional AC welding machines.
2. Low energy design of the pneumatic system: The cylinder stroke and pressure are matched as needed, combined with a quick exhaust valve to reduce compressed air waste.
3. Waterway circulation cooling: The built-in cooling system can recycle cooling water, reduce water resource consumption, and extend electrode life.
4. No harmful emissions: The resistance spot welding process is dust-free, arc free, and consumes no welding wire or electrode, and the workshop environment is clean.
5. Standby automatic sleep: The controller automatically cuts off the primary power supply of the transformer when there is no operation for a long time, resulting in low standby power consumption.
Detailed Images:
Double Electrode Head (up/down): A pair of copper alloy electrodes that directly contact the workpiece (welding 2 points at a time), apply current under pressure, concentrate heat on the contact surface of the plate to form a weld core, and complete spot welding.
X/Y Fixture Moving Mechanism: Driven by servo or stepper motor, the screw/synchronous belt accurately moves the workpiece in the horizontal plane, aligning the welding points of the door panel with the electrodes in sequence, achieving multi-point automatic welding.
Intermediate Frequency Control Box: Inverts AC power to DC power, achieving millisecond level high-precision welding, effectively reducing spatter, saving 30% energy, and significantly reducing transformer weight. It is particularly suitable for stable welding of materials such as aluminum and galvanized sheets.
Human Computer Interaction Interface: Touch screen or button panel, used to set welding parameters, call programs, display status and alarms, and achieve intuitive operation dialogue between people and devices.
